The well been of human beings on construction site is very important, many man power had been lost through accidents which kills or make workers physically unfit to carry out construction activities, these in turn have multiple effects on the whole economy. Thus it is necessary to put all safety items and regulations in place before construction activities can commence. This study was carried o...

Tower cranes are major and expensive equipment that are extensively used at building construction projects and harbors for lifting heavy objects to demand points. The tower crane locating problem to position a tower crane and supply points in a building construction site for supplying all requests in minimum time, has been raised from more than twenty years ago. This problem has already been so...

INTRODUCTION Research and practice have demonstrated that decisions made prior to work at construction sites can influence construction worker safety. However, it has also been argued that most architects and design engineers possess neither the knowledge of construction safety nor the knowledge of construction processes necessary to effectively perform Construction Hazards Prevention through D...

The purpose of this study was to manage the risks of Paveh Rood Dam at constructional phase by integrating TOPSIS & RAM-D techniques. After investigating the environmental conditions of the study area and the technical specifications of the dam, the risks of the dam construction were listed in a questionnaire. After analyzing the given scores by Preliminary Hazard Analysis (PHA), Technique for ...

Off-site construction (OSC) offers a promising means to improve the efficiency of projects. However, lack experience and knowledge regarding its use results in errors design owing conflicts omissions considerations for OSC To mitigate these problems, manufacturing assembly (DfMA) is widely used include process. Several studies concerning DfMA application have been performed, but comprehensive p...

In the construction industry, material handling plays an important role. Finding proper locations for facilities not only can affect expenses, but also it impact on process of materials. Therefore, in order to supply engineering demands and materials, site layout planning problem (CSLP) within a short-distance transportation is considered as NP-hard problem. Thus, researchers are extensively us...
