KCC provides post-dredge inspection services to confirm that dredging has been completed to the specified formation level and to inspect adjacent structures for any dredging-induced movement, scour, or damage. Commercial divers systematically inspect the dredged formation, measuring levels at agreed grid points and recording any areas of over-dredge or residual high spots.
Adjacent structures — seawalls, jetty piles, pipeline crossings, and cable routes — are inspected for settlement, cracking, undermining, and scour. Findings are compiled into a post-dredge inspection report with diver photographs and level measurements, providing the client and engineer with the evidence needed to certify the dredge and identify any remedial works required.
Compliance: Post-dredge inspections are conducted in accordance with CEDD dredging guidelines and IMCA D 045. All diving operations comply with HSE Diving at Work Regulations 1997.
Dredging to the wrong level — whether under or over — has significant cost and programme consequences. A systematic post-dredge diver inspection provides the client and engineer with independent confirmation of formation level and early warning of any structural effects before they become serious.
Pre-Dredge Obstruction Survey
Pre-dredge diver survey to identify and record seabed obstructions, utilities, and unexploded ordnance indicators before dredging plant is mobilised.
Underwater Obstruction Clearance
Diver-based removal of concrete debris, old piles, cables, and other seabed obstructions to clear the dredge path before or during dredging operations.
