BIM Driven Lean Construction: Leveraging Navisworks and Leica Geosystems for Enhanced Transparency and Efficiency on a Bridge Project

Abstract

This study investigated Building Information Modelling (BIM), specifically Navisworks and Leica Geosystems, in the design and construction of a bridge project in Lagos, Nigeria. To enhance transparency, reduce inefficiencies, and address corruption challenges within a lean construction framework. While the efficiency and effectiveness of BIM in achieving accurate designs through collaboration and coordination are established globally, its potential to mitigate corruption and inaccuracies in developing economies remains underexplored. This research bridges the critical gap by applying BIM and lean construction techniques to a real-world infrastructural project valued at over $ 50 million. The research design adopted incorporates semi-structured interviews with building professionals, including project managers, engineers, site supervisors, and surveyors, who are involved in the design and construction of the project. The data obtained from the in-depth interviews with key project stakeholders were transcribed and analysed through thematic analysis, highlighting key themes of transparency, anti-corruption, accuracy, and barriers to implementation. Findings show that Navisworks improved coordination through visualised clash detection, real-time tracking, and centralised data sharing, thereby reducing rework and corruption risks.

Additionally, Leica Geosystems enhanced surveying accuracy, thus eliminating setting-out errors that could incur rework costs. By demonstrating the advantages of lean construction driven by BIM as adopted on this project, this study offers an impactful perspective for improving outcomes and efficiency in similar infrastructure projects in emerging economies. Recommendations stress the importance of adopting BIM and addressing local barriers to its implementation. Through enhanced training, improving software interoperability, reducing costs, and fostering collaboration amongst stakeholders to build an enabling environment for BIM integration in emerging economies.
