A. PREFACE

This study was prepared for the Office of Planning Design and Construction of the Division of Capital Asset Management and Maintenance, Commonwealth of Massachusetts, in accordance with Mas-sachusetts General Laws Chapter 7C, Section 59. It is intended to investigate agency capital needs, evaluate alternatives, and recommend a solution that corresponds to the current needs for the Department of Unemployment Assistance in Brockton.

The study provides a clear and detailed frame of reference for the design and implementation pro-cess and recommends a solution that can be accomplished within the appropriation or authorization for that project. It includes a space program which reflects the user agency’s needs a description of the project requirements, an accurate estimate of capital costs, and an implementation schedule.

Conceptual building designs, where included, are not intended to constrain the final design, but rather to illustrate functional relationships, demonstrate the practical operation of design criteria and conformance with applicable codes and standards, and serve as the basis for developing an accurate cost estimate.

Before DCAMM can enter into a contract for final design services, this study must be certified by the Commissioner of DCAMM. Thereafter no substantial changes can be made to the extents of improve-ments during the implementation process. In subsequent phases, the gross square footage may not change by more than 10% of the number specified in the study or the study will need to be re-certi-fied.






PROJECT SUMMARY

Program Description: New infill construction of an office facility to house the Department of Unem-ployment Assistance to be located at 226 Main Street, Brockton

Total Project Cost: $23,000,000

Estimated Construction Cost: $17,144,804

Building Gross Square Footage: 31,742 GSF

Feasibility Study Process

The goal of this project was to determine the facilities necessary to accommodate the Department of Unemployment Assistance (DUA) at a state-owned site in downtown Brockton. DUA manages the Unemployment Insurance (UI) program, which provides temporary income to Massachusetts workers who are “unemployed through no fault of their own / able to work / available for work and looking for a job”.

This document contains finalized programming information, an investigation into different alterna-tives to meet the program requirements, an existing conditions analysis, and preliminary proposed schedule.

DUA’s program is comprised of two main elements. The first is referred to as the Call Center, which includes both the Claims and Adjudication Departments. Staff in these areas handle calls from people who have recently lost their jobs through layoffs or other means of termination. They assist claimants with the Unemployment Insurance application process and employers with contributions and wage records. The second is the Hearings Department, where cases are heard with legal repre-sentation present. Claimants who are denied benefits can request a hearing to appeal the decision.

Two locations in downtown Brockton were originally considered for DUA functions: their exist-ing building at 36 Main Street and an alternate site at 226 Main Street, which had previously been acquired by DCAMM to house a collaborative academic project. The building at 226 Main has been sitting vacant for a number of years. For the purpose of this analysis the site will be presumed to be delivered cleared and ready for construction.


After exploring multiple options (found in the Appendix of this report), the team developed an option that involved the construction of a new building for DUA on the site in a three-story configu-ration. Programmatic Distribution is as follows:

Basement Level (Partial): 3,000 GSF Electrical / Fire Protection

Level 1: 9,750 GSF Lobby/Reception/Waiting; Conference/Training; Hearings

Level 2: 9,750 GSF Claims/Adjudication (Call Center)

Level 3: 8,112 GSF Seasonal; Break Room; Administrative; Flexible Meeting

Level 4: 2,850 GSF Enclosed Mechanical Penthouse

TOTAL GSF: 31,742 GSF

COST This project has a total project cost of $23,000,000. The cost model for the Consensus Solution is on target with an estimated construction cost of $17,144,804. This assumes a CM at Risk project delivery method. The detailed estimate is included in Section H of this report.

SCHEDULE

The schedule as proposed has a duration of seven months to complete a Certifiable Building Study (including Schematic Design) followed by an eight month period for Design Development and Con-struction Documents. Construction is anticipated to take eighteen months.



C. BUILDING PROGRAM


C. BUILDING PROGRAM

INTRODUCTION

The Department of Unemployment Assistance (DUA) in Brockton is composed of two primary components, the Call Center and Hearings. The Call Center is further broken down into two departments, Claims and Ad-judication. In addition, there are Administrative Offices, Shared Spaces, and Critical infrastructural compo-nents to consider.

DUA employs both permanent and seasonal employees, the latter of which work at times when unemploy-ment spikes, typically around the winter holidays and in the in the summer. In addition, spare desks must be maintained for times when there are larger shifts in unemployment that may last for a year or more. These are referred to as Flexible desks.

The PROGRAM TABULATION at right shows both the existing spaces housed at 36 Main Street and the Right Sized/Projected needs moving forward. The following pages provide further descriptions of program ele-ments and block diagrams indicating relative sizing and spatial relationships.

C. BUILDING PROGRAM

EXISTING PROGRAM DESCRIPTIONS

ADMINISTRATION The Administration space DUA’s only public facing function and it consists of a Reception Desk and a Waiting Area. The Reception Desk is staffed by one of the three Office Support staff from Hear-ings. While th Reception Desk currently houses Records Storage, it is preferable that this function be located to a closed, locked room.

Also included in the Administrative Space are three (3) Director’s Offices which need to be large enough to accommodate small meetings.

Additionally, three (3) Flexible Meeting Rooms which are unassigned serve as temporary visitor offices, small meeting rooms, or remote hearings spaces. Because of these functions, these meeting rooms are to contain high levels of technology.

CLAIMS The Claims Department currently consists of twenty-eight (28) cubicles that are in use and an addi-tional ten (10) that are unoccupied. All of these cubicles are to be retained for future use. Existing cubicle sizes vary but are approximately 6’X8’. This is more space than is needed, especially with the elimination of a printer at each desk. Future cubicles are to b 6’X6’ standard. Cubicle walls are to be 50” tall.

There are four Claims Managers distributed throughout the Claims Department. Managers require closed offices with a pair of guest chairs.

There is currently a “Huddle Space” in the Claims Department. This space is for frequent and short meetings of approximately 15 employees at a time and must remain unless a conference room can be located near by to serve this function.

ADJUDICATION

The Adjudication Department currently consists of twenty-two (22) cubicles that are in use and one (1) that is unoccupied. All of these cubicles are to be retained for future use. All future cubicles are to be 6’X6’ standard, with cubicle walls at 50” tall. In addition, Adjudication cubicles are to have 12” glass extension panels mounted to the top of the cubicle walls for acoustic privacy.

There are four supervisor spaces in the Adjudication Department. These are not closed offices but consist of 6’X6’ cubicles with added glass partitions. The proposed program calls for a single closed meeting room to accommodate up to (4) people to facilitate private conversations between supervi-sors and staff.

There is currently a “Huddle Space” in the Adjudication Department. This space is for frequent and short meetings of approximately 15 employees at a time. This function must remain but can occur in a conference room rather than a dedicated space.


SEASONAL Claims and Adjudication

The Seasonal area currently houses seventeen (17) occupied desks that are shared between Claims and Adjudication. That number should increase to twenty to twenty-five (20-25) in the future de-sign to allow for greater flexibility. Seasonal desks are used for almost ten months a year so cannot be substituted for other programs at certain times - this must have dedicated space. Because these are not permanent workstations, however, there the possibility of using a desking system that is less cubicle-like, and inherently more flexible.

There is one Program Coordinator for the Seasonal staff who requires a closed office with guest chairs. This individual oversees both the Claims and Adjudication portions of the Seasonal staff.All seasonal staff should remain together in the same space if possible, and should be separate from the full time Call Center staff.

FLEXIBLE

The Call Center currently maintains twenty-eight (28) empty seats that can be filled on a more per-manent basis with shifts in the economy. Projections indicate that all of these seats should remain for future use, and that all should be 6’X6’ cubicles to which glass extension panels can be added at a later time if they will serve Adjudicators.

HEARINGS

The Hearings Department Consists of five (5) Hearings Offices, one (1) Hearings Manager, and three (3) Office Support workstations. Additional versions of this program and layout focusing on flexible workspace were discussed and dismissed; the current layout projects well for future use.

The layout of these offices is important to the way hearings are conducted. New furniture should replicate this layout.

SHARED

Program projections have identified the need for three large Shared Spaces in the future, each being approximately 500SF. The Conference Room should seat at least sixteen (16) and needs to have ad-jacency to both Claims and Adjudication if it is to be used as huddle space for both of those groups.

The Training Room should also seat sixteen (16) with flexible furniture that can be re-arranged if necessary. The training room will utilize laptops, making an adjacent Laptop Storage room nec-essary. If possible, having a movable partition between the Conference Room and Training Room would provide some added flexibility for occasional larger events.

The third large space is the Break Room. Seating for at least sixteen (16) is to be provided, as well as countertop, sink, refrigerator, microwave, two (2) vending machines, and two (2) trash containers. Details of the Break Room will need to be discussed further in design.

A centrally located Server Room will serve all departments. Art Engineering also recommends Tele-com closets at each floor to help with distribution and maintenance.

A centralized Copy/Mail area, office supply Storage Room, and Kitchenette are required for the Call Center and Hearings. Claims and Adjudication can share these amenities if they are sized according-ly. Hearings needs a separate space. Kitchenettes will include a piped coffee machine, microwave, under counter refrigerator, and sink (no disposal).

ADDITIONAL PROGRAM NOTES

IMPACT OF TECHNOLOGY ON PROGRAM

There will be opportunities to introduce new technology into the Call Center portion of the program. As previously mentioned, the amount of equipment required at each cubicle is changing, resulting in an acceptable reduction in size and quantity. Printers, for instance, will not be located at each workstation; instead, centralized print stations will be utilized.

At some point in the future it may be possible for the Adjudicators to work remotely by logging in to a cloud based system, however, this technology is currently multiple years away.

It was determined that if it becomes possible to reduce some on-site staff due to this advancing technology, any reductions in program space would be offset by the possibility of consolidation of multiple state-wide call centers to this location. For this reason, the design team will not explore a reduced program footprint moving forward.

DESKING / HOTELING

As discussed with regard to the Seasonal staff area above, there is the possibility of utilizing a less permanent desking solution than cubicles. The general consensus is that each desk must be large enough to house a staff member as well as an instructor for an extended period of time, and must also have a certain degree of acoustic privacy. An open benching strategy would not work. On the next page there are a series of furniture images to be discussed as possible solutions during the next phase of study. Additionally, the design team will explore the use of sit-to-stand desks, also pictured.

Update: upon further discussion DUA believes that individual cubicles similar to those used in the Claims Department are the most appropriate seating strategy for Seasonal employees. Even though Seasonal employees are temporary, their desks should not intentionally reflect this difference from the Call Center employees. The issue should only be revisited if space constraints demand a different seating approach in the design phase.

D. FEASIBILITY ANALYSIS



SITE PLAN

The property at 226 Main Street in Brockton is currently occupied by a building with a footprint of approxi-mately 85’ by 116’. The feasibility study planning strategy found on the following pages shows that while this size footprint is not necessary to fit the program from a total square footage standpoint, locating the entire Call Center on one floor (a priority for DUA in terms of functionality) results in a building with dimensions very similar to those of the existing building. This footprint completely fills out the build-able area of the site.

The primary public entrance is located on the West (Main Street) facade. This public entrance is currently designed by a notch in the facade creating a covered area. It is currently not monumental in nature, and will need to be explored further in deign as DUA would like the entrance to be very clear to visitors.

At the rear (East) facade the building front a green space covered in part with lawn and in part with a paved terrace, both of which are scattered with trees. This is City property, so any routes through the green space to the employee entrance on this facade will need to be coordinated with them.

SITE PLAN



PREFERRED ALTERNATIVE SUMMARY

The design team undertook a planning effort as part of the Feasibility Analysis, developing four unique strategies for DCAMM and DUA review. This planning effort can be found in the Appendix. These planning iterations led to the development of some critical strategies, below, and ultimately to the preferred Feasibility Planning Strategy found on the following pages.

1. Call Center is to be located completely at one floor. Early schemes had the two components of the Call Center, Claims and Adjudication, split between floors to minimize the overall building footprint. It was determined that locating all of these desks at one floor is preferred, and possible from a planning standpoint if the building footprint is maximized to cover the entire site. This single move has a dramatic effect on the overall size of the building, leading to additional unassigned program space. The Call Center should not be located at street level, and should be secure on an upper floor due to the sensitive employment information that is exchange din this space.

2. Day One Cell Center staffing. The total number of Call Center cubicles (96) includes (55) currently occu-pied desks and (41) currently unoccupied. It is possible that the economy will dictate more employees be hired between now and when this building is completed, however if desks remain open DUA will be able to think about alternate program elements with in the Call Center. Huddle-spaces are suggested on the plans, with could easily be defined by ceiling treatment or furniture. This temporary space will need to be studied further in design.

3. Unassigned program space. The footprint required to accommodate all of the Call Center at the second floor results in unassigned program space at both the first and third floors. Appropriate program infill is considered to be shared meeting and conference space (see further description below.) At the third floor the appropriate program infill is considered to be additional call center growth space. Unassigned program space is to be studied further during the Certifiable Building Study.

4. Shared program space located at first floor. These program elements include Training Room, Conference Room, and various smaller meeting spaces. It was determined during the planning exercise that these spaces are best located at the street level. This position in the building could potentially facilitate usage by other state entities, and are the least sensitive from a security standpoint.

5. Hearings department located at the first floor. The Hearings department is the only portion of DUA that interfaces with the public. As such it makes the most sense to locate this program at street level. Given that Hearings cases can become contentious, Review Examiner offices should have windows and panic buttons. In addition the Hearings department should have access to staff only bathrooms so review examiners do not need to use public restrooms and risk running into an upset claimant

6. Employee environmental experience to be elevated. Due to the depth of the floor plate there is both a need and an opportunity to deliver natural light to the middle of the plan, achieved in the preferred alter-native by leans of a light monitor. An open-to-below space at the third floor will allow natural light to spill down to the Call Center at the second floor. Large windows at both front (west) and rear (east) facades will also help to get natural light deeper into the plan as well as affording views to the exterior. An exterior terrace/roof garden has been included at the third floor to give employees a place to spend their break time, located at the rear facade, overlooking an adjacent green space.

7. The building systems will reside at the basement and roof levels, with chases running along the north and south party walls to feed the intermediate floors. The basement has a very small footprint relative to the floors above which will result in a strategy where the existing basement on site will need to be infilled. See building systems narratives in this report for additional details.

G. ITEMS FOR FURTHER STUDY


G. ITEMS FOR FURTHER STUDY

The following issues are to be studied further in the Certifiable Building Study.

GENERAL:

1. Refinement of sustainable design goals. Preliminary strategies are indicated in Section D and within MEP narratives. Facade treatment and envelope to be studied to generate the most efficient building for Brockton’s climate. In particular a pho-to-voltaic array at the high roof will be studied. Utility companies brought into design process to pursue rebate possibilities.

2. Investigate Transformative Development initiative (TDI) for growth and develop-ment; potential impact on design. Brockton is designated as a Gateway City and 226 Main Street lies on the edge of the Downtown Gateway District.

INTERIOR:

1. Refinement of all building systems strategies.

2. Refinement of Security approach. Preliminary strategy outlined in Electrical/Tele-com narrative. Types of devices and locations to be discussed with DUA facilities to ensure proper security measures are taken.

3. Degree to which spaces remain open or are partitioned for acoustic and visual pri-vacy. This applies to Cell Center and shared Meeting Rooms in particular.

4. Primary entrance at first floor on Main Street side to be studied further, DUA has expressed a desire for this entrance to be more visible than their current building en-trance does. Location could shift based on site strategy as well.

5. Unassigned program space at third floor - how will this space be used, for more closed meeting rooms or perhaps as open work space? If just 10 desks can shift up from Call Center at second floor the floor plate can become narrower, which could have a significant effect on total building area - approx 3,000SF. Third floor plan currently shows 10 desks at this location for reference.

6. Configuration of shared spaces, in particular the Conference and Training Room at the first floor. How will these rooms be used on a daily basis, for events, and for visi-tors? Furniture and partition configuration will need to reflect usage.

7. Break Room at third floor requires study of furniture types for varied ways of utiliz-ing the space.

8. Study the usage of space that may not be used for cubicles day-one due to the cur-rent state of the economy. Temporary huddle-spaces that could also be used as break rooms are one consideration.


EXTERIOR:

1. Extents of roof monitor, which is currently quite large. Sun studies will determine the depth that sunlight penetrates into the floor plan, the roof monitor may be able to be decreased in size accordingly.

2. Extents of mechanical penthouse. Further investigation will help decide whether it will be a visible element on the Main Street facade or pushed back to minimize visibil-ity as much as possible. Also investigate whether the mechanical equipment can be relocated to the interior (third floor), eliminating the need for a penthouse and elevator to the roof level.

3. Exterior terrace at the third floor - how and when will this space be used. Materials and details will be designed according to function. Investigate plantings at this terrace as well.

4. Exterior aesthetic to be studied in greater detail including massing, elevation, and material strategies. Diagrams in Section D begin to address some of the many ways this building can begin to address the public and built context.

5. Verify that existing historic facade is not to be retained in any capacity, not even a modified version of the current elevation.

6. Study the nature of the green space at the rear (East) of 226 Main Street abutting municipal parking. Determine whether this property (owned by the City of Brockton) can or should be improved as a part of this project. Understanding the value and long terms plans for the 1 story building directly to the South of 226 Main street could also influence design. If this building were to be demolished and the space be converted to park space, for instance, it would open up another public facade for 226 Main Street and result in a reconfiguration of interior planning.

7. Research various City of Brockton downtown redevelopment Initiatives to deter-mine impact on facades and streetscapes.

8. Investigate context of this neighborhood in Brockton, known as the Corcoran Sub District, which includes Salisbury Greenway Park and the partially underground Salis-bury River. Connections from 226 Main to this public outdoor space behind the build-ing could be promoted.

Introduction & Project Description Jones Architecture has retained Code Red Consultants to provide fire protection, life safety and accessibility code consulting services for the preliminary planning study associated with the Division of Unemployment Assistance office in Brockton, Massachusetts.

The Division of Unemployment Assistance (DUA) is currently located at 36 Main Street in Brocton, Massachusetts. The DUA occupies the entire building which consists of 4-stories above grade and a basement level.

The preliminary planning study includes the review of both 36 Main Street and a second building located in Brockton, MA at 226 Main Street. Work to 36 Main Street would include a building renovation while work at 226 Main Street includes the construction of a new building.

The following code report addresses the new construction provisions associated with the 226 Main Street site. Note that the code approach assumes that both options will have a roof height of less than 70 feet above the average grade plane and not classified as a high-rise building.

Building / Fire Protection / Life Safety Code Approach The following describes the basic building code compliance approach for the project.

3.1 Use and Occupancy Classifications

The following table lists the primary occupancies within the building:

Primary Occupancy Groups (780 CMR 301)

Description Classification

Meeting Spaces > 49 occ. Group A-3

Office Space

Meeting Space ≤ 49 occ. Group B

Storage/MEP Group S-2

The building is classified as a non-separated mixed use and does not require occupancy separations (780 CMR 508.3.3).

3.2 Construction Type

The proposed building consists of 3-stories above grade, with a basement. The maximum footprint area is 9,750 SF and the aggregate building area is 34,000 SF.

Following a non-separated mixed use, Type IIIB construction permits Group A-3, B and S-2 uses to be a maximum of 3-stories in height with a maximum footprint area of 28,500 square feet and an aggregate building area of 85,500 square feet. Note these allowances assume automatic sprinkler increases but do not assume any area increases for frontage.

Type IIIB construction is acceptable for the proposed building for the primary occupancy groups present, Group A, B and S-2.

Note that the penthouse must comply with 780 CMR 1510. Penthouses are limited to MEP uses only and must not exceed one-third the area of the supporting roof.



Page 6

Fire Resistance Rating of Building Elements

Building Element Type IIIB Construction

Primary structural frame 0 Hour

Exterior bearing walls 0 Hour

Interior bearing walls 0 Hour

Nonbearing exterior walls 0 Hour

(See Section 3.3)

Floor construction and secondary members 0 Hour

Roof construction and secondary members 0 Hour

3.3 Exterior Walls

The rating and opening limitations for new nonbearing exterior walls are based on the fire separation distance for each wall. Fire separation distance is defined as the distance measured from the building face to the closest interior lot line, the centerline of a street, alley, or public way, or to an imaginary lot line between two building (780 CMR 202). The distance is required to be measured at right angles from the face of the wall. The table below indicates the fire-resistance ratings and opening limitations required for the exterior walls based on fire separation distance (780 CMR 602 & 705.8).

Nonbearing Exterior Walls – Type IIIB Construction

Fire Separation Distance (ft)

Rating

Groups A, B & S-2

Allowable Area

0 ≤ X < 3 1 Hour Not Permitted

3 ≤ X < 5 1 Hour 15%

5 ≤ X < 10 1 Hour 25%

10 ≤ X < 15 1 Hour 45%

15 ≤ X < 20 1 Hour 75%

20 ≤ X < 30 0 Hour No Limit

X ≥ 30 0 Hour No Limit



Page 7

Where walls and unprotected openings enclose the exterior of exit stairways and the walls are exposed to other parts of the building at an angle of less than 180 degrees, the building exterior walls and openings within 10 feet horizontally of a nonrated wall or unprotected opening are required to have a fire-resistance rating of not less than 1-hour with 45-minute opening protection. The construction is required to extend vertically from the ground to a point 10 feet above the topmost landing of the stairway or the roof line, whichever is lower (780 CMR 1023.7).

Except as specifically permitted by 780 CMR 1010.1.9, doors are required to be readily operable in the direction of egress travel. Doors that serve more than 49 assembly occupants are required to have panic hardware if the doors latch or lock (780 CMR 1010.1.10).

Exit Enclosures

Exit enclosures are required to be enclosed in shafts having a fire-resistance rating as identified in Section 3.4. Exit enclosures must not be used for any purpose other than means of egress (780 CMR 1023.1). Openings through an exit enclosure are prohibited except for required exit doors from normally occupied spaces and for egress from the enclosure (780 CMR 1023.5). Penetrations into and openings through an exit enclosure are limited to the equipment serving the stair in accordance with 780 CMR 1023.6.

Exit Discharge

Exits are required to discharge directly to the exterior, except where permitted otherwise in this Section (780 CMR 1028.1).

A maximum of 50 percent of the number and capacity of exit enclosures are permitted to egress through areas on the level of exit discharge (780 CMR 1028.1).

Where exit enclosures egress through areas on the level of exit discharge, the following must be met (780 CMR 1028.1 Exception 1):



Page 15

• Occupants are provided with a free and unobstructed path of travel to an exterior egress door and such exits are readily visible and identifiable from the point of termination of the exit enclosure.

• The entire area of the level of exit discharge is separated from areas below by construction having a fire rating equivalent to the exit enclosure served.

• All portions of the egress path are sprinkler protected.

Exit Signage

Exit and exit access doors are required to be marked by an approved exit sign readily visible from any direction of egress travel (780 CMR 1013.1). The path of egress travel to exits and within exits must be marked by readily visible exit signs to clearly indicate the direction of egress travel where the exit or path of travel is not immediately visible.
