As Multnomah County officials seek to downplay cost overruns on the Sellwood Bridge, public records obtained by The Oregonian/OregonLive highlight a key underlying problem: Officials budgeted significantly less money for unexpected costs than government and industry standards call for.
The $307.5 million project includes a 4 percent contingency fund, or $12 million. Federal agencies such as the U.S. General Services Administration recommend contingencies of 7 to 10 percent.
The Associated General Contractors of America says 5 to 10 percent is typical for projects using the county's contracting method for complicated projects, which brings the general contractor onboard at the beginning instead of waiting until designs are done.

Construction for a private residential project will impact traffic on SE Tacoma St. near SE 6th Ave. from 9 a.m. to 3 p.m. January 14 - 15 and possibly on January 16. Two traffic lanes on Tacoma St. will be closed during excavation for a sewer line. During work hours flaggers will direct traffic on a single open lane on the south side of Tacoma St. This work is not part of the Sellwood Bridge project but it will add to traffic congestion near the bridge. Travelers may want to consider alternate routes such as the Ross Island Bridge to avoid delays during this work.
Springwater Trail: Flaggers will control traffic on the trail under the bridge between Spokane St. and Umatilla St. during work hours the week of Jan. 12 while the drilling contractor accesses the east abutment area. Trail users may be delayed a few minutes at times. This section of the trail will be closed for two weeks starting January 19 when the foundation shafts for the abutment are being drilled. A detour using SE 7th Ave. will be posted during the closure.
Hwy. 43 lane closures: The outside southbound lane of Hwy. 43 is closed weekdays and Saturdays until 4 p.m. between SW Taylors Ferry Road and the bridge while the contractor works on the west side of traffic lanes.
