10. DESCRIPTION OF PROPOSED CONSTRUCTION: Construct 30 MW technical load data center to include modular structural components, finished flooring (both raised and administrative), ceiling, lighting, electrical, generators and associated air pollution control systems, mechanical, ventilation, and fire suppression. Also, these funds will provide utilities to include building electrical service, chilled water systems, communications, water, sanitary sewer and storm water management. Installed infrastructure will support 65MW technical load data center capacity for future expandability. The design is to be capable of Tier 3 reliability. Power density will be appropriate for current state-of-the- art high-performance computing devices and associated hardware architecture. U.S. Government and local support services will be provided. Security measures for this project include, but are not limited to a Visitor Control Center provided for data center personnel which is separate from the interim Visitor Control Center for construction personnel; perimeter security; and access control facilities. Physical and technical security of the construction site will be assured. This project will be designed in accordance with the Uniform Federal Accessibility Standards (UFAS)/Americans with Disabilities Act (ADA) Accessibility Guidelines, Antiterrorism Force Protection (ATFP) standards and Unified Facilities Criteria (UFC) design standards.

11. REQUIREMENT: 30 MW ADEQUATE: None SUBSTANDARD: None
PROJECT: Construct a 30 MW technical load data center and infrastructure for 65MW technical load data center capacity.
REQUIREMENT: This project is required to provide a 30MW technical load data center and infrastructure for 65MW technical load
data center capacity to support mission. The project will include the following:
(1) Site
(a) Facility design goal will be to the highest LEED standard attainable within available resources and will include: sustainable site
characteristics, water and energy efficiency, materials and resources criteria, and indoor environmental quality.
(b) Mechanical and electrical plants are to be housed in separate structures to prevent transfer of noise and vibrations to the data
centers
(2) Facilities
(a) Data center technical load of 30 MW distributed across raised floor are the design parameters for the facility.
(b) The infrastructure support and administrative areas will be designed to support state-of-the-art high-performance computing
devices and associated hardware architecture.
(c) Slab floor loading of approximately 1500 pounds per square foot (PSF)
(d) Enhancements to the building for IT and security include construction as a sensitive compartmented information facility (SCIF),
as well as, requirements related to Antiterrorism Force Protection (ATFP).
(3) Structural
(a) Technical load will be distributed across the data center areas.
(b) Seismic considerations are to be made in the facility design.
(c) Data center areas are to have depressed concrete slab construction with a load bearing capacity of 1500 pounds per square foot
(PSF).
(d) Facility command and control contained in a central modular office component.
(e) Facility will have a loading dock with vehicle bays, three (3) of which are to be equipped with dock levelers sized to handle
tractor trailers.
(4) Electrical
(a) Technical load capacity is 30 MW with loads distributed evenly across the data center areas.
(b) Supervisory Control and Data Acquisition (SCADA) to either PDU level or distribution panel level if required
(c) Dedicated substation for each critical UPS.
(d) UPS and generator backup for facility systems.
(e) Generators will include Selective Catalytic Reduction (SCR) pollution control equipment, chemical storage tanks and feed
system.
(5) Mechanical
(a) Chilled water system to support both air and water cooled equipment.
(b) Each data center area is to have air cooled and water cooled equipment with Computer Room Air Handlers (CRAHs) located
external to the raised floor area. The piping headers / systems are to be designed to accommodate future expansion.
(c) Back-up capability for mechanical equipment.
(d) Cooling Towers
(e) Air distribution redundancy for CRAHs.
(f) Fire Protection – Double interlocked pre-action fire protection system for all electrical and mechanical support spaces.
(g) Wet pipe for administrative and raised floor areas per DOD standards.
(6) Security systems
(a) Video surveillance
(b) Intrusion detection
(c) Access control system
