Case Study // Durham House – Interserve Facilities

Scope of Works

Erith were awarded the asbestos removal contract at Durham House in 2011 by Interserve Facilities Management. The contract incorporated removal and repair works to a former HM Revenue and Customs office block, which spanned 14 storeys in height.

The project involved the removal and repair works of asbestos throughout all floors of the tower block. During the entire project, the building remained occupied and fully operational. The works were programme driven due to the sensitive nature of working within an occupied premises and amongst highly sensitive IT equipment. The crucial constraint was due to the immovable start/finish dates, as a result of the logistics of reprogramming and relocating a great volume of sensitive IT equipment.

The specification itself included an extensive clean of all ceiling voids where AIB debris was present and encapsulating the fibre breaks to the central core. As the project was mainly repair works, we introduced a ‘go for green’ scheme to which AIB panels were removed and a non-asbestos green panel was inserted, accommodating tradesmen with a safe place to carry out operations within the void.


The staged programme was deadline driven and the dedicated site team managed transportation of plant/resources and the removal of all AIB and decontamination of all ceiling voids to create a safe working environment for follow on trades.

Erith worked hand in hand with the client to ensure the safest working environment was gained for all parties; with one of the building’s four lifts designated for all waste transportation. Waste was removed in bespoke containers specifically designed for this project – maximising the ergonomics of the scheme.

During the project constant air monitoring was undertaken, including background, leak and personal monitoring which was carried out by an Independent UKAS Accredited Laboratory of which Erith have formed a successful working relationship with over the past.
