BASE FACILITY DESIGN STANDARD HILL AIR FORCE BASE

13 Apr 2017

Table of Contents

1. INTRODUCTION

This Facility Design Standard is intended to alert designers, design-build contractors, facility users, and others the facility design requirements that are peculiar to Hill Air Force Base including remote sites under the base jurisdiction. This standard supplements or emphasizes established design criteria in government and industry publications including standards, codes, regulations, policies, directives, etc. This standard is being continuously revised and updated as regulations and policies change. Caution must be taken to ensure the latest edition is used. Many governmental jurisdictions have adopted statutes, administrative rules, and/or ordinances that set standards regulating professional practices within their jurisdictions. In addition to the standards set forth herein, said professionals shall also conduct their services in accordance with applicable jurisdictional requirements and standards of practice. Where level of effort differs between the standards set forth herein and any such jurisdictional requirements and/or standards of practice occur, the more stringent requirement(s) shall apply. However, if there are conflicting requirements the government standard will govern.

2. SPECIAL CONSIDERATIONS:

2.1 Base Location:

Hill Air Force Base is located near Ogden Utah approximately 30 miles north of Salt Lake City at an elevation of 4700 Ft above sea level.

2.2 Construction Season Limitations:

Earthwork can normally only be accomplished from 15 March to 15 November. Paving is normally accomplished from 15 May through 1 October. Structural work may generally be accomplished on a year round basis, but it must be protected from temperature extremes. Built-up roof construction is generally limited to the period from 15 May through 15 October.

2.3 Soil and Foundation Considerations:

Typical soils range from sand to silty sand with thin discontinuous layers of silty clay and clayey silt being common. Potable wells have a static water level of approximately 500 feet below the surface. However, the perched water may be encountered at more shallow depths. The average soil pH is approximately 7.8. The soil resistivity ranges from 2,000 to 15,000 ohms/cm. Spread footings are the typical structural foundation. All footings shall be at least 3 feet below grade.

2.4 Surveying:

2.4.1 Purpose: These standards are written to provide the Hill Air Force Base Contractors a guideline for producing adequate and accurate topographic and record drawings. These standards do not generally apply to architectural, mechanical, or electrical detail data inside of a building or structure. Definitions used in these requirements refer first to Definitions of Surveying and Associated Terms as published by the American Congress on Surveying and Mapping and second to Black’s Law Dictionary. It is the intent of these requirements to:

2.4.1.2 To provide data that meets accuracy standards required for new improvements consistent with Hill Air Force Base’s Geodetic Control Network and Geographic Information System.

2.4.1.3 To provide information necessary to maintain current building and infrastructure data for end users (airmen, base employees, contractors, planners, designers, constructors, emergency personnel, ext.).

2.4.1.4 To provide a means of schematic verification that the intent of the approved engineering design has been met, thereby substantiating that the health, safety and welfare aspects of the engineering design have been adequately provided for by the construction of the project.

2.4.2 Geodetic Control / Monuments: Hill Air Force Base will make available all unrestricted Geodetic Control information to be used for survey purposes. All coordinate values for survey points shall be reported in:

Universal Transverse Mercator coordinates (UTM), Zone 12 North.

The basis for all elevations shall be the North American Vertical Datum of 1988 (NAVD 88). GPS derived orthometric heights shall be calculated using the Geoid 09 model. The EPOCH shall be defined by the user at time of survey. The basis for all units of measure shall be meters.

For more documentation, including station descriptions, of Hill Air Force Base’s Geodetic Control Network, contact the base Installation Geospatial Information & Services (IGI&S) (GeoBase) office.

All base geodetic control monuments disturbed by construction shall be replaced by the contractor. Furthermore, one additional geodetic control monument shall be set for every 20000 square meters of construction area or land area otherwise disturbed for construction.

All new and remodeled facades shall blend with and complement the permanent construction of the installation.

4.2 Definitive Design:

Refer to the AFMC Facility Quality Program Manual as a guideline for Air Force Standards.

4.3 Interior Design:

4.3.1 Carpets: Comply with AF ETL 07-4. Carpets will contain a definite pattern and shall be suitable to the function area. All carpeting will meet the flame spread rating required in the Life Safety Code.

4.3.2 Sound Attenuation: Any building design requiring reduction of exterior generated noises shall be done in accordance with the Uniform Building Code, Chapter 35. Also consult the Hill Air Force Base Air Installation Compatible Use Zone Report, amended April 1982, for further sound attenuation guidance.

4.3.3 Noncombustible material: The installation of exterior finish material shall comply with the requirement that at least 75 percent of the total interior wall surface of any one room must be of non-combustible material, Class B. This material must have a flame spread of 75 or less. Wood paneling will not be used. Wall carpeting will have a smoke development rating of 25 or less.

4.3.4 Concealment: All wiring, piping, and ductwork will be concealed whenever possible.

4.3.5 Interior Graphics Systems: An interior graphics system will be used where appropriate to control message size and complexity, to establish a specific lettering style, establish a color scheme, and enhance the overall interior environment.

The cubicles should be appropriately for the use intended but under no circumstances should be less than 48 square feet. The electrical designer, the architect, and the interior designer must coordinate during the design process. Systems furniture is typically specified and ordered when construction is nearing completion; therefore, if proper coordination has not occurred earlier in the design process, field interface problems will occur. Specify an 8-wire harness consisting of 4 circuit conductors, 1 oversized neutral conductor, 1 full sized neutral conductor and 2 separate equipment grounding conductors. Provide oversized neutrals to match the harness configuration and balance loads between circuits and phases. A single circuit must not serve more than 4 cubicles under any circumstances.
