Factory vs Site Quality Control: Key Differences in Facade and Glass Projects

Quality control in aluminium and glass façade projects doesn’t happen only at the construction site. In fact, it begins much earlier – inside the factory. Both stages are equally important, but the approach and focus are different. Let’s break down the key differences.

Factory Quality ControlAt the factory, the focus is on materials and fabrication. Aluminium profiles, glass panels, and hardware are inspected for dimensions, finish, and compliance with specifications. Welds are tested, assemblies are trial-fitted, and coating or anodizing quality is checked. Packaging and labeling are also verified to ensure safe delivery to site. The aim is to make sure that what leaves the factory is defect-free and ready for installation.

Site Quality ControlOn-site, the focus shifts to installation and performance. Engineers must verify that mullions, transoms, and brackets are aligned, level, and securely fixed. Sealants and gaskets are checked for proper application. Functional tests – such as water leakage and air infiltration checks – are carried out to confirm that the system performs under real conditions. Documentation like MIRs, WIRs, and NCRs becomes critical at this stage for approvals and handover.

Why Both MatterIf factory QC is weak, defective materials will reach the site. If site QC is ignored, even the best factory work will fail in performance. That’s why engineers must understand how to balance both stages.

For civil engineers, quantity surveyors, and site professionals, mastering these differences is essential. The Bhadanis Aluminium, Facades & Glassworks Quality Control & Assurance Engineering
