Preface This study was prepared for the Cape Cod Regional Technical High School. At the initial walkthrough for the project, Mr. Sanborn, Business Administrator for the school, informed us of the strong maintenance and improvement efforts to date: new unit ventilators at 1st and 3rd floors; retrofitted lighting, 2004-5; energy audit, 2004-5; energy efficient NSTAR rating; new membrane roof, 2005; new motor starters, 2008; new acoustic ceiling tiles; new generator; replaced cooling tower; repointing of masonry, sealing of windows, replaced some exterior doors; roof fan replacements. In the school’s pursuit of a maintenance and improvements program and schedule, the scope requested for this study was a general evaluation of existing conditions and systems and a prioritizing of system and building related needs. Among the items reviewed were the electrical system, including updating of the original switchgear; the hvac system, including the replacement of the boiler plant; the exterior envelope for window replacements and leaks; plumbing; interior finishes; site egress and accessibility. The study identifies remediation options for the items observed as needing repairs or replacement as well as associated costs. The final designer should review the study and satisfy himself to the accuracy of the contents before proceeding into design. However, it is expected that the study should save time and expense by avoiding unnecessary duplication of pre-design activities. In the meantime, it should be noted, that the MSBA has visited Cape Cod Technical High School (CCRTHS) in response to CCRTHS applications. The school is hopeful that new replacements and maintenance actions will be undertaken in the near future.

1. Executive Summary

(major issues, findings and recommendations.) Plumbing The Cape Cod Regional Technical High School has received minimal maintenance on plumbing and Fire Protection systems and equipment over its occupied years. Even with adequate maintenance, systems will gradually deteriorate due to normal scale development and poor water conditions. Although most of the systems are working adequately at this time, the major equipment and systems are near the end of their useful life. Along with aging systems, many of the systems are not up to current codes, such as…. Electrical In general, the electrical distribution system is original vintage. The electrical services are more than adequate in capacity but are in poor condition. Give Example These services are in need of immediate replacement. Life safety systems such as emergency lighting and exit signs have been modified as the original system has failed where area protection relays were provided. The fire alarm system is not ADA compliant and should be replaced. The life safety systems are in violation of today’s codes and would not be suitable for reuse under a renovation program with the exception of the emergency generator. The best of maintenance programs are intended to make equipment function properly within its expected life span. The emergency lighting and fire alarm systems have exceeded their expected useful life. It is our recommendation, taking into consideration the age and general condition of the existing equipment, that the life safety systems be replaced with new code compliant systems.

2. Introduction Cape Cod Regional Technical High School Cape Cod Regional Technical High School (CCRTHS) was built 1973-74 and was opened in 1975 to teach both traditional high school classes such as English, Math, and Science, along with offering students a variety of trades. Within its one building, CCRTHS supports 17 trade-related programs for approximately 680 daytime high school students as well as approximately 500 night time adult education and post graduates per year. Over the last 35 years, there have been a number of renovations to the building, such as the relocation of the library from the third floor to the first floor in 1996; the addition of classroom walls at the third floor a few years after the school was built; and a florist shop addition in 2004. Built in 1973, the typical exterior wall construction is a double wythe masonry wall. According to the original drawings, the wall is composed of (from interior to exterior) 8” cmu, 1” rigid insulation, air space and 4” jumbo face brick. The original drawings do not indicate that vapor or air barriers were used. Project History & Scope of Work Presently, the building and systems are showing their age and the need for new, more efficient mechanical, electrical, plumbing (MEP) systems. The objective of this study is to evaluate the conditions of the MEP systems; evaluate the conditions of the envelope of the building and the interior finishes; identify any code violations; and to recommend appropriate improvements with associated costs. In Spring of 2009, the Cape Cod Regional Technical High School (CCRTHS) solicited for designers to perform a comprehensive investigation of the existing conditions at Cape Cod Regional Technical High School. In January 2010 the study commenced. The Scope of work defined in the CCRTHS’s request for proposal, included the following: 1. Provide comprehensive field investigation of the existing conditions. 2. Review existing conditions with school maintenance personnel and perform an assessment of the

physical condition of the repairs needed. 3. Prepare a report with written and graphic description and analysis of the current conditions and

issues. Make recommendations for remediation of the conditions/issues, including a prioritization for immediate and long-term action with cost estimates for Repair/Replacement of same, for review by the Cape Cod Regional Technical High School District.

4. Meet with members of the Cape Cod Regional Technical High School District and the Cape Cod Regional Technical High School Committee as required, to present and discuss the report/recommendations, construction documentation work and construction period issues.

Methodology Civitects, along with its MEP-consultant, Garcia Galuska DeSousa, Inc., began a comprehensive field investigation of both the exterior and interior conditions, noting and photo-documenting their observations. As a part of this investigation, Civitects also surveyed for issues with respect to the current Massachusetts State Building Code as well as the Massachusetts Architectural Access Board. At the time of the investigation, Civitects submitted a survey form to the faculty of CCRTHS to better understand user’s issues and needs. Information collected from these surveys can be found in Appendix A. After the initial survey work, Civitects developed recommendations for short term and long term goals for repair and replacement of finishes and systems, by phase, including cost estimates.

3. Existing Conditions Report GENERAL The existing building, is a 3 story, steel joist and masonry framed structure, assumed Building Type 2C. The building measures 521 feet long (at its longest) x 335 feet wide (at its widest) x 56 feet high (at its highest). MEP SYSTEMS Take from GGD reports. BUILDING INGRESS AND EGRESS Former Main Entrance The former main entrance is at the south end of the building, and immediately visible upon entering the school campus. This entrance is via an exterior stair to the second floor mall, an approximately 28’ wide corridor functioning as the main connector. That entrance is no longer used due to the lack of handicapped accessibility and, more recently, concrete degradation. This entrance has the appearance, because of its prominence, of being the main entry to the building. There is no signage in this area to direct the public to the currently used main entrance and as such, causes some confusion.

301. Aerial View of Campus (from Google Earth) Current Main Entrance The currently used main entrance is hidden at the east end of the building. This entrance is set back, deeply flanked approximately 55 feet by Auto Mechanics and approximately 85 feet by Welding; it is difficult for first time visitors to locate. A sign stating main entrance has been placed at the edge of the parking lot to help identify the entrance. (see photo 3x.)The School has indicated that many people try to use the former main entrance on the south side of the building or one of the doors on the first floor level. There is a receptionist’s desk located directly inside the vestibule.

SECURITY Due to the increasing security and safety issues in around the country, faculty expressed concern over the lack of safe spots and the ease with which one might enter the building without being detected. Former Main Entrance Faculty have reported that the doors here stick and do not close properly, allowing people access to the inside. The school has also reported that students occasionally let the public in at this location. Current Main Entrance Faculty have expressed concern about the vulnerability of this entrance due to the very ‘wide street’ corridor it enters into with only the eyes of one receptionist for control.

306. Door to Stair #5, Under Former Main Entr. 307. View of Current Main Entrance from Mall 2060 Other Entrances There is also ready access into the rest of the school from those Shop programs that allow access to the public. These areas include the dental clinic and the childcare center. There is no security control between the inner areas of these programs and the rest of the school. The auto shops, horticulture, construction cluster (plumbing, electrical, grounds, carpentry, hvac) and marine/welding have gated access. The gates are to be locked at all times except during deliveries, and movement of equipment in and out of these areas. However, the security is a concern as the Faculty have reported they are not always locked when they should be. This leaves the man doors at each shop potentially vulnerable to unauthorized people to gain access.

308. Gated Entry 309. Entry to Roots and Roses The Roots and Roses Florist Shop entrance is also of concern to the school. Customers are sometimes permitted into the greenhouse adjacent to Roots and Roses at which point there are no security measures, between the greenhouse and the rest of the school. Also expressed as a concern by the Faculty, is ready access into the greenhouse in warmer weather, through open windows. There are also three first floor egress locations on the west side of the building that are of concern. These locations have access via stairs to the Gymnasium area on the second floor and according to faculty reports, are frequently propped opened and might allow the public unauthorized access into the building.

310. Doors at First Floor, West Elevation 311. Doors at First Floor, West Elevation The Cafeteria Egress Doors at the Commons are routinely locked to prevent the general public from entering in. According to the faculty surveys, the site concerns were minimal. Some faculty expressed concern about accessibility to the lower levels of the school including the athletic fields. It was also expressed that the softball fields could use some work as well as the soccer scoreboard. Better accessibility for septic pumping, standing water and hazardous waste safety were also concerns. EXTERIOR Walls According to the school administration, portions of the building underwent masonry restoration as part of the roof replacement project undertaken in 2005. Work included the removal of existing damaged brick and replacement with similar brick. Additional work included repointing at locations exhibiting significant deterioration. Administration noted that they had pursued having additional masonry restoration performed, however, this did not occur due to a lack of funding. At the time of the project, however, the school purchased an additional xxx bricks for future restoration efforts. These masonry units are currently stored on site. Indicate where restoration was done. In general, the exterior masonry walls are in good condition and the extent of ferrous and biological staining is relatively minor. The exception to this is the north elevation where there are several areas where significant masonry deterioration is occurring. Civitects noted, however, the deterioration of existing masonry joints and sealants as well as spalling is prevalent at all locations. Spalling has been a recurring problem for this building and the cause is likely due to the previous application of a masonry sealer as well as the brick type. While it is not clear what type of sealer was employed for the 2005 restoration work, it is assumed that the product utilized was breathable and that a previously applied sealer is the source for the current spalling concerns. Hairline cracks occurring along exposed brick faces of most elevations points to the fact that the issue of spalling will be an ongoing problem. It appears that this will continue to be a maintenance issue for the school in the near and long term and that the original brick units will require removal and replacement as damage occurs. It is expected that the school’s stockpile of additional bricks will be utilized to replace removed units. Additionally, locations of loose and missing mortar joints, as well as the presence of efflorescence, was recorded. Expansion joint caulking is original in many locations and the caulking is exhibiting signs of deterioration. Re-caulking performed as part of the 2005 masonry restoration work appears to be in good condition. Areas of damaged caulking will require removal and replacement with new caulking and backer rods. Any future masonry restoration efforts should take all of the above issues into account in conjunction with addressing the issue of spalling.

Vandalism to exterior brick masonry enclosed columns immediately outside some of the first floor shops along the north elevation is evident. Damage to brick masonry appears to have been caused by hammers or some other blunt instrument. Caulking at column expansion joints has also been cut creating a considerable gap allowing water to infiltrate the column enclosure.

Windows and Doors: Faculty reported concerns over seals and frames which are allowing cold and water into the building. Window locations include Exercise Room 2002, Classroom 2012b, Graphic Arts RCR 2053, Classroom 303 and Information Technologies 3011. Man Door locations include Classroom 304. Overhead door locations include Auto Mechanics 2135, Horticulture 1113, Outside Storage 1122, and Marine Repair 2120. Windows The existing exterior windows appear to be original to the building. They are a 2” aluminum frame construction, double paned with tinted glazing. The windows are losing efficiency as window seals have begun to fail over the years. Evidence of this may be found at aluminum storefront entrances where sealant is absent and backer rod has been stuffed into gaps surrounding the frame (Photo 318). Based on information received from the school, it is not clear whether any of the perimeter caulking or window glazing contains asbestos as these items have not been tested. Of concern are the locations where window sills are not properly pitched away from the building, thereby prohibiting positive drainage and allowing ponding to occur (Photo 3x). It appears that the combination of sitting water and deteriorated caulking at windows and adjacent masonry joints are the primary contributing causes of moisture infiltration at several window locations.

Roof The original roof construction at the flat roofs, according to the original drawings, was a built-up roof on 1½” rigid insulation on either 1 ½” steel deck, 3” acoustic deck or 4 1/2” concrete deck depending on the location. The drawings indicate a vapor barrier was used. The flat roof was replaced in 2005 with a membrane roof. With the exception of minor leaks occurring at some of the roof seams, the flat roof appears to be in good condition. Evidence of water infiltration may be found at the 3rd floor where water stains on the ceiling are visible, as well as the 2nd floor ceiling, where the penthouse is located directly above. While minor areas of ponding are occurring at the main roof, substantial ponding, however, was noted at the 3rd floor exterior decks located on the north side of the building. The issue of ponding at the deck is due to the lack of sufficient roof slope, thereby preventing positive drainage to the roof drains. The sloped areas of the roof, as well as the elevator hoistway cap, are of a standing seam metal construction (Photo 331). Most of the standing seam metal roofs are exhibiting signs of wear and rust formation. While most of the original perimeter cap flashing was replaced as part of the 2005 project, most of the original curb and masonry flashing elsewhere on the roof remains. The majority of roof drains and strainers, as well as many of the duct and equipment supporting systems, also appear to be original. The removal and replacement of these systems does not seem to have been included as part of the 2005 roof replacement project. As a result, rust has formed on many of these exposed metals causing staining to occur.

333. Rusted Roof Drain Exterior Stairs Several concrete stairs at the north and south elevations are exhibiting significant signs of deterioration with exposed rebar visible in locations. Ferrous staining is evident at the south stair leading to the 2nd floor corridor (Stair No. 12). The cause of this staining is due to moisture infiltrating cracks located along stair risers. Over time, this has lead to the formation of rust which is currently leaching through these cracks. At the base of Stair No. 12 is a terrace consisting of concrete benches and brick pavers arranged in a basket weave pattern over a concrete slab. Paver mortar joints have decayed over the years due to water runoff from the sloped roof above the terrace. Past remediation attempts have consisted of either caulking deteriorated joints or completely removing areas of pavers directly below the sloped roof where the most severe damage has occured. Water runoff from this sloped roof has also led to staining of the vertical brick wall immediately below the roof.

334. Stair No. 12 with ferrous staining 335. Deck located at top landing of Stair No. 13 The concrete risers and treads comprising Stair No. 13, also along the south side of the building, are in fair condition with some areas of crumbling occurring at concrete nosings and treads. The brick sidewalls of this stair are showing considerable signs of decay with spalling and joint deterioration. Additional areas of concern include the exterior deck to the south of the 2nd floor dining commons adjacent to the top landing of Stair No. 13. Here, deterioration of the deck’s existing brick sidewalls and glazed pavers appears to be due to the inadequate pitch to a floor drain and the resultant standing water

13

occurring due to insufficient drainage. Attempts have been made to repair this area by removing some pavers and installing a concrete patch. The most severely damaged stair surveyed is Stair No. 14 which services the library roof deck at the north elevation. Improperly sized steel reinforcement installed at stair nosings, has lead to considerable decay over the years. This stair represents a significant safety hazard and should not be utilized. Of additional concern is the fact that this stair functions as an emergency egress route for library occupants.

336. Stair No. 14 with exposed steel reinforcement 337. Stair No. XX Damaged Treads Exterior Decks The second floor deck adjacent to the Library 2078 is located above the Painting and Decorating Shop 1132. Cracks in the concrete have a potential for leaking. The third floor decks adjacent to the Academic Classrooms are located above Guidance, Graphic Arts, Cosmetology and the Library. Each of these report leaks that come down at the column locations. During periods of rain, water tends to collect on these roofs.

338. Cracks in Concrete at 2nd Floor Library Deck 339. Standing Water at 3rd Floor Roof Deck INTERIOR Similar to the exterior, the interior of the building after 35 years is showing signs of wear and tear. Wall Partitions The original interior partition walls are typically 8” masonry block walls. In some locations such as the mall and the lecture space, fluted CMU units were used. Most of the walls have a special coating, according to the finish schedule in the original set of drawings. Other block walls are simply painted. In general walls

14

and wall finishes are in good condition. Faculty have reported mold and mildew on walls at Horticulture 1113 and water damage has been reported at room 2043 at Guidance. The faculty has also noted dust collecting in the “pourous cement walls” at Classroom 303. Numerous new partitions have been added since the original construction. At the third floor, these appear to be metal and gypsum board or metal wall system partitions. Elsewhere, throughout the school, and particularly at the first floor, wood partition walls appear to have been added.

342. First floor partitions 343. First floor partitions at Hazardous Materials Storage??? Flooring There are several different types of flooring throughout the building. Among the types are concrete slab with hardener, carpeting, quarry tile, and resilient flooring. Floors tend to be worn and in some locations are cracking. The hardener on the concrete floors in the Kitchen and Athletic Locker Rooms and the quarry tile in the Mall show the most evidence of failing. Maintenance has indicated that they try to fill in large cracks with epoxy to prevent them from becoming tripping hazards. The resilient tile at the Dental Classroom 1084 is also cracking. At the third floor, carpeting is old and stained and in Classroom 3016, the carpet no longer lays flat in areas. New athletic flooring was installed at the Gymnasium in 2005 and is in good condition.

According to the staff surveys, there are some panels with water stains and mold on them. Several rooms have missing panels that need to be replaced. Electrical Shop 1163 has a whole in the gypsum ceiling due to a need to gain access to correct a previous leak. In some of the Construction shops, such as Groundskeeping 1073, and HVAC 107, ceilings were partially removed and never finished when overhead doors were replaced. Maintenance indicated that the overhead doors are 10+ years old. Some of the rooms on the second floor underneath the third floor roof decks, have had ceiling tiles removed to gain access to leaks when it rains. These locations include Guidance Office 2043 and Graphic Arts 2053. At the Commons 2068, ceiling panels are stained at the supply grills due to condensation. Also at first floor, in areas where work has been done near overhead doors, ceiling panels have been removed and not replaced. Also, some classrooms such as Culinary Arts RCR 2104, have old ceiling tiles that are dirty and chipped.

HVAC - Heating, Ventilation and Air Conditioning:

Boiler Plant:

The boiler plant consists of (3) three dual fuel cast iron sectional boilers, hot water pumps, accessories and associated control system. The boilers are HB Smith 450 Mils, 21 section boilers with a hot water capacity of 6200 MBH output each. The boilers were installed as part of the original construction project (1975). One of the boilers is not currently in service as it is in need of chamber brick work repairs. All of the boilers appear to have proper safety control systems installed. The two boilers which are in service appear to be in fair condition; however they are nearing the end of their expected service life. The boilers have dual fuel (oil & gas) burners oil. There are (2) two 10,000 gallon above ground fuel oil tanks located outside the mechanical room near the Tri-Gen system enclosure. The fuel oil tanks appear to be in very good condition. The boiler breeching is routed to the outdoors to a free standing steel chimney which was installed in 1975.

The hot water boilers serve a north zone and south zone radiant heating hot water loop and a reheat hot water loop. Each hot water loop is served by a base mounted end suction pump equipped with premium efficiency motors (20 hp) and variable frequency drives (VFDs) with manual change-over valves. There is also a common standby pump (w/o VFD). All of the pumps appear to be original vintage and in good condition; however the pumps have exceed their expected service life.

A ceiling mounted heating and ventilation unit serves the mechanical room to provide heating, ventilation and combustion air for the mechanical room and boiler plant. The unit appears to be original vintage (1975) and in fair condition. During the site visit it was observed that there was excessive vibration from the unit which in turn caused vibration in connected ductwork and piping systems.

Chiller Plant:

The chiller plant consists of a water cooled electric chiller, cooling tower located on grade, condenser water pumps, chilled water pumps associated accessories and controls. The chiller has an approximate capacity of 287 tons, was manufactured by York, was installed in 1988 and appears to be in good condition. New chiller plant controls were installed in the summer of 2009. The cooling tower was installed as part of the Tri-Gen system upgrade project (see below) and appears to be in very good condition. The cooling tower is manufactured by BAC and has capacity control via fan speed VFD control. The primary condenser water and chilled water pumps are installed in the mechanical room and have been retrofitted with premium efficiency motors and variable frequency drives (25 hp each). One of the pumps is a common condenser water/chilled water standby pump (without VFD with manual change-over valves). An inline secondary loop chilled water pump is hung from the ceiling and appears to be in very good condition. There are also two chilled water pumps (3 hp each) which used to serve a secondary chilled water loop which is no longer used. All of the pumps appear to be in good condition; however the primary chilled water and condenser water pumps have exceed their expected service life.

DRAFT



Water Cooled Chiller Cooling Tower Chilled and Condenser Water Pumps Tri-Gen Plant:

The Tri-Gen plant serves a absorption chiller that is located within the same utility room enclosure that houses the Tri-Gen system generator. The absorption chiller has a capacity of 80 tons and is manufactured by Broad. The absorption chiller appears to be in very good condition.

Cape Cod Regional Technical High School Harwich, MA HVAC Existing Conditions Systems Report J#610 004 00.00 L#30215/Page 4/March 1, 2010 Controls:

The building HVAC systems are controlled by a combination direct digital and pneumatic automatic temperature control system. The direct digital control and energy management system is manufactured by Siemens. The front-end workstation and primary control system panels are located in the main mechanical room. The majority of the existing pneumatic control system was manufactured by Powers, and the major components, such as the air compressor and main control panels are also located in the main mechanical room. The pneumatic control system controls the majority of existing air handling unit hot water control valves and air-side dampers, whereas the DDC system controls the boiler and chiller plants as well as newer air handling unit systems. Both control systems appear to be well maintained; however the pneumatic control systems are typically becoming more expensive to maintain.

Air Handling Systems:

Administration:

The administration areas of the building are provided with heating, ventilation and air conditioning primarily from variable volume air handling units which deliver air conditioning through an overhead air distribution system. Exterior offices are also heated by perimeter fin tube radiation. The majority of air distribution devices and baseboard radiation in the administration areas appear to be in good condition. Fin tube radiation enclosures in these areas are generally in fair condition. There are some offices in the administration area which do not have proper zoning control, e.g. an exterior corner office is on the same zone as the interior zone. It is our understanding that some of these offices were part of architectural renovations in which the HVAC system distribution was not properly addressed.

o Technical Studies Director: This office does not have a dedicated VAV zone and does not have a

return air grille; thereby causing temperature control problems in this office.

:

The auditorium and cafeteria is heated, ventilated and air conditioned by an overhead supply air distribution system which is served by an indoor air handling unit. The overhead distribution devices appears to be in fair to poor condition; indicating that the ductwork, registers and diffusers should be cleaned and or replaced in areas. Return air in returned to the air handling unit via one large wall and one high wall return grilles. Exterior walls are heated by fin tube radiation which appears to be in fair condition.

Classrooms:

Exterior Zone Classrooms:

The majority of academic classroom areas are heated, ventilated and air conditioned by wall type classroom unit ventilators. The majority of the unit ventilators have been replaced within the past three years and are therefore in very good condition. Wall type unit ventilators typically are cooling and heating type units manufactured by McQuay Model AAF and have face and bypass and valve control. Ceiling type unit ventilators typically do not have face and bypass controls, but have valve control. Typical Classroom Unit Ventilator at Exterior Wall

Interior Zone Classrooms – Third Floor:

These classroom areas are served by an overhead air distribution system served by air handling units (AHU-19 & 20) and variable air volume terminal boxes. In addition there appear to be some zoning issues in some of the classrooms, facilities has alleviated some over-heating problems by adding flexible transfer ducts.

Computer Classroom – (Room 3016) and IT Technology (Theory):

These classrooms do not appear to have sufficient air conditioning and ventilation for the large number of computers in these areas.

Room 306:

It has been reported that this room experiences temperature control problems in the spring and fall on shoulder season days.

Science Classrooms:

Science classrooms with fume hoods are equipped with fume exhaust systems which appear to be in good condition. We recommend that it is verified that science prep areas are negatively exhausted.

Kitchen:

The kitchen is heated and ventilated by an indoor hot water heating and ventilation unit which appears to be original installed equipment and in fair condition. There are exhaust hoods for the servery, prep area, main cooking area and bakery. There are also dishwasher and pot-scrubbing area exhausts installed. We would recommend that an exhaust be located over the tub sink area. The kitchen office areas adjust to the loading dock are typically cold in the winter heating season.

:

The Auto Repair shop is heated and ventilated by a ceiling mounted heating and ventilation air handling (AH-12) unit. The unit appears to be original installed equipment and in fair to poor condition. The unit appears to provide minimal heating capacity for this area. There are local exhaust air systems installed which also appear to be in fair condition. However, the shop appears to be under positive pressure in relationship to the interior corridor zone. Thereby indicating that either too much outside air or insufficient exhaust air is being delivered to/from the shop.

The Collision Study Shop is heated and ventilated by a ceiling mounted heating and ventilation unit. The air handling unit appears to be original installed equipment and in fair condition. There are some low exhaust air grilles located in the shop; however it appears that additional exhaust grilles should be provided. In addition, paint storage and mixing areas should be provided with dedicated exhaust air systems. There is an existing paint spray booth which is approximately 15 years old. The paint booth appears to be in fair condition; however a new paint booth and ventilation system would provide for improved air quality. In addition the supply and exhaust louvers for the paint spray booth are located adjacent to each other; therefore there is a potential for paint fume exhaust air to be re-entrained to the intake louver.

These shop rooms are served by a ceiling mounted heating and ventilation unit which appears to be original installed equipment and in fair to poor condition. The heating and ventilation unit is located next to the overhead garage door in this shop area. This area is cold during the winter months because the garage door in un-insulated and has some leaks at the door frame. The HVAC and Electrical rooms appear to be more comfortable while the Plumbing shop has experienced warmer room temperatures due to (2) two electrical transformers being located in this shop. The HVAC shop has an energy recovery unit installed for training purposes which also helps to provide improved ventilation to this shop area. There have been reports of unit heaters leaking in the HVAC shop area.

A ceiling mounted heating and ventilation unit and unit heater provide heating and ventilation to this room. The units appear to be in fair condition and original installed equipment. Therefore these units are beyond their expected service life. There have been reports that the unit heater hot water piping has leaked in the past. There are also large gaps at the un-insulated garage doors in this room which causing additional heat loss and allowing untreated air to enter the building when the doors are closed. This condition also causes this room to have a positive pressure in relationship to the adjacent indoor corridor and classroom areas. Therefore, exhaust fumes from this room could travel to adjacent interior areas. A switch-activated, wall mounted exhaust fan was recently installed to help reduce this occurrence.

PLUMBING/FIRE PROTECTION Executive Summary The Cape Cod Regional Technical High School has received minimal maintenance on the plumbing and Fire Protection systems and equipment over its occupied years. Even with adequate maintenance, systems will gradually deteriorate due to scale and poor water conditions. Although most of the systems are working adequately at this time, the major equipment and systems are near the end of their useful life. Along with aging systems, many of the systems are not up to current codes. Fixtures: Fixtures are generally original to the building although some upgrades have been made in the attempt to provide accessible fixtures. The majority of the fixtures do meet the accessibility code as well as the water conservation requirements of the Plumbing Code. The water closets are generally wall hung vitreous china, flush valve type with siphon jet action. Many of the flush valves have been retrofitted with electronic flush valves. The urinals are wall hung vitreous china, flush valve type with blow out action. The lavatories are wall hung vitreous china. The faucets have hot and cold water metering controls. The drinking fountains are generally wall hung vitreous china.

Student showers are generally single temperature controlled by a central thermostatic mixing valve. Trade areas have floor mounted, stainless steel wash basins. The vents from these fixture are not connected to the sanitary vent system. Hair wash sinks are countertop, vitreous china with hot and cold water controls with hand spray. The drains are fitted with lint traps prior to discharging in to the sanitary system.

Cape Cod Regional Technical High School Harwich, MA Plumbing / Fire Protection Existing Conditions Systems Report J#610 004 00.00 L#30227/Page 2/March 1, 2010 Water System: The domestic water service is located within the Boiler Room. The service entering the building is 6 in. which then reduces down to 4 inch. The service is complete with a 4 in. water meter as well as a Watts model #957 backflow preventer. There is an abandoned duplex water booster pump system located adjacent to the water service. The booster pump system has been removed from service for some time. The domestic hot water for the school is supplied from a shell and tube heat exchanger within a 1,600 gallon storage tank which is fed by a tri-gen unit. The system is backed up by the heating boilers. An A.O. Smith boiler has been disconnected from the gas service and is no longer in use. There is a master thermostatic mixing valve on the domestic hot water system prior to being distributed to the building hot water system. The domestic water is being stored and distributed at 138° Fahrenheit. The domestic hot water distributed to the building system should be 120° Fahrenheit. The water connected to the science classrooms does not appear to be protected by a backflow device. There are emergency eyewash’s in the science classrooms however, they are connected to domestic cold water only. Current code requires tepid water to emergency eyewash. There are no emergency showers located in the science classrooms. The kitchen dishwasher and three pot sink are supplied off of the single temperature domestic hot water loop. The water temperature to the dishwasher and three pot sink should be 140 ̊Fahrenheit and the rest of the fixtures in the kitchen requiring hot water should be provided with 120̊ Fahrenheit hot water.

Cape Cod Regional Technical High School Harwich, MA Plumbing / Fire Protection Existing Conditions Systems Report J#610 004 00.00 L#30227/Page 3/March 1, 2010 Drainage System: The sanitary and storm drainage systems are piped with cast iron and copper. The exposed piping which is visible is in good condition. The sanitary drainage system is piped to an on-site sewage disposal system. The science classroom waste and vent system is piped in PVC and discharges to a industrial waste holding tank. The PVC piping material for the system is not a code compliant material in the state of Massachusetts. The kitchen waste and vent system is independent of the sanitary drainage and is piped to an exterior grease trap before it is discharged into the on-site. The automotive shops, marine shops and auto body shops have floor drains that are piped to gas/oil separators which then are believed to be discharged into the on-site sewage disposal system. Current code does not allow garage waste to be discharged to a septic system. The roof is generally flat and is drained by roof drains and a roof drainage system, which exits the building and connects to an on-site infiltration system. Natural Gas System: There is a natural gas service which enters the building through the boiler room. There is high pressure gas provided to the service and is then regulated down to supply the heating boilers, water heater boiler , kitchen equipment and the science classrooms. There is a separate high pressure gas main that supplies the tri-gen unit which utilizes 2 psi pressure. The science classrooms are supplied with natural gas through a master shut-off valve located near the teacher’s station and then piped to the gas turrets. Kitchen: The kitchen equipment is generally original and is in good working order. The cooking equipment is primarily gas fired. The cooking exhaust hoods are fitted with Ansul fire suppression systems which are interconnected to a mechanical gas valve which will close in the event of a fire or discharge of the system. There is no gas solenoid valve connected to the kitchen hood which will not allow gas flow if the hood is not in operation.

Cape Cod Regional Technical High School Harwich, MA Plumbing / Fire Protection Existing Conditions Systems Report J#610 004 00.00 L#30227/Page 4/March 1, 2010 The three pot sink has a point of use grease interceptor which is then piped into the kitchen waste drainage system. The post washer has a point of use interior grease trap which is then piped in to the kitchen waste drainage system. Compressed Air System: There is a central compressor which provides compressed air to all of the technical shops in the school. The compressed air system is piped throughout the school at a constraint pressure and is then regulated down in each shop to the pressure required for that particular trade. Fire Protection: The school is currently protected by a wet sprinkler system. The system consists of four separate fire services. Each fire service supplies a single zone which in turn results in four separate zones of the building. There are four separate fire department connections located at each of the fire services. There is also a fire department connection that supplies a dry standpipe located in the egress stairs in the main part of the building. Standpipes consist of 1 ½” fire department valves located behind access panels in the stairwells. There is no sprinkler coverage in the loading dock which has an overhang and provides for the possible storage of combustibles. The main office and other administrative areas have pendent lights which are suspended less than 18 inches from the finish ceiling. The lights are considered obstructions to the discharge of the sprinkler heads and therefore many areas are not properly protected. The auto body shop has a spray both which has only approximately 12 inches of clear space above in which sprinklers are located. The sprinkler heads located in the spray booth have been covered with plastic bags to prevent the paint spray from getting on it. Recommendations Fixtures: As part of any major renovation or new construction new fixtures shall be installed to meet ADA requirements as well as water conservation requirements of the plumbing code and as required by the MA CHPs or LEED for School. It is recommended that new low flow water closets and urinals be installed to reduce the overall water consumption by 30% or greater.

DRAFT


Cape Cod Regional Technical High School Harwich, MA Plumbing / Fire Protection Existing Conditions Systems Report J#610 004 00.00 L#30227/Page 5/March 1, 2010 It is recommended that new lavatories and low flow, electronic metering faucets be installed to reduce the overall water consumption by 30% or greater. Water System: Much of the domestic water piping system has been replaced throughout the school as part of an ongoing preventive maintenance program therefore as part of any renovation much of the existing system can be utilized. It is recommended to replace the existing domestic hot water storage tank with a new cement lined vertical storage tank with dual heat exchangers. This design would allow for the tri-gen unit to be piped to one of the heat exchangers and either the heating boilers or an back up domestic water boiler to other heat exchanger. This will allow for service of the tri-gen with no change over required to keep the domestic hot water system on line. The domestic hot water system should be fitted with a master thermostatic mixing valve to temper the domestic hot water to the building system to 120° Fahrenheit. A separate supply prior to the mixing valve should supply 140° Fahrenheit water to the three pot sink and the pot washer in the kitchen. It is recommended that hot and cold water supplied to the science classrooms be protected by reduced pressure backflow preventers. There should be emergency showers provided in all science classrooms which have natural gas. The emergency showers and eyewashes shall be supplied with tepid water from an emergency mixing valve. Drainage Systems: The science classroom acid waste and vent system will be replaced using materials approved for use in Massachusetts in a commercial building. As part of a major renovation, we strongly recommend that all of the main under slab drainage piping be documented to verify its condition and the ability to reuse the existing piping. Natural Gas System: The existing gas piping appears to be in good physical condition. As part of any renovation the existing gas piping could reused and reconfigured to meet the requirements of the building as long as the sizing of the system coincides with the new gas load. Kitchen: As part of any renovation, the gas piping to the cooking equipment located under the exhaust hood would need to be modified to include a manual reset gas solenoid valve. The solenoid valve will be interconnected with the exhaust hood which only allows the gas equipment to operate when the hood is in operation.

Cape Cod Regional Technical High School Harwich, MA Plumbing / Fire Protection Existing Conditions Systems Report J#610 004 00.00 L#30227/Page 6/March 1, 2010 The existing point of use grease traps on the pot washer and the three pot sink should be replaced. Grease interceptors will deteriorate over time due to the buildup of grease and other fatty deposits. Compressed Air System: As part of any renovation, the existing central compressor should be replaced with an Energy Star rated compressor to reduce the overall energy consumption for the building. Fire Protection: As part of any renovation, due to the age of the system, we would recommend that all of existing sprinkler heads be replaced with new quick response sprinkler heads. As part of any major renovation the existing pipe schedule system design will need to be reviewed for compliance with the new architectural layout.

ELECTRICAL

Executive Summary

In general, the electrical distribution system is original vintage. The electrical services are more than adequate in capacity but are in poor condition. These services are in need of immediate replacement. Life safety systems such as emergency lighting and exit signs have been modified as the original system has failed where area protection relays were provided. The fire alarm system is not ADA compliant and should be replaced. The life safety systems are in violation of today’s codes and would not be suitable for reuse under a renovation program with the exception of the emergency generator. The best of maintenance programs are intended to make equipment function properly within its expected life span. The emergency lighting and fire alarm systems have exceeded their expected useful life. It is our recommendation, taking into consideration the age and general condition of the existing equipment, that the life safety systems be replaced with new code compliant systems.

Electrical Distribution System

There is one service present at the facility. The service voltage is rated at 277/480V, 3Ø, 4W. The existing main switchboard has a 4000 amp power circuit breaker. The original switchboard is manufactured by Federal Pacific (FPE). The equipment is obsolete and in poor condition. The service equipment does not have adequate space for future expansion. The bus rating of the switchboard should include the Trigen unit and main circuit breaker. It appears that the trip unit of the main circuit breaker was not changed when the Trigen was installed. There is a pad mounted unit substation present and is located outside. The site is on one meter. The service is located adjacent to the boiler room. The service is underground to the building.

Cape Cod Regional Technical High School Harwich, MA Electrical Existing Conditions Systems Report J#610 004 00.00 L#30099/Page 2/February 2, 2010 There are electrical sub-panels located throughout the facility generally in closets. The panels are circuit breaker type but are obsolete. The panels are manufactured by FPE. Some panelboards have live bussing which poses a life safety risk. Electrical Sub-Panels Tri-Gen Service Breaker

The dry type transformers present are standard efficiency Delta-Wye with 480 volt primary and 120/208V secondary. Some of the electric closets do not have adequate ventilation. Lighting panelboards are all 277/480 volt, 3 phase, 4 wire.

Branch Circuits

In the classrooms there is two receptacle on each wall. The quantity of receptacles appears adequate. Receptacles have been added since original construction.

The media center has a computer network present. Power poles have been added to accommodate computer equipment. There is also a computer lab in the media center.

Added receptacles in Science Lab

DRAFT


Cape Cod Regional Technical High School Harwich, MA Electrical Existing Conditions Systems Report J#610 004 00.00 L#30099/Page 3/February 2, 2010 Kitchen receptacles are not ground fault type, NEC 2009 Article 210.8(B)(2) GFCI receptacles are required in kitchens for all 15 and 20 amp 125 volt receptacles. In the science labs, lab benches have duplex 120 volt. The receptacles are GFCI protected. Labels should be installed on all GFCI protected outlets. The lab areas do have emergency power off (EPO) pushbuttons to shut down the power in case of an emergency. The culinary kitchen does not have an EPO pushbutton. The majority of toggle switches present are original and loose in operation.

Interior Lighting System

Lighting in corridors is generally fluorescent surface fixtures which are 1’x4’-2 lamp baffled troffers. The fixtures are a replacement to existing and have T-8 lamps with energy saving electronic ballasts. Cape Light Compact has provided energy incentives which included T-8 lamps and electronic ballasts. Classroom lighting typically consists of fixtures similar to the corridors. The light level appear adequate and have good visual comfort.

Cape Cod Regional Technical High School Harwich, MA Electrical Existing Conditions Systems Report J#610 004 00.00 L#30099/Page 4/February 2, 2010 House lighting in the cafeteria/commons is obtained by the use of incandescent downlights. There is stage lighting fixtures including border lights. There is a fairly new LeHigh dimming system present. The administration/principal areas have pendant fluorescent fixtures which are in good condition.

There is an auditorium dimming system present which is in good condition the keyboard control at the stage manager’s panel is not operational. The library has parabolic (2) lamp fixtures present with T-8 lamps and electronic ballasts. The gymnasium has high output industrial fluorescent fixtures with T5 lamps present. The fixtures are in good condition and were replaced as part of the Cape Light Compact Program.

Gymnasium Lighting

There are vaportight fluorescent fixtures in the locker rooms. The fixtures are in good condition. There is fluorescent industrial lighting present in the shops and mechanical areas. The fixtures are in good condition. Occupancy sensors have been installed in some offices.

Emergency Lighting System

There is an emergency generator present. The generator has been recently replaced and is in good condition. The generator is rated at 275kw, 277/480V, 3 phase. The generator serves emergency lighting, boilers, fire alarm system, heating pumps, kitchen equipment and elevator. The emergency panels are not in a 2 hour rated room as required by Massachusetts Electrical Code. The manufacturer of the generator set is SDMO and was manufactured in France. The generator has a diesel prime mover and is manufactured by John Deere.

DRAFT



Emergency Generator New Automatic Transfer Switch There are area protection relays present in the emergency generator room. The majority of “red” indicating lights are not operational. The system should be upgraded so that the “normally off” emergency lighting scheme is demolished and a new “normal/emergency” lighting scheme is used.

Area Protection Relay Cabinet

The facility is used as a shelter. Therefore the ventilation system for those areas should be connected to emergency power. It was reported that there is only 15% demand load on the generator. It may also be advantageous to change the Trigen setup so that it will run upon power loss if so desired.

Site Lighting System

The exterior lighting at the site consists of pole mounted fixtures and perimeter lighting which lights the area and walkways. It is unclear if the lighting levels are adequate without doing footcandle reading at night.

DRAFT



Fire Alarm System

The fire alarm panel has been replaced approximately 20 years ago. The panel is Faraday Model MPC 2000. The system is not ADA compliant. ADA requires strobes to have a specific candela and decibel rating for a specific room or space configuration. In addition, a voice evacuation system is required throughout “E” use groups, per the Seventh Edition of the Massachusetts State Building Code 780 CMR Chapter 9 907.2.3. The coverage of fire alarm devices appears adequate. Heat detectors are present in some rooms. The Massachusetts State Building Code Chapter 9 requires all rooms or spaces to be provided with automatic alarm devices in non-sprinklered buildings. The spacing of devices must comply with NFPA 72. The building appears to be 100% sprinklered. The present system is above code requirements but is obsolete. Voice Evac. Control Panel in Commons/Cafeteria Non ADA Fire Alarm Horn/Strobe Appliance

Cape Cod Regional Technical High School Harwich, MA Electrical Existing Conditions Systems Report J#610 004 00.00 L#30099/Page 7/February 2, 2010 Classrooms do not have audio/visual appliances present. There are magnetic hold open devices at stair door but pose a tripping hazard. The kitchen hood does have an ansul system and is connected to the fire alarm system. There is a voice evacuation system for the commons room/cafeteria. The main fire alarm control panel is interlocked with the common control panel for simultaneous notification of either system.

Security System/Miscellaneous

The security system is present throughout the facility. Motion sensors are located in the corridors and perimeter rooms. There is a Closed Circuit TV system present with network storage appliance. The system appears operating in a satisfactory manner. There is access control on the exterior doors but is not of the proximity card or key fob type. There is a lightning protection system present but rooftop exhaust fans do not have air terminals installed.

Alternative Energy

There is a small PV system present in Science Lab Room 320. The System appears to be for educational purposes and appears to be rated at 2.5kw sunny boy inverter present. There is also a data acquisition present.

Recommendations

Electrical Distribution System: New construction service rating are generally designed for a demand load of 10 watts/s.f. The existing building is approximately 214,000 sq./ft. It is recommended that a new service rated at 3000 amps, 277/480 volt, 3Ø, 4 wire be installed. In addition, subpanels and feeders should be replaced. The existing peak demand has not exceeded 606kva or 729 amperes. Typically the demand is approximately 33% of the main switch size. Interior Lighting System: New lighting has been installed throughout the facility and is very energy efficient already. It is recommended that lighting controls such as daylighting and occupancy sensors be provided.

Cape Cod Regional Technical High School Harwich, MA Electrical Existing Conditions Systems Report J#610 004 00.00 L#30099/Page 8/February 2, 2010 Emergency Lighting System The existing emergency generator can remain but new circuits and distribution should be installed to serve all egress areas such as corridors, intervening spaces, toilets, and above exterior doors. The emergency distribution system should be included to expand ventilation and power to areas designated as a shelter. Site Lighting System: New “LED” fixtures for area lighting should be installed for energy conservation. Pole mounted fixtures should be provided in parking area to maintain minimum light of 0.5-1.0 footcandles. The “LED” fixtures can reduce the energy consumption by 50%. Wiring Devices: Each classroom should have a minimum of (2) duplex receptacles per wall and (2) double duplex receptacles at classroom computer workstations. Art classrooms should have a minimum of (4) duplex receptacles per wall, (2) double duplex receptacles at classrooms computer workstations and dedicated outlets for equipment. The majority of classrooms have adequate receptacles. The issue is separation of loads and neutral conductors. Fire Alarm System: The fire alarm system should be replaced. The new system requires voice evacuation and audio/visual devices in all classrooms. DRAFT

6. Recommendations MEP/FP The area of biggest concern to the school, is the MEP/FP systems. Although some improvements have been made over the years, many of the original MEP/FP components are still in place and after 35 years are nearing the end of their serviceable life. Add recommendations from GGD ARCHITECTURAL In addition to the updating of the MEP systems, due to the building’s age, the exterior of the building and the interior finishes also need to be modified and updated. BUILDING INGRESS/EGRESS As the General Public enters the site, they see the former Main Entrance before they see the current Main Entrance. Signage should be placed on the exterior of the building to direct people to the current main entrance. This should help alleviate the number of people trying to gain access to the building from the former main entrance. Egress A few spaces at the third floor level, have egress only through other spaces. If these spaces, are not accessory to the rooms being served, they must have their own means of egress. Reconfigure any non accessory spaces so that they have egress directly to corridors and not through other spaces. SECURITY Exterior Egress In order to secure the building from unwanted visitors, the school should consider replacing all the exterior door hardware. Some exterior doorways are on a smart reader systems but not all doors. New hardware would allow the school the option of prohibiting access to all doorways except the main entrance. This will force people to use the current Main Entrance and allow the school to see who is entering the building. The main entrance doors can be unlocked in the morning before school for faculty and staff to arrive. Once school has started for the day, these doors can be locked and operated on a buzzer system. Any students arriving late or any visitors would have to be buzzed into the building. The buzzer could be located at the reception desk right inside the main entrance doors or at the administration office. Security cameras should be placed above the doors to give a clearer picture of who is being buzzed in. Other doors with high public use, such as the door used by the Childhood Development Shop to allow parents to drop off children and the vestibule door to the Dental Clinic and Health Technology Shops could also be equipped with security cameras and buzzed entrances. Depending on the hardware system selected, the school would have the option of giving faculty id cards, and possibly the students too, that would activate the electronic strike on the exterior doors which would disable the lock temporarily on the doors and allow entrance. This would also be useful for the gymnasium teachers to take students in and out of the building for outside activities. The locks at the gates to the construction shop loading areas could be electrified. Entry could be allowed via a card reader, a digital keypad or remote control. Only those with allowed access either by the use of a card or a key code would be able to gain access into the shop loading areas, all others would have to report to the Main Entrance to ask for permission first. Interior Egress Due to the increased needs of security in schools, new hardware has been developed that allows teachers the ability to lock their classrooms from the inside of the classroom. This would protect teachers

2

and students from any potential hazard in the hallway by eliminating the need to lock the door from the hallway side. The hardware allows the classroom to be locked on both the inside and the outside. If a determination is made by the school to limit access of students to certain rooms within the building, the students can also be given an ID card that allows them access to certain areas, such as the lavatories and the library. Some of these types of hardware devices can be equipped with an audit trail capability that would allow the school to retrieve information as to who entered a particular room at a particular time. It is also recommended that the receptionist desk located at Mall 2060 adjacent to Vestibule 2129 be enclosed with bulletproof glass, similar to that used for protecting bank tellers. This would give the receptionist added security protection as well as thermal protection from the doors being opened at the Vestibule. EXTERIOR Walls The masonry exterior of the building is starting to show wear and tear and some failure due to its age. The condition of the existing masonry ranges from poor to good condition. The masonry in poor condition is mostly caused by spalling. The spalling is mainly on the North Elevation with some smaller areas on the East and South Elevations. (See Drawings A4.1 and A4.2) The spalling masonry should be removed and replaced with new to match existing. Other areas of brick in poor condition are the masonry enclosed columns, mostly on the North Elevation, with an additional location on the South Elevation. The masonry and some of the corresponding column expansion joints at these locations needs to be replaced where damaged. The bricks on the West and South Elevations are in good condition. However the masonry joints are cracking or missing is some areas and need to be repointed. The East and South Elevations have areas where the masonry has ferrous staining and/or the presence of biological matter. These areas need to be cleaned. Windows and Doors The exterior windows should be replaced. We recommend that all the windows be replaced at the same time. Those windows that have not already failed are likely to fail in the future due to age and failing window caulking. Due to the ponding at window sills, it is recommended that the sills be replaced with ones that are slanted to provide positive drainage. Original passage Doors at the various Exits should continue to be replaced overtime with insulated doors. Joints at overhead doors should be replaced to cut down on air leaks. Ceilings at overhead doors could also finished to cut down on drafts. ADD Skylights at Third Floor for light and ventilation into classrooms that have none???? Roof Although the flat roofs are in generally good condition, further investigation is needed at the roof level to determine the cause of the leaks at the second and third floors. The 3rd floor deck roofing should be replaced in the future with a new membrane roof with tapered insulation. The existing metal seam sloped roofs should be replaced in the future as they are showing wear and rust formation. Replace flashing and equipment. Exterior Stairs The concrete stairs need repair work where rebar is exposed and treads are damaged and crumbling. Concrete at damaged risers and treads should be removed to ensure a solid substrate underneath.

3

Exposed rebar should scraped and wire brushed to remove all rust. The rebar should then be treated with an epoxy-modified cementitious bonding and anti-corrosion agent. A concrete patching mortar should be used to recreate risers. The patching mortar should be topped with cementitious coating and topcoat. New aluminum nosings should also be installed.

INTERIOR Wall Partitions On the first floor, the faculty has indicated that the movable partitions between Room 1116 and Room 1118 and between Room 1117 and Room 1118 remain in a fixed position and that sound transmission between classrooms is a problem. Due to the fact that the building is considered a 2c building construction type, it is suggested permanent walls of either masonry or steel studs be used to permanently divide these classrooms. A second location on the first floor is between Welding 1061 and Electric Shop 1163. This also could become a permanent wall with a lockable door to provide access between the two spaces. Science Labs 1137 and 1140 have also reported sound transmission at their movable partitions. It is suggested that these movable partitions be replaced with partitions with an acoustic sound transmission class rating. At wall partitions affected by sound transmission, an additional layer of gypsum wall board can be installed to lower the sound transmission. Insulation can also be added above ceilings to mitigate sound transmission. Flooring Floors that are original to the building or are worn or cracking should be replaced, particularly in areas where flooring is breaking up or carpet has become a tripping hazard. Due to the age of the building, a Hazardous Materials Consultant should evaluate the different flooring materials for hazardous materials, ie mastic at the carpeting, asbestos at resilient floor tile, etc prior to having the flooring material removed. After flooring removal, all substrates should be checked for areas needing repair, ie cracks in concrete floor slabs. Leveling compounds should be installed under flooring materials to provide a sound substrate. We recommend the following flooring materials:

1. Existing Concrete floor slab to remain. Patch and repair any cracks and deteriorating concrete. Locations: Electrical Shop, Plumbing and Heating Shop, HVAC shop, Carpentry Shop, Auto Collision Shop, Horticulture Shop, Auto Tech Shop, Marine Services Shop, Metal Fab & Welding Shop.

2. Resilient Flooring: High traffic areas such as hallways; Classrooms; and Cosmetology Shop, Culinary Arts Shop, Health Tech Shop, Dental Assisting Shop, Early Childhood Development Shop; Information Technology Shop and Graphic Arts Shop; Toilet Rooms.

3. Quarry Tile: Mall, Commons, and Culinary Shop. 4. Carpeting: Administration; Guidance; Library; Lecture Hall; and Classrooms as an alternative to

Resilient flooring. 5. Poured Epoxy Floors: Locker Rooms; as an alternative to Quarry tile at the Culinary Shop.

Ceilings Acoustic Ceiling panels are needed where panels are missing or stained due to leaks. Before the panels are replaced the source of the leaks should be modified and remediated. Gypsum Ceilings Stairs The stairs between levels are of steel pan construction. Stair treads with cracked or deteriorating concrete should be replaced. Areas where stairwells are also being used for storage, should have the stored items removed as storing items in stairwells does not meet code.

Accessibility The two ramps at the waiting area at Guidance should be reconfigured. The existing change in elevation is 4”. A ramp of four feet in length is required. There appears to be enough room between the door and the wall to allow for a five foot landing at the top and bottom of each of the ramps and the required four feet of ramp length. Another option would be to eliminate the platform and bring the waiting area down to the same level as the rest of the guidance office. A ramp to replace the stairs between the Greenhouse and Roots and Roses is not feasible as is would require a run of over 30 feet. A wheelchair lift at this stair location could meet the accessibility requirements. Doors should be re-hung where possible to provide AAB clearances. Eighteen inches clear are required at the pull side of the door and twelve inches are required at the push side of the door. See Section 5. Codes and Standards. At some locations, simply switching the hinge and strike sides of the doors will accommodate the required minimum clearances. Door hardware should be replaced to meet AAB requirements. This can be done in conjunction with replacing hardware for security reasons. Hardware should have lever-operated mechanisms, push-type mechanisms, or U-shaped handles that are capable of being opened with one hand. Doors to areas such as loading platforms, boiler rooms and electrical equipment rooms shall have a roughened surface to provide tactile warning to persons with visual handicaps. When seating is replaced at the Large Group Learning Center Room 321 accommodations must be made for handicapped seating with required area dimensions. For a seating area having between 51 and 300 fixed seats, 4 wheelchair spaces must be provide. If the seating is less than 150, the wheelchair spaces can be accommodated in one area. For assembly areas supporting more than 50 seats, a permanent installed assistive listening system is required. Cabinetry and Built-In Furnishings Lockers Existing personal student lockers are old and tired and should be replaced with new wider lockers offering more storage space. Existing locker room lockers are also old and tired and should be replaced with new wider lockers. Storage/Shelving Additional storage and shelving should be added within classrooms and shop spaces. Surveys should be conducted with the individual users of the spaces to determine what their storage needs are. Large Group Learning Center Seating at the large group learning center should be replaced. Layout should include provisions for wheelchair spacing that meets current ADA and AAB guidelines. Bathrooms The school is encouraged to continue their use of waterless urinals and new hand blow dryers to reduce their utility consumption. Each new bathroom should include, per code, a minimum of one handicapped accessible toilet and one handicapped accessible sink.
