Bay Area Hospital

Bay Area Hospital

The expansion of the Bay Area Hospital, located in Coos Bay, Oregon was a much needed modern upgrade to the existing 40-year-old three story facility. This area

includes a new critical care unit, a new 30 bed medical surgical unit and a new outpatient area. The addition is located to the north end of the current building.

Bay Area Hospital

The new hospital expansion added 110,000 square feet, with four levels of slab on metal deck, and three core towers. Concrete placement was a challenge on this

project, as the plant was 50 minutes away from the jobsite.

Bay Area Hospital

Admixtures were dosed onsite due to the travel time between the plant and the project. A hydration stabilizer was added to the mix designs to help with this issue, as well.

Bay Area Hospital

The exterior of the building was designed to conform to the existing building finishes.

Bay Area Hospital

A multilevel atrium space was included in the design to help allow people to become oriented upon arrival.

Bay Area Hospital

ADA issues were addressed at the exterior entrance of the building by adding white cement at the tactile warning areas. To achieve the desired color the bags of

white cement was added to the concrete trucks onsite.

Bay Area Hospital

Overall, this project used 6,053 cubic yards of concrete for successful completion.
