How to Commission a Public Sculpture: A Step-by-Step Guide
By Anand Mishra, Graphic Arts · Published 4 August 2026
Commissioning public art runs through eight stages: brief, site assessment, concept, approval of a scale model, fabrication, finishing, installation and handover. The stage that decides everything is approval of the maquette — changes are inexpensive before full-size work begins and very expensive afterwards.
Stage 1 — Write a brief that describes the problem, not the solution
The most useful brief explains what the piece is for: what it commemorates, who will see it, from where, and what you want them to feel or understand. A brief that instead specifies a solution — "a twelve-foot bronze figure" — closes off options before anyone has looked at the site.
Include the fixed constraints: budget, the date it must be in place, and any approvals already granted or still needed.
Stage 2 — Assess the site properly
Site determines scale far more reliably than budget does. A piece that is right in a courtyard disappears on a highway roundabout.
- Viewing distances and the primary approach direction.
- Sight-lines to be preserved, and existing obstructions.
- Sun path — where shadow falls, and whether the piece is backlit at the key viewing time.
- Available power, if the work is to be lit.
- Access for transport and lifting at installation.
- Ground conditions, for foundation design.
- Whether the public can touch and climb on it. Assume they will.
Stage 3 — Concept
Expect drawings or digital visuals showing the piece in its actual setting, at true scale relative to a person. A sculpture presented on a blank background tells you almost nothing useful about how it will read.
Stage 4 — Approve the maquette. This is the decision point.
A scale model — or for a portrait, a full-size clay head — is where the design becomes real and where changes are still cheap. Get every stakeholder who holds an opinion to look at it now.
Once full-size sculpting begins, the cost of change rises steeply, and once moulding starts it becomes prohibitive. Almost every troubled public art project we have seen went wrong by treating maquette approval as a formality.
If your committee or trust needs to approve iconography, proportion or likeness, this is the stage at which they must do it.
Stage 5 — Fabrication
Full-size original, moulding, casting or building, and internal structure. Ask for progress photographs at agreed points. A fabricator confident in their work will not object.
Stage 6 — Finishing
Surface treatment, patina or paint, and protective coating. Approve the finish against a physical sample rather than a photograph — metallic finishes in particular photograph very differently from how they look in daylight.
Stage 7 — Installation
Transport, plinth, foundation, anchoring and final assembly. Confirm in advance who is responsible for the plinth and the foundation, because this is the most common gap between a sculpture contract and a civil contract, and it surfaces at the worst possible moment.
Stage 8 — Handover
- Maintenance guidance: what to clean it with, what not to, and when to re-coat.
- Photographic documentation of the completed work.
- Any warranty on structure and finish.
- A named contact for repairs.
Where public art projects usually go wrong
- Approval deferred. Stakeholders who did not look at the maquette but have opinions about the finished piece.
- Site chosen after the sculpture is designed. It should be the other way round.
- Plinth and foundation in nobody’s scope. Agree this in writing at contract stage.
- Lighting as an afterthought. Decide before installation, or accept that the piece will only work in daylight.
- No maintenance plan. Public art is outdoors and unsupervised. Something must be budgeted, however small.
Frequently asked questions
How long does commissioning a public sculpture take?
Plan in months rather than weeks, and note that approval cycles usually consume more of the calendar than fabrication does. Moulding and curing are chemical processes on fixed timescales and cannot be compressed, so the realistic way to protect a fixed unveiling date is to shorten the decision stages, not the making.
Who is responsible for permissions?
Normally the commissioning body, since permissions attach to the site and the client controls it. Agree this explicitly at contract stage — it is a common and avoidable dispute.
What should be in a public art contract?
Scope with dimensions and material specified, the approval stages and who signs off each one, the payment schedule tied to those stages, who supplies the plinth and foundation, installation responsibility, warranty terms, and maintenance guidance at handover.
