4.0 Utilities - General:

4.1 Electric

The building is presently fed with a temporary service consisting of 800 Amps, 120 / 208 VAC electric power off of a Con Edison meter located in a protective enclosure and shed situated at the northwest corner of the site. The power presently feeds a switch providing emergency power for emergency lighting, a single service elevator, and temporary light stringers. This current electrical service is insufficient for the needs of the remediation / deconstruction Contractor; therefore, additional power must be provided.

The mechanical engineering consultant assessed the projected electrical loads, and prepared drawings showing the scope of the required electrical work. Con Edison reviewed the load request and the drawings, and determined that its equipment located in a vault on Barclay Street can adequately meet this requirement. The Construction Manager will contract with a licensed electrical contractor for the reactivation of a portion of the original building system.

Con Edison recently inspected the transformer installation located in vaults on Barclay Street that originally fed the building, and determined that one of the three transformers in the vault is currently active and the remaining two can be reactivated. Prior to increasing the power to the building, Con Edison requires that the existing inactive electrical equipment be cleaned of dust and rust, and then tested by the licensed electrical contractor. This work is to be conducted under a re-opening of NYS DOL Variance 05-0919. Con Edison will then inspect the electrical equipment. Once accepted, Con Edison will direct the electrical contractor to disconnect the temporary service. Con Edison will then reactivate the additional transformers.

The licensed electrical contractor will activate power in the main building riser to the main distribution panel on each floor. All distribution throughout the floor will be inactive. Power to the passenger and freight elevator will be restored. The elevator equipment will be gross cleaned and restored to operation by a licensed elevator maintenance contractor.
