The design and drawings in the country are generally based on Code of Practice of USA, UK, EU and BANGLADESH named as Bangladesh National Building Code (BNBC). The construction activities are carried out as per specifications of the contract presently based on Federation Internationale Des lngenieurs Conseils (FIDIC).

The consultant or employer's engineers responsible for preparing designs and drawings do not generally send drawings in time, there by delaying the project implementation. After drawings are sent to sites, various mistakes are found on the drawings which are to be corrected. The contractors in our country generally do not
