Some products have qualities that might fade over time, or the sample has characteristics that don’t appear when installed on the building, or it looks different in the shade, in the morning, or at the sidewalk level. Managing expectations are paramount in the construction process.In order to manage Architect and Owner expectations, understanding the unique qualities of different products are important. If our project team has no experience with a product, we should be asking the Subcontractor and/or the Pepper Quality Department. (we are here to help!)One item that comes up frequently is oil canning in metal panels. This type of product will, to some degree, have oil canning that might not be expected or desired. Getting out in front of the potential issue is key to managing expectations and will avoid a conversation once the panels start going on the building. Also, understanding what could help the condition during specification or bidding will also minimize the condition and better manage expectations.

As we discussed before, not all fasteners that are zinc-coated are for exterior use…Whenever we are installing fasteners that will be exposed to the exterior, we should ask questions and verify the fasteners. This includes bolts, screws, expansion-type anchors, epoxy-type anchors, etc.
