Modern construction projects are characterised by complex multifunctional relationships that require processing a large amount of information. The main task of innovative development of construction development is to create competitive advantages in the strategic perspective, which form a safe and comfortable environment for human life that meets high international quality standards, ensuring sustainable socio-economic development of the country's construction industry. Integrated Project Delivery (IPD) is a completely new idea based on Building Information Modelling (BIM) technology. The main idea is to work closely with the investor, designer and executors of a construction project. Achievement of competitive advantages should be based on innovative re-equipment of the construction industry, development of innovative competences, engineering schemes for life cycle management of construction projects, application of information technologies to increase productivity, reduce energy intensity, material consumption and cost of construction products. The article analyses the benefits of using information modelling and the integrated project implementation method in construction. A mathematical model for choosing the optimal network organisational structure of a project is developed. The main factors affecting the synergistic effect of the construction project implementation (costs of making changes to the project, increasing the implementation time, transaction and operating costs) are identified. An economic and mathematical model for assessing the synergistic effect of the joint implementation of integrated construction project implementation and information modelling has been built and tested in practice. A simulation model has been developed for a comprehensive study and optimisation of the communication network of participants in the implementation of a construction project. The results obtained will allow the top management of contractors to effectively monitor, structure and manoeuvre assets in their operations, substantiate the economic strategy and parameters of the production and business portfolio of construction companies.
