Case Study: Lighthouse Cathedral Structural Stabilization & Remedial Works

Project Overview

  • Project Name: Lighthouse Cathedral Structural Assessment & Remedial Scheme
  • Location: 2A Carden Road, London, SE15 3UD
  • Client / Designation: Pentecostal Church Grade II Listed Building

Background & Historical Context

The site original contained a historic church building that was destroyed during WWII wartime bombing in 1940. The present building was subsequently constructed on the site and achieved Grade II listed status in 1972. Present day operations of the site are held by the Pentecostal Church.

Challenge & Problem Statement

The Grade II listed structure suffered extensive structural damage due to soil movement and root activity caused by an adjacent row of mature Lime trees. The damage was predominantly concentrated along the Northern aisle of the church, threatening the structural integrity of the heritage asset and requiring specialist engineering intervention.

Scope of Work & Engineering Solutions

PSL Engineers were commissioned to design and execute a comprehensive engineering solution to stabilize the building and safeguard it against future movement.

  • Full Survey Assessment: A structural survey and investigation to determine the exact extent, cause, and severity of the structural damage.
  • Options Study: An evaluation of viable structural remediation techniques balancing structural requirements against the heritage constraints of a Grade II listed asset.
  • Underpinning Scheme: Design and implementation of a structural underpinning scheme to reinforce the existing foundations along the affected area.
  • Remedial Works: Remedial structural interventions specifically targeting the Northern aisle to mitigate future influence from the mature Lime trees.

Outcome

The completion of the underpinning scheme and remedial works stabilized the structural foundations of the Northern aisle, mitigating any ongoing or future environmental effects from the adjacent Lime trees while preserving the integrity of the Grade II listed structure.
