Nowadays the leading trend in the construction industry is the creation of building information models of construction objects (BIM-models), which are able to accumulate information about all stages of design, construction of the object and its operation. Today the structure of BIM models includes several blocks that take into account architectural and planning decisions, the constructive part, the part of construction technology and organization, cost estimates and operation of objects. The article proposes to supplement the block “construction organization” with models for forecasting seasonality, since the organizational and technological parameters of the same type of processes can differ significantly when they are performed at different times of the year. The article suggests an algorithm for forecasting the effect of seasonality on construction processes, a database structure, which should accumulate data on deviations during construction, namely: deviations in cost, labor intensity and construction terms. The authors propose a methodical approach to identifying the effect of seasonal fluctuations on construction parameters and an approach to creating models that could be used for adjusting construction schedules, supplies of materials and technical resources, optimization of labor resources and planning of financial flows of construction projects. The proposed system will allow you to accumulate data on deviations of resources and financial flows of construction while constructing various objects and store them in the format of BIM models. The resulting database is the basis for creating dependencies that will allow taking into account the impact of seasonality on the construction parameters of similar objects or technologically similar works. Each season, the relevant database must be adjusted and supplemented. In addition, the digital model, if necessary, can provide information and practical experience on organizational, technological, financial, legal ways and methods of eliminating construction deviations and preventing risks

Introduction.Compliance of timing of construction works and supply of resources to the site with the works program is an urgent need, because any failure to supply or mismatch of schedules of works and the movement of materials and technical resources may have serious negative consequences for the construction process.Problem Statement. It is necessary to minimize deviations of actual construction terms from those specified in the design documents by creating tools for managing the organization of the construction process based on operational data, their mathematical processing, identification of trends and remedy of deviations based on current information on the course of construction.Purpose. To improve tools and means of the resource logistics and organizational and structural support of construction in order to minimize deviations of the actual terms of the supply of resources to the site from those specified in the design documents at the stage of design works and preparation of CSOS (construction site organization scheme) and SWEP (site work execution program) with seasonal factors taken into consideration. Materials and Methods. The research uses methods of expert estimations, seasonal decomposition of time series, and comparative analysis.Results. The analysis of modern software for the construction of construction, the scheme of organization of the construction project has been established, it is proved that seasonality is a factor that performs moderate influence on the terms of construction and supply of resources, created models of forecasting deviations of the course of the building process taking into account seasonality.Conclusions. The existing methods for forecasting deviations, which are used in the Microsoft Project, OpenPlan, Spider Project, SureTrek Project Manager, Primavera Project Planner, and other software should be added with models designed to predict realistic timelines with seasonal factors taken into consideration. K e y w o r d s : construction, seasonal fluctuations, construction organization, and term of works.

Вступ. Відповідність термінів виконання будівельних робіт і постачання ресурсів на об'єктах будівництва плановим показникам є нагальною потребою, адже порушення ритмічності надходження матеріалів, невідповідність графіків виконання робіт та руху матеріально-технічних ресурсів можуть спричинити серйозні негативні наслідки для всього процесу будівництва.Проблематика. Існує потреба в мінімізації відхилень реальних термінів будівництва від проектних шляхом створення інструментів управління процесами організації будівництва об'єкту на основі оперативних даних, їх математичної обробки, виявлення тенденцій та корегування відхилень на основі поточної інформації щодо ходу будівництва.Мета. Удосконалення інструментарію ресурсно-логістичного та організаційно-структурного забезпечення об'єктів будівництва, спрямованого на мінімізацію відхилень реальних термінів постачання ресурсів на об'єкт від проектованих, які визначено на етапі (стадії) розробки проектно-технологічної документації (проекту організації будівництва (ПОБ), проекту виконання робіт (ПВР)), з урахуванням сезонної складової.Матеріали й методи. Застосовано методи експертних оцінок, сезонної декомпозиції часових рядів, порівняльного аналізу.Результати.

Theoretical provisions on the formation of rational structural and technological solutions for the installation and dismantling of structural slabs with simultaneous assembly and disassembly of columns allow to improve the quality of the educational process by introducing it into the educational process. In accordance with the developed research methodology, the assumption that there should be structural and technological solutions for the installation of structural plates, which will meet the following criteria: accelerated speed of construction of single-story buildings, minimal labor intensity, increased reliability and accuracy, technical and technological possibility as an installation of structural plates, is accepted as a working hypothesis. slabs, as well as the dismantling of buildings without damaging the structures while preserving the possibility of their further use. The ranking of options for structural and technological solutions for the installation of structural plates was carried out according to efficiency criteria, taking into account the influence of factors according to the expert evaluation method according to the criteria of labor intensity, duration and cost of the process when assessing the reliability and quality of the processes. The technological process was considered in a full cycle, starting from factory production, transport operations, and ending with the erection of all structures in the volume determined by the task. The structure of the factors was considered in order to select them for further research. In accordance with the given methodology of numerical standardization of the labor intensity and duration of processes, the main factors were those that affect the number of actions, taking into account the movement of installers to certain distances, and those that affect the responsibility for the accuracy and reliability of the positioning of the mounted elements.

Gantt chart - considered an important part of project management, using the dates on the chart, you can accurately plan the delivery of materials, equipment, work of crews and subcontractors. The top level of the WBS is a project that represents the totality of the entire scope of work. The project consists of smaller works of different scope and importance, which are usually called work packages. The head of works often distributes work packages according to responsibility, assigning a responsible person to each package - an individual, a department, a subcontractor. In turn, each work package is subdivided into tasks or contains its own, smaller, internal work packages, the completion of which marks the end of work on the work package as a whole. Work on a work package is considered completed when the persons responsible for it (team) have completed all internal work packages and all tasks (events). A network diagram allows you to graphically establish the relationship between individual operations/work packages throughout the project area. The relationship and sequence between operations may vary from project to project, depending on the system you use in your work, the availability of funds, employees, etc. Actions are usually planned in a sequential order. Depending on the relationship between the beginning/end of previous and subsequent operations, four types of dependence are distinguished: finish-start – a new operation begins immediately after the end of the previous one; start-start – the start of the next operation is related to the start of the previous one, that is, in fact, two operations start at the same time; finish-finish - the finish of the next one depends on and is connected with the end of the next one, that is, two operations are completed simultaneously; start-finish – the beginning of the previous operation is connected with the end of the next one, that is, the finish of the next one is connected with the beginning of the previous one. When planning a relationship, you can enter lead time or delay time. The delay time creates a pause between the predecessor action and the successor action. The Gantt chart is the most important tool for designers. The schedule allows you to plan and coordinate the work of teams, agree on the delivery dates of equipment and materials, monitor the actual performance of work with the planned, make corrections to the planned work if the project starts to fall behind the schedule or costs exceed the budget, in order to focus available resources on the performance of tasks that will allow fix problems and eliminate delays.
