Analysing the impact of partial replacement of basic concrete elements through WGP

The study's purpose is to analyze the impact of productivity in Indian transportation infrastructure projects. The study's methodology is to identify and analyse productivity attributes based on a literature review and expert focus group interviews. The identified attributes were identified and examined based on the respondents' relative weight. The data was gathered using a structured questionnaire across India, using both online and offline methods. SPSS 21 software was used to analyse the collected data. To analyse the collected data, quantitative research methodology was used, and the following tools and techniques were applied to the data: Reliability analysis was used to ensure the consistency of the data collected for the study, and the Relative importance index (RII) was used to set priorities and rank the attributes based on the weighted average score provided by the respondents. The study's findings show that planning and scheduling have the greatest impact on productivity in Indian transportation infrastructure projects, followed by construction methodology, storage area, poor construction method, and direction and coordination, with relative importance indexes (RII) of 0.79, 0.78, 0.77, 0.76, and 0.74, respectively. This study contributes to the current knowledge bank by identifying and analysing the impact of productivity in Indian transportation infrastructure projects. The study provides a solution for construction managers and project managers to apply the study's findings to their projects in order to control the issues of low productivity and project delays
