Work on site: May 2020

The first phase of works that were undertaken on site was to establish the areas within the three buildings that contained asbestos materials and to then identify what type of asbestos this was. This aspect of the works could only start once the buildings had been vacated and the site effectively became the possession of OSB.

The following report will detail each phase of works undertaken in a step-by-step process. The importance of following this strict procedure insures that the next phase of works can start safely and the various documents that are issued to the local authorities are approved before you can start the next task.
Phase 1 - Establish Site Exclusion Zones
Each individual property was fenced off to create a secure exclusion zone. This allows the team to establish safe working areas on site and to control the specialist tradespeople and their specific work locations on site. This also included erecting the fencing to the tree protection zones.
Phase 2 - Removal of Pews and Stained Glass
As part of the design brief our client requested that prior to any demolition works starting on site, a number of items within the Synagogue be carefully removed and placed in secure storage. Two of the main items where the stained glass windows and the pews.
Phase 3 - Identify Asbestos locations and Removal.
Within each building, every room is checked for evidence of asbestos. This will include the following areas, walls, ceilings, skirting boards, floor finishes, roof slates and surfaces that have been painted.

The specialist team then erected sealed air-tight rooms within the buildings to allow them to safely remove the asbestos materials. The operatives have to wear specific PPE equipment during this phase of the works and the air within these zones is controlled to stop any particular escaping to the outside atmosphere.
Phase 4 - External Demolition
Following the successful completion of the asbestos removal works, the demolition team began removing all non-load bearing elements from within the buildings. This included items such as doors, windows, stairs and bathrooms. These materials were removed from site in recycling skips. When this process was finished the large excavating machines started to demolish the buildings in a controlled manner.

When demolishing the external areas of buildings, the machines started on the roof structures and then carefully worked their way down to the foundations. During this operation they also used water-dust suppression machines to control any dust particles that escaped to the atmosphere. A dust monitoring station was also positioned within the site boundary and this allowed the team to remotely monitor the situation, from outside the demolition exclusion zones.
Phase 5 - Crushed Material from demolished structures
The final process upon completion of the demolition process is the crushing of the hard-core material. For this process the team introduced a crushing machine. This allows the solid hardcore material to be broken up into smaller pieces that can then be used on the piling matt.
