The United States Army Corps of Engineers, Portland District, will accept sealed bids in late June for the refurbishment of three roller chain penstock gates at Lookout Point Dam on the middle fork of the Willamette River in Lowell, OR. The ARRA-funded project includes shop-coating the gates and replacing roller chains, sheaves, wire ropes, seals, and sacrificial anodes. The contractor will transport one gate per year to an offsite facility for repairs and coatings application, which will be completed during the reservoir water level-determined periods of September to mid-January over the next three years.
The coatings work, which requires SSPC-QP 1 and QP 2 certification, includes lead-based paint abatement. The gates will be abrasive blast-cleaned to a White Metal finish (SSPC-SP 5), thermal-spray metalized with 85/15 Zinc/Aluminum, and coated with a moisture-cured urethane system. The contractor must employ a third-party NACE-certified coatings inspector to oversee the surface preparation, metalizing, and coatings application.

The University of California at Berkeley has awarded a contract to Bayview Painting & Construction (Burlingame, CA) to paint exterior building surfaces at its Haas School of Business. Designed by Charles Moore of Moore Ruble Yudell, the 200,000 square feet "mini-campus" opened in 1995. The three connected buildings were constructed around a courtyard to create a sense of community and encourage interaction among students and faculty.
The project includes cleaning, patching and painting exterior pre-cast concrete surfaces with a Green Seal Certified low-VOC system. The contract is valued at $356,000.
