Contract CR112 was one of the first station contracts awarded for the Cross Island Line (CRL)'s first phase back in 2020. Since then, the contract has come a long way along but, as of Q2, had yet to commence tunneling work. This is despite the fact that a gantry crane being installed near the contract's launch shaft since January this year. Nonetheless, Q2 marked a significant milestone for the contract with the completion of phase 1 diaphragm wall works. This milestone also saw the excavation of portions of the station box commence.
