River Earthwork Quantity Extraction -- 2

I already have complete survey data for a 50 km river stretch along with the approved design section. All I need now is a precise earthwork quantity take-off—soil only—in cubic meters. What I will hand over to you • Raw survey levels (CSV + DWG) • Design longitudinal profile and typical cross-sections • Reference chainage plan What I expect back • An itemized volume statement in cubic meters for each chainage interval, clearly separating cut and fill where relevant • Supporting cross-section or volumetric graphs generated in AutoCAD Civil 3D, MX Road, or any equivalent professional tool so I can visually verify the calculations • A brief note on the calculation method (average end-area, prismodial, or whichever technique you use) Accuracy is critical because this sheet will feed directly into the tender. If you are a civil engineer who routinely works with river training or irrigation projects and can turn my data into a clear, audit-ready quantity sheet, let’s move forward.
