Shoring is the name of the game now as the process of shoring, forming and pouring the upper floor slab begins. Much the same process as the arena change rooms, shoring is placed and plywood laid on top to form the concrete floor. Certain areas are made deeper around the columns—these are know as slab bands which help transmit loads from the upper floor back into the columns and footings.
Shoring is comprised of scaffold like braces and aluminum beams which have a wooden nailing strip to attach plywood and other embers. All the forms are sprayed with forming oil prior to pouring concrete which allows the easier removal of the wood from the finished concrete. An incredible amount of steel rebar is used in these slabs for strength.
Once all the forming is in place, and in prior to the upper layer of rebar, Mayday Electric lays all the conduit and boxes required for electrical, alarm, data and security cameras. The conduit will be covered with a second layer of rebar and then encased in concrete. Here, Tyler and Morgan are running pulling twine through the lower conduits which will be tied to the wire bundles and pulled back to the appropriate area. The curling rink is serving as storage and staging areas for certain portions of the project such as many of the large electrical panels that will go into the main electrical room in the new aquatic area.
The former outside wall of the curling area (behind the curling storage lockers) is being insulated and sheeted for weather. This area is directly north of the elevator and stairs and will house 2 public washrooms just off the main lobby. This is left of where the main doors into the curling rink used to be. The photo below shows the block work by Casemore Masonry where the new refrigeration lines to the curling rink had to be located through 2 walls back in the mechanical room.
The new deep end of the 5 lane lap pool takes shape as the interior formwork goes up. Incredible detail is required on swimming pools as you can see all the ground wires which are required to every metal part in the pool as well as much of the steel which will be buried by concrete. The walls will be approx 16 inches thick by the time the concrete cures. A couple of items apparent on the formwork are the wooden forms (whitish wood in behind rebar) where the ladder will be to climb out as well lower and to the right is the form for the swimmers ledge which is an indentation where swimmers can stand in the deep end of the pool for competitions or just to catch their breath.
Below is the loading dock with the completed surface. Stairs will extend down the side of the building to serve as a fire exit for the curling, mechanical room and upstairs fitness room. A large air handling unit will be located in the corner next to the dock.. Above is the pool form - at the very bottom, the black strip is the rubber water-stop which will join the wall to the floor with a watertight seal. The pink Styrofoam blockout will serve for waterslide piping back to the mechanical room. While this phase of the project will not include a waterslide, some future infrastructure provisions are being made at this stage for economic and accessibility reasons. At the bottom, Bruce Healey, the Site Superintendent, is in a familiar position in his office as he talks on the phone while consulting drawings and managing the many trades on site.
