When Quality Assurance arrangements are not robust or when checks required by Quality Control fail the consequences are not always immediately apparent. Construction activities may progress unaware of an impending issue, only to discover at some point later that NDT has not been done properly, a welder is not qualified, documentation that was assumed to be in place isn’t or possibly changes requested by engineering have not been communicated to the shop floor.

While traditional quality auditing techniques will undoubtedly identify key deficiencies during the vendor or yard qualification process, this does not address the day to day issues that arise during project execution particularly when the contractor is faced with time, resource or competency constraints.
