The publication of the National BIM Standard (NBIMS) at the end of 2007 after two years of work by the most highly diverse team ever assembled by the National Institute of Building Sciences brought a symbolic shift in the architecture, engineering, construction, and facility ownership (AECO) community. However, what impact did it have on the industry? This chapter looks at the strengths, weaknesses, opportunities, and impact of the NBIMS into 2009 and beyond. Specifically, this chapter will delve into some of the strengths of the NBIMS, such as promulgating a standardized approach for documenting information exchanges between stakeholders, and applying the NBIMS Interactive Capability Maturity Model (I-CMM) to evaluate a project or portfolio for BIM maturity. Opportunities exist in the areas of sustainability, modularity, and fabrication, as demonstrated in several industry projects to date. Weaknesses of the NBIMS are that it is not directly applicable yet at the technical level such as the National CAD Standard (NCS). Along with the NCS, the NBIMS and their umbrella parent organization, the Facility Information Council of the National Institute of Building Sciences are gradually being absorbed into the buildingSMART Alliance. Lastly, the primary impact of the NBIMS will be felt in terms of current and future projects promoting interoperable information exchange for specific stakeholders. These include multiple applications of interoperable-IFC-based approaches.
