Superstructure Repair

Toppham Road, Sheffield

Project

A four storey block of maisonettes of cavity wall construction with concrete boot lintels, measuring almost 5 metres wide, providing support to both leaves of masonry.

The boot lintels at first and second floor level showed extensive signs of damage to the nibs and soffits. Chloride tests conducted by the Bersche-Rolt surveyor found a wide range of chloride levels, which were particularly high to one lintel.

Solution

In order to enable the replacement of the lintels, a load bearing design scaffolding was erected in conjunction with a temporary propping system, which was designed and installed in-house by Bersche-Rolt. 

As the tenants were to remain in residence throughout the works, extensive internal protection was erected between the working and living areas and to protect a conservatory at ground level.

Bersche-Rolt site personnel then carefully removed and replaced the damaged lintels before reinstating the surrounding masonry and render.
