Our design engineering know-how is spread across various business areas of our operations. All such offices are equipped with the latest hardware and software (including PDS) which is compatible with the systems being used by our clients. The IT-enabled network facilitates the exchange data with our clients in real time to track the progression of the design phase. This starts with basic design and extends to the detailed engineering phase.
There are three distinct groups for engineering and the total number exceeds 600 design engineers:
• Plant design
• Product design
• Infrastructure design
Plant design
Our plant engineering capability resides in Descon Integrated Projects Ltd. (DIPL) previously known as JGC-Descon. It is a full-fledged office with a capacity of one million man-hours per year. It can undertake the design of:
• Refining units
• Gas processing plants
• Chemical plants
• Fertilizer complexes
• CO2 recovery units
• Off-sites & utilities
• Tank farms
• Power plants

• Pressure Vessels
• Stacks
• Columns
• Skids
• Steel Structure
Infrastructure design
The Infrastructure Projects division has its own group of design engineers to support EPC contracts for dams/storage reservoirs, irrigation channels, barrages and hydro-electric projects.
The design capabilities cover:
• Surveyors and fully equipped designers and draughtsman.
• Hydraulic and hydrological Engineers.
• Geotechnical Engineer for Dams, Foundations, Structural Engineers, for bridges, aqueducts, etc.
• Road designers
• Geologists
• Instrumentation Engineers
• Mechanical Engineers for design fabrication and erection of steel structures.
• Electrical Engineers for design and detailing of hydropower projects.
