This paper presents a summary of some of the collaborations that were undertaken to ensure the successful completion of the Klang Valley Mass Rapid Transit (KVMRT) – Kajang Line in Kuala Lumpur, Malaysia. As a developing nation with the will and desire to construct the first MRT Project, the local joint venture company of MMC and Gamuda was presented with many challenges. To start the ball rolling, the team would have to make do with predominantly local resources. To meet the stringent requirements of the tunnelling fraternity and the underwriters, collaboration with the client and upskilling of the local industry players were necessary. While many of the points mentioned herein may be a norm in countries where Metro projects are already mature, the local construction industry in Kuala Lumpur still had a lot of catching up to do. The collaboration with the client, the site investigation contractors, laboratory/ testing agencies and geophysics service providers was instrumental in making the project a success.
