Not really surprised by this timeline.
They delayed the full pit excavation while waiting on change application to demolish the old law office house which failed.
High water table changed engineering plans and resulted in only 3 underground levels.
CF their main contractor was stretched thin with tower 3 up in Hyde Park and finishing the Mosaik buildings on Sugarcreek.
Pandemic delays across all sub contractors.
Skilled worker shortage in region. Ie: Concrete formers, Steelworkers, General Laborers etc
And now they have CF starting another new building on Morgan Ave in south London. CF does not have a large work force. Drewlo is even smaller with their construction team.
