PILOT works on five council properties affected by reinforced autoclaved aerated concrete (RAAC) could be set to go ahead in Dundee, if councillors approve a tender next week.

Dundee City Council’s neighbourhood regeneration, housing, and estate management committee will be asked next week to agree that Morrison Construction carry out the remedial works.

The housing service has identified five empty properties of different types across the city affected by RAAC as the test bed for solutions to the issues caused by the material.

Kevin Cordell, committee convener, said, “We want to be able to implement and test a practical, economic solution for each house-type in the council stock that contains RAAC and to establish suitability for possible future roll out across all our affected properties.
“This tender allows us to move towards that with an experienced contractor who will work with the council’s in-house design team to share knowledge and find the most practical and best value solution.”

If the committee approves the tender, the pilot remediation will involve installing a new roof structure directly below the existing one so that the RAAC is fully supported and therefore at no future structural risk.

In addition to the pilot project, the RAAC in communal areas of five properties in Menzieshill, currently in a poor condition, will have their redundant roof-mounted water tanks decommissioned and the RAAC permanently remediated using the same method.

The work, costing a total of £500,000 is expected to start in June, and be completed later in the summer.
