Every unit follows an inspection and test plan: material certificates, dimensional checks, welding and coating records, integrated system tests and a signed release. The ITP is the working document behind the finish.
An Inspection and Test Plan names each activity, the reference document, the acceptance criterion, the record and who must witness it. It is issued for the project, not copied from a brochure.
The production template is adapted to the product type: pre-engineered building, demountable container or panelized building. The issued revision follows the destination code, the customer specification and the factory that will build the unit.
Where a project requires third-party inspection, the same ITP becomes the interface with the inspector: notification, hold points, witness signatures and closure of findings.
Work stops until the QA/QC representative attends and signs.
The inspector is notified; the activity may proceed if they do not attend.
Documents and records are reviewed before the next stage.
Document approval, material approval and incoming inspection are reviewed before production starts.
Each checkpoint produces a named record. The record set becomes the Manufacturing Data Record.
The sequence separates design intent, material identity, fabrication quality, envelope protection, system integration and release. A failed gate creates a nonconformance before the next stage begins.
The project ITP is frozen against approved drawings, calculations, the material list and the code basis for the destination market.
Steel, panels, coatings, doors, electrical equipment and cooling components are checked against the purchase order before they enter production.
Cutting, bending, drilling and welding are inspected against the drawing, with welding procedure and welder qualification records retained.
Surface preparation, galvanizing, powder coating and panel joints are inspected as separate hold points before the unit is closed up.
Power, cooling, fire detection, monitoring, grounding and interlocks are tested as a working system, not as separate packages.
The MDR is reviewed, open NCRs are closed and the unit is released with a signed certificate, packing list and shipping marks.
A typical production plan for a modular unit. The project ITP may add tests for the destination market, the cooling architecture or the client's own specification.
H = hold point, W = witness point, R = document review. Codes and inspection frequency are fixed in the issued project ITP; the table is a reference scope, not a substitute for that document.
The MDR is compiled unit by unit. It is the file a client, an EPC or a third-party inspector reads to understand what was checked, by whom and against which revision.
A release certificate is issued after the record set is complete and open findings are closed.
Current revision, load summary and project ITP.
Mill certificates, CoC and heat-number traceability.
Inspection forms, quarantine and storage checks.
WPS, PQR, welder qualification and VT/MT reports.
Surface preparation, DFT, adhesion and impact checks.
Frame, panel, door, window and stair checklists.
Insulation, continuity, grounding, pressure and leak tests.
Power, cooling, fire, monitoring, alarm and interlock results.
Open items, disposition, corrective action and closure.
Release certificate, packing list, shipping marks and O&M.
The MDR is released with the project package. The website does not host project quality records or downloadable files.
Modular housing and modular data centers enter North America through different approval routes. The page separates the whole-system route, the third-party factory route and the component certificates.
NEC NFPA 70 Article 646 addresses modular data centers. UL 2755, the Outline of Investigation for modular data centers, is the whole-system framework referenced for the evaluation. A project review typically covers electrical distribution, structural and transport integrity, cooling, life safety and cross-system interlocks.

We prepare the design narrative, test plan and ITP records to support a project-specific evaluation. UL 2755 certification is configuration-specific and is confirmed with the certification body before any claim is made.
Intertek's published modular building program covers plan review, in-plant inspection, the Intertek certification label with state insignia, and ongoing compliance audits. Its reference standards include CSA A277, CSA Z240 MH / RV, CAN/UL 2600, NFPA 1192 and ANSI A119.5.

Program participation is agreed per factory and project. The page describes the third-party pathway; it does not state that every LEGEND unit carries an Intertek label.
US states use different combinations of state plan review, third-party plan review, state inspection and local inspection. The authority having jurisdiction (AHJ) confirms which route applies to the project address and occupancy.

Approval routes and lead times vary by state, county and city. The project team confirms the route in writing before drawings are frozen.
Framing, panels, generators, transformers, batteries and switchgear can carry their own evaluation or certification. These documents support the design but do not certify the complete cabin or the integrated site.

Each certificate is read against its holder, product family and validity. The certificate register on the compliance page records those limits.
Construction documents checked against the adopted code.
Factory quality and compliance audits during production.
Intertek label with the state insignia where the program applies.
Continued compliance checks after the initial certification.

A component certificate is not a whole-unit certificate. A factory certification is not a site approval. A UL 2755 evaluation is configuration-specific. We state the scope of each document rather than turning it into a general compliance claim.
The template is a starting point. The issued ITP follows the product type, destination code and customer specification.
A unit is released when the MDR is complete and open NCRs are closed, not when the production schedule says it is finished.
Certificates are described by holder, product and configuration. A component certificate is never presented as a whole-unit certificate.
Our modular data center solutions integrate equipment from established technology suppliers. Selection, compatibility and warranty are confirmed project by project.
Supplier names describe the equipment ecosystem, not an authorization to use their marks.
Send the project location, product type and the standard or client specification you need to satisfy. We reply with the applicable ITP scope and document list.
