Indefinite Delivery Contract for A-E Services for Geotechnical and Geo-Environmental Services for USACE, Philadelphia District
Advanced GeoServices conducted a geotechnical investigation to evaluate the subaqueous materials present within the anchorage as part of the navigational deepening activities for the Delaware River, Marcus Hook Anchorage. This investigation was conducted using vibrational core technology to continuously sample marine sediments to obtain representative samples for identification and geotechnical testing. The samples were logged, visually identified, and subjected to gradation analysis to determine and document the grain size characteristics of the materials present. The USACE, Philadelphia District rated Advanced GeoServices’ performance on the contract as “Very Good” saying that Advanced GeoServices provided highly experienced personnel for the project and worked well with its subcontractors, completing all tasks on time and on budget.
Chester County Trail in Chester County, PA
Portions of the Chester Valley Trail are located on the former rail bed of the Chester Valley Railroad which was constructed in the mid-1800’s. Testing of the near surface materials identified fill with concentrations of arsenic above the Pennsylvania Act 2 standards. The Chester County Department of Facilities and Parks retained Advanced GeoServices to conduct closure activities under Act 2 and demonstrate that the trail as designed served to eliminate pathways of exposure to the fill. Advanced GeoServices also performed testing of the surface waters that cross the trail alignment to demonstrate the fill was not impacting surface water quality.
Interceptor Sewer Relocation in Havertown, PA
Due to the proposed construction of the I-476 highway, a study was conducted to determine the best relocation of the 24” and 30” interceptor sewers to serve the operation and maintenance needs of the Authority. The project was completed and put into operation in 1989.
Bridge Abutment Stabilization
A township needed to stabilize an existing 100+-year old railroad bridge over a creek. The bridge abutments are masonry (mortared stone on the exterior with a rubble interior) and were deteriorating due to flood damage, scour, and freeze/thaw action. Advanced GeoServices developed a rehabilitation program consisting of grout-filled bags and spray-applied concrete to fill the scour areas as well as to encapsulate the abutments. After the abutments were encapsulated, the rubble interior was pressure grouted to fill the voids and create a solid mass.
Municipal Wastewater Treatment Plant Upgrade Evaluation in South Coatesville, PA
A land developer was seeking to add 166 housing units to the Borough of South Coatesville and the Borough required the developer to upgrade the existing wastewater treatment plant. The requirement for the upgrade included accommodation of the additional hydraulic and organic load incurred due to the additional housing units. The wastewater treatment plant consisted of an influent mechanical screen, a pump station, 2 Sequencing Batch Reactors (SBRs) in parallel, and a chlorine contact tank.
Mill Lane Sanitary Lift Station Design in East Whiteland Township, PA
A large portion of the East Whiteland Township’s sanitary flow is collected and pumped by the Mill Lane Lift Station. The former station contained two 1,400 GPM pumps, but is without redundancy if a pump is offline for maintenance and is over 30 years old. Advanced GeoServices was retained by East Whiteland Township to provide design engineering and construction services to replace the lift station with a new station capable of handling current and future projected sanitary flows.
