Earth Retention

Location: San Francisco, CA

Project Partner: Hathaway Dinwiddie

Challenge: Underpinning and tower shoring to preserve existing 100 year old, unreinforced brick walls.

Overview: Condon-Johnson was contracted to provide Micro piles for support of the tower shoring and new construction, installation of soldier piles and lagging to shore up street frontage on Bush and Pine streets, excavate deep underpinning pits for adjacent unreinforced brick structures, and provide tower shoring for two unreinforced brick walls 100 feet long by 50 feet high.

Results: Condon-Johnson was able to manage this project creatively to achieve a safe and successful completion within Hathaway-Dinwiddie’s construction schedule by providing the right people, equipment, and materials on time.
