Scope of Work

Building 2 and Hangar 7 Electrical Upgrades

Project Number VBDZ202102

BASE BID – BUILDING 2 SWITCH GEAR

DESCRIPTION:

The Contractor shall provide all construction services and materials to replace the existing 120/208 volt 3 phase; 4 wire 800 amp electrical switch gear equipped with an 800 main breaker, located in Building 2.

Switch gear that is currently in place is manufactured by Federal Pacific. The switch gear powers the main hangar (Hangar 1), along with all of Building 2 and Building 12.

New switch gear must be equivalent or superior in performance and capacity to the current configuration, and must be approved by the Contracting Officer Representative (COR) prior to purchase and installation.

A. Demo:

1. Remove existing switch gear

a. All material and debris will be discarded appropriately by the contractor.

b. Receipts and weigh slips of all recycled materials are to be submitted to the Civil

Engineer Squadron (CES) for inclusion in the project completion report

2. See attached base map to show location

3. See photos below for base map, electrical room entrance, and equipment details

B. Construction

1. New switch gear shall be configured as follows:

a. 2- 400 amp fused buckets

b. 1- 600 amp fused buckets

c. 1- 200 amp fused buckets

d. 2- 30 amp fused buckets

e. 6- 100 amp fused buckets

2. New switch gear is to have surrounding items reattached, once it is installed. Items include an existing side breaker panel, an existing E-MON D’MON sub meter mounted on it, and an existing trough. All items should function properly once reconnected.

3. New switch gear shop drawings and layout are to be submitted for approval by COR, prior to execution

C. QA/ QC

1. Reconnect to all loads with phase rotation remaining as existing setup. Confirmation testing with base electrician personnel present is required.

D. SPECIAL NOTE

1. Scheduling of the project is to be coordinated with CES. This switchgear is the main electrical supply feed for multiple maintenance work and office areas, as well as the main aircraft hangar.

Work is to begin on an Alternate Workday Schedule (AWS) Friday, and to be completed by the

Sunday evening of the same weekend, which is a total of 3 calendar days.

2. Empty conduits that are attached to the topside of the switch gear will not require reinstallation.

These conduits will be identified during the site walk through.
