Asbestos Removal at Brighton Police Station

May 06, 2016 Asbestos Removal

As part of a wider schedule of refurbishment works, Merryhill won the successful bid to remove positively identified asbestos from the John Street Police Station in Brighton. Working for Morgan Sindall major works out of their Brighton office, Merryhill were successful due to technical competencies and the ability to accommodate a demanding schedule, including working at night.

Asbestos containing materials (ACMs) had been found in a riser, plant rooms, lift shafts, basement car park and various other locations throughout the building. With various types of ACMs identified, the challenge was not only the number of items requiring removal, but also the conditions for access.

The removal took place in the winter to ensure the timely refurbishment later in the year. This posed a challenge as part of the works involved the removal of asbestos in a riser containing hot water pipes being used for the existing heating system. As all of the services would need to be turned off in order to carry out the removal, all of the works were completed out of hours. Although this meant an increase in cost for the client, it was necessary in order for our operatives to work safely. Carrying out the works during the day was not possible as the building needed to be fully operational and heated. In the riser, asbestos containing Amosite fibres was identified in various locations and deemed to be in a poor condition. As part of the asbestos removal, Merryhill carried out a full environmental clean including removal of contaminated non-asbestos lagging and fully cleaned the walls, floor and pipes.

In addition to the riser, ACMs were also removed from the basement car park in the form of mastic joints. A second phase of works has also been planned to include, the south wing of the building where 80m2 of flooring requires encapsulation, plus a full environmental clean of a boiler room.

The basement car park had a series of ductwork running across the ceiling and following a management survey, mastic containing Chrysotile fibres was positively identified. As the 40 linear metres of ducting required removal as part of the refurbishment works, Merryhill carried this out due to the presence of asbestos.

In a separate area of the building in the south wing, a section of the ground and first floors, including a stairwell had tested positive for a bitumen adhesive containing Chrysotile. As a new floor was going to be placed over the top of the existing, the client opted for the affected areas to be encapsulated, rather than a full scale removal. Merryhill is due to carry out the works soon, encapsulating using PVA to seal the floor where the bitumen was in a good condition. Any loose debris found will be removed as part of the works under controlled conditions.

Overall, the project to date has been a success and the client very happy with the end result. Speaking on behalf of Morgan Sindall, Andrew Burchell, Senior Quantity Surveyor said:


“Merryhill were a pleasure to work with over the course of the project and carried out all of the asbestos removal to an excellent standard, passing all of the necessary compliance testing. The refurbishment of the contaminated areas can now be carried out in a safe and professional manner and I look forward to the next phase.”


Steve Teale, Contracts Manager at Morgan Sindall said:


“Merryhill have been extremely professional throughout the project and have responded proactively when sampling & testing has been required at short notice upon discovery of unexpected potential ACMs. The night team undertaking the riser works, managed by Andy Hornby and led on site by Merryhill’s team, were first class.”
