RAAC Appraisal FAQs
An options appraisal will typically take 3-weeks, although this can vary, and includes a structural assessment, a programme to understand site conditions and work with stakeholders to determine their priorities.
Our methodology to identify the most appropriate and cost effective option is based on proprietary research conducted by RCS and its academic and engineering partners. As such, our interpretation of the data and our experience leads to a more nuanced understanding of what is possible.
As part of the appraisal we will work with you to identify key stakeholders. This could include facilities, capital projects, building managers, finance, health & safety and building users or operators.
The solution(s) will be identified using our ‘Options Appraisal’ methodology, which ranks options based on engineering data and interpretation, site conditions and stakeholder priorities.
Typically the output will include a presentation to key stakeholders and a detailed report..
RAAC Assessment FAQs
This is heavily dependent on the size of the building, the access required in order to undertake the inspection and the quantity of panels. We typically aim to inspect at least 10% of the panels to develop the engineering data required to make a risk assessment. Typically on site work is 1-2 days with data and calculations and final reporting following a week later.
The engineer leading the assessment will want to establish the bearing length ( how far the end of the panel sits on top of a wall or steel). There are several methods for determining this, which may include making a small hole. Occasionally, we may drill a small hole in a panel to determine if the metal inside is present over the bearing. This work is conducted under the supervision of our lead engineer.
The engineers follow the IStructE guidance to determine the risk classification. This includes looking for signs of water leaks (both present and past), cracking, inadequate bearing lengths, deflections, corrosion and signs of spalling (bits falling off).
RCS will work with you to understand if a risk of asbestos is possible and can support you in deciding how best to manage it.
It is very helpful to have someone that knows the history of the buildings and has keys to all areas. We will ask for any original construction drawings, asbestos reports, floorplans and any existing survey reports. We will work with you in advance to understand if any support with access is required. Depending on the use of the building we may need to restrict access when the assessment is underway.
This will be dependent on the scale of the buildings but typically reports are issued within two weeks. If needed, a verbal dynamic risk assessment will be given if the lead engineer believes an urgent safety issue exists. We will work with you to present emergency options and support you in managing the risk.

RAAC Survey FAQs
Time will be spent researching and reviewing the property in advance. Typically we will be on site for 1 day with a further day for detailing our findings in a comprehensive report
We try to avoid making any intrusions if possible. On occasion, we will need to make a small hole in plaster finished ceilings to determine what is behind the finish.
Our specialist surveying team has extensive experience in identifying RAAC. Testing is not normally required.

Typically individual reports are issued within one week. If a surveyor identifies RAAC which presents a risk you will be notified immediately and we will work with you to manage the risk and next steps.
