Chapter 1 Introduction

Facilities’ design, construction, operation and maintenance at Edwards Air Force Base (AFB) shall be based on incorporation of industry standards and the systematic analysis of life-cycle benefits received for the cost incurred. Design of the physical plant shall ensure that the facilities are “fit for use” and provide facility conditions that effectively, efficiently and safely support Edwards AFB’s current and future mission needs. In addition, sustainable design principles shall be applied from site planning to facility design, construction and operation to ensure resource efficiency of the building and improve the health and productivity of the occupants. The safety and health of the base employees, public and any possible impact to the environment, shall take precedence over project issues such as performance, cost or schedule.

These design standards are generally applicable to all disciplines on all projects. All construction, major/minor repair and renovation projects should be functional and cost effective. Facility projects shall be tailored to fit its intended function, with emphasis on low-maintenance and energy efficiency. Facilities should be constructed to be easily maintained, with readily accessible equipment areas and quality systems. To promote an orderly and efficient appearance, architectural features of new facilities shall complement and enhance existing architecture at the site.

Close coordination and development of civil, landscape, structural, architectural, fire protection, mechanical, electrical and security features are expected to ensure compatibility with planned functional equipment and to facilitate constructability.

1.1 General Design/Construction Requirements

A scope of work (SOW) describes the basic requirements, goals and design objectives of a project. Typically, this statement is written by the 412th Civil Engineer Group (412 CEG).

The formality and detail of this SOW will vary depending on the size and/or complexity of the effort.

Timely submission of contract-required design and construction plans are essential to the achievement of a fully cooperative design that maximizes customer satisfaction. All design and engineering documents as well as construction and material submittals shall be reviewed by the Edwards AFB Fire Protection Division Technical Services Bureau and Air Force Civil Engineering Center (AFCEC), for compliance with Department of Defense (DoD) and Edwards AFB requirements.

The practice of architectural, engineering and design procedures where specifically regulated in applicable codes referenced by this Design Standard shall be complied with. The Unified Facilities Criteria, its ancillary Standards and Air Force (AF) Technical letters - are in aggregate a Federal code that shall be viewed as the basic code. Specific areas of architectural and engineering design reserved for licensed professionals by California State Statutes and professional boards shall be respected. The requirements of the California Board of Architects, the California State Board for Professional Engineers, Land Surveyors, and Geologists, the provisions of the California Business and Professions Code, and the California Code of Regulations shall be met. Specialty design and construction of infrastructure systems shall be

FA4610-17-R-0002

Attachement 1h

Edwards AFB Design Standards Page 9 performed only by specialty contractors holding the appropriate type and Class of License as issued by the California Contractor State License Board. An Out of State Entity performing design and construction services at Edwards AFB may submit equivalent levels of competency as certified by regulatory agencies for their home state. For conflicts between Federal, State and Local regulations, the strictest shall apply. Design, Design-Bid-Build and Design-Build methods of construction documentation and delivery shall be the strictest and best of current industry practices as well as what is specified by all applicable regulations and codes.

It is not the intent of these standards to re-state specific Federal, State, AF or Local Standards.

Reference to specific standards within this document is done for emphasis only, and must not be interpreted to imply that other legal and regulatory requirements are not required. These standards have no authority to overrule any State or Federal law or regulation. Any conflict between these Standards and other applicable standards must be brought to the attention of the 412 CEG Project Manager (PM) as soon as possible and timely resolution requested.

During the construction stage for all 412 CEG projects, if the customer is in a secure location and requires an escort, it is the program (customer) responsibility to provide an escort for contractor personnel. The 412 CEG and/or Army Corps of Engineers (ACoE) are not responsible to provide contractor personnel escort to the construction sites in required areas.

Key Concepts

Energy and Water Conservation. New construction, substantial remodeling or large energy or water consuming system replacement will not be done without connecting that facility or system into the existing Energy Monitoring Control System/Supervisory Control and Data Acquisition (EMCS/SCADA) system. Water conservation measures are to be designed into and implemented on all new construction or substantial remodeling projects. More information on EMCS/SCADA can be found in Chapter 8.

Utility and Water Metering Requirements. All new utilities, including water installations, must be metered. Metering is required at each individual facility. Sub-metering within facilities is acceptable if required to determine energy and water use across organizational lines or if significant processes for energy or water use differences exist. Meters must be compatible, remotely readable and connected to the current EMCS/SCADA system. More information on EMCS/SCADA can be found in Chapter 8.

EMCS/SCADA Integration. The heating, ventilation and air conditioning (HVAC) and lighting systems of many buildings on Edwards AFB are currently integrated into our base-wide EMCS/SCADA system. The operating characteristics of existing and new equipment and the connectivity of these buildings to the EMCS/SCADA system must not be diminished by any building revisions. Facilities not currently integrated into the base-wide EMCS/SCADA system undergoing significant HVAC upgrades or large system replacements, must include full and effective system integration as part of the upgrade or replacement.

Architectural Barriers Act (ABA). Edwards AFB maintains compliance with all legal requirements of the ABA. All new facility construction and renovations must meet prescribed ABA standards as specified by the 2012 International Building Code (IBC) and the 2013 California Building Code (CBC) (updated versions and/or amendments to these documents

FA4610-17-R-0002

Attachement 1h

Edwards AFB Design Standards Page 10 should be used). In the event of conflict, the code standard resulting in the greatest accommodation will apply. Any military or special-use exclusion, consistent with the ABA, must be noted and documented.

1.2 Project Siting and Site Construction Limit Requirements

Prior to design, construction projects are reviewed specifically to determine the best acceptable site. Often, a project is granted siting approval subject to a variety of conditions which must be adhered to in the design and construction of the project.

The site parameters vary with each project, including but not limited to concerns such as access, parking considerations, utility relocations, flood plain issues, noise proofing requirements and environmental concerns. To determine the specific restrictions associated with each project site, the Contractor and the PM must contact the Community Planner. Any change in the site location of a facility, even those minor in nature, must also be coordinated with the base Community Planner and appropriate actions and/or approvals sought prior to construction.

1.3 Job Site Standards, Contractor Storage and Laydown Areas

When projects are under design or in planning, specific areas will be designated where contractors locate a construction office trailer and stockpile tools and materials. These areas will be designated by facility managers responsible for the land used by the construction effort. The locations will be as convenient as possible to the work site where visual impact to the rest of the installation will be minimal. The PM will review all locations proposed for on-site construction office trailers and approve the location as a pre-construction conference agenda item. Edwards AFB may limit the number and location of various construction and office trailers, temporary structures and open storage and staging areas used by the contractor. These facilities are to be clean, in good condition and free of rust or surface deterioration. Specifications to enforce these requirements shall be included in each project. The following specific requirements apply:

Portable toilets needed by the contractor will be permitted at the construction site at a location that minimizes the visual impact and shall be within the construction fence

When fencing is required to restrict access, impact to construction work or to provide site safety, fencing shall consist of conventional chain link fence and will be screened

All required signs for construction shall be combined into a single on-site sign. This sign shall include information on the standard ACoE project information (for those projects where applicable) and the contractor's business name

Mandatory "Hard Hat Area" signs will be posted as safety regulations dictate

Construction office trailers shall be in good repair and of minimum size

The preservation of all natural resources including the undisturbed desert areas within the main base cantonment area requires the minimization of laydown and construction assembly and storage areas, as well as strict limitations on the area of construction-related disturbance on the

FA4610-17-R-0002

Attachement 1h

Edwards AFB Design Standards Page 11 site. All site disturbances during and throughout construction on previously undisturbed sites must be limited to:

40 feet beyond the building perimeter

10 feet beyond surface walkways, patios, surface parking and utilities less than 12 inches in diameter

15 feet beyond primary roadway curbs and main utility branch trenches

Any laydown or staging areas outside the construction site must receive approval prior to utilization

If larger staging areas are required to limit compaction on previously constructed areas with permeable surfaces (such as pervious paving, stormwater retention facilities and playing fields), disturbance up to 25 feet is allowed and will be permitted on a case by case basis.

Utility connections from contractor owned/leased office trailers on the construction site can be established at the expense of the contractor, not the government. Infrastructure may not be provided directly to the site. However, pending availability, it can be utilized by the contractor.

Utility mains may be a significant distance from construction; the contractor is responsible to connect utilities at their expense. Utility usage requirements shall include, but are not limited to the following:

Minimize idling of construction equipment

Turn off lights when an area is not occupied

Reduce heat when an area is not occupied

Provide enclosures to prevent unnecessary heat loss from building envelope

Minimize water use

When storage area and or laydown areas are no longer needed, the contractor is responsible for all clean-up efforts and any costs that may be incurred due to environmental remediation caused by the contractor. Contractors are required to clear the work site with the PM prior to end of contract.

Depending on the contract, sometimes it is not feasible to have a laydown or storage area co-located to the work site. If this is the case, a laydown area on Contractor Hill Road will be provided as the official area for the contractor. This area will be based upon the contractor’s requirements. A specific space assignment will be designated after contract award by the 412 CEG Community Planner. The contractor will contact the Community Planner at

(661) 277-9456 prior to mobilizing and request a space through that office. The designated lot on Contractor’s Hill Road will be used for the contractor’s office trailer, vehicle parking and supply storage. The site office shall be manned continuously during standard working hours, and have the Contract Manager onsite. The contractor shall be responsible for the connection of all utilities.

Once the performance period of the contract or last task order has ended and upon notification from the Contracting Officer, the contractor shall contact the 412 CEG Community Planner to

FA4610-17-R-0002

Attachement 1h

Edwards AFB Design Standards Page 12 schedule a move-out inspection prior to leaving the site. Under no circumstances will any equipment, trailers, portable buildings, conex type facilities or any other structures be left on site once the contract is complete. In addition, no waste of any kind, non-hazardous or hazardous will be left on site. The site will be reverted back to its original condition prior to its current use. Before departure, the contractor shall contact the Contracting Officer, Contract Manager and 412 CEG Community Planner for the final move out inspection before leaving the base. Any deficiencies noted will be corrected by the departing contractor before vacating the space.

1.4 Computer Aided Design (CAD) Requirements

The as-built drawings shall be delivered in the form of digital media, plots and related documents to comprise a complete set of drawings for evaluation and approval to the PM. All dimensions shall be expressed in English Imperial (inch-pound) and Standard International metric units.

Red-lined as-built drawings will be developed and submitted on 30 inch x 42 inch sheets. The as -built drawings shall be complete, detailed drawings and shall accurately depict the as-constructed or as-built conditions of the project. All reproducible material shall have sufficient contrast to reproduce clear and concise prints. All red-lined as-built drawings shall be stamped “AS-BUILT” and must be signed and dated by the contractor to reflect dates as-built corrections were made to the digital graphic as-built files.

Digital Files. Where contractors include inspection of construction, all changes made to the design during construction shall be indicated in the CAD drawing files. The revised CAD files must be a true representation of the final as-built construction. All graphic information on consolidated composite drawings (CCDs) and shop drawings provided by the construction contractor, shall be merged into the CAD files. Where CAD graphics are duplicated on CCDs or shop drawings, the duplicates will be deleted leaving a single copy of each graphic element in the revised CAD file. The revised CAD files shall be delivered to 412 CEG, Engineering Division, Execution Support Office (412 CEG/CENME) within 90 days after completion of construction.

The completed as-built drawings which incorporated all field corrections/changes shall be delivered in digital CAD format on a compact disc. Each drawing shall utilize the standard Edwards AFB title block and follow the prescribed parameters. All digital graphic files will conform to the Tri-Service Standard A/E/C CAD Standards, which 412 CEG/CENME will provide in digital format upon request.

Format Specific Requirements. All files submitted in AutoCAD® format shall conform to the following requirements:

All external reference files or “XREFS” used to create a particular sheet in the drawing package shall be “bound” and “inserted” into the source file sheet. CAD files with multiple sheets or drawings are not acceptable. Each drawing sheet should be represented by only one CAD file

Chapter 2 Architecture

This section of these standards is intended to provide the minimum standards, procedures and materials for facilities at Edwards AFB. All new facilities and additions built on Edwards AFB should be compatible with the permanent facilities already in existence.

Color, texture and pattern must all be considered not only in the context of the building being designed, but also in the larger context of the site and neighboring buildings. Durability and low maintenance are also vital to a successful design.

Development of base facilities shall adhere to a general architectural style which includes sophisticated and modern solar control features – deep overhangs, recessed windows and wind and weather protected entrances and exits.

2.1 Base Facility Color Scheme

Dunn-Edwards Nomenclature is as follows:

Base Exterior Color: Marble Creme Primary Accent/Trim Color: Nebular Redwood Secondary Accent/Trim Color: Big Stone Brown Interior Color: Swiss Coffee

When ordering paint from Dunn-Edwards, please call (661) 224-1988 and indicate you are calling for paint to use at Edwards AFB. Only those in the Edwards AFB Facility Color Scheme are acceptable colors for painted or factory finished items. If deviations from the base color scheme are desired, they must be justified by considerations rather than convenience or cost. Deviations are permitted only with the specific approval of the BCE. The prime contractor will submit the color samples for approval prior to application.

Paints. All paints/coatings shall comply with Eastern Kern Air Pollution Control District (EKAPCD), Antelope Valley Air Quality Management District (AVAQMD), Mojave Desert Air Quality Management District (MDAQMD) volatile organic compound (VOC) requirements of 100 grams/liter VOCs, unless the coating meets the definition of a specialty coating.

BURs shall be concealed by parapet walls; roof shall be a minimum 3-ply BUR with a mineral cap sheet; gravel on BURs is not allowed. BUR installation shall be scheduled to complete each area of work on the same day. Install temporary water cutoffs and tie-ins at the end of each workday. Remove temporary cutoffs and tie-ins on resuming work so that all vertical faces of insulation are exposed.

White Roofs or Cool Roofs. May be used on nominally flat roofs which enhance the desired effects/benefits of the white surface. The term “cool roofs” and “white roofs” shall be taken to mean a roof that meets state of the art geo-engineering standards for high solar reflectance and high solar emittance in its technical specifications. The standards are set by the Energy Star Program. For the visual aesthetics established by the base, only low slope roofs (preferably hidden by a parapet wall), may literally be white in color. These flat roofs shall have an Energy Star rating of .78 initial and .50 aged. Note: These roofs are not necessarily white in color.

Roofs that are clearly visible shall maintain the visual character and aesthetics of Edwards AFB.

Large, arched clear spanned structures such as hangars that are roofed with monolithic sheet may become cool roofs with a Marble Creme color to match the standard. Monolithic roofs shall have an initial reflectivity of .65 and weathered reflectance of .50, with a life cycle expectancy and warranty period for durability of conventional roofs.

Standing Seam Metal Roofs. Standing seam roofs shall be shop fabricated. On-site fabrication of panels is not acceptable. Roof panels with lap type longitudinal side joints or those requiring battens, gaskets or other non-integral sealing means or exposed structural fasteners are not acceptable. Standing seams must wrap onto and down the fascia whenever used. Roof panels shall be fastened to the secondary support members with a concealed clip or backing device of steel having a protective metallic coating. Through penetration of the roofing surface by exposed fasteners shall occur only for non-structural flashing connections at terminal locations of the roof panels.

Standing metal seam roofs shall be sloped a minimum pitch of 1/2 inch per 12 inches, to a maximum pitch of 6 inches per 12 inches. If installation is over an existing roof, provide positive free air ventilation between the new and old roof. Low profile vents shall be incorporated into the roof. Low profile intake ventilators shall be provided near the new eave line. The ventilators shall be constructed and finished to match the roof panels.

Roof hold-down clips, penetrations and terminating flashings must allow the weathering metal membrane and its components to expand and contract uniformly with temperature variations.

Special care must be used if panel runs exceed 50 feet.
