Atwater Office Complex in Devault, PA
The 388-acre tract is the site of a former processing facility for agricultural lime. The property contains an 80+ acre, 200 feet deep quarry (the source of raw material for the plant), the former processing plant area, and a 24+acre landfill for the residual lime waste. Advanced GeoServices performed extensive historical reviews, site reconnaissance, sinkhole assessments, and field investigations using test borings, test pits, rock coring, and geophysics. Our geotechnical investigations and designs were critical in the site layout strategies to help avoid sinkhole risks, develop cost-effective foundation designs, help with cut/fill balancing and to minimize rock excavations. Advanced GeoServices also prepared the mine closure permit application which required re-grading of 200-feet high vertical quarry walls to provide safe slopes and significant erosion and sediment controls.
Internet Fulfillment Center in Gap, PA
Advanced GeoServices has been involved with this project since the early planning stages. Our client, a major clothing retailer, wanted to build an Internet fulfillment center in Lancaster County Pennsylvania. We assisted them with a boundary and topographic survey, a Phase I Environmental Site Assessment, a seismic refraction survey, a geotechnical/infiltration investigation, a pre-engineered plan, land development application and coordination, coordination of a NPDES permit and a sewer module, a grading permit application, roadway pavement evaluation, an off-site water line, record plans, client and construction documents, building permit coordination, and construction phase services.
Justison Landing Residences in Wilmington, DE
The Justison Landing redevelopment is located on a 25-acre waterfront tract in Wilmington, Delaware. The site had been occupied for more than 100 years by industrial facilities including a former shipyard, large tank storage, and other factory/warehouse buildings. The project includes six separate parcels, including several multi-story residential buildings with ground floor retail space and parking decks, multi-story office buildings and a high-rise hotel and parking structure. Advanced GeoServices’ practical approach to the investigation greatly reduced the number of borings required to address the various geotechnical issues. Our foundation designs and floor slab support procedures minimized excavations and reduced the generation of spoils, which in turn minimized the environmental costs associated with disposing of these materials. Our selection of foundation type for each structure included consideration of the expected below-ground obstructions in order to reduce construction delays and extra costs, and our analyses led to the re-use of large foundation remnants, saving their demolition costs.
Lenfest Plaza in Philadelphia, PA
The Pennsylvania Academy of Fine Arts developed Lenfest Plaza on the site of the former Cherry Street. The Plaza is meant to serve as a gateway between the adjacent Philadelphia Convention Center and the remainder of the center city area to the west. The focal point of the Plaza is the Paint Torch, a 51 feet tall illuminated paint brush and its accompanying dollop of paint created by Claes Oldenburg. The paint brush is situated on the west side of Broad Street and leans over the sidewalk at a 60 degree angle. The foundation and base of the sculpture had to be entirely below ground, in order to provide the illusion that the brush had been jabbed into the ground. The foundation design requirements were unique; it had to handle the eccentricity caused by the angle of the brush as well as lateral wind loadings. Although the sculpture weighed only 12,000 pounds, the resulting foundation loads were as much as 180,000 pounds in compression and 120,000 pounds in tension. Furthermore, the numerous utilities beneath the former Cherry Street included telephone, a water main and other water supply lines, the storm/sanitary sewer and an abandoned brick sewer, all within a 20-feet wide cartway; these obstructions limited the types of foundations that could be installed for this project.
Bridge Repair in Kennett Square, PA
During the severe flooding experienced on September 15, 2003, four bridges in Kennett Township were damaged. This damage included severe erosion of approach embankments and upheaval of bridge deck and approach pavements. Advanced GeoServices was requested by Kennett Township to provide geotechnical consultation with respect to the repair of these bridge elements and construction oversight during the performance of these repairs.
Financial Technical Operations Center in Devon, PA
The development/renovation of an existing office complex contained 244,000 square feet of building footprint which was achieved by razing a 125,000 square foot structure, constructing a new structure, and retrofitting and integrating an adjacent existing building. The project also required the construction of a new infrastructure system, including utilities, two stormwater management basins, and new driveways and parking areas. The site is located in the Chester Valley Area, which is underlain by shallow limestone, and is noted for sinkhole experiences that threaten site improvements. By using several investigation techniques, Advanced GeoServices was able to cost-effectively characterize the site geotechnical and geologic conditions. Advanced GeoServices helped develop techniques and sequencing strategies to maximize the use of the on-site soils and minimize the potential for sinkhole development. Our expertise in karst terrain and knowledge of site conditions, project parameters and the owner's concerns were essential for the quick and efficient remediation of those sinkholes which did occur.
Pipeline Crossing in East Whiteland Township, PA
The development of the Atwater Office Park included the construction of an entrance road, requiring more than 6 feet of additional fill. The road alignment passes over three gas pipelines, and the additional fill would create stresses that exceeded the allowable levels for the existing pipes. Advanced GeoServices evaluated the geotechnical conditions and developed a construction scheme that included the use of geofoam, a light weight fill. The installation scheme included excavation of the existing soil cover to within one foot of the pipelines and the use of the geofoam blocks to backfill the excavation and extend the fill to the final road subgrade elevation. This configuration allowed for quick entry into the excavation in the event of emergency pipeline repairs; in the event of an emergency the geofoam blocks could be quickly removed and repair personnel could immediately enter the excavation to perform the final excavation and repair activities.
