Often construction project risks are unseen and unpredictable, with disintegration being the main culprit, hindering the smooth flow of communication among stakeholders involved. Lack of communication triggers internal risks, too. All of this leads to misinformation, misunderstandings and it ends up creating mistrust and poor relationships among the design and construction stakeholders such as architects, engineers, contractors and fabricators. However, the challenges don’t end here. Internal risk is further classified from the internal project management team, designers, and owners. Risk at design might originate from: Incomplete design information: The designers often have to rush to complete the design phase. It is likely to happen that it does not meet the set needs and may also be defective in terms of errors. Drawings: The quality parameters and the specification produced by the design professionals. Occupational risk: Injury, possibly fatal, to a worker because of behavior, methodologies or technologies used weather or a third party. Design changesthat occur during construction phases are another reason to internal risk. Ideally, Building Information Modeling (BIM) is an information rich object-oriented, intelligent, and parametric digital 3D geometry of the facility, from which interpretations and documents suitable to several users’ needs can be extracted and evaluated. Site engineers and chief contractors can use it to generate information as opined that can be used to make informed decision and improved the process of delivering the facility with minor risk. How BIM mitigates risk in construction projects Contractors find it the most difficult task to plan and design accurately, aligning the design with the determined project viability with the constantly shrinking financial budgets. However, BIM can aid in this process. For instance, visualization of the initial design by 3D/4D models can assist engineers in modifying the model in parametric way to meet the requirements. Virtual Walkthroughs work great in such scenarios as it simplifies the understanding. IFC data format could further strengthen the interoperability in BIM and aid in reducing possibility of errors. Benefits through 3D, 4D and 5D BIM modeling All of the characteristics of 3D BIM can help the design stakeholders collaborate better at early stages and include the changes early. As a result, a significant chunk of rework is avoided and can save the site engineers from risking the already finished construction. Secondly,4D construction simulationand construction sequencing videos help the planning of logistics on site and setup the workflows in a logical and efficient manner ensuring Integrated Project Delivery (IPD). The main advantage of BIM is it has ability to decrease error made in design stage by mechanism of clash detection though various visualization techniques. As BIM grows into more data rich model, it can help save cost by reducing risks in time and errors. 5D BIM cost estimationapplications can help to build the virtual project and simulate the construction process, cash flow and scheduling. Hence clients, designers, contractors and risk experts can identify risks at an initial stage and put forward any required mitigation procedures in advance. Above all, 5D BIM helps contractor in preparing BIM construction documentation and accurate estimation for the project for tender bidding. BIM for Environment Often overlooked, construction harms the environment. The air, water, and soil are significantly damaged because of the construction activities in varying amount depending upon the nature of the construction project and location. But BIM helps in practicing lean construction methods there by reducing waste. Additionally, BIM helps in designing buildings that can make the maximum use of natural resources and reduces the energy consumption through the compressors, generators, and pumps used to run the facility. Sustainable buildings designed with the help of BIM have become a trend owing to the movements to reduce the carbon footprints in environment. BIM for Safety As mentioned earlier, different views and misinterpretations are potential factors creating risk. What you need is a flawless communication and collaboration for successful risk management. For example, BIM can be utilized through organizational limits, which consist of interdisciplinary as well as cross-disciplinary coordination. Additionally, BIM is vital for vertical incorporation of data exchange within one design and construction discipline such as concrete design, fabrication, and construction to ensure that there is single source of truth for the entire project team. Mitigating risk in projects has played a crucial role in project’s aspects of cost, quality and sustainability. And Building information modeling (BIM) makes construction safer for construction workers, construction firms, professionals involved and leaves carbon footprint to a lesser extent, thereby saving the environment as a whole.
