IN Brief:
- Farrans has been appointed to construct passenger skylinks connecting Stansted’s terminal with its existing satellite buildings.
- Sections will be preassembled in a vacant airport hangar and moved across the airfield overnight using self-propelled modular transporters.
- Completion will allow the existing track transit system to be removed, releasing space required for later phases of the £1.1bn terminal programme.
Farrans has been appointed to construct new passenger skylinks at London Stansted Airport, using offsite preassembly and overnight airfield moves to reduce disruption during a wider £1.1bn terminal transformation.
The walkways will connect the terminal directly with existing satellite buildings used for departures and arrivals. Their completion will allow Stansted’s track transit people mover system to be decommissioned, releasing space for later terminal development towards the airfield and changing how passengers move between the main building and gate areas.
Construction methodology is central to the package. Sections of the skylinks are due to be assembled in a vacant hangar on the north side of the airfield, away from their final positions, before being transported across the airport overnight on self-propelled modular transporters.
Moving more work into the hangar reduces the amount of assembly required beside live passenger and aircraft operations. It also shifts structural, access, and installation activity into a more controlled environment, where labour, materials, lifting equipment, and quality inspections can be organised without the same operational restrictions.
The difficult part moves rather than disappears. Completed sections still have to travel across an active airport estate, with route clearance, security, ground conditions, transport windows, and final installation coordinated around aircraft movements and other airside activity. SPMTs allow large assembled sections to move as single loads, limiting the number of disruptive transfers and reducing repeated work at the installation point.
The skylinks will include passenger travelators and routes for assistance buggies, giving passengers with reduced mobility a direct route between the terminal and gate areas. Their role is both operational and enabling: the structures provide a new passenger connection while allowing the existing transit system to be removed.
London Stansted’s wider development programme is valued at £1.1bn. Its centrepiece is a three-bay extension to the existing terminal, adding 16,500 sq m of floor area alongside a new shoreline check-in hall, improvements to the security hall, and the skylink connections.
Rob Stewart, MAG capital delivery programme director, said the project was moving “to the construction phase of the work” after Farrans’ earlier involvement in design, planning, and enabling activity. Carrying the same contractor into construction gives the delivery team direct knowledge of the operational constraints that shaped the proposed methodology.
Airport work is governed by interfaces that can dominate the programme even when the structures themselves are relatively conventional. Contractor access, security controls, passenger segregation, emergency routes, aircraft operations, restricted working periods, and airside permits can all determine where work can happen and how quickly.
The hangar assembly strategy responds to those constraints by reducing exposure at the final workface. It does not turn the skylinks into a standard modular building project, but it applies an offsite principle to airport infrastructure whose installation environment is more restrictive than its fabrication environment.
Safety is another driver. Preassembling larger sections at ground level can reduce work at height and limit the number of operations undertaken beside live airfield activity. The trade-off is a heavier logistics exercise when the completed sections are moved, making temporary works, transport planning, lifting and jacking arrangements, and installation tolerances critical.
The package also sits on the critical path for later development. The new passenger routes need to become operational before the track transit system can be removed, and that removal helps release the footprint required for subsequent terminal expansion. A delay in the skylinks can therefore affect work that is not physically part of the same contract.
That dependency increases the importance of testing and commissioning. Travelators, lighting, fire systems, accessibility provisions, controls, and passenger interfaces all need to be completed before the airport can rely on the new routes sufficiently to retire the existing transit system.
The construction sequence also has to account for the difference between building a structure and introducing it into live passenger use. Finishes, wayfinding interfaces, security boundaries, maintenance access, and operational procedures must be coordinated with airport teams before each route can be treated as part of the terminal environment.
Farrans is moving into main construction with the enabling logic already established: assemble as much as practical away from the congested airfield, transport the largest sections during controlled overnight windows, and minimise repeated work at the final location.
The test will come when those large sections leave the hangar. Stansted’s £1.1bn programme depends on the skylinks doing more than carrying passengers; they must be installed and commissioned with enough control to unlock removal of the transit system and the next phase of terminal construction without disrupting the airport around them.
