The National Astronomical Observatory of Japan (NAOJ) has been responsible for the telescope structure subsystem (STR) of the Thirty Meter Telescope since 2012 and has engaged Mitsubishi Electric Corporation (MELCO) for preliminary and final design and pre-production work. There are various subsystems on the telescope, such as instruments and moving optics. Power and fluids and other services are required to operate these subsystems and the telescope drives. TMT provides the following services: Electrical Power and Bonding/Grounding, Fire Alarm, Communication and Information System (CIS) Networks, Fixed Temperature Chilled Water (FTCW) and Variable Temperature Chilled Water (VTCW), Hydrostatic Bearing System (HBS) Oil, Facility Compressed Air (FCA), Cryogenic System (CRYO), Refrigerant System (REFR), and Lighting (Operational and Emergency). The TMT defines the Telescope Utility Services (TUS) as the infrastructure which includes the cables and pipes used to deliver these utilities, the structures that support and route them, and the other components (electrical or piping components such as electrical cabinets or manifolds, lighting fixtures, fire alarms, etc.) necessary to provide these services. The design work to attach the TUS components to the STR was complicated due to the wide variety of TUS components and the multitude of mounting configurations and locations throughout the telescope structure. In order to efficiently integrate the various types of TUS components onto the STR, several practices were established and refined in the development of the TUS and STR design: 1. Definition of SOW between TUS and STR to enable concurrent TUS and STR design development 2. Simultaneous development of TUS and STR using CAD model 3. Piping and Cabling allocation within the Azimuth/Elevation Wrap 4. Route planning for cabling and piping 5. Seismic evaluation of TUS components In this paper we present the approach and the design implementation of the TUS components onto the STR.
