// CLIPS FROM ALL-TECH Environmental Services Limited
“I won't mention the name of the building but you know I was involved in a project years ago”
“One of the other big ones around here I guess is silica”
“Maybe just for your listeners, the phase approaches — phase one, phase two, phase three”
“Terry always had this idea and I remember him talking to me about it”
“If it's a public tender and it's a big retrofit, are you guys looking at that building”
“If a hotel owner is listening right now and he's got a situation like that”
“When I first came out of university that's where I actually started my career”
“They raised the Irving whale here in Halifax, pulled it up to the harbor”
“Just because you have that hazardous material in your home doesn't mean you may be exposed”
// LESSONS FROM ALL-TECH Environmental Services Limited
Buildings constructed between 1930 and the mid-to-late 1980s are almost certain to contain asbestos — treat it as a baseline assumption, not a variable.
Hazardous materials (asbestos, mold, silica) become dangerous when disturbed, not merely when present — contractors who understand the disturbance threshold make better abatement decisions.
Skipping a proper pre-construction hazmat assessment on a retrofit converts a modest renovation scope into a change-order spiral that can multiply cost and schedule by 3-4x.
Front-loading environmental assessment with the architect — before design is locked — produces comparable bid documents and eliminates the wild spread in tender prices caused by unknown hazmat scope.
Radon, the second leading cause of lung cancer in Canada, is controlled by building envelope tightness and geology — Atlantic Canada contractors should treat radon-resistant construction as standard practice, not optional.
Environmental site assessments (Phase 1/2/3) are increasingly required by lenders before financing property acquisitions — GCs and developers who build these into due diligence budgets protect their financing.
