Site Monitoring

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

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

There are 3 mechanisms available to support effective site monitoring:

1.  A formal site review visit by the CLOCS monitoring team.

This provides a site score, and a detailed report capturing good practice and recommendations for improvement. The site team will be asked to complete a self-assessment form and submit it to the CLOCS monitoring team prior to the visit. Formal site review reports and scores can be used to evidence, both internally and externally that CLOCS requirements are being met.

2.  An advisory site review visit by the CLOCS monitoring team.

This provides a detailed report capturing good practice and recommendations for improvement but will not include a formal score or compliance rating.

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.


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 all 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:
