Currently, forensic methods and regulations in the field of construction do not explain how quality of work affects the procedure of forensic examinations and research related to determining the work scope. While carrying out building and renovation services, it is possible to control provided construction and renovation services,  establish their physical volume and quality. While research, forensic expert can identify violations of building codes, as well as determine the cost of refurbishment or elimination of defects made providing services. The scoop of performed works is determined by geometric parameters of construction elements, established during field surveys using design and as-built documentation. While carrying out field surveys, it is necessary (along with the determination of service scope) to pay attention to the compliance of the work performed with the requirements of building codes. The article outlines problematic issues and provides a list of basic indicators determining the scoop and quality of the construction works carried out, indicated in the reporting documentation drawn up by contractors based on results of activities in the field of construction. Actual issue arising in the establishment of the scoop and cost of construction work is considered  that quality does not meet the requirements of regulatory documents in the field of construction. It is explained how the quality of the work performed affects the results of research related to the determination of the actually completed volumes of repair, building and renovation and construction work.

In today’s scenario, construction equipment plants are essential for any construction projects and are also important for rapid progress and improvement in the quality of work. Breakdown and less productivity of equipment can increased the cost of construction project. Hence it is important that attempts to be made to increase the productivity of equipment. Earlier research has often addressed this fact, but it has rarely explained the causes and consequences of downtime. Thus this research paper highlights various causes of downtime of RMC plant and Transit Mixer. Also the downtime cost of RMC plant and Transit Mixer (TM) is determined by using mathematical model, COX Model and NUNALLY Model. These models are used to identify the downtime cost of equipment where COX Model gives the value by only taking into account of failure machine and not considering the impact, while the NUNALLY Model gives higher value due to considering the overall impact of failure machine on work.

In the presented article there will be discussed measures which allow to lower expenses for the maintenance of the machinery and which contribute to the increase of energy saving in general. To achieve these goals, it is proposed to apply modern methods of organizing and operation works, to use high-tech construction equipment, and also to form an optimal mechanization complex of building and construction works. The optimization criterion is the cost of work. When determining costs for the operation of construction machinery at the site, we take into account their energy efficiency, compare the options and manage the most efficient fleet of construction equipment. In the course of meeting the task, there were drawn conclusions which demonstrate that an integrated approach to the formation of machinery parks on the construction site allows to use the available resources more rationally, in order to improve the environmental component and improve the quality of construction work.

Strengthening the impact of the production and economic mechanism on increasing the economic efficiency of the production process and the quality of work is possible on the basis of choosing the most effective ways to achieve high end results of the national economic system of the country. One of these ways is the inclusion in the system of controlled parameters of the economic parameters of quality cost management, the use of which guarantees the quality coordination system to reach a given economically justified state. Adjustment of quality costs consists in maintaining the established proportions between the costs of quality assurance (quality) and the mismatch of work quality indicators, which is achieved by controlling the level of defects, maintaining certain conditions, rules and norms corresponding to the optimal mode of work on quality assurance and the optimal value costs. The quality assurance process is based on a classification represented by a range of activities aimed at ensuring the quality of tools, objects of labour, living labour and information data at all stages of the production process. The costing methodology is based on the selection of the costing object and costing units. Representation of work on quality assurance as an object of calculation, and hours of work or total amount of work as calculation units allows at the right time to present in value terms both the quality assurance process as a whole and the cost of quality for the product. The recommended mechanism of the cost management system in general is focused on a wide range of enterprises and associations, and its use allows to obtain the effect of minimizing the cost of quality, as well as improve the quality of work to ensure product quality, ice directly contribute to production efficiency and quality. Increase of economic benefit at the expense of cost control system solutions of the problem in the future is possible if its implementation on the basis of the theory of functional management development, conversion of static model into a dynamic coordination costs.

In this research the influence of natural and climatic conditions on the organization of construction production are examined. Our purpose was to identify the nature of the dependence of the duration of construction work on natural and climatic factors. The analysis of normative and technical documentation in terms of accounting for the influence of natural and climatic factors was made. The system of estimation of influence of natural conditions on preparatory, ground, facade, roofing works, and also the appliance of monolithic structures, installation of prefabricated ferroconcrete items, and on works – implementation of internal finishing is offered. It was estimated, that the norms of construction production take into account a certain number of natural and climatic factors affecting the performance of work, but most of these factors have not yet been given in the normative and technical documentation. It is necessary to study this issue more comprehensively and to establish exact dependences on natural and climatic conditions, which will allow to quantify these factors already while calculating. This is necessary to compile more accurate calendar plans and schedules of production of works, as close as possible to real conditions. The study of this issue is one of the most important issues in the design of construction production. With insufficient consideration of these factors, the final actual figures are very different from the projected ones, which also lead to an increase in the cost of construction and installation work and the duration of their implementation. Taking into consideration the influence of natural and climatic factors will allow planning construction production more accurate.

Abstract. The article considers the problem of evaluating, on a multicriteria basis, the quality of work of elements of the transport and technological system of the seaport.The method for evaluating the performance indicators of the transport and technological system of the seaport is based on the formation and comparison of a data array of conditional indicators of economic, environmental, social, functional and other types of effectiveness of this system.The management of the international transport system, which is the transport and technological system of the seaport, bears a rather complicated econometric character with the logistic principles of “compromise, non-interference, quality, risks” and others. A simpler is the assessment of quality on a multi-criteria basis using human-machine procedures, which is relevant for evaluating the operation of the transport and technological system of the seaport in modern conditions of deregulation. This is typical for seaports.The human-machine procedure involves the use of two possibilities: the first is reliably necessary and accurate data received from decision makers; the second is the development of an algorithm and program that allows you to speed up the calculations of the necessary estimates and establish estimates of the cost of the quality of work in the transport and technological system of the seaport.Particular attention when using the apparatus of human-machine procedures for calculating the quality assessment on a multi-criteria basis deserves the choice of weight criteria with an assessment of the “importance” of deviations of the cost of the work of a particular element from the indicators in the practice of individual elements of the transport and technological system of the seaport.The quality of work of the elements of the transport and technological system of the seaport should be assessed on a multi-criteria basis at the cost of achieving the value of the corresponding estimated efficiency indicator depending on the value of the cargo.A block diagram of the algorithm has been compiled to accelerate the calculation of the necessary estimated data for establishing an estimate of the cost of the quality of work in the transport and technological system of the seaport, which determines the coefficients of the weight of costs in evaluating the work of its individual elements.Thus, the developed method makes it possible to assess, on a multicriteria basis, the volume of costs, the efficiency and quality of work of any element of the transport and technological system of the seaport in uncertain conditions, especially when deregulating cargo transportation, as well as to outline and develop specific measures to improve the estimated performance of this system.
