COATINGSPRO MARCH 2017 19 the owner that they will have a corro- sion problem with the present design, as critical areas cannot be blasted or coated. e fabricator has offered a repair solution to the owner that includes caulking of the raw edges, butt joints, gaps, and stitch welds. I have been asked to comment on the repair procedure. I am not an engineer and do not wish to overstep my boundaries by contradicting an engineer. Is there a NACE guideline for fabrication of steel structures that I could refer my owner to? A: If you were hired as an inspec- tor, be honest with the owner and tell him or her that is beyond the scope of work you were contracted for and you are not comfortable with making recommendations. If the owner is looking for a 30-year service life, without looking at the contract, the contractor and/or the coating manufacturer are responsible to make sure the specifications will meet the project requirements. ere is probably a warranty involved, and the company backing the warranty should be respon- sible for approving the specifications. It is your job to make sure the specifica- tions are followed. T he ow ner may need to hire a consultant, who should be paid much more than the inspector. T his is because he is taking on a liability when he writes or approves a specifi- cation. If you make recommendations, you are assuming responsibility for the project. Make it clear to the owner that you will be happy to make sure the project conforms to the project specifications, but you are not qualified to write those specifications. It sounds like a good opportunity to get all the parties involved and have a pre-construction meeting. Good luck! A: If size of the skid permits, you may suggest them to galvanize. A: e ISO 12944 Part 3, ISO 8501 Part 3, and NORSOK M-501 standards could help you. microns (8.1 mils), the DFT is not being achieved. However, for higher W FT, the corresponding DFT achieved is almost in the expected range. T he blast profile is 75 microns (3.0 mils). W hat could be the reasons for this?
