We see BIM as a part of our natural progression towards better engineering, construction, and increasing value for our clients. By approaching BIM as “business as usual” we ensure the highest quality design and construction are delivered with a lifespan that endures the life of the asset. The introduction of BIM into infrastructure engineering is something we embrace and continue to develop. We are actively using BIM methodologies to deliver the collaborative and coordinated design and construction on a number of projects ranging from the Building of Brazil street in Tehran and Bagratashen joint border Bridge between Armenia and Georgia. Tunnel Sadd Ariana has been consistently working in live collaborative sharing environments for many years creating efficient and highly customized CAD and design systems for multi-discipline and multi-site operations. We utilize the same approach in BIM. Our vision and methodologies in developing and managing BIM move to a 4D and 5D process for Monitoring and Controlling our projects in our project management methodology.
