Replace Generator and Switchgear B504 & B506, Tinker Air Force Base, Oklahoma

Proposal due date extended to 20 January 2017.

Proposal due date extended to 10 January 2017.

This is a design build procurement for Tinker Air Force Base, DLA Warehouse Building 504 and Building 506. Replace the Building 506's "head end" electrical distribution system in kind with new equipment. This would include USS #1 and #2 (medium voltage switches MS-1 and MS-2 and 1500 kVA dry-type transformers) ATS #1 and #2, Main (Secondary) Switchboards MS1 and MS2, Generators B1 and B2, Generator Control Switchboard, Generator fuel system (including day tanks, underground storage tank and associated fuel lines, pumps, battery chargers and spill containment), medium voltage cable to USS #1 and #2, and busduct from the Generator Control Switchboard to ATS #1 and #2. The component replacement option would include upgrading and re-designing the associated electrical equipment to best support the current facility needs and would not be limited to "in-kind" replacement. The new design should consider optimizing the size of all components based on peak demand load of the building. The new generator system is recommended to have the capability of paralleling multiple generators to support the entire building with automatic features for transfer and load shedding. Closed transition automatic transfer switches should be considered to allow for regular scheduled testing and jogging of the generators while being connected to building load and to not interrupt power. New digital metering ("smart metering") should be included in new equipment capable of power and energy measurements, power quality analysis, and data/event logging. Existing protective relaying shall be replaced with new and the design should address needs for the medium voltage equipment as well as the switchboards and generator equipment. In order to accurately design for the new equipment, a short circuit/coordination/arc flash study and a power factor correction study for these two buildings are also recommended as part of the new equipment installation. Also, electrical clearance issue assessments, alternative location assessments for the new equipment and their supporting systems, and remote generator status panels/computer interface requirement assessments are recommended during the design phase.

The estimated price for this project is between $1,000,000 and $5,000,000.
