Fabrication is where the exhibition moves from paper to physical reality. It is the phase where design decisions are tested against materials, tolerances, and time — and where budget overruns are born if not caught early.
By the end of design development, the exhibition exists completely on paper. Fabrication is the process of turning those documents into physical exhibits that will be shipped to a museum, installed in the gallery, and experienced by visitors. It is the most complex project management phase in the exhibition design process.
The steps of fabrication are similar regardless of museum type. What changes is the mix of trades involved — a science center with complex interactives requires more software engineering and electronics; a history exhibition with artifact cases requires more conservation-grade fabrication. But the workflow — working drawings, fabricator selection, oversight, quality control, shipping — remains consistent.
Working drawings are the construction documents of the exhibition world — the complete, dimensioned, specification-level drawings from which a fabricator builds. They differ from design development drawings in precision and completeness: every joint, every dimension, every material, every fastener is specified.
Working drawings typically include: dimensioned plan and elevation drawings for every exhibit component; electrical and data drawings; AV equipment rack layouts and wiring diagrams; graphic production files at final size; finish and material specifications; and hardware schedules. The package should be complete enough that a qualified fabricator could build the exhibition without contacting the designer for clarification.
Design development drawings communicate intent and allow cost estimation. Working drawings communicate construction — they are the legal documents of the fabrication contract. The distinction matters when disputes arise: ambiguity in working drawings is the designer's problem; ambiguity in design development drawings is a negotiation.
Full floor plan at 1/4" = 1' or metric equivalent, with all exhibit positions dimensioned from fixed reference points. Include column locations, door swings, electrical panel clearances, and ADA clear floor space zones.
Every exhibit face shown in elevation with all dimensions, material call-outs, and finish designations. Sections through complex casework, interactives, or structures. Ceiling sections showing lighting positions and heights.
Equipment schedules for all AV, interactive, and technology components. Rack layout drawings. Cable routing diagrams. Conduit and pull box locations in the floor plan. Software and content specifications for interactive elements.
All graphics at final production size, in production-ready file formats. Bleed, registration, and substrate specifications included. Color managed and proofed against the fabricator's printing system.
Fabricator selection is one of the most consequential decisions in the exhibition process. The fabricator is responsible for translating the working drawings into physical exhibits — a process that typically represents 60–80% of the total exhibition budget. A fabricator mismatch produces budget overruns, quality problems, and schedule failures that no amount of oversight can fully correct.
Send the complete working drawing set with a formal request for proposal. The bid package should specify the scope of work, bid format requirements, schedule milestones, insurance and bonding requirements, and the evaluation criteria the museum will use to select a fabricator.
Request references from three recent museum projects of similar scale and complexity. Visit the fabricator's facility if possible. Review their shop drawings from previous projects — shop drawing quality is a strong predictor of fabrication quality. The lowest bid from a fabricator without relevant experience is rarely the best value.
The fabrication contract should specify deliverables, payment milestones tied to fabrication progress, quality standards, change order procedures, and warranty terms. A vague contract is an invitation to scope creep and disputes. Museum fabrication contracts should always include a warranty period of at least one year post-installation.
Before fabrication begins, the fabricator produces shop drawings — their interpretation of the working drawings, showing how they intend to build each component. Review shop drawings carefully against the working drawings. Approving a shop drawing with a discrepancy creates a change order; missing a discrepancy creates a rebuild.
Fabrication oversight is active participation in the build process — not passive waiting for delivery. Regular site visits to the fabrication facility, review of construction progress against the schedule, and resolution of questions in real time prevent the accumulation of problems that only surface at installation.
Before any exhibit component leaves the fabrication facility, it should be reviewed against the working drawings and the approved samples. A pre-ship review — conducted at the fabricator's facility with the designer and museum project manager present — is the last opportunity to correct problems without the time pressure of an active installation.
The pre-ship review should confirm that every exhibit functions as designed, that all finishes match approved samples, that all graphics are correctly produced, and that all AV and interactive content is loaded and operating. Components that fail the pre-ship review should be corrected before shipping — not flagged as "punch list items" to be resolved on site.
Too often museums err on the side of low interactivity out of fear of maintenance issues, rather than building updateability and changeability into the exhibits from the start. The right time to design for maintainability is in the working drawings — not after the first element breaks on the installation floor.
Exhibition components must survive shipping and — if the exhibition will travel — multiple installations. Crating is an engineering problem, not an afterthought. The fabricator should provide custom-built crates with internal fixtures that hold each component securely, with documented packing procedures that allow reinstallation by a different crew.
Document every crate: photograph the packed contents, record the crate dimensions and weight, and create a crate-to-exhibit map that allows any team member to identify which exhibit is in which crate without opening it. This documentation becomes the installation sequence guide in Phase IV.
Anyone who thinks that exhibition design is the creation of drawings is only one quarter correct. The process starts before drawing and continues through to the installation of the exhibits.
