MRT-S5 Stations: Construction Engineering and Temporary Prestress Design for Construction of Segmental Cantilever Crosshead

• Alternative design on the prestress tendons for the precast segmental crosshead to comply to the required stress during stressing and segment erection.
• Design the temporary prestress bar for the erection of precast segmental crosshead
• Design the steel blister and holding-down system to anchor temporary prestress bars onto the precast segments during segment erection
• Carried out stability analysis on station structures during construction and advised contractor on the construction sequence to ensure stability throughout the construction.
• Prepared shop drawings for the precast segmental crosshead casting at yard.
