Fibre Reinforced Facade Encyclopedia: Manufacturing
Lead time is the elapsed period between award of a facade package and the first delivery of panels to site. For moulded composite facades it is dominated by process time rather than by material supply: shop drawing production and approval, tooling manufacture, sample and prototype approval, production cycles governed by mould count and cure, then shipping and site delivery sequencing. Understanding which of those steps is on the critical path is the difference between a programme that can be compressed and one that cannot.
The panel itself takes a day or two to make. Everything else in the lead time is approvals, tooling and mould cycles.
At a glance
| Property | Typical value | Note |
|---|---|---|
| Shop drawings and model | Weeks; the first item on the critical path | |
| Approval cycles | Each review round adds elapsed time | Usually the largest single variable on a project |
| Mould manufacture | Driven by mould count and complexity | |
| Sampling and prototype approval | Runs partly in parallel with tooling | |
| Cure time, cementitious | About 7 days moist cure unless polymer modified | GRCA requirement; a fixed process duration |
| Demould cycle | Typically 16 to 24 hours per mould | Sets how many panels a mould delivers per week |
| Production rate | Panel count divided by moulds times cycles per week | The arithmetic that sets production duration |
| Sea freight, Batam to Australia | Transit plus port and quarantine handling | |
| Total, award to first delivery | Indicative industry range 6 to 16 weeks for moulded facade work |
The shape of the critical path
A facade lead time is a chain, and only some links can be shortened. In order: shop drawings and the fabrication model, approval of those drawings, tooling design and mould manufacture, sample and prototype approval, production, quality control and packing, then freight and delivery sequenced to the installation programme.
The links behave differently. Shop drawings and approvals are elastic and are where most lost time occurs. Tooling is semi-elastic: more moulds can be built in parallel if the money is available and the geometry is resolved. Production is arithmetic, set by mould count, cycles per mould per week and panel count. Cure time is fixed by chemistry and cannot be bought down. Freight is fixed by distance and by the shipping schedule.
Shop drawings and approvals
This is the first item on the critical path and the one most often underestimated. The manufacturer has to convert an architectural intent model into a fabrication model: every panel individually numbered, set out against the structural grid, with its anchor positions, joint widths, edge returns, rib layout and tolerance allowances resolved. On freeform or doubly curved facades this is a substantial modelling exercise before a single drawing is issued.
Then it is reviewed. Each review round is elapsed time: issue, review by the architect, review by the facade consultant, review by the structural engineer for the anchor and substructure interface, comment consolidation, revision, reissue. Two rounds is normal. Four rounds is common where the interface with the structure or the setting out was not resolved before award.
The efficient way to shorten this is not to draw faster. It is to reduce the number of open questions at award: confirmed structural setting out, confirmed anchor zones, confirmed joint widths, a single finish specification, and a nominated approver with authority to sign.
Tooling: mould count is the hidden number
Tooling is where programme, cost and geometry meet. The number of moulds a project needs is the panel count divided by the number of cycles each mould can deliver before the last panel is required, and cycle time is dominated by the demould age.
That arithmetic produces some counter-intuitive results. A facade with four hundred panels of one type needs far fewer moulds than a facade with forty panels in ten types, even though the second is smaller. Reducing the number of distinct panel types, or designing a family of panels that share one mould with removable inserts, buys more programme than any other design decision available to an architect after concept stage.
Production, cure and quality control
Production time is the most predictable part of the chain, and the least compressible per panel. A panel is cast, left overnight, demoulded, cured, finished, inspected and packed. Cementitious panels need about seven days of moist cure unless the mix is polymer modified and designed for air cure; resin laminates need their post-cure. Those durations are chemistry and they do not respond to commercial pressure.
What does respond is parallelism. Two moulds halve the production duration of a panel type. Finishing and quality control run behind casting rather than after it. Batch testing for modulus of rupture and limit of proportionality runs alongside production rather than gating it. A factory with spare mould capacity can compress a programme; a factory at capacity cannot, regardless of what is promised.
Freight, delivery sequence and site
Panels made offshore add sea freight, port handling, customs and quarantine to the chain. ShapeShift manufactures in Batam, Indonesia, with head office in Queensland, so Australian projects carry a shipping leg that has to be planned into the programme rather than discovered at the end of it. Air freight exists as an emergency measure and is priced accordingly for large moulded panels.
- Confirm the installation sequence before production starts, not after
- Agree stillage and stacking arrangements, because they affect how many panels fit in a container
- Allow for site storage or for just in time delivery with the crane booked
- Allow for replacement panels: damage in transit and on site happens, and a replacement runs a full mould cycle
What actually compresses a programme
Three things, in order of effect. First, freezing geometry early, because every downstream step depends on a stable model and every change reruns part of the chain. Second, reducing the number of distinct panel types, because that reduces mould count, tooling cost and production duration simultaneously. Third, running approvals in parallel: finish samples approved against the mix while shop drawings are still in review, structural approval of anchors ahead of full drawing approval, prototype panel approval scheduled the week the mould is completed rather than a month later.

Questions specifiers ask
How long is the lead time for moulded facade panels?
It depends on panel count, the number of distinct panel types and the approval process. Industry ranges of six to sixteen weeks from approved shop drawings are commonly quoted for moulded facade work. For a project specific figure, ask.
What is usually on the critical path?
Shop drawing approval first, then tooling. Production is arithmetic once mould count is fixed, and cure time is a fixed process duration that cannot be shortened.
Can lead time be shortened by paying more?
Partly. More money buys more moulds, which shortens production, and it can buy faster tooling. It does not shorten a seven day moist cure, and it does not shorten an approval cycle.
Why does the number of panel types matter so much?
Because mould count is driven by types, not by area. Forty panel types in small runs need far more tooling, and far more programme, than four hundred identical panels.
Does offshore manufacture add much time?
It adds a sea freight leg plus port, customs and quarantine handling, which has to be planned into the programme. It does not change the manufacturing durations, which are set by cure and mould cycles wherever the factory is.
