The BIM system
- The BIM system is a technological system that has multiple dimensions, reaching up to 7D and in some international classifications reaching up to 10D, and the efficiency of BIM technology increases in carrying out its practical tasks when applying the 4D and 5D dimensions, which relate to the collaboration between work teams and coordinating tasks between them to control the two most important dimensions, which are time and cost.
- The main goal of the BIM system is to provide all the data and information related to each building, which will contribute to the performance of engineers, technicians, managers, building operators, and make it easier for owners and users to use.
- The use of BIM 4D and 5D ensures the application of BIM technology during the implementation and design stages together by providing all the information related to building elements and details for different work teams of engineers, technicians, construction managers, and consultants, which greatly contributes to avoiding any problems during the implementation process.
- One of the key roles of BIM 4D and 5D technology is coordinating between the implementation and design teams at the same time clarifying the modifications that are made during the construction process and presenting all the emergency considerations that arise during the building process.
- One of the most tangible benefits of applying BIM during implementation stages is reducing material losses and saving time for various engineering projects significantly and clearly, by using distinctive 4D and 5D tools that detect errors, contradictions, or obstacles before the implementation team reaches them, which contributes to providing early solutions and prevents delays in construction work and avoids any budget deviations for the project.
- One of the most prominent tangible results that highlighted the importance and advantage of using BIM 4D and 5D is completing a large number of engineering projects that implemented the BIM system without the need to increase the budget, except by a slight amount not exceeding 0.1%. However, various engineering projects over the past years before implementing the BIM system were forced to apply a cost increase margin for a single project by more than 30% sometimes reaching up to 50%.
- These great results played a major role in companies’ interest in implementing BIM technology, especially BIM 4D and 5D, to ensure a high level of commitment to the budget and avoid delays in delivering within the specified deadlines.
Some of the most famous applications that have been implemented in reality for BIM 4D and 5D include:
- Construction of large facilities
- Major construction companies such as Tumer Construction and Skanska are among the first companies to commit to applying BIM technology in building hospitals and airports, where the technology helped improve the planning and execution stages and reduce any possibility of errors and delays in delivery within the specified deadlines.
- Infrastructure projects
- Railway and highway projects are among the prominent projects that require the use of BIM 4D and 5D technology to ensure coordination between all work teams responsible for the project, especially subcontractors, and to ensure compliance with the project’s specified schedule and cost.
- Commercial and residential buildings
- Developing commercial and residential buildings is one of the main goals that many officials are striving to achieve, and BIM 4D and 5D technologies have played a major role in achieving these goals.
