Attachment 1: Statement of Work EROS Chilled and Condenser Water Piping Rev 1 0002

EROS Data Center
Removal and Replacement of Chilled and Condenser Water Piping STATEMENT OF WORK

The Department of Interior, USGS/Earth Resources Observation and Science (EROS) Center, Sioux Falls, South Dakota is seeking professional firms to provide construction to remove and replace chilled water piping and condenser water piping which serves the 1996 building addition at EROS. Location is the USGS/EROS Science Center, 47914 252nd Street, Sioux Falls SD 57198.

BACKGROUND

A 2018 study of the cooling towers, chillers, condenser water piping, and chilled water piping in the 1996 EROS building addition identified items in extremely poor condition. A design to upgrade the system was completed as a result on 6/12/2020 titled Earth Resources Observation and Science Center Phase 1: EROS Fluid Coolers Design Services (Attachment 2). The 6/12/2020 as built drawings are included in Attachment 3 along with the mechanical system design criteria (Attachment 4). Due to cost constraints, the design, drawings and mechanical design attachments are provided for reference and basis of design only. Removal and replacement of cooling towers have been completed. The third chiller will not be completed under this contract. Solicitors may provide clearly defined design variations provided solicitors also clearly demonstrate operational and/or construction cost savings.

SCOPE OF WORK

Construction Scope/Objectives: The project objectives of the USGS are as follows: All aspects of the project shall keep the facility offices and computer rooms operational. Minimal impact to the conditioned spaces may be allowed and as such, project must be completed in phases.

The specifications and drawings provided as Attachments 2–4 are furnished solely as Basis of Design reference documents to illustrate prior design intent and existing conditions. Only the requirements specifically identified in this Statement of Work constitute the contractually binding scope. Any elements shown in the reference documents but not described in this SOW shall not be considered part of the contract. Construction may not have precisely followed the design, so no assumptions should be made on existing site conditions based on the previous recommendations. The specifications have been revised to remove references to the “architect” and clarify that the Contracting Officer Representative (COR) will perform this function. Removal and replacement of cooling towers have been completed. The third chiller will not be completed under this contract.
