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.

US Air Force Reserve 911 Base – Pittsburgh Airport

Joseph B. Fay, Inc.
Pittsburgh, PA – 1997 – $275,000

Scope of Work:
Neumeyer Environmental provided environmental management services for an obsolete jet fuel storage facility to be dismantled and removed prior to construction of a new facility. The site included two 280,000 gallon aboveground tanks, two 25,000 gallon underground tanks, one 5,000 gallon underground tank and one 250 gallon underground tank. During the forty-plus years the facility operated, numerous leaks and spills contaminated the surrounding soil with petroleum hydrocarbons.

Prior to demolition, Neumeyer Environmental evacuated, purged, and decontaminated the pipe systems and tanks. Neumeyer Environmental also dismantled six support buildings. Since the facility was active, Neumeyer Environmental was limited to cold-cut techniques including pneumatic saws and a hydraulic shear mounted to a tracked excavator. After removing the tanks and structures, Neumeyer Environmental excavated the impacted subsoils.

The Air Force’s original design called for soil to be hauled off site for disposal. Neumeyer Environmental used land farming techniques to clean 50,000 tons of contaminated soil as a value-engineered approach that substantially reduced the cost and duration of the project and was environmentally superior to off-site disposal.

PennDOT SR 22 Road Widening Section B09

Golden Triangle Construction
Pittsburgh, PA – 2008-2009 – $394,000

Scope of Work:
Neumeyer Environmental was contracted to manage contaminated soils that had been identified in a former auto salvage yard within the roadway widening and expansion project. The adjacent streambed had been contaminated as well and required remediation to remove contaminated sediments, enclose the stream in a box culvert and perform minor relocation in accordance with PADEP requirements. Neumeyer Environmental also provided sampling and analysis in support of the work.

Neumeyer Environmental was also contracted to remove asbestos building materials from structures scheduled to be demolished.

Beaver Valley Nuclear Power Station Demolition

First Energy Corporation
Shippingport, PA – 2005-2006 – $350,000

Scope of Work:
Homeland security regulations required removal of five multi-story office buildings surrounding this nuclear power station in order to open up defensive lines of sight. The buildings were contaminated with asbestos-containing materials and electrical equipment that contained PCBs.

Neumeyer Environmental removed over 2,500 cubic yards of asbestos materials and approximately 250 cubic yards of PCB-containing electrical components. Following removal of these contaminants, Neumeyer Environmental demolished the structures and recycled 1,900 tons of steel and non-ferrous metals. One structure housed a full-scale model breeder reactor, 14′ in diameter and 50′ high, constructed during the 1950s. We constructed a shipping container and relocated the model to a storage facility. The reactor model will be displayed in a museum dedicated to the history of nuclear power.

The renovation and upgrade of the nuclear power facility is an ongoing process due to the magnitude of the work. The project is being performed with a focus on recycling and salvage in support of environmental conservation.
