CODES AND STANDARDS

The design, construction and installation of all Department of Veterans Affairs Regional Office (VARO) systems shall be in accordance with this document and with the latest editions and/or revisions of all applicable codes and standards. Compliance with current provisions of governing Codes and Regulations in effect during the progress of the work is also required. Where there is a conflict, the more stringent code and/or standard shall be applied.

Nothing contained in this document shall be construed as authorization or permission to disregard or violate local and legal requirements.

On VBA owned properties: “As an agency of the federal government, VA is not subject to local imposition of code enforcement procedures (drawing reviews, building permits, inspections, fees, etc.). VA must function as the Authority Having Jurisdiction (AHJ) and thus has the responsibility to guard public health and safety through enforcing its adopted codes. However, local authorities should be notified about planned projects and given opportunity to review drawings provided that VA does not pay for review or inspection fees.” - VA Design & Construction Procedures Guide

To insure compatibility with private sector commercial standards and local practices, commercial grade methods and materials shall be incorporated into the design and construction of VAROs. The contractor is to install complete and fully operational systems, tested and approved by Department of Veterans Affairs (VA) Officials. VA will also provide input on all options as identified herein or on a project-by-project basis.

CODES AND STANDARDS

ARCHITECTURAL

ARCHITECTURAL - GENERAL PROJECT STANDARDS

Building Construction The most important design criteria for a VARO building is the flexibility to accommodate change. The VA office environment can be expected to undergo many changes over the life of the building. A basic rectangular shaped building, approximately 100 feet by 200 feet, with column bays, 30 feet by 30 feet and a 20,000 to 35,000 square foot floorplate, is preferred. This type of configuration works well when designing for good building circulation efficiency. The rectangular footprint can be repeated for additional floors to meet space requirements.

Exterior Window Wall System Energy conservation, comfort of the occupant and aesthetics of the building will control the design and glazing options. The color of the glass, its reflectance, UV transmittance, optimum range of U-Value and solar heat gain are important criteria that should be considered in conjunction with heating and cooling requirements. An adequate condensation resistance factor (CRF) and continuous thermal breaks in the window frames are essential to prevent condensation from forming on window surfaces in certain climates.

Opaque Walls and Louver Areas Opaque wall materials shall be selected for durability and low maintenance. Brick and precast concrete are appropriate materials. Metal louvers incorporated in the wall for air intake or exhaust shall be extruded aluminum, sight proof and weatherproof, approximately 50 percent efficient and backed with insulated and sealed blank-off panels where not active. Louvers shall be manufacturer standard finish to match exterior window wall system and shall have screens at all active areas. The VA shall approve the colors.

Roof Construction Roofing materials shall be selected to meet the requirements of the local climate and wind zone. Provide insulation material and vents which are compatible with the roofing manufacturer’s requirements and current IECC. Protect the roofing material with paver pathways to service equipment and address current NFPA 1 requirements for access. Roof drainage design should consider pedestrian pathways to ensure hazards to occupants and visitors are minimized.

Flag Poles A ground mounted flagpole, located preferably at the left of the entrance or front of the building, close or adjacent to the main entrance. It is preferable for the flag to be illuminated. The height of the pole should be around 32 feet.

Placement:

• If you are facing the building, the proper placements of flags are as follow:

o If the center flag pole is taller in height, the US flag is in the center with State flag on the left and

VA flag on the right.

o If the flag poles are in line and in the same height, from left to right are: US, State and the VA flag.

ARCHITECTURAL

Building Graphics and Signage A program for both interior and exterior signage is required. A wayfinding system should be designed which incorporates all aspects of the veteran’s navigation to the facility. At a minimum, exterior signage for the VARO shall consist of a lighted monument sign, traffic, directional and parking signs. All signage designs are to be approved by VA. Coordinate signage design in accordance with local zoning requirements. For general signage-http://www.cfm.va.gov/til/spclRqmts.asp#SIGN

First Impressions The VBA First Impression Program is a comprehensive, nationwide effort to improve the appearance of the main entrance and Public Contact areas inside of the regional offices. Although it depends on the configuration of each site, the program is comprised of unifying and common identification signage by creating a powerful fusion of images that visually depicts the Veterans Affairs mission, goals and outreach programs, supporting its United States of America veterans.

These graphic images convey the first impression of the Agency's services to both visitors and employees.

These environmental graphic displays help to demonstrate the Agency's mission of supporting and caring for the needs of service personnel and their families as well as how these services have developed and been enhanced over the years. Installation of the graphics will be prioritized based on newly designed or renovated regional offices as part of the construction documents.

Pending availability of funds, the placements of the First Impression Graphics are:

• Main Lobby o Full height fabric panels or other large media.

• Public Contact reception/waiting area o Inkjet print on Melamine Panel or print on frosted film over glass if it is available.

• Walls within VSC in strategic location o Mural Graphics printed on Wallpaper.

If there is a desire or need for artworks other than First Impression, the following criteria has to be followed as bases for the selection and installation:

• All graphics and images to be framed the same size throughout.

• All frames within the same office to be of the same material and color.

• The frame thickness should not be more than 2 inches.

• The theme of the art works to represent happy and joyful moments of veterans and not ammunition or war actions or sceneries.

• The images respect all people, men and women, with every ethnic background.

• Frames to be installed at eye height.

• When possible, use non-glare glass.

• When installing the frame ensure that the hanger or mount is properly supported with blocking.

5. Unit to be dedicated to the space.

Space Temperature Controls Individual rooms to be provided with separate temperature controls where possible. However, the following spaces may be grouped as one temperature control zone where building systems require:

• Perimeter rooms of similar size and occupancy with the same exposure and similar wall and window areas in groups not to exceed three.

• Interior offices of similar size and occupancy in groups not to exceed four.

• Spaces that are primarily for staff use may allow a +/- 2°F temperature adjustment.

• Spaces that are high occupancy areas (30 persons per 1,000 sq. ft.) to be evaluated for the feasibility of using a CO2 sensor and/or occupancy sensors to save energy during part load conditions.

Ventilation Base minimum outdoor air ventilation provided to be building on most current version of ASHRAE-62 - “Ventilation for Acceptable Indoor Air Quality” or the Ventilation chapter of the most current version of the International Mechanical Code.

Outdoor air intake locations to be installed in locations as required by the VA Physical Security and Resiliency Design Manual

Acoustic Requirements

Select spaces within the facility have requirements to reduce sound transmission between rooms. Space walls to be constructed with a minimum sound transmission coefficient (STC) rating of 50. This quantifies the sound insulating performance of the building elements, such as walls, ducts, piping, and other wall penetrations. Critical spaces include private offices, interview rooms, meeting rooms, and training rooms.

The ceilings to be constructed with equivalent sound barriers and /or extension of walls to the solid structure above (slab to slab). The systems should be designed and installed to reduce noise and prevent sound transmission. Any penetrations through these walls need to be protected to minimize sound transmission. One potential method to protect duct openings in walls is to provide transfer ducts in “U” configuration with acoustic duct lining. Pipe penetrations through walls to be fully sealed with acoustical material. Refer to sample details below.

Apply the requirements of the most current version of ASHRAE Standard 90.1 “Energy Standard for Buildings Except Low-Rise Residential Buildings”. These standards apply to the building envelope, energy distribution, systems and equipment for exhaust, heating, ventilating, air-conditioning, service water heating, lighting, and energy management. Provide certification to VA that the building is in compliance with these standards.

Utilities All utilities to the building are to be provided in accordance with the VA Physical Security and Resiliency Design Manual.

Equipment All HVAC equipment to be installed above the ground floor, above grade, and in an area not subject to flooding as required by the VA Physical Security and Resiliency Design Manual

Return Air System In general, the use of a ceiling return air plenum system is acceptable. However, all return air in the mechanical rooms should be ducted. All duct openings through full height walls to be protected with sound control transfer ducts. Sound critical areas should have protections in place to prevent sound from passing between spaces through the return system.

Ductwork All ductwork in the building to be galvanized steel rectangular or spiral round. Interior ductwork to be G60 galvanized. Exterior ducts to be G90 galvanized. All ductwork to be sized for a 0.07” pressure drop per 100’. Supply and outdoor air ductwork to be insulated with external insulation. All insulation thickness to meet the requirements of the most recent version of ASHRAE 90.1.

MECHANICAL

Piping All hydronic piping to be either copper with soldered joints or steel piping with threaded joints. All piping to be sized per ASHRE 90.1 pipe flow requirements including restrictions based on system operating hours.

Exhaust Provide exhaust air per the most current version of the International Mechanical Code as well as ASHRAE Standard 170 for medical spaces and ASHRAE Standard 62.1 for non-medical spaces. Spaces that require exhaust air include but are not limited to restrooms, janitor’s closets, and copy rooms.

Exhaust air discharge locations to be installed in locations as required by the VA Physical Security and Resiliency Design Manual

Humidification

Winter humidification is not required except in areas where outdoor design temperature is 0°F or below. Provide humidification through fresh air handlers in general office areas of the building where required. Adverse static electricity buildup could result in personal computer and printer damage with very low indoor air humidity. Humidification set point 20% RH and dehumidification set point with 60% RH as maximum.

Electrical/Telephone/Data Closets Active, heat producing equipment housed within electrical, telephone, or data closets are to be provided with dedicated cooling units for each closet. Building automation system to monitor the room temperature in all electrical, telephone, and data closets.

Main Server Room Air Conditioning/Humidification In new computer rooms, in-row, rack mount air-conditioning is the VBA standard.

A minimum of two computer room air-conditioner (CRAC) units are required, N+1 redundancy is required.

Refer to ASHRAE for temperature and humidity requirements. Maintain Humidity at 40% RH, plus or minus 5% non-condensing. Position the units at opposite ends of the computer room (preferably diagonally opposite) to ensure even distribution of conditioned air from both units. Typically, both units will operate sharing the load unless one fails or is undergoing maintenance. Redundancy is to be built into the system which may be such that failure of any one pump, compressor, blower, or the like will not result in computer room over-temperature. The cooling capacity of each CRAC unit should be adequate to remove all the sensible heat from the computer room. If a standby power source is available, it should be connected through an automatic transfer switch to the CRACs.
