GTS Duratech

Atlantic Research Corporation
Arlington, VA – 1992 – $50,000

Scope of Work:
Neumeyer Environmental was contracted to perform decontamination of a radiological contaminated facility with 54 actuator rod sleeves cast into the walls of a containment scheduled for removal.

Neumeyer Environmental was required to core-drill holes through high-strength concrete to remove the sleeves. Neumeyer Environmental developed a process to collect, filter, and recycle drilling lubricant to reduce the volume required to perform the work. Neumeyer Environmental was able to minimize the amount required to less than five gallons by employing this method. The lubrication equipment was solidified on site. The project involved multiple mixed waste streams, such as radiological contamination, asbestos, mercury, lead, and guano debris.

The project was completed on-time and within budget.

PennDOT Ewing Park Bridge

Mekis Construction Company
Ellwood City, PA – 2005 – $102,000

Scope of Work:
In preparation of demolition of a 1930’s bridge, PENNDOT encountered lead in the soil beneath the span. Lead had reached the soil from the paint as it weathered through the years and from past sandblasting operations to prepare the bridge for repainting. Removal of the contaminated soil was required for the project to continue.

High concentrations of lead were determined through analystical testing in the top 12 inches of soil. The soil was a mix of loose granulated slag and sandy loam. The hillside beneath the bridge was steep with a 1-to-1 slope (45 degrees) and about 150 feet long.

The long, steep slope made use of conventional excavating equipment impractical and dangerous. Instead, Neumeyer Environmental utilized a HEPA filtered high-volume vacuum pump. Workmen traversed the slope, tethered to supporting ropes with full body harnesses, and pumped the contaminated soil using five-inch diameter vacuum hoses. The vacuum transferred the soil up the slope to a bagging station. Tthe contaminated soil was disposed at regulated facility.

Neumeyer Environmental removed 817 tons of contaminated soil from the slope in two weeks.

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.

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.

North Shore Connector

North Shore Constructors I and II
Pittsburgh, – 2005-2009 – $487,000

Scope of Work:
Neumeyer Environmental was contracted to provide environmental management and construction support services for a subway connector tunnel beneath the Allegheny River from downtown Pittsburgh to the North Shore area. Neumeyer Environmental provided remediation services for abandoned asbestos-insulated steam pipes, lead compliance and abatement activities, impacted subsoils from previous historical activities, water quality discharge management and sampling and analysis in accordance with the Pennsylvania Management of Fill policy.

This project is a multi-year, multi-contract effort that is anticipated to span over five years.
