Checking your own set — Drafting Millwork

Checking a drawing is a different job from drawing it, and it wants a different order. When you draw, you move from plan to detail. When you check, work from the outside in: the set as an object first, then the numbers, then what the numbers describe, then how it meets everything around it. The last pass is not yours at all. It belongs to someone who builds from drawings.

This chapter is a checklist. It is built from two real drawing sets, the Woodwork Institute's published sample, the public pages of the woodwork standards, the 2010 ADA Standards, and the checklists that drafting firms publish. Where a source is a firm selling drafting, the page says so. Print the lists, adapt them to your shop, and tick them off on paper. A checklist you only read in your head is a checklist you skip.

Before you start: have the right documents open

The architect's current drawings, with every addendum and bulletin.
The specification sections for woodwork, and any others your work touches (finishes, doors, plumbing fixtures, electrical).
The standard the spec names, in the edition that applied at bid (Chapter 19).
Your RFI log, with every answer (Chapter 24).
The last reviewer mark-up, if this is a resubmission.
The hardware cut sheets.

You are checking against these, not against your memory of them.

Pass 1: the set as an object

Flip through the whole set without reading a single dimension. You are checking that it is complete, in order, and navigable.

Sheet size. The Woodwork Institute's sample states: "MINIMUM SHEET SIZE REQUIRED BY W.I. IS 11" x 17"." Check the size your standard or client requires, and check that the set prints legibly at it.
Sheet numbers read n OF n. The residential submittal in hand prints 04 OF 16. A loose sheet on a bench then tells you what is missing.
A sheet index on the cover, listing every sheet with its number, title and current revision. The LinkedIn submittal checklist by Anuj S.: "Include drawing names, numbers, revision numbers, and dates".
The order zooms in. Cover, plans, elevations, enlarged items, sections, details (Chapter 5). The residential set runs plans and elevations at 1/2"=1'-0", one enlarged item at 3/4"=1'-0", then sections and details at 1" and 1 1/2"=1'-0".
Scale printed under every view, not only in the title block. A sheet with mixed scales needs each one labelled.
Required views present. The Woodwork Institute sample's floor plan sheet lists what a shop drawing must include: "1. FLOOR PLAN 2. CABINET LOCATION 3. CABINET ELEVATION & SECTIONS 4. CABINET JOINERY DETAILS 5. ROOM & BUILDING LOCATION (OPTIONAL)".
Title block complete on every sheet. The Woodwork Institute sample's fields: company, address, phone and fax, state licence number, job name, job address, construction manager, architect, sheet number, job number, scale, date, drawn by, reviewed by.
Revision block current on every sheet. Every issue has a row. Every row says what changed, why and where (Chapter 24).
Status on every sheet. For approval, for construction, or whatever your office uses. The residential set prints SUBMIT FOR APPROVAL.
General notes on every sheet, not only the cover. Sheets get separated. The residential set repeats "FINISHES TO BE REVIEWED AND APPROVED BEFORE FABRICATION" on all 16 sheets.

Callouts, both directions

This check takes the least skill, which is why it gets skipped. Make two lists.

Every callout bubble on every sheet: the letter or number, and the sheet it points to.
Every detail and section actually drawn: its letter or number, and the sheet it sits on.

Every item in list 1 must appear in list 2. Every item in list 2 must appear in list 1. In the residential set, callouts A to P on four elevation sheets land on sheets 9 through 16. A callout pointing at a detail nobody drew is a question the floor will phone you about. A detail nobody calls is a detail nobody will find. Check the sheet numbers inside the bubbles too: a renumbered set breaks every callout that pointed at the old numbers.

Pass 2: the numbers

Every run closes. Add the parts, compare with the overall, on plan and on elevation. Horizontal and vertical.
Every overall matches the architect. Or the difference has an RFI number next to it.
Every vertical stack closes. Toe kick plus carcass plus top equals the stated counter height. Wall cabinet bottom plus height equals the stated top. Check against the ceiling height on the architect's sections and reflected ceiling plan.
Field dimensions marked. VIF where the number depends on site, and a note of who verifies and when. Dimensions already measured are marked as measured. QeCAD, a drafting services firm, cautions: "Avoid ambiguous notes like 'verify on site' unless absolutely necessary."
Scribes and fillers dimensioned. Shown on plan and elevation, with the allowance stated. Not left to site.
Tolerances stated where fit matters. Reveals, panel joints, flush details. Use the tolerance tables for the job's standard and grade (Chapter 20).
Clearances at full travel. Doors at full swing, drawers at full extension, appliance doors open. Check against adjacent walls, door frames, handles on the next unit, and inside corners.
Units consistent. QeCAD again: "Units (imperial or metric) should be consistently applied throughout the document". If the job mixes them, every dimension says which.
Part sizes against stock. Every panel fits the sheet goods you stock. Every solid part fits the lumber you can buy. A split or joint is drawn where a part is bigger than the material. Leo Christo's checklist for Enginerio, written for fabrication in general, asks: "Are part splits or joints included if the part exceeds material or equipment limits?"
Delivery and access. The largest assembled piece fits through the doors, stairs and lift on the way to its room. If it does not, the drawing shows where it breaks down.

Pass 3: what the numbers describe

Standard and grade

The cover states the standard by publisher, name and edition, and the bid date (Chapter 19).
The cover states the grade for each product type. The Woodwork Institute sample does this in a block headed W.I. SPECIFIED GRADE.
Grade boundaries are shown on plan where the grade changes.
Certification requirements are listed: labels, certificates, inspections.

Materials and surfaces

Every panel has a substrate and a thickness.
Every face has a finish: species, cut and match for veneer; manufacturer, colour and pattern for laminate; system and sheen for paint.
Every exposed edge has an edge treatment.
Exposed, semi-exposed and concealed surfaces are distinguished where it matters, and each surface's material matches what the grade requires (Chapter 20).
Grain direction and match are stated on elevations. Sequencing or blueprint matching between units is shown only if specified.
The Woodwork Institute sample uses a specification requirements sheet for this, with a block per product: case body, cabinet shelves, wall shelves, hardware, door and drawer fronts, countertops, drawer box. Each block lists core material, edgeband and thickness, exposed and semi-exposed faces. A form like that makes a missing entry visible.

Construction

Carcass construction shown in section, not implied by an elevation: frameless or face frame, back, bottom, top, stretchers, toe kick.
Joinery shown or named at every joint type. The Woodwork Institute sample gives several sheets to "TYPICAL JOINERY DETAILS".
Anything drawn as a reveal, shadow line or mitre has a dimension and a section behind it.
Shelf thickness and span checked. The Woodwork Institute sample's elevations carry the note "3/4" OR 1" SHELVES CHECK AWS FOR SPAN". AWS 2nd Edition, Section 10, sets a deflection limit: "L/144 (the length of the shelf divided by 144) is the industry standard for the maximum acceptable deflection of a shelf, which permits 1/4" (6.4 mm) deflection in a 36" (914 mm) shelf." Check the current text for your job.
What ships assembled and what is assembled on site is stated. Enginerio's checklist: "Is it clear what is shop-assembled versus field-assembled?"
Anchorage shown, and blocking assigned. The Woodwork Institute sample has a sheet of anchorage details, and a general note: "ALL BLOCKING FOR CABINET ANCHORAGE IS BY OTHERS."

Hardware

A hardware schedule: make, model, finish, quantity per unit, for every item. The Woodwork Institute sample lists finish, hinges, pulls, drawer slides, file drawer slides, shelf standards, shelf clips, catches, elbow catches, sliding bolt, door lock, drawer lock, keying and grommets, each with a product reference, "PER SCHEDULE" or N.I.C.
Every item on the schedule is located on the drawings, or the drawings say setting-out follows the manufacturer's instructions.
Handing shown on every door.
Every boring or machining dimension comes from the manufacturer's technical document, cited. Not from memory, not from the last job (Chapter 15).
A cut sheet for each item is in the submittal. The LinkedIn submittal checklist lists "Cut sheets for all hardware and integrated products".
No TBD left. Each one is an RFI.

Tops

Material, thickness, edge profile, overhangs, backsplash, cutouts, joints, support. The Woodwork Institute sample's countertop block: core material and thickness, laminate minimum thickness, post-forming thickness, backing sheet, type (coved splash), and "NO DRIP FRONT EDGE".
Cutouts located and dimensioned from the fixture's cut sheet. The sample notes "ALL SINK CUT-OUTS MUST BE SEALED."
Who supplies, templates and installs the top, if it is not you.

Pass 4: coordination

This pass is about everything that is not yours but touches yours. The mclinestudios checklist puts it plainly: "Identify potential conflicts or overlaps between your system and others." Check your set against:

The architect's plans and sections. Walls, columns, windows, door swings, floor finishes and their thicknesses.
The reflected ceiling plan. Ceiling heights, bulkheads, soffits, sprinkler heads, lights and diffusers over tall units. Ripudaman Singh's article for HitechDigital lists reflected ceiling plans among the drawings a millwork submittal includes, for "the relationship between millwork and ceiling elements like soffits, coves, or bulkheads".
Electrical. Outlets, switches and data inside or behind millwork. Lighting in millwork: fixture, driver, cable route, who supplies and connects.
Plumbing. Sinks, taps, waste and supply positions against cabinet backs, bottoms and drawers.
Appliances. Every appliance's cut sheet: opening size, ventilation, door swing, service access.
Other trades' finishes. Tile, stone, plasterboard, flooring: who stops where, and who installs first.
Ownership of every interface. Every item that is not yours says so. The Woodwork Institute sample's general notes do it item by item: "PLUMBING/FIXTURES BY OTHERS", "ELECTRICAL/FIXTURES BY OTHERS", "PAINTING/FINISHING BY OTHERS", "ALL RUBBER, VINYL, OR FINISH BASE TO BE SUPPLIED BY OTHERS".

Pass 5: code

If the job is covered by accessibility rules, check each accessible element against the governing code. For the US, Chapter 22 gives the 2010 ADA Standards sections. The short list:

Work surfaces 28"–34" A.F.F. where 902 applies.
Service counters: an accessible length at 36" max, at the full depth of the counter (904.4).
Sinks: rim or counter 34" max, knee and toe clearance, pipes protected (606).
Knee and toe clearance dimensioned in section (306), and alcove widths checked (305.7).
Accessible storage within reach ranges (308, 811), and its hardware operable per 309.4.
Wall-hung items in circulation paths protrude 4" max if their leading edge is between 27" and 80" A.F.F. (307.2).
Shim allowance stated where a height sits near a limit.
Any state or local addition the spec names, repeated on the cover.

Pass 6: the open items

Every open question is in the RFI log, and has been sent.
Every assumption on the drawings is labelled as an assumption, with its RFI number, next to what it governs and in the general notes.
Every answered RFI has reached every sheet it affects. Check the "sheets affected" column in the log against the drawings.
Every comment from the last review is incorporated, questioned or answered (Chapter 24).
Every change since the last issue is marked on the sheet and described in the revision block.
Nothing that is still an assumption is marked for release to the floor.

Pass 7: clarity

A set can be right and still unusable. Ripudaman Singh's HitechDigital article warns that "A detailing overload in millwork drawings however creates information clutter and difficulty for the shop floor to zone in on relevant information." The article suggests standard items such as "screw type, length, and size can be omitted". Ask of every note on the sheet: does the person reading this sheet decide something with it?

Text is readable at the printed size.
Line weights separate cut lines from lines beyond.
Abbreviations are standard or defined in a legend.
Notes sit next to what they govern.
Repeated information lives in one place, a schedule or the general notes, and is referenced, not copied onto every view.

Pass 8: the last pass

Someone who builds from drawings reads the set. A machinist, a bench hand, a lead installer. Not to approve it. To tell you what they would ask if it arrived on their bench.

If you want to know if your drawings are good, ask the people who have to build from them.
A commenter on r/Millwork

This pass differs from the other seven: it is the only one done by someone who does not share your assumptions. It is also the one people skip under deadline. Ten minutes at a bench before the set goes out costs less than one phone call from the floor after.

What to ask them:

Can you cut every part from what is on these sheets?
Is there any joint you would build differently from how it is drawn?
Is there anything you would have to ask me?
Is there anything on here you would ignore?

The last question finds clutter. The first three find holes.

Keep a record of the check

Initial the reviewed-by box in the title block when you have done the passes. The Woodwork Institute sample's title block has separate fields for "DRAWN BY" and "REVIEWED BY"; the residential set was drawn by one person and checked by another. If you are checking your own work because there is no one else, say so on your checklist, and let the shop-floor read in Pass 8 be your second pair of eyes.

Keep the marked-up checklist with the revision it checked. When a question comes back months later, you can show what was checked and when.

Why this order

The order matters because each pass depends on the one before. There is no point checking a dimension on a detail that is called from nowhere. There is no point checking a material callout against the grade until you have confirmed the grade. There is no point asking the shop floor to read a set whose numbers do not close. Outside in, cheapest checks first, each one clearing the ground for the next.

Madsen's Civil Drafting Technology, writing about civil work, describes the same idea for drawing standards: "Prior to the release of drawings for bids and/or construction permitting, it is important that drawings go through a final check for adherence to applicable standards." In millwork the "applicable standards" are the woodwork standard, the code, the architect's documents and the shop's own way of building. This checklist checks all four.
