On October 7, 2019, Christopher Kottra, Associate Principal at Building Technology Consultants, Inc. (BTC), will be presenting the following topic: “474 N. Lake Shore Drive – Parking Garage Renovation & Expansion Joint Repairs” at the Sealant Waterproofing and Restoration Institute’s 2019 Fall Technical Meeting to be held from October 6-8, 2019 in Charleston, South Carolina.

The joint presentation with Mr. Bill Leonhard from Allied Waterproofing, Inc. will be a case study of the parking garage repair project completed at the 474 North Lake Shore Drive Condominium Building in Chicago. The project won the SWR Institute Trinity Award in 2016.

The restoration initiative at 474 North Lake Shore Drive was broad and included numerous technical and logistical challenges. Chiefly among these were providing dust enclosures for the 15-story structure, performing 15 different types of concrete repairs, replacing expansion joints, and installing sealant and traffic-bearing membrane. Despite additional unforeseen conditions, the project was completed two weeks ahead of schedule due to the strength of the team and ongoing collaboration with the building’s representatives.

The mission of SWR Institute, a non-profit corporation, is to elevate the standards of practice for the sealant, waterproofing, and restoration industry through education and fellowship. Through SWR Institute, members gain opportunities to learn about current trends and new products, exchange ideas, discuss new methods of application, and network among fellow professionals.
