Project Builds Retention Wall, Excavation Support

August 11, 2010

DBM Contractors Inc. has completed excavation support for the Highline Medical Center's Birch Wing Addition.

The $900,000 shoring project required DBM to build a permanent retaining wall to allow for the building and site changes. To complete the 343-foot-long permanent wall, DBM installed 41 soldier piles, 57 double corrosion-protected tieback anchors, and 5,100 square feet of timber lagging. In addition, DBM installed 3,568 square feet of temporary shoring for excavation support for the building expansion, which included installing 42 soldier piles and 48 tieback anchors as well as 42 underpinning piles to support the existing structure.

General Contractor/Construction Manager for the project is GLY Construction. The Birch Wing project broke ground in July 2008 and is scheduled for completion in early 2010. When completed, the new 75,000-square-foot facility will house a state-of-the-art Emergency Department, a Patient Care Unit, and space for future diagnostic imaging and lab services. Jim Elliott, principal, and Tyler Tonkin, senior project manager, are leading the GLY project team.
