Attempt for an early morning start time within the by-law requirements
Goal is to get concrete in early so that it sets up early to allow finishing to start and be completed earlier.
If necessary, could be started later in the day to accommodate weather forecasts, inspections, etc.
Early Morning Start

Placement of Slabs
Place slab in thirds to cut down on the volume of concrete to be placed and finished

Erection of Wind/Sound Screens
Plywood barrier approximately 4 feet high erected to cut down on wind and sound transmission.

Faster Concrete Set Time
Money to be spent on admixture additives placed in the concrete to shorten set time

Concrete Placement Method
Traditional method with tower crane on site is to use concrete bucket for slab placements which is time consuming.

Concrete Placement Method
Slabs to be placed using a concrete pump which will increase the rate that the concrete is placed.

Concrete Placement Method
Supplement concrete pump with deck placer from level 3 to roof.
Articulating arm eliminates need to drag hoses over slab increasing placement rate.
