This paper proposes a method for determining the bridge condition index (BCI) in concrete bridges, which is based on the views of bridge experts. First, eight indices were defined for a concrete bridge including structure, hydrology, safety, load impact, geotechnical and seismicity, strategic importance, facilities, and finally traffic and pavement. Each index consists of several sub-indices. Next, a series of questionnaires about the relative importance of indices and their sub-indices were prepared and distributed among bridge experts. Experts’ views were analyzed by Expert Choice software and the relative importance (weight) of each index and each sub-index was determined using the analytical hierarchy process (AHP). Then, based on experts’ views, an average score was assigned to each sub-index for any condition. Now the bridge inspectors can examine the bridge and determine the scores of sub-indices. Each index’s score is the sum of the weighted score assigned to its’ sub-indices and BCI is the sum of weighted scores assigned to indices. Higher values of BCI indicate a better condition. Therefore, bridges with lower BCI take priority in maintenance activities. To apply the proposed method, five bridges were selected in Semnan province, Iran, and BCI calculation of these bridges were conducted.

“…Though AHP offers a measure for checking the consistency of the overall survey result obtained using geometric mean still it does not prove the validity of responses even if the consistency ratio comes out to be lower than the threshold value of 0.1. Consistent responses do not mean that they are valid in practice, because a crazy person can be perfectly consistent about a non-existent reality [12].…”

“…The more appropriate way of calculating the relative weights of the factors is to use the priority weights to raise the judgments to that power and then multiplying them [12]. Priority weights for the judgments of an individual respondent may be assessed by calculating the respondent's consistency ratio and subtracting it from 1.…”

In Indian construction industry, decision regarding formwork selection is primarily based on the intuitive and subjective judgments of formwork experts. With an objective to rationalize the process of horizontal formwork selection, the research identifies from literature eighteen attributes affecting selection of horizontal formwork. These attributes were then statistically analyzed to yield six formwork selection factors, namely: building design and architectural features; job specifications and conditions; local conditions; quantity of formwork; available capital and site characteristics, and organizational support. Further, analysis of the extracted factors using Analytical Hierarchy Process (AHP) revealed that the most dominant factor that governs the choice of formwork system for any construction project is 'available capital and site characteristics'. However, to ensure an optimal selection, all the factors should be considered judicially. Furthermore, the research develops a quantitative Decision Support Model (DSM) for horizontal formwork systems. Performance analysis of the model through case studies revealed that the developed model offers more than 80% accuracy. Index Terms-horizontal formwork system, decision support model, analytical hierarchy process I. INTRODUCTION A. Role of Formwork Selection in Effective Construction Project Management According to Ministry of Housing and Urban Poverty Alleviation, in 2012, there was a shortage of 18.78 million housing units in urban India. Nearly 95% of this shortfall was in Economically Weaker Sections (EWS) and Low Income Group (LIG) housing etc. No wonder a large number of high-rise construction projects are being undertaken in residential sector in India. Selection of an appropriate formwork system is an extremely crucial factor for the successful completion of any residential construction project.
