The placement took 8.5 hours and involved 470 cubic yards of 4,000 PSI high-performance concrete with fiber. Fifteen craft employees used a 61-meter concrete pump to do the job.
The work required extensive coordination among the concrete supplier, concrete pump subcontractor, the joint venture quality control, Multnomah County quality assurance and Oregon Department of Transportation inspection teams.
Self-performing concrete construction enables Sundt to further ensure quality craftsmanship and save clients money.
Sundt and joint venture partner Slayden Construction are constructing the new Sellwood Bridge over the Willamette River in Portland, Oregon using a unique “shoofly” approach.The structure replaces a 2,000-foot-long, aging bridge.
The project is scheduled to wrap next year.
