Abstract: Purpose: The purpose of this study was to increase the efficiency of the planning stages in the building industry. The goal was to produce valuable information that will be useful in the future development of Swedish national BIM guidelines. Method: The study has been conducted by following the principles of content analysis. “Content analysis is a research method that uses a set of procedures to make valid inferences from text”. By searching for and analysing the content of national BIM guidelines, valuable information for future development of Swedish national BIM guidelines would be produced. The BIM guidelines had to fulfil two criteria in order to qualify for the study: Be a national BIM guideline. Have a version in English. Once selected, the guidelines were analysed using 11 topics, namely BIM execution plan, Level of Development, Format standards and their application – interoperability, accountability, filing, archiving, modes of collaboration, operations and maintenance, simulations, pre-qualifications, BIM functions through project phases. These were chosen based on works by R. Sacks, Gurevich, & Shrestha and Hooper. Findings: Out of the 81 BIM guidelines listed in the BIM guides project by BuildingSMART, 10 national BIM guidelines from 10 different countries were chosen for further study. NATSPEC from Australia, Belgian guide for the construction industry, CanBIM from Canada, COBIM from Finland, HKIBIM BIM project specification from Hong Kong, New Zealand BIM handbook, Statsbygg BIM manual from Norway, Singapore BIM guide, Level 2 PAS from the UK and NBIMS from the USA. All topics have a high level of inclusion, pointing to that the topics from Hooper and Sacks are relevant on a global scale. Pre-qualifications scored the lowest, and BIM functions through project phases scored the highest. Implications: Cover all 11 topics reviewed in this study. Avoid strict protocols with excessive level of detail, but rather formulate guidelines as frameworks, thus making them user-friendly and usable. Formulate guidelines so details may easily and logically be worked out in a BIM execution plan. Make a plan to keep the documents up to date. Limitations: This study only includes national BIM guidelines with English versions available. It has solely been conducted by document analysis and does therefore not provide much information on what current users of national BIM guidelines think of the guidelines reviewed, apart from what is mentioned from Hooper’s work. The score of each guideline indicate how much information it contains, and a high score may therefore not necessarily indicate it is the most user-friendly and readable guideline. Keywords: BIM guidelines, national BIM guidelines, BIM implementation
