Hydropower CAD Conceptual Modeling

Need complete conceptual-level CAD support for a new hydropower scheme. The work centers on three structure types—dams, powerhouses, and the intake / outlet works—so each of these must be represented in 3-D with the accuracy expected at feasibility stage. I use AutoCAD Civil 3D in-house, therefore the source files must remain fully compatible with that platform; IFC or STEP exports are a plus but not essential.

Alongside the models I also need:

• Preliminary quantity take-offs generated directly from the Civil 3D objects (concrete volumes, earthworks, key reinforcement weight estimates).
• Basic geological drafting: clean DWG cross-sections and plans that overlay bore-hole data and regional mapping I will supply.

Acceptance criteria
– Geometry reflects the layout sketches and reference elevations I will share; ±10 % tolerance on volumes is acceptable at this stage.
– Layer naming and object styles follow my Civil 3D template (I will provide).
– All files delivered in DWG; PDF plots for quick review.

Please indicate how long you need to turn around the first iteration once you receive my base survey and outline alignment.
