Ralph Wilson Park
Geosyntec is a member of the multidisciplinary Ralph Wilson Park (RWP) design team led by Michael Van Valkenburgh Associates, Incorporated. The park is a key part of the revitalization of the City of Buffalo.
Geotechnical Laboratory Testing, Cone Penetration Test Processing, and Reporting
Ocean Wind is New Jersey's first utility-scale offshore wind farm. The wind farm will consist of nearly 150 turbines and will be constructed approximately 15 miles off the coast of southern New Jersey.
Offshore Cone Penetration Testing and Sampling Support
Ocean Wind is New Jersey's first utility-scale offshore wind farm. The wind farm will consist of nearly 150 turbines and will be constructed approximately 15 miles off the coast of southern New Jersey. Ocean Wind is scheduled to be operational in 2024 and ultimately will supply 1,100 megawatts (MW) to more than 500,000 homes.
Flagler Memorial Bridge Micropile Underpinning of Bascule Piers
The aging Flagler Memorial Bridge suffered from detrimental settlement caused by vibratory installation of steel drilled shaft casings for a new, immediately adjacent bridge crossing. Deformations of the existing bascule piers were so significant that the leaves would not properly align, forcing the Florida Department of Transportation (FDOT) to close the existing bridge, constructed in 1927, and plan for design and implementation of underpinning for stabilization.
Barge Decommission, Dismantle and Dispose Project
The U.S. Army Corps of Engineers (USACE) awarded a $35 million contract to decommission, dismantle, and dispose a nuclear reactor installed on a barge in Texas. A few days after a crane was erected on a single layer of lattice crane mats (and while the crane was stationary) subsidence of approximately 3-1/2” was noted below the west crane mat with no observable subsidence below the east crane mat. The crane was removed and a ground improvement program was implemented including installing dry soil cement mix piers (piers) to improve the bearing capacity. Due to obstructions during drilling, only 75 percent of the piers were installed to the design depth. The project required use of this crane for a period of about one year and its successful deployment was critical.
AGE Biomass Renewable Energy Plant
DCO Energy, LLC (DCO), was the design-build contractor for the $200M, 50 MW AGE Biomass Renewable Energy Plant in Albany, Georgia, a project jointly developed by Constellation Energy (Exelon) and Proctor and Gamble Co., Inc. The original foundation design by a local consultant had resulted in a very conservative working pile resistance and a significant number of costly battered piles. Therefore, new steel H-pile foundations were proposed.
PG&E Humboldt Bay Power Plant Unit 3 Nuclear Decontamination and Decommissioning
The Pacific Gas and Electric (PG&E) Humboldt Bay Unit 3 nuclear reactor went online in 1963, but was only operational until 1983, when functional, safety, and seismic concerns led to a shutdown. Decommissioning of Unit 3 was approved in 2009, and began in 2012. Unit 3 decontamination and decommissioning (D&D) is being performed by CB&I under an EPC contract with PG&E. Work required for removing the Unit 3 caisson, whose bottom is founded at Elev. -80.5, 93 ft below existing ground surface, included a deep hydraulic cutoff wall and construction of a dewatering system.
1601 Wewatta Support of Excavation
Zocalo Community Development and Hines, developers of two adjacent sites in the booming real estate market of Denver’s Central Platte Valley, required a full design review for a 43 ft deep excavation for Hines’ new site at 1601 Wewatta. The 1601 Wewatta site is immediately adjacent to the recently constructed Cadence Apartments site, a 13-story mixed commercial and residential structure developed by Zocalo.
Feasibility Study for Renewable Energy Technologies at the Lorton Energy Park
ESI’s long-term vision is for the landfill property to transition over the remainder of its operational and post-closure life from a landfill disposal facility to a state-of-the-art renewable energy park. To extend the operational life of the Lorton Landfill, ESI plans to increase the disposal capacity by constructing a mechanically stabilized earth (MSE) berm around the perimeter of the landfill footprint. They retained Geosyntec to conduct a detailed feasibility study on the phased implementation of various renewable energy technologies (RETs) in conjunction with the planned expansion. The purpose of the feasibility study was to evaluate the technical and financial feasibility, aesthetic qualities, and regulatory and public acceptability of four RETs: solar, wind, biogas methane, and geothermal (GT) technologies. The feasibility study provides the basis for financial planning for developing the renewable energy park, particularly with regard to the optimal timing for deployment of RETs.
Shaffer NPL Landfill Solar Redevelopment
The Shaffer Landfill is a closed, two-lobed industrial and municipal landfill located within the Iron Horse Park Superfund Site. Construction of the landfill cap (for which Geosyntec provided independent construction quality assurance services) was completed several years ago, with ongoing post-closure operation and maintenance. An energy developer identified the exposed lobes of the landfill as potential sites for solar development and retained Geosyntec to conduct an engineering evaluation for the construction of a fixed, ground-mount, photovoltaic (PV) solar panel system.
