Our work for NHS Grampian is ongoing. Examples of recent projects include asbestos removal works within the Special Block, Lift Mortar Room and a complex, large-scale asbestos removal project in the Link Building. 

Working on ‘live’ hospital sites brings many challenges and involves pre-start stakeholder involvement and consultation, then detailed planning and policing of works.  

For example, the congested nature of the surroundings requires careful planning and design of enclosure sizes, footprints, and construction. Transiting of double-bagged waste through occupied areas means that careful consideration is given to the location of skips/decontamination units and the use of sealed wheeled containers to move waste.  

 Achieving negative pressure is difficult and requires planning, pre-start involvement, discussions and agreement with the client’s appointed analytical company, over and above additional negative pressure units (NPU) capacity calculated and added. 

 Designing out dead spots within enclosures requires planning and design of enclosure sizes, footprints, use of NPU roving heads, and pre-filtered air inlets incorporated into the enclosures at points where air movement is required. 

 Being unable to vent NPU to the external atmosphere is another challenge which requires venting NPU exhausts into unoccupied areas. Careful planning at the pre-construction phase involving the analytical provider enables a suitable and sufficient air monitoring strategy to be developed for each area and scenario.
