Abstract
The Search for Hidden Particles (SHiP) experiment is a new general-purpose fixed target facility proposed at the CERN Super Proton Synchrotron accelerator to search for long- lived exotic particles associated with Hidden Sectors and Dark Matter. This paper reports on the BIM integrated design of SHiP’s decay volume, a conical steel vessel under vacuum that should host several large particle physics detector systems. The use of BIM characterized the design of the decay volume, both in the modeling and structural design phase, and in the process definition phase for the realization and implementation in the facility of the device. This procedure helps to minimize the risks of incorrect design and construction of the device during the whole process. With the automation of the virtual model and the use of interoperable software, in addition to speeding up the exchange of information, it is possible also to export the detailed information of the structural design directly to the numerical control machines for the prefabrication of the various steel modules. Then, the BIM approach to support the integrated design of the SHiP project decay volume from the conceptual planning to the construction phase is shown in this work.

Summary
The Search for Hidden Particles (SHiP) experiment [1,2,3,4,5,6,7] is a new general-purpose fixed target facility proposed at the CERN Super Proton Synchrotron (SPS) accelerator to search for long-lived exotic particles associated with Hidden Sectors and Dark Matter. As part of the SHiP experiment, the use of BIM characterized the design of the decay volume, both in the modeling and structural design phase, and in the process definition phase for the realization and implementation in the facility of the device. The second detector system is dedicated to searching for decays of socalled Hidden Particles and allows probing a large variety of physics models with light long-lived exotic particles. To further ensure that signal candidates are not produced by neutrino or muon interactions in the upstream detector system or the decay volume walls, the decay volume is completely covered by a high-efficiency background tagger system, capable of detecting the charged particles produced in the interactions with the surrounding structure.
