THE BIM STANDARD – SHORT PRESENTATION
The BIM (Building Information Modelling) standard is the solution identified by modern civilization, after years of research, to make construction work more efficient, both in terms of implementation timelines and allocated budgets, and CO2 emissions reduction, at all stages of the lifecycle of these constructions, namely design, documentation, construction, operation and maintenance, as well as demolition.
Collaboration between participants in the implementation of construction projects is essential for the efficient delivery of facilities and the sustainable development of modern society. Organizations involved in the project need to work increasingly in new collaborative environments to achieve higher quality standards and greater re-use of existing knowledge and experience.
The major advantage of working in a collaborative data environment (CDE), both in the design and execution phase of a construction, and in the exploitation and maintenance phase, is the ability to communicate, reuse and share data effective, without loss, contradiction or misinterpretations. Every year, across the European Union, considerable resources are spent on correcting non-standardized data used, to train and form new personnel, able to work with the latest techniques in data creation, to coordinate subcontractors teams efforts and to resolve data reproduction issues.
The BIM standard establishes the methodology for managing production, distribution and quality of construction information, including that generated by CAD systems, using a disciplined collaborative process and a specific naming policy.
The standard is applicable to all parties involved in the preparation and use of information necessary for design, construction, operation and deconstruction, throughout the life cycle of the project and the supply chain. The principles of information sharing and common modeling apply equally to both infrastructure and civil engineering projects.
In the spirit of the requirements of this standard, there was also a substandard, called IFC (Industry Foundation Class), which is a guide for all CAD and CAM software developers in order to make their applications compatible with the BIM standard and to support its implementation by facilitating the data sharing of the digital building model between the different software applications that compete with its design, execution and exploitation.
During the exploitation phase of a building, the use of the BIM standard will allow the planning and management of maintenance work, both for architectural and structural elements, and for all installations serving the building.
The process of testing the implementation of BIM standard in construction began a decade ago in the United States, followed shortly by the UK and the Scandinavian countries. Due to the results, which lead to savings of 15-20% of the investment budgets, it was eventually adopted by these countries for all construction works financed from public money.
Adoption of the BIM standard has continued in other countries like France, Germany, Belgium, the Netherlands, Spain, Italy, the Czech Republic, Estonia, Portugal, Poland, Slovakia, and from 2017, through the collaboration of 21 European countries, become the European Union’s sustainable development strategy and the future requirement for the financing of public works projects by the Community budget.
In accordance with the public procurement regulations included in the 2014 legislative package of the European Parliament, the Directive 2014/24/EU Article 22 (4) allows contracting authorities to require the use of building information electronic modelling(BIM) tools.
At present, the BIM standard has diversified in several directions (design and execution, operation and maintenance, respectively building security) becoming a suite of standards that continue to harmonize and integrate with other standards such as ISO-TC59, CEN- TC442, or the Geographic Information System (GIS).
METROUL S.A. POLICY REGARDING THE BIM STANDARD TECHNOLOGIES
The emergence in the UK of BS 1192: 2007 standard, more than 10 years ago, immediately attracted the attention of management and specialists from METROUL S.A. on the major benefits of the BIM standard, so that the company underwent an extensive process of restructuring its design processes through partnerships with Autodesk, Nemetschek, Graitec and Stabiplan, which aimed to acquire software licenses that are compatible with the new standard, staff training for coordinated and collaborative work, and the development of working procedures specific to this standard.
Through its active participation, from 2017, to the Technical Committee CT-335 “BIM and the sustainability of the built environment”, within the Association for Standardization in Romania, METROUL S.A. is a fervent supporter of the adoption at national level of European BIM standards and legislative amendments necessary for their use in all public works as a guarantee of increasing their quality and sustainability, reducing CO2 emissions in the atmosphere as well as reducing costs maintenance and exploitation.
From the desire to create a framework for dialogue and professional development, according to the principles of the BIM standard, of architects and design engineers in Romania, as well as to represent and protect their professional interests, both at national and international level, by creating in an organizational framework, METROUL S.A. became involved with other companies in the creation in 2018 of the “Professional Association of Specialists in BIM – APS BIM”.
