RAAC Assessment in Thatcham

Finding RAAC in a building in Thatcham is the start of a decision, not the end of one. The RAAC assessment is the engineering judgement that follows: a panel-by-panel classification by John Staves (CEng FIStructE, MIoD), a chartered structural engineer and one of the UK's leading specialists in RAAC, based on the survey and scanning carried out by Neil Smuts (MCIOB, MInstNDT, FRCSP), President of the UK Concrete Scanning Standard and a Fellow of the Register of Concrete Scanning Professionals, and a clear statement of what should happen next.

  • Built on survey and scanning evidence from Neil Smuts, MCIOB MInstNDT FRCSP
  • Panel-by-panel: what can stay in use, what needs propping, what needs monitoring
  • Strengthen-or-replace answered honestly, with the cost picture

What a RAAC assessment in Thatcham covers

The assessment takes the survey record for the building in Thatcham, panel by panel, and turns it into engineering conclusions. Each panel is classified on its condition, bearing, cracking, deflection and exposure to water, with reference to the current Institution of Structural Engineers guidance on RAAC. The assessment states which panels can remain in use as they are, which need propping or restricted use now, which should be monitored, and which need intervention.

It then answers the question the budget depends on: can this roof be strengthened in place, or does it need to come out? Where strengthening is viable, the assessment says so and sets out what the scheme would need to achieve.

Strengthen or replace: the question the assessment must answer

RAAC is not a single condition. Planks that have been kept dry, bear properly on their supports and show no deflection behave very differently from planks that have been wet for decades or sit on a bearing that is too short. The assessment separates the two for your building in Thatcham, and it is the difference between them that decides whether strengthening in place is on the table. 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.

Where it is, the same team designs and delivers it. Where it is not, we say so.

RAAC structural inspection and engineering inspection in Thatcham

An engineering inspection is the evidence-gathering half of the assessment: scanning for reinforcement and bearing length, measured deflection, cracking, moisture and previous repairs, panel by panel. The structural assessment is the judgement built on it: each panel placed in a risk category against the Institution of Structural Engineers guidance, the immediate actions, the monitoring position, and the strengthen-or-replace recommendation. For schools, academies, NHS estates and councils in Thatcham, the two are delivered together and signed by a Fellow of the Institution of Structural Engineers. A full engineering inspection of a large or complex building is priced per building; a visual survey, where that is all that is needed, starts from £395.

RAAC in Thatcham

We know Thatcham well: it is a town on the Kennet with large industrial estates at Colthrop and a big post-war housing stock, with post-war schools and community buildings that grew with the housing, and the industrial buildings at Colthrop, and around 25,500 residents under West Berkshire Council. Ask the RAAC assessment question of any flat-roofed building here that predates the mid 1990s, because that is where RAAC planks were used.

Where to begin if you manage property in Thatcham

The question is not "does Thatcham have RAAC" but "which of my buildings might". The answer sits in the construction dates. Buildings of the RAAC era in and around Thatcham, Newbury and Cold Ash typically include post-war schools and community buildings that grew with the housing, and the industrial buildings at Colthrop. Pull the dates for each, note which have flat roofs, and treat every one that fits as unconfirmed until a RAAC assessment says otherwise. We are happy to look at the list with you before anything is booked.

Deliverables

A written structural assessment signed by John Staves (CEng FIStructE, MIoD), a chartered structural engineer and one of the UK's leading specialists in RAAC: panel-by-panel classification against the Institution of Structural Engineers guidance, immediate actions, a monitoring and management position, and a recommendation on strengthening versus replacement with the reasoning behind it. Where the survey has not yet been done, we carry out the RAAC survey in Thatcham first and the two are delivered together.

Practicalities

We can usually be on site in Berkshire within one to two days, 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. Evening, weekend and holiday visits are no problem, which matters for occupied buildings in Thatcham. Professional indemnity insurance is held to a maximum of £10 million, with public and employers' liability arranged on a per-site basis, and every assessment is signed by a Fellow of the Institution of Structural Engineers, which is what trusts, NHS estates, insurers and funders look for.

Questions from Thatcham

RAAC assessment FAQs

How quickly can you assess a building in Thatcham?

We are based in Finchampstead, Wokingham, so we can usually be on site in Berkshire within one to two days, 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.

Will my trust, insurer or funder accept the assessment?

Every assessment is signed by a Fellow of the Institution of Structural Engineers, which is what trusts, NHS estates, insurers and funders look for. Professional indemnity insurance is held to a maximum of £10 million, with public and employers' liability arranged on a per-site basis.

What are the RAAC risk categories?

The Institution of Structural Engineers guidance places each RAAC panel in a risk category based on its condition, bearing, deflection, cracking and exposure to water, from panels needing no immediate action to panels needing action now. The assessment states the category for every panel in the building and what each category requires.

What does a RAAC structural inspection cost?

It is priced per building, because size, access and the level of detail required vary enormously; a large hospital estate and a village hall are not the same job. As a guide, a visual RAAC survey starts from £395. A full engineering inspection of a large or complex building, a hospital for example, is priced per building once we know its size, access and the level of detail required.

Who carries out the RAAC assessment?

John Staves (CEng FIStructE, MIoD), a chartered structural engineer and one of the UK's leading specialists in RAAC. He carries out all of the structural calculations and assessments for Structured Carbon.

Do I need a survey before an assessment?

Yes. The assessment is an engineering judgement on evidence, and the evidence comes from the survey. If your building in Thatcham has not been surveyed, we do that first, led by Neil Smuts, and deliver the two together.

Can you assess from someone else's survey?

Sometimes. If an existing survey records what the assessment needs, panel by panel, we can work from it. Where it does not, we will say what is missing rather than assess on thin evidence.
