Concrete Slab Site Drawings

I need to hand my engineer a clean, scale drawing of the concrete slabs that support my backyard shed and the adjoining carport so he can complete the zone-of-influence calculations. I already have measurements of both slabs, including distances to the house, fence lines and other boundaries, so you will be working from solid field data rather than guessing.

What I require from you:

• A plan-view drawing for each slab that clearly shows overall length, width and position, plus the surrounding buildings and property boundaries noted in my measurements.
• North arrow, basic legend and clear dimensions so the engineer can lift figures straight from the sheet.
• Delivery in both PDF (ready for the engineer) and an editable CAD format such as DWG for my files.

No reinforcement, drainage or construction details are needed—just accurate geometry and context.

As timing is critical, a first draft within two days would be ideal, with final files wrapped up shortly after any minor tweaks. Tell me which CAD software you prefer and whether there’s any additional information you’ll need beyond the photos and measurement list I’ll supply immediately after kickoff.
