Temporary Shoring of Block Wall for Demolition Works

Project Overview

In Kincardine, Cico Scaffold was contracted by a large GC for a commercial client to provide a temporary shoring solution to support an existing block wall during demolition works below. The project formed part of a wider refurbishment and alteration programme within a live operational building, where safety, planning, and coordination were of critical importance.

The works involved the formation of a new opening in a load-bearing wall. This required the careful design, engineering and installation of temporary supports to allow demolition beneath without compromising the integrity of the retained structure above.

Key Challenges

The project presented several logistical and technical challenges:

Live environment: The works were undertaken in an occupied commercial building, requiring noise, dust, and vibration control measures, as well as clear segregation from the client’s ongoing operations.
Load-bearing conditions: The block wall supported structural elements above, demanding accurate placement of the needles and props to prevent cracking or movement.
Maintaining part of the wall: By installing the new load-bearing beam to the existing masonry and shoring to that saved time and money on the project without having to remove the entire wall and rebrick

Technical Approach

Following a site assessment and structural evaluation, the engineering team determined that a system of PERI steel props in combination with aluminum needle beams would provide the most effective temporary support arrangement.

The installation sequence included:

Marking to identify needle positions and load paths.
Carefully core-drilling openings for the insertion of needle beams at calculated intervals.
Installation of PERI props, needle beams, and spreader elements.
Ensuring secure head and base connections to prevent slip or displacement.
Monitoring during demolition activities.

Outcome

Despite challenges, the shoring installation and demolition works were executed safely and efficiently. The new opening was successfully formed, structural steel installed and the project finished on time, under budget, and with zero safety incidents.

The temporary shoring system performed exactly as designed, maintaining full structural stability and ensuring the retained masonry remained fully supported throughout the demolition phase.

Conclusion

This project in Kincardine highlighted Cico Scaffold’s expertise in temporary works design, shoring installation, and structural support during demolition. Through careful planning, precise engineering, and strict safety management, the team ensured that all works were completed efficiently and without disruption to the client’s operations.
