Statement of Work Repair and Renovate Bldg. B517 Software Maintenance Facility Hill AFB, UT

Scope of Work The work for this project is to design and renovate Building 517. The final product shall be equivalent to Building 518, post renovation, except site specific conditions and the facility shall comply with Air Force Sustainable Design and Development (SDD) Implementing Guidance, 2 Jun 2011. The drawings and specifications for building 518 will be provided, but the contractor shall modify this design to comply with site specific conditions of Building 517 and to comply with Air Force SDD Implementing Guidance. The Government will demolish the existing interior of the building so that only shell of the building remains, however, minor quantities of lead based paint and asbestos may still be present that the contractor shall manage on a case by case basis in accordance with the General Requirements. This Task Order is to provide a complete renovation of the building including architectural, structural including seismic, mechanical including plumbing, HVAC and fire protection, force protection including progressive collapse and electrical including communication system improvements throughout the building. Building 517 has three floors including a one level mechanical room. The remodeling shall include the addition of a main entry and elevator with stops at all three floors. Restrooms shall be added to all three floors. The HVAC system shall be by a Ground Source Heat Pump (GSHP) and a new Fire sprinkler system shall be added. The structure shall have the windows and doors designed for blast protection including progressive collapse.

Task Order Description The Contractor shall provide all labor, material, and equipment necessary to execute and complete the subject project. General work requirements for each discipline are detailed in Specification Section 01 11 01 General Requirements of Division 1 documents. Contractor shall perform design and construction work as stated in Division 1 through Division 33 of the Technical Specifications, drawings, and all other documents contained in the RFP.

In addition to the design and construction already stated above, the Contractor shall submit the following for each discipline identified below:

Concrete Work: 1) Detail of handicapped ramps 2) Concrete joint layout, including any epoxy, dowels, construction joint, control joint, expansion joint material 3) Detail or specification for crushed concrete referenced on sheet AE-407 4) Detail showing jointing pattern for the new PCC driveway.

Electrical Work: 1) Detail for ground rod installation depth from below grade, ground rod size, and exothermic welding 2) Detail for grounding of transformer pads 3) Detail showing size of grounding conductors 3) Detail showing size of fused disconnect for WH-1.

Mechanical Work: GSHP – 1) Detail showing boring locations for well field. 2) Detail drawing showing diameter of bore hole required for loop section, with clearance shown between bottom of hole and bottom of loop. 3) Detail showing material to fill space between the side of the hole and loop material. 4) Detail showing top of hole 5) Detail of section showing rock locations that drill may impact in the 400’ depth. Installer for GSHP shall be accredited by International Ground Source Heat Pump Association (IGSHPA).
