Structural Renovations were instructed during the COVID-19 Lockdown to commence on site as soon as it was deemed safe to do so.
Prior to mobilising it was essential for the Company to have procedures in place to mitigate the spread of the virus between site workers, residents of the building and the general public. All operations to be carried out were risk assessed and control measures developed, such as increased PPE, staggered break times and regular sanitising of plant.
All individuals involved with the project received a site-specific induction regarding the actual works and separate Tool-Box Talk regarding the ongoing COVID-19 pandemic.
The works at Sheldon House, a 1960s, 7 storey, purpose built block of flats involved the removal of brick slips at each floor level to expose the reinforced concrete slab edges. The condition of the slab edges could then be assessed and a greater understanding of the building’s construction could be established.
Structural repairs were completed, including the installation of new stainless steel reinforcement and a migrating corrosion inhibitor; applied to pacify any ongoing corrosion within the existing reinforcement.
The repaired slab edges were then ‘built-out’ to the face of the brickwork using a structural, polymer modified mortar and once sufficiently cured these were primed and received two coats of pigmented anti-carbonation coating.
In addition cracks within the brickwork were repaired using Helifix approved repair systems.
All works were completed from temporary electric cradles, which provided a safe, suitable and economical method of accessing this type of repair project.
