We have been engaged by Green Valley Landfill Limited as the Civil and Structural Consultant for the SENTX Hydrogen Demonstration Project. The project involves the construction of treatment plants for hydrogen synthesis, compression, storage, and refueling at the SENTX landfill site in Tseung Kwan O. The major design works include the design of steel structures and foundations supporting the equipment, r.c. firewalls, underground trenches for cables and drainage pipes, and roadworks.
