Queens Quay, Glasgow

Contract Value - £31,578.00
Contract Type – SBCC Minor Works Contract for use in Scotland (2011 Edition).


The works at Queens Quay formed part of the ongoing £250m re-development of the former John Brown’s Shipyard site in Clydebank, Glasgow which aims to create a vibrant waterside community consisting of:

  • a diverse range of housing types,
  • health and leisure facilities,
  • office, bars and restaurants,
  • civic spaces including parklands, cycle paths and riverside walks.

The development is being led by the privately-owned civil engineering contractor, George Leslie Ltd, to whom Enviraz were subcontracted.

Enviraz works began in April 2018 and comprised in the removal and disposal of 110 linear metres of pipework complete with asbestos insulation from within the Bents (area under the quayside) using the wrap and cut technique. The pipework in question is a mixture of asbestos insulated pipework, pipework with asbestos residue, and pipework fully insulated with asbestos rope.


The works were undertaken within the bents area, located under the quayside, directly beside the River Clyde. Due to the proximity of open water, and risk of encroaching tidal water / depth variations, there was an inherent risk of contact with water bourn contaminants, leptospirosis and drowning. Operatives were issued with life vests by client during site induction which were worn throughout all works as a mandatory requirement, including asbestos works next to open water courses and for general transit on the dockside. In addition, the Client (George Leslie Ltd) erected a physical, timber, barrier around perimeter of bents, to prevent contact with watercourses.

The tidal waters also made the erection of an asbestos enclosure impossible, therefore additional control measures required to be implemented to reduce the spread of asbestos, as far as reasonably practicable. Enviraz utilised glove bags during the removal of small sections of asbestos materials, prior to the wrap and cut of pipe insulation.

Throughout all works, Enviraz implemented a programme of ongoing personal exposure monitoring and background reassurance testing by an independent, UKAS accredited, analytical company, to ensure that the safe working practices and procedures were effective.

Successful completion of these works, in an unfamiliar environment highlights Enviraz ability to work hand in hand with our client to develop and implement a solution to a unique problem. By utilising the appropriate resources and establishing positive working relationships with all stakeholders, Enviraz was able to complete the project on time, within budget and in line with the client’s programme.
