PURPOSE: To obtain Executive approval of Change Order 23 to Marpac Construction.
BACKGROUND: The County and Marpac Construction entered into an agreement on December 18th, 2024, for the construction phase of the New Start Center of Everett. Marpac Construction and the plumbing subcontractor, Streamline, air pressure tested the western third of the cold-water supply lines at the back building for one week. During the course of the week, they discovered the system is a combination of copper, galvanized steel, and plastic piping. The three plumbers repaired approximately 45 leaks. Marpac aided in uncovering areas and listening for leaks. Hearing air leaks in the system proved difficult due to the noise from Interstate 5 and the low pressure they were able to maintain. The system would need to hold 120 psi of air pressure in order to consider filling with water at 80 psi, normal operating pressure. By the end of the week, this portion of the system would not hold 10 psi of air pressure. This level of pressure could be achieved by friction along the length of the pipe. Basically, spending over 120 labor hours of work on 1/6 of the existing system resulted in no noticeable improvement. At this time, it is assumed the other 5/6 of the system will have similar issues. There is no way to know how many leaks will be found or how long repairs will take in make the system operable. Even if all of the current leaks are found and repaired, there is no way to guarantee a new leak will not develop within the first few weeks after placing the system back into operation. Newly developed leaks would be assumed to ...
