B 10 Modernization - Statement of Work

June 6, 2025 Statement of Work B10 Modernization Centers for Disease Control and Prevention (CDC) Roybal Campus 1600 Clifton Road Atlanta GA 30329

CDC Project Number P20210098

I. PROJECT DESCRIPTION

A. GENERAL & PLACE OF PERFORMANCE: This scope of work details the design and construction services provided by the design build contract for the modernization of B10 1600 Clifton Road, Atlanta GA also referred to as the Roybal Campus. The Design Build contractor shall provide all the services and furnish all the materials required for both the design and construction of modernization of the B10 central plant for the Roybal campus.

B. BASELINE SECURITY REQUIREMENTS: All physical access will be coordinated through the safety and security office. This process includes badging each individual requiring routine access with a smart card. These badged individuals will only have access to the area work will be taking place. The general contractor’s representative will be present at all times work will be taking place. Any non-badged personnel will be limited to access 5 days in any 365 day period as allowed by the safety and security office.

C. PROJECT BACKGROUND & PURPOSE: Building 10 on the Roybal campus is outdated and in need of repairs and improvements to maintain reliability for serving campus needs.

Chillers 1-4 in the plant are at the end of their useful lifespan. Associated equipment with the chillers including cooling towers, pumps and other appurtenances are also at the end of their useful lifespan. As the campus continues to be developed, the central plant will be required to provide additional capacity to serve the campus needs. The current electrical system has been adjusted to meet the changing needs of the plant and does not conform with the best practices and CDC standards. Lastly, we are currently paying sewer fees for make-up water used in the central plant and this project shall include all necessary work and devices to monitor this water usage such that a sewer credit is available to CDC.

E. EXECUTIVE SUMMARY:

CHILLED WATER IMPROVEMENTS:

Four existing 1,450 ton chillers will be replaced with new 1,800 ton chillers. Nine cooling towers will be replaced with eight new cooling towers. Four Primary chilled water pumps

CDC P20210098 01 01 11- 2

Section 508 also requires that individuals with disabilities, who are members of the public seeking information or services from a Federal agency, have access to and use of information and data that is comparable to that provided to the public who are not individuals with disabilities, unless an undue burden would be imposed on the agency.

In order to facilitate the Government's determination whether proposed EIT supplies meet applicable Section 508 accessibility standards, offerors must submit an HHS Section 508 Product Assessment Template, in accordance with its completion instructions. The purpose of the template is to assist HHS acquisition and program officials in determining whether proposed EIT supplies conform to applicable Section 508 accessibility standards. The template allows offerors or developers to self-evaluate their supplies and documentation detail - whether they conform to a specific Section 508 accessibility standard, and any underway remediation efforts addressing conformance issues. Instructions for preparing the HHS Section 508 Evaluation Template are available under Section 508 policy on the HHS Web site http://hhs.gov/web/508.

(d) Respondents to this solicitation must identify any exception to Section 508 requirements. If a offeror claims its supplies or services meet applicable Section 508 accessibility standards, and it is later determined by the Government, i.e., after award of a contract or order, that supplies or services delivered do not conform to the accessibility standards, remediation of the supplies or services to the level of conformance specified in the contract will be the responsibility of the Contractor at its expense.

(e) Electronic content must be accessible to HHS acceptance criteria. Checklist for various formats is available at http://508.hhs.gov/, or from the Section 508 Coordinator listed at https://www.hhs.gov/web/section-508/additional-resources/section-508-contacts/index.html.
