Abstract: The subject of the study is the managerial relations arising in the process of shortening the duration of construction as a branch of material production engaged in the construction and reconstruction of buildings and structures for various purposes. The object of the study is: the construction complex as a whole; enterprises of various forms of ownership operating in the investment and construction sector; organizational and legal forms of interaction of participants in the investment and construction process; state regulation in the field of capital construction. The purpose of the work is to solve the key problems of construction time management: assessment of the duration of processes and allocation of resources. The author examines in detail such aspects of the topic as in-line organization of work; technological complexes of work; nomenclature of work; productivity of machines and mechanisms; daily number of shifts (shifts); intensity of work; planning of construction production; types of construction processes; construction crews; regulatory (directive) time of work. Special attention is paid to the specifics of calculating the composition of the team for roofing works.

The scientific novelty of the conducted research is determined by the insufficient study of the issues of improvement, theoretical, experimental and feasibility studies of technological processes, methods and forms of organization of construction and its production base, in terms of the problems of reducing the duration of construction. The significance of the work carried out for the national economy is to study the theory and practice of reducing the duration of construction and finding solutions to scientific and technical problems of construction by developing and creating competitive construction technologies and organizational and technological solutions that ensure the intensification of the processes of construction, reconstruction and modernization of buildings and structures while reducing labor, material, technical and fuel and energy resources.

Abstract: The subject of this research is the regulatory relations arising in the context of reduction of construction time as a branch of material production, which carries out the erection and reconstruction of buildings and structures of various designation. The object of this research is the construction sector overall; enterprises of different forms of property that functions in the investment and construction sector; organizational-legal forms of interaction between the actors of investment and construction process; state regulation in the sphere of capital construction. The goal of this work lies in solution of the key problems of regulating the construction terms: estimation of time and allocation of resources. The author examines the contractual models for the implementation of investment projects; factors that improve efficiency; technical and technological factors; organizational and economic factors; classification of construction works; role of general labor in modern industrial sectors; reduction of construction time; optimization of organizational issues; modern contact models; traditional model of organizing organization (M-1); EPC-contract model (M-2) ; construction based on EPC(M)- contract (M-3); factors that contribute to reduction of construction time due to the use of contractual models. Special attention is given to the causes and reserves for reduction of construction time in the instance of using various contractual models. The scientific novelty is determined by lack of knowledge on the questions of improvement, theoretical, experimental and technical-economic substantiation of technological processes, methods and forms of organizing construction and its production capacities with regards to reduction of construction time. The importance of this work for the national economy consists in studying the theory and practice of reducing construction time and finding solutions to scientific and technical problems of construction via development and creation of competitive construction technologies and organizational-technological solutions, which would intensity the processes of erection, reconstruction and modernization of buildings while reducing labor, material-technical, fuel and energy resources.

Abstract: The subject of this research is the regulatory relations arising in the process of reducing construction period as a branch of material production that carries out the erection and reconstruction of buildings and structures of different purposes. The object of this research is the construction sector as a whole; enterprises of various forms of ownership that operate within the investment and construction sector; organizational-legal relations between the parties to the investment and construction process; state regulation in the sphere of capital construction. The aim goal is to examine the key issues in regulating construction period; assess duration of the processes and allocation resources. The author focused on such aspects of the topic as the restricted (recommended) application of building regulations; actualization of the provisions of building regulations with regards to housing construction; development of the time or network schedules for building and construction works; enlarged construction costs standards; factors of variation of the construction period. Special attention is given to the rational variants of organizing the construction process for changing the normative duration based on the made decisions. The scientific novelty is defined by lack of knowledge on the questions of improvement, theoretical, experimental and technical-economic substantiation of technological processes, methods and forms of organizing construction and its production capacity with regards to the problems of reducing construction period. The importance of this work for the national economy lies in studying the theory and practice of reducing construction period, and seeking solutions for the scientific and technical problems of construction through development and creation of the competitive construction technologies and organizational-technological solutions that ensure intensification of the processes of erection, reconstruction, and modernization of buildings and structures while reducing labor, material-technical, fuel and energy resources.

Abstract: The subject of this research is the management relations that arise in the process of reducing construction time as a branch of material production that carries out erection and reconstruction of buildings and structures for various designation. The object of this research is the construction sector as a whole; enterprises of various forms of ownership that function in the investment and construction sphere; organizational-legal forms of relations between the parties to investment and construction process; state regulation in the area of capital construction. The purpose goal of this work consists in examination of national experience in solving the key issues of managing construction period: estimation of time and allocation of resources. Detailed analysis is conducted on such aspects of the topic as the economic component of management impact upon realization of a construction project; critical factors the internal and external environment of construction process and their causes; application of mathematical methods that calculate the likelihood of external influence based on evaluation of the impact of environmental factors; innovative component in project management.
