A Life Cycle Approach for Assessing Production Technologies In Heavy Oil Well Construction Projects

The objective of this experience report was to present the solutions used in the Management Process of the Construction and Assembly project of a Solar Photovoltaic Plant in utilitarian scale, in complex, uncertain and conflicting contexts. As a leading issue, it is intended to demonstrate that new approaches adopted in the project reported here – distinct from the traditional model and practices – allowed the mitigation of the main problems common to construction projects, including divergences between executive project and field activity, delays in delivery and deadlines initially contracted, and consequent additional expenses to the base budget. As a methodology, its theoretical foundation was based on bibliographic survey, addressing aspects such as: project management and life cycle ofthem,integration between the various processes and stakeholders, and Solar Energy on a utilitarian scale, in the scope of construction. This experience report aimed to discuss and demonstrate the approach used in the Guañizuil II A project, located in Argentina, in which agility, flexibility and innovation resulted in the mitigation of delays and additional costs, the achievement of notable records and the development of practical alternatives that can be applied to other construction projects. It is concluded that engineering projects, in their executive phase, need to be aligned with reality in the field, where an adaptive approach can bring positive gains and impacts throughout the life cycle.

Economic Well Being

The triple bottom line (TBL) principle encompasses the idea of continued economic and social well-being with minimal or reduced environmental pressure. However, in construction projects, the integration of social, economic, and environmental dimensions from the TBL perspective remains challenging. Green building rating tools/schemes, such as Green Rating for Integrated Habitat Assessment (GRIHA), Leadership in Energy and Environment Design (LEED), Building Research Establishment Environment Assessment (BREEAM), and their criteria, which serve as a yardstick in ensuring sustainability based practices and outcomes, are also left wanting. These green building rating tools/schemes not only fail to comprehensively evaluate the three dimensions (social, economic, and environment) and interaction therewith, but also lack in capturing a life cycle approach towards sustainability. Therefore, this study intends to address the aforementioned challenges. The first part of this study presents the concept of sustainable construction as a system of well-being decoupling and impact decoupling. Findings in the first part of this study provide a rationale for developing a methodological framework that not only encapsulates a TBL based life cycle approach to sustainability assessment in construction, but also evaluates interactions among social and economic well-being, and environmental pressure. In methodological framework development, two decoupling indices were developed, namely, the phase well-being decoupling index (PWBDIK) and phase impact decoupling index (PIDIK). PWBDIK and PIDIK support the evaluation of interdependence among social and economic well-being, and the environmental pressure associated with construction projects in different life cycle phases. The calculation underpinning the proposed framework was illustrated using three hypothetical cases by adopting criteria from GRIHA Precertification and GRIHA v.2019 schemes. The results of these cases depict how the interactions among different dimensions (social, economic, and environment) vary as they move from one phase to another phase in a life cycle. The methodological framework developed in this study can be tailored to suit the sustainability assessment requirements for different phases and typologies of construction in the future.

Complex Engineering Systems

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 Russian Federation

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.
