Further introduction of information modelling technologies in the course of implementation of investment projects in the field of housing construction

Abstract

Introduction. Modern housing construction requires (1) a single digital platform that has a common data environment, (2) workflow digitization, involving all stakeholders of an investment and construction project. The authors demonstrate that the implementation of this approach will ensure not only the monitoring and control of financial values of construction, including disbursement schedules and a single consolidated database for all documents on each construction project showing access rights to information, but it will also ensure the integrity and reliability of information required for the implementation of day-to-day urban planning activities, as well as quick and flexible integration with state information systems.
 
 Materials and methods. Optimization methods were used to find rational engineering and economic solutions for investment and residential housing construction projects. Multivariance was employed to substantiate the applicability of solutions in the process of introducing digital BIM technologies aimed at identifying the most effective project options.
 
 Results. The main result of the presented research is the application of the G. Taguchi loss function to devise a model for assessing the economic efficiency of options of an investment and construction project, that take into account the total loss of economic efficiency in the course of implementing various technologies of an investment and housing construction project.
 
 Conclusions. The results enable the co-authors to use the proposed model to evaluate the economic efficiency and to identify (1) options of an investment and housing construction project, (2) the range of acceptable options of project implementation that are economically feasible, as well as (3) ranges of unacceptable project implementation options that are “too bad for the consumer” and “too expensive for the producer”; (4) the best project option; (5) the way to improve the generalized algorithm of BIM technology application in practical housing construction.
