Building Management System - North and South Portals at Old Oak Common (Tender Ref: COMM12)

Overview of the requirement: HS2 Old Oak Common (OOC) is a new high-speed rail station being built as part of the High Speed 2 (HS2) project - the UK's flagship rail infrastructure initiative. Once constructed Old Oak Common will be the largest newly built station in the UK. A key interchange between HS2, Elizabeth Line, Great Western Railway (GWR), and Heathrow Express services. Situated in West London, between North Acton and Willesden Junction and built on the site of the former Old Oak Common Railway depot. HS2 station will provide six high-speed Sub-surface platforms and eight conventional surface platforms for Great Western Main Line services (GWML) the combined station design will handle up to 250,000 passengers per day. The Euston Tunnel North Portal and OOC Tunnel South Portal buildings form part of the wider Old Oak Common Railway Station, providing the physical civil connection between tunnels and station constructed box, it also provides space for equipment. The design of the BMS for the portals is based on HS2 Technical Standard, Shaft and Portal Building Communications and Building Management Systems, this document will be provided with the ITT pack. The North and South Portal Buildings will operate a standalone Building Management System (BMS) dedicated to the Portal MEPH systems. The Portals BMS shall be designed to monitor and control only those assets designated as in-scope for the Portals in the applicable HS2 standards, the WSP RIBA 4(ii) design, and the Employer's Requirements, and shall not assume responsibility for any third-party systems outside this definition. The portals independent BMS shall be designed to monitor and manage the Portal building MEP systems. The East (North) and West (South) Portals BMS shall act as the central point for acquisition of asset performance data for analytical evaluation of equipment performance locally, asset maintenance and override for testing and maintenance purposes via access from NICC. The Portals BMS shall have a central PLC based system for control and monitoring of the designated Portal Equipment. All control logic shall be in the central PLC's, and all plant will use Remote Input/Output (RIO) units to interface with the field equipment. An exception to this will be life safety systems which will have their own redundant PLCs. All the field BMS outstations (RIO's) shall be connected in a fibre ring topology with the central PLC system. The BMS Subsubcontractor shall be suitable qualified with a proven record of accomplishment in delivering design, Installation and commissioning complex BMS systems in a railway environment, integrating a full suite of mechanical, electrical, HVAC, Drainage, Fire systems, and telecommunication systems.
