“…This implies a need for optimizing design and construction procedures, enabling use of fit‐for‐purpose solutions and improving environmental performance, energy efficiency and cost‐effectiveness of construction technologies appropriate to the whole life‐cycle of the structures. It has been recognized that with the current state of knowledge significant steps can be made to improve the in‐service performance of structures (see Sakai et al ) and to incorporate efficiently and effectively the through‐life management strategy by considering this at the design stage (see Matthews et al ). Obviously, sustainability, through‐life management and life cycle perspective are important considerations for existing structures; however some additional issues apply as well, as discussed further below.…”

Discussions have been underway in fib (Fédération Internationale du Béton) about advancing the fib Model Code for concrete structures. These include the fib international workshop in The Hague (June 2015), the fib MC2020 Core Group meeting in Madrid (December 2015), and a series of follow‐up worldwide consultations on the fib ambition regarding the new developments in structural codes, including the special session on Model Code in the fib Symposium in Maastricht (June 2017). This paper discusses the main aspects of the development of fib MC2020, which is envisaged as a single‐merged general code fully integrating the provisions for the design of new concrete structures with matters relating to existing concrete structure. It needs to deal effectively with both the design of structures and all the activities associated with the through‐life management of existing concrete structures, including matters such as their in‐service assessment and interventions upon them. To that end, MC2020 will take sustainability as a fundamental requirement, based upon a holistic treatment of societal needs and impacts, life‐cycle cost and environmental impacts. This paper discusses the main aspects of the development of fib MC2020. As part of this, the envisaged contribution of fib T10.1: Model Code 2020 is reviewed. However, recognizing the overall ambition of the fib MC2020 project, it is clear that all fib commissions, along with other bodies able to make contributions on relevant topics, will need to work together to assemble the breadth of knowledge and expertise which will be required for the fib MC2020 project.

“…There are many different views on what it is and how it can be achieved [1,2]. Definitions of sustainability in various documents are somewhat general [3,4], slightly dissimilar, and do not provide clear principles for operational rules to satisfy desired objectives [5][6][7]. According to some, the definition is still under development [8,9].…”

The most important reliability approaches affecting sustainability in construction consist of the target reliability levels, verification methods, and construction or intervention procedures. The optimum target reliability levels can be specified based on probabilistic optimisation considering sustainability aspects including building costs, expected economic, social, and environmental consequences of construction, and possible failures. It appears that the derived reliability levels are strongly dependent on sustainability aspects and may be lower for the assessment of existing structures than for the design of new structures. The most efficient verification methods are based on advanced probabilistic approaches, including risk assessment methods considering actual properties of the structure and related failure consequences. It has been shown that sustainability in construction may be significantly affected by the design and assessment methods. The case study demonstrates that advanced reliability approaches commonly save 10–20% of the consumption of structural materials and natural resources.

“…With this as a background, the authors investigated sustainability design and proposed a design system . This design method includes systems to clearly establish the performance requirements to be considered with respect to social, economic, and environmental aspects, which are the three elements of sustainability; to calculate the attained performance based on the assumed specifications of the structure; and to verify if the performance requirements are met.…”

The World Commission on Environment and Development of the United Nations defined “sustainable development” for the first time in 1987, indicating the necessity for considering development that fulfils the needs of both present and future generations. However, the current situation of the sharp growth in the population and resources/energy consumption that adversely affects the global climate has been adding significance to the concept of sustainable development. From this background, the authors proposed a sustainability design system. This design method includes systems to clearly set the performance requirements to be considered with respect to social, economic, and environmental aspects, calculate the attained performance, and verify if the performance requirements are met. This paper describes the application feasibility of the sustainability design through the above procedures using an existing prestressed concrete viaduct. Additionally, comprehensive evaluation is carried out regarding the relationship between the elements of sustainability in comparison with the general method to clarify the effectiveness of sustainability design. It is concluded that sustainability design system has great potential of its applicability to concrete structures and promoting technical innovation based on setting of high‐performance requirements.
