As a design assist trade partner, we provided value engineering support for the engineering team and budget development for the Owner. As we progressed through the design and permitting of this project, we identified several constructability issues. We were able to apply our local knowledge of available products and expertise with high energy dissipation and underground conductors to provide input toward solutions that supported completing the project design ahead of schedule. In addition to our design phase support, we provided earthwork, site utilities, structural excavation and several thousand linear feet of electrical trenching in order to complete the project on-budget and ahead of schedule.

Following our successful engagement on the Constable Energy Project, we provided design-assist support for another energy storage project. We provided cost estimates and supported development of various underground improvement options that addressed this project’s additional complexities from contaminated soils, liquifiable soils, drilled ground improvements, cement treated soils and the facility’s proximity to the Willamette River. 

Our construction phase effort included excavation and grading efforts to support multiple different trades, including the concrete team, crane crews, boring of medium voltage feeds, site electricians and overhead transmission contractors. Our ground improvements included structural excavation for geopiers, grading for the concrete crews, and several thousand linear feet of electrical trenching. We worked in close coordination with the GC and our trade partners to schedule and sequence this work to maintain a streamlined flow for our teams and our trade partners. 

High water tables and deep excavation needs were a particular challenge for this project. The C&W team managed a significant dewatering effort, leveraging dewatering wells, filtration of contaminated waters and other mitigation methods as we dug deeper,to overcome this complexity. 

C&W also supported the public roadway re-construction of Time Oil Road and access easements. This project was completed complete on-budget and ahead of schedule.

Our team worked through upgrading roughly 5,000 LF of an existing storm sewer system and water quality swales within Burgard Way, maintaining access for Schnitzer Steels, Portland Container, and miscellaneous other businesses. In addition to working through an active roadway and operating industrial facility, our team developed multiple work plans to address unforeseen underground obstructions, high water tables, unstable sands, connection of undocumented storm sewer pipes, and crossing of active railroad lines.

Our team provides on-going and major project support for maintenance and facility upgrades at OHSU. Our work is conducted in an active research facility with hazardous waste and pathogens. Some recent projects have included temporary pumped bypasses for utility relocates and upgrade and excavation of new structures, pens, loading facilities and chemical storage.

C&W was the prime contractor to expand the existing receiving area, flammable storage facilities, stormwater treatment facilities and utility reroutes. We managed a team of eight subcontractors, leading schedule development and weekly OAC meetings. We delivered this project ahead of schedule.

This project repaired a failing sanitary sewer system. Our construction approach included bypassing the live system, connections for unforeseen sanitary sewer laterals, limited work hours and noise limitations to ensure ongoing quality of care for hospital patients. In addition to the exterior construction, we also excavated the basement level of the hospital while maintaining access for hospital staff to support sewer pipe replacement.
