Civic Center Special Task

Interstate Engineering had a request in the summer of 2019 from the Jamestown Civic Center to assemble plans, specifications to place out to bid the removal and replacement of caulking and expansion material for the wall panels on the Civic Center. The wall panels are concrete double tees with a 1”+/- gap between them. Inside the civic center, there was visible daylight filtering in between the joints. We assembled the plans and specifications using photos and the original set of plans for the civic center from 1971. Project bidding took place in July 2019 with the project awarded in August.

Sticky Construction, Inc, of Thompson, North Dakota, was awarded the project. The caulking sealant that was used was SikaHyflex – 150 LM. The contractor removed and replaced 4,135 LF of caulking and backer rod.
As technology advances, so does the capability of caulking. The current formula means installation can happen in temperatures as low as -20°.

Current technology allows for caulking to be installed in temperatures as low as -20°. It is necessary to make sure that the contractor verifies that the surface is not wet and frost-free for the adhesion of the caulk. The original caulking was thought to have been 20 years old. The contractor believes the new caulking will endure longer than 20 years.

The backer rod used is OCFOAM Open Cell Backer Rod. This product has a temperature limit of -45°.

The project was completed in September 2019.

Travis Dillman, PE, served as Principal Engineer on the Project. Todd Langbehn was the drafter, specification writer, and project manager during the construction of the project.
