The building construction industry faces challenges, such as increasing project complexity and scope requirements, but shorter deadlines. Additionally, economic uncertainty and rising business competition with a subsequent decrease in profit margins for the industry demands the development of new approaches to construction management. However, the building construction sector relies on practice...

In the 21st century, knowledge has become one of the management paradigms which determines the organization competitiveness. Therefore, construction companies strive to strengthen the capacity of organization by introducing the knowledge management. However, the current knowledge management system applied in the construction industry is operated without a business process. Hence it could not pr...

As the energy use by commercial buildings continues to grow, there is a need to develop innovative techniques to reduce and optimize energy use in buildings. In recent years, Building Energy Management Systems (BEMS) have gained popularity because of increasing interest in building energy conservation and savings. However, most of the current BEMS are limited to the functions of collecting and ...

Contour Crafting is an emerging technology that uses robotics to construct free form building structures by repeatedly laying down layers of material such as concrete. The Contour Crafting technology scales up automated additive fabrication from building small industrial parts to constructing buildings. Tool path planning and optimization for Contour Crafting benefit the technology by increasin...

309 The 3-Dimensional Modular Unit Construction System involves constructing ao in fixed cycle time using b) 3-D Modular Unit Building Blocks which are assembled at a c) ' factory automated staging area on the jobsite prior to being lifted into place on the building. This system has great potential to facilitate the use of robots on the jobsite and dramatically reduce the construction period. I...

Prefabricated construction, a new direction for the future development of the Chinese construction industry, can maximize the requirements of “green”. As a new form of green building, prefabricated construction is of particular interest. On account of the immature development of the green building market in China, the investment risk for prefabricated construction is higher than for traditional...

background and purpose: in a recent century, the amount of construction waste has increased significantly. although the building industry has a considerable role in the development of a society, it is regarded as an environmentally destructive. source reduction is the highest goal in the waste management hierarchy and is in priority. it also has economic benefits by reducing costs associated wi...

Objectives: Because of the high rates of accidents, the construction industry has become a hazardous industry in Iran and therefore paying more attention is required. This paper investigates safety management in construction companies for improving workers’ safety as one of the ergonomics aims. Methods: In order to survey the safety management in construction companies a questionnaire was pr...
