Technology for construction industry of Bangladesh

Abstract

The Indus Valley civilization shows that, Indian sub"continent had a leadership in the advancement in construction Technology and Industry over the world. But unfortunately this part of the sub-continent especially Bangladesh could not cope with the modern technological advancement. Construction technologies can, on the basis of their content of labor and equipment, be classified as equipment intensive, labor intensive and labor based technology. In recent years, technological innovation in design, analysis, construction materials, construction methods, etc have resulted in significant changes in construction industry. Computer aids have improved capabilities for generating worth designs, reducing th,} time requirement to produce alternative designs to ensure safety with economy. New technologies not only have enhanced the quality of construction but also have shortened the time for shop fabrication and field erection. Construction methods have advanced through various stages of mechanization and automation, including the latest development of construction robotics. That means trend is advanced technology. In this study, 25 numbers of six to nine storied buildings and 4 numbers of twenty to thirty storied buildings have been studied. It has been observed that, the construction industry in Bangladesh dominated by labor-intensive technology, lower grade material and primitive construction procedure. In most of the cases 29% more cost involvement has been observed. These made construction indl1stry of Bangladesh an inefficient one. Use of high quality material easily saves huge monitory loss in this sector. This will require active participation of Engineers in design house and in field. Further detail study may enhance this fact elaborately. Different sizes 10 numbers building of different excavation depth have been studied. Of these considering PWD st£ jard rate of works; it has been observed that for deeper excavation, excavator or equipment intensive technology is cheaper than labour intensive excavation. For ending conclusion of equipment intensive excavation require, further detailed investigation. Bangladesh cOl1ld regain leadership in the construction industry, over the world through accepting and participating in the advancement of the modern technologies. The scopes are waiting ahead. Entrepreneur, especially the Engineers should come forward to take the challenge to advance Bangladesh in that direction.
