The article is devoted to the development of economic and applied tools for the management of construction enterprises within the framework of the formation and implementation of a stakeholder-oriented management strategy to increase their investment attractiveness, which made it possible to substantiate the directions for increasing the effectiveness of the level of stakeholder interaction based on the methodology for assessing the level of stakeholder relations, the results of economic and mathematical modeling and the proposed analytical diagnostic system of local and integral stakeholder indicators. The existing methods of assessing the effect of the introduction of information modeling and integrated implementation of the project in construction were analyzed. A methodology for integral assessment of the level of stakeholder relations of construction enterprises is proposed based on the application of a complex of analytical subsystems: a) a subsystem for evaluating construction projects as potential components of the economic portfolio of a construction enterprise-stakeholder; b) a subsystem for diagnosing the competitiveness of the project customer as the initiator and leading subject of the construction and investment process; c) a subsystem of ensuring compliance of the characteristics of construction development projects with the leading dominants of the operational system productivity of the enterprise-stakeholder construction;; d) a subsystem of economic monitoring of the growth of the value of qualified assets of the developer company and the growth of its image as a leading stakeholder in the market of commercial housing and infrastructure construction. The improvement of the system of indicators for evaluation and selection of projects for the economic portfolio made it possible to build an effective means of formalized management of the performance of the operating system of the construction stakeholder enterprise as part of the toolkit; through the prism of preventive assessment of the productivity of implementation of operational and production cycles of projects (strategic economic units as part of the economic portfolio of a construction stakeholder enterprise).

The article is devoted to the formation of theoretical and methodological provisions and applied principles ofprocess-oriented development of construction companies aimed at improving the procedural and instrumental basis for makingeconomic and managerial decisions in a dynamic business environment for investment and construction projects. The constructionindustry has a much higher degree of fragmentation of process characteristics compared to other types of activities, which aredetermined by the extremely high level of economic dynamism, where companies are constantly faced with the need to adapt tomarket transformations. functioning, connections and relations between the components of the economic and production system ofthe enterprise as an object of management). Implementation of the process approach allows to systematically combine functionalareas of activity, to build transparent and understandable for employees of the enterprise schemes for the implementation ofmanagement tasks, evaluate and optimize resources. Methodological and applied business tools for the formation of the budget ofthe construction development project were further developed, which provides for phased and multi-criteria formation of budgetsof contractors and the total budget of the development project on a new calculation and analytical basis.

The article provides a theoretical generalization and offers a new solution to the scientific problem, which is to develop theoretical, conceptual and methodological and scientific and practical provisions for the formation and development of structural management of construction companies in modern business macro trends. The transformation of the business environment of modern enterprises has led to the dominance of radically new principles of ensuring their sustainable development and competitiveness in the market. There is a gradual transition from the idea of purely competitive struggle to the formation of stable trusting partnerships between key participants in socio-economic relations. Under such conditions, the concept of building social and labor relations in society is changing, which has now made an evolutionary leap from the stage of declarative social interaction of enterprise management with staff to intersectoral social partnership in the field of intellectual and personnel support of economic entities. Selected methodological and applied basis of the study, based on: modern platforms for construction development, "management by objectives", productive concepts of budgeting and synthesis of applied tools of economic-analytical and economic-diagnostic decision-making tools, which allowed to build an updated system of indicators of the company's operating system -developer through the prism of the implementation of operational and production cycles of investment and construction projects.

The construction industry has a significantly higher degree of fragmentation of process characteristics compared to other types of activity, which are determined by an extremely high level of dynamism of the economic environment, where enterprises are constantly faced with the need to adapt to market transformations, an integral component of which are organizational and structural changes (transformation of the structure, regimes functioning, connections and relations between the components of the economic and production system of the enterprise as an object of management). The formation of development as an innovative investment infrastructure of a construction project has a dual purpose: on the one hand, it acts as an objective indicator of the level of competitiveness of the enterprise, which allows the investor to have a clear idea of the level of investment attractiveness of the enterprise as an object of external investment; on the other hand, as a tool for diagnosing the state of implementation of the investment program and making relevant functional and investment decisions. An innovative process-oriented toolkit for evaluating and selecting options for a portfolio of construction projects is proposed, the content of which is adapted: to the content of the operational activities of the developer as one of the leading subjects of the construction and investment process and to the nature of the structure of the developer company operating in a multi-project business environment as administrator, coordinator and regulator of the processes of initiation, preparation and implementation of construction investment projects. The scientific-methodical and analytical results of the study provide the construction stakeholder enterprise with the proper economic balance of the processes of functioning in the environment of the development project and in the digitally adapted space of formalized strategic coordinates, provide project implementing enterprises with a scientific rationale for the essential growth of adaptogenic characteristics and the choice of an option to substantially improve the state of competitiveness of the enterprise : the results of the work collectively update the scientific and methodological basis of economics and management of construction enterprises.

The scientific and applied task of increasing the accuracy of determining the estimated cost of a construction object (EСCO) requires new methods of solution, especially for construction objects that are planned for inclusion in the investment program. Until now, there is no complete information about the processes of formation of the ECCO and the system of management decisions that ensure planning, regulation and cost control during the implementation of investment programs. What is needed is not just information, but a knowledge base, which, as the analysis showed, is rather characterized by its absence, since the composition of the input data and the requirements for them have not been determined for the justification of the ECCO and its management. To solve this task, it is advisable to create an organizational and economic mechanism for the management of the ECCO, the key blocks of which are the developed economic-mathematical model of the ECCO and the organizational model of the ECCO management in order to provide informational support and interaction of construction stakeholders. Within the framework of the research methodology, the conceptual and methodological foundations of the implementation of the project of strategic innovative changes for construction stakeholder enterprises are justified: these foundations are formed through the integration of methodical platforms of enterprise economy, strategic management and construction development, which is considered as a target project and a regulated environment for achieving the planned improvements of the enterprise by stakeholders and changing the company's position on the market of construction works and services through the implementation of the intra-company strategic innovation project. The key to the success of the application of the created methodological basis for the needs of adaptation and development of the construction enterprise is the properly identified "state of adaptability of the enterprise and identified maturity to the implementation of changes." Within such identification, the limits of the situational-strategic maturity of the implementation of changes for the enterprise-stakeholder are stratified, and the economic features of the processes that take place in the enterprise at each level of maturity are summarized. It was determined that the provision of innovative processes for their development is provided by venture capital investment, each of which is characterized by the structuring of management technologies and the state of formation of the information and communication space.
