SIKA AT WORK BATTERSEA POWER STATION, LONDON, UNITED KINGDOM 2 PROJECT DESCRIPTION This project features restoration and adaptive reuse of Battersea Power Station – one of the world’s largest protect- ed brick buildings – into a mixed-use destination with retail, offices, leisure and residential components within a 42-acre estate on the River Thames. The historic power station build- ing itself has c. 27,200 m² of floor area. Project phase 1 was mainly the substructure excavation and waterproofing activities for the Power Station’s basement and service tunnels which began in 2016. Phase 2 (the Power Station building, led by Mace as Construction Manager from August 2017) delivered the refurbishment, new energy center and riverside park. The Power Station opened to the public on October 14, 2022. Subsequent estate phases continue toward a multi-phase masterplan. The project was very complexed. Deep basements and service tunnels lie adjacent to the Thames; legacy steel grillages and interfaces with the original structural frame required intricate below-ground detailing, staged sequencing, and integration with the new Northern Line Extension and public realm. At the end, the redevelopment returned a decommissioned power plant (closed 1983) to public use, with phased openings since 2017 and the main building reopening in 2022 – now a major visitor destination and business hub. PROJECT REQUIREMENTS Reviving a Grade II* listed structure of this scale required an intricate balance between heritage preservation and modern performance standards. Durability and watertightness below ground Reliable waterproofing for a multi-story basement and service tunnels in close proximity to the river, with full watertight- ness around complex penetrations, grillages and movement interfaces. Heritage-led refurbishment Preservation of the listed fabric (brick facdes, turbine halls, control rooms) while introducing new uses; detailing had to be non-intrusive and compatible with historic materials and the existing steel/concrete hybrid frame. Phased construction & interfaces. System compatibility (rapid strength gain, minimized over- dig, optimized detailing) and coordination across multiple systems (basement, tunnels, parking, energy center, public realm), managed under a complex multi-contractor setup.
