First of all, before inspection and preparing inspection report there are some basic requirments. For any areas of inspection you must be expert of scope, well educated, certified or trained. Then able to write, to touch, to smell, to see, to hear, to think. But sometime the experince more important than others. Even you work hard at site to inspect aircraft, pipe mill, pipe line, welding, ship building, towers, bridges, huge costructions, spacecraft the most important part of the inspection activities is the good prepared Inspection report.
How to prepare inspection report?
Inspection report is the technical and literary make up of your job. But this make up can not be clean up. This make up is permanent in your work carrier. So how should inspection report be prepaired. First Inspection report should be simple, understandable by client or by your boss. It should include introduction, progress and result. But it is not a literary novel or romantic poem, allways use simple and technical words. Most of your reports shoud include numbers, standards, process, procedures, test plans, technical feed backs etc. Use your beautiful words in sections of comments, concerns, remarks, informations, advises etc.
Inspection report should include item below;
- Date and place
- Introduce yourself and attendies of inspection activities
- PO, Spec, ITP numbers
- Contact details
- Other ID datas requeted by Clint
- Purpose of inspection visit
- Inspection summary and findings
- ITP Steps
- Shop tour
- Areas of concerns
- Action required
- Calibration records
- Document Status
- HSE issues
