Construction work will begin this September
The presentation was largely conducted by Eric Bilsky, assistant director of capital programs for the Port Authority Transit (PAT). He is the engineering manager for the project.
The City of Pittsburgh, in a cooperative agreement with PAT, intends to pay for the resurfacing of the parking lane in that same stretch. The city owns the curbs and parking lane.
The city is also replacing the curb on both sides of the street, and replacing the handicap-accessible sidewalk ramps as part of the project. Curbs will be replaced and depressed curbs at driveways on Warrington Ave. will be rebuilt. Sidewalks are not currently in the scope to replace.
PAT will do the entire project, with the city reimbursing the agency for their share of the project.
PAT's responsibility is where the tracks currently are, which are also the travel lanes for the public.
Bids will be opened in another week, and then presented to the PAT board at its July meeting. If approval is granted, work would begin Sept. 1.
The plan is to work, depending on the weather, until Thanksgiving, and then begin again in spring around late March. The entire project is estimated for completion in mid-summer, 2013.
The project will start at Haberman Ave. with the right lane toward Arlington Ave. One direction on Warrington Ave. will be open for traffic at all times. Haberman Ave. will always be open except when the intersection is being reconstructed. Arlington Ave. will always be open.
There will be ample signage with detours, but no on-street parking during the project.
A week or two in advance, flyers will be delivered door-to-door to inform residents of work in their portion of the street.
"We can do this without totally ruining your lives for a long period of time," Mr. Bilsky said of the project.
Questioned whether the city could provide labor at cost to replace the sidewalks, Mr. Bilsky said the matter needs to be presented to the city. To a question about crosswalks, he said there will be painted lines.
The plan is to go down 5.5 inches and rebuild back up with new pavement designs. It is being done that way for cost and time.
Mr. Bilsky said at a depth of 5.5 inches there will be an intermediate layer of asphalt followed by 4 inches of fiber reinforced concrete.
To an attendee's question about the longevity of using this construction method, Mr. Bilsky said it can provide the longevity as much as comparable pavement designs which have been used by PennDOT.
Questioned about the trolley vibration, Mr. Bilsky said for light rail vehicle traffic, it will be the same vibration felt today. He said it is a substructure borne vibration.
There will be a rubber coating applied to the rails to isolate them from the concrete and prevent cracks caused by vibrations.
To a question of who will watch the contractor, it will be PAT staff and consultants who will watch, inspect, and test the concrete.
"We'll always be watching what they're doing," Mr. Bilsky said of the contractor.
"It all boils down to the integrity of the inspection," the attendee said.
In announcements after the presentation, Liz Style of the Mayor's Office said National Night Out will be observed on Aug. 7.
Next, Councilman Bruce Kraus introduced his new constituent services coordinator, Barbie Arroyo.
A New York City native, she speaks four languages, and previously worked for the federal government. After only five days on the job she fielded 93 calls, he said.
Another new face at neighborhood meetings will be Aerion Abney, legislative assistant to state Rep. Jake Wheatley, Jr.
He moved here in 2006 from Philadelphia, and has a masters degree in social work from the University of Pittsburgh.
