Introduction. As the foreign experience of many countries of the world shows, a fairly common practice in determination of the road works cost is the use of works cost evaluation method with the help of designed and constructed objects on the roads. Actually, for the preliminary evaluation of the road works cost on the early stages of design in Ukraine the method of evaluation of objects-analogues by using a comparative approach becomes more common. The comparative approach is one of the main scientific methods, which by comparison determines common and different characteristics, parameters in the process of objects studying, etc.Problem Statement. The research of the construction industry problems, in particular the determination of construction and designing works cost became the main topic of works of many scientists, in particular Berkuta A. V., Khaikin G. M., Kolesnikov O. V. and others. In general, the scientists raised questions of the construction works cost at different stages of project development, because the obtaining of such information gives an opportunity to perform economic evaluation of new projects and determine the effectiveness of the design solutions. The need for rapid cost information obtaining at the initial stages of project development is also particularly important, as this information serves as a benchmark for cost projections for the implementation of new objects. These factors are a prerequisite for the need to create a database of objects-analogues.Scientific justification of any process has a great importance in selection of the most effective ways for its realization. Economic science is facing new targets and objectives, the solution of which contributes to its development. An important task in this case is to implement and maintain the achievements of scientific and technological progress of the investment process. When developing a new investment project of new construction or reconstruction of a motor road a significant load falls on the pre- Збірник наукових праць «ДОРОГИ І МОСТИ» www.dorogimosti.org.uaISSN 2524-0994.

The pre-investment stage includes the development and approval of project documentation, which contains a feasibility study (drawings, explanation reports) and other needed documents. This stage is extremely important, because the development of the project is an important component in the overall implementation of the object and connects science with the construction process. The efficiency of future investments, the estimated cost of construction of the investment object and the terms of its implementation depend on the quality of the technological justification and the level of design solutions.The information and analytical system on the designed and constructed objects-analogues allows the customer to perform a preliminary evaluation of the road works cost at the early stages of designing. It is the study of the basic parameters and conditions that are essential prior to the beginning of the construction and that precede the implementation of construction solutions and identify a system of key indicators (economical, structural, technical) to compare the built object with the object, which is under construction. Indicators and criteria defined for the comparison of road objects, which are designed with the completed objects, make it possible to receive extended information and analyze it in the environment of the information and analytical system, which is based on the method of analog determination of the cost of road objects.Purpose. The purpose of this study is to analyze the information and analytical system for constructed and designed objects - analogues on public roads for prompt obtaining the information on technical, structural, economic indicators for preliminary evaluation by the customer of works cost within the documentation at early stages of designing.Materials and methods. The necessity of considering this topic is based on the application of one of the priority approaches to the cost evaluation - comparative, which determines the cost of the evaluated object by taking into account availability or lack of certain characteristics by this object in comparison with similar objects. The implementation of such comparative approach is possible when the needed information is available on the indicators of objects-analogous that are compared with the designed object. The comparative approach of evaluation involves carrying out a wide range of procedures with the validation of features (elements) of the comparison of the evaluated object and the objects-analogues; determination of quantitative dependencies of the parameters used for evaluation, adjustment of values of the investigated indicators and determination of summary results. During comparative evaluation of the objects a very important aspect is the validation of values (parameters) by which the comparison of road works objects is carried out.Results. Determination and analysis of the main criteria that affect the cost of construction and data collection on designed and constructed facilities on public roads, design documentation of which is agreed and approved in the prescribed manner, became the basis for creating of information and analytical system. Information and analytical system use makes it possible to determine the preliminary road works cost at the pre-investment stage of the project. This information shows the investor an approximate amount of investment required for road works on public roads and transport facilities on them.Conclusions. The method of comparative approach is one of the possible in the process of formation of the road works market cost as by both the customer and the contractor. The basis of the information and analytical system is the method of analog comparison based on a comparative approach. The comparative approach is applied by the analysis and comparison of technical and economic indicators of objects-analogues (identical or similar objects of construction), and therefore its application allows to receive real road works market cost. The use of this method is effective for determination of value of the object at the early stages of development of investment projects (feasibility study developed on the basis of initial data for linear objects of engineering and transport infrastructure, which require detailed rationale of relevant decisions and determination of options and feasibility of the object construction).Keywords:information and analytical system, road works, object - analogue
