IN Brief:
- Haringey has opened a restricted competition for £850,000 of work on Alexandra Palace’s Great Hall Bridge.
- The refurbishment is intended to improve waterproofing and building compliance while protecting a listed structure and emergency exit.
- Requests to participate close on 27 November; the provisional works period runs from January to April 2027.
The London Borough of Haringey is seeking a contractor for an £850,000 refurbishment of the Great Hall Bridge at Alexandra Palace in north London. Waterproofing and building compliance work must be integrated with the listed structure, while maintaining safe access to a venue that continues to host major events. The bridge also serves as an emergency escape route from the Great Hall, making its safety function central to the proposed intervention.
The restricted procurement procedure was published on 30 October, with requests to participate due by 27 November 2026. Shortlisted candidates would then proceed through the tender stage under the authority’s arrangements. The intended contract period is 22 January to 30 April 2027, giving the successful contractor a provisional window of just over three months for the works. Those dates depend on the competition and appointment being completed.
Great Hall Bridge provides access to one of Alexandra Palace’s major event spaces and forms part of the building’s means of escape. These two functions give the works a more specific purpose than the renewal of an isolated pedestrian structure. The refurbished route must support ordinary movement into and out of the venue and meet the applicable safety requirements for evacuation. Haringey is therefore seeking improvements that address both the physical condition of the bridge and its continued role within the building’s operating arrangements.
Waterproofing is a principal component of the intervention because water penetrating a bridge deck or its adjoining joints can reach the structural substrate and finishes. The repair design will need to establish the condition and continuity of existing protective layers and their connections to neighbouring building elements. Surface preparation, detailing at junctions and subsequent reinstatement are closely related tasks: defects in any one of them can compromise the finished waterproofing system. Haringey has not prescribed a membrane product in the published project description, leaving the final treatment to be specified through the works design.
The bridge forms part of Alexandra Palace’s listed fabric, so replacement or repair details must also protect the character and material of the historic structure. The contract covers the integration of new work with existing construction and building services, which may involve careful investigation before an intervention is designed. Areas affected by waterproofing or associated building work must be reinstated without compromising that fabric. Conservation requirements therefore sit alongside the practical need to provide a durable weather barrier and compliant public access.
Maintaining critical life-safety systems during the work is a stated requirement of the procurement. The construction plan must account for services that connect the bridge to the wider venue, together with any temporary arrangements required when access or systems are affected. Work on an escape route needs to be coordinated with the event venue’s operational procedures so the available evacuation arrangements remain suitable throughout. The published scope does not identify particular alarms, lighting circuits or other services for replacement.
The bridge’s dual use as a Great Hall entrance and emergency exit will constrain how contractors establish their working area. Public events continue at Alexandra Palace, and the authority specifies minimising disruption to the programme of activities. Before work begins, the contractor and venue operator will have to coordinate site access, segregation, the timing of disruptive tasks and any changes to movement routes. Refurbishing the structure while protecting public use and safe evacuation is an operational requirement of the job, rather than a separate phase left until handover.
The intended January-to-April programme brings the waterproofing and conservation work into the winter and early spring period. Exposure of existing surfaces, temporary protection, substrate condition and curing requirements can determine when a waterproofing detail is installed and closed up. Any interventions requiring access to the historic structure will also need suitable inspection and reinstatement arrangements. The timetable will depend on the selected contractor’s method and the venue’s permitted working periods, with the published date range remaining provisional.
The proposed £850,000 contract combines the building, waterproofing and operational interfaces within a single procurement package. Keeping the work under one appointment places responsibility for coordinating these trades and the site programme with the selected contractor. The scope addresses the bridge’s physical condition, public access, building compliance and conservation requirements together, reflecting its role within an occupied listed venue.
Requests to participate close on 27 November, after which Haringey can assess applicants and progress its restricted competition. A successful appointment would be followed by the detailed construction programme and site arrangements needed to preserve Great Hall access and emergency escape provisions. The provisional works period runs from late January through April 2027, with no contractor appointment or start on site confirmed at this stage.
