1) Eliminations of errors & omissions lead to a reduction of rework, construction cost & overall project duration. So the BIM engagement improves the project delivery cycle.
2)Leveraging BIM to improve collaborations among team members including owners & design firms which leads to greater integration among all team members which considered one of the most important trends from model-oriented projects.
3) Enhancing business development through not only delighting their clients & maintaining long term relationships with them but also enabling the attraction of new ones
4) Improving safety & faster cycle times for workflows and accelerating client and regulatory approvals.
Hence shortly we can classify BIM benefits into three types:
Internal benefits
Accrue directly to the contractors who use BIM
Project benefits
Which means improving the highest level of quality for the project delivered at an extremely lower cost?
Process benefits
Enhancing project workflow and processes among all parties
