Design of a corporate information system for construction project management with integration of calendar planning for procurement costs and as-built documentation

Abstract

The article proposes architectural and methodological principles for designing a corporate information system for construction project management, oriented towards end-to-end connectivity of calendar planning, procurement, cost control, and as-built documentation formation in a unified data environment. It is shown that a characteristic cause of schedule disruptions and budget overruns is the temporal asynchrony of information between subsystems, leading to reactive management and error accumulation during manual exchange and duplicate data entry. For quantitative diagnostics, an information latency indicator is introduced, interpreted as the delay between an on-site event and its reflection in the decision-making circuit; a nonlinear improvement in schedule stability is demonstrated with deepening integration up to real-time transactions, when the average deviation from directive deadlines decreases to 2.15 days, and the response time to a supply disruption—to 2.44 hours. The necessity of using end-to-end resource identifiers and a single reference book of works and costs (WBS/CBS) is justified, ensuring comparability of estimate, procurement, and accounting data and transition from “pot” accounting to elemental accounting, where the root-mean-square budget deviation decreases to 1.89%, and the cash plan error—to 2.11%. The integration of as-built documentation with actual work completion and material write-offs is considered in detail: automated generation and validation of attributes reduces labor costs for routine operations by more than 20 times and lowers the frequency of returns for revision, while preserving the “bottleneck” in external signing. Requirements for software implementation (microservices, offline mode for mobile clients, replication, versioning management of legally significant documents) and the potential of predictive analytics with accumulated linked data, as well as limitations due to the heterogeneity of electronic document management enforcement practices, are noted.
