Frequently Asked Questions

What does CIDA Grade C-7 in Water Supply signify?

Grade C-7 is the highest possible registration grade awarded by the Construction Industry Development Authority for water supply and sewerage projects in Sri Lanka, meaning there is no financial limit on the projects we can undertake.

Do you provide mechanical and electrical (M&E) installation for treatment plants?

Our core expertise lies in the extensive civil and structural engineering requirements of treatment plants. We typically collaborate with specialized M&E contractors or act as the main contractor managing M&E subcontractors.

What types of irrigation projects do you handle?

With our CIDA C-1 grading, we construct major irrigation canals, structures such as anicuts and spillways, and undertake rehabilitation of tanks and reservoirs for agricultural zones.
