First of all, we must say that BIM is not a software, BIM (Building Information Modeling) is a methodology widely adopted in the construction industry to optimize planning, design and project management, unlike Revit, which is one of the most used software under the BIM methodology.
Since December 17, 2018, due to the European Directive 2014/24/EU on public procurement, the use of BIM became mandatory for Public Building Tenders. However, in GESAB the Public Sector Contracts Law 9/2017 applies, which allows, but does not oblige, public organizations to require the use of BIM in public tenders in three different ways: as a requirement of technical solvency, as a criterion of evaluation of offers or as an extraordinary additional benefit.
For these reasons, BIM is also being increasingly used in other industries and sectors related to the specific use and equipment of each building. In this article, we will explore the benefits of implementing the BIM methodology in the project design and execution processes.
So, what is BIM?
BIM is a digital process that involves the creation of a 3D model that includes data on the components, systems, materials and any other relevant information of the prototype that can be used for various purposes, such as cost estimation, programming and control of construction, quality control and maintenance. This BIM methodology is applied both in the design of spaces and definition of finishing materials and in the design of facilities and specific equipment, and the scope of the information can be the following:
• 3D. Model oriented towards the geometric representation of the project, from which multiple perspectives can be obtained.
• 4D. Time planning is added, allowing the classification by phases of the model elements and the simulation of execution times.
• 5D. Cost control and expense estimation extracted from the model, from initial estimates to precise measurements with an advanced model.
• 6D. This dimension allows an energy study of the model to be carried out, to seek energy savings in future construction.
• 7D. Once the building has been delivered, this dimension allows for logistical and operational control of the project, as well as maintenance of the useful life, achieving better control of inspections, repairs, maintenance, etc.
Benefits of using the BIM methodology
As we said at the beginning, the implementation of the BIM methodology in the company can be beneficial from several perspectives:
• Improved design process: The BIM methodology can improve the design process from the initial phases of a project by creating a 3D model that allows the product to be visualized more accurately and changes to be made more easily. It also makes it easy to test different finishes, materials and configurations to find the most efficient and effective design.
• Better quality control: It can be used to improve quality control in the manufacturing phase, since through the 3D model it can be verified that they meet the required specifications, such as dimensions, weight and functionality in addition to simulating the installation and operation within the overall project, ensuring that it works as planned.
• More accurate cost estimation: It can be used to create a more accurate bill of materials (BOM) from the initial stages of the project, reducing the probability of errors and omissions that generate cost overruns. Likewise, taking advantage of the synergies between Revit and measurement and budgeting programs such as Presto, structured measurements can be extracted from the model in the necessary way to obtain the complete budget. Traceability allows users to select any element or part of the budget in the model or locate each element of the model in the budget; elements can be linked to work units to obtain assembly codes, texts, prices and breakdowns from a price table in the object itself or, later, in the estimate. The interaction between the model and the budget can be bidirectional, allowing the values of any parameter to be read and written to or from Presto, and can be modified massively, if it is more convenient.
• Construction Control: Within the 5D BIM phase (planning and costs), there is the option to carry out measurements, budgets, certifications, specifications, as well as the use and maintenance manual of a building and its facilities.
• Improved communication and collaboration: The BIM methodology and the use of central models facilitates improving communication and collaboration between the different actors involved in the design process of a project. By using a common platform to share data and families with specific parameters (4D, 5D, 6D) that they can incorporate into their designs, calculations and tenders, it can be ensured that all relevant information is available to everyone involved in the project. In this sense, the existence of family exchange web platforms that provide a Marketplace between architects, engineers, designers and manufacturers becomes important. This can help avoid miscommunications and delays.
• Better customer service: The BIM methodology improves the information provided to end customers, helping in the project and execution phase, as well as in the maintenance of buildings and facilities (5D, 6D, 7D). The company can show the client a 3D model and demonstrate how it will fit into the space, thus providing more accurate and detailed information. It also allows the company to provide more accurate delivery times and cost estimates, which can improve customer satisfaction.
A very important key related to this BIM methodology and that provides an excellent collaborative work tool in the development of design consultancies, which are increasingly common in our work, is the possibility of synchronizing projects carried out in Revit with visualization software in real time that, together with the Unreal Engine interface, allows access to a rapid resource for creating visualizations and immersive experiences that improve the customer experience, speed up the initial phases of project development and facilitate their completion. This will also promote collaboration with models made from other software such as 3DMax and the possibility of sharing materials, finishes, lighting, objects, etc.
The implementation of the BIM methodology has proven to be a valuable resource to optimize the design and management of control centers in various industry sectors. This methodology has transformed the way we conceive and execute projects, allowing for greater efficiency, precision and control at every stage of the process.
