RAAC Survey in Shinfield
If you manage a school, hall, clinic, leisure centre or office in Shinfield with a flat roof built between the 1950s and the mid 1990s, a RAAC survey is how you find out whether reinforced autoclaved aerated concrete is in it and how it is performing. Our surveys are led by Neil Smuts (MCIOB, MInstNDT, FRCSP), President of the UK Concrete Scanning Standard and a Fellow of the Register of Concrete Scanning Professionals, working from Finchampstead on the other side of Wokingham.

Based in Finchampstead, Wokingham. Shinfield is local to us.
How we survey RAAC in Shinfield
We start with the building's history: when it was built, when it was extended, and any drawings or previous reports you hold. On site we inspect every accessible roof, floor and wall panel that could be RAAC, record its condition, and use non-destructive scanning to confirm whether a panel is RAAC and where its reinforcement sits. Bearings are checked, because RAAC planks fail at the ends before they fail in the middle. We record cracking, deflection, water staining and any evidence of previous repair, panel by panel, with a location plan so nothing is lost between survey and assessment.
What you get back is a report written for a structural engineer to act on, not a photo album. Because that engineer is John Staves (CEng FIStructE, MIoD), a chartered structural engineer and one of the UK's leading specialists in RAAC, the survey is designed around what he needs to classify each panel and decide what should happen next.
Do you need a RAAC survey?
A RAAC survey is usually prompted by one of four things: guidance from the Department for Education, NHS or a professional body; an insurer, lender or purchaser asking for confirmation; a planned refurbishment or extension; or something visible, such as a sagging ceiling, cracking or water staining, that has made someone nervous. All four are good reasons. For a building of the right age in Shinfield, the cost of not knowing is far higher than the cost of the survey.
RAAC surveyor for schools, academies and public buildings in Shinfield
School and academy RAAC surveys are most of our work. Headteachers, school business managers and multi-academy trusts in Shinfield need a RAAC survey that is quick to arrange, quiet to carry out and written so that the trust, the Department for Education and the insurer can act on it. The same applies to NHS estates, GP surgeries, council property teams, churches and village halls, leisure centres and commercial landlords: anyone with a flat-roofed building of the RAAC era.
Which school RAAC surveyors can also provide a management and remediation strategy following inspection? We can, because the surveyor and the chartered engineer who assesses the findings are one team, and the strengthening that follows is designed by the same engineer. A visual survey starts from £395; a full engineering inspection is priced per building.
RAAC in Shinfield
Around 5,400 people live in Shinfield, the Shinfield Studios film complex and the University of Reading science park sit within a parish of sustained housing growth. It falls under Wokingham Borough Council, and it carries older village buildings and schools next to a great deal of new construction. Frimley Park Hospital, which serves this part of Berkshire, is a publicly identified RAAC hospital and is being replaced under the New Hospital Programme, which has put RAAC on the agenda for every estates team in the area. If a building in Shinfield has a flat roof and dates from the 1950s to the mid 1990s, RAAC should be ruled in or out rather than assumed absent.
RAAC survey: how to get started in Shinfield
Three pieces of information get a RAAC survey in Shinfield moving: the age of the building, the type of roof, and any drawings or previous reports you hold. With those we can say whether the building is a realistic RAAC candidate, what the visit would involve, and how long it would take. For estates spread across Shinfield, Reading and Spencers Wood, we plan the visits as one programme so that nothing is missed and nothing is surveyed twice.
From survey to decision
A survey on its own does not tell you what to do. That is the job of the RAAC assessment, carried out by John Staves (CEng FIStructE, MIoD), a chartered structural engineer and one of the UK's leading specialists in RAAC from our survey findings. The assessment sets out which panels are safe to keep in use, which need propping or monitoring, and whether strengthening in place is a realistic alternative to replacing the roof. Across the RAAC tenders we cost, a bespoke CFRP scheme engineered for that exact roof frequently comes in at well below 15 per cent of the cost of full replacement. On one tender, a roof costed at around £40 million to replace was priced for strengthening at under £4 million.
Because survey, assessment, design, manufacture, installation and monitoring all sit inside one partnership, nothing is lost between stages and nobody is selling you a replacement roof you may not need.
What we bring to Shinfield
We have surveyed thousands of square metres of RAAC, using 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. We can usually be on site in Berkshire within one to two days, evening, weekend and holiday visits are no problem, and the report follows within five working days of the site visit, depending on the size of the survey and the level of detail required. Professional indemnity insurance is held to a maximum of £10 million, with public and employers' liability arranged on a per-site basis.

RAAC survey FAQs
Do you need to open up the roof?
No. We confirm RAAC and locate its reinforcement using non-destructive scanning from the underside or the roof surface. Where a small opening is already present we will use it, but the survey does not depend on cutting into the building.
What equipment do you use?
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. We have surveyed thousands of square metres of RAAC with them.
Are you insured?
Professional indemnity insurance is held to a maximum of £10 million, with public and employers' liability arranged on a per-site basis.
Can the building stay open during the survey?
Yes. The survey is quiet, non-destructive work carried out room by room. Schools in Shinfield usually ask us to work around the timetable or in holidays; health and office buildings carry on around us. Neil is DBS checked.
What does the report contain?
A panel-by-panel record of what was found: whether the panel is RAAC, its condition, bearing details, cracking, deflection, moisture, previous repairs, all referenced to a location plan with photographs. It is written for a structural engineer to assess from.
Who assesses the findings?
John Staves (CEng FIStructE, MIoD), a chartered structural engineer and one of the UK's leading specialists in RAAC, carries out the structural assessment. The survey is designed around what he needs, which is why the two stages work as one.
Is a RAAC survey the same as a RAAC assessment?
No. The survey establishes what is there and what condition it is in. The assessment is the engineering judgement about what that means and what to do. We offer both, and you can read about RAAC assessment in Shinfield separately.
