DESIGN/BUILD HVAC SYSTEM BLDG 133 LUKE AFB, AZ

1. Introduction: This Statement of Work (SOW) sets forth basic requirements for Project NUEX 09-1408, Work Order# 81825, to repair HVAC Building 133. This design- build project will require performance at Luke Air Force Base, Arizona. This project will be an upgrade to the existing HVAC system in Bldg 133. 2. Scope: The existing HVAC system in Bldg 133 consists of Pumps, Chiller, Piping, Heating and Domestic Hot Water Boilers, and 2 (ea) Hot Water Storage Tanks, to include all accessories. The existing Cooling Tower, Plate and Frame Heat Exchanger, and Condenser pump were replaced in March 2011, and will be part of the project to re-connect. The existing mechanical system will require inspection to identify the extent of the current deficiencies (i.e., investigatory phase). Additionally, the construction and repairs to remedy existing deficiencies are requirements of this contract. It must be acknowledged by the contractor that the work scope includes complete review of the mechanical rooms, preliminary documents, validation of the preliminary work and standards referenced, and identification of deficiencies against present day standards for an Air Force and DoD facility. Under this contract, the contractor may be tasked with validating construction price/cost and scheduling. The contractor will complete project design to 100% and then go on to complete the construction. Construction may begin after approval of the 65% design. Contractor will deliver and warrant the equipment and materials replaced. The objective of this project is to deliver a complete and usable mechanical system, such that it supports the present day mission and meets present day standards. This project work will include all demolition, disposal, material, labor, and testing to deliver complete, operational, and usable systems. 2.1 Minimum Replacement/Repair items: Additional items may be required based on investigatory design. 2.2 The work will include the following, with a performance period of 180 calendar days after issuance of a written Notice to Proceed, but not necessarily be limited to: 2.2.1 Demolition: Provide the Government a list of equipment to be demo and disposed to determine what the Government will keep. All other materials will be the contractor's responsibility to disposed. Refrigerant from machinery shall be recovered and returned to the Government. 2.2.2 Replace existing chiller with appropriate type and size based on investigatory study (use screw type compressor for increased efficiency) 2.2.3 Remove and replace existing pumps for entire HVAC/R system 2.2.4 Provide VFDs where they are needed 2.2.5 Evaluate current electrical system and upgrade if this existing is not compatible with new HVAC components 2.2.6 Replace existing heating boiler with appropriate type and size based on investigatory study 2.2.7 Replace existing domestic hot water boiler with appropriate type and size based on investigatory study 2.2.8 Replace existing hot water storage tanks to include all accessories with appropriate type and size based on investigatory study 2.2.9 Replace current EMCS to improve efficiency 2.2.10 The contractor will provide complete test and balance of applicable equipment to serve as a basis for acceptance of the replaced/repaired installation 2.2.11 The contractor will provide training, and a complete operations and maintenance package, for the future operation of the upgraded HVAC system. 2.2.12 Possible Asbestos, contractor will have a thorough inspection performed and given to the government (56th CES/CEAN) prior to any work beginning. 2.3 Design Services: During the design phase of the project, the contractor will utilize a professional consultant, herein after referred to as the A/E. The A/E is responsible for the development of the design deliverables. Specifically, the effort will result in documents that are the basis for the design and construction efforts under this contract. This effort necessarily includes development of a design basis (to include applicable codes, standards, and guidance) and outline specifications. The contractor will complete the design documents incorporated by reference below. Investigatory phase: The contractor shall visit the job site to re-verify location, conditions, quantities and dimensions previously determined during the design portion of the project, as part of his construction proposal preparation.

Drawings and as-builts will be delivered as AutoCAD and PDF formats. The final records, test reports, to include O&M manuals, shall be in PDF formats, as finalized with personnel in Engineering at Luke Air Force Base. The contractor is responsible for construction quality on the project. The contractor is required to make their own field investigations to verify dimensions and other information shown on Government furnished reference drawings. Coordination between the (A-E) design disciplines in production of the contract drawings is the contractor's responsibility. 2.5 Summary Status Reports: The contractor shall provide weekly and monthly progress reports for this contract. All information will be maintained in an electronic database (compatible with Microsoft Office Professional, current version) to facilitate summary retrievals.
