3D CAD Water Infrastructure

I need complete 2-D and 3-D civil-engineering CAD drawings for an infrastructure project centred on a commercial drinking-water system that will serve a new bus-stand complex. The scope runs from overall site layout right down to the details of the water-treatment facility itself, so plan, profile, section, and presentation views are all required.

Here is what I expect:

• Accurate civil CAD files (.dwg) showing the full layout of the treatment plant, inlet and outlet lines, building footprints, and any structural or architectural elements that tie the system to the bus-stand.
• A coordinated 3-D model (AutoCAD, Civil 3D, or compatible) that illustrates pipe runs, equipment positions, and clearances, suitable for clash detection and quantity take-offs.
• PDF plots ready for permitting and stakeholder review.

Please keep layer standards clear, use metric units, and maintain real-world coordinates so the drawings can drop straight into our master site model. If you have previous experience on municipal or commercial water projects, let me see a sample—technical accuracy and constructability are my prime concerns.
