Response Method, based on the requirements of the Bangladesh National
Building Code as a minimum, or other approved, internationally
recognized standard.
4.4.7 Materials
Materials shall be durable and fit for purpose. Materials for external surfaces
shall be selected for aesthetic qualities and proven durability to withstand all
