This opportunity, titled "Asset wide BMS Upgrade in Diplomatic Mission," falls under the "Mechanical signalling" industry category. The procurement is currently in the tender stage, with an open procedure method. The tender was published on 22 April 2025, and prospective contractors can submit their proposals until the deadline on 9 May 2025. The project is valued at £100,000 and is scheduled to commence on 2 June 2025, running through to 31 October 2025. The works must be executed in phases to minimise disruption, particularly in occupied and secure zones. This tender represents a significant opportunity for businesses, particularly SMEs, specialising in BMS installations and upgrades. Companies with expertise in interfacing new technologies with existing systems, and those familiar with the Trend BMS technology, will find this an advantageous project. The requirement to maintain building operations throughout the upgrade process calls for meticulous planning and execution, thereby favouring firms capable of handling complex installations with minimal interference. Engaging in this project could enhance a company's portfolio in high-security environments and strengthen their footprint in the UK’s engineering and facilities management sectors. ## Notice 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. ## Key Details | Field | Value | | --- | --- | | Publication source | Contracts Finder | | Latest notice | https://www.contractsfinder.service.gov.uk/Notice/1ed82c07-c877-48cf-855c-3fc263e309cb | | Notice type | Tender Notice | | Procurement type | Standard | | Procurement category | Works | | Procurement method | Open | | Procurement method details | Open procedure (below threshold) | | Tender suitability | SME | | Awardee scale | Not specified | | All stages | Tender | ## Dates | Field | Value | | --- | --- | | Publication date | 22 Apr 2025 | | Submission deadline | 9 May 2025 | | Future notice date | Not specified | | Award date | Not specified | | Contract period | 1 Jun 2025 - 31 Oct 2025 | | Recurrence | Not specified | ## Values | Field | Value | | --- | --- | | Tender value | £100,000 | | Lots value | Not specified | | Awards value | Not specified | | Contracts value | Not specified | ## Status | Field | Value | | --- | --- | | Tender status | Active | | Lots status | Not specified | | Awards status | Not specified | | Contracts status | Not specified | ## Buyer | Field | Value | | --- | --- | | Main buyer | BGIS GLOBAL INTEGRATED SOLUTIONS LTD | | Locality | LONDON | | Post town | South West London | | Postcode | SW1H 0BL | | Country | England | | ITL 1 | TLI London | | ITL 2 | TLI3 Inner London - West | | ITL 3 | TLI35 Westminster and City of London | | Local authority | Westminster | | Electoral ward | St James's | | Westminster constituency | Cities of London and Westminster | | Delivery location | TLI London | ## CPV Codes ### Divisions - 34 - Transport equipment and auxiliary products to transportation ### Codes - 34632100 - Mechanical signalling ## Release History - 22 Apr 2025 at 16:45 - Tender - Tender Notice - https://www.contractsfinder.service.gov.uk/Notice/1ed82c07-c877-48cf-855c-3fc263e309cb ## Documents - https://www.contractsfinder.service.gov.uk/Notice/1ed82c07-c877-48cf-855c-3fc263e309cb 22nd April 2025 - Opportunity notice on Contracts Finder - https://www.mytenders.co.uk/search/show/search_view.aspx?ID=APR169652 NOTE: To register your interest in this notice and obtain any additional information please visit the myTenders Web Site at the link provided. ## Provenance This Markdown file is an alternate public rendering of the D3 Tenders contract record.
