1-1.2 Scope of Work Description

General Information: This work is to replace the chiller systems as described in the following paragraphs. The Contractor is responsible for installing a chiller system that constitutes a complete and usable system. A complete and usable system includes but is not limited to what is covered in statement of work. Temporary mobile chiller systems will be required to cover outage periods that take place between 1

April and 30 November. Recommissioning is a requirement for all chiller locations per the commissioning specification Division 01 91

00.15. No Direct Digital Control (DDC) connection to a building automation system or installation energy management and control system is required for any location.

The current chillers use R-22 refrigerant and the intent of this Scope of Work (SOW) is to have the chillers replaced with chillers that use

R-410A refrigerant.

Finished surfaces of patched area shall be flush with the adjacent existing surface and shall match the existing adjacent surface as closely as possible as to texture and finish.

b. Unforeseen Hazard: Notify the Contracting Officer of any unforeseen hazard or unforeseen site condition during work.

1-1.4 Environmental Consideration and Mitigation Requirements

Hazardous materials are assumed as present and as part of this contract, including without limitations, asbestos in all wire and pipe insulation and lead based paint in all layers of paint, including under top coat. The Contractor is required to test for the presence of asbestos and lead paint on any suspected hazardous materials being disturbed and notify the Contracting Officer immediately if found. The asbestos and lead containing materials shall be removed and disposed of in accordance with the Japan Environmental Governing Standards
