As the information you have requested is 'environmental information' for the purposes of the Environmental Information (Scotland) Regulations 2004 (EIRs), we are required to deal with your request under those Regulations. We are applying the exemption at section 39(2) of the Freedom of Information (Scotland) Act 2002 (FOISA), so that we do not also have to deal with your request under FOISA.
This exemption is subject to the 'public interest test'. Therefore, taking account of all the circumstances of this case, we have considered if the public interest in disclosing the information outweighs the public interest in applying the exemption. We have found that, on balance, the public interest lies in favour of upholding the exemption, because there is no public interest in dealing with the same request under two different regimes. This is essentially a technical point and has no material effect on the outcome of your request.
The contract for the Design, Build, Finance and Operation of the M8 M73 M74 Improvements Project was awarded to Scottish Roads Partnership (SRP) in February 2014. As such, SRP is responsible for the funding, final design, construction and subsequent maintenance of the completed scheme for a period of 30 years on behalf of the Scottish Ministers. Turning now to your request.
Q1 – Schedule 4 of the M8 M73 M74 Motorway Improvements Project Contract lays out the requirements for Operations and Maintenance on the project roads. SRP is required to undertake safety inspections every 7 days and undertake safety patrols every 7 days midway between safety inspections. SRP advise that safety inspections for that stretch of road are generally carried out every Tuesday with safety patrols being undertaken every Friday. These inspections are conducted by competent personnel surveying the carriageway for safety defects in a vehicle driving as slow as possible for the stretch of road.
