Geotechnical Peer Review

We provide collaborative peer review for projects involving geotechnical design and construction and also part of a due diligence process for real estate investors.  Example projects:

• Winthrop Square, Boston, MA – a sixty story building in downtown Boston’s financial district with four levels of underground parking using the up down construction method
• Martin’s Point Bridge, Portland, ME – 1,300 foot long design build project carrying US Rte 1 between Portland and Falmouth Foreside
• State Pier Wind Energy Project, New London, CT – $250 million development of waterfront piers into a state-of-the-art heavy-lift capable port facility to support three offshore wind projects totaling more than 1,700 MW

Due Diligence

We provide pre-purchase/investment review of geotechnical aspects of real estate development projects.  Example projects:

• Multiple warehouse facilities ranging from 320,000 to 930,000 square feet, Linden, NJ
• Multi-story Residential Building, Revere, MA – five story building designed for support on foundation soils improved with rammed aggregate piers
• Basement Drainage Design, Washington, DC – two story underground parking 18 feet below the water table and 25 feet below flood level
• Mid-rise Building, North Bergen, NJ – analysis of existing building settlement, projection of future settlement and remedial options

Forensics and Expert Witness

We provide forensic analysis, expert witness in mediation/arbitration/litigation disputes.  Example projects:

• Millennium Tower, San Francisco – evaluation and mediation testimony of 58 story building settlement, foundation performance and remedial options
• Building Settlement, Hospital Building, Manhattan, NY – evaluation and mediation testimony for claim relating to excavation for a new building with a two level basement with sheet pile excavation support system and settlement of adjacent building
• Central Artery Project, Boston, MA – review and analysis of movement of 60 foot deep cut and cover tied-back soil mix wall excavation where third harbor tunnel enters Logan International Airport; taxiway settlement
• Cofferdam, Mississippi River, Memphis, TN – review and analysis of contractor claim involving defective cofferdam construction, seismic retrofit of Route 40 Bridge piers
• South Carolina Aquarium, Charleston, SC – review and analysis of foundation damage associated with ground movement of submerged slope along the Cooper River
• Excavation Support System Failure, New Orleans, LA
• Excavation Support System Failure, Miami, FL
• Slope Instability, Municipal Marine Facility, Glastonbury, CT – review and analysis of slope movement along the Connecticut River during construction of building and site improvements
• Foundation Settlement, Newark, NJ – review and analysis of settlement and underpinning repair of drilled shaft foundation for multi-story building and parking garage
• Wastewater Treatment Plant, Baltimore, MD – claim relative to installation of several thousand pilings
• Earthwork Claim, Industrial Project, Milford, CT – consultation to owner related to contractor claim for additional earthwork costs

Emergency Response

We provide emergency response for clients, most frequently following a storm event.  Examples include:

• Tropical Storm Irene, Vermont Agency of Transportation (VTrans) – triaged sites, developed on the spot designs to repair highway and railroad bridges, roadway embankments and slopes that were taken out of service following historic flooding
• MetroNorth Commuter Railroad – developed slope stabilization scheme following Tropical Storm Irene induced landslide causing earth and mud to bury the tracks of the Hudson Line, shutting down service just north of Manhattan in the Riverdale section of the Bronx
• GEODesign provided emergency engineering services to repair damage caused by Hurricane Ida at the TPC River Highlands Golf Course in Cromwell, CT.  Stormwater washed away a portion of the riverbank into Connecticut River, leaving a “washout” measuring approximately 60 feet deep, 90 feet across the riverbank, and 75 feet into the slope.  A railroad track and an underground jet fuel line, directly adjacent to the golf course, were undermined and left hanging in the air.  Both the railroad and the fuel line had to suspend their services.  GEODesign performed soil borings and stability analyses, and helped to engineer a solution involving geo-synthetic reinforcement and riprap protection.
