How a set comes together

From an address to a set ready for your engineer's seal

Sample site plan for a DC fast-charging plaza A site plan that builds in five layers: the site, the equipment, the conduit routes and single-line diagram, the title block, and the engineer's markup and seal.

Sample sheet, for illustration
01  SITE

It starts with your site.

Send the address, the utility and what you plan to build. We draw what's there first: the property line, the building, parking and access.

02  EQUIPMENT

Then the equipment.

Chargers, transformer and switchgear go where you and your engineer decide they belong, with the stalls, pads and bollards around them.

03  CONNECTIONS

Then how it all connects.

Trench routes run from the utility to the equipment pad to every dispenser, tied to a single-line diagram on its own sheet.

04  THE SET

Every sheet titled, numbered and indexed.

Each sheet carries a title block, a sheet number and a revision table, and matches the index, so a reviewer can find what they need.

05  YOUR ENGINEER

Your engineer has the last word.

They mark up the set. We cloud every change and log it in the revision table. When every sheet is right, they seal it and you submit.

Your engineer makes the engineering calls. We put every one of them on paper, on every sheet, and keep a record of every change.

Services

What we draft

For contractors, developers and site owners who have a project and need the drawings to move it forward.

I need to

Permit plan sets

The full drawing set for the building department: site plan, layouts, single-line diagram, elevations, details and labels. Drafted to your engineer's criteria and revised to their markups until it's ready for their seal.

For the building permit

Application drawings

The drawings a grant, rebate or incentive program asks for, matched line by line to the program's own checklist.

For the funding application

Utility service requests

The site plan, single-line diagram and load summary your utility needs before it will size a new or larger service.

For the power company

Plan-check revisions

When the reviewer's comments come back, we update the sheets, cloud every change and log it in the revision block, so the resubmittal answers each comment by number.

    Process

    How a job runs

    Send the project

    Send the site and the equipment, and tell us who your engineer is, or ask us to introduce one. We reply with a fixed price and a delivery date in writing.

    We draft

    Your engineer sets the criteria. We draw the sheets to them and keep a decision log, so every call on the drawings traces back to the person licensed to make it.

    Your engineer marks up

    We turn the markups and reissue the set until your engineer is satisfied with every sheet.

    Seal and submit

    Your engineer seals the set and you submit it. If plan check sends comments, we handle the revisions.

    • Keeps titles, numbering and notes consistent across the set
    • Tracks revisions and the decision log

    We draw. We don't play engineer.

    Draft Horse is a drafting company. We don't practice engineering and we don't promise permits; approval is the building department's decision. Our job is to hand it a clear, complete set, and to turn every markup that comes back.

    Permit sent back with comments? Send us the comment letter and the current set. We'll tell you, free, which sheets change and what it costs to answer every comment.

    Questions

    Common questions

    Are you an engineering firm?

    No. Draft Horse is a drafting company. A licensed engineer directs the work on every permit set and is the one who seals it.

    Do I need my own engineer?

    No. If you have one, we draft for them. If you don't, we'll introduce you to an independent licensed engineer we work with. You hire them directly, and they direct the work and seal it. Either way, the engineer is on the job before we start drawing.

    Will my permit be approved?

    That's the building department's decision, so nobody can promise it. We draw a clear, complete set and stay on the job through plan-check comments.

    Is the readiness check really free?

    Yes. Send what you have and we'll reply with the sheets your job needs, what's missing and a fixed quote. There's no obligation to go ahead.

    What do you need from me?

    Whatever you have: the site address, the utility, an equipment list or cut sheets, existing drawings or photos, and your engineer's contact. The free check tells you what's missing.

    What do I get back?

    A PDF plan set on titled, numbered sheets, with a revision block that shows what changed and when.

    Do you do residential?

    Yes. Rooftop systems up to 15 kW with standard equipment start at $79, delivered the next business day once we have everything we need. Larger systems are quoted per job.

    Where do you work?

    We're based in Idaho. Whether we can take a job elsewhere depends on that state's rules and where your engineer is licensed, so ask.
