Building Regulations, Codes and Standards
This domain tests the legal hierarchy you rely on and where each instrument bites: the Law of the Engineering Organisation and Building Control (قانون نظام مهندسی و کنترل ساختمان, 1374), its implementing by-law, the National Building Regulations (مباحث), national standards (استانداردهای ملی), and municipal and detailed-plan controls including the Article 100 commission (کمیسیون ماده ۱۰۰).
The hierarchy
- Statute and by-law: create the professional licence (پروانه اشتغال) with grades and disciplines, and the duty of building control.
- National Building Regulations: technical content, chapter by chapter - definitions, administration, fire, general requirements, materials, loads, foundations, masonry, concrete, steel, industrialised building, site safety, mechanical, electrical, lifts, health, energy and maintenance.
- National standards: product and test specifications referenced by the regulations.
- Municipal instruments: building permit, detailed plan, supervision reports and the occupancy certificate (پایانکار).
- Article 100 commission: handles violations of the permit - unauthorised area, extra floors, encroachment - and may order fines or demolition.
Worked example
A builder adds an extra floor beyond the permit. The supervisor must not certify the stage; a written report goes to the municipality, which refers the matter to the Article 100 commission. The commission assesses the violation and decides between a fine and demolition, subject to the applicable limits. Your professional exposure is the risk that you continue reporting compliance after the breach - silence reads as approval.
Traps
Treating the regulations as voluntary guidance. Ignoring the detailed plan because the national code is satisfied. Assuming a licence in one discipline authorises work in another. Believing grade and capacity limits (ظرفیت اشتغال) are administrative formalities with no effect on the validity of your signature.
