7 topics across all disciplines.
Inspection and quality control — ITPs, hold points and NCRs
How work gets inspected and accepted on an EPC project. What an inspection and test plan is, the difference between a hold point and a witness point, what a non-conformance report does, and why the disposition is an engineering decision rather than an inspector's.
Welding processes, WPS and NDT — what happens before an arc is struck
SMAW, GTAW, GMAW and the rest, explained by what they are good at. Then the paperwork that makes a weld legal — WPS, PQR and welder qualification — and how welds are inspected.
Non-destructive examination — choosing the method and reading the result
Why every NDE method is blind to something, what magnetic particle cannot do on stainless, why ultrasonics can miss a crack lying the wrong way, the difference between an indication and a defect, and why the examiner's qualification is part of the result.
Concrete and reinforcement — why the mix is the easy part
What concrete grade actually means, why the water-cement ratio decides almost everything, what cover is protecting, and why curing is the most neglected step on site.
Placing, curing and testing concrete in hot weather
Why curing is a chemical requirement rather than a finishing touch, what evaporation rate does to a slab before it has set, how cube specimens must be made and stored to mean anything, what the acceptance criteria actually say, and why a cold joint is a structural defect rather than a cosmetic one.
Calibration and accuracy — what a certificate actually proves
The difference between ranging a smart transmitter and calibrating it, why as-found readings matter more than as-left ones, what turndown does to accuracy, how hysteresis hides from a one-direction check, and why traceability is what turns a number into evidence.
Analysers and sampling systems — where the real problem usually is
What an analyser measures that a transmitter cannot, why the sample system causes most of the failures, how transport lag limits what you can control, and why the take-off point decides everything.
