The Pittsburgh-Allegheny County Sports & Exhibition Authority is undertaking major repairs to the chiller plant at the David L. Lawrence Convention Center after one of the chillers failed and two others are headed in the same direction.

Authority board members today authorized a $207,798 contract with Trane U.S. Inc. to recondition two of the chillers. They also ratified a $10,633 payment already made to Trane after it dismantled a third chiller and investigated the cause of its failure.

SEA officials said the chillers, which supply air conditioning, are having problems because they are not operating near capacity, in part because a proposed hotel that was to be attached to the convention center was never built.

The chillers are designed to run continuously but because of lower-than-anticipated capacity are kicking on and off too much. That is causing excessive wear and tear, the authority said.

In addition to hiring Trane to recondition two of the failing chillers, the board approved a contract not to exceed $38,500 with H.F. Lenz Co. to determine if modifications need to be made to the plant.

Also today, the board authorized a reimbursement not to exceed $36,500 to the Pittsburgh Pirates for design work related to the repair of expansion joints at PNC Park. The failing joints have caused water leaks, although no structural damage, according to the authority.
