3. Building Construction Process


3.1 Is this construction type addressed by codes/standards? Yes

  • If yes, provide the title of the code or standard and the year when the first code/standard addressing this type of construction had been issued? Include any applicable codes: NC 46:2014“Construcciones sismorresistentes. Requisitos para el diseño y construcción”

3.2 Are building permits required?

3.3 Explain unit construction cost: 56.19 CUC/m2

per m2 of built-up area expressed using a currency used in the region, and, if possible, an equivalent amount in $US in the brackets e.g. 200 Rs/m2 (5 $US/m2) (When calculating the conversion between local currency and U.S. dollars, please use the market rate if it is different from the official rate))
