DIVISION 50 – MINIMUM DESIGN REQUIREMENTS

SECTION 50 50 00 – 19th CES CIVIL/STRUCTURAL DESIGN CRITERIA

AND EXPECTATIONS

PART 1 - GENERAL

1.01 GENERAL

A. It is not the intent of these standards to inhibit design creativity. The intent is to introduce the designer to LRAFB standard design practices.

B. Sustainability

1. MILCON projects are expected to meet minimum LEED criteria for sustainable design.

Each such project will define a rating expectation (silver, platinum, gold, etc.), and decisions will be required on which ones are attainable for the project.

2. A life-cycle cost analysis is expected for selection of any roofing system other than SSMR for new construction. Results of that analysis, and resulting recommendations, are expected at the 35% design submittal.

3. All designs shall consider recycled material products. Products that utilize recycled materials shall be highlighted in the design analysis.

C. Codes and Requirements:

1. Designers shall conduct a thorough code review, and include all applicable requirements into the design. Listed below are some design requirements and resources:

B. HORIZONTAL DATUM:

The Arkansas State Plane Coordinate System (ASPCS) South based on the North American Datum of 1983 (NAD83) shall be used as the coordinate system and horizontal datum for projects.

C. VERTICAL DATUM:

The vertical datum shall be the National Geodetic Vertical Datum of 1988 (NGVD88). If the vertical datum for the prior surveys are determined not to be based on NGVD88, the surveyor shall provide the conversion formula relating to other known datum’s of record.

D. TERPS

Follow datum requirements of AFI 11-230. AFI 11-230, dated 30 Mar 2010, paragraph

1.5.12.3 states: All coordinates must be expressed as World Geodetic System-84 (WGS-

84) coordinates to at least two places past the decimal, with the map being associated to this coordinate system. The State Plane Coordinate System is not an acceptable aeronautical survey format.

E. MONUNMENTS AND BENCHMARKS:

1. Follow standards of US Army Corp of Engineers, Engineering and Design, Survey Markers and Monumentation, EM 1110-1-1002. This can be downloaded at http://publications.usace.army.mil/publications/eng-manuals/ .

2. Records and maps of known on base monuments and benchmarks can be obtained from 19CES Engineering Flight, Technical Support Section

3. New Monuments and Benchmarks shall be set by a Licensed Surveyor.

Information who installed the benchmark, and any useful notes to aid in locating the benchmark.

5. Typical Monument Caps can be viewed in Appendix B of EM 1110-1-1002. Utilize the typical monument cap layout and size in a type compatible with the type of monument being set. In lieu of “CORP OF ENGINEERS – US ARMY” monuments shall bear the heading

6. Monument and Benchmark Type and Construction Details: Follow EM 1110-1-1002 Chapter 3.

7. Typical monuments on LRAFB would be a Type G monument as defined in EM 1110-1- 1002. The construction details are illustrated in Figure 3-12. The Type G mark is constructed by excavating a 15-centimeter (6-inch)-diameter by 60-centimeter (2-foot)-deep hole. In areas where the maximum frost depth is greater than 2 feet, the excavated depth should be 1 foot below the maximum frost depth. The USACE disk may be driven into a 4-foot by 3/4-inch diameter pipe or on a 4-foot by No. 5 reinforcement steel bar (rebar). The pipe or bar assembly is then driven into the center of the hole until the disk is slightly above the surface. The hole is then filled with concrete to the disk. The use of a pipe or rebar is optional. The disk may be pushed directly into the fresh concrete; however, a magnet shall be placed in the concrete if pipe or rebar is omitted. The reactive nature of non-common materials may cause problems when placing aluminum caps on rebar. The use of a plastic insert serves as a barrier for the reaction and may prolong the life of the monument. The plastic insert is not necessary when using a standard brass disk. Below is a figure of a Type G monument.

8. At a minimum new benchmarks shall be set as follows: 8” Diameter concrete collar, 24” deep, with a 5/8” rebar approximately 4’ long, and a brass cap set on the rebar.

9. In sensitive clay areas install a Type B monument as defined in EM 1110-1-1002. When the site geology is known to consist of sensitive clays, the Type B rod mark should be used.

The PVC sleeve should extend through the sensitive clay layer. The anchored section should be driven to refusal. When the site geology is known to consist of lacustrine clays, the Type B rod mark should be used. The PVC sleeve should extend through the highly desiccated soil.
