This past couple weeks have been some of the busiest as far as prepping and pouring concrete. The lap pool is becoming a reality as the steel reinforcing mat and piping is now well hidden within the concrete. The boys from Razor Concrete and Craig's Redimix have been busy with 3 major pours - the north floor slab, the pool deep end floor, the hot tub floor and the south floor slab for a total of over 200 cubic meters. As a reference, your 24 foot square garage pad has about 6 cubic meters in it.
The orange caps you see in the photos are protectors for the ends of the rebar which can be rather sharp. Prior to any rebar and slabs being laid, the engineered backfill is compacted to meet a specific specification. The testing company determines compactness with a portable unit that has a rod with a small radioactive source which is set below the surface a specific distance then a detector (the yellow box) takes a reading and determines the density of the material between.
The Consultant team which includes the engineers from the various disciplines makes frequent site visits to ensure a strict level of quality and adherence to the design drawings is maintained. On the left, Rob Walter from AME Engineering takes some notes on piping layout in the hot tub while at the pool tank, Wendell Marshall, Project Manager examines the pre-pour prep with Site Superintendent Bruce Healey and Structural Engineer Wade Griffin to ensure all rebar, piping and water stop is in the proper locations. Part of the spec includes making sure a certain amount of concrete covers all pipe and rebar.
Charlie from the forming crew builds a trench drain blockout as the concrete truck rolls in for the first slab pour in the changerooms. The entire slab from north to south through the mechanical and change rooms was poured 2 separate days because of the quantity and ability to finish as well as finalizing some of the mechanical details. The slabs are poured, floated with a bull float and finalized with a power trowel for the finish required by the tiling trades. Sometimes, with all the concrete flying around, it becomes necessary to duct tape your boots to your pants.
Meanwhile, back in the curling rink, Zap Welding from Nelson has just about finished installing the steel members (red coloured) that give the lounge wall some badly lacking structure as well as properly tying to the roof. The old paneling was stripped off , exposing the yellow insulation and allowing for the attachment of the steel. Drywall and paint will soon be applied to the surface to cover everything back up.
After the pads are poured, control joints are cut in the concrete with a diamond saw. This helps to prevent cracking in areas where it is not wanted. In the background, Colin from Hedlund Contracting removes the gravel ramp built up against the wall that provided access for machinery into the change room area.
Rust never sleeps nor does progress on the Facility Enhancement Project as Acapulco Pool workers begin setting up the formwork for the walls of the deep end of the lap pool shortly following the pouring of the basin floor. Waterstop is incorporated into each pour which is a flat rubber gasket which spans new and old pours and ensures a water tight seal between all walls and floors.
