Wiggins Pass and Doctors Pass Maintenance Dredging - Grant Funded

The Wiggins Pass Maintenance Dredge Project is located near the inlet portion of the main channel for Wiggins Pass in Collier County, Florida. The Contract Drawings were developed based on a survey from 01/2026 and show dredging of a total of approximately 81,000 CY of sand from the Wiggins Pass channels. This includes approximately 76,400 from a portion of the authorized main channel template from Station 11+00 east to Station C-12, approximately 1,500 CY from east Technical Specifications Page 4 of 42 channel located from station C-20 east to C-23, and another approximately 3,100 CY from the south channel ranging from the main channel south to Station C-32, and placement of the sand on the beach and in the nearshore south of Wiggins Pass along Delnor-Wiggins State Park from DEP reference monument R-18 to R-20. The main channel includes a relatively small area to avoid dredging along Stations 2+00 to -1+00 within the north side slope of the channel due to rock being encountered in this area in the past. The final determination of the quantity of sand to be dredged and/or placed on the beach will be based on the Contract Drawings dated 04/20/2026 which will be updated with the new pre-construction survey to be provided by the CONTRACTOR within two weeks from the commencement date stipulated in the written Notice to Proceed from the COUNTY. The Bid Schedule for this Work references an estimated quantity of 85,000 CY which is a higher quantity of dredging to account for potential shoaling and increase in the dredge quantity if documented by an updated acceptable survey conducted by the CONTRACTORs registered professional surveying subcontractor. TS-2.2 The Work must be completed according to the Contract Drawings and these Technical Specifications within the time specified in these specifications and contract and in compliance with the conditions of all federal, state, and local permits, including permits from Collier County, DEP, USACE, and USCG.
