A practical BIM framework was developed for coordinating the MEP layout.
Four types of MEP coordination were proposed to assure constructability.
71% of errors were found in step 3 while 20% in step 2 and 9% in step 4.
Only 22% clashes were effective when using BIM for automatic clash detection.
Cable tray contributed 61% to total saving, while duct was 23% and pipe was 16%.
