When choosing a construction company, it is important for the investor to assess its organizational and technological reliability, which affects the duration and cost of construction. It is proposed to use as a source of information about the reliability of the data on the development of capital investments by the construction organization for a fixed period of time. The purpose of the study – to offer a mechanism for assessing the organizational and technological reliability of the construction company in the construction of the Foundation. On the basis of the method of variant design all possible alternatives of simple technological processes in the construction of pile foundations were considered. Using the method of statistical testing of simulation models on each process flow, the most probable duration and cost of design work were determined. All the options for the development of capital investments were reduced to a statistical series, on the basis of which the curve of accumulated probabilities was constructed. On the curve of accumulated probabilities it is possible to determine the probability of building foundations at the right time with the required value of the index of development of capital investments. Variant design of the construction process allows to develop simulation models of construction of any foundations, on the basis of which the curves of the accumulated probabilities of the indices of development of capital investments for each type of foundations are formed. These curves serve as the basis for the investor in determining the organizational and technological reliability of construction organizations.

Состояние проблемы. В последнее время состояние удобства среды обитания современных городов становится более актуальной проблемой. Проделанный анализ поможет проектировщикам в решении задач улучшения архитектурного качества среды новых жилых районов г. Воронежа. Результаты. На примере деятельности ведущей строительной организации Воронежа анализируются недостатки реализации градостроительных объектов и рассматриваются пути их решения. В результате рассмотрения и анализа ряда реализованных объектов и объекта, намеченного к строительству, предлагаются пути улучшения архитектурно-художественного образа новых районов с учетом особенностей сложившейся городской среды Воронежа и современных тенденций передового градостроительства. Выводы. Поскольку любой застройщик заинтересован прежде всего в экономической выгоде строительства, он не может защищать интересы и потребности горожан, следовать историческим традициям города. Следовательно, на первых стадиях проектирования работы должны выполняться на конкурсной основе по заказу муниципальных властей, даже если застройщик является собственником участка, предназначенного под строительство. Лучший проект должен выставляться на торги среди застройщиков, обеспечивая победителю право строительства на данной территории. Statement of the problem.

In the current system of contract bidding, there are a number of problems, one of which is the imperfection of the evaluation criteria by which applicants are selected. The article presents a methodology for assessing the organizational and technological reliability of a construction organization and its competitive offers for tenders for construction and installation works. It is proposed to use the indicator of its organizational and technological reliability as a criterion for evaluating a construction organization that claims to fulfill a construction order. To determine the reliability of a construction company, information about the intensity of development of capital investments is used. This indicator allows you to assess how much the bidder can ensure the maximum return on the construction equipment and workers used, reduce the cost of construction using modern construction materials and resource-saving technologies. Each construction and installation organization will have its own intensity of development of capital investments. It depends on the qualification of employees, the availability and use of a fleet of construction machines and mechanisms, construction production technologies, construction organization methods, etc. As an indicator that characterizes the relative change in the actual development of capital investments from the standard or calculated value, the capital investment development index is used. Using retrospective data on the speed of capital investment development for similar objects or using variant design of the construction process, curves of accumulated probabilities of capital investment development indices are constructed, which are used to determine the organizational and technological reliability of the contract bidder. The proposed assessment of the reliability of a construction organization allows the customer (investor) to choose a reliable partner – contractor that best meets their requirements.

In the article, the author considers the problems of complex algorithmization and systematization of approaches to optimizing the work plans of construction organizations (calendar plans) using various modern tools, including, for example, evolutionary algorithms for "conscious" enumeration of options for solving a target function from an array of possible constraints for a given nomenclature. Various typical schemes for modeling the processes of distribution of labor resources between objects of the production program are given, taking into account the array of source data. This data includes the possibility of using the material and technical supply base (delivery, storage, packaging) as a temporary container for placing the labor resource in case of released capacity, quantitative and qualification composition of the initial labor resource, the properties of the construction organization as a counterparty in the contract system with the customer of construction and installation works etc. A conceptual algorithm is formed that is the basis of the software package for operational harmonization of the production program ( work plans) in accordance with the loading of production units, the released capacities of labor resources and other conditions stipulated by the model. The application of the proposed algorithm is most convenient for a set of objects, which determines the relevance of its implementation in optimization models when planning production programs of building organizations that contain several objects distributed over a time scale.

Freeways form an important part of the road network. Yet, driving behavior on freeways, in particular lane changes and the relation with the choice of speed, is not well understood. To overcome this, an online survey has been carried out. Drivers were shown video clips, and after each clip they had to indicate what they would do after the moment the video stopped. A total of 1258 Dutch respondents completed the survey. The results show that most people have a strategy to choose a speed first and stick to that, which is the first strategy. A second, less often chosen, strategy is to choose a desired lane and adapt the speed based on the chosen lane. A third strategy, slightly less frequently chosen, is that drivers have a desired speed, but contrary to the first strategy, they increase this speed when they are in a different lane overtaking another driver. A small fraction have neither a desired speed nor a desired lane. Of the respondents 80% use the right lane if possible, and 80% avoid overtaking at the right. Also 80% give way to merging traffic. The survey was validated by 25 survey respondents also driving an instrumented vehicle. The strategies in this drive were similar to those in the survey. The findings of this work can be implemented in traffic simulation models, e.g., to determine road capacity and constraints in geometric design.

The processes of environmental factors are milieu-focus, which  can influence the knowledge sharing in construction organization. This study examines the possible effect of environmental factors in respect to managerial leadership, strategy/planning and culture on the relationship to the knowledge sharing.  The study was carried out on project managers in construction organizations in Nigeria using a stratified random sample of 323 of  different designations. A hypothesized model of knowledge sharing, and environmental factors was tested using structural equation modeling approach, and a proposed model was therefore developed. All the factor loadings were significant, leading to a prudent model achievement. The study serves as a guide to the construction managers for sharing knowledge in the construction organization. The finding indicated that environmental factors demonstrated significant influence on knowledge sharing.

Acceptance Model

The Korean domestic market is focused on the introduction of BIM (Building Information Modeling) owing to an influx of investment due to increased interest and mandatory application of BIM. However, the rate of BIM introduction is high, while BIM user proficiency is low. Against these problems, the authors proposed an acceptance model for BIM in construction organizations in 2012. As the number of BIM application cases increases and the number of BIM-trained users increases as time goes on, BIM users’ positive perception of BIM values are expected to increase, which may change the BIM acceptance mechanism. Therefore, we conducted a longitudinal study of the 2012 BIM acceptance model against 2019 data to estimate changes in factors affecting BIM acceptance attitudes as well as the mechanism of the relationships between factors over time spent using the technology. To generalize the results, the respondents were spread across construction sites. The data obtained 119 samples from a sample of experienced users of BIM. We used AMOS 21.0 for hypothesis testing of structural equation modeling (SEM), and the 2019 BIM acceptance model was compared against the 2012 acceptance model using an independent sample t-test. As a result, it was confirmed that the 2012 BIM acceptance model is still suitable for describing the BIM acceptance mechanism of the construction organization, and there was a difference between the 2012 model and the 2019 model. This seems to have changed the mechanism of BIM acceptance by being change perception of BIM users as time goes on. The results of this study can be used to establish a BIM activation strategy for each BIM acceptance stage and are expected to be applicable to establishing a BIM activation strategy for construction organizations or countries with similar BIM acceptance stage.
