Fast Tracking the Pulau Poh Cable-stayed Bridge

The construction of the Pulau Poh cable-stayed bridge has been challenging both technically and environmentally. The curved pylon shape in two planes, with changing cross section and heavily congested reinforcement pose constructability concerns. Accurate geometry control and positioning of stay cable anchorages within the pylon is crucial to ensure the bridge meets its intended design life. Located in an area with high rainfall intensity presents additional environmental challenges, where working areas are constantly submerged. To address the challenges and meet the project deadline, innovative construction methodologies are being adopted. The bridge design was also revisited, taking into consideration the construction approach. This paper aims to explain the challenges faced and methods used to fast track the construction of the Pulau Poh cable-stayed bridge.
