1. INTRODUCTION

1.1. GENERAL

1.1.1. This Manual provides policy and standards for the design, development, and revision of project documents such as plans, specifications, cost estimates, studies, and Requests for Proposals (RFP’s) for facilities at the Marine Air Ground Task Force Training Command—Marine Corps Air Ground Combat Center at Twentynine Palms, California (MAGTFTC-MCAGCC, hereafter shortened to MCAGCC, which designates the physical facility). This Manual supplements UFC 1-200-01 “General Building Requirements” and UFC 1-300-09N, “Design Procedures” by providing information, requirements and details that are site-specific to MCAGCC. UFC 1-300-09N, “Design Procedures” is modifies as follows:

1.1.1.1. PWD prefers the use of United States customary units in the design and preparation of construction documents. Do not use dual units on drawings This Manual applies to both Design-Bid-Build (DBB) and Design-Build (DB) projects.

1.1.1.2. For locally funded and HQMC funded projects, the Statement of Architectural Engineering Services (SOW) lists which deliverables and what quantities of deliverables the Government requires. This list will supersede the requirement for various deliverables described in Chapters 9 through 12 of UFC 1-300-09N.

1.1.2. Whenever a contract includes this Manual as an appendix or attachment, for example in a DB project where the Designer has a direct contractual relationship with the construction Contractor, replace every instance of the word should in this Manual, with the word shall.

1.1.3. Project documents shall conform to all applicable United Facilities Criteria (UFCs).

1.1.4. Refer to the MCAGCC Twentynine Palms Base Exterior Architecture Plan (BEAP). Bring any conflicts or deviations from the BEAP noted in this Manual to the attention of the Engineer in Charge (EIC).

1.1.5. Project documents shall conform to all conditions identified in the project’s National Environmental Policy Act (NEPA) Decision Memorandum. At project closeout the construction Contractor shall submit a certification to the Contracting Officer on company letterhead that the Contractor met the requirements of its Environmental Protection Plan (EPP) and the conditions of the Decision Memorandum during the construction period. An official of the Contractor’s company or a responsible employee who has personal knowledge of the Contractor’s compliance shall sign the letter.

1.1.6. The A-E accepts full responsibility for the technical accuracy of the project designs and professional quality of the products and services furnished. Before deviating from this Manual, confer with the EIC for approval.

1.2. DESIGN CRITERIA

1.2.1. Project designs shall conform to this A-E Design Manual, the project “Statement of Architectural-Engineering Services” or Scope of Work (SOW), and the latest edition of UFC 1-300-09N. Any deviations from these criteria require EIC approval.

1.3.1. Consult with MCAGCC’s Physical Security Chief and comply with the requirements of UFC 4-010-01.

1.3.2. Provide some type of barrier to prevent vehicles from breaching the stand-off. The preferred method to maintain the stand-off is an ATFP wall around inhabited facilities. See detail SKC- 38 for the preferred method. Other methods may be used in lieu of the wall; but they shall make for an aesthetic appearance.

1.4. DRAWING FORMAT

1.4.1. A/E/C CAD Standard: Comply with the latest edition of the standard available on the whole building design guide website.

1.4.2. The project SOW will indicate the quantities of deliverables needed and other submittal requirements. Most often these will include the submittal of scalable hard-copy drawings on 11” x 17” bond paper (ANSI B-size).

1.4.3. Use font sizes that are at least 3/32” high after photo-reduction of drawing sheets to 11” x 17”.

1.4.4. Orient drawings so that north arrows always point either to the top or to the left margins. Customarily, project north orients to the left margin on drawings in the MCAGCC archive. Project north for Mainside is 38.8 degrees west of true north. Mainside is MCAGCC’s primary area of development at its southern border.

1.4.5. As a rule, the north arrow shall appear at the bottom right corner of the sheet or detail.

1.4.6. NAVFAC drawing numbers are not required for locally funded or HQMC funded projects.

1.5. FIRE AND LIFE SAFETY DATA

1.5.1. The life safety plan, fire alarm system, and fire suppression system plans (shop drawings) require the stamp of a licensed Fire Protection Engineer (FPE) and must be approved by the Fire Department prior to construction.

1.6. AVAILABILITY OF EXISTING DATA

1.6.1. Existing utility maps, record drawings and other information may be available in hard copy or in electronic format for review and reproduction. Contact the EIC to obtain as-built information.

1.6.1.1. The A-E may need to provide CD-ROM’s or other acceptable media for copying electronic drawing files. Flash drives may not be connected to DoD computers.

1.6.1.2. The A-E may need to sign a non-disclosure agreement to obtain data. Allow two weeks for acquiring data.

1.6.2. The EIC is MCAGCC’s point of contact for project information and for access to

http://www.wbdg.org/ccb/DOD/UFC/ufc_4_010_01.pdf

http://www.wbdg.org/ccb/browse_cat.php?c=253


resources from Public Works Division (PWD) and other offices on the base.

1.7. FIELD INVESTIGATION AND REQUIREMENTS FOR DELIVERABLES

1.7.1. The SOW or RFP for each project addresses the types and quantities of deliverables required at each submittal.

1.7.2. The A-E shall make all requests for information, coordination meetings, field investigation and study through the project EIC. The EIC can provide points of contact as required.

1.7.3. The A-E shall coordinate with the EIC before entering, surveying, or photographing any facilities.

For security reasons, MCAGCC does not permit indiscriminate photography of base facilities. Coordinate in advance with the EIC so that the appropriate base personnel can be notified in a timely manner.

1.7.4. The A-E shall provide adequate notice and comply with the latest security requirements for access to MCAGCC.

1.7.5. The A-E shall complete field investigation prior to the 45% submittal.

1.7.6. Address design submittals, including those for Design-Build projects, to the EIC at PWD.

For additional guidance see UFC 1-300-09N.

UFC 1-300-09N uses the terms “Pre-Final” and “100% submittals” synonymously. These two terms generally refer to separate submittals at MCAGCC. At MCAGCC, the 100% submittal is as described in UFC 1-300-09N paragraph 10-4. The pre-final submittal consists of a stamped, wet-signed cover sheet and a few other items described in the SOW that the EIC may use to ensure that the final submittal will address previous review comments. This submittal is not for general review and the Government will not use it for construction or to advertise the project for construction. Instead, it satisfies an administrative requirement for PWD to deliver a fully signed drawing set in electronic format to the ROICC. The EIC and one or more accepting officials from MCAGCC will sign the title block. The EIC will then return this fully signed cover sheet to the design firm so the firm can proceed to the final submittal. Refer to the SOW for the pre-final deliverable requirements. These usually include:

1.7.6.1.a. Half-sized drawings (11” x 17”) marked Pre-Final Submittal and dated.

1.7.6.1.b. A half-sized (11” x 17”) print of the title sheet (G-1) with stamp and wet signatures. Note: mark this signed title sheet “Final Submittal,” not “Pre-Final Submittal.”

1.7.6.1.c. Annotated responses to 100% design submittal review comments.

1.7.7. Record Drawings: Prepare record drawings that reflect changes made during construction as well as existing conditions that differ from those known at the time the construction drawings were prepared. Revise the construction drawings to reflect as-built conditions at the completion of construction. The registered Architect or Engineer of Record in design-build contracts shall stamp and sign the record drawings. Incorporate the information gathered from the following sources:

1.7.7.1. Construction drawings annotated by the Contractor to indicate changes made



during construction.

1.7.7.2. Drawings and instructions issued during construction as responses to Requests for Information (RFIs).

1.7.7.3. Change Orders.

1.7.7.4. Substitutions.

1.7.8. Building designs at MCAGCC shall conform to the latest federal mandates and California Title 24 standards for energy consumption plus ten percent.

1.7.9. When projects require LEED certification, give priority to energy savings points.

2.1.2. Some buildings at MCAGCC contain hazardous materials such as asbestos, lead containing paints and mold. Some existing hazardous material surveys are available at PWD that may help designers review existing conditions and specify appropriate mitigation requirements. Additional surveys may be necessary in a project to avoid presuming the existence of hazardous materials and to ensure protection of human health and the environment. The SOW may require the A-E to perform such services. If such services are necessary and the SOW does not address them, then the A-E shall delegate them to the Contractor. Hazardous material surveys shall be completed prior to any renovation or demolition that affects hazardous materials. MCAGCC is located within the MDAQMD.

2.1.3. Natural Resources and Environmental Affairs (NREA) is the base authority on environmental compliance.

8.1. GENERAL:

8.1.1. The A-E shall consult with the EIC on the type of roofing system desired. New roofs shall conform to the BEAP.

8.1.2. Standing-seam metal roofs are preferred. Other types of metal roofing are prohibited, with the exception of pre-engineered buildings, sheds and uninsulated structures such as outdoor sunshades and patio covers.

8.1.3. Where standing-seam metal roofing is not feasible or at “flat” roofs (slope < 2:12) traditional built up roofing (BUR) or modified bitumen roofing may be used over composite type combination perlite board and polyisocyanurate, polystyrene, or polyurethane insulation over the roof deck.

8.1.3.1. Traditional built up roofing is field fabricated with layers of bitumen, alternating with plies of reinforcing felts.

8.1.3.2. Two different polymers, styrene butadiene styrene (SBS), and atactic polypropylene (APP), are used to modify the membrane to impart greater elasticity and resistance to punctures, extreme temperatures, and wind uplift. SBS is typically installed with hot asphalt or cold adhesives; APP typically utilizes the torch method.

8.1.3.3. Fluid applied elastomeric roofing may be used on roofs having multiple penetrations or irregular shapes, or restricted use of hot asphalt or heat welding.

8.1.3.4. Application of asphaltic or modified bitumen roofing is generally “hot” or “cold.” “Hot” application is most typical for new construction; “cold” application is used when a building is required to be occupied during reroofing so as to minimize exposure of occupants to noxious vapors or where the presence of heat or open frame is restricted. Fluid applied roofs are typically applied “cold.”

8.1.4. At least 75% of the roof surface shall provide a Solar Reflectance Index (SRI) of at least 78 at “flat” roofs (slope < 2:12) for a “cool roof,” per Cool Roof Rating Council (CRRC) guidelines.

8.1.4.1.

Provide 400 lb. per square white marble chips for aggregate surfaced built-up roofing, 72 lb. per square for standard mineral granule cap sheet, or 78 lb per square for mineral granule cap sheet that is specifically designated for “cool roof” use. Exact weights of stone aggregrate may


vary by manufacturer.

8.1.4.2. Where aggregate or mineral cap sheets do not provide an SRI of at least 78 an elastomeric acrylic latex roof coating, compatible with bituminous roof surfaces, shall be applied. Coating to be white in color and CRRC listed.

8.1.5. Provide asphalt impregnated roof protection boards for walkways. Provide space (gap) between boards to maintain roof drainage.

8.1.6. Composite shingles shall be nailed and not stapled.

8.1.7. Roof Slope:

8.1.7.1. Provide a minimum 4-inches per foot roof slope for standing-seam metal roofs.

8.1.7.2. Provide a minimum 1/2–inch per foot roof slope, including along valleys, to the low point (the roof drain or scupper) for “flat” roofs.

8.1.8. MCAGCC is a high wind area. Design all roofing systems to withstand uplifts resulting from winds in excess of 90 mph.

8.1.9. The required minimum R-value for roofing assemblies is R-30.

8.1.10. The required minimum R-value for wall assemblies in permanent inhabited structures is R-19, and R-15 for exterior walls in temporary trailer facilities.

8.2. MINERAL FIBER BLANKET INSULATION

8.2.1. Provide foil or Kraft paper faced blanket insulation.

8.3. STANDING-SEAM METAL ROOFING

18.1.1.2.e. Summer design data cooling wet bulb = 73° F for 1 % range.

18.1.1.3. Indoor design conditions:

18.1.1.3.a. Summer:

18.1.1.3.a.1. Dry Bulb = 72° F (+/- 3° F).

18.1.1.3.a.2. Wet Bulb = 50% RH (+/-10%).

18.1.1.3.b. Winter:

18.1.1.3.b.1. Dry Bulb = 78° F (+/- 3° F).

18.1.1.3.c. Note: In order to reduce energy consumption, the Energy Management office


uses a basewide EMS Control System that further limits some of the conditioned spaces during summer time to 75° F DB and during winter time to 72° F DB (Per UFC 3-410-01FA and local temperature data).

18.1.1.4. Temperatures below freezing dictate the following requirements for equipment and piping systems exposed to outdoor weather:

18.1.1.4.a. When cooling towers or evaporative cooling units will operate during the cold season, provide water pans with freeze protection features such as electric or hot water heating of water within water pans.

18.1.1.4.b. When cooling towers or evaporative cooling units will not operate during the cold season, then the water pans shall be drained. Provide manual draining valves for water pans.

18.1.1.4.c. For make-up water piping located outdoors, provide a drain valve at the lowest point to allow for manual draining; except for automatic dripping when utilized for freeze protection.

18.1.1.4.d. Due to freezing conditions, insulate all outdoor active piping systems, including small sized make-up water piping for HVAC systems.

18.1.1.4.e. Provide heat-tracing cables around various piping systems.

18.1.1.4.f. Use any other methods of freeze-protection common to standard practice that elements of the design dictate such as non-freeze hose bibbs (nitrogen filled heads).

18.1.1.5. Very high temperatures and dry outdoor conditions dictate that:

18.1.1.5.a. Evaporative cooling equipment such as cooling towers, industrial fluid coolers and rotary evaporative coolers are effective.

18.1.1.5.b. Air-cooled condenser units including packaged or split A/C units above five tons nominal capacity should not be used if chilled water distribution piping is available near a project site. When chilled water distribution piping is not available near a project site, then use a water cooled cooling tower system.

18.1.1.5.c. Cooling towers and industrial fluid coolers shall be oversized to compensate for very hot days in excess of 120° F DB with high humidity.

18.1.1.6. Wind direction: See Wind Rose; sheet SKC-28.

18.3.1.2. At North Mainside, from a co-gen plant (Project P-126).

18.3.2. The Central Heating Plant (CHP), building 1577, generates and distributes high temperature hot water to Mainside zones I, II and III.

18.3.2.1. Contact the EIC for any work related to generation of HTHW within the CHP.

18.3.2.2. The CHP distributes HTHW to various buildings, as described below, at 350° F temperature and 300 psi pressure. Contact the EIC for verification of HTHW operating temperatures and pressures at specific locations.

18.3.2.3. Any new branch take-off requirement that will tie into the existing HTHW lines shall, if feasible, use a “hot tap” to lessen the non-availability of supply to affected systems.

18.3.3. In addition to the CHP and its three zones, co-generation plants supply HTHW to Mainside zones IV and V. Each zone has a main supply and return loop. Within each zone there are branch loops interconnected to the main loop. HTHW supply and return branch loop piping connects each building.

18.3.3.1. At Mainside, the entire main loop, branch loop, and building supply and return piping systems for all of the three zones flowing from Building 1577 act as a “PRIMARY LOOP” distribution system.

18.3.3.2. Zones IV and V will each has independent pumps and each acts as a “Primary Loop”.

18.3.4. Refer to the latest available utility map for a description of zones, routes and piping sizes located underground, above ground and within concrete tunnels.

18.3.7.2. The cooling of buildings via absorption chillers for about eight months per year occurs during daytime.

18.3.7.3. The heating of buildings directly, using HTHW heating coils within air-handling units or HTHW space heating heat exchangers, for about four months per year occurs 24 hours per day.

18.3.8. HTHW absorption chillers are best for generating chilled water for the cooling of buildings. This provides “free” cooling for 8 months per year.

18.8.2.2. Industrial type control valves and industrial pneumatic actuators, by Honeywell, Fisher, Baumann or a pre-approved equal of Class 300 minimum to withstand pressure and temperature, are acceptable.

18.8.2.3. Due to temperatures in excess of 350° F, conduction of heat from a valve’s stem to its actuator occurs. Since heat damages electronic and electrical components, the use of electronic or electric type actuators is not acceptable.

18.8.2.4. Experience demonstrates that pneumatic actuators work well with HTHW control valves.

18.8.2.5. Selection of the valve flow coefficient (Cv) is very important to achieve finite control at low GPM.


18.8.2.6. SKM-06 and SKM-07 are sample details for HTHW heating coil piping. SKM-06, with two control valves, shows the “Split Range Concept” or the “1/3 and 2/3 Flow Concept”, which enables finite control at very low GPM demand while satisfying the maximum high GPM demand.

growth, voltage drop, short circuit heating, number of conductors within the raceway and ambient conditions.

20.1.4.1.a.1. For indoor installations and within air-conditioned spaces, the ampacity

tables for low voltage conductors in the National Electrical Code based on 30 C. ambient temperature may be used without temperature derating of the conductor. In

areas such as equipment rooms where the ambient temperature will exceed 30 C., derating of the conductors shall be calculated to the most extreme possible ambient temperature condition.

20.1.4.1.a.2. For outdoor installations and for low voltage conductors installed within metallic raceway in the shade, the ampacity tables in the National Electrical Code

shall be used with a derating factor for an ambient temperature of 45 C. Similarly, for conductors within metallic raceway installed in the sun, use a derating factor for

an ambient temperature of 50 C. Assume that the maximum load occurs during the time when the ambient temperature will be as noted above.

20.1.4.1.a.3. For underground installations, the ambient, temperature used for

conductors within a raceway is to be 30 C. This means the appropriate ampacity from the tables in the California Electrical code shall be derated to this temperature. The thermal characteristics of the medium surrounding the conductors are important to determine the current carrying capacity of the conductors. Factors affecting the current carrying capacity of the conductor include:

20.1.4.1.a.3.i. The type of soil in which the duct bank is buried and its thermal resistivity. Consider this when sizing conductors.
