CTT provided complete engineering design services to produce contract documents for maintenance dredging of the Town’s “natural” canals, entrance canals, header and commercial canals. This project consisted of approximately 16,720 lf of dredging to -6.0 MLW of the "natural" canals, entrance canals and collector canals, which yielded approximately 73,000 cy of spoil material. Arnold Carson Surveying provided all bathymetry and topographic surveys for the ‘01 dredging while Gahagan & Bryant Associates, Inc. provided bathymetry and topographic information so that dredge quantities could be estimated for ‘05. Design services included analysis and quantity computations of spoil volumes, engineering design, cost estimates for maintenance dredging, survey mapping of canal dredge widths, preparation of technical specifications and contract documents, and meetings with the Town Commissioners.

 

Full bid and construction phase services were also provided by bidding project, receiving and recommending contract award to the Town, overseeing project progress and disposal of spoil material into an adjacent spoil basin along the AIWW, which included extending the containment dikes up to the appropriate level and periodic meetings with the Town and Contractor.

Other coastal engineering services included preparation of CAMA and USACE permits and environmental documentation required for this dredging project.
