PART 1 - INTRODUCTION

This Design-Build Statement of Work (SOW) defines the requirements for design and construction services at March Air Reserve Base, CA (MARB). The Contractor shall furnish the personnel, services, equipment, materials, facilities, and other requirements necessary for, or incidental to, the performance of work set forth herein. Primary technical services shall be performed by individuals who are licensed members of architectural, planning, science, and engineering professions.

1.1 SCOPE

The Contractor shall provide design-build services to the 452nd Civil Engineer Division at MARB for project PDPG 160109, Provide Backup Generator and Server Room Cooling System at Building 602. This contract requires, at a minimum, field investigations, recommendations, solutions, calculations, measurements, preparation and review of design plans and specifications, and specified construction services. The Contractor shall be capable of addressing and interpreting all aspects of facility design and construction related to the project.

1.2 PURPOSE

There are two objectives for this project: 1) to provide whole building generator backup power for building 602 and 2) provide a chilled water air handler and humidity control for a critical server room within building 602. The contractor shall provide a design that meets the requirements set- forth in this Statement of Work for each of the applicable functions. This project will be completed in two phases, the Design Phase and the Construction Phase.

The Contractor shall manage and perform Design-Build work as defined in the Statement of Work. The following are typical Design-Build requirements: completion of design documents, construction, testing, start up and commissioning, construction management, scheduling, maintaining construction facilities and temporary controls, environmental protection, and project closeout. The contractor shall construct in accordance with (IAW) approved 100% design and specifications.

1.3 EXISTING CONDITIONS

General:

Building 602 was constructed in the early 1980s and contains approximately 26,000 sq. ft. of office space and 2,600 sq. ft. of mechanical areas. The facility has no backup power system.

Electrical:

Power for the building is provided by a 480/277 volt, 3 phase, 4 wire, delta/y configured transformer. The transformer is in a mechanical yard on the south side of the building. Predominant loads are HVAC, lighting, and computer systems.

The main area of the building is conditioned by a redundant set of air handlers and central duct system. The interior mechanical spaces are conditioned by a single air handler. The air handlers are located within the mechanical/mezzanine area on the east side of the building. Cooling is provided by a chilled water system that includes a redundant set of 90 ton chiller and chilled water pumps. The pumps supply chilled water to coils within each of the air handlers. Heating is provided by reheat coils within variable-air-volume units located throughout the building.

A direct digital control (DDC) system, installed in 2008, controls the HVAC system. Server Room Cooling System:

The server room is approximately 240 square feet and is currently served by an 8 ton DX split system (Computer Room Air Conditioner) that is independent of the main HVAC system. The floor of the server room is a raised floor system elevated approximately 4 feet above the concrete slab.
