Having fun working on this mono stringer stair with open risers! Using tube steel for the stringer and uprights with solid 3" oak for the treads. Pan head screws will connect the steel plates to the treads for a clean look from below. The welded steel assembly will be painted black to contrast with the light oak.

Rebar inspection at EPCOR's Poundmaker substation. This is the base slab of an oil containment pit for a new 240 kV transformer. The slab is supported by 50 ft long (approx.) steel screw piles. Next up is the rebar, formwork, and concrete placement for the containment walls and transformer pad. Construction is on track for transformer placement at the end of the month.

This is a new reinforced concrete stair we are working on for Building Science Engineering (BSE). The stair, along with the new door opening through the existing grade beam, will provide exterior access for new mechanical equipment at Salvation Army Grace Manor.

We located the opening adjacent to existing piles to minimize the structural impact to the grade beams. We are going with steel screw piles given the challenges of installing concrete piles next to an open excavation. Voidform will be provided below the entire assembly to mitigate the effects of seasonal frost heave and the potential swell of high plastic clays.
