Geosyntec developed an instrumentation and data management system to track, analyze, and visualize the ongoing lock removal. The system uses GIS technology to manage data associated with blasting, anchor installation, pile and wall installation.
Geosyntec built a system to import data collected during grouting operations and automatically generate progress drawings, resulting in significant time and cost savings for the Contractor.Folsom Dam is a concrete gravity dam on the American River in northern California. Located at the juncture of the north and south forks of the American River, the dam and its reservoir, Folsom Lake, are part of the Central Valley Project, a multipurpose project that provides flood control, hydroelectricity, and irrigation and municipal water supply to the residents of Sacramento County, CA. We supported DrillTech by importing automated grout curtain data and generating progress drawings per the USACE specifications.
Geosyntec developed and deployed a web-based application to track, analyse, and visualize data collected during grouting operations. This application syncs to on-site grout monitoring equipment to immediately view grout takes and other data in plan and profile views, and in as-built drawings.The Rough River Dam in Kentucky is an earthen dam rising 135 feet high and spanning 1,590 feet with a maximum capacity of 334,400 acre-foot and has been maintained by United States Army Corps of Engineers Kentucky District since 1959.
An ephemeral drainage channel in La Jolla, California became severely incised due to stormwater and non-stormwater runoff from urban development that has increased over the last several decades. The progressive erosion of the channel threatened the stability of adjacent residential properties initiating a need for an emergency repair project.
Geosyntec's client, a power plant in Ohio, generates electricity from two, 1,300-MW, coal-fired units. In anticipation of upcoming federal coal combustion residuals (CCR) regulations, the client decided to initiate closure design for a 300-acre fly ash pond. The site also features a high hazard dam. Acid mine drainage (AMD) from around the reservoir reduces the pH of the water and is currently treated in the reservoir.
Brunner Island is a three-unit, coal-fired plant owned by PPL Generation, Inc., and located on the west bank of the Susquehanna River. The plant constructed a 130-car rail line extension and storage yard atop a closed coal ash pond. Geosyntec was retained to design and implement a test fill program, prepare and implement a field sampling program, and analyze and conduct preliminary analyses of foundation performance.
Geosyntec has had a strong and continuous involvement in engineering projects at TVA Kingston since the 2008 geotechnical failure. Our involvement includes the following and serves as a demonstration of our experience with coal combustion residuals (CCR) management, disposal, and associated activities.
Geosyntec provided comprehensive services to Santee Cooper at the Winyah Generating Station to assist the facility with compliance with the pending implementation of the federal Coal Combustion Residuals (CCR) Rule and Effluent Limitation Guidelines (ELGs).
Tesoro Alaska Petroleum Company has an oil refinery in Kenai, Alaska, on a bluff approximately 100-feet above the shores of the Cook Inlet. Historic practices at the site contributed to the presence of refined petroleum products in groundwater migrating toward the shoreline bluff. Tesoro retained Geosyntec to design and build a system to collect impacted groundwater and redirect it to a treatment facility.
The Santa Clara Valley Water District's Dam Safety Review Project (DSRP) is provides an independent safety review and evaluation of four California dams: Anderson, Almaden, Calero, and Guadalupe.
