Basement slab pour and truss preparation

With a favourable forecast we were able to schedule in the crew to pour both basement slabs and rear patios.  Without a shingled roof on the duplex, finishing flatwork concrete in the spring can be a risky situation.  Rain (or in our case more likely snow or frost) could cause serious damage to the curing concrete surface.  Fortunately the day was mild and the evening clear of storm clouds.  Use of a line pump and a series of concrete delivery trucks ready to go in the alley make the large area of pour proceed quickly.

Now that the slabs are poured and material ordered for basement framing, the framers can get started on the interior walls as soon as possible.  If bad weather is encountered, they may frame the basement walls before the roof is complete.  The crane also arrived to lift the trusses.  With the backyard clear of debris, access was good, with the exception of some low voltage lines that were quite close to top of the crane.  Fortunately the crane was able to safely back under the power lines and position itself far enough inside the property to access the roof.
