Tualatin Sherwood Corporate Center

Sherwood, OR

Kerr Contractors partnered with the developer in the pre-construction phase for this 32 Acre, $70 Million dollar development for 18 months to help bring the project to reality. Topographical constraints require  Kerr Contractors to remove nearly 1,000,000 cubic yards of earth from the site to create 535,000 square feet of building pads for commercial use. Team Kerr, with industry partners, is constructing three separate elements of design-build retaining wall systems to make room for the building pads and parking areas. Project challenges included a wet weather start to construction, BUT within a matter of days, the site was prepared with the necessary erosion measures to allow work to proceed throughout the winter. The emphasis during pre-construction was how to best use the onsite rock excavation to produce spec aggregates for the project. Risk-sharing between the developer and the construction team supports accelerated project delivery and produces an outstanding opportunity for all parties.

Slip Lining Existing Effluent Line

Newport, Oregon

This was a design-build project. Work included slip lining approximately 3,750 of ocean effluent line at Nye Beach. Kerr Contractors worked directly with the Owner’s engineer to design and determine means and methods for slip lining the existing effluent line. Work involved staging and welding 20″ HDPE pipe along a heavily populated beach during peak tourist season. Construction required significant coordination with Owner, City of Newport, State Lands and local businesses to develop a workable schedule for construction. During periods of favorable tides, Kerr Contractors worked 24X7 to successfully complete the slip lining. Normal paper plant operations were not impacted during construction.

Low Head Flow Pipe

Hood River, Oregon

This was a best-value project. Work included installation of 7,500 lineal feet of 36″ and 6,240 lineal feet 42″ low flow pipe in a former open canal to enclose system and reduce leakage. The Owner scheduled all pipe to be installed outside normal irrigation season. More importantly, all pipe must be installed within one – two week period. The Owner selected a contractor based upon their ability to demonstrate past experience and the ability to perform all work within the required time frame. Kerr Contractors was the selected contractor.

Dawson Creek Pump Station

Hillsboro, Oregon

CleanWater Services, the largest Sewerage Agency in the Portland Metropolitan area, constructed a new pump station and twin force main. This was a best-value project. CleanWwater Services selected a contractor based upon their experience in pipeline and pump station construction. Other requirements of the project included the installation of a secant pile wall to shore the pump station during excavation and construction, as well as act as a launch pit for a 42″ micro tunnel below Brookwood Parkway. Another significant project requirement was the construction of a pipe bridge over the active Tri-Met light rail tracks. Kerr Contractors was the selected contractor for this work.

Effluent Repair

Newport, Oregon

This was a best-value project. Work included replacing an existing wastewater effluent at Nye Beach. Kerr Contractors was performing a similar repair project for the City of Newport. The Owner, familiar with the project, initiated negotiations with Kerr Contractors regarding performing this effluent repair. The relationship with the Owner and the engineer allowed Kerr Contractors to collaborate directly with the Owner’s engineer to design and install a new effluent line. Work included replacing a welded steel line with a new line on a public beach during the peak tourist season. The Owner’s previous experience with Kerr Contractors performing similar work was the deciding factor in the evaluation process for this turn-key project. Construction required significant coordination with Owner, City of Newport, State Lands and local businesses to develop a workable schedule for construction. Kerr Contractors worked all hours during favorable tides to keep the papermill in Toledo online.
