Green building investment control system based on a three-dimensional parametric model of the green building

Investment in construction projects is a rather complex process. The customer of construction product, as a rule, is also its investor and for him the systematization of information about the construction process is a necessity. Construction investment control (CIC) is an integral part of the building construction process. Such control is a separate service that is necessary for the customer to objectively understand the installed work volumes and forecast deadlines. Completed construction and installation works are confirmed by acts of acceptance of the completed works, which are subsequently the basis for payment for the work done. In this paper, we developed a methodology for managing investments in construction, as well as their control using modern BIM technologies. The effectiveness of using 3D modelling in investment control was demonstrated on the example of a residential complex. In addition, the volume of work obtained from the 3D-model was compared with the volume of work calculated manually. As a result, the exact amount of work and schedules for forecasting investment of funds were obtained.
