Operating plant to remove structures during the London Fire Brigade (LFB) operation to extinguish the flames and smouldering debris was challenging.

Power intakes had to be considered live throughout the operation. Heavy smoke and contaminated residues from tyres had to be managed with the correct selection of appropriate PPE and RPE. Close coordination with the LFB Controlling Officer to ensure safe coordination was communicated between both teams to accurately deliver this challenging project.

Linbrooks London Road, Croydon Deconstruct UK Ltd August 2011 Dangerous Structures

Deconstruct to make safe structures in Croydon following devastating riots.

About the project:

Our services:

The project involved eleven structures affected by fires following street riots in August 2011. Numerous structures were left un-safe as a result of the fires and un-controlled collapses. There was significant risk of contamination from asbestos debris and also live gas and electrical services located in the footpaths and alleys. Around 30 families were made homeless as a result of these fires and a number of others faced a wait to re-enter their adjoining premises. Deconstruct were required to retain as much of the adjoining structures as possible and avoid collateral damage following the making safe of buildings clearly in need of planned demolition. The clear objective was to retain and return safe access to adjoining structures while opening this key road into and out of Croydon.

Linbrooks Rye Lane, Deptford Deconstruct UK Ltd August 2011 Dangerous Structures

Riots leave structures dangerous in Rye Lane, Deptford.

About the project:

Our services:

These structures suffered extensive fire damage as a result of the street riots in London, August 2011.

Adjoining structures appeared to be un-effected and so the aim was to demolish effected buildings whilst retaining adjoining premises. Temporary works were designed and methods developed to ensure speedy access for adjoining neighbours to enjoy safe access back into their premises.

Project challenges: Carrying out demolition from top down from within man-riders suspended from mobile cranes, whilst installing scaffold, designed temporary works was challenging. Clearing materials while aware of potential presence of asbestos and other contaminants was key. Fast track mobilisation and delivery to re-open the roads to ensure safe access to adjoining buildings was successfully achieved.

Linbrooks Enfield Sony Centre Deconstruct UK Ltd August 2011 Emergency Dangerous Structure

Deconstruct called to support the London Fire Brigade to extinguish this substantial warehouse fire following disturbances in Enfield.

About the project:

Our services:

Following a massive fire this structure continued to smoulder for almost three weeks. Due to the nature of the content of the warehouse and the fact the structure collapsed into itself, it prevented access for London Fire Brigade (LFB) to extinguish the flame.

Deconstruct provided specialist equipment to move collapsed structures, enabling LFB to access and douse the remaining hotspots.

These works were carried out by 25 and 45 tonne excavators with specialist attachments. The works had to be coordinated with the LFB incident controller and involved accessing the heart of the site, removing structural elements and then retracting to permit safe LFB access. These works took two weeks to complete.
