http://www.ccb.org/docs/ufgshome/UFGSToc.html. Unless noted otherwise, material specifications, equipment efficiencies, equipment listing (i.e., UL, ANSI, NEMA, etc.), testing requirements, execution, and similar requirements shall not be changed unless dictated by more stringent requirements referenced in this RFP.

3.1.2.1 Provide Government an informational copy of the completed specifications, design calculations, and drawings.

3.1.3 The Contractor is responsible for field verifying all information given. The Contractor is also responsible for obtaining all information necessary to properly design and install all work. Gathering information during design shall be coordinated through the Contracting Officer. Any survey required to provide utility locations, manhole inverts, verification of existing features, etc., shall be the responsibility of the Contractor and shall tie into the project datum.

3.2 Site

3.2.1 Site Layout. The existing building site is shown on Drawing Sheet C-002 – Site Plan. The modifications to the site shall meet the minimum provisions of all applicable references sited in these RFP documents. The Contractor shall minimize construction impact and confine proposed development to the project area as designated in these RFP documents.

The building is a former auditorium on the site of the de-activated Nellis Federal Prison within Area II. The size of the site is approximately 18,800 square feet. A shared parking area for Building 10204 and adjacent buildings exists across the Seymour Johnson Avenue from the proposed site and additional parking spaces exist across Fairchild Avenue to meet the minimum 112 parking space requirement from Table 20.2 of AFH 32-1084 (60% of occupancy).

An on-site renovation investigation report indicates that asbestos and lead may be present to an extent in some of the building materials used on site. The contractor is responsible for determining the necessary Personal Protective Equipment and reviewing any environmental studies and reports completed at the time this RFP is issued.

General site topography contours have been provided based upon an aerial topography, however, additional topographic survey is required to verify site specific details and finished floor elevations that were not provided by the aerial survey.

The site generally slopes to the west. The building foundation appears to be at a single elevation, although the interior floor slopes in theatre style. In the existing condition, TSOW Page 4 of 40 drainage is accomplished through a combination of overland surface flow to Seymour Johnson Avenue and Fairchild Avenue and infiltration through the xeriscaping. Existing ground is generally sloped away from the building for varying distances prior to draining overland to the west to protect the building from flooding. However, a low point exists in the southeast corner of the building, where water collects on the ground. The site does not appear to accept quantifiable runoff from adjacent sites, or upstream discharges.

There are no existing storm drains within the vicinity of the area.

3.2.1.1 Existing Utilities. Existing utilities serving the building are shown on Drawing Sheet C-002 – Site Plan. Contractor is to verify location, presence, condition, and capacity of adjacent mains and existing laterals and make any sizing adjustments as necessary.

3.2.1.1.1 Domestic Water. The water supply for the building is provided by the overall base water distribution system. The Area II portion of the water system is pressurized through the use of an elevated tank. Existing 10-inch cast iron mains are located in the landscaped area between Seymour Johnson Avenue and the building and between Fairchild Avenue and the building. These lines will be replaced in the future along with the entire Area II water system, per design plans by Jacobs. from February 2010. An existing 1-inch service lateral connects to the main perpendicular to Fairchild Avenue, makes a 90-degree turn, and enters the building through the north side. Currently, there is no evidence of the existence of any backflow prevention device or water meter. An existing Nellis water system model, prepared in 2008 by EarthTech Inc., indicates that the static water pressure will exceed 90 psi at the main.

3.2.1.1.2 Fire Suppression Water. The fire suppression supply for the building is also provided by the overall base water distribution system. With the replacement of the Area II water system, the fire and domestic water services will be provided through separate distribution mains. An existing 6-inch service lateral enters the building through the southeast corner into the fire riser room. A Fire Department connection exists at ground level outside the building at this on the east side of the corner. Currently, there is no evidence of the existence of an operational Position Indicating Valve for the fire service.

The existing Nellis water system model, prepared in 2008 by EarthTech Inc., indicates that the static water pressure will exceed 90 psi at the main, and approximately 1,675 gpm of flow is available to the main with a system residual pressure of 20 psi.

3.2.1.1.3 Sanitary Sewer System. The waste water from the sanitary fixtures and existing floor drains are collected by sewer pipes within the building and discharge through two 4-inch laterals to the Nellis AFB sewer system. Existing 8-inch sanitary sewer mains run parallel to both Seymour Johnson Avenue and Fairchild Avenue in the landscaped area between the street and the building. This building drains to the sewer parallel to Fairchild Avenue. External cleanouts are not present within the existing system.

3.2.1.1.4 Main Electrical Feed. The main building feed is an overhead drop feed from an overhead transformer across Fairchild Avenue.
