Description

The High Luminosity Large Hadron Collider (HL-LHC) project is a major upgrade of the LHC operating at CERN, designed to enhance its performance by another order of magnitude. It involves the entire replacement of the machine and services over more than 200 meters on each side of ATLAS and CMS experiments and modifications across the LHC complex. In this context, the Integration team is responsible for the optimization and validation of the new machine layout for efficient installation, ease of maintenance, and flawless system operation.
The paper focuses on the challenges of this integration task. This includes the coordination of several teams and related design offices, adapting to spatial constraints of the existing infrastructure, managing equipment at various stages of design and dealing with interfaces between existing and new infrastructure.
The team employs a combination of 3D design tools and management strategies, such as interactive progress-tracking tools (JIRA) and robust documentation approval and archiving systems (EDMS). The integration relies on a complete 3D model from which the new reference Layout drawings and database are derived when milestones are achieved.
