Dimensional review
Ask the inspector to measure the floor diagonals and hole patterns against the released drawing. The inspection record should include the instrument, measured value, drawing tolerance and disposition for any exception.
China sourcing coordination
BOXABL provides independent procurement coordination in China for prefabricated residential houses and expandable units. This site is independent of the original brand and has no dealership authorization. We organize evidence from candidate suppliers and the buyer’s specialists so open items can be identified before committing to a quote.
A quotation is comparable when the same building use, foundation interface, finish scope and destination appear in every supplier response.
The buyer sets commercial priorities and approves substitutions. Suppliers are responsible for what they manufacture and issue. A locally qualified project team confirms the relevant requirements and the acceptable path to approval. Inspection and freight firms act within their written scope.
The gallery illustrates four review settings a buyer may request during supplier screening. Confirm what can be observed, which revision controls the inspection, and how deviations are recorded. An inspection visit has its own scope and does not replace an independent laboratory test when one is required.
Ask the inspector to measure the floor diagonals and hole patterns against the released drawing. The inspection record should include the instrument, measured value, drawing tolerance and disposition for any exception.
A galvanized or painted coupon can help identify the proposed finish. For coastal orders, request coating mass or dry film thickness as applicable, preparation details and the repair method for cut edges or welded areas.
Compare EPS, PIR and rock wool samples by thickness, mass and supplier conductivity data. For a claimed fire resistance rating, confirm that the evidence represents the joint and opening details in the proposed wall.
A mock-up can show where plumbing and cable trays cross the marriage line. Ask both the module supplier and installer to mark their work on the same interface drawing before pricing a finished bathroom.
Identify the intended product, country and quantity before asking for records. Ask the supplier to label each file with its date and revision so later substitutions remain traceable.
Separate wind speed in m/s, ground snow load in kN/m² and seismic inputs. Add the source and revision of each criterion so a buyer’s local engineer can confirm it.
Request core, thickness, conductivity, joint detail and any assembly test reference. Use the same column definitions when comparing supplier responses.
Ask for packed dimensions, loading positions and lifting points. The forwarder can use this information to check the container loading plan and identify routing constraints.
Name the decisions still open on your project and the documents already available. We can help turn those gaps into questions for suppliers.
