Tata & Howard’s Waterbury, CT office completed forty (40) dam inspections and reports for the Department of Energy and Environmental Protection (DEEP) for dams located in the Western District of Connecticut, including fifteen flood control dams. The dams were rated from a hazard classification of ‘C’ to ‘BB’, and were located in urban environments, suburban locations, and rural settings. The construction of the dams varied from earthen embankments to mortared stone masonry to concrete to roller compacted concrete. The spillways varied as well, including ogee spillways, broad crested weirs, intake risers, and a drop inlet structure.
Each report included a description of the dam, inspection checklists, photographs, a sketch of the dam identifying the major features and showing the photo locations, an aerial photograph and location plan, and recommendations for improvements.
T&H staff also provided the DEEP with a cost estimate for the recommended repairs and maintenance at the 23 non-flood control dams, including contingencies for engineering services, permitting, and construction administration support services.
