Winter maintenance inspection policy including inspection regimes and intervention thresholds: EIR release

“1. Please send an electronic copy or link to a published source of your authority's most recent highways maintenance inspection policy which covers, for all road, footway and cycleway hierarchies:

• inspection regimes;
• intervention thresholds and associated response times to rectify defects;
• winter maintenance policies

2. If that policy was published after 28/10/2016 could you also provide:

• the previous equivalent policy.

Any report to councillors proposing and explaining the changes from the previous version to the current version.”

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.

Please see below the definition as per the 4th Generation Term Contract for management and maintenance of the Scottish Trunk Road Network. This definition also explains the associated response times to rectify defects. 

"Category 1 Defect" means a Defect that necessitates prompt attention because it presents:

(i) an immediate or imminent hazard, or

(ii) a risk of rapid structural deterioration to the affected element. 

"Category 2 Defect" means any Defect which is not a Category 1 Defect.”

In addition, the following extract is taken from Schedule 7 Part 1 of the 4th Generation Term Contract for Management and Maintenance of the Scottish Trunk Road Network:

“2. DEFECT CATEGORIES AND RESPONSE TIMES

2.1 Classification of Category 1 and Category 2 Defects.

2.1.1 When classifying Category 1 and Category 2 Defects, the Operating Company shall give consideration to the potential impact on all road users including motorists, pedestrians, cyclists, motorcyclists, equestrians and disabled users.

2.1.2 The Operating Company shall comply with the provisions of the Transport Scotland Trunk Road Inspection Manual regarding classification of Defects.

2.1.3 The Transport Scotland Trunk Road Inspection Manual is deemed not to contain an exhaustive compendium of Defects. In the absence of a description of a Defect in the Transport Scotland Trunk Road Inspection Manual, the Operating Company shall make the classification from first principles.”

The following extract is taken from Schedule 7, Part 1 of the 4th Generation Term Contract for management and maintenance of the Scottish Trunk Road Network and details the timescales for repairing defects:

“2.2 Category 1 Defects Response Times.

2.2.1 Unless stated otherwise in this Part, Category 1 Defects shall be dealt with by the Operating Company in priority order as stated in paragraph 2.2 of this Part.

2.2.2 The Operating Company's inspection team or initial Incident Response Resources shall make the Category 1 Defect safe when identified. This shall be through executing immediate repairs, removing the hazard or by taking any other measures necessary to protect the public and other users of the Unit.

2.2.3 Where a Category 1 Defect renders a Trunk Road unsafe for road users, the Operating Company shall, under Police instruction or on receipt of an appropriate Order, close the relevant part of the Trunk Road for as short a period as possible while remedial action is undertaken.

2.2.4 Where a Category 1 Defect cannot be repaired immediately or the hazard cannot be removed, the Operating Company shall take action to make the area safe until the required temporary or permanent repairs have been completed.

2.2.5 The temporary or permanent repairs shall be undertaken as soon as possible and no later than:

(i) 06:00 on the day following identification for Category 1 Defects on carriageways, and

(ii) within 24 hours of identification for all other Category 1 Defects.

2.2.6 Where a temporary repair has been carried out, the deferred permanent repair period for the following Defect types shall be:

(i) 28 days for carriageway surface, and

(ii) 56 days for Bridge parapets. 

2.2.7 All other Category 1 Defects shall be repaired permanently within the specific period referred to in this Part, or no later than 28 days after identification where no specific period is stated.”

Question 2 – the arrangements above will continue until the next contract renewal dates.
