BIM building information modeling is actively used by many construction companies as an effective tool for coordination, visualization, communication, construction site management, prefabrication and marketing. It is possible to create a virtual model of a building and track all the processes related with construction by the help of bim building information modeling . Team members, planning engineers, architects, project coordinators, project managers and stakeholders can easily understand the project to be constructed. In this article we will review the benefits of bim building information modeling .
BIM Building Information Modeling
According to the US National Building Information Model Standard Project Committee Building Information Modeling (BIM) is a digital representation of physical and functional characteristics of a facility. A BIM is a shared knowledge resource for information about a facility forming a reliable basis for decisions during its life cycle; defined as existing from earliest conception to demolition .
BIM Building Information Modeling Benefits
BIM Building Information Modeling is a 3 dimentional model based process. Traditional building designs consist of two-dimensional drawings. The building information modeling (BIM) boosts this beyond 3D by adding the width, height and depth dimentions to the plans with time as the fourth dimension and cost as the fifth dimention.
BIM illustrates the entire building life cycle from inception and design to demolition.
Collaboration: Construction projects are short-term and multi-disciplinary operations and face with many problems due to lack of collaboration among project stakeholders. A single BIM model used for both analysis and documentation phases allows the owner, designer, contractor and sub-contractors to work on the same platform which helps to address communication problems. BIM Building Information Modeling allows to combine all of a project’s documents into a single view. Increased collaboration and coordination results in project time and cost savings.
Construction sequencing: Building a structure involves different types of resources. A lot of time and effort is spent for this purpose. A building information model can be effectively used to coordinate material ordering, fabrication, and delivery schedules for all building components . It gives the opportunity to evaluate and decide the sequence of work among various construction scenarios. BIM simulations are also for field teams to understand the sequence of works and work accordingly.
Visualization and Simulation: The digital representation of the project is vital in terms of explaining to the owner what he/she invests in, how the project looks like rather than preparing the physical architectural models. It also helps to make quick decisions for evaluating different design options and/or solving problems encountered in the design. Another point is that BIM provides numerous simulation tools that allow designers to visualize such things as the sunlight during different seasons. Moreover, the BIM model helps the cost estimators to virtually construct the project in details during bidding phase. On top of that, visualization is utilized as an effective marketing tool.
Clash detection: The structural, architectural, mechanical, electrical, and plumbing (MEP) projects are incorporated into one shared model. The clashes are identified in the early stages of the project and solved accordingly before actual construction starts. By doing so, construction teams can work more effectively and unexpected cost increase and time delays can be mitigated.
Automated material quantity takeoff: Cost estimation is based on the quantity of the work items in the project. In traditional methods, all quantities are extracted from 2D drawings. It is a time-consuming process. Since BIM model encompasses properties of the elements, the BOQ can be extracted from BIM model. This method saves the time that quantity surveyors spent for quantity takeoff. By doing so, cost estimators will have more time to focus on cost analysis. It is important to keep in mind that the quality of information in the BIM model is vital. İf the quality of information embedded in 3D BIM is not improved, QS would not benefit from the potential advantage that BIM can offer because QSs would need to spend time checking the accuracy of BIM prior to quantity extraction as well as sorting and splitting items for costing purposes .
Effective Cost estimating: Cost is one of the main issues in the construction sector .By the help of cost estimating feature of BIM, it easy to extract the quantity of materials from the model. The model automatically calculates the quantities in the case of changes that helps to save both money and time.
Supports Energy Efficiency: Traditional design and construction processes does not provide adequate environmental analyses. BIM allows to make early-stage environmental analyses that helps you to explore aspects like building orientation, energy use and daylight.
BIM is a relatively new technology in the construction industry. The future of the construction industry will rely on digital systems. BIM Building Information Modeling helps to to decrease project cost, increase productivity and quality, and reduce project delivery time. BIM provides a virtual model of the building to be constructed. The model can be used to demonstrate the entire building life cycle .Sharing and cooperation are essentials throughout the architecture, engineering, and construction (AEC) industry.
