Conservation of concrete structures in fib Model Code 2010

Chapter 9: Conservation of Concrete Structures forms part of the forthcoming fib new Model Code. As it is expected that the fib new Model Code will be largely completed in 2010, it is being referred to as fib Model Code 2010 (fib MC2010) and it will soon become available for wider review by the profession. This paper is part of this activity. Chapter 9 addresses issues concerning conservation strategies and tactics, conservation management, condition survey, condition assessment, condition evaluation and decision-making, making interventions and the recording of information for through-life management. Chapter 9 incorporates the overall philosophy adopted in the development of the fib MC2010, which introduces a new integrated life cycle perspective upon the design of concrete structures. Accordingly, Chapter 9 provides a response to concepts introduced earlier within the fib MC2010 document relating to the service life design process, which requires the structure and its component parts to be allocated to a condition control category at the time of design. Different condition control categories are defined depending on factors such as the importance of the structure, its function, design service life, impact on third parties, environmental conditions, ease of maintenance and cost. Linked to these requirements, the condition control levels and inspection regimes are defined. A through-life management process outlined in Chapter 9 provides feedback to the service life design and allows updating of the associated theoretical model employed, facilitating assessment of compliance with the original design.
