The task is to generate complete plan layouts and elevation drawings for a new Bio-CNG production facility. I already have the process flow; what is missing are construction-ready drawings that clearly show how the core areas fit together—specifically the storage tanks, digesters and downstream processing units. The expectation is a detailed design with full specifications. Dimensions, equipment footprints, clearances, pipe racks, utility corridors, and structural references all need to be called out so that civil, mechanical and electrical teams can build directly from your files. AutoCAD (or compatible DWG) will work best for 2-D sheets, but a 3-D model in Plant 3D, Revit or similar is welcome if it helps illustrate spatial clashes. Deliverables • General arrangement plan showing overall plant plot • Separate floor plans for each production zone • Elevation and section views for storage tanks, digesters and processing units • Equipment list keyed to drawing codes • PDF set for quick review plus editable CAD source files Acceptance criteria Drawings must align with the provided process flow, respect minimum safety distances for Bio-CNG operations, and be ready for a professional engineer’s stamp without redrafting. I will review in two rounds: first for layout logic, second for dimensional accuracy and annotation clarity.
