American Textile Company

Duquesne, PA – 2015-2018 – $ 3,206,000.00

Scope of Work:
Neumeyer Environmental provided excavation, backfill, and structural services to American Textile Company in Duquesne, PA. The industrial park was built on top of a slag that has expanded over time as water has seeped into it, causing the building supporting columns and floor in the factory to raise and become uneven. NES mitigated this by excavating all slag from underneath two sections of the factory and backfilling with stone.

NES installed a large containment around the entire work areas inside the factory to protect the factory workers and the manufacturing processes. We then installed temporary structural supports, removed the floor slabs, and excavated all slag out from underneath each area, which was as deep as 30 feet in areas.

Upon completion of excavation, NES backfilled the excavations with stone, compacting it to meet building design standards and ensuring its stability for the future. We completed the work by re-installing permanent support beams and replacing the floor slabs. NES performed this work in two phases in different areas of the plant to accommodate the factory’s production.

Throughout the work, NES performed dust and noise monitoring inside of the work area as well as outside of the work area in the factory to ensure both NES and American Textile workers were not exposed to hazardous levels of either.

Babcock Boulevard Winding Facility

Stemple & Ward
Pittsburgh, PA – 1996 – $120,000

Scope of Work:
Stemple & Ward purchased a public transportation garage and converted it to an electric motor winding facility. Years afterwards, gasoline odors began seeping through the sewage vents. Investigation identified four historic 5,000 gallon underground storage tanks previously used for leaded gasoline. The tanks had leaked into the surrounding subsoils and migrated into the storm sewers.

Neumeyer Environmental used ground-penetrating radar to locate the tanks. We excavated the tanks and removed the mix of water and product. Neumeyer Environmental shipped 20,000 gallons off-site to a recycler for processing. Neumeyer Environmental purged the tanks of flammable gas, removed and disposed them at a licensed tank disposal facility. 2,500 tons of adjacent subsoils required removal and disposal at a regulated facility.

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.
