This paper investigates how the cost of structural health monitoring (SHM) technologies competitively fits into the life-cycle management of civil infrastructure. After a brief review of the aging infrastructure problem and a discussion of the technological, organizational, and societal complexities present, the need for synergistic adoptions-in-concert of common metrics, methods, and means of communication is addressed to develop a supporting platform upon which SHM systems can be developed and implemented. Using the costs associated with a recent bridge collapse, methods for the quantification of the utility of SHM are demonstrated. These methods include expanding upon existing and accepted practices, employing risk-based decision making, and calculating the benefit of monitoring in reliability-based life-cycle management models.


Improving the efficiency of life cycle management of capital construction projects using information modeling technologies is one of the important tasks of the construction industry. The paper presents an analysis of accumulated domestic practices, including the legal and regulatory framework, assessing the effectiveness of managing the implementation of investment construction projects and of complex and serial capital construction projects, as well as the life cycle management of especially dangerous technically complex and unique capital construction projects using information modeling technologies, especially capital construction projects, as well as their supporting and using systems, primarily in the nuclear and transport sectors. A review of modern approaches to assessing the effectiveness of life cycle management systems of complex engineering systems in relation to capital construction projects is carried out. The presented material will make it possible to formulate the basic principles and prospects of applying approaches to assessing the effectiveness of the life cycle management system of a capital construction project using information modeling technologies.


The variants of the division of the life cycle of a construction object at the stages adopted in the territory of the Russian Federation, as well as in other countries are considered. Particular attention is paid to the exemplary work plan – "RIBA plan of work", used in England. A feature of this document is its applicability in the information modeling of construction projects (Building information Modeling – BIM). The article presents a structural and logical scheme of the life cycle of a building object and a list of works that are performed using information modeling technology at various stages of the life cycle of the building. The place of information models in the process of determining the service life of the building is shown. On the basis of the considered sources of information, promising directions for the development of the life cycle management system of the construction object (Life Cycle Management) and the development of the regulatory framework in order to improve the use of information modeling in construction are given.
