Manufacturing & quality

From approved drawings to an identifiable kit.

A Ready-to-Assemble SIP Kit brings manufacturing information and physical components together. Explore material preparation, CNC machining, identification and packing—and define the checks and records needed for your particular order.

01 / Production sequence

Prepare, manufacture, identify, hand over.

Quacent BV coordinates the supply discussion; the production organisation in China carries out the agreed manufacturing scope. One approved drawing issue links materials, openings, quantities and connections. The sequence below shows the preparation and control points to define for the order.

  1. 01

    Release the information

    Agree the drawing revision, supply schedule and approval responsibilities. Resolve changes before separate versions reach production.

  2. 02

    Specify the inputs

    Identify the panel facings, core and connection materials. Establish which supplier documents and material references are needed.

  3. 03

    Prepare the panels

    Connect panel preparation with the specified build-up. Confirm the production operations and checks relevant to those elements.

  4. 04

    Machine the geometry

    CNC preparation translates approved dimensions and openings into components. Machining follows the design review; it does not replace it.

  5. 05

    Check agreed details

    Define dimensional, opening and connection checks against stated criteria. A tolerance needs a specification and an agreed checking method.

  6. 06

    Identify the components

    Use element references that the project team can connect to the current layout. Keep the identifying information legible through handling.

  7. 07

    Reconcile and pack

    Match the agreed quantities and package references to the supply. Confirm protection, packing information and any outstanding items.

  8. 08

    Prepare the handover

    Provide the agreed documents and records for dispatch and receipt. Connect questions to a named contact and the relevant component reference.

02 / Consistency before cutting

The same kit in the drawings and on the floor.

Factory preparation begins with a consistent definition of the kit. The panel materials, geometry and connection members need to refer to the same supply schedule and released drawing set. An opening or connection change can affect more than the single panel on which it appears.

Before production release, identify who approves the information and how revisions will be communicated. When a detail changes, review the affected elements, associated documents and implications for the preparation or delivery programme. That record gives the production team a clear reference to work from.

The prepared components shown here belong to the physical side of that process. The released documents connect material specifications, dimensions and component references so the supply can be identified and checked against the order.

03 / Useful records

A check should lead back to a component.

Numbering becomes useful when a reference can be followed from the drawing to the element, its package and any specified record. The receiving team can then discuss an identified item rather than trying to recognise it from a photograph alone.

Agree the level of traceability needed for procurement and site acceptance. Depending on the order, this may involve material references, dimensional records, photographs or an independent inspection. Availability, method, timing, responsibility and cost belong in the agreed scope.

What is checked?
Name the element, material, dimension or quantity and its drawing revision.
Against which requirement?
State the acceptance criterion and how it will be assessed.
Where is the result recorded?
Connect the result and any follow-up decision to the same component or package reference.

04 / Evidence for the intended application

Different documents answer different questions.

A factory management certificate, material document, assembly test and project calculation describe different things. Bring the designer’s evidence requirements into the supply discussion early so the proposed build-up and intended use can be reviewed against the right documents.

Management systems

Request current certificates for the relevant production organisation and confirm the named entity, site, scope, standard edition and validity. These concern the management system covered—not automatic approval of every building application.

Materials

Check which facing, core and connection materials a document identifies, and whether those references match the intended supply. A material property is not automatically the result for a whole wall, roof or floor.

Product & assembly evidence

Ask which panel build-up, connections, linings and application a report covers. Changes to the tested assembly may need further assessment rather than a copied performance claim.

Project-specific review

The building’s structural, thermal, fire and acoustic requirements need the relevant local design review. Confirm who checks applicability, addresses interfaces and accepts the required documents.

Reading management-system references

ISO 9001 concerns quality management, ISO 14001 environmental management and ISO 45001 occupational health and safety management. These links explain the standards; they are not Quacent certificates. Request the applicable production-organisation documents for your procurement review.

05 / Inspection and handover

Agree the checking route before dispatch.

Identify any independent inspection or required reporting before ordering, including the stage at which it must take place and who accepts the results. This allows the inspection to be planned around the production sequence rather than added after the shipment is ready.

For a discrepancy, record the element reference, drawing revision and clear photographs. Distinguish missing documentation from physical damage or a mismatched component. Agree the review and resolution before the affected part is installed or modified; keep the accepted decision with the relevant record.

At handover, the contractor needs the current assembly information, package references and the agreed reporting contact. These practical links carry the preparation work through to receipt and assembly on site.
