The contractor shall remove existing copper piping, piping insulation, isolation valves, safeties, conduit, wiring that are externally connected to the existing demolished equipment, any of the copper piping, piping insulation, isolation valves, safeties, conduit, wiring more than 2 feet underground may be abandoned, but all penetrations must be removed down to the 2 foot mark.

2.0 PROJECT OBJECTIVES

(a) Contractor shall ensure they will use an A&E firm to design and provide the government with engineered drawings that shall capture each new air‐cooled chiller, transformer, distribution panels, cabling chilled/heating water pumps, chilled/hot water piping and all other equipment that is associated with the existing HVAC systems, blowdowns, concrete housekeeping pads and all other components that are associated with each piece of new equipment.

2.2 SUSTAINABLE DESIGN

Design and construct project per sustainability requirements identified in Section 01 33 29.05 20, Sustainability Reporting for Design-Build. Additional specific sustainability requirements are found in this document.

2.3 STORMWATER MANAGMENT - LOW IMPACT DEVELOPMENT

(LID)

Provide a design that incorporates low impact development strategies complying with UFC 3-210- 10, Low Impact Development. For Navy and Marine Corps projects, comply with Navy LID Policy (commonly referred to as the Penn Memo). The Navy LID policy sets a goal of no net increase in storm water and sediment or nutrient loading from major renovation projects and construction projects. Major renovation projects are defined as having a storm water component and exceeding $5 million and major construction projects are defined as exceeding $750,000.

If the project footprint exceeds 5000 SF (464.5 SM) and does not maintain the predevelopment hydrology to the maximum extent technically feasible (METF), these constraints must be documented on the NAVFAC LID Data Card (NLDC) and approved by the Government's civil reviewer. The NLDC can be found at:

http://www.wbdg.org/pdfs/NAVFAC_LID_Data_Card_v2.0.pdf . If LID is not implemented to the METF as defined in UFC 3-210-10, Low Impact Development, a waiver must be obtained from the Regional Engineer. Coordinate waiver review and approval with civil Technical Discipline Coordinator (TDC). LID Waiver Form can be found at:

http://www.wbdg.org/docs/NAVFAC_LID_Waiver_Form_v3.doc .

These policies are in addition to State or Local storm water management program permit requirements. The DOR must balance all applicable requirements, Federal, State, Local and the above stated policies, and acquire required regulatory permits when managing storm water generated.

2.4 CYBERSECURITY

All control systems (including systems separate from an energy management control system) must be designed, acquired, and executed in accordance with DoD Instruction 8500.01, DoD Instruction 8510.01, and as required by individual Facilities Engineering Command (FEC) or installation implementation policy.
