One thing I’ve noticed is that contractors almost always catch the “real life” issues that look invisible on drawings. Even small things like access for installation, material lead times, or how certain details will actually be built can save a project from expensive last minute redesigns.
In my experience, bringing them in early works best when it’s framed as collaboration, not correction. For example, even something as specific as choosing exterior components like
Canadian Choice windows can turn into a smoother process when contractor feedback is part of the discussion upfront, rather than after everything is finalized.
It’s really about avoiding that gap between what looks good in theory and what’s feasible on site.
