This blog aims to detail COBie, the challenges in its implementation, its benefits, and the future of asset management.

Understanding COBie Data

COBie, a vital tool for construction and facility management, allows for a seamless transition from traditional building information documents to a highly collaborative computation-aided environment. Originally developed by multiple US public agencies, it has become the standardized data exchange format to improve the handover process from the construction phase to building or facility owner-operators.

What Is COBie?

COBie stands for Construction Operations Building Information Exchange. It is an internationally standardized non-proprietary data format. It is used for publishing a subset of building information models specifically focused on delivering asset data. Essentially, COBie serves as a framework for organizing and delivering crucial asset management data in building projects. However, it is important to note that COBie data differs from geometric information in construction projects.

COBie follows a vastly different approach from the conventional, manual documentation processes. The development and implementation of the COBie data format has successfully improved the handover process for AECO professionals, from construction professionals to facility or building owner-operators.

Adding value to project lifecycles, COBie deliverables specify the required data fields and tables necessary for project handovers. Moreover, these COBie specifications underscore the importance of detailed documentation for updating and managing assets through each stage of construction. For example, post-completion, this standardized format for data-sharing translates effectively into successful facility management processes with accurate and detailed information.

Brief History of COBie

In 2005, the National Aeronautics & Space Administration (NASA) and the White House Office of Science & Technology provided a grant to the United States Army Corps of Engineers to develop COBie. At their construction engineering research laboratory facility, William East from the US Army Corps then ideated and created COBie, a set of international standards for data and classification.

The initial idea of COBie was to provide necessary information to building owners, facility managers, and personnel in charge of operations and overall maintenance in the US. The pilot version developed in 2009 was then updated and gained recognition from the National Institute of Building Sciences in 2011. Over time, it transcended the borders and became the acceptable format of construction data consolidation globally.

For example, in 2019, the UK National Annex mandated that all non-geometric information exchange in open-data formats in building and construction projects must be structured using the COBie standard.
