Public Art Sculpture: What the Commission Actually Involves
Public art is the most procedurally demanding category we work in. The sculpture itself is often the easy part; the commission usually runs through an arts committee or percent-for-art programme, a planning authority, a structural reviewer, a maintenance department and a public consultation. D&Z works as the fabrication and engineering partner in that process — for cities, developers, arts consultants and for artists who have won a commission and need a factory that can build it to code.
Three Ways These Projects Reach Us
Artist fabrication
An artist or studio has the concept and needs it built. We work from your 3D files, drawings or maquette, engineer it for the site, and fabricate under NDA. Authorship stays entirely yours; we do not market work made this way.
Design-and-build commissions
The client has a site, a budget and a theme, and asks us to propose the piece. Concept renders are free and we revise until the committee is satisfied.
Catalogue pieces adapted to a site
An existing design rescaled, refinished or reproportioned for a specific location. The fastest and cheapest route when the brief is open.
The Documentation a Public Commission Will Ask For
Expect to be asked for most of this, and budget the time for it:
- Wind-load and structural calculations to the governing local code
- Base-plate, anchor-bolt and foundation loading drawings for the civil engineer
- Material certificates and weld procedure records
- Finish specification and expected weathering behaviour
- A written maintenance schedule for the client’s facilities team
- Expected service life and a repair strategy for impact or graffiti damage
We issue all of it as a package. Stamping by a locally registered engineer is normally required in the project’s own jurisdiction, and we support that review directly with whoever you appoint.
Designing for a Public Audience
Three constraints shape almost every public piece. First, contact: anything within reach will be touched, leaned on and climbed, so low-level detailing is rounded, thickened and fixed with tamper-proof hardware. Second, sightlines: the work has to resolve from the angles people actually approach from, which is rarely the angle it looks best in a render, so we test the model against real site photography. Third, maintenance capacity: a piece that needs quarterly specialist attention will not get it. We steer public clients toward Corten, brushed stainless and bronze precisely because a municipal maintenance budget can sustain them.
Safety, Durability and Service Life
Public installations are designed to a longer service life than commercial ones — we target 50 years plus for stainless, bronze and Corten work. That means 316 stainless anywhere near salt, full-penetration welds at structural joints, stainless or galvanised internal frames rather than painted mild steel, and drainage designed so water cannot sit inside a hollow form and freeze. Where a piece incorporates lighting, water or moving parts, we provide accessible service points rather than sealed assemblies that have to be cut open.
Budget and Programme Planning
For programme purposes, a mid-size public commission (4-8 m, fabricated metal) typically runs three to five months from approved design to delivery, plus four to eight weeks of sea freight. Add four to twelve weeks at the front for committee approval cycles, which in our experience is the least predictable part of the schedule. Bronze figurative work adds one to three months for clay modelling. We can work to a fixed delivery date and will tell you honestly at quotation whether it is achievable.
Public Art FAQ
Do you work confidentially for artists and studios?
Yes. NDA as standard, no use of the work in our marketing, and no contact with your client.
Can you meet a percent-for-art or public procurement specification?
Yes. Send the specification and we will respond against it clause by clause, including material certificates, welding standards and insurance requirements.
Who is responsible for installation?
Usually a local contractor, working to our drawings. We supply the installation manual, anchor templates and lifting plan, and provide remote supervision or send a technician for complex lifts.
What happens if the piece is damaged after installation?
We supply a repair procedure with the handover documents. Bronze and stainless can be repaired in place by a competent local fabricator; for major damage we can produce replacement sections from the original files, which we archive.
