Gay Street Bridge Replacement

Nyleve Bridge Corporation
Phoenixville, PA – 2008-2009 – $900,000

Scope of Work:
A primary bridge over French Creek in Phoenixville, Pennsylvania was being replaced by PennDOT. Several environmental issues required address as part of the work including lead paint and asbestos-containing materials on the existing bridge and elevated contaminants in the subsurface soils. The piers and subsurface preparations were within a former steel-making facility with elevated inorganic constituents of concern. Neumeyer Environmental was contracted to address and manage these environmental aspects of the work.

Management of on-site soils required sampling and analysis, use of personal protective equipment, segregation of contaminated materials and water quality issues associated with installation of the pier adjacent to French Creek.

Neumeyer Environmental performed select earthwork, demolition, on-site placement and off-site disposal of surplus materials and debris. We also managed the discharge waters from the coffer dam by installing a high volume pump and treat system that allowed direct discharge to French Creek. The project required approximately 10 months to complete from plan preparation and sampling through excavation of the pier subgrade.

Pennsylvania Turnpike Commission Toll Plaza

Mosites Construction Company
Warrendale, PA – 2002 – $155,000

Scope of Work:
The Pennsylvania Turnpike Commission constructed a new interchange at Warrendale (Milepost #31). An abandoned gasoline station built in the 1950s had occupied part of the construction site. The gas station’s ten gasoline and diesel tanks, ranging from 3,000 to 10,000 gallons capacity, had leaked fuel into the soil. Cleanup was required prior to the beginning of new construction.

Neumeyer Environmental excavated 3,000 tons of contaminated soil and transported it to a thermal processing facility where it was cleaned for recycling for use as roadway subbase on the project. Neumeyer Environmental removed and disposed of 100 tons of hazardous soil, 1,000 gallons of contaminated liquids, and the remnants of the underground fuel system. We also decontaminated and disposed of the old fuel tanks.

Our ability to recycle the contaminated soil substantially reduced our client’s disposal costs. The construction project proceeded on clean land. This project was completed on-schedule and on-budget.

Duquesne Flyover Project

Mosites Construction Company
Duquesne, PA – 2008-2009 – $1,200,000

Scope of Work:
The Regional Industrial Development Corporation (RIDC) constructed a roadway to convey traffic over an existing rail line to Duquesne Riverplace at the old Duquesne Works Steel Mill property. The property was approved as an ACT 2 site and is currently under phased redevelopment.

Management of on-site soils required extensive sampling and analysis, use of personal protective equipment, segregation of contaminated materials and removal and management of subsurface debris due to the historical steel-making activities.

Neumeyer Environmental evaluated and managed approximately 40,000 cubic yards of impacted soils in preparation of the more than 3,000 linear feet of road construction. We worked in close coordination with the prime contractor to develop approaches that facilitated project completion and minimized costs.

Neumeyer Environmental performed the earthwork, demolition and on-site placement of surplus materials and debris such that the majority of the materials were able to be beneficially re-used on-site. Remnants of asbestos containing materials were encountered during the excavation that required abatement during portions of the work. Neumeyer Environmental was able to minimize the schedule impacts that may have resulted from this previously-unknown development. The project required approximately 14 months to complete from sampling through final excavation

Corless Flyover Project

Mosites Construction Company
Pittsburgh, PA – 1997 – $350,000

Scope of Work:
The Allegheny County Port Authority Transit developed a busway and bridge to access the newly constructed Pittsburgh International Airport. An abandoned dump site was located within the alignment. Soil analysis indicated lead contaminated soils within the excavation limits.

Neumeyer Environmental removed, managed and disposed 18,000 tons of contaminated soil to an off-site regulated facility.

After completion of excavation to the foundation grade, Neumeyer Environmental overlaid the subgrade with barrier material to allow construction of the roadway to proceed with the contractor’s specialized crews. The potential for worker exposure to contaminants of concern was eliminated by this approach. The project was completed on-time and within budget.

PennDOT 38th Street Realignment Project

Mekis Construction Company
Erie, PA – 2003-2004 – $380,000

Scope of Work:
Realignment of 38th Street included multiple environmental challenges.

  1. Decontamination and removal of several structures that contained asbestos-containing building materials.
  2. Removal of a gasoline station, including demolition of a building and decontamination and removal of four 10,000-gallon underground gasoline tanks.
  3. Relocating the Mill Creek stream bed to an area that had been used as a landfill and that contained organic and chemical waste.

Neumeyer Environmental removed and disposed the asbestos-containing materials, demolished the structures and disposed the resulting uncontaminated construction debris. Neumeyer Environmental demolished the structure and disposed the construction debris. We decontaminated and removed the four 10,000-gallon underground tanks. Inspection of the surrounding soil revealed that no contamination had occurred. Neumeyer Environmental removed 20,000 cubic yards of soil contaminated with organic and chemical waste. The soils were profiled as residual rather than hazardous waste, substantially reduced the cost of its disposal.

The Mill Creek stream bed was successfully relocated as required for realignment of 38th Street.
