100 Liverpool Street

London, UK

This project involves the refurbishment, extension and enhancement of 65,032m2 (700,000 sq.ft) of existing office space that responds to modern occupier demands. Once complete, the refurbished building, located in the City of London, will be multi- tenanted with retail space located at ground and lower basement levels.

The scope for this project includes a new façade, additional floors, complete replacement of the lifts and building services, re-planning of the current cores and infill of atriums to create additional net area.

Appointed to provide MEP, Fire and Environmental consultancy, we carried out extensive site analysis which included daylight modelling and fire dynamic simulation. Our in-house Technical Advisory Group (TAG) were involved from an early stage, negotiating the upgrade of existing UKPN HV supply from 4MVA to 6.5MVA, which was crucial for the viability of the development. TAG also provided specialist knowledge in HV design by working closely with the project team to develop the HV strategy for the development.
