The article presents the results of a study of digital content reflecting conflicting urban communications related to road construction in Moscow. The empirical base of the study was data from social networks, microblogs, blogs, messengers, forums, reviews, and videos dedicated to the construction of transport interchange hubs (TPU). Date of material collection: 1.08.19 00:00 — 30.09.19 23:59. We used a multimodal approach to analyze the content of social media using neural network technologies, text analysis, content analysis, sentimental analysis, and psycholinguistic techniques. As a result of the research, the analysis of residents’ perception of the implementation of these construction projects was carried out, as well as social stress in the construction areas was identified, and the risks of conflicts with the population of Moscow were assessed when planning and conducting construction works. The analysis showed that five objects (TPU Varshavskaya, TPU Dmitrovskaya, TPU Nekrasovka, TPU Pyatnitskoe shosse, TPU Ryazan) do not have risks during implementation, the content differs in the absence of aggression and social tension. TPU Nagatinskaya is characterized by an average degree of social stress. A high degree of social tension is caused by the projects of TPU Michurinsky Prospekt and TPU Khovrino. Thus, the analysis allowed us to predict the absence of conflicts with the population in the implementation of the projects of TPU Varshavskaya, TPU Dmitrovskaya, TPU Nekrasovka, TPU Pyatnitskoe highway, TPU Ryazan. The construction of TPU Nagatinskaya and TPU Khovrino causes social tension, but conflict is expected only in the virtual environment. The content of the TPU Michurinsky Prospekt should be defined as a conflict-prone digital zone with a high degree of social stress, and the escalation of conflict between residents and city authorities, builders, both in the online and offline space should be predicted.

Currently, many road projects are performing poorly for timely completion, an analysis of time road project implementation needs to be done on the contractor company, so that it can be known that the shortcomings and weaknesses done so far, which later can be an input for contractor, to be even better in the implementation of time management of a road construction project. In 2017 many packages of road construction works in Sawahlunto City. The purpose of this study is to determine the factors that affect the implementation of time management of road construction projects in Sawahlunto. The research method used is quantitative research method by spreading questionnaires to the respondents involved in road construction project in Sawahlunto City. Kata Kunci : Time Management, road, late

The article is a continuation of the series of works on the method for risk analysis in surveying works in road construction projects. The paper presents the application of fuzzy logic to determine the nature and value of the risk of surveying works based on a database of rules and affiliation functions provided by experts. The fact that the issue of occurrence of risk factors in road construction works is not deterministic justifies the above. In such works, there are many uncertainties in establishing the value of their duration in the long term. The theoretical framework of the method is presented together with an example of its application. Moreover, research results are compared with previous publications using other research tools.

Secondary raw materials (SRMs) tend to be a valuable replacement for finite virgin materials especially since construction works (i.e., building and civil engineering work such as road construction) require vast quantities of raw materials. Using SRM originating from recycling a broad range of inorganic waste materials (e.g., mining waste, different industrial wastes, construction, and demolition waste) has been recognized as a promising, generally more cost-efficient, and environmentally friendly alternative to the exploitation of natural resources. Despite the benefits of using SRM, several challenges need to be addressed before using SRM even more. One of them is the long-term durability and little-known response of construction works built using such alternative materials. In this paper, we present the activities to establish a fully functioning digital twin (DT) of a road constructed using SRM. The first part of the paper is devoted to the theoretical justification of efforts and ways of establishing the monitoring systems, followed by a DT case study where an integrated data environment synthesizing a Building Information Model and monitored data is presented. Although the paper builds upon a small scale, the case study is methodologically designed to allow parallels to be drawn with much larger construction projects.

The most important measures stimulating the increase of efficiency and effectiveness of budget expenditures on road construction are the improvement of pricing mechanisms and increasing efficiency of the procedures of government purchases of goods, works and services. The paper includes the analysis of main problems that arise in the process of government purchases and construction pricing with the reference to budget expenditure on road construction. It includes the review and analysis of international experience and possible measures of increasing the efficiency and effectiveness of government purchases and (road) construction pricing in Russia.

Construction Works

Reducing the duration of construction works requires additional organizational measures, such as selecting construction methods that assure a shorter realization time, engaging additional resources, working overtime, or allowing construction works to be performed simultaneously in the same working units. The simultaneous work of crews may affect the quality of works and the efficiency of construction processes. This article presents a simulation model aimed at assessing the impact of the overlap period on the extension of the working time of the crews and the reduction of a repetitive project’s duration in random conditions. The purpose of simulation studies is to provide construction managers with guidelines when deciding on the dates of starting the sequential technological process lines realized by specialized working crews, for sustainable scheduling and organization of construction projects.
