A hold point is a required inspection or approval step that must be completed before fabrication can continue. Hold and other inspection points are identified in the Inspection and Test Plan (ITP). Once work reaches a hold point, the next operation cannot proceed until the designated inspector has examined the work and authorized its release. Ward’s ITP includes possible hold points from the code Authorized Inspector, customer inspector, and Ward QC. Common examples of inspection points include material identification, weld joint fit-up, internal inspection before a vessel is closed, review of nondestructive examination results, and witnessing the final pressure test.

Hold points are important because many fabrication details will be difficult or impossible to verify after work continues. For example, an internal weld cannot be directly inspected after a vessel is closed, and joint fit-up cannot be confirmed after welding. Clear communication among Production, Quality Control, the Authorized Inspector, and any customer inspector is essential to ensure that required inspections are completed without disrupting the fabrication schedule.
