1. Pipe works for water supply, sewage and drainage schemes  using DI, GRP, vitrified clay , SS, HDPE, PE, CPE, CPP, uPVC pipes, etc. Completed pipe line systems were comprehensive, varying in type from pressure to non-pressure, pipe sizes from 90mm to 2000mm diameter. Contract responsibility included investigations, designs, civil and building construction as well as mechanical & electrical installations including instrumentation and SCADA system. Typical projects were large and medium-sized water supply schemes for cities requiring construction of river intakes, dams, water and wastewater treatment plants, pumping stations, large capacity ground and elevated water reservoirs including post- tensioning,  transmission and distribution pipe lines requiring long river and lagoon crossings with undersea outfalls, etc.

2. Civil engineering construction including all kind of concrete works for special structures, high buildings, towers, bridges, tanks, dams, piling, underground structures, underwater structures, etc. Utilizing advanced technology and equipment CGC are able to undertake all aspects of designs and construction work.

3. Irrigation and conservancy including investigation, design, construction of bridge, culvert, dam, tunnel, underwater structure, explosion, etc.

4. Hydropower and wind power generation including geological survey, design and construction with Mechanical & Electrical installation.

5. Waste water, waste gas, solid waste management region which under CECEP’s cooperation, CGC are able to implement waste treatment system by advanced technology.

6. Geological survey and mineral geological survey

7. Geological hazard mitigation including foundation improvement, slope stabilization, etc.
