Taylor Hill Reservoir Structural Repair Sheboygan, WI
Originally built in 1933, Sheboygan Water Utility’s four million gallon water reservoir consists of an elevated steel tank supported by a concrete structure below. A hands-on inspection of the concrete structure by raSmith’s structural engineers, including columns, girders and the bottom of the supporting slab was necessary to evaluate its structural integrity and complete a study that would evaluate rehabilitation and ongoing maintenance options.
As part of the hands-on inspection, areas of delamination, spalls, debonding, and cracking were marked with spray paint. raSmith provided 3D laser scanning services and used color static LiDAR to capture these markings. raSmith then created a series of exhibits that illustrated and quantified these distressed areas. In addition, the resulting point cloud data was used to create a deflection map of the bottom surface of the supporting slab to help our engineers identify any excessive deflections.
These exhibits were included as part of an evaluation study that the Utility used in a presentation to the Board of Water Commissioners to gain consensus on the future of the reservoir. Subsequently, repair work was authorized, and the exhibits were included as part of a bid document package which was sent out to contractors to aid them in their estimation efforts.
