Wednesday, February 19, 2014

Comment | More

The City of Tacoma, WA, is currently accepting bids for cleaning and coating penstocks, vent stacks and spillway gates—a project estimated at more than $3 million.

Bids are due April 1. 

Scope of Work

The project involves cleaning and coating the exterior of three existing 925-foot-tall penstocks (variable diameter of 9 feet to 10.5 feet) and three existing vent stacks (120 feet tall x 3.5-foot diameter) at Cushman Dam No. 2.

The project also involves coating the upstream and downstream face of two spillway gates (45 feet tall x 40 feet wide) at Mayfield Dam. 

The penstocks and vents will be pressure-washed, hand and power tool-cleaned to SSPC-SP 2 and SP 3, and coated with a moisture-cured urethane system.

Gate surfaces will be spot-power tool-cleaned to White Metal (SP 11), abrasive blast-cleaned to a Near-White finish (SP 10) for upstream and a Commercial finish (SP 6) for downstream, and coated with a moisture-cured urethane system.

Containment will be required to capture the existing lead-based coatings at both locations. SSPC-QP 2 contractor certification is also required.

The contract includes an alternate option for coating the upstream and downstream surfaces of three additional gates for the 2015 fiscal year if funding allows.

The cost range for penstock coatings is $1.5-$1.7 million. The cost range for the spillway gate coatings is $1.8-$2 million. The total cost range is estimated between $3.3 million and $3.8 million.

Penstock coating work is scheduled to begin April 1, and gate coating work is scheduled to begin June 1, 2014.

About the Dams

Cushman Dam No. 2 is a hydroelectric dam on the North Fork of the Skokomish River. It was built in 1930, and its three 27,000-kilowatt generators provide 233 million kilowatt-hours annually to the Tacoma Power system. 

The Mayfield Dam was completed in 1963 and includes an 850-foot-long concrete arch that reaches 250 feet high.
