The harsh environmental conditions inside wastewater treatment plants (WWTP) can cause significant deterioration and damage to the reinforced concrete structures that are necessary for the longterm operation of these facilities. In most municipalities and jurisdictions, the reality is that the existing sewer pipe network flows to only one location and there are no alternate sewage transport or treatment infrastructures available as a secondary backup in the event of the collapse or failure of a critical structural component.

Guidelines currently used by designers to estimate the unrestrained vertical deformations of masonry are based on laboratory observations of individual units (MSJC (2011), NRC (2010), ASTM (2010), BIA (2006), CEN (2005), NCMA (2005), CSA (2004)). However, research has shown that the effects of the mortar joints on the overall deformation of masonry walls are significant (Jessop (1980)). The presence of mortar joints should not be ignored when analyzing a masonry assemblage, particularly where the behavior of the units is dissimilar to the behavior of the mortar.

The First & Jasper office tower and underground parking structure was constructed in 1974 on a busy corner of Edmonton, AB, Canada. The project originally included a 20-story office tower; movie theater; concourse shopping level; and an underground, reinforced concrete parking deck. The underground parking structure consists of a slabon-ground and one uspended parking level, plus a suspended entrance/exit ramp structure providing access to the ground-floor level.

“Whether you’re conducting a BCA on a building you own or one you’re thinking of buying, you want to know its real condition. That means taking a very detailed look at everything from the building’s envelope to its mechanical systems and its structure,” says Bill Gladu, a Principal with RJC Engineers.

The short engineering answer is there’s too much snow when the design capacity of the roof has been exceeded. However, to the non-engineer who is tasked with maintaining the building, the answer depends on the geographic location of the building, its construction, exposure to its surroundings and whether the number of freeze-thaw cycles experienced during the season has caused ice to form on the building’s roof.

Data suggests that a condominium corporation should expect to spend between $100 and $500 per parking stall per year in order to keep its parking garage in good working order and build up savings for long-term renewal of the garage’s moisture protection systems. That’s the equivalent of $15,000 to $75,000 per year — or $8 to $42 per month per stall — for a building with 150 parking stalls.
