What our site utility plans include
Utility plans have to fit many pipes and cables into limited space without conflicts, at the depths and separations the authorities require. Water and sewer lines need horizontal and vertical separation; gravity sewers need minimum slopes; fire lines need hydrant coverage; dry utilities need their own corridors.
We model utilities as Civil 3D pipe networks (and pressure networks for water) so profiles, crossings and depths are checked automatically. Conflicts are shown at every crossing with clearances, and connection details follow the utility owner's standard drawings.
Utility design works hand in hand with grading and drainage plans. Building-side plumbing is covered by plumbing design and riser diagrams.

Site Utility Plans standards in the USA, UK, Canada and Australia
We set up every project on the standard of the country where it will be built or manufactured. These are the references we work to most often:
| Country | Standards and codes we draft site utility plans to |
|---|---|
| USA | Recommended Standards for Water Works / Wastewater Facilities (Ten States Standards) where adopted, AWWA standards, local utility standards, NFPA 24 for private fire mains |
| UK | Water UK Design and Construction Guidance (sewers for adoption), NJUG guidelines on positioning of utilities, water company standards |
| Canada | Municipal design standards, provincial guidelines (e.g. MECP Design Guidelines for sewage works), NFPA 24 as adopted |
| Australia | WSAA Water Supply and Sewerage Codes, local water authority standards, AS/NZS 3500 for property services |
Engineering responsibility: we prepare drawings, models and calculations as a drafting and design-support team. Where the law in your state, province or council requires it, the final design must be reviewed, signed and sealed by the licensed engineer or architect of record for the project. We work to their markups and do not stamp drawings ourselves.
How our site utility plans process works
- 1Send your files
Upload sketches, PDFs, markups, photos, scans or a model through the quote form. Tell us the standard (US, UK, Canada or Australia) and the deadline.
- 2Fixed quote in hours
We review the scope and reply with a fixed price, the deliverables list and a delivery date. Nothing starts until you approve it.
- 3Drafting & modeling
Your project is drawn in AutoCAD, Revit, Civil 3D, SolidWorks or the software you use, on your title block, layers and templates.
- 4QA check
A second drafter checks dimensions, annotations, layer standards, sheet numbering and cross-references against your input before anything is sent.
- 5Delivery & revisions
You receive native files plus PDFs. Comments come back as markups and we revise them quickly until the set matches the brief.
Turnaround and pricing
Utility plans for a small commercial site are typically prepared in 4–7 business days. Every job is priced as a fixed quote after we review your files, so you know the cost and the delivery date before work starts. See how our pricing works, or send your files through the quote form for a quick estimate.
