Liverpool Street West Mall & Broadgate Link
Overview
The project was designed to dramatically enhance the retail presence of Liverpool Street Station. The two worksites were located within the West Mall and Broadgate Link.
The aim was to install blast resilient glazed curtain walling, carrying out an internal strip out and fit out to the retail units to provide the station with a vast increase in usable retail space and a harmonious retail presence.
Scope
The West Mall & Broadgate link project primarily consisted of creating enhance retail but first stripping out prior existing services and decoration to bring the units to a structurally sound blank canvas. The enabled Network Rail to commercialise the new units to prospective retailers. The units were formerly inefficiently laid out. Therefore, new ergonomic plans were agreed, and solid blockwork was installed to partition off the space into five separate units.
A full list of works is outlined as follows:
Design Development
- Intrusive package of surveys including a tag and trace of all building services
- Producing an accepted and approved GRIP 5 detailed design to NR standards
- Extensive Temporary works (FORM C)
Structural Improvements
- Structurally clear the units and strip back to shell and core
- Design and installation of specialist blast resistant Schüco glazed curtain walling
- Structural steelwork to restrain and include the glazed curtain walling system
- Replaced outdated tubular ceiling section in West Mall and Broadgate Link with a new
- Lowered ceiling height to create new CMS route (electrical, mechanical, fire, PAVA, CCTV)
Mechanical & Electrical Works
- Conducted extensive strip out of M&E redundancy
- Installation of new metered retail supplies; Power, Gas & Water
- Provided each unit with its own DB Board for individual retailer
- Upgrade the chilled water supplies to allow retailers uninterrupted usage
- Created a central utility area for Network Rail with a BMS panel for communication
Drainage Works
- Removed existing drainage and created new runs connecting to the existing system
- Broke through the existing slab for necessary depth and fall
- Produced a combined drainage system covering foul water, storm water, and grey water
Fire Safety & Service Corridor
- Upgraded fire cabling for retailer safety
- Installed a sniffer system in the service corridor to trigger sprinklers when detecting fumes
- Implemented fire compartmentation and fire stopping to prevent fire spread
- Created a corridor with CCTV coverage and VESDA fire systems
Challenges & Solutions
Logistics were challenging due to the site’s central, populous location. A traffic management plan designated Broadgate Link for smaller materials and Primrose Street for larger plant like glazing. Spence coordinated with the station to bring plant in during off-peak hours under banksmen’s guidance. The project also required coordination with the local council to comply with CO₂ regulations, traffic hours, and routes, and all suppliers needed FORS accreditations.
Spence also worked with the council to ensure noise restrictions were not breached by working off-peak, using acoustic barriers, and conducting noise monitoring and risk assessments.
A section of the works were located inThe clocktower which posed hazards due to its confined space and high fall risk. Confirmed space trained operatives and man safe systems were used through the element of works.
