Taylor Hill Reservoir Structural Eval and Reno Project Wins Award

(raSmith: raSmith Wins ACEC Engineering Excellence Award)

raSmith has received a 2018 State Finalist Award from the American Council of Engineering Companies (ACEC), Wisconsin Chapter, for the Taylor Hill water reservoir project.

Sheboygan Water Utility contracted with raSmith to complete the structural evaluation and lifecycle cost analysis of the Taylor Hill water reservoir in Sheboygan, Wis. The Utility needed to determine if the water reservoir, an 87-year-old historic structure, should be rehabilitated or completely replaced. With a four-million-gallon capacity, the sizable structure is an integral part of Sheboygan’s water distribution system as well as an iconic structure within the City of Sheboygan.

Taylor Hill Water Reservoir

Taylor Reno Project
LiDAR (3D laser scanning) assisted our surveyor in documenting deficiencies of the entire reservoir. This captured thousands of pieces of data.

To accurately and efficiently complete the evaluation, raSmith’s staff used a unique combination of traditional and contemporary equipment and methods to quantify the water reservoir’s structural deficiencies. The structural engineer physically assessed the structure, working from an aerial work platform of heights of 30-plus feet from the ground, and spray painted areas of deficiencies. An raSmith surveyor then used LiDAR (3D laser scanning) to document deficiencies of the entire reservoir, which captured thousands of pieces of data that correlated with the spray-painted deficiencies. The data and lifecycle cost analysis led the Utility to choose to rehabilitate the structure and extend its useful life by 25 years.

Additional Information
The Taylor Hill water reservoir evaluation project represents methodology that enabled the Utility to gain a quick understanding of the reservoir’s issues so that a cost-effective solution could be chosen based on reliable and highly accurate data. The exact methodology employed on this project, including a hands-on structural inspection, structural assessment, LiDAR scanning, and lifecycle cost analysis and reporting, can be applied to many other structures of various sizes and complexities that require structural evaluation or rehabilitation.

From the beginning, the project was viewed as an analysis, not a repair. The purpose was to evaluate rehabilitation and ongoing maintenance options. All deficiencies were evaluated and documented; alternatives were developed, which ranged from leaving the structure as is to complete demolition and replacement. Using the lifecycle cost analysis, the Utility determined that the most sustainable and economical option was to repair portions of the reservoir. The evaluation and repair work will help maintain the City’s water distribution system as designed and ensure clean water within the community.

ACEC Awards
Each year, ACEC–Wisconsin awards top projects for their high level of quality and client satisfaction. The award ceremony will be held on March 23 at The American Club in Kohler.
