Development of a capital expenditure model in the context of construction digitalization

Introduction. The purpose of this research project is to study the development of construction digitalization methods and means. Substantial discrepancies between the state digitalization policy and the practice of mastering digital instruments in the course of construction and investment activities hinder the high-quality implementation of certain tasks. Of particular interest is the problem of calculating capital expenditures at various stages of implementation of an investment project. Materials and methods. Methodological approaches to digitalization problems are based on the pricing subsystem extracted from the information model of a project. This subsystem is used to address the main pricing tasks pursued by the government authorities and construction industry contractors implementing their own digitalization options. Conflicting interests of different participants in construction and investment projects, as well as the variance in the informatisation stra­tegy, implemented at the previous stages, substantially complicate the search for a solution that equally satisfies the state and the business community. Results. The authors have identified the need to devise consistent state-level methodological approaches to developing information modelling architecture, taking into account the current practice of construction cost budgeting in the course of project management. Towards this end, the logical structure of the “Pricing” subsystem was developed using the information modelling technologies. Design companies, technical clients, project managers, and construction contractors must have equal rights to access and handle construction cost data. Conclusions. The authors have found a discrepancy between state approaches to construction project budgeting and cost management practices at the stages of construction project implementation. No large-scale transition to information mode­lling is feasible without the adoption of unified methodological solutions in terms of cost calculations.
