Most engineering resources stay shallow. Ours go all the way: worked, checked, and shown page by page before you buy.
Every product shows real pages and its full contents. You know exactly what you are paying for.
Calculations are worked step by step and checked, and every practice answer is explained, so you learn the reason.
Written from scratch. Nothing copied from codes, standards or exam papers, and no affiliation with any code body.
Written by an engineer on oil and gas projects, with the mistakes to avoid. One payment, yours to keep.
Each collection is a complete set for one skill: Project Controls, QA/QC and Mechanical.
For planning engineers, project control engineers, schedulers, and anyone moving into planning.
For welding, coating, piping and in-service inspectors and QA/QC engineers.
For mechanical and piping engineers on industrial and oil and gas projects.
Complete sets for one role, for less than buying separately.
