Provide a UPS to enable (all) hangar door operation during a power outage. Provide new above-slab plumbing. The new large hangar space will be able to house 10 aircraft at a time. Other new interior spaces include: an addition to the Northwest corner to include the fire suppression system and a storage room. The existing “wing” extending from the northwest building face shall enclose electrical and mechanical rooms, a communications room, two storage rooms and office spaces as described.

All borings shall be sampled by a split spoon sampler in accordance with ASTM D-1586, with samples visually classified at 2.5 foot intervals to a depth of 10 feet and at 5 foot intervals thereafter in accordance with the Unified Soil Classification System (ASTM D-2487). The depth to water (if encountered) shall be recorded on the boring logs. Under buildings, borings shall extend to the depth of 50 feet or refusal, and under roads and/or parking areas, to a depth of 10 feet. Soil borings shall be abandoned in accordance with the following:

With the exception of main storm drain culverts, placing utilities and culverts under existing roads shall be by jack and bore unless otherwise approved by the CMI. All sanitary sewer, storm water, water supply, gas, and electrical construction shall comply with local and Base requirements. Contractor shall obtain all required Base, City, County and State digging, installation and operation permits prior to any excavation. Obtain CMI approval at least 10-days prior to any utility outages. Obtain CO approval not less than 72-hours prior to any utility outages. Relocate utilities or equipment so as to minimize the impact on existing facilities. No physical connections shall exist between sewer and water supply systems. Unless otherwise required by local utilities:

a. Separate sewer and water lines by min. 10 feet horizontally; except if the bottom of the water pipe is min. 12 inches above the top of the sewer; min. horizontal spacing may be six (6) feet.

b. Encase a sewer line crossing over a water line in concrete 10 feet on each side of crossing.

c. Place pipes at least three (3) feet underground where possible to protect pipe from superimposed live loads of ordinary traffic. Depth may be greater if required by local codes and agencies.

2) Connections: Contractor shall provide all utilities; including water, sewer, phone, power, and gas; required to make the hangar fully functional. Pipe water to the HEFFSS in Hangar 456: either from Building 441 (Pump house) or from Hangar 450. Obtain prior CMI approval of all new-to-existing utility connections. If any such connections are later discovered not to have been observed by the CMI, the CMI may require the Contractor at no additional cost to the government to disconnect and reconnect the utility under CMI observation.

3) Device Location: Locate backflow prevention valves, post indicator valves, transformers, electric switches, telephone and cable boxes, manholes, etc., to be concealed from building occupants and personnel passing by the site. New utility lines shall not be located within five feet of the footprint of any known future facility.

Materials )Marking Utility Lines: Bury continuous tape 12 inches above all underground utility lines to identify the type of pipe buried beneath. Use tape specifically manufactured for marking underground utilities. Use plastic tape to identify metallic pipe and metallic tape, detectable by electronic instruments, to identify non-metallic pipes.

5) Metering: Meter all utilities to each facility. For Government owned utilities, install meters that are wireless data transmission capable as well as have a continuous manual reading option. All meters will be capable of at least hourly data logging and transmission and provide consumption data for gas, water, and electricity. All meters shall be able to communicate with the base utility monitoring control service. Gas and electric meters will also provide demand readings based on consumption over a maximum of any 15 minute period. Configure all meters to transmit at least daily even if no receiver

for the data is currently available at the time of project acceptance. For privatized utilities, coordinate with the privatization utilities for the proper meter base and meter installation.

6) Road Crossings: Roads and driveways shall not be crossed by open cut unless approved by the CI. If the open cut method is performed, one lane of the street shall remain open to traffic at all times. Contractor shall provide steel matting sufficient to carry traffic loading over the excavated area. Utility structures shall be designed to accommodate the traffic loadings for the area in which the structures are placed. Requests for lane closures for open cuts shall be made in writing prior to commencement of work within a number of calendar days to be determined by Base.

7) Excavations: All excavations, trenches, open manholes, etc., will be properly shored, braced, barricaded or guarded. Contractor shall provide barricades and maintain warning lights or other illumination from sunset to sunup at all excavations that are adjacent to pedestrian or vehicle thoroughfares or as directed by the CMI.

8) Safety: Contractor shall enter manholes, tunnels, tanks, or other confined spaces only if compliant with OSHA pre-entry requirements and after obtaining confined space entry permit(s) from the government.

E. Permits: Permits required include the items listed within this section. Contractor shall obtain and bear all costs of permits required for this project.

1) Storm water Management Permit: A storm water Management permit is not required for this project per Mississippi Department of Environmental Quality.

2) Sanitary Sewer Permit: A sanitary Sewer Permit is not required for this project.

3) National Pollutant Discharge Elimination Systems (NPDES) Permit: is not required for this project because the of site disturbance area is less than one acre

4) Drinking Water Permit: A drinking water permit is not required for this project F. Storm Drainage System and Management:

1) Design: The Contractor shall design and construct additions to the existing storm drainage system as needed. This system shall be designed and constructed to, but may not necessarily be limited to, the items listed within this section. The Contractor shall evaluate the flow of storm water runoff to and from the site and insure that the flow of water will be properly moved from the site to the storm water sewer system. The drainage system shall tie to the existing system along Imes Street.

The storm drainage system pipe shall be designed for the anticipated traffic loadings. Profiles shall be required for the underground storm drainage systems.

2) Layout: Design the drainage system layout to best meet the facility drainage requirements. All low points in grade shall have an inlet as to avoid ponding water. The system shall take into consideration topography, ultimate development of drainage area, possible future extension, outfall locations, and coordination with existing drainage systems and other existing or future underground utilities.

3) Street Drainage: Street drainage shall be accomplished by the use of curb and gutter and curb inlets. Curb gaps will be considered in areas where roadside ditches are used. The center one-third of the street should not convey runoff during the passing of the design storm. Inverted crown sections for the streets shall not be used without prior approval. Curb inlets should not be located in the radius of street intersections, at curb returns, or where pedestrian traffic is most likely to occur.

4) Stormwater Manholes: Storm water manholes shall be provided at junctions of gravity pipes and at each change in pipe direction, size or slope. Manholes shall be located in areas that are readily accessible for operation and maintenance purposes. A steel ladder shall be provided where the depth of a manhole exceeds 12 feet. Manhole covers shall be level with pavement or two (2) inches about grade in grassy areas, and shall be cast iron and have the word “STORM” marked on them.
