The Allegheny County Sanitary Authority (ALCOSAN) is undertaking the transfer of various pump station and equalization facilities under its Regionalization effort. These pump stations and equalization tanks have undergone a facility assessment to identify operational status, condition, safety concerns and capital improvement needs. Three pumping facilities have been identified for rehabilitation and include Brush Run Pump Station in Upper Saint Clair, Herbst Hollow Pump Station, in Kennedy Township, and Oakdale Pump Station in Oakdale, PA. As a subconsultant to Gannett Fleming, Sci-Tek is providing the following services:

  • Perform preliminary subsurface explorations to support the designs and construction documents for the proposed Oakdale Pump Station modifications.
  • Provide preliminary and final subsurface exploration reports that contain our conclusions and recommendations based on the data obtained, as well as geotechnical construction specifications.
  • Provide limited bidding phase support with respect to geotechnical engineering.
  • Provide limited construction phase support with respect to geotechnical engineering.

ENVIRONMENTAL

  • Collect bulk asbestos samples according to current EPA sampling requirements and submit samples to a National Voluntary Laboratory Accreditation Program laboratory for analysis.
  • Inventory hazardous materials for the buildings to identify Universal Wastes, including fluorescent bulbs, lighting ballasts, thermostats, exit signs, batteries, pesticides, and other hazardous materials.
