EROS Science Center Design / Build

Dual Cool CRACs Units

STATEMENT OF WORK

Introduction

The Department of Interior, USGS/Earth Resources Observation and Science (EROS) Center, Sioux Falls, South Dakota is seeking firms to Design/Build new Computer Room Air Conditioning (CRAC) units at the Mundt Federal Building, located at the EROS Science Center, 47914 252nd Street, Sioux Falls SD 57198.

EROS data center has computer room air conditioner (CRAC) units and these units need to be replaced due to age. Some units are chilled water only and some are dual-cool units with compressors. EROS data center will be installing dual-cooled type CRAC units with chilled water as primary source of cooling with backup compressors to eliminate the need for a computer room outage during rare service times. The installation and startup of the CRAC units will be completed by the contractor furnishing the CRAC units.

Scope Contractor shall perform all work in accordance with the specifications, drawings, and all applicable Federal, State, and local regulations. Drawings will be given to parties after attending the site-visit and filing paperwork with the Contracting Officer for release of documents.

This SOW includes:

Section 1 – General Requirements Attachment A – Project Drawings Attachment B – Basis of Design.

Site visits shall be at the request of the COR to inspect work installed by the contractor, to resolve issues, review the status of in-progress as-built drawings and for other reasons deemed necessary. At a minimum 2 visits will be required during construction. One, when the contractor mobilizes and has presented plan for dust control and dust control plan is completed and when the final walk through inspection is scheduled.

E. Record drawings: Upon completion of construction, provide (2) sets of stamped

"Architectural E1" (30"x42") as built drawings, as well as in AutoCAD and PDF formats.
