Mandalay Canal Maintenance Dredging
This project involved the planning, design and permitting for the maintenance dredging of a power plant cooling water canal. Work involved hydrographic surveying, channel design, chemical analysis of sediments, preparation of permits and regulatory documents, evaluation of alternative upland dredged disposal sites, and preparation of plans and specifications for construction bidding. Noble Consultants, Inc. completed a pre- and post- dredge survey of the 11,000-foot long cooling water intake canal for the Mandalay Generating Station. The survey consisted of transverse sections across the canal at approximately 40-foot intervals along the entire length of the canal. The sections were acquired using our Trainable Acoustic Beam Sea Floor Profiler mounted on one of our survey vessels. On several occasions NCI surveyors assisted the dredge contractor in determining placement of his equipment along the winding canal. NCI surveyors conducted several interim surveys during dredging to determine compliance with the dredge plan. The data were processed and mapped using MicroStation software. Dredgeable material quantities were calculated, and electronic files of the maps were provided to the client.
