Writing a Millwork Spec Section a Fabricator Can Actually Bid

Most millwork specifications are long and still leave the decisions that matter unmade. A section a fabricator can bid is specific about a short list of things.

Millwork specifications tend to be long and still leave unmade the decisions that determine both cost and appearance. Length is not the problem. Boilerplate covering subjects the standards already cover, alongside silence on the project-specific decisions, is the problem.

A section a fabricator can actually bid is specific about a short list of things.

Scope, Stated by Assembly

Begin by naming what is in the section, by assembly type and drawing reference, and naming what is specified elsewhere.

This single paragraph prevents the most expensive category of error. Wall paneling, feature stairs, wood ceilings, and closet interiors all get assumed into and out of millwork scope depending on who is reading. Say where each one lives.

Grade, by Scope

Name the AWI grade, name the edition, and assign grades by scope rather than globally. Premium for the identified feature elevations, Custom for general casework, Economy for back-of-house is a defensible and cost-effective structure.

Add a precedence clause stating what governs where the drawings and the standard conflict.

Materials, Including the Cut

Species alone is insufficient. State the cut — plain, rift, quarter, or rift and quarter — and state whether characteristic figure such as ray fleck is required, permitted, or excluded.

State the substrate requirement where it matters, and the finished thickness of exposed veneer faces.

Match and Sequence

If the work is veneered and visible, state the match type, whether the sequence continues across panels, and reference the elevation that shows the layout.

Match type without a layout drawing is not a specification. It is a preference the shop will implement according to its own judgment.

Finish, as a System

State the system, the sheen as a measured number, the color reference, and the surface preparation requirement. Require approved finished samples on the specified substrate before production finishing.

Hardware, by Model

List manufacturers and model numbers for hinges, slides, pulls, and any specialty mechanism, with load ratings where drawer sizes warrant. Generic hardware call-outs are priced generically and supplied generically.

Tolerances and Interfaces

State the reveal dimensions that are design-critical rather than leaving them to shop standard. State which condition governs where two tolerances conflict — level top line versus consistent base, most commonly.

Submittals, With a Schedule

Require shop drawings showing grain direction, match layout, joint locations, hardware, and field-verified dimensions. Require samples. And state the review duration you will actually meet.

That last item is a courtesy that pays for itself. Fabrication is scheduled in slots, and a review that overruns its stated window costs the project a slot.

What to Leave Out

Resist specifying construction methods the standards already govern and the shop knows better than you do. Joinery, carcass assembly, and fastening are the fabricator's expertise.

A section that is precise about intent and quiet about means produces comparable bids from shops using different methods to reach the same result. That is the objective.

The Test Before Issuing

Read the section as though you were pricing it, with no access to the designer and no knowledge of the project beyond the documents.

For each assembly, can you determine the species, the cut, the treatment of natural figure, the match, the finish system and sheen, the hardware, the grade, and the reveal dimensions? Can you tell which scope is in this section and which is elsewhere? Do you know how long the review will take and when fabrication is expected to release?

Anything you cannot answer is something each bidder will answer differently, and the spread in the numbers will be the cost of that ambiguity rather than a real difference in the work.

Length Is Not the Measure

A short section that answers those questions is a better specification than a long one that recites the standards back at the reader.

Most of what makes millwork expensive to procure is not stringency; it is uncertainty. Bidders price uncertainty as risk, and risk carries a premium that buys the project nothing.

Removing the ambiguity usually lowers the number and raises the quality at the same time, which is an unusual combination and the reason this work is worth doing carefully.
