INTRODUCTION Along with the development of the latest technologies in the construction of new structures, the reconstruction and major overhaul of existing buildings is also an important part of the construction complex, which needs improvement. One of the most common types of construction works performed during the renovation of buildings is the strengthening of reinforced concrete beam structures, namely: crossbars, floor slabs, coverings, beams, etc. Usually, in practice, to strengthen these structures, the following methods are used: increase in cross-section due to build-up; change of static scheme of work due to installation of tighteners, struts, racks, etc. 1 . However, sometimes the installation of additional, bulky, reinforcement designs is unacceptable because it causes changes in construction design and layout decisions of the interior space of the building at the same time significantly increasing the load on the bearings and the foundations. In this case, the method of reinforcing structures through external reinforcement is quite effective and advisable 2 . The principle of such

INTRODUCTION There is a large number of high-rise engineering structures in Ukraine and abroad. Most of them are operated by ten years or more. Many high-rise engineering facilities require repair work, and some – emergently. Such projects require a significant investment. As a rule, there are many options for the upgrade. They may have different costs, deadlines. The specificity of some objects requires a specific schedule (only on the night shift, the use of a limited number of people or calendar time). The regulations and information sources have no guidance on the selection of effective organizational and technological decisions at reconstruction of such buildings. The use of traditional building processes modeling methods makes it impossible to evaluate the effectiveness of variants of organizational and technological solutions. Modeling of these options and experimental analysis of statistical models will determine the best solution for the selected performance criteria.

INTRODUCTION The work is based on the research of leading scientists in the field of investment science and construction economics, presented in the monographs and articles by A. Gojko, L. Sorokina, V. Fedorenko, P. Kulikov, G. Rizhakova, I. Ivahnenko, O. Tugaj, T. Vlasenko, O. Bielienkova, K. Izmajlova та ін. The analysis of literature sources reveals that the individual means of project economic evaluation while building construction investment portfolio do not take into account complex investment risks, differentiated by their individual types, as well the liquidity of developer’s future assets, which significantly limits the ability to make informed decisions. It is revealed that the concept of «liquidity» in the investment process is synthetic and requires a double reflection on different objects: • in relation to investment objects, liquidity should be linked to the need to assess construction investment assets for their compliance with the planned values at all stages of the construction investment project implementation – from unfinished construction to finished construction products – and, further, to the object of profitable commercial use or social purpose 1 ; • the second important aspect of the concept of «liquidity» is related to the need to evaluate the reliability of the investor as a leading subject of the investment and construction process as for the ability to achieve real investment goals by providing the appropriate level of liquidity balance and solvency of the organization in terms of 4 group indicators 2 . This interpretation of the category of «liquidity» and the analysis of literature in several groups allowed us to formulate a scientific hypothesis of this work, which is as follows: “A leading requirement in providing a business process of real investment is a high level of liquidity of
这项工作是基于投资科学和建筑经济学领域的顶尖科学家的研究，这些研究在A. Gojko, L. Sorokina, V. Fedorenko, P. Kulikov, G. Rizhakova, I. Ivahnenko, O. Tugaj, T. Vlasenko, O. Bielienkova, K. Izmajlova та 的专著和文章中提出。文献资料分析表明，在构建建设投资组合时，项目经济评价的个体手段没有考虑到因个体类型不同而存在的复杂投资风险，也没有考虑到开发商未来资产的流动性，这极大地限制了做出明智决策的能力。结果表明，投资过程中的“流动性”概念是综合的，需要对不同对象进行双重反思:•就投资对象而言，流动性应与评估建筑投资资产在建筑投资项目实施的所有阶段(从未完工的建筑到完工的建筑产品)是否符合计划价值的需要联系起来，并进一步与盈利的商业用途或社会目的联系起来1;•“流动性”概念的第二个重要方面与需要评估投资者的可靠性有关，作为投资和建设过程的主要主体，通过在4组指标方面提供适当水平的流动性平衡和组织的偿付能力来实现真正的投资目标。对“流动性”范畴的解释和对几组文献的分析使我们能够为这项工作制定一个科学的假设，如下所示:“提供真实投资的业务流程的主要要求是高水平的流动性

INTRODUCTION Methods of engineering, process mechanization and automation, project organization and management are interrelated and geared at a common objective – to shorten periods and ensure quality of construction, to prolong life cycles of construction projects by applying engineering and technical solutions on automatic control of processes with the use of construction information models and technologies, data obtained by instrumental measurements at all life cycle stages. Designing of integrated models and methods of automated systems for diagnostics of building operating conditions is an initial stage of development of a complex automated system that ensures serviceability of buildings. Components for instrumental measurements and program processing of data are integral parts of the automated system. Therefore measurements and software are the basic elements for automation of engineering processes at all stages of life cycle of buildings.
