Environmental Compliance Facility and Parking Garage

Location Pittsburgh, PA

Client Allegheny County Sanitary Authority (ALCOSAN)

Services Program Management

Project Value $50 Million

As part of its Clean Water Plan, ALCOSAN is undertaking a program to expand its plant on the Ohio River in Pittsburgh, PA. The plant expansion projects will increase ALCOSAN’s capacity and help reduce the number of overflows caused by excess stormwater. Hill is teamed with G. Stephens Inc. and provides project management services for multiple projects to facilitate the advancement of the plant expansion program. Specific projects include:

Parking Garage: ALCOSAN undertook a project to construct a 400-space, multi-level parking garage near the plant entrance. Nestled between the Ohio River to the west and a railroad alignment to the east, the project team had to maximize parking availability while reducing the plant’s overall parking footprint. As part of the management team, Hill helped with constructability reviews and value engineering.

Environmental Compliance Facility (ECF): The new three-story ECF will include laboratory space for ALCOSAN’s Industrial Waste Program and Residual Waste Program on the first floor and office space on the second and third floors. The ECF will also feature a patio/rooftop garden on the second floor. Construction is expected to conclude in 2024.

By enabling demolition of ALCOSAN’s existing laboratory facility, the ECF paves the way for one of the final plant expansion projects: the construction of two new primary sedimentation tanks. The existing laboratory is one of the buildings that will need to be demolished to accommodate these two tanks.

As part of the management team, Hill is providing project management services and coordinating all mechanical, electrical, and plumbing work, helping promote efficient construction in line with ALCOSAN expectations.
