At its annual awards ceremony, the American Council of Engineering Companies – New Hampshire Section (ACEC-NH) recognized highly impactful, innovative, and successful projects completed by members of the New Hampshire engineering community. The awards are intended to celebrate projects that demonstrate innovation, make visible and positive impacts on communities, are delivered on time and within budget, and advance the state of the engineering art in New Hampshire. Led by D&K teams, the Hooksett Nature-like Fishway (Hooksett NLF) on the Merrimack River and the West Hopkinton Penstock Rehabilitation received honors at this event.
The Hooksett NLF received an Honor Award for Engineering Excellence for implementing a structure that enables salmon, trout, sturgeon, and eels to travel up the river and past the Hooksett Hydroelectric Station. The built project includes an inflatable gate with six concrete weirs with notches—enabling the owner to control flows and providing access both for fish that travel using vertical climbing as well as those that rely on horizontal/lower angle climbing surfaces. The design accounted for straightforward construction on a large body of water and included significant input from NOAA, NHDES, and US FWS, resulting in completion of a key step in the FERC relicensing process.
The West Hopkinton Penstock Rehabilitation received an Honor Award for Engineering Excellence for replacing a key component of this hydroelectric power generation facility without disrupting the traveling public. Originally a wood stave penstock that had received slip-line based repairs, the penstock conducts flows beneath a state highway from the intake structure to the powerhouse. The project’s complexities included using and evaluating a range of cutting-edge forensic tools to understand the condition of the existing penstock while also developing repair practices that avoided open-cut construction. Our team’s analysis found that the existing interior structure and annular space around it could be strengthened using shotcrete and a new lining structure that would fit within the existing space but would allow equivalent flows by constructing a significantly smoother interior surface.
