Endurance picks Multiplex for 99 City Road: design and services notes for engineers

30 Second Briefing
Endurance Land, part of Nan Fung Group, has appointed Multiplex as main contractor for the 36-storey 99 City Road office tower in London, designed by Kohn Pedersen Fox Associates. Structural engineer AKT II will lead the primary frame and foundations, while Arup is responsible for MEP systems and sustainability strategy. The appointment signals progression to detailed construction planning on a high-rise commercial scheme where integrated structural–services coordination and façade performance will be critical to meeting London office loading, comfort and energy targets.
Technical Brief
- High-rise construction in this dense urban plot will require just-in-time deliveries and tight craneage logistics.
- Temporary works design will be critical for stability of retained elements and neighbouring party walls.
- Coordination between AKT II and Arup will need early clash resolution for risers, cores and plant zones.
- Similar central London towers show programme risk dominated by utility diversions and third-party approvals rather than superstructure works.
Our Take
Within our UK Infrastructure coverage, London office towers above 30 storeys are increasingly being driven by overseas capital, and Nan Fung Group’s role here reinforces that international investors still see prime City fringe commercial schemes as bankable despite cyclical office-market concerns.
Multiplex’s selection for 99 City Road adds to a cluster of recent London high-rise contracts in our database where the contractor is tasked with complex urban logistics and constrained-site construction, signalling that its high-rise delivery record is becoming a key differentiator in central London tenders.
The involvement of Kohn Pedersen Fox Associates, AKT II and Arup on a 36-storey scheme aligns with a pattern in our Infrastructure stories where top-tier design and engineering teams are being assembled early on dense London sites, typically to de-risk planning around massing, wind, and transport interfaces rather than purely to optimise cost.
