Define the fabrication package before release
A fabrication request should be built from current, approved project documents. The release package typically identifies:
- piping isometrics, spool drawings and revision status;
- line classes, material specifications and bills of material;
- welding, examination and traceability requirements;
- dimensional tolerances and field-weld allowances;
- heat treatment, coating or insulation requirements;
- inspection hold points and release documentation; and
- delivery sequence, identification and preservation needs.
CNC coordinates the handoffs between the project team, qualified fabricator and field crew. Applicable code responsibility, design authority, quality approvals and inspection acceptance must be named in the contract documents rather than assumed.
Field installation by CNC
Once released components reach the site, CNC can perform the assigned receiving, handling, fit-up, installation, support and tie-in activities. The exact scope depends on drawings, access, isolation, equipment interfaces and the planned operating window.
Installation may connect with CNC’s process piping, pipe supports and tubing and hydrostatic testing services. Connections to vessels or machinery can also require coordination with boilermaking or millwright services.

Quality records and turnover
Material documentation, fabrication records, examination reports, treatment records, field installation records and test packages should follow a project-defined turnover index. CNC reviews required handoffs and compiles the records assigned to its scope. It does not claim responsibility for documents or approvals assigned to a fabricator, inspector, engineer or owner.
Information for an RFQ
Provide drawings, specifications, line and spool lists, materials, code and examination requirements, partner qualification criteria, delivery dates and field-installation scope. Include site access, laydown, lifts, tie-ins, isolation, supports, testing and required turnover records.
