Over the past twenty years, ZHEC carried out countless dredging projects. In each project, the company achieved outstanding quality, which successfully satisfied the requirements of its customers. In recent years, the company has also won Hong Kong SAR Government dredging contracts, such as the Maintenance Dredging of Harbour Channels and the Penny's Bay Phase I Reclamation Project for the Disney Theme Park as well as the Kwai Chung Container Port Terminal 8 Maintenance Dredging Project.

Approximately 35 million cubic metres of sand fill (accounting for about 60% of the total amount of sand to be used for the reclamation) for the Phase I Reclamation Project was supplied by CHEC to Hong Kong from Mainland waters - a clear demonstration of ZHEC's leading position in dredging projects.
