A critical RAAC roof replacement project at the University of Edinburgh’s Appleton Tower has been successfully delivered using Procurement Hub’s Major Projects Framework 2 (MPF2) providing a compliant, efficient route to market for complex public sector construction works in Scotland.
The project demonstrates how early contractor engagement and framework procurement can support the safe remediation of reinforced autoclaved aerated concrete (RAAC) in live educational environments.
The University of Edinburgh identified reinforced autoclaved aerated concrete (RAAC) within the roof structure of two lecture theatres at Appleton Tower, requiring urgent structural intervention.
Procured through MPF2 under a design and build contract, the works delivered by Robertson Construction Central East included:
Full removal of existing RAAC roof planks
Removal of associated steelwork
Installation of new structural steel truss systems
New purlins and metal decking
High-performance Bauder bitumen roofing membrane
Roof design futureproofed for potential photovoltaic (PV) installation
The project required specialist structural expertise and careful planning to ensure safe delivery within an operational university campus.
RAAC Remediation in a live university environment
One of the key challenges was maintaining business continuity while undertaking complex structural replacement works. Robertson ensured that all M&E services in occupied adjacent areas remained fully operational throughout the project. Existing mechanical services beneath the roof were carefully isolated removed then reinstated following the roof replacement.
This approach highlights the importance of collaborative delivery models when managing RAAC remediation projects in public sector buildings.
During the programme, the scope was expanded to include refurbishment works to three additional lecture theatres.
Enhancements delivered as part of the wider university construction project included:
Replacement acoustic ceiling systems
Installation of energy-efficient LED lighting
New soft floor finishes
Full redecoration of five lecture theatres
Replacement fascia panels with low-maintenance solutions
Installation of permanent roof access ladders and ballast edge protection systems
Replacement of a structurally unsound teaching wall to enable new AV integration
Coordination with specialist contractors for seating reinstatement and new audio-visual systems
The completed works have delivered modern, compliant and structurally sound teaching spaces, enabling the University to return facilities to full operational use.
Why use a construction framework for RAAC projects?
The project was procured through Major Projects Framework 2 (MPF2), Procurement Hub’s compliant solution for delivering high-value public sector construction projects across the UK.
Using MPF2 enabled the University of Edinburgh to:
Accelerate procurement timescales
Access pre-qualified, experienced contractors
Ensure regulatory compliance
Engage delivery expertise at an early stage
Maintain cost and programme certainty
