Site Monitoring

Monitoring compliance of site operations and fleet operations against the CLOCS Standard is critical to ensure all parties consistently meet that national standard and, where necessary, take appropriate constructive action where an organisation falls short of that standard to prevent recurrence.

There are two key elements of monitoring for CLOCS compliance:

  1. By the Site Access Traffic Marshals – monitoring compliance of fleet operations servicing the construction site
  2. By the independent CLOCS Site Monitoring Team – reviewing compliance of site operations against the CLOCS Standard

Site Access Traffic Marshals

Site Access Traffic Marshals stationed at the site entrance are the primary and critical interface between the site, fleet operations and the public. They are vital in ensuring only authorised vehicles and people enter the site, vital in ensuring vehicles entering and leaving the site do so safely and efficiently, and are often the main human interaction between site activities and the public.

Competent Site Access Traffic Marshals are recognised by progressive contractors as essential to help maximise productivity of the site and the drivers of the vehicles delivering products/plant or removing waste material. Most sites also have Banksmen who guide vehicles once within the site hoardings – these are distinct roles and cannot be done concurrently by the same person (as can’t be in two places at once!), though often personnel are rotated between roles.

CLOCS-approved SATM training available:

  • There are many organisations offering traffic marshal training, but the quality is often described as ‘varied’.
  • At present (Dec ’19), no organisations have been approved by CLOCS to deliver Site Access Traffic Marshal training meeting the SATM - Competency Framework Final.pdf.
  • Discussions and reviews of existing training providers keen to be CLOCS-approved are in progress and should be approved and published on this website in January ’20.
  • If you wish to become CLOCS-approved to deliver this training, please contact support@CLOCS.org.uk. You will be required to provide detailed evidence of your proposed training delivery, quality management systems and past performance as the basis of assessment by the CLOCS team. CLOCS SATM TP approval requirement and process.pdf. Once approved, all providers will be listed below.

CLOCS is also looking to provide Train-the-Trainer training to enable companies to deliver their own SATM training against this framework and be CLOCS-approved to deliver in-house training (where its quality is maintained). Please contact support@CLOCS.org.uk


CLOCS Site monitoring

The CLOCS Standard v3 requires effective monitoring of site compliance.

To help Champions understand and improve site compliance and consequent safety, CLOCS Site Monitoring has been developed in partnership with CLOCS partners Considerate Constructors Scheme (CCS).

A CLOCS Champion commits to having:

  • at least 20% of its sites formerly reviewed by the CLOCS team
  • a clear plan to get the majority of its sites to be CLOCS compliant within two years
  • a clear plan to encourage other organisations to adopt the CLOCS Standard

There are 3 mechanisms available to support effective site monitoring:

1.  A formal site review visit* by the CLOCS team, together with submission of ‘self-assessment’ form.  This provides:

  • a site score, and
  • a detailed report capturing good practice and recommendations for improvement. 

CLOCS Champions are required to have at least 20% of sites assessed by the CLOCS site monitoring team. Formal site review reports and scores can be used to evidence that this requirement is being met.

2.  An advisory site review visit* by the CLOCS team + self-assessment checklist: this provides:

  • a detailed report capturing good practice and recommendations for improvement.

NB:  An advisory site review visit does not contribute to the 20% requirement for sites to be formally monitored.

3.  Self-assessment checklist

The self-assessment checklist reflects the requirements of the CLOCS Standard, as they apply to the site. The questions look to establish compliance and capture performance beyond minimum requirements as they seek detail on all elements described as - mandatory (designated by ‘shall’ within the Standard), recommended and optional (designated by ‘should’ and ‘may’).  This checklist helps principal contractors to understand their level of compliance.

  • The checklist must be completed and submitted to the CLOCS team in advance of a CLOCS site review visit. A form will be issued when you book your visit.
  • can be used as evidence for the CLOCS team that an organisation is working towards corporate compliance (as set out in the Implementation Communication Plan)

NB:  Self-assessment does not contribute to the 20% requirement for sites to be formally monitored.

As well as looking to establish whether the Standard is being met, the assessment and monitoring process aims to recognise best practice and raise standards across the industry. The CLOCS site monitoring team provides a detailed report containing helpful advice on areas for improvement and provides scores in 11 key areas.  Overall scores and reports can be used as:

  • evidence of compliance to your clients
  • a benchmark for future employers/clients
  • internal performance review

Importantly effective monitoring will identify areas of underachievement that can be quickly addressed.


The following documents are available to help champions understand and get the greatest value from the process:
