How to specify a custom art installation for a hotel lobby

A lobby installation is usually the single most photographed element of a hotel — and the least standardised line in the FF&E budget. Written well, the specification protects the design, the budget and the programme. Written badly, it produces a sculpture that arrives without a mounting plan and waits three weeks for a structural engineer while the opening date does not move. Here is the process we recommend, based on what actually causes delays.

Write the specification like an engineer

Start with the site, not the object. Record the mounting substrate — concrete, blockwork, or steel stud with plywood, with a minimum of 12 mm plywood or a steel frame for anything over 50 kg — plus available fixing zones, ceiling void depth for suspended work, and power or data if the piece is lit. Then define the piece itself: overall dimensions and total weight, material and finish with a physical reference sample, fire performance of every material (EN 13501 or ASTM E84 class as the project requires), and the fixing system — concealed Z-clip rail, french cleat, threaded rod to structure, or a floor plate with chemical anchors.

Do not forget maintenance access and lighting. A suspended piece that cannot be reached for dusting will look tired within a year; a lit piece without a driver access panel will generate a maintenance call every time a unit fails. Specify the cleaning method, the relamping route and the target illuminance on the piece — 300 to 500 lux with a high colour rendering index is a workable lobby baseline — and let the lighting designer coordinate beam angles with the surface finish, because brushed metal and polished metal want completely different light.

Demand shop drawings before money moves. A credible manufacturer produces CAD shop drawings and a mounting detail for sign-off, plus a physical mockup or finish sample for anything with a bespoke surface. Sign-off on the drawing, not the rendering, is what transfers fabrication risk to the maker. The drawing is the contract; the rendering is the mood.

Budget and lead time: the real numbers

For a one-off lobby piece in metal, stone or glass at statement scale — three to eight metres — realistic budgets sit in the mid five figures in USD, with complex mixed-material walls running into six. Lead time from approved shop drawings is typically 10 to 13 weeks: two to three weeks of engineering and prototyping, six to eight of production, and one of pre-install inspection and crating. Compress that window and you pay in either money or risk; there is no third option.

Budget honestly for the edges. Crating and freight for an eight-metre suspended work can run USD 8,000 to 15,000 depending on destination and mode; a structural engineer’s review of the mounting is usually required by the owner’s insurer; and site works by the local contractor need their own line. None of these belongs inside the artwork price, and all of them should appear in the project budget from day one — the most common cause of lobby art VE is not the art, it is the forgotten logistics.

Delivery and site coordination

We deliver install-ready, which means the site work belongs to a contractor of your choice — and the specification should say so explicitly. A proper install-ready package includes a fully assembled factory inspection with photographs and measurements, modular sections numbered to match the installation manual, node drawings showing every fixing and its required substrate, and remote technical support during the site works. Your contractor needs three things from you: the manual and node drawings two weeks before the crates arrive, a confirmed substrate with tested pull-out values, and access dates that respect the crate dimensions and the building’s lift capacity. Get those three right and a complex piece goes up in days; miss them, and the most beautiful object in the project becomes the longest item on the punch list.
