CA Drillers were engaged to execute the builders’ work package in collaboration with Morris & Spottiswood as part of the major refurbishment and CAT A/B fit-out of 33 Old Broad Street. Their responsibilities encompassed a wide range of tasks essential for structural modifications, service integrations, and overall site efficiency.
A significant aspect of the project involved creating vertical and horizontal openings through brickwork, blockwork, and reinforced concrete to facilitate service installations and access routes. This was accomplished through precise saw cutting and stitch drilling techniques. To ensure the structural integrity of block and brickwork penetrations, CA Drillers also supplied and installed prestressed concrete lintels. Additionally, core drilling was carried out in both vertical and horizontal orientations to form penetrations for various building services.
Another crucial responsibility was the installation of a temporary propping system to support the loading bay, allowing it to accommodate bulk deliveries safely. Furthermore, CA Drillers played a key role in constructing reinforced concrete plinths, which included the supply and installation of shuttering, concrete pouring—either by hand or pump—power floating, and the final striking off of the surfaces.
The scope of work also extended to soft stripping, which involved the removal of redundant services, tiling, and steelwork. Where required, block and brickwork infills were installed to seal redundant openings. To seamlessly integrate the building’s utilities within its structure, vertical and horizontal chases were formed.
Beyond these specialized tasks, CA Drillers provided general labour across the site to maintain tidiness and assist with the relocation of equipment and materials as needed. Additionally, they managed the supply and organization of skips, ensuring that waste materials were efficiently removed and that the site remained clear of debris.
Through their expertise and meticulous approach, CA Drillers played a vital role in facilitating the successful completion of the refurbishment project at 33 Old Broad Street.
