Atwater Village, Chester County, PA

  • Geotechnical and environmental consulting and COT services for the 147-acre mixed-use development with 549 single, twin, and townhomes, nine apartment buildings, a daycare facility, and four commercial pad sites.
  • Saved the client an estimated cost of over $2,000,000.

Horseshoe Casino, Baltimore City, MD

  • Geophysical testing, geotechnical and environmental consulting for new two-story 140,000-SF casino and associated seven-level, 3,500-car, above grade parking garage.
  • Relatively deep layer of fills and soft clayey soils required use of deep foundations. Subsurface explorations were in excess of 90 feet, where rock cores were obtained.
  • Observed & evaluated several static & dynamic load tests on CFAs to develop installation criteria and allowable loads for CFAs of different diameters.

Waugh Chapel South Building 11, Crofton, MD

  • Three-story steel framed building is situated over controlled fills and native soils at a former sand and gravel mine.
  • GTA performed design-phase exploration for the building. GTA’s exploration included two in-situ dilatometer soundings. The results of the DMT soundings allowed us to significantly increase the allowable bearing pressure that was previously assigned, based on Standard Penetration Test (SPT) data, resulting in reduced footing sizes, and construction cost savings.

University Terrace, Washington, D.C.

  • GTA provided value-engineering recommendations for a single-family house to be constructed at the location of a former tennis court and several retaining walls which were to be reused to support the basement walls.
  • GTA’s exploration program included excavator-pushed DMT soundings, performed adjacent to the existing retaining wall concrete footings.
  • Spread footings were recommended, thus eliminating the need for a specialty foundation system, and saving a significant cost for the project.

Three City Center, Allentown, Lehigh County, PA

  • Provided geotechnical services to facilitate the design and construction of the 166,000-SF, seven-story office/retail building in downtown Allentown.
  • GTA was able to provide significant cost-savings through the use of a limited foundation over-excavation/replacement scheme combined with deeper soil improvement/void stabilization through the use of compaction grouting techniques.
