Reading an architect's set to draw from

Where the millwork information hides in an architect's drawings and specification, what to extract before you draw, and the questions to ask on day one.

12 min read

You are handed an interior elevation and told to draw the millwork. The elevation is the smallest part of what you need. The rest is spread across a dozen other sheets, several disciplines and a specification book, and nobody will point you to it. This chapter is the map.

It covers how an architect's set is organised, where each piece of millwork information lives, how to read the specification section for casework, and what to extract and ask before you draw a line. The worked example is a real, published university casework specification.

Drawings and specifications are one document

The US National CAD Standard puts it in two definitions. Drawings are "graphic and textual information … for the purpose of conveying data about a specific portion of a project". Specifications "define the qualitative requirements for products, materials, and workmanship on which the construction contract is based". It calls them "complementary documents". The drawing shows where and what shape. The specification says what it is made of, how well, and what you have to submit.

A drafter who reads only the drawings misses half the contract. The Woodwork Institute's sample set makes the point on its specification sheet: "Shop drawings must include all items required in original specifications."

How an architect's set is organised

The order of the disciplines

Under the National CAD Standard, a set runs in discipline order. The Architect's Guide to the U.S. National CAD Standard gives the typical order: cover sheet, then General, Hazardous Materials, Survey, Geotechnical, Civil Works, Civil, Landscape, Structural, Architectural, Interiors, Equipment, Fire Protection, Plumbing, Process, Mechanical, Electrical, Telecommunications, Resource, Other, Contractor/Shop Drawings, Operations. For millwork, the ones that matter most are:

LetterDisciplineWhat you look for
GGeneralDrawing index, symbols legend, abbreviations, code information
AArchitecturalFloor plans, reflected ceiling plans, wall types, door schedule, details
IInteriorsInterior elevations, finish plans and schedules, millwork design details
QEquipmentAppliances and equipment your cabinets must house
PPlumbingSinks, rough-in locations
EElectricalOutlets, data, lighting in or near the millwork
RResourceExisting conditions and items by others, for coordination only

The same guide notes that General sheets carry information that "applies to all sheets in the drawing set", including the "drawing sheet index, symbol legend" and code information. Resource sheets hold information that is "not a part of the contract work", with "kitchen equipment furnished by others" given as a typical use. Read both. The first tells you how to read everything else. The second tells you what someone else is supplying into your openings.

Reading a sheet number

A National CAD Standard sheet number carries its own address. A-201 means Architectural, sheet type 2, first sheet. The sheet type digit tells you what kind of drawing is on it before you open it:

DigitSheet typeMillwork use
0GeneralLegends, notes, abbreviations
1PlansLocation and extent of every item
2ElevationsThe look, where the architect draws it
3SectionsWall sections: what your work fixes to
4Large-scale viewsEnlarged plans and interior elevations
5DetailsThe architect's millwork details: design intent
6Schedules and diagramsFinishes, doors, hardware, wall types
93DRenderings: what the client thinks they are getting

So a millwork design detail in a set like this lives on an A-5xx or I-5xx sheet, and a finish schedule on an A-6xx or I-6xx. Not every firm follows the standard. One design studio's published Revit template uses its own series instead: 100 plans, including finishes; 200 reflected ceiling plans; 300 elevations; 400 sections; 500 details, "Millwork, Joinery"; 600 schedules and specifications. The first sheet to read is the index on the General sheet, whatever system the firm uses.

A few of these deserve a closer look.

The finish schedule

Elevations name finishes by code, not by product. The code resolves in a schedule. The template checklist above describes a "room finish matrix" linking rooms to floor, wall, ceiling and baseboard finishes. The university specification in the worked example below sends you elsewhere again: "See Section 09 06 00 for color and finish information" for plastic laminate and wood. Follow every code to the product before you draw a section. A laminate and a veneer need different edges and different backing sheets.

The reflected ceiling plan

An outsourcing vendor's article lists reflected ceiling plans among the plans a millwork set includes, to show the relationship "between millwork and ceiling elements like soffits, coves, or bulkheads". The ceiling decides how tall a tall cabinet can be, whether an upper run stops at a bulkhead, and where a light fitting lands on your top. One of the job sheets bundled with the Woodwork Institute sample shows exactly this: upper cabinets under a "finished gyp. bd. soffit by others", with a ceiling scribe dimensioned at the end of the run.

Wall types and blocking

Your cabinets hang on something. The wall type schedule says what: stud size, board layers, fire rating. The blocking inside that wall is usually someone else's work. The Woodwork Institute sample's general notes say "all blocking for cabinet anchorage is by others". AWI 100 requires your drawings to show "blocking or strapping requirements and their locations (blocking to be furnished by others) shown on cabinet elevations with dimensions above finished floor" (§3.2.3.1 f). So you locate blocking you do not install, on walls you did not design. Get the wall types right first.

Other trades' sheets

The specification in the worked example tells the installer to "verify location and sizes of utility rough-in", and to fit grommets in countertops "over knee spaces that have power and/or data outlets located below countertop level". Both need the plumbing and electrical sheets read against your elevations before you draw a single cut-out.

The specification section

Finding it

Specifications are organised by MasterFormat, a list of numbered sections. The National CAD Standard describes it as a list "primarily used to organize project manuals and detailed cost information, and relate drawing notations to specifications". The worked example below is Section 06 41 00, Architectural Wood Casework. Its own list of related sections shows where else to look on that job: 06 10 00 Rough Carpentry for "support framing, grounds, and concealed blocking", 12 36 00 Countertops, 08 80 00 Glazing, 07 90 05 Joint Sealers. Read the related sections too. The countertop and the blocking are often not in your section at all.

How a section is laid out

A specification section has three parts. Each hands you something different:

PartHoldsWhat the drafter takes from it
Part 1 GeneralScope, related sections, definitions, submittals, quality assurance, mock-ups, field conditionsWhat the set must contain, minimum scales, samples, who measures the site
Part 2 ProductsMaterials, grades, laminates, hardware, fabricationEvery thickness, every edge, every hinge on your sections
Part 3 ExecutionExamination, installation, adjusting, cleaningInstall tolerances and what must be verified on site

Worked example: one real casework section

The University of Texas at Dallas publishes its design guidelines, including Section 06 41 00, Architectural Wood Casework, issued 21 June 2011. It is eight pages long. Here is what it changes on a set of shop drawings. Every line below is a clause in that section.

ClauseWhat it saysWhat it changes on your drawings
1.3 DefinitionsBottoms of cases more than 4'-0" above the floor count as exposed. Tops of cases 6'-6" or more above the floor count as concealed.The finish on an upper cabinet's bottom panel, and on a tall cabinet's top
1.5 Submittals"Minimum Scale of Detail Drawings: 3" to 1'." Provide the information required by the AWI/AWMAC/WI Architectural Woodwork Standards.Your detail scale, and your checklist
1.5 SamplesAfter laminate or veneer approval, a 6" × 6" door sample "showing edges, core, and specified … finish applied"A sample to build and label, and the edge you draw must match it
1.7 Mock-upA typical base cabinet and wall cabinet, with hardware and finishesThose two cabinets must be fully detailed early
1.10 Field conditions"Field measure conditions where woodwork is indicated to be fitted to other construction… Show final field measurements on shop drawings."A revision after site measure, before fabrication
2.2 MaterialsMDF structural panels at least 3/4" thick; backs, drawer parts and bottoms at least 1/2"; MDF shelves not allowed in open cabinets or in cabinets 32" wide or moreEvery thickness in every section; the shelf material in wide cabinets
2.3 CabinetsVeneer cabinets Premium grade; plastic laminate cabinets Custom gradeTwo grades on one job, by cabinet type
2.5 LaminatesHorizontal surfaces other than countertops HGS 0.048"; vertical VGS 0.028"; backer BKL 0.020"Laminate callouts on every section
2.8 HardwareConcealed self-closing hinges, "minimum 110° swing"; side-mounted 3/4-extension slides; wire pulls on 4" centresClearances at door swing and drawer travel; pull boring
2.9 FabricationDoors over 6' high: 1 3/8" thick. Counter butt joints at least 2' from sink cut-outs. Backsplash fixed with brackets at 16" on centre.Tall door sections; top joint locations on plan; splash detail
3.2 InstallationScribe "with maximum gaps of 1/32"". "Do not use additional overlay trim for this purpose."Scribe allowance on every end panel and filler; no cover trim

None of that appears on an interior elevation. All of it decides what you draw. A drafter who starts from the elevation draws 1 1/2" details, a single grade, a butt joint wherever the top runs out, and a trim strip to hide the scribe. Each of those breaks a clause above.

Put the specification on a sheet

The Woodwork Institute sample shows the answer. Its second sheet is a "Specification Requirements" table: case body, door and drawer fronts, drawer box, shelves, counter tops and hardware, each with its material, thickness, joinery, edge banding and product number. A reviewer can check your reading of the specification against one sheet. A bench hand can see the rules without the book. Build that sheet first, from the specification, before you draw anything else.

Where you cannot meet the specification, do not draw around it. AWI 100 says changes and substitutions drawn into shop drawings "do not constitute a request for approval". They must be "itemized separately from the shop drawings", with the reason and "the anticipated impact to schedule, cost, and possible impact to other trades" (§3.2 b–c).

Tie your drawings to theirs

The architect's set has references you can use. One of the job sheets bundled with the Woodwork Institute sample titles its shop section with the architect's detail it answers: L1/A/A501 (SIM.). A reviewer can lay the two side by side. The residential set in hand has a REF: field under every view title for the same purpose, and leaves every one blank.

Fill it in. For each of your views, note the architect's plan, elevation or detail it came from. It costs a minute per view. When the architect revises a sheet, your list tells you which of your drawings to check.

The National CAD Standard also warns that notes "should not include vague references such as 'SEE SPECIFICATIONS'". Apply that to your own set. "Per spec" on a shop drawing sends the bench hand to a book they do not have. Write the requirement.

What to extract before you draw

Make one list, on paper or in a spreadsheet, before you open CAD:

  1. Sheet list. Every architect's sheet that shows millwork, by number and revision date.
  2. Item list. Every millwork item, its room, and the plan, elevation and detail that show it.
  3. Grade by item, from the specification.
  4. Finishes by item, resolved from code to product.
  5. Materials and thicknesses, from Part 2.
  6. Hardware, by make and model, from Part 2 or the hardware schedule.
  7. Items by others that fit into your work: appliances, sinks, equipment, lighting, with models where known.
  8. Walls and ceilings at every item: wall type, blocking, soffit, ceiling height.
  9. Submittal rules, from Part 1: scales, samples, mock-ups, field measurement, the standard named.
  10. Conflicts: every place where a drawing and the specification, or two drawings, disagree.

Item 10 becomes your first set of questions.

Questions to ask on day one, not week three

AWI 100 says the manufacturer "is encouraged to make technical suggestions and raise questions with the design professional" (§3.2 b). Ask early, in writing, while an answer costs nothing. Several are visible in the sets in hand:

  • Which standard, which edition, which grade, for which item? The Woodwork Institute's project data sheet gives tops, cabinets, millwork and doors a grade each. If the specification is silent for an item, ask.
  • Who supplies and locates blocking? If it is by others, you still show it. Confirm the wall type it goes into.
  • Which appliance, exactly? The residential set dimensions an ice maker and beverage cooler opening and a printer cabinet, each with "verify fitment". That note says the fit was not confirmed when the set went out. Ask for model numbers and cut sheets before the openings are set.
  • Which sink and fittings? AWI 100 asks for sink "size, type, mounting, and location if provided to manufacturer/supplier prior to shop drawing submittal" (§3.2.3.6 c). Get them provided.
  • Are finishes selected? The residential set makes finish approval a condition of fabrication on every sheet. If selections are still open, say so in the transmittal.
  • When can the site be measured? The worked example requires field measurements on the shop drawings, and the HVAC system "complete and operational for minimum 7 days prior to installation". Both affect when your final revision can go out.
  • Where do the drawings and the specification disagree? List each conflict with sheet and clause. Ask which governs. Do not choose silently.

Every question you ask on day one is an assumption you do not have to draw. Chapter 24 covers writing them so they get answered.

Before you leave the architect's set

Check the revision date on every architect's sheet you used, and note it on your sheet list. The set you drew from is the set you will be measured against. If the architect issues a revision, your sheet list tells you exactly what to recheck.
