After an impact at a loading bay, it is easy to order a panel of the same thickness and a similar colour. The harder part is finding one that joins the adjacent panels and can be installed beside a working bay. Start by establishing the extent of the damage and identifying the existing system. Collect photographs, cover width, joint details and information about access to the fixings. An inspection will help the contractor decide whether a skin repair is sufficient or a whole wall section needs replacing.

A sandwich panel layout connects the building's geometry with the schedule of pieces to be ordered. It should show more than a wall or roof area: panel divisions, their relationship to supports and openings, and references to construction details also matter. Multiplying length by height does not produce a manufacturing schedule. This guide organises the drawing workflow: establish reference points, identify pieces, distinguish building dimensions from order lengths and record changes. Its focus is information passed between designer, installer and supplier. It does not prescribe universal support spacing or installation clearances. Those values must come from the solution developed for the particular building.
