Transport officials in Ontario, Canada, will not be using more than 500 concrete girders fabricated for the $1.4 billion Herb Gray Parkway project after concerns of bunched cables and other issues. Many of the girders had already been installed, but will now be taken out. "[W]e found in some locations [the concrete thickness] was only one or two centimetres where it should have been six," said engineer Michael Hatchell, the parkway contractor's technical director. Officials say it's likely the contractor was trying to stay on budget and did not have "malicious intent."
