DBM Contractors this summer finished a $3.7 million excavation support for MultiCare Good Samaritan Hospitalâs new patient care tower and parking facility in Puyallup. Skanska USA Building is the general contractor for the $400 million expansion.

DBM built 30,000 square feet of soil nail earth retention wall with permanent shotcrete facing. The Federal Way-based contractor also installed 24,000 square feet of temporary soldier pile excavation support walls for the nine-story patient care tower and related structures. The job required about 900 soil nails, 180 soldier piles and 95 tiebacks.

A rocket launcher tie-back drill, pictured, was used to install the retaining walls.

When completed in the fourth quarter of 2010, the 350,000-square-foot expansion will house 80 private rooms, a new emergency department, surgical suites, a diagnostic imaging center and medical offices.

The buildingâs envelope — made of brick, metal panels and glass — is under construction, along with interior finish work and rough-ins of mechanical, electrical and plumbing systems.

Skanska also built a 380-car parking garage that is substantially complete.

The hospital project team includes: Clark/Kjos Architects and Giffin Bolte Jurgens Architects, designers; CDi Engineers, mechanical and plumbing engineer; Sparling, electrical engineer; ABKJ, structural and civil engineer; Walker Macy, landscape architect; University Mechanical, mechanical and plumbing subcontractor; and Veca Electric, electrical subcontractor.
