	The operation of the Large Hadron Collider (LHC) at CERN started in September 2008. Every 5 or 6 years, Long Shutdowns (LS) are programmed to execute time-intensive ordinary and extra-ordinary maintenance of the LHC and its injectors. The second LS (LS2) started in December 2018 and was completed end 2020 for the injectors and early 2022 for the LHC. A huge number of maintenance, consolidation and upgrade activities, especially the upgrade of the injectors complex, were performed with challenges at various levels, from technical, to organizational and managerial. This paper presents the applied methodology put in place by the Accelerator Coordination & Engineering (EN-ACE) Group, in charge of the technical coordination of the activities for the interventions and changes to the LHC and its injectors, to ensure that the installation activities are performed safely, meeting the required high level of quality, while optimizing the schedule. It highlights key points of success and lessons learnt in terms of general coordination, quality assurance, configuration and layout management, spatial integration, planning and scheduling, operational safety, logistics and worksite coordination

	The European Spallation Source - ESS, has achieved its major construction in Lund, Sweden and is currently continuing in parallel to commissioning its first systems. ESS is characterized by installing and commissioning the most powerful proton LINear ACcelerator (LINAC) designed for neutron production and a 5MW Target system for the production of pulsed neutrons from spallation. The highly challenging and complex design of the Target and Neutron Scattering System (NSS) requires an in-depth analysis of the impact of the stringent manufacturing requirements and tight design tolerances. A campaign of several MECAmaster simulations was performed by ESS Target Division (TD) and Engineering and Integration Support (EIS) Division, focusing on those components that successively come close to their installation and are known for their criticality in terms of achieving the final installation tolerances. The aim of this current study is to investigate and statistically list the possibilities of eventual criticality on the assembly and installation processes, allowing for potential design optimization, tooling implementation and adjustment of the installation procedures.
