It is advisable that the technician who will measure the template, also, is the person in charge to fit the copings, as well. The material used for templates should be hard enough so its shape remain intact. Large curves can be imprinted by numbered patterns, but the individual parts of the pattern should be shorted out only in a sole combination.
Recording important dimensions, i.e. geometric chord or radius, during measuring patterns, may prove particularly useful verification method for the implementation of the order. A draft sketch that imprints a free pool shape, and on which is recorded every template, is particularly necessary.
On each template should be clear which is the top and the bottom side, which side faces the pool water and how many centimetres of overhang must be calculated during implementation.
