How to control the quality of overseas prefabricated projects?
Quality control of overseas prefabricated projects cannot just rely on a quick glance before leaving the factory. It requires the establishment of checkpoints throughout the entire process from drawings, materials, samples, production, packaging, cabinet loading, arrival, installation and maintenance.
Summary
This article explains quality control methods for overseas modular construction, prefabricated interior and furniture projects. GODA recommends writing quality requirements into BOQ, samples, production records, packaging and installation acceptance documents.

Quality problems often start with unclear scope
If the materials, specifications, dimensions, tolerances, hardware, packaging and acceptance standards are not clearly written, it will be difficult to determine whether they are right or wrong during later quality inspection.
GODA will write the quality requirements into the BOQ and sample confirmation instead of waiting to find problems after production is completed.
Define the criteria first, then check the results.
At the factory stage, samples, materials and processes must be controlled
Factory quality inspection should include material incoming, dimensional processing, pre-assembly and trial fitting, surface treatment, hardware installation, functional testing and photographic records.
Batch projects especially require first-piece confirmation to avoid errors being replicated in batches.
Material confirmation
Sheets, finishes, hardware, colours, environmental and fire ratings.
Dimensional craftsmanship
Drilling, tolerances, edge sealing, welding, painting and pre-assembly trial fitting.
Functional testing
Doors, windows, hardware, lights, power supplies, drainage and removable parts.
Packaging and cabinet loading are also quality controls
Many damages occur during transportation, so packaging protection, cabinet fixation, box numbering and cabinet photos are all within the scope of quality inspection.
If the box number and room number cannot be traced after the product arrives, problem handling will be very slow.
Confirm product, quantity, serial number and vulnerability protection.
Record the order of packing, fixing method and packing list.
Accept, take photos, and record defects according to the list.
Reissue, replace and close issues by number.
On-site acceptance must be bound to the installation sequence
On-site acceptance, installation acceptance and final delivery should be separated. Many products arrive fine, but installation errors can cause subsequent quality issues.
GODA recommends documenting issues with a checklist and photos so that the manufacturer, installation team and customer can track responsibility.
Single point inspection
It is difficult to cover installation and maintenance risks by only inspecting the equipment before leaving the factory or on site.
Whole process quality control
From prototype, production, packaging, cabinet loading, installation to maintenance and continuous inspection.
Are third-party inspections required for overseas projects?
For complex or high-volume projects, it is recommended to use third-party or independent quality inspection, but the prerequisite is that the acceptance criteria must be clearly written in advance.
Is sample confirmation necessary?
Very necessary. Samples can confirm materials, colors, hardware, nodes and installation methods in advance.
How does GODA help with quality control?
Assist with control through BOQ, samples, quality inspection photos, cabinet loading records, on-site acceptance and problem lists.

Next Step
If you are worried about the quality of overseas projects, you can first write the acceptance criteria into the BOQ.
GODA will assist in organizing quality inspection lists for the sample, material, production, packaging, cabinet loading, installation and maintenance phases.
