Detailed Engineering Design (DED) & Bill of Quantity (BoQ)

The detailed engineering design is the construction blueprint: designs precise enough that a contractor can price, build and be inspected against them, with no redesign left for the construction site.

Every structure is designed hydraulically and structurally — the weir, side or Tyrolean intake, desander, headrace, forebay with spillway, penstock (diameter traded off against friction loss, wall thickness checked for working pressure plus water-hammer surge), powerhouse and tailrace — together with the turbine, generator, control and protection specification. The Bill of Quantity then translates the drawings into itemised, measured work: excavation and concrete in cubic metres, reinforcement in kilograms, penstock pipe by the metre and diameter, equipment by unit or lot. Because every bidder prices the same quantities, bids are comparable and progress payments can be certified against the BoQ.

• Hydraulic and structural design of weir, intake, desander, headrace, forebay, penstock, powerhouse and tailrace
• Turbine, generator, control, protection and line specification
• Full construction drawing set and technical specifications
• Itemised BoQ with measured quantities and an engineer’s cost estimate
• Tender-ready documents

What you receive: the DED report and calculations, the construction drawing set, technical specifications, the BoQ with the engineer's cost estimate, and tender documents where required.
