The Costs of Accidents in Qatar, Oman, and Saudi Arabia Construction Industry by Tariq Umar Abstract: Considering the construction projects and the current status of occupational safety in the Gulf Cooperation Council (GCC) region, this article attempts to estimate the costs of accidents in construction. The parameters used in these estimates include the values of the current projects in the three main countries including Qatar, Oman, and Saudi Arabia; and the amount disbursed by the government organizations against injuries, disabilities, and deaths. The total costs of an accident in Oman are estimated at US$ 415,620 with an economic burden of US$ 205.73 Million/year. In Saudi Arabia, the costs of an accident are estimated at US$ 91,940, while the economic burden of the Saudi economy is estimated at US$ 261.11 Million/year. Similarly, the costs of an accident in the Qatari construction industry stand at US$ 205,526. The costs of an accident in these countries are quite higher than the costs in the USA, UK, AUS, and SA. Keywords: Health & Safety; Costs of Accident; Direct costs; Indirect costs; Construction industry; Qatar; Oman; Saudi Arabia.
BIM: blockchain interface framework for the construction industry by Malla Vijayeta Abstract: The Construction industry contributes a noteworthy role in the economic development of a nation and the extensive usage of Building Information Modelling in Built Environment paved a podium for information exchange and digitisation. However, owing to the constraint of sole mechanism and dearth of apprehension of truthful facts, the construction industry issues cannot be rooted out completely. Block chain technology is a contemporary regionalised record database management system which bore the backbone of the development of a Bitcoin system and has powerful performance on
updating of data, information repository and security minded approach. This paper investigates the fundamental philosophies and usage of these two domains in the construction industry using literature survey. On amalgamation of these two domains, the author develops an interaction matrix throughout the Life Cycle of a Project which enables the management of data in a secure, transparent and appropriate decentralised common Information Technology environment. Keywords: BIM; building information modelling; block chain; ledger; transaction; data management; decentralisation; networks; interface; BIM functionality; smart contract; interaction matrix.
Building Information Modeling (BIM) for Structural Components in Construction by B.D. Hilton, S. Azhar, Malik Khalfan, I. UlHaq Abstract: This research was conducted to explore the use of the structural Building Information Models, as they relate to shop drawings and fabrication, during the construction phase of the project. The use of BIM has been widely accepted as a time saving tool in the architecture and engineering design community for several years. This research attempts to help further identify obstacles that have been preventing the use of BIM on United States Army Corps of Engineers (USACE) construction projects beyond the design phase. Data was collected by survey from firms that work with the Army Corps of Engineers. The survey questions were designed to gather an overall understanding of BIM, its use, the structural aspects of the model, Level of Development (LOD), and funding options. All survey participants had the opportunity to provide additional comments. The data was then analyzed to determine trends and limitations. It was found that the key obstacles preventing the use of structural BIM modeling, during construction on Army Corps of Engineers projects, were the required level of development to produce shop and fabrication sheets, and the statutory limitations on design dollars. Although BIM has reached a technical level, for designers, they all indicated that the available design funds falls short of what is needed to produce the LOD required. Keywords: Structural aspects of the BIM model; Level of Development (LOD); United States Army Corps of Engineers (USACE) construction projectsrn.
