Improvement in Highway Project Performance using Lean Construction

Abstract

Highway project delivery of new and reconstructed facilities consumes too much time and total cost of the project. The purpose of this thesis is to gain a better understanding of highway project delivery and enhances the time performance, reduction in cost applying lean thinking. This work presents several advantages of lean implementation. Highway project can be improved using lean construction, as it focuses on higher project performance and reduction in delays which directly influence the total cost of the project. Highway project that are located in urban environment exhibit greater relative risk of duration escalation. The duration escalation increases exponentially with increase of project cost. Therefore, the objective of the thesis will be the reduction in duration escalation and the overall project cost. The questionnaire survey was done with total number of respondents as 25. Relative Importance Index (RII) is adopted for ranking the delay causes as per their significance as it is simple and most widely used for finding the significant factors and ranking of the same. Primavera software is used to minimise the duration escalation and optimise the cost of the highway project.
