SECTION 0030

DESCRIPTION OF WORK

REPLACEMENT OF FRAZIER STREET STAIRS

4TH WARD – CITY OF PITTSBURGH

ALLEGHENY COUNTY, PENNSYLVANIA

This work is to remove the existing deteriorating concrete stairs that connect Bates Street, Frazier Street, and Romeo Street, and to construct new concrete stairs (along a new alignment).

The new stairs consist of a combination of cast-in-place jumper walk stairs and elevated precast stairs. The project is located near the intersection of Bates Street and the I-376 interchange in the South Oakland neighborhood in the 4th Ward of the City of Pittsburgh.

The existing concrete stairs ascend approximately 75 feet in elevation from Bates Street (approximately 250 feet north of its intersection with the I-376 westbound off-ramp) to the west end of Frazier Street. At about the midpoint of the stairs, a second set of stairs ascend approximately 50 feet in elevation to the south end of Romeo Street. The existing elevated concrete stair stringers and platforms rest on concrete piers that are believed to be supported by shallow spread footings, although no design drawings or construction drawings of the existing stairs are available.

The proposed stairs will be accessed off Bates Street approximately 200 feet south of the existing stairway access point and will ascend to Frazier Street through vacant City properties. Based on historical maps and photographs, the vacant properties were once occupied by residential structures. The proposed concrete stairs will be constructed using a combination of on-grade cast-in-place jumper walk stairs and elevated precast stairs. The import and placement of engineered fill (AASHTO No. 1’s) will be required to accommodate the proposed grade of the jumper walk stairs. The precast elevated stairs will be supported by cast-in-place columns and shallow spread footings. Due to the presence of highly weathered claystone and “red beds” on the slope below Frazier Street, the subgrade beneath the spread footings will likely require several feet (or more) of undercut and AASHTO No. 1 backfill.

The work will generally consist of the following tasks:

• Design and implementation of a traffic control plan.

• Construction surveying.

• Installation of compost filter sock and rock construction entrance.

• Clearing and grubbing within the immediate work area.

• Demolition/disposal of existing concrete stairs.

• Class 3 excavation for jumper walk stairs and elevated stair footings.

• Construction of cast-in-place foundations, columns, and landings.

• Installation of precast stair sections.

• Preparation of subgrade and placement of engineered fill (AASHTO. No. 1).

• Construction of on-grade cast-in-place jumper walk steps and sidewalk.

• Fabrication and installation of hand railings and bike runnels.

• Removal of E&S Controls and site restoration.
