| Dam safety Exhibitor updates
Dam Safety 2024, the premier educational and networking event for the dam safety industry, will be held from September 22-26 in Denver, CO, at the Colorado Convention Center. Building on the success of last year’s conference with nearly 1,200 attendees, this year’s event marks the 40th Anniversary of ASDSO’s National Dam Safety conference. Here, we spotlight recent news from some of the key exhibitors
GEI Consultants
The City of Escondido has selected GEI Consultants to provide Construction Management (CM) services for the city’s Lake Wohlford Dam Replacement Project. GEI will manage the construction of this new roller compacted concrete dam with a team of CM experts, who bring decades of experience required to manage this large, complex, and essential dam replacement. Located 6.5 miles northeast of Escondido,
the Lake Wohlford Dam is used for flood control, municipal water supply, recreation, freshwater habitat, and wildlife habitat. But a 2007 seismic analysis found that the upper portion of the dam embankment was seismically unsafe. As a result, the reservoir storage has since been limited to just 40% capacity. This dam replacement project will allow the city to restore the lake to its full level, increasing water storage capacity and expanding the lake’s surface area for recreational users.
As Construction Managers, GEI’s experts will use their extensive experience to manage delivery of the project, including controlling cost, quality, risk, and schedule. GEI will proactively work with the city, contractor, project designer, California Department of Water Resources, Division of Safety of Dams (DSOD), environmental compliance team, the surrounding community, and other key stakeholders to deliver a successful project. “With our combined decades of experience,
local presence, and lessons learned delivering similar projects, we understand the city’s needs as well as the importance of meeting the intent of the dam’s design and how to construct it,” said Jerry Reed, GEI’s principal-in-charge for the Wohlford project. “We look forward to working with the contractor, designer, the DSOD, and other stakeholders to deliver this important project for the city and their residents.” “The City of Escondido is pleased to have GEI and their experienced team managing construction of one of our most important projects,” added Randy Manns, Utilities Construction Project Manager for the City of Escondido. “Once complete, the new dam will ensure safe and reliable water supply for City of Escondido residents as well as return full recreation use to the region.”
GZA GeoEnvironmental Inc.
GZA has been retained by the Connecticut Institute for Resilience and Climate Adaptation (CIRCA) under the Resilient Connecticut 2.0 Program to perform a comprehensive study of options to mitigate flooding on the Yantic River in Southeastern Connecticut. Working with CIRCA, the Southeastern Connecticut Council of Governments (SCCOG), the City of Norwich, and the Towns of Bozrah and Franklin, GZA will serve as prime consultant on the initiative to advance community-driven and conceptual design climate adaptation projects between the Fitchville Pond Dam in Bozrah and Uncas Leap in Norwich. Severe weather and heavy rainfall in January 2024 led to flooding and a partial evacuation of the community downstream of the Fitchville Pond Dam. GZA’s partners on the project are Stantec and DREAM Collaborative. The project will include creation of a
Citizen and Technical Advisory Committee led by SCCOG and CIRCA, current and future conditions analysis, development of a suite of flood mitigation options and conceptual designs for priority areas, identification of potential funding sources, conducting benefit cost analysis required for federal grant eligibility, and preparing an implementation plan for the proposed adaptation strategies. GZA President and CEO Patrick Sheehan said: “GZA and our partners look forward to working with stakeholders in Norwich, neighboring towns, and CIRCA and SCCOG to identify ways to improve resilience for residents and business owners along the Yantic River corridor and protect lives and property.’’
Kleinschmidt Associates
Kleinschmidt Associates has been selected by Patriot Hydro, LLC to provide engineering and permitting services for the Jackman Penstock Replacement Project located in Hillsboro, New Hampshire. The project entails designing and replacing approximately 1150ft of an outdated wood stave penstock at the Jackman Hydro Station with a new half-buried fiber-reinforced polymer (FRP) penstock. Additionally, a 72ft section of the penstock, currently supported by a steel bridge over the North Branch River, will be replaced with a new welded steel section
supported on ring girders. The comprehensive scope of work also includes the design of a new reinforced concrete retaining wall to replace an existing crib wall adjacent to the penstock. Kleinschmidt will provide Patriot with a range of services, including wetland delineation, permitting, agency consultation, and the creation of design drawings and specifications. Engineering support will also be provided during the bidding and construction phases. “We are excited to partner with Patriot Hydro on the Jackman Penstock Replacement Project. This initiative allows us to provide innovative engineering solutions and reinforces our commitment to sustainable infrastructure development,” said Eric Turgeon, Project Manager at Kleinschmidt Associates. “Replacing the aging infrastructure with advanced materials like FRP and steel ensures both environmental and operational efficiency for years to come.” The project began in May 2023 and has an estimated completion date of Fall 2025.
WSP
Multidisciplinary professional services consultancy WSP and Binnies, whole lifecycle water and environmental services provider, have been appointed in joint venture to the Environment Agency’s (EA) 2024 MMF to deliver national, catchment and local scale flood risk mapping and modelling. WSP and Binnies are amongst six delivery partners supporting the national framework at a value of £52.5 million over three years, with the option of an additional year at a value of up to £17.5 million. Building on the existing successful relationship WSP and Binnies have with the EA, they will draw on the expertise of their respective water teams, providing a range of services including National Modelling, Fluvial, Open Coast, Coastal Erosion and Tidal Modelling, Surface, Ground Water and Sewerage Modelling, Survey and Mapping. The work carried out under the framework will be critical in providing the evidence required to understand the impact of our changing climate. The EA will then be able to update their long- term investment scenarios to produce more detailed insights into future flood and coastal risk which in turn will help inform the pipeline of future risk management requirements.
