Bauer Technologies has been appointed to deliver specialist piling and geotechnical works for The Dovetail Building, a new 24-storey mixed-use development in the City of London.
The company was contracted by construction firm Deconstruct UK on behalf of client Brockton Everlast to provide foundation works for the high-rise project, which will transform a site in London’s financial district.
Phased Approach for Archaeological Work
The geotechnical works will be executed in two distinct phases to accommodate archaeological investigations by the Museum of London Archaeology.
This phased approach ensures that historically significant findings can be properly documented and preserved before construction advances.
Phase one is scheduled to run from November 2025 through February 2026. During this period, Bauer will remove existing piles from the site and install the majority of a new secant wall, which will provide structural support and water-tightness for the basement excavation.
The second phase is planned for June to September 2026. This stage will focus on installing a cased continuous flight auger (CFA) secant pile line along the party boundary with adjacent properties, as well as completing foundation and bearing piles that will support the tower’s structural loads.
Sustainability at the Forefront
Bauer Technologies has incorporated several environmental initiatives into the project delivery plan, reflecting the construction industry’s growing emphasis on reducing carbon emissions.
The company will use hydrotreated vegetable oil (HVO) fuel to power site equipment, significantly lowering the carbon footprint compared to traditional diesel.
Additionally, the project will utilize locally supplied blended cement, which reduces transportation emissions and incorporates lower-carbon cement alternatives.
Low-carbon reinforcement steel will also be specified for the piling works, further reducing the embodied carbon in the foundation system.
Major Development for the City
The Dovetail Building represents a significant addition to London’s skyline. The 24-storey tower will provide mixed-use space in one of the capital’s most prominent business districts, contributing to the ongoing evolution of the City of London.
Specialist piling and geotechnical works are critical to high-rise construction, particularly in urban environments where proximity to existing structures and complex ground conditions require expert engineering solutions.
Secant pile walls, such as those being installed by Bauer, create overlapping reinforced concrete elements that form a continuous barrier, essential for deep excavations in built-up areas.
The project continues Bauer Technologies’ track record of delivering complex foundation works across major UK developments, utilizing advanced piling techniques and equipment to meet the demanding requirements of modern construction.
Work is expected to commence this month, with the foundation package scheduled for completion by autumn 2026.
