Part of the botch on Waterloo St was allowing Grandlinq to put the TPSS there instead of across King as originally specified; the part that doesn't have the TPSS on it has electrical vaults under it. The other part — assuming no TPSS — was not putting in concrete box culverts before piliing the new tracks on top.
I would say the botch was the combination of (1) allowing Grandlinq to put the TPSS there with (2) not designing for a tunnel.
It is not believable that the TPSS and associated infrastructure couldn’t co-exist with a tunnel. But if the design of the TPSS doesn’t protect for the tunnel, it ends up putting cable vaults or whatever right where the tunnel needs to go.
Putting in the basic structure for the tunnel while doing all that other work would also have been a good idea.
