RAAC Survey in Slough

Inside a Structured Carbon RAAC survey

A RAAC survey has three jobs: confirm whether RAAC is present, record the condition of every panel, and gather the measurements an engineer needs to assess it. We do all three in one visit where access allows. Non-destructive scanning identifies RAAC and the position of its reinforcement without cutting into the roof, and a panel-by-panel inspection records bearings, cracking, deflection, moisture and past repairs against a location plan.

The report goes straight to John Staves (CEng FIStructE, MIoD), a chartered structural engineer and one of the UK's leading specialists in RAAC, so the survey is planned around the questions his assessment has to answer rather than around a generic checklist.

School, academy, NHS and council RAAC surveys in Slough

Most RAAC surveys we are asked for in Slough come from four places: schools and academy trusts working to Department for Education guidance, NHS and primary care estates teams, council property departments, and the owners of halls, churches, sports centres and offices with flat roofs from the 1950s to the mid 1990s. Each gets the same two-part offer. A visual survey, from £395, identifies and records the RAAC. An engineering inspection and structural assessment, priced per building, classifies every panel and tells you what to do, signed by a Fellow of the Institution of Structural Engineers.

For a school or academy trust that needs a RAAC surveyor who can also provide a management and remediation strategy after the inspection, that is what the two-part offer is for.

Prioritising buildings in Slough

Not every building in Slough needs a RAAC survey, and we would rather tell you that than sell you one. The ones that do are flat-roofed, date from the 1950s to the mid 1990s, and have never had RAAC confirmed or excluded by scanning. Under Slough Borough Council that generally means post-war schools, industrial sheds and civic buildings built at pace through the 1950s to 1980s. Ranked by occupancy and by the consequence of a failure, that list usually puts schools, health buildings and places of assembly first, then offices and industrial units.

The practical questions, answered

How soon: we can usually be on site in Berkshire within one to two days. How long: the report follows within five working days of the site visit, depending on the size of the survey and the level of detail required. When: evening, weekend and holiday visits are no problem. With what: GSSI Flex NX and GSSI StructureScan Mini ground penetrating radar, Proceq GP8800 and GP8100 radar, the Proceq Pundit PD8050 ultrasonic tomograph, and other electromagnetic and ultrasonic NDT instruments. How much experience: we have surveyed thousands of square metres of RAAC. Insured: professional indemnity insurance is held to a maximum of £10 million, with public and employers' liability arranged on a per-site basis. Where: Berkshire, Hampshire, Surrey, Oxfordshire and Buckinghamshire are local to us, and we work across the UK, and Slough is on our doorstep.
