The Pittsburgh Parking Authority yesterday awarded $36.8 million in key contracts on the Grant Street Transportation Center, which will include a new Greyhound Lines station and a 1,050-space parking garage.

"What we did today means this is going to be built, one way or the other," said authority board Chairman Steve Irwin.

The biggest contract, $29.2 million, goes to Massaro Corp. of O'Hara, for building the concrete structure. Authority Executive Director David Onorato said the firm had already guaranteed it would do the job for that price, and beat out three other bidders who would have charged $31 million to $35 million.

The contracts push the total price of the complex, at Liberty Avenue and 11th Street, Downtown, to $42 million, he said -- up from $35 million when the plan was unveiled in 2003.

He said footing and foundations for the garage are already going in, even as demolition is wrapping up. Construction is to start in August. The garage is expected to open in late 2007, the station in 2008.

Three other contracts went to Lighthouse Electric, for $3.6 million, for electrical work; Climatech Inc., for $2.1 million, for mechanical work; and W.G. Tomko Inc., for $1.9 million, for plumbing and fire protection. All were the lowest bidders.
