(HWA)proposal <br /> to the City of Everett(City) for installing four ground water piezometers around your <br /> water reservoir No. 3 located at 6107 Berkshire Drive, Everett, Washington. Below, we <br /> present our scope of work and project cost estimate. <br /> We understand you plan to drain the 24 million gallon reservoir for maintenance and <br /> need to know the ground water levels to avoid uplift of the membrane liner and/or <br /> concrete bottom slab. HWA proposes to drill and install four ground water piezometers <br /> around the reservoir, along the perimeter access road. The proposed scope of work <br /> includes: <br /> • Retain a licensed well drilling sub-contractor to drill and install the wells <br /> • Coordinate with the City to schedule the field work <br /> • Clear underground utilities before drilling by calling the Utilities Underground <br /> Location Center, and checking utility plans provided by the City. HWA will not <br /> be held liable for damage to utilities or other underground structures not defined <br /> or located for HWA by the City or the Utilities Underground Location Center. <br /> • Drill, install, and develop four ground water piezometers (monitoring wells), up to <br /> 35 feet depth. Alternately, and based on concurrence with the City,three wells to <br /> 46 feet depth may be installed, or some other combination of wells and depths <br /> that meets the approved budget. <br /> o Wells will be constructed of Schedule 80, 2-inch diameter PVC pipe <br /> o Each well will have 10 feet of 0.010" mill slotted 2-inch diameter PVC screen <br /> o Screened section will have a sand filter pack filling the <br /> annulus 21312 30th Drive SE <br /> Suite 110 <br /> Bothell,WA 98021-7010 <br /> Tel:425 774.0106 <br /> Fax:425.774.2714 <br /> www.hwageo.com <br />
