How to Control Manufacturing Risks in Complex Facade Projects
Jun 14, 2026Most manufacturing risks in complex facade projects are not created in the factory.
They are usually introduced much earlier through design inconsistencies, communication gaps, coordination failures, and unclear responsibilities between project stakeholders.
The most effective way to reduce manufacturing risks is not through more inspections after production starts, but by identifying and eliminating potential issues before fabrication begins.
Several years ago, I was involved in a complex international facade project.
After the first shipment arrived on site, installation progress began to slow down unexpectedly.
At first, the project team assumed the problem was related to manufacturing quality.
However, after several rounds of investigation, we discovered that the products themselves met the required specifications.
The real issue was that different project participants had interpreted certain design details differently during the design development phase.
Small discrepancies in dimensions, tolerances, and connection details gradually accumulated throughout the project.
By the time fabrication started, the risks had already been built into the system.
That experience reinforced a lesson I have seen repeatedly throughout my career:
In complex facade projects, manufacturing risks are rarely caused by machines. More often, they are caused by information.
According to the Autodesk and FMI report Construction Disconnected, poor communication and ineffective information management account for approximately 52% of construction rework worldwide.
The same report estimates that rework typically represents 5% to 15% of total project costs.

For facade projects, the impact can be even greater.
A single design inconsistency may affect hundreds or even thousands of components.
The larger and more complex the project becomes, the more expensive these mistakes can be.
Every dimension, interface, tolerance, and installation sequence should be fully coordinated before fabrication starts.
In many cases, what appears to be a manufacturing issue is actually an unresolved design issue.
The earlier these problems are identified, the lower the overall project risk.
Drawings explain a design.
Mock-ups reveal whether the design actually works.
Physical prototypes often expose issues that are difficult to identify on a computer screen.
Many successful projects invest significant effort in mock-up testing because discovering problems before mass production is always less expensive than correcting them afterward.
BIM models, shop drawings, CNC data, and fabrication documents should all originate from the same coordinated information source.
When different teams work from different versions of information, inconsistencies become unavoidable.
Digital coordination helps reduce interpretation errors and improves overall project reliability.
Over the years, I have become increasingly convinced that successful facade projects are not defined by how advanced the factory equipment is.
They are defined by how effectively information flows between design teams, engineers, manufacturers, logistics providers, and installation crews.
The best projects do not wait for problems to appear.
They identify and manage risks long before production begins.
That is why manufacturing risk should never be viewed as a factory issue alone.
More often, it is a project management issue.
Clients often ask me:
"How can we reduce manufacturing risks in a complex facade project?"
My answer is usually straightforward:
The most effective way to solve a manufacturing problem is to prevent it from becoming a manufacturing problem in the first place.
Because once a problem reaches the production stage, the cost of correction is almost always higher than the cost of prevention.
In complex facade projects, risk is rarely manufactured.
It is usually designed, communicated, and managed long before production begins.
The biggest risk is inconsistent information between design, engineering, production, and installation teams.
Yes.
BIM improves coordination, reduces design conflicts, and ensures all stakeholders work from the same source of information.
Mock-ups help identify design, fabrication, and assembly issues before mass production begins, significantly reducing costly rework later in the project.
