Abstract (EN): The WSS is a subsystem being designed and manufactured by the CENTRA team ( Portugal) for the ESO ELT first light instrument METIS. The WSS consists of three substructures - the support system (ELP), the alignment system (CAS), and the access and maintenance system (RIG). In total, the WSS dimensions are approximately 6 x 6 x 6 meters. In order to fully assemble, integrate, and test such a large structure, an integration hall of at least 2.5 times the WSS volume would be required to accommodate the necessary lateral and vertical clearance around WSS. Such integration halls are not readily available or accessible. In order to overcome this challenge, we have devised a 3-step strategy to assemble, integrate, and test the WSS at three different locations in three different configurations.
