PUB Contract – Box Culvert Upgrade from Marymount Lane To Marymount Road
Client: Chye Joo Construction Pte Ltd and Public Utility Board (PUB)
Tasks: Develop Road diversion schemes and conduct TIA study to assess road diversions
An old major box culvert needed to be upgraded under a busy junction which had a MRT tunnel beneath it. Initial plans developed by the PUB consultant suggested 15 stages of road diversions. Ali and his team later managed to develop alternative schemes which needed only 6 stages of road diversions. For each stage traffic impact assessment study was carried out to ensure the authority (LTA) would be satisfied with the junction configuration. Improvement options were suggested to ensure the main junction level of service maintained at an acceptable level D.
