Location: Fairbanks, Alaska
Value: $9 million
Scope of Work: Design Permitting Construction Logistics
Through technical and managerial excellence, STG Pacific successfully completed a $9 million design-build project to remove and replace Fort Wainwright’s 70-year old, World War II era Bailey Bridge. Overcoming multiple changed conditions, the COVID19 pandemic, and unforeseen contaminants, STG Pacific achieved what they had proposed as a fast-tracked schedule—beneficial occupancy of this mission critical bridge within a single Alaska construction season. STG Pacific worked with Michael Baker International and Hamilton Construction, combining years of expertise in AKDOT&PF bridge design and construction, civil work, and project management to deliver a quality project.
The bridge. STG Pacific constructed a 266-foot-long, three-span structure composed of six, 66-inch decked bulb-tee girders supported by reinforced concrete pile caps over the piers and semi-integral abutments and founded on deep driven piles.
Project management. STG Pacific leveraged project management experience/expertise from the repair/replacement of three bridges in the last three years in Alaska and California. This experience enabled us to pivot quickly in response to a series of changed conditions to avoid impact to schedule. Ultimately, our team never missed a day on the job and achieved on time beneficial occupancy of the bridge.
Innovation. STG Pacific has built a reputation for the innovative use of cranes to demolish/repair/replace mission critical bridges. For Bailey Bridge, we used two large cranes in two distinct locations on either side of the river to eliminate working in-water, temporary work trestles, fish window impacts, and the high-water conditions. Our innovative approach and winter demolition of the bridge also reduced safety risks and potential impacts to the river habitat.
Safety management and record. STG Pacific performed the project above and adjacent to a busy recreational river, and adjacent to an active golf course. We completed this complex project with no lost time incidents.
Sensitivity to the environment and surroundings. STG Pacific worked collaboratively to successfully minimize impact to the Chena River—a state recreational area used by boaters and kayakers, as well as the adjacent Chena Bend Golf Course, ranked the #1 Golf Course in Alaska multiple times by Golf Digest.
Sustainability. STG Pacific deconstructed the Bailey Bridge using the largest crane in Alaska and placed the bridge components into secondary containment for remediation. We then donated the components to the Alaska Interior Land Trust to build pedestrian bridges within the Chinook Conservation Park. This 70-year old bridge will now have another ~50+ years of life in the Fairbanks community.
