Construction activity is the indicator of development. Bangladesh is now considered as a developing country leaving the group of least developed countries. Dhaka is the capital of Bangladesh with less than 170 square kilometer of area holding more than 18 million of people in its metropolitan area. For the sake of gathering a huge population, with a lot of supports and services, buildings and supports are mandatory. For the incremental demand of commercial, industrial and academic importance, the city of the democratic country is now under huge pressure of structural improvement. But, naturally in all of the sectors, construction activities must have impacts on environment, human health and communication. The study is to investigate the main environmental pollution and risks of construction activities in Dhaka city. Specifically it is to delineate the impact of construction of MRT line-6 at Mirpur to Agargaon on human and environment and a set of way forward action for reducing pollution and risk of construction. From the qualitative and quantitative study it is found that, 97% respondent’s belief in the impact on the environment, 87% confirm about air pollution and 75 % of the respondents belief in noise pollution occurring due to construction. 75% respondents know that due to air pollution from construction site people suffers from respiratory problem. And 72% respondents agree that, due to noise pollution people suffer shearing problem, HBP and other problems. 84% respondent confirm that construction activity creates communication problem in Dhaka city. 75% respondents answer that traffic jam increases for construction activity in Dhaka. 91% respondent of survey, participant of FGD and KII participants believe that if construction authority aware about this pollution and maintain proper rules, law, safety and security it is possible to mitigate those pollution from construction activity or site. So always we need to follow construction work as per RAJUK approved plan and BNBC rules and regulations.

Rezime: Arhitektura visokih zgrada zavisi od niza faktora, koji uglavnom variraju od inicijalnih ideja, funkcionalnosti projektovanog prostora, percepcije i urbanističkog konteksta, kao i vrste nosive konstrukcije i tehnoloških mogućnosti neophodnih za realizaciju željenog koncepta. Kao jedan od faktora o kojima arhitektonsko rješenje ovisi je svakako nosiva konstrukcija, koja treba da ispuni četiri osnovna zahtjeva: statičku ravnotežu, stabilnost, čvrstoću i krutost. Prekretnica za ubrzani razvoj i izgradnju visokih objekata se desila u drugoj polovini XX vijeka, kada su jake ekonomije razvijenih zemalja poduprle tehnološki razvoj u sadejstvu sa razvojem novih generacija računara i programskih paketa, koji su zajedno doprinijeli razvoju efikasnijih konstruktivnih sistema visokih zgrada. Inovativni konstruktivni sistemi u obliku cijevastih konstrukcija, outrigera (vješaljki) i diagrida (dijagonalnih mreža) i megstruktura su doprinijeli projektovanju i izgradnji visokih konstrukcija kao neizbježnom novom stilu življenja. Abstract: Architecture of high-rise buildings depends on many factors, which greatly vary from initial concepts, functionality of designed spaces, its proportions to human perception and urban context, and structural support and technological capabilities to support desired concept. Thus, in any analysis of the factors that architecture depends on is its structural support, which has to fulfill four primary structural requirements: static equilibrium, stability, strength and rigidity of the structure. A turnover for fast development in construction of high-rises occurred in the second half of the 20th century; strong economy forced and supported technological developments, and even the new generation of computers and software helped in the development of more efficient structural systems. Innovative structural systems such as tubular forms, outriggers, diagrids and megastructures enabled design and construction of high-rise structures as common thing and inevitable part of new living style.
