While the detector/ telescope design matured, the detailed mechanical design did not move forward with the same pace. This later led to a situation where the structural design needed to include a finalized detector arrangement. Since the simulation results were all based on the fixed telescope geometry, a late stage change in the cherenkov detector's mechanical support concept was very complex to include, mainly due to lack of available space between the detectors. So, in retrospective it would have been beneficial for some design aspects to detail the mechanical design parallel to the telescope design.
