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 housing unit on the site of the de-activated Nellis Federal Prison within Area II. The size of the site is approximately 62,000 square feet. A shared parking area for Building 10203 and adjacent buildings exists across the Seymour Johnson Avenue from the proposed site to meet the minimum 40 parking space requirement from Table 20.2 of AFH 32-1084 (60% of occupancy).

An on-site renovation investigation report indicates that asbestos is not expected to be encountered on site, but lead may be present to an extent in some of the building materials

TSOW Page 4 of 53 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 ramps up to a higher elevation than the entrances in the main wing. Emergency exit elevations are at the higher interior elevation. In the existing condition, drainage is accomplished through a combination of overland surface flow to Seymour Johnson 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. Two stairwells, located on the east and west sides, exist below natural grade for emergency exit access from the building basement.

Existing grades are generally sloped away from these areas to prevent collection of runoff.

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 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. An existing 10-inch cast iron main is located in the landscaped area between Seymour Johnson Avenue and the building. This line will be replaced in the future along with the entire Area II water system, per design plans by Jacobs from February 2010. An existing 2.5-inch service lateral enters the building through the north side, slightly to the west of the building center, running perpendicular to the street. 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 (plans by Jacobs, February 2010), the fire and domestic water services will be provided through separate distribution mains. Two existing 6-inch service laterals enter the building through the front into the basement. The westernmost service lateral is currently capped inside the building and not used. The easternmost service lateral is connected to the existing fire suppression system. A Fire Department connection exists at ground level outside the building at this location. 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 1,700 gpm of flow is available to the main with a system residual pressure of 20 psi. Based upon system modeling results from the Area II water system reconstruction design, Subsequent to the replacement of the Area II

TSOW Page 5 of 53 water system, the available fire flow subsequent to line replacement will be approximately 3,400 gpm with 20 psi residual system pressure.

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 discharged through a 6-inch lateral to the Nellis AFB sewer system. An existing 8-inch sanitary sewer main runs parallel to Seymour Johnson Avenue in the landscaped area between the street and the building. External cleanouts are not present within the existing system.

3.2.1.1.4 Main Electrical Feed. The main building feed runs underground into the building at the west side near the front of the building. The electrical service enters in the building basement, and connects to the main building power panels, located on both sides of the basement. The power feed runs inside the building between the panel locations.

3.2.1.1.5 Natural Gas Supply. Natural Gas to the building is provided through a 1-inch service with a 2-inch pressure regulator, which connect to a gas main running behind the building.

3.2.1.1.6 Communications. An existing communications system is provided to the building, although the extent of the system is unknown to base personnel. A telecommunications riser box is located on the southwest corner of the buildings west wing.
