When determining the cost of capital construction objects, for purposes of pre-investment workings out and purposes of initial maximum initial price determination on tenders, construction price norms are used (CPNs). Modern CPNs are not designed to determine the value of high-rise buildings. It is necessary to adapt modern CPNs to get opportunity for the possibility to take into account special cost factors in determining the cost of high-rise buildings. The main ways can be: selection of new representative objects or application of additional correction factors.

Abstract Industrial and economic development is primarily applied to densely populated urban areas. If a sudden disaster occurs in such areas, the consequences can be severe. Shelter facility location affects the implementation of postdisaster relief work. This study explored residents’ perceived utility of evacuation time, their risk utility for road blocking, and the cost factors associated with constructing shelter facilities in the context of governance. A location model for emergency shelter facilities in cities was established on the basis of the aforementioned factors. Because the resolution of the random-weighted genetic algorithm (RWGA) is susceptible to influence from random weights, a robustness random-weighted method (RRWM) was developed. The validity and feasibility of the location model were examined through numerical analysis. Finally, the convergence of the RRWM was analyzed and compared with that of the RWGA and a single-objective genetic algorithm. The results revealed that the proposed algorithm exhibited satisfactory performance and can assist in evaluation and decision-making related to the selection of urban shelter facility locations.

The authors examine historical experience of application of standard designs in buildings. The relevance of the research topic is determined by the established and announced by the state goals of expansion of the use of model projects. These objectives are to accelerate the development and reduce the cost of the project documentation for the construction, improving its quality, the use of standardized technical and technological solutions and reducing the estimated cost of capital construction. The paper presents the current system of regulatory legal acts in the field of design in the construction of the model. The analysis of the main requirements to include information in the register of model project documentation, model project passport is presented. The authors view the prospects of development of model project system to meet the challenges associated with an acute social challenge - the resettlement of citizens from emergency and dilapidated housing.

The objective of this study was to determine the economic performance of alternative chipper choices for small-scale chipping based on unit cost (€ per chip-m3) and net present value (NPV) calculations. For the chipping cost and investment profitability analyses four tractor-powered professional or semi-professional disc chippers and two professional drum chippers mounted on a truck or powered by tractor were selected. Initial investment, operating costs, and the cost of outsourced chipping were the key elements for comparing the profitability of investment alternatives. The average purchase prices, cost factors, and technical details of the chipper units were acquired from machine dealers, specification sheets, a literature review, and interviews with chipping entrepreneurs. The results of the three tractor-powered professional chippers involved in the comparison were very close to each other. The profitable running of a truck-mounted drum chipper calls for high annual chipping volumes: the chipper type is therefore a feasible choice for an entrepreneur in large-scale chipping. Semi-professional disc chippers offer lower investment costs, but their economic feasibility is relatively poor.

Case Based

In this paper, we propose a hybrid case-based reasoning (CBR) system for predicting the construction cost of high-rise buildings at the preliminary design stage. First, the extracted cost factors (CFs) of a high-rise building were shown to significantly improve the cost estimation system’s performance. For developing a CBR system, a hybrid approach that combines CBR with genetic algorithms (GAs) for cost estimation was adopted. Genetic algorithms were used for optimized weight generation and applied to real project cases. Additionally, this paper proposes the identification of an alternative similarity score measurement formula. The proposed formula evaluates the contrast between the alternative case matching approach and the classical formula in a scenario involving the use of cost factors describing a case. The results indicate that the proposed GA-based CBR system can consistently reduce errors and potentially be useful to owners and contractors in the early financial planning stage. Accordingly, it is expected that the developed CBR system would provide decision-makers with accurate cost information to assess and compare multiple alternatives for obtaining the optimal solution and controlling the cost.

The Cost

Log and stumpage price formation in the United States and China appear mathematically identical, but are radically different. In the United States, prices are derived from the demand for final wood products in competitive markets. In China, prices are set centrally based on direct costs of production. The system is borrowed from Russia and is based on a theory of labor value that ignores time and interest rates. We explore the existing Chinese price determination model and Chinese proposals to change it, as prices have had little relation to the value of wood in use or the cost of wood from other sources. A cost-based model has few incentives to minimize costs of production, but ignoring the cost of capital has made stumpage prices abnormally low. Both systems are products of different philosophies of value and evolution in pricing technology must occur in the context of the parent economy.

Capital structure is described as a relation between equity and debts while the mutual consequences among items of company’s assets and resources employed as well as the cost of capital are also taken into account. Both, the theory and practice, at evaluation of approaches to capital structure are focu­sed on creation and optimization of capital structure. Relatively less frequent approach is the analy­sis of a state and of changes in capital structure on the level of whole business branch. But on this basis, it is possible to investigate some “average” approaches to selection of financial resources. At ca­pi­tal structure optimization (the proportion between equity and debts), a wide range of criteria plays a substantial role, e.g. cost of capital, risk, expected profitability, liquidity, dividend policy. These criteria have joint effect. This way, a logic question which criteria are preferred more and which criteria are preferred less appears. The article deals with the analysis of capital structure of three branches of manufacturing industry (the branch of production of plastics, the branch of production of electric equipments, the branch of production of textile) in the years 2007–2009 with the special focus on development of financial structure, capital structure and on cost of capital.

The issues of determining the estimated cost of capital construction projects with the involvement of Federal budget funds at the stage of development of project documentation, during verification of the accuracy of determining the estimated cost and the initial (maximum) contract price are considered. On the basis of the assessment of amendments to urban planning legislation for the purpose of implementing a state contract by the contractor ( based on the results of competitive procedures or without competitive procedures by decision of state authorities), the procedure for forming the estimate as part of a state (municipal) contract, the price of which is firm, is presented. For the purpose of mutual settlements between the customer and the contractor for the work performed, the formation of primary accounting documentation, as well as for checking the work performed by regulatory authorities, an example of drawing up an estimate of the state (municipal) contract on the basis of grouping costs according to structural elements and complexes of work is given. The result of the research conducted was the development of regulations and the formation of criteria for their practical application by state bodies, institutions, organizations and other participants in the investment-construction process, as well as recipients of budget funds, who perform the functions of the state (municipal) customer, developer and technical customer.
