Despite the seeming simplicity of the cluster concept, the identification and monitoring of clusters is no trivial task. Clusters are not monitored by statistical services or stakeholders of civil-law relations; the list of participants is extremely volatile in clusters as it keeps changing as time goes by. Two methodologies are widespread in the West: 1. Methods developed by the European Cluster Observatory in EU nations; 2. Cluster Mapping Methodology by Harvard University in the US. The methodology of the EU is easy to use, implying calculation based on the statistical information of three quantitative clustering criteria: cluster specialization, cluster size and cluster focus. The American methodology is more complex and sophisticated in calculations which are based on cluster methods of searching for structure in sectors of municipal economy. Both statistical data and professional networking data as well as “input-output” matrixes are used as source data for clustering. Russian researchers also tap into foreign experience, complementing it with their own developments. Most often they use the experience of the EU Cluster Observatory, given that statistical analysis methods are practically applicable and affordable. A number of scholars complement these calculations with the factor analysis of economic sectors. Quantitative methods of cluster identification can be used to identify and monitor clusters and their participants in the urban environment for deeper investigation of this form of industry organization.
Social tension in the sector of housing and utilities, expressed in a large number of applications from citizens to all public authorities on matters of housing and utilities, keeps rising. With two thirds of the Russian population affected, this is a very important issue. An unfavorable condition of the housing stock is aggravated by underperformance of the routine repair, which accelerates the formation of worse defects requiring expensive major repairs and sometimes even renovation, which pushes up the repair costs. The article highlights the main problems related to planning and execution of the major repair works in multi-family houses (MFH). An innovative toolkit in the form of an automated information system is proposed, as a way to address management, economic and engineering problems in the national housing and utilities industry. Thus, using the graphical evaluation and review technique, the gradation of defects is proposed on the following MFH elements: load-bearing structures, cellars, facades and balconies. Also needed is another innovative tool in the form of an automated information system which will not only address the problem of collecting all available data including updates for the GIS HUI site through integration with other software systems used in the housing and utilities industry, but would also make calculations using new methods.
The organizational-technological reliability in construction is the capability of preserving the operational parameters within the set limits and arriving at the planned result under preset production conditions. Repair and revamping are resource-intensive works, so it is necessary to raise their efficiency using new approaches. The effectiveness of managing a range of works for property preservation and reproduction must increase for this goal to be attained.  Enhancing the organizational-technological reliability can be made effective with the help of competent mathematical tools for justifying the strategy of repair works. For the construction strategy to function smoothly, reliability losses in property repair and revamping need to be taken into account. It is this issue that the given article puts limelight on.
The main purpose of daily management of construction is ensuring the timely execution of the works. Timeliness is one of the three factors determining the effectiveness of construction. Untimely execution of construction works, defined via entropy, indicates the need of involving such additional managerial energy for organizing the construction process, which would rule out the untimely execution of works that was the case in the past. The given factor provokes the growing consumer cost of end products and affects the quality. The daily expeditious management presupposes continual impact upon the timely execution of planned works, using such tools as keeping executive documentation reflecting the actual execution of the work schedule, which allows to identify any disagreement with the planned dates. To minimize this disagreement in the future, construction management subjects must accordingly influence the construction process. The multiple nature of numerous regulatory functions is represented by overhead items, with a timely course of construction depending on their intensification. The author identifies and justifies eight items of overhead costs which directly affect the quality management of construction. In certain cases, the list presented can be modified by excluding some items and adding others which indirectly help addressing the issue of untimely execution of works. Proposed in the article is a model of optimal redistribution of the given expenditures indirectly related to the daily management of timely execution of construction works, which is accompanied by a block diagram showing conventionally the stepwise execution of construction works. Optimizing the cost distribution is complemented by respective expert evaluation methodology, since the task falls under the category of hardly formalized ones.
The major repair of multi-family houses (MFH) is based on the key principles of keeping the technological maintenance sequence: technical investigation (engineering survey), design, production of works, technical oversight, acceptance. They ensure the reaching of the set fireproof parameters for a building as a whole and its elements, the load bearing capacity of foundations at the stage of works' produc- tionand subsequent operation; using modern technological and environmentally friendly materials reducing the future maintenance and repair expenditures, and keeping the set quality standards at that; raising the responsibility of the customer (builder, investor) for keeping the respective requirements of regulatory documents at all stages of major repairs, keeping the environmental and technological safety standards, protecting the life and health of citizens, the assets of individuals or legal entities, state and municipal assets, precluding any activities leading the owners, users and consumers astray. Major repairs do not result in any change in the property maintenance service, but if major repairs are not timely done for some reasons, the residual operation resource of a building is depleted, which later increases the outlay on repair and maintenance operations. The departmental construction standards set the minimum duration of effective operation of buildings of various designations and structural specifics. The Russian regional authorities are empowered to make independent decision son the procedure of monitoring the technical condition of MFH, creating a regional operator, the terms of providing the government support for doing major repairs, the procedure of preparation and approval of regional major repair programmes as well as other matters, such minimum investments in major repairs, etc.
