A Review on Using Opportunities of Augmented Reality and Virtual Reality in Construction Project Management


Augmented reality (AR) and virtual reality (VR), a kingdom-of-the-art technology for superimpos­ing information onto the real world, have recently started to have an effect on our everyday lives. In addition, AR and VR have shown a great contribution to advanced construction management in recent years. However, a comprehensive critical review of AR and VR technolo­gies in construction management is absent in the liter­ature. This study provides a comprehensive review of a summary of using potential opportunities of AR and VR to solve a variety of construction management issues effectively and efficiently. This study found that AR is successfully used in construction project scheduling, progress tracking, worker training, safety management, time and cost management, and quality and defects management. VR is effectively used as a visualization tool, worker training technology, safety management tool, and quality and defects management tool. In addi­tion, AR and VR are used for developing a network that allows the possibility of having conferences with those who are geographically far off from each other or the construction site. This study could help to explore the potential fields of using AR and VR technologies in the construction industry effectively as advance time- and cost-saving profitable tools.

Towards lean and green thinking in construction projects at Gaza Strip


Background and problem: Integrating lean and green principles while implementing construction project has become an important aspect of modern construction. Lean construction and green building are used to maxi­mize the economic benefits, address quality, reduce waste and minimize the negative environmental impacts in con­struction.

Aims: The objectives of this paper were to measure the degree of knowledge of lean and green approaches in con­struction industry in Gaza Strip and to identify the most important benefits from application of lean and green in construction.

Methodology: Literature review and questionnaire survey were used in this study. A total of 155 copies of the questionnaire were distributed randomly to owners, con­sultants and contractors in the Gaza Strip, and 119 copies of the questionnaire were received.

Results: The results revealed that the awareness level of lean and green construction by owners, consultants and contractors in the construction industry in Gaza Strip is moderate. There are very important benefits of applying lean and green construction such as “reduce non-useful work that does not add value to work”, “reduce the environmental impact of the construction process” and “saving the money needed to complete the project”.

Conclusions: It was concluded that integrating both concepts on projects showed that lean leads to green but not necessarily vice versa. The fields of lean and green thinking, however, have been developed largely independent of each other. There is a big gap in the knowledge and application of the lean construction and the green application.
