Construction Documentation deals with preparing and controlling construction drawings and documenting the process of construction. Controlling the construction drawings attached to tender documents is a part of our service; On the other hand, most of construction projects in Iran and other developing countries are not well documented leading to project failure or conflicts between clients and contractors. Construction Process Documentation (CPDOC) is a service given by Construction Strategy using BIM and other documentation techniques in order for decreasing the potential legal conflicts and helping better maintaining the construction projects during their lifecycle. Building Information Modeling BIM as an intelligent model–based design process adds value across the entire lifecycle of building and infrastructure projects. BIM helps architecture, engineering, and construction (AEC) service providers apply the same approach to building and infrastructure projects.
