New principles for data exchange in the construction process
The SIA 451 standard, an indispensable tool for the construction and planning industry, has undergone a comprehensive revision. With the new title "Provision and utilisation of data in the construction process", it has been adapted to modern requirements and remains a central basis for data exchange in the construction industry. The aim is to further optimise the flow of information between all parties involved and make it future-proof.
For over three decades, SIA 451 has formed the basis for standardised data exchange in the construction industry. Originally conceived as a guideline for bills of quantities, it defined how data fields should be structured and exchanged as early as 1992. Supplemented by modern requirements, such as the integration of images and memos, the standard has continuously adapted to the needs of the industry. Nevertheless, a fundamental revision was long overdue.
New content and objectives of the revision
The revised SIA 451 not only defines the processes and terms of information and data exchange, but also sets clear requirements for delivery objects, IT infrastructures and quality assurance. The introduction of a standardised information management process regulates the following aspects:
Clear definition of interfaces and data structures
Quality assurance:
Standards for the testing and certification of software solutions.
IT infrastructure:
Requirements for technology and expertise of the players.
These innovations ensure that the standard will continue to serve as the basis for advanced solutions and standards in the construction industry in the future.
Relevance for construction practice
The importance of SIA 451 for the construction process can hardly be overestimated. It is not only the basis for numerous software solutions, but also an essential component of communication between all stakeholders – from planning and procurement to the operation and maintenance of buildings. By promoting open standards, it creates transparency and access for all market participants. This strengthens collaboration and enables technological innovations to be integrated efficiently.
A standard for the future
The revision of SIA 451 represents a decisive step towards the digital transformation of the construction and planning industry. The revised content sets new standards for data exchange and creates a solid basis for future developments. SIA 451 thus remains an indispensable tool for everyone working in the construction industry.
