Site work for a civil project in Astoria, Oregon. Completed plans call for site work for a water / sewer project.

PROJECT DESCRIPTION The intent of this contract is to resand the existing sand filters that process domestic water for the City of Astoria. There are three filters (1, 2, and 3) that are the same size and a fourth (4) which is larger than the first three. The sand filters are located within the City watershed in the hills approximately 12 miles south east of the City. The access into the watershed is restricted with locked gates. The four filters are together in an area above the dam near the reservoir so that the adjacent ground in the area drains directly into the reservoir. The processed water from the filters goes directly into the City water system. The work consists of removing and stockpiling approximately 18 - 24 inches of existing sand from the bottom of the filter, then furnishing and installing approximately 2.0 - 4.5 feet of new sand and capping it with a layer of the previously removed sand. This will require an estimated 10,400 tons of new sand. While work is being completed on one sand filter, the remaining three sand filters must remain operational.The quality of the watershed and the operation of the existing filters must be maintained at all times.
