24、):2013-09 CWA 16633:2013 (E) 4 Introduction Managing assets is about making decisions. From this it follows that lifecycle cost (LCC) and in some cases lifecycle benefit/cost analysis is a critical concept for making investment decisions, and therefore should be incorporated in the engineering and m
25、anagement routines of infrastructure systems. However, several important questions remain before one may conduct a meaningful LCC analysis. These relate to the determination of the lifecycle of a new, maintained, rehabilitated or retrofitted structure and its expected performance along the lifecycle
26、 regarding the limit states. The impacts of uncertainty in estimating the risk involved in establishing appropriate demand envelopes for various limit events are significant for LCC analysis in design and in maintenance management. The present CWA was prepared by CEN Workshop 63 “Condition Determina
27、tion for Integrated Lifetime Assessment of constructed facilities and Components” the secretariat of which is held by ASI. It was developed through close collaboration with experts from the IRIS project “Integrated European Industrial Risk Reduction System”, supported by the European Unions Seventh
28、Framework Programme. Work in this project was organized in eight work projects. In the course of the IRIS project methodologies for lifecycle management of constructed infrastructure were developed. In order to meet the infrastructure owners governing requirements regarding safety, operability and d
29、urability, the present CWA addresses the following major aspects: 1) The determination/estimation of the design life of new structures 2) The determination/estimation of the residual life of existing structures 3) Assessment criteria whether the real degradation process determined by proper technolo
30、gies - corresponds with the assumed and applied life cycle model, in order to take corrective measures in cases of accelerated ageing 4) Maintenance instructions to ensure the intended service life In IRIS Work Package 3 and WP 7 and CEN Workshop 63 experts from universities, consultancies, public a
31、uthorities and standardization bodies contributed to the work. The present CWA has received the support of representatives of these sectors. DIN CWA 16633 (DIN SPEC 91298):2013-09 CWA 16633:2013 (E) 5 1 Scope 1.1 Ageing model The objective of the CWA is to elaborate a standard framework for the resu
32、lts of the IRIS Project, while it is recognized that there cannot be one extensive methodology fit for all specific industries. There is a simple basic model with considerable uncertainties, which is improved step by step through introduction and evaluation of new knowledge gained about a structure.
33、 The ideal result is a precise assessment of the condition with reasonable margins of uncertainty. The model is able to show the successive impact during the long-term deterioration process as well as the effect of sudden changes in condition (retrofit actions of local failure). It is recognized tha
34、t the individual results from visual inspection and assessment will influence the quality of the prediction. Nevertheless after a number of assessments these uncertainties will be reduced to reasonable levels. It is acknowledged that the basic model shall be kept simple and transparent for the end-u
35、sers. In return the background computation is expected to become more and more complex with every new knowledge and methodology developed. Therefore the concept is to give a common understanding on structural ageing in general, which can be incorporated into different industrial applications and ada
36、pted regarding the industry-specific demands. Figure 1 General concept of structural ageing In further consequence the focus of the CWA is on the area of bridge infrastructure, as there the most mature status within the IRIS Project has been reached. The aspect of acceptance of structural failure an
37、d accidents is always depending on the involved individual society. The current document already reflects the current situation in Austria, Germany, the Netherlands and the USA. DIN CWA 16633 (DIN SPEC 91298):2013-09 CWA 16633:2013 (E) 6 1.2 Background Asset management In the following an overall as
38、sessment scheme for asset management on the network level is described very briefly. The scheme is divided in two main processes: Flowchart 1: Input data with regard to Life Cycle Analysis (LCA) and Life Cycle Cost Analysis (LCCA) (as shown in Figure 2) Flowchart 2: LCA and LCCA itself, addressing t
39、he determination of maintenance schedules (composed by individual treatments) and linked to budget category-related optimization (as shown in Figure 3). In both flowcharts those parts, being explicitly covered by the current CWA are highlighted (yellow marking) and are discussed in full detail in th
40、e following chapters. It is to be pointed out, that the shown assessment scheme utilises conventional ratings (from structural inspection), which are usually available for every structure or can easily be provided. Neither the assessment scheme itself or the underlying rating process are intended to
41、 be standardized but the curve describing structural ageing (Lifeline). Thus the intention of this CWA is to improve the current practice of maintenance budget planning based on ratings. The given ratings are transformed into health indices and incorporated into comprehensive life cycle calculations
42、. By this means the gap between rating and service life considerations is bridged.DIN CWA 16633 (DIN SPEC 91298):2013-09 CWA 16633:2013 (E) 7 Bridge Inspection Condition - Bill of Quantities for existing structural members -Specification on Materials and Products - Ratings from Visual Inspection/mem
