11 the contractual regulation of investment and construction processes. There is a need for contract structures that ensure shared responsibility, the distribution of risks and benefits, and the early involvement of all key participants in decision-making based on a unified BIM information model. BIM technologies enable the creation of a digital information model of a construction project, which is used by all stakeholders throughout the project’s entire lifecycle–from concept to operation. Its implementation objectively leads to changes in contractual obligations, as the very logic of decision coordination, information management, distribution of responsibility, and cost control changes [1]. The innovative nature of the BIM approach may be accompanied by complications in the relationships between participants due to the need to redistribute authority, new requirements for data transparency, and shared use of the model; however, ultimately, it is capable of significantly increasing the level of trust and balancing the economic interests of all parties. In this context, it is extremely important to implement contractual models that integrate legal, organizational, and economic mechanisms for the joint implementation of the project. One of the most effective BIM models for organizing investment and construction projects is the concept of Integrated Project Delivery. IPD is viewed as an integrated approach to project implementation that involves the early engagement of key stakeholders, the joint establishment of goals and success metrics, the collective sharing of risks and outcomes, as well as the use of open technologies and a unified information environment [2]. Key Features of IPD: 1. Mutual benefit for participants. Under IPD, financial outcomes are tied to the achievement of shared project goals. IPD contracts treat cost as a key economic criterion for investment, which is established and specified as early as the project conceptualization phase. Cost is aligned with market indicators and investors’ capabilities, and is subsequently controlled throughout the entire implementation cycle based on BIM model data and transparent management accounting procedures [3].
