# How Long Does an Interactive Installation Take to Build? A Realistic Timeline > A reskinned proven interaction can ship in a few weeks. A custom mechanical or AI-driven installation needs roughly two to three months from brief to opening, because prototyping, duty-cycle testing and rehearsal cannot be compressed. In practice what moves the opening date is client-side decision speed, not build speed. **Published:** 2026-08-20 - **By:** MLABART ## The five phases Every project runs these phases. They overlap, but none can be skipped: | Phase | What happens | Blocked by | | --- | --- | --- | | Concept and feasibility | Interaction defined, venue surveyed, power and rigging checked, approach costed | Venue access for survey; agreement on what the piece must achieve | | Engineering and prototype | Mechanics designed, sensing selected and bench-tested, structure engineered | Sign-off on the interaction -- changing it here restarts the phase | | Content production | Real-time application built, visual content produced to brand guidelines | Brand asset delivery and the review-round count | | Fabrication and factory test | Structure built, systems integrated, run tested at the workshop before shipping | Long-lead components; nothing else can compress this | | Install, commission, rehearse | On-site build, calibration to real conditions, rehearsal with real people | Venue access windows and other trades finishing first | ## Three timeline tiers How long a project takes depends far more on which tier it sits in than on how hard anyone works: - Proven module, custom skin -- an existing interaction mechanic with new visuals and a new enclosure. Weeks, not months. This is the tier to choose when the date is already close. - Custom flagship -- a bespoke mechanical reveal, a purpose-built AI experience, an installation engineered for one venue. Engage at least two to three months before opening so prototyping, duty-cycle testing and rehearsal all fit. - Full exhibition hall or long-run immersive space -- multiple integrated installations, architectural coordination, permanent-grade reliability. A project of its own scale, planned in quarters rather than weeks. ## What actually causes delays Across projects, delays cluster in the same places -- and most of them sit on the client side of the table, which is good news, because they are controllable: - Late interaction sign-off -- the single biggest one. Changing what the piece does after engineering has started resets the engineering phase, and it is invisible until the schedule slips. - Brand assets arriving late -- product 3D files, final packaging, approved artwork. Content production cannot start on placeholders and then simply swap them at the end. - Review rounds nobody counted -- two rounds and five rounds are different schedules. Fix the number in the plan, with named approvers. - Venue access windows -- malls and convention centres often give overnight-only install slots, and other trades run late ahead of you. - Power and rigging sign-off -- load calculations and hanging point approvals routinely take longer than the client expects, especially in malls. - Customs and shipping for cross-border work -- a solvable problem, but it needs time, not just budget. ## What can be compressed, and what cannot Being honest about this is the difference between a tight schedule and a failed opening: | Activity | Compressible? | How, or why not | | --- | --- | --- | | Fabrication | Partly | Parallel workshops and pre-ordered long-lead parts | | Content production | Partly | Proven templates and a fixed review-round count | | Interaction design | Yes, by choosing | Take a proven mechanic instead of inventing one | | Duty-cycle testing | No | Time under load is the test; there is no shortcut | | On-site commissioning | No | Real light, real floors, real crowds only exist on site | | Rehearsal | No | A one-shot reveal has no second take | ## If the date is fixed and close This is a common situation and it is workable, provided the trade-offs are made deliberately rather than discovered late: - Move down a tier -- choose a proven mechanic with a custom skin rather than a bespoke build. The audience experiences the finish, not the novelty of the engineering. - Cut the number of pieces, not the engineering on each. One reliable flagship beats three half-tested moments. - Freeze the interaction immediately and put the remaining flexibility into content, which stays editable much later. - Name the approvers and the review-round count on day one. - Protect rehearsal in the schedule first and build everything else backwards from it -- not the other way round. ## Rehearsal is a phase, not a buffer The most common scheduling error is treating rehearsal as slack to be consumed when earlier phases run late. It is where the failures that matter are found: the lighting cue that blinds the sensor, the queue that forms in the wrong place, the reveal that lands two seconds after the music. For a one-shot moment -- a launch reveal, a keynote unveiling -- there is no second take, so rehearsal is the deliverable. For a long run, the equivalent is duty-cycle testing before shipping: the ROLEX "Oyster Story" kinetic installation ran roughly ten hours a day for nineteen consecutive days without fault, and that outcome was decided months earlier at the test rig, not on site. ## FAQ ### What is the minimum lead time for an interactive installation? A proven interaction mechanic with a custom skin can be delivered in a few weeks. Anything involving bespoke mechanics, new AI experiences or a long run needs roughly two to three months so that prototyping, duty-cycle testing and rehearsal all fit before opening. ### Can fabrication and content production run in parallel? Yes, and they normally do -- but only after the interaction is frozen. Both phases depend on the same definition of what the piece does, so parallelising before sign-off usually creates rework rather than saving time. ### Why does the vendor need a site survey so early? Power capacity, rigging points, load limits, floor conditions, ambient light and the install access window all change the engineering, not just the price. Discovering any of them late converts a design problem into an on-site problem, which is the expensive kind. ### How much time should be reserved for on-site commissioning? Enough to calibrate under the venue's real lighting and to rehearse with actual people, plus contingency for other trades running late ahead of you. It is the phase most often squeezed and the one where squeezing shows most visibly on opening day. ### What is the fastest way to shorten a timeline without risking the opening? Move down a tier rather than compressing engineering: take a proven interaction mechanic and invest the remaining time in finish, content and rehearsal. Cutting testing or rehearsal to protect a bespoke build is the trade that most often fails publicly. ## Related Pages **See also:** [Product Launch Reveal Stages](https://mlabart.com/solutions/product-launch-reveals/) | [Kinetic Installations](https://mlabart.com/solutions/kinetic-mechanical-installations/) | [Immersive Art Exhibitions](https://mlabart.com/solutions/immersive-exhibitions/) | [Digital Exhibition Halls & Showrooms](https://mlabart.com/solutions/digital-exhibition-halls/) --- **MLABART** -- Interaction - Imagination - Innovation MLABART is a creative technology studio specializing in interactive installations, digital multimedia art, and immersive experiences.
