The train of allegations involving MTR construction projects linked to the Shatin to Central Link continued on Thursday.
This time, correction work carried out to fix an earlier flaw is said to have also gone wrong.
The Chinese-language newspaper Ming Pao reported that steel support beams that were put up at the future Exhibition Centre Station to correct an earlier flaw weren't installed properly.
The report said the beams the firm has put in are a metre away from where they should be according to the design plans. It also said the original subcontractor had refused to do the work, forcing contractor Leighton Asia to hire another firm to do the work.
The chairman of Legco's railway subcommittee, Michael Tien, said on Thursday that sources had also told him that the subcontractor had allegedly abandoned the Exhibition Centre Station project due to a money issue with Leighton.
Meanwhile, another bid by pro-democracy lawmakers to invoke Legco's special powers to investigate the Hung Hom Station scandal was voted down.
Democratic Party lawmaker Lam Cheuk-ting moved the bid, saying the MTR Corporation should be made to provide all the documents of its deals with contractors and subcontractors.
