3.3 Project Site

3.3.1 AMARG Hangar. The AMARG Hangar site is located south of Irvington Road, adjacent to the existing AMARG wash rack and north of building 7420.

The proposed site is undeveloped. An existing underground water line, an 8-inch sanitary sewer line and a storm water swale occupy the site. These utilities and site features run in the north/south direction. An existing underground electrical line and gas line are located in close proximity to the proposed site. A tow-way exists east and north of the proposed AMARG hangar site. Aircrafts are towed along this tow-way to and from the existing wash-rack adjacent to the AMARG hangar site. A C-5 aircraft, with a wing span of approximately 223’, is the largest aircraft towed along this tow-way.

This project shall include the delineation of the C-5’s minimum horizontal clearance from the tow-way to ensure new site features are sited in accordance with UFC 3-260-01 unless otherwise noted. Refer to sheet C-102, Conceptual Site Plan, in the appendices and the ELECTRICAL DESIGN section for additional site information.

3.3.2 POV Parking. This project will include the design/construction of a POV parking area to be sited adjacent to the existing parking area which services building 7708. The site is located at the intersection of Irvington Road and Wickenberg Street. This site is primarily undeveloped. An existing generator facility, identified as building 7610, and an underground water line exist within the site. Building 7610 shall be relocated as part of this project. Refer to sheet C102, CONCEPTUAL SITE PLAN, in the appendices for the preferred relocation site. See also ELECTRICAL DESIGN section for additional relocation requirements. The proposed POV parking area site is currently only accessible from the existing parking area east of the site.

3.4 Project Site Survey. See sheet C103, EXISTING SITE PLAN, for available survey data. The survey data provided shall be used to assist in the preliminary design phase. The successful Proposer/Offerer shall obtain a current site survey for final design that shall include but not be limited to: the topography of the site in one foot contour intervals and spot elevations; surface features including parking lots, driveways, walks, curb and gutter, pads, walls, signs, hydrants, valves, manholes, cleanouts, inlets, utility poles, guy wires, transformers, sprinklers, backflow devices, landscaping, etc; and underground utilities. Utility locations shall be determined from base mapping, surface features found in the field and pot-hole operations. The Contractor shall field survey all sanitary sewer manholes and inlets off the site to determine the rim and invert elevations and any other utility features needed for the design/construction of this project. The survey shall encompass all areas associated with the design and

01 10 10-7 construction of all features included within the scope of the project.

Topographic map data shall be gathered by field methods, using Global Positioning System (GPS), total station methods, or a combination thereof.

The survey shall comply with EM 1110-1-1005. It is the responsibility of the contractor to obtain additional mapping from the base if needed and to verify the existence of utilities at the site.

3.5 Site Demolition. Demolition sites shall be cleared as indicated in this section. Rubble and debris resulting from the demolition process shall be removed from the site. Uncontaminated soil waste may be disposed of on Base at the location identified on sheet C101, PROJECT LOCATION MAP, VICINITY MAP, AND BENCH MARK DATA in the appendices. See also paragraph, Waste Area, below for additional information. Holes or depressions in the ground resulting from demolition operations shall be filled with satisfactory materials, compacted and graded in accordance with specification section 31- 00-00 EARTHWORK, included in the GEOTECHNICAL DESIGN section of this report.

Trees shall not be removed unless required to accommodate new construction.

Items to remain or to be salvaged (for the government), which are damaged by the Contractor during the construction/salvation process, shall be replaced/repaired in kind at the Contractor’s expense. When removing existing pavement, the Contractor shall assume that six inches of concrete is located under all existing utility patches.

3.5.1 Buildings 7410, 7411, 7412, 7413, 7416 Demolition. This project shall include the demolition of Buildings 7410, 7411, 7412, 7413 and 7416. Refer to sheet C102, CONCEPTUAL SITE PLAN, in the appendices for building locations. As-built information has also been provided in the appendices.

Buildings shall be completely demolished to include building foundations, and utility service lines back to the main, if feasible, or at minimum 5 feet from the buildings footprint. All existing fire hydrants in the vicinity shall remain functional during and after demolition operations. Sidewalks from the buildings entrances shall also be demolished and terminated back at the main pedestrian sidewalk. Buildings shall be demolished after the tenants have re-located to the new facility and are fully operational.

3.5.2 Hangar Access/Tug Road Demolition. Existing asphalt pavement exists adjacent to the parking apron. The asphalt shall be demolished to accommodate the hangar access apron and the tug roads where they intersect the existing parking apron.

3.6 Utility Relocations. The 8-inch sanitary sewer line, storm water swale and associated appurtenances, which currently occupy the AMARG Hangar site, shall be relocated as necessary to construct the AMARG Hangar and associated site features. Utilities shall not remain beneath the AMARG Hanger footprint. Abandoned utilities shall be demolished and capped at the main.

The existing water line located within the POV parking area site shall be relocated as necessary to construct the POV parking area. Refer to the ELECTRICAL DESIGN section for demolition of existing communication and electrical items. The Contractor shall also relocate any/all existing utility lines and associated appurtenances, which will not have adequate cover due to new project grades, as required to achieve proper cover. It is the contractor’s responsibility to determine the below grade depths of

01 10 10-8 existing utility lines within all areas of new project construction.

Features demolished within the project site, including utilities, shall be removed from the site and disposed of off Base. The Contractor is responsible for acquiring all necessary permits prior to waste disposal.
