Under what circumstances is third-party inspection justified on commercial coating work?

From Billy Russell of D&R COATING INSPECTION on March 12, 2014:
I disagree. Under NO circumstances should an owner rely on a contractor's own QC to carry out QA/QC. Verify everything with an independent 3rd party. Projects are only warrantied for 1 year. You can spray a dirt parking lot and lock the gate come back in a year to find little or nothing wrong, but 5 years from now on a steel structure--then you start seeing what kind of job you got for the money. Never rely on a contractor's QC reports; verify it yourself !

On every project or in daily affairs, the function of a third party is very important, because it enables checks and balances, provided the third party is not biased.

From Kumar Kolur Vadivelu of Sadara Chemical Company on March 9, 2014:
 Circumstances requiring third-party inspection might include 1) a complicated project requiring different type of coatings; 2) the applicator is  new to the particular coating material; 3) insurance requirements because of legal concerns. If  these circumstances are not critical, then contractor QC may be enough to carry out QA/QC activity for an effective painting program.

From Bryan Zofkie of Aerco Sandblasting Co. on March 3, 2014:
I couldn’t agree more with both Mr. Halliwell and Mr. Russell in that QA/QC is the last thing you want to short-change on a coating project. At the same time I also think there is something to be said about the contractor performing the work. If you as the owner have experience with this contractor, and know the contractor is  knowledgeable and experienced with the application system as well as  QA/QC procedures (much like a third-party inspector would perform), then I am not sure a third party inspector is completely necessary. On the other hand, if this is a new contractor or even a new coating product or procedure for an experienced contractor, I think at a minimum a manufacturer's representative should be involved if a third party inspector is not feasible.

From M. Halliwell of Thurber Engineering Ltd. on February 13, 2014:
I think that any time there could be significant problems (be it financial, time, or just plain challenges to getting the job done) should a coating system fail, then making use of third-party inspection can be justified. I also think Billy is "on the money." If the job could be a problem, then the Owner can pay a bit more now for a QA/QC program or potentially a lot more later if/when the job needs to be redone. I also agree that the third-party inspectors need to be held accountable for their work.  If they aren't, then where's the motivation to do a good job?

From Billy Russell of D&R COATING INSPECTION on February 12, 2014:
I believe that third-party inspection is justified at a projects inception to ensure compliance with the specifications, as well as with coating manufacturers recommendations in order to ensure the life of the coating system. That being said, inspection firms should be held liable for their inspection reports to the owner. Bonding should be required of inspection firms  on projects. If there is a coating failure or if claims are filed, inspection firms as well as the contractor should be held accountable.  Then the games will end.

From Timothy McCoy of Chester Engineers on February 11, 2014:
I believe that 3rd party inspection is justified whenever an owner wants to be assured that he is getting what he is paying for! I use the analogy, you can pay me now, or pay me (usually much more) later. Don't save money on a project by cutting a good QA/QC program!
