The need for BIM Standards in digital construction

Updated: May 14

The implementation of Building Information Modelling (BIM) in construction projects involves the digital representation of the physical and functional characteristics of the components that constitute a construction project. The produced BIM digital model constitutes a reliable basis for decision-making throughout the life of the project and features not only great benefits associated with reduced delivery time, but also, improved co-operation between sectors and lower construction cost of projects.

The use of BIM is in rapid growth in the largest construction markets and many countries worldwide have already institutionalized through the mandatory implementation in all public works. Although the USA was the first country to adopt BIM, the highest success rates of BIM are recorded in countries where BIM is mandated, such as the United Kingdom, based on specific standards and procedures.

A second factor that prevents BIM from spreading is the confusion caused by the wide range of BIM software and the interoperability they have with each other; the transfer of data from one software to another.

Users must be able to extract models from one software to another regardless of the which program they use. The IFC standard from Building Smart International has been created to solve this issue and is subject to continuous improvement.

But why are standards in the BIM process needed? BIM is a procedure and procedures need standards and guidelines to be effective and accurate.

Standards exist in many sectors of our lives and improve the quality of the various daily use items, such as standards already applied to food and electricity, but also to products of the construction itself. such as windows, materials, etc. Overall, the manufacturing industry and sector collaboration is no exception, and standards can contribute to producing optimum cooperative processes and deliverables for building projects through BIM.

In the United Kingdom, national BIM standards have been developed due to the relevant mandate for adopting the BIM. The UK BIM standards refer in detail to the BIM Maturity and consist of a large number of documents which define in a clear way procedures, roles, deliverables, levels, and so on. Other countries such as Finland, Norway and Singapore also have national BIM standards and most countries worldwide plan to follow suit.

In countries where BIM has not been institutionalised and there is no such provision, several private and public bodies are developing initiatives with their own standards for the use of BIM. This, of course, makes it difficult to adopt BIM in the industry because each engineer, architect and contractor needs to learn many unique BIM standards for each project involved.

In addition, globalization has affected the construction industry and there has been a significant increase in international projects and collaborations. The fact that each country has its own rules and regulations impedes an agreement on European or global BIM standards. The best known BIM standards currently implemented are PAS 1192-2, COBie, NBS National BIM Object Standard and IFC.

In an effort to form a common international standard base for the implementation of the BIM, in December 2018, the new ISO 19650 was published. ISO 19650 is based on the proven English standard BS 1192 and promises to bridge the gap between the different industry BIM standards. Its implementation and, to what extent will affect the implementation of BIM at international level is still ongoing.

BIM is the future of the construction industry, and the sooner the industry adopts the BIM and all related standards, the sooner it will enjoy the benefits of BIM in relation to the cost and timing of the project delivery. The creation and adoption of BIM specifications and protocols can lead to a consistent and effective method of data exchange with great benefits for construction projects.

BIM certified online training, in line with ISO 19650

BIM training by BIM Design Hub introduces you to the concepts and principles of Building Information Modelling, BIM, in line with ISO 19650 and provides sufficient skills and knowledge of the BIM process, standards and guidelines that support the digitalization of the construction industry.

BIM training is delivered through an online educational platform with a rich learning environment. As part of our training, students are entitled to the ISO 19650-1 and ISO 19650-2 standards, and a discount to purchase the British standards from BSI, such as the BS EN ISO 19650-2, the PD 19650-0:2019, ISO 19650-3, ISO 19650-5 and BS EN 17412:1-2020.
