BIM For Cost Performance Optimisation Of Construction Processes

"Our world is changing faster than ever before. Urban areas all over the world have been developed rapidly. Unfortunately construction sector has been rejecting most of the technological opportunities while other industries have undergone significant changes over the last years due to some process and product innovations. The sector has still an intractable productivity problem. However, construction is the world’s largest industry in terms of resource (including energy) usage and waste generation. Improving whole-life cycle resource efficiency and environmental impacts are considered the main challenges of the construction industry in the European Union. Such improvement can be reached thanks to digitalization, advancement of computational tools, brand new construction techniques and methods as well as innovative technologies. Incidentally, companies can boost productivity as well. To make cost performance more efficient, planners/designers should explore more construction/design alternatives and - as a result - make more accurate decisions. High complexity of the construction projects reduces a simplicity of setting up a reliable construction model ready to multi-objective optimisation. Building Information Modelling (BIM) is considered as the innovation that allows for the consistent management of information in the construction projects. This tool turns out to be useful in managing the process of building construction in the whole-life cycle perspective. Additionally, people, standards, processes and the technology form the integral parts of BIM. It is inevitable that construction companies would customise BIM gradually and have to refine and attune the method with increasing know-how."
