3D Piping Drafter — Small Bulk Fuel Plant Plant 3D Back-and-forth with Principal | Redline & Iterate Anyone

We are a small Florida/Texas engineering firm looking for an experienced piping drafter to build and maintain 3D piping models and drawing packages for small bulk fuel plants (not mega-terminals). Work is remote. You will work directly with the Principal Engineer — not through layers of project managers.
What this is
Typical sites: small bulk plants, cardlock / wholesale fuel, modest tank farms, loading racks, pump pads, and manifold style work. Emphasis on small-diameter process and product piping (generally ½"–6", occasional larger headers), tight equipment spacing, and constructible routing — not long-distance pipeline or refinery-scale racks.
You will take, plot plans, equipment data, and markups and produce a clean, intelligent 3D model plus extractable drawings. The Principal will redline in PDF/CAD, we will talk through conflicts, and you will iterate until the package is ready to issue.
This is a working relationship, not a one-shot gig. If the first package goes well, there is ongoing work.
Software (must have one; both is better)
• AutoCAD Plant 3D or we can discuss others.
• AutoCAD 2D for cleanup / details
• Ability to extract isometrics with BOM and a simple MTO
Tell us which platform you live in. We will match the model to what we can maintain in-house.
Deliverables (typical package)
• Intelligent 3D piping model
• Piping plans / sections / GAs
• Isometrics with BOM
• Bonus points if you can take some of the ones we have done in the past and match them in cad for permitting.
Start small: one system or one area, then expand.
How we will work
• Principal issues P&IDs, plot, photos, and a short written scope
• You model a first pass
• Principal redlines (routing, fittings, supports, clearances, constructability)
• Short call or markup review as needed
• You revise and re-issue
• Repeat until it is clean enough to stamp/issue
You must be comfortable with iteration. First-pass “done” that ignores redlines will not work. Clear English, same-day or next-day replies during US Eastern business hours preferred.
What good looks like
• You have done tank farm / bulk plant / loading rack / small process plant piping, not only HVAC or architectural CAD
• You understand small-bore routing: valves accessible, no buried flanges in the dirt, supports that a fabricator can actually build
• You can work from incomplete field info and flag gaps instead of inventing pipe
• Portfolio includes extracted isos with BOM, not only rendered pictures
To apply, send
1. Software you will use and version
2. 2–3 samples: bulk plant, tank farm, rack, or small process piping (iso + plan or model view)
3. Hourly rate and a ballpark for a small first package (e.g. one product system + pump pad, ~X isos)
4. Typical turnaround for a first-pass model after receiving P&IDs
5. Time zone and hours of overlap with US Eastern
Do not send a generic “I can do any 3D piping” message with no samples.
Start
Paid test / first package: one small area (pump pad + short one product loading line). If that iterates cleanly, we keep going. read less
