3D Sewer Manholes for TBC

Civil 3D + Trimble Business Center: 3D Sewer Manhole Models (53 Structures) I need a Civil 3D specialist to model 53 sewer manholes in 3D and compile them into one Trimble Business Center project for machine control. Quick turnaround needed. What I'll provide: - 2D site layout DWG with manhole locations and pipe runs - Control points (Texas State Plane North, NAD83, US survey feet) - Sewer plan and profile sheets with rims and inverts - Precast manhole fabrication drawings (base and cone are standard) What I need: - Build the precast base and cone once as a reusable template - Model each manhole with the chamber, all pipe connections and correct inverts - One DWG per manhole (53 total) with clear layer names - DWGs must open and stay editable in Civil 3D 2023 - One consolidated TBC project (.vce), ready for upload to Trimble Connect - A summary sheet (Excel) with structure names, coordinates, rims and inverts - Geometry must match the control points within 5 mm Requirements: - Licensed Civil 3D and Trimble Business Center (commercial, not student version) - Experience with pipe networks and TBC for machine control - Trimble Connect account to test the upload How we'll work: - Start with a test of 2 manholes, through to the .vce, before the full set - Project files shared after hiring In your proposal, please tell me: - Which Civil 3D and TBC versions/edition you have - A similar utility or machine control project you've done
