Complicated work will take a month

Construction on Southwest Matrinazzi Avenue will begin later this month. Downtown traffic (the yellow line) will be diverted around Martinazzi Avenue by Nyberg Street. Thru traffic (the blue line) will have to use Boones Ferry Road.Trips to the Tualatin Public Library, municipal offices and several businesses downtown are about to get more complicated over the next month.

Slated to begin Aug. 12, the Martinazzi Avenue Project involves significant infrastructure updates, including the replacement of the waterline that runs from Nyberg Street and under the Tualatin River; the replacement of the sewer line that runs from Seneca Street to Boones Ferry Road; replacing the pavement that runs north of Nyberg Street to Boones Ferry Road; installing a new traffic signal at the intersection of Nyberg Street and Martinazzi Avenue; and updating the catch basins along the road.

The project will be handled by Kodiak Pacific Construction. In April, Tualatin city councilors unanimously passed a resolution to bypass their standard bidding procedure on such projects, which normally gives preference to the cheapest bid. As the designated review board, the council opted instead to grade bidding companies on a more specialized set of criteria, arguing the Martinazzi Project required “highly specialized work” in the areas of water line boring and signal installation.

The resolution emphasized that an alternate selection method would allow the city to choose a contractor who “can ensure the coordination of construction timing and requirements of continued mobility near the site,” according to the resolution.

Three companies applied after a publicly advertised call for bids in May. The city had estimated the project would cost $1.6 million, and Sherwood-based Kodiak Pacific issued a bid of $1.44 million for the project.

Kodiak Pacific previously served as general contractor for the $23 million I-5 Preservation Project, which focused on repaving, constructing additional lanes and the installation of a sound wall on the freeway’s west side.

The stretch of Martinazzi Avenue between Boones Ferry Road and Nyberg Street will be closed from Aug. 12 to Sept. 12. To access the library or city offices, drivers are advised to enter the former Kmart shopping center from Nyberg Street, or to park at the lot across the street, between Boones Ferry Road and Nyberg Street.

During this time, the library will extend due dates so no penalties will be issued on materials due July 22 through Sept. 12. To accommodate patrons, library materials will be accepted at Haggen, 8515 S.W. Tualatin-Sherwood Road, as well as at all other Washington County Cooperative Library Services branches.
