The dirty work inside the building is almost complete. Rewiring a 200-year old heritage building with four-foot thick stone walls is a complex exercise. Grooves must be cut and plastered over when completed, which may cause structural problems if not done carefully. Some of the new sprinkler system pipes are nearly a foot in diameter. Figuring out where to put these new systems was a real puzzle. In some cases new wooden cabinets similar to existing college-era ones will be built to conceal this equipment. The puzzle continues when making connections outside, as archaeological vestiges must be taken into account. The Morrin Centre team is now hard at work choosing finishes for the surfaces, which will soon be plastered over.
