  • Hargus Lake Intake Renovation<p>ODNR

    Hargus Lake Intake Renovation


    The Ohio Department of Natural Resources (ODNR) requested that Kabil Associates perform a site visit and evaluate the subject structure. The primary concern was deterioration and structural adequacy of the intake structure, safe location of access stairs, and improvements of overall condition.

    Our team of Structural Engineers visited the site, performed a preliminary analysis, and determined that the appropriate scope of work was to perform a detailed investigation, propose solutions, and statements of probable cost.

    The optimum solution was to partially replace and structurally repair the remaining deteriorated concrete. The report was submitted to ODNR. Kabil Associates prepared detailed construction drawings and provided bid documents to ODNR. Field evaluation of work performed was executed by Kabil Associates as well. On completion of the construction phase, a few cracks were observed, and further testing and review was undertaken and it was concluded that the cracks are minor and the structural strength is intact.

    There were significant challenges to the execution of the work due to structure being submerged. The design and execution demonstrated a clear understanding of the specific needs for this project, such as the submerged structure, and taking account for other environmental exposures of structures.

  • St. Mary's Church<p>Columbus, Ohio

    St. Mary's Church

    Columbus, Ohio

    This iconic historical church, located in German Village, was built in 1868. It is the tallest structure in German Village and is listed in the U.S. National Register of Historic Places. The roof framing utilizes heavy timber scissor trusses. The thrust imposed from these trusses had, over many decades, caused partial displacement and damaged and/or weakened the masonry bearing walls. This deterioration and bowing of the walls allowed sagging of the trusses, which caused further issues with the existing slate roof.

    Kabil Associates provided a solution to stabilize the trusses in place and allowed the parish to maintain the historic ambiance of the ceiling. The masonry buttresses were stabilized by inserting a steel WT column that was cut in two and inset into the buttress to preserve the historical aesthetics.
