There are numerous research on the constructability concept since its introduction in late 1970. After years of development, the trend of constructability research had moved towards the development of quantitative assessment models. There are many assessment models being developed for building projects but the models for infrastructure projects are still limited. The aim of this study is to propose a conceptual quantitative model for the assessment of constructability of river-crossing girder bridge designs at the design stage in Sarawak, Malaysia. Two stages of questionnaire survey were conducted in order to achieve the aim. At the first stage of survey, 143 responses were collected from professional engineers and G6 & G7 contractors in Sarawak. The collected data was analyzed using factor analysis and descriptive statistics of IBM SPSS Statistics. Subsequently, 7 major criteria of constructability principles and the constructability weightings of different bridge components were determined. At the second stage of survey, another 136 responses were collected from professional engineers and G6 & G7 contractors in Sarawak. The collected data was analyzed using descriptive statistics of IBM SPSS Statistics and Relative Importance Index (RII) method. Subsequently, the weightings of the 7 criteria of constructability principles and the Constructability Indexes (CI) of 119 girder bridge design alternatives were determined. The results of the two stages of survey were then integrated to form a quantitative constructability assessment model. This model is the first in Sarawak that can be used by professional engineers at the design stage to quantify the constructability of river-crossing girder bridge designs. By using this model, the assessment of river-crossing girder bridge constructability can be carried out more efficiently and effectively. © 2022, Construction Research Institute of Malaysia.
