Procurement of a Contractor for the replacement of Diesel Rotary Uninterrupted Power Supply (DRUPS) at two FCDO UK locations

Resilience of power supply to King Charles Street (KCS). The operation of all the departments and services located at KCS requires electrical power for the most critical of systems to be provided without interruption. This project seeks to change the existing DRUPS critical electrical infrastructure to: • In the case of KCS a UPS that provides power via a battery system that provides power to the NO BREAK assets. • Diesel generators that provides power to SHORT BREAK & NO BREAK assets power demands. The works involves the removal of existing diesel rotary uninterruptible power supplies (DRUPS) and the replacement of them with traditional diesel generators and uninterruptible power supply (UPS) system’s along with the supporting cabled infrastructure, fire protection & detection, mechanical cooling services, control and monitoring system Activity to Date Based on the primary and critical recommendations of an initial condition assessment, a feasibility study was conducted in April 2021 as a follow-on activity from the initial electrical infrastructure assessment. Within this feasibility exercise was an intrusive load assessment of the key power nodes of the site to ascertain the sizing requirements of the additional generator and support systems. An initial stage 3 design was completed in June 2022 based on the recommendations of the preceding feasibility study. A peer review was then conducted by FCDO MEP leadership team, following this peer review the design was then updated to incorporate the comments made to enhance the central 11kV switchgear and central generator provision. Design to RIBA stage 3 on this revised scheme has now been completed. The procurement of the Contractor will be a Restricted above threshold tender procedure. We are exploring options to run the procurement as a ‘lotted’ structure and have the market bid for one or both projects. The recommended route to market is a 2 stage Design and Build from RIBA 4 onwards. These aspects of the project will be further explored in the market engagement exercise. The FCDO are looking for Contractors with experience in this specialist field and with a proven track record of projects dealing with key critical infrastructure of this nature and this scale. Case studies and in-house technical expertise will need to be demonstrated in terms of scale, technology and similar critical environments (e.g. financial, Government, or data centre)

Resilience of power supply to Hanslope Park (HSP). The operation of all the departments and services located at HSP requires electrical power for the most critical of systems to be provided without interruption. This project seeks to change the existing DRUPS critical electrical infrastructure to: • A BESS system that provides stored power to the NO BREAK assets via battery technology. • A diesel generator that provides power to SHORT BREAK & NO BREAK assets power demands • Install 2 new 11kV switchgear panels with modern intelligent controls. The existing main electrical building will be extended. • New mechanical cooling provided to the four main data rooms in building 38 with free cooling for energy savings. The works involve the removal of existing DRUPS and the replacement of them with traditional diesel generators and battery energy storage system’s (BESS) along with the supporting cabled infrastructure, fire protection & detection, mechanical cooling services, PLC control and monitoring system. Additionally, a new 11kV central facility will be constructed and installed as part of these works, and a new critical cooling system to one of the data centre buildings on campus Activity to Date Based on the primary and critical recommendations of an initial condition assessment, a feasibility study was conducted in April 2021 as a follow-on activity from the initial electrical infrastructure assessment.
