Olmsted Dam


CTLGroup was contacted by Stantec Consulting Services, Inc. (Stantec) regarding a scope of work for laboratory investigation of Olmsted Dam tremie concrete during the the replacement of locks and dam numbers 52 and 53 at the Olmsted Dam. The general scope was to evaluate the materials and properties of the Olmsted tremie concrete mixture to be placed in precast tainter gate bay shells and stilling basin shells. Prior to the construction of these shells, a test shell section was constructed to evaluate the performance of the tremie concrete mixture. During the placement of the test shell section, the tremie concrete mixture reportedly experienced early-age stiffening problems, and CTLGroup evaluated the concrete mixture to identify the cause and developed the correct concrete mixture that was needed for success.
