In 2002, PMI began publishing industry-specific application-area extensions to A Guide to the Project Management Body of Knowledge (PMBOK® Guide). The Construction Extension to the PMBOK® Guide was first published in 2003 and has been updated with each subsequent edition of the PMBOK® Guide.
The industry extensions were updated periodically to maintain consistency with each new version of the PMBOK® Guide. This edition of the Construction Extension eliminates specific processes and references that become obsolete with each new edition of the PMBOK® Guide. This new format, generally described as principle-based rather than process-based, ensures the industry-specific extensions remain aligned with subsequent editions of the PMBOK®
