30-second film
We spot it before the inspector does.
Three defects an inspector will not sign off: a missing base plate and sole board, a missing toe board and a gap in the guardrail. Found, closed and checked before handover. Then the team that keeps it that way, lift by lift, from scaffolder to engineer.

About AL-YASSIN
AL-YASSIN opens up the scaffolding knowledge that usually stays inside a few heads on site, built on *12+ *years of GCC oil and gas field experience.
oil & gasCircular column access · boarded at every lift
We think like three people at once: the scaffolder who has to build it, the inspector who has to pass it and the manager who has to pay for it.
Individual qualifications of team members. They are not company accreditations.
On the side of good practice
Safe, compliant access, measured on agreed rules and planned to the programme.
Designed, not guessed
Anything outside TG20 or TG30 compliance gets a design and a check before it is built.
Advice that works at 06:00
Plans that survive heat, permit queues, mixed-language crews and missing kit.
Every decision checkable
Weights, spacings, manpower norms and quantities, not opinions.
