WHEN A DRAWING FEE APPLIES AND WHAT IT COVERS

Shop Drawing Fees and Design Assist Before Fabrication

Whether You Pay for a Drawing Depends on What You Send

You pay a drawing fee when you send a sketch or photos instead of drawings with every size marked.

A shop drawing fee covers the time it takes to draw your part to scale before it can be priced and built. A shop drawing is what a fabricator builds from, with each size, bend, seam, and connection marked. At Duct Duct Goose, the fee comes off your order if you place one. This guide covers when you'll need one and what the fee includes. It also explains design assist, and who owns a drawing once it's paid for.

Will Your Request Need a Drawing Before It Can Be Priced?

The files and sizes you have decide whether we draw your part before pricing it. Find your situation below.

What you haveDo we draw it first?What happens next
A PDF with every size markedNoWe price the part straight from your PDF
A DWG or DXF fileNoWe price from the file, and it goes straight into the software that programs our machines
A standard duct fittingNoYou price and order it on WebDuct, with a company account
A hand sketch with sizesYesWe draw it to scale, and the fee applies
Photos with a tape measure in the frameYesWe ask about any size we can't read, then draw it
A part that has to fit equipment not chosen yetNot until the equipment is chosenWe need its model number and sizes first
A part that needs an engineer's sealYes, after your engineer designs itYour engineer designs it, then we make our drawing from their design

Why photos are different from fabrication drawings covers what a photo can't show. Adding those details to your photos cuts down the questions before we draw.

What a Shop Drawing Fee Pays For

The fee covers the drafting, the questions about missing sizes, and the details a sketch leaves out. It also gets you a drawing to check before any metal is cut.

If you send a sketch or photos, someone has to draw each size, bend, and seam to scale. That time is most of what the fee covers.

If a size can't be read from what you sent, we ask before drawing it. A guess drawn neatly to scale is still a guess.

If the sketch doesn't say the gauge, the seams, or how the part connects to the duct, our drawing has to. So we ask you before it's drawn.

If our drawing shows something you didn't mean, you catch it before any metal is cut. What you approve is what we build.

What Happens to the Drawing Fee if You Order, and if You Don't

Credited means the fee comes off the price of your order. Whether that happens depends on what you decide once the drawing is done.

If you place the order

The fee is credited, so you don't pay twice for the same drafting. The drawing you approved is the one the part is built to.

If you don't place the order

The fee isn't credited because it was paid for drafting already done. Before drafting starts, ask what you'll receive if you don't order.

Who Is Responsible for Each Kind of Design Work on a Part

Four kinds of design work can sit behind one part, and each makes a different person responsible. Knowing which one you need tells you who to ask first.

Kind of workWhat it isWho is responsible for the designCommonly used for
Shop drawingA drawing of how the part is built, with sizes, metal, gauge, seams, and connectionsThe contractor who submits it, even after the engineer reviews itDuct fittings, transitions, curbs, drain pans, and stainless counters
Design assistA trade advises the engineer on how something can be built while the design is still being drawnThe engineer of record, who keeps the designLarger or unusual systems, where the way it's built changes the design
Delegated designThe engineer hands the design of one part to a trade's own engineer, who seals the drawings for itThe trade's engineer, for that one partSprinkler systems, stairs, and railings, and seldom sheet metal
The engineer's drawingsThe sealed design the engineer or architect issues for the projectThe engineer or architect who seals themHVAC layouts, fire dampers, and duct openings through fire-rated walls

Canada's National Master Specification says the engineer's review only checks a shop drawing against the design. The contractor who submits it stays responsible for its details, even when a fabricator drew it. Our drawings show how to build a part, and anything that needs an engineer's seal comes from the project's engineer.

What Design Assist Means on a Sheet Metal Job

Engineers and contractors use design assist to mean one kind of help, given before the design is finished. The term comes up most on larger or unusual commercial projects.

On a sheet metal job, a fabricator's part in design assist is usually checking that a design can be built. It also means saying what would make the part simpler to make.

A check that the part can be built as designed

If a part can't be bent or joined the way it's designed, we say so early. The engineer can change it before anyone pays to have it drawn.

A simpler way to build the same part

If a fold can replace a weld, or a standard size can replace an odd one, we'll suggest it. The part does the same job and costs you less.

Help laying out an exhaust system

If you need equipment exhaust ducting or fume extraction, we can help lay out the system, then supply and install it. Anything that needs a seal still goes to your engineer.

Sealed drawings come from your engineer

If a part needs a sealed drawing, the project's engineer provides it. We don't do engineering or seal drawings.

What a Drawing Costs to Produce

Most of what a drawing costs is drafting time. The Government of Canada's Job Bank publishes drafting wages by region. In the Lower Mainland, the median wage for a drafting technician is $32.21 an hour, ranging from $20.00 to $52.88.

Example in Canadian dollars, hours assumed, not a Duct Duct Goose quoteOne fitting from a sketchTwelve fittings from photos
What arrivesA hand sketch with every size markedPhotos with a tape measure in most of them
Drafting time, hours15
Time on questions about missing sizes, hours01
Wage cost at the $32.21 median, not a Duct Duct Goose quote$32.21$193.26

The hours are assumed, and the figures are wages, not a billed rate. A billed rate also covers software, the office, and overhead, so a drawing fee is higher than the wage alone. Sizes that arrive complete take the question time out, which is the part of the cost you control.

Who Owns a Drawing You Paid For

Under Canada's Copyright Act, who owns a drawing depends on who drew it, not who paid for it. Three things follow from that.

Whoever draws it, or their employer, owns it

The person who draws a drawing is its first owner. If an employee draws it as part of the job, the employer owns it.

Paying for it doesn't transfer ownership

Ownership moves only through a written assignment signed by the owner. Paying usually permits you to use the drawing on that job.

Ask in writing before you reuse it

If you plan to take a drawing to another fabricator or use it on a later job, ask whoever drew it. Get their permission in writing.

Common Mistakes That Add Drafting Time to a Request

Most drafting charges, and most drawings made twice, come from something missing in the first message. Each fix below saves time at the drafting table.

What happenedWhy it adds drafting timeWhat to do instead
Photos sent with no tape measure in themNo size can be read, so every one has to be asked forHold a tape measure across each opening in every photo
A scanned drawing with no sizes on itIt shows the shape but not the size, so the part is drawn againSend the dimensioned PDF or the DWG file
Sizes changed after our drawing was madeThe drawing is redone with the new sizesMeasure and confirm on site before asking us to draw it
A sealed part sent to us before the engineer's designAnything drawn before the design is final has to be redoneGet the engineer's design first, then send it to us
A drawing approved without checking the sizesA change after approval means redrawing, and sometimes remaking the partCheck sizes, quantities, metal, and openings before you sign

How to measure ductwork for a custom fitting shows how to take sizes we can work from. What happens after you approve the drawings covers what a change costs once they're signed.

How Duct Duct Goose Handles a Request That Needs a Drawing

A request we have to draw first runs through five steps. They're the same for one fitting or a full package.

  1. Send what you have. PDF drawings, DWG or DXF files, photos with tape measurements, and hand sketches all work.

  2. We say what's missing. We list any size, metal, or detail we still need, and whether the part has to be drawn.

  3. We draw the part. The fee applies, and it's credited when you place the order.

  4. You check and approve it. You check the sizes, quantities, metal, finish, and openings, and your approval is what we build to.

  5. We turn it into cutting files. The approved drawing becomes the flat patterns and programs our machines cut from.

The part then runs through our cutting and bending work, whether it's for custom duct fittings or a one-off bracket. The sheet metal fabrication capabilities page lists what we can make from it.

When Paying for a Drawing Makes Sense, and When It Doesn't

The fee is worth paying when no usable drawing exists. When one already does, there's nothing left to draw.

Worth paying for

  • A worn-out part you want copied
  • A retrofit where the old drawings are lost
  • A fitting that joins two odd sizes on site
  • A part you'll order again and want drawn once

Not needed

  • Engineer's drawings that already size every part
  • A dimensioned PDF or DWG file
  • A standard fitting you can price on WebDuct
  • Budget pricing for a job that may not go ahead

If your drawings already show every size, send them as they are. We'd rather price from what you have than charge you to draw it again.

What to Send So Your Part Is Quick to Draw and Price

Each item on this list is one less question before drafting starts. With all of them, a sketch can be drawn in one pass.

Before drafting starts, also tell us who will approve our drawing on your side. Then ask what you'll receive if you don't place the order. What Duct Duct Goose needs to quote custom metalwork has the full list for a quote request. More cost guides sit in Custom Fabrication Cost Guides.

Send What You Have, Drawn or Sketched

Clean drawings or a rough sketch with sizes are both a starting point. Send them over, and we'll tell you what's missing and whether the part has to be drawn first.
