The history of railway standardization offers a compelling parallel to the modern construction industry's pursuit of efficiency and collaboration. Just as the standardization of rail gauges revolutionized the railway system, the establishment of open data standards, particularly in Building Information Modeling (BIM), is pivotal in the construction sector. This article explores the latest developments in BIM standards and draws connections between the historical lessons of rail gauge standardization and the contemporary challenges and opportunities in construction.
The Railway Standardization: A Historical Perspective
Before the Civil War: Engineers building railroad systems before the Civil War faced challenges due to the lack of standardized rail gauges. The absence of uniformity in the distance between the center lines of the rails led to inefficiencies and operational hurdles.
Solutions and Challenges: Various solutions were proposed to address the lack of standardization in the railway system. The journey towards standardization was fraught with challenges but ultimately led to a more efficient and interconnected railway network.
Parallels with Construction Industry: The key to efficient design and construction today echoes the lessons learned from the standardization of rail gauges. Establishing open data standards, akin to standardizing rail gauges, enables seamless sharing of information, fostering collaboration, innovation, and efficiency.
The New BIM Standard: Version Four
Final Stages and Adoption
The National BIM Standard-United States® (NBIMS-US™) Version 4 has been meticulously developed over three years and is now in its final stages. It opened for public comment on May 3, 2023, and will be unveiled at Building Innovation 2023 in September. This version emphasizes BIM execution planning and includes Project BIM requirements, focusing on making it easy for owners to adopt BIM and realize its benefits.
BIM Execution Planning
The upcoming release of version four of the national BIM standard includes improved templates and tools for BIM execution planning. This aspect has been widely adopted in the industry but not holistically. The integration of BIM execution planning into the national BIM standard aims to fill this gap, providing professionals with the necessary resources to ensure that BIM is utilized to its fullest potential across various stages of a construction project.
Project BIM Requirements
The national BIM standard now includes a section on Project BIM requirements aimed at helping owners navigate the different stages and pieces of BIM. This includes a default template for those who may not know what to ask for or understand all the details. The focus of the BIM program is to make it easy for owners, particularly those with multiple campuses and buildings, to adopt BIM and realize its benefits, as they are at the head of the supply chain and carry the most risk.
Emphasizing Open Data Standards
The BIM program emphasizes open data standards, allowing stakeholders to choose their own software tools. This ensures that information can be passed through the project lifecycle without loss of fidelity or corruption, making things more efficient for owners. Open data standards are crucial in the construction industry to eliminate inefficiencies and waste, allowing for the exchange and use of information across different applications, and ultimately advancing the industry as a whole.
Metrics for Success and Future Considerations
The project team focused on defining clear metrics for success to drive the adoption of BIM. People are more likely to embrace change when they see potential benefits and can measure improvements in terms of their business's bottom line, return on investment, and productivity. The future of the construction industry relies on the workforce embracing data and considering solutions such as automation and robotics, especially in light of the projected massive reduction in the workforce in the next 10 years.
Benefits for Owners
Owners can benefit from using BIM by being able to build more efficiently, allocate funding from Opex to Capex, and make informed decisions that impact the entire lifecycle of a building, while ensuring data security and access to the right information. Good data and standards are essential for the successful implementation of BIM, serving as the foundation for productivity, accurate location placement, and automation.
NIBS and the Challenge of Digital Twins
NIBS, a non-profit organization, aims to improve the entire construction industry by convening experts from various stakeholder groups to address issues and find solutions. One such challenge is the lack of standards for digital twins in the built environment, which needs to be addressed to effectively utilize models, data, and AI in the construction industry.
The National BIM Standard-US Version 4 represents a significant step forward in the standardization of BIM practices. By addressing the industry's challenges and focusing on key areas such as BIM execution planning, Project BIM requirements, open data standards, and metrics for success, the standard aims to streamline the implementation of BIM and foster collaboration and efficiency within the construction industry. Its alignment with the needs of owners and the broader industry trends further enhances its relevance and applicability, making it a vital tool for the future of construction and building management.
