Project Summary

Services Provided: Construction Management & Inspection
Trap and haul fish passage programs are often very complicated and expensive, and they almost always come with surprises during construction that were not anticipated during planning and design.
That’s why a trusted and experienced partner like MacKay Sposito is so vital. We understand the risk associated with retrofitting aging structures, coupled with strict in-water work windows. As your owner’s representative, we look for creative solutions to preserve the original timeline and costs.
