Building Codes, Regulations, and Professional Practice
This domain tests the legal skeleton of Iranian building work: the مقررات ملی ساختمان (National Building Regulations), the قانون نظام مهندسی و کنترل ساختمان and its آییننامه, the permit process, and the statutory duties of designer, supervisor (ناظر) and contractor (مجری).
Core rules
- Know the volume map: مبحث ۱ definitions, ۲ administrative system, ۳ fire, ۴ general requirements, ۵ materials, ۶ loads, ۷ foundations, ۸ masonry, ۹ concrete, ۱۰ steel, ۱۱ industrialised construction, ۱۲ site safety, ۱۳ electrical, ۱۴ heating and ventilation, ۱۵ lifts, ۱۶ plumbing, ۱۷ gas, ۱۸ sound insulation, ۱۹ energy, ۲۲ building maintenance.
- Practice is controlled by registration: an engineer holds a صلاحیت (design, supervision, execution, calculation) and stamps drawings only within it.
- The supervisor inspects at defined stages, records non-conformities in writing, and withholds confirmation when work departs from approved drawings. The supervisor cannot redesign.
- Any change to approved drawings requires the original designer and a revised permit; the شناسنامه فنی و ملکی records what was actually built.
Worked example
A client wants to convert a residential floor to offices. The reasoning chain is: change of use → new permit and revised drawings from the designer → re-check of egress, fire resistance and stair capacity under مبحث ۳ → parking and density re-checked against the طرح تفصیلی → supervisor's written confirmation of the executed work. Skipping the permit step because the structure is unchanged is the classic error: occupancy, not structure, is what changed.
Traps
- Confusing the supervisor's inspection duty with the contractor's execution duty.
- Assuming a building permit covers later additions.
- Believing municipal approval can override a مبحث requirement.
- Signing off work verbally instead of recording non-conformity in writing.
