UK Public Sector Contracts & Tenders

Project Keystone comprises the design, supply, installation, testing, commissioning, and handover of a comprehensive upgrade to the existing Building Management System (BMS) at CH, covering both the TS and CS. The site consists of two interconnected buildings in central London. Primary plant, including chillers, cooling towers, fresh air ventilation, boilers, and pumps, is located across basement and roof levels. Local systems are supported by supplementary plant on the office floors, where comfort conditions are maintained via a 4-pipe fan coil unit (FCU) system. The existing Trend BMS infrastructure is a combination of legacy and partially upgraded components, including IQ3, IQL, IQ4, and IQEco controllers. A partial system upgrade was completed in 2018, which included: - Replacement of selected IQ3 main plant controllers with IQ4 equivalents - Upgrade from Trend 963 to Trend IQVision graphical user interface - Integration of two separate site BMS networks into a unified IP network - Replacement of some IQL terminal unit controllers with IQEco units However, the 2018 upgrade did not address all legacy hardware. A significant portion of IQ3 controllers and associated I/O modules remain in operation. This project seeks to complete the BMS modernisation by: - Replacing all remaining IQ3 and IQL controllers with IQ4 and IQEco units, respectively - Removing obsolete I/O modules and integrating new hardware with existing field wiring - Rationalising the network architecture to ensure optimal performance and future maintainability - Enhancing the operator interface, trend logging, and graphical capabilities via IQVision - Integrating additional monitoring elements, including return air sensors, sump status, and alarm functionality The building shall remain live and operational throughout the duration of the works. The Contractor shall ensure minimal disruption to occupants and business operations, with particular care taken in occupied and secure zones. The works must be carried out in phases, with any required isolation or shutdowns carefully coordinated with the CH Facilities Management team and subject to prior approval. Contractors shall allow for the complexity of interfacing with retained services and ensure a thorough validation of the existing BMS network infrastructure prior to implementation. Any discrepancies between existing records and site conditions shall be identified and resolved as part of the scope.

This project involves the refurbishment and upgrade of the existing firefighting lift installation at CH, London. The scope includes the full removal and replacement of the lift car, associated shaft equipment, and integration with the building's fire strategy and life safety systems. Works are to be undertaken in a live, high-security diplomatic building, requiring strict adherence to security protocols, with minimal disruption to operations. The contract requires the provision of a compliant firefighting lift installation in accordance with BS EN 81-72:2020, BS 9999, and relevant Building Regulations, including Approved Document B. All works must meet or exceed the performance, safety, and accessibility standards expected for firefighting lift installations in a commercial/public building setting. Contractors will be expected to coordinate closely with heritage, building services, and security stakeholders, ensuring integration with existing infrastructure and minimal aesthetic impact on listed features. Specific interface requirements include BMS integration, fire alarm interlocks, and mechanical ventilation enhancements within the shaft to meet smoke control provisions. The successful contractor will be required to deliver a complete design, supply, installation, testing, and commissioning package, inclusive of all enabling works, builders' work in connection, and certification.

The works comprise the refurbishment and waterproofing of the existing sub-basement areas, including associated builders' works, drainage, mechanical, and electrical installations. The purpose of the project is to provide a fully tanked, dry, and serviceable environment suitable for long-term operational use within a high-security, heritage-listed building. The scope includes (but is not limited to): Careful strip-out and preparation of existing finishes to expose the underlying structure. Installation of a proprietary cavity drain and damp proof membrane system to walls and floors, complete with fixings, plugs, drainage channels, and connection to existing sump pits. Cleaning and re-commissioning of sump pits, including the supply and installation of new submersible sump pumps, float sensors, discharge pipework, and a new control panel interfaced with the Building Management System (BMS). Application of cementitious or resin-based tanking to identified areas, in accordance with manufacturer's data sheets and relevant British Standards (e.g. BS 8102:2022 - Protection of Below Ground Structures Against Water Ingress). Formation of new internal partitions, raised access flooring, ceilings, joinery, and decorations as required to reinstate the area following waterproofing works. Adjustment, modification, or reinstatement of existing building services affected by the works, including power, lighting, fire detection, and PAVA systems. Coordination with the Landlord's Facilities Management team and other ongoing building operations to ensure secure access, minimal disruption, and full compliance with Canada House site protocols.
