G40 SITE ELECTRICAL UTILITIES

SYSTEM DESCRIPTION

Demolish the existing underground primary service, pad-mounted transformer and secondary service and provide a new underground primary service, pad-mounted transformer and secondary building service.

The site electrical utility system consists of all power from the existing distribution system point of connection including all connections, accessories and devices as necessary and required for a complete and usable system. This section covers installations up to within 5 feet (1.5 meters) of new (or existing) building location.

The existing underground primary system in the area of the facility is scheduled for upgrade/replacement. Multiple tie-ins may be required to accommodate existing and new circuit placement. Point of connection of the electrical is proposed in the area of the existing manhole.

The point of connection to for the underground communication system to the building is from manhole C-113 and will remain.

GENERAL SYSTEM REQUIREMENTS

Provide an Electrical System complete in place, tested and approved, as specified throughout this RFP, as needed for a complete, usable and proper installation. Install all equipment in accordance with PTS Section G40 and the manufacturer's recommendations. Where the word "should" is used in the manufacturer's recommendations, substitute the word "must".

Provide site electrical utilities systems and components that support project sustainability goals of Part 2 Section 01 33 29.05 20, Sustainability Reporting for Design Build.

G4010 ELECTRICAL DISTRIBUTION

Connect to the existing 12.47kV, three phase, four wire, 60 Hertz electrical power system. The connection point must be underground at Manhole 113 and extended to the project site underground in ductbank to a Pad Mounted Transformer. If project phasing requires the existing Pad Mounted Transformer to remain in service after the new Pad Mounted Transformer has been installed, a temporary tap shall be provided in Manhole 113 to feed both Pad Mounted Transformers. Once the existing Pad Mounted Transformer has been removed, the temporary tap in in Manhole 113 shall be removed.

The available fault current at the point of connection must be assumed to be an infinite bus.

G401001 SUBSTATIONS

Not used

G401002 TRANSFORMERS

Provide a three phase pad mounted transformer to feed the facility.
