Not construction documentation
Website text, diagrams and calculators are not a safe construction design or a certificate. Geometric results do not verify load capacity, seismic resistance, settlement, fire safety, electrical protection or sanitary compliance.
Decisions requiring professionals
Foundations, load-bearing walls, reinforcement, cable sizing, protective devices, gas lines, pipe diameters and testing arrangements require competent professionals assessing the actual project. Do not perform hazardous work from a general example.
Local requirements
Requirements in Azerbaijan and other countries may differ. Foreign references support reading and comparison; they do not replace applicable local documents or permissions.
Dangerous situations
If safety is uncertain, stop the activity and contact the responsible professional. This website is not an emergency service.
