  1. CONCRETE PLACEMENT AND FINISHINGAndREW MERRICK

  2. Purpose of Meeting • Describe measures that will be used to place and finish concrete within the requirements of By-Law Number N-200 – Respecting Noise and minimize effects on neighbours • Review schedule of concrete placements

  3. Early Morning Start • 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.

  4. Pour Sequence • Sequence slab placements in a south to north direction to provide a buffer between work and South Street after initial placement.

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

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

  7. Light Direction • Lights when required to be directed away from South and LeMarchant Streets.

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

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

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

  11. 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.

  12. Schedule • When concrete placements occur, Aecon site office will be open and personnel can be contacted at 407-7730. • Estimated 26 slab placements to occur • First placement scheduled is basement slab on grade in mid-May • 3 placements every 2 weeks once level 3 slab is completed and typical floors start • Completion of concrete work scheduled for early November
