What principal contractors check in a RAMS

When a principal contractor reviews a RAMS they are checking whether this document shows that this job, on their site, with these people and this equipment, will be done safely and in line with their construction phase plan. In practice that is a short list of checks: site-specific details, a sequence that deals with every hazard, evidence of competence and equipment inspection, permits, emergency arrangements and sign-off. A RAMS that fails any of them is returned before work can start.

Key facts

  • A principal contractor must plan, manage, monitor and coordinate the construction phase, and make sure contractors follow the construction phase plan where required (CDM 2015 regulation 13). Reviewing RAMS is one of the main ways they do it.
  • Contractors must comply with the principal contractor's directions and the parts of the construction phase plan relevant to their work (regulation 15).
  • Acceptance does not transfer responsibility. The contractor who wrote the RAMS remains responsible for planning and managing their own work.
  • Most rejections are for missing specifics, such as the site address, dates, named supervisor or actual access method, rather than for missing hazards.
  • Lifting equipment for lifting people, and lifting accessories, need a thorough examination at least every 6 months; other lifting equipment at least every 12 months, unless a written examination scheme sets different intervals (LOLER regulation 9).

Why your RAMS is reviewed

Under CDM 2015 the principal contractor must plan, manage, monitor and coordinate the construction phase so that work is carried out without risks to health or safety, organise cooperation between contractors and coordinate how they meet their legal duties. Each contractor, in turn, must follow the principal contractor's directions and the parts of the construction phase plan that apply to their work. The RAMS is where those two duties meet: it shows the principal contractor how your work will be done, and lets them check it fits the site, the programme and the other trades.

Clients and facilities managers on non-construction sites do the same thing for a similar reason. Where two or more employers share a workplace, even temporarily, the Management of Health and Safety at Work Regulations 1999 require them to cooperate and coordinate their arrangements, and reviewing a visiting contractor's RAMS is how most organisations do that.

The review checklist

Reviewers work from a list, whether it is written down or not. These are the checks, and the most common reasons each one fails.

CheckWhat the reviewer looks forWhy it gets sent back
Document controlReference, revision number, date of issue, preparer and approver, review dateUnsigned, undated, or a revision that does not match the copy the site holds
Scope and siteThe site address, the work area, dates and working hours"Various locations", the wrong site, or a scope that does not match the order
Sequence of worksNumbered steps in the real order, including isolation, permits and inspections"Install to manufacturer's instructions" as the whole method
Hazards and controlsEach significant hazard with who could be harmed, the controls and the residual riskControls that never appear in the sequence, or "wear PPE" as the only control
Access and work at heightThe actual access equipment, why it was chosen, inspection and rescueA ladder by default, or a harness with no rescue plan
CompetenceNamed operatives and the cards they hold: CSCS, ECS, IPAF, PASMA, CISRS, Gas Safe, SSSTS or SMSTS for supervisors"All operatives are competent" with nothing to show it
Plant and equipmentWhat is used, and its inspection and thorough examination statusNo LOLER reports for lifting equipment, no inspection records for towers or scaffolds
Hazardous substancesCOSHH assessments for the products used and the dust or fume producedSafety data sheets attached instead of assessments
PermitsHot works, electrical isolation, confined space and permit to dig, as the site operates themNo mention of a permit the site rules require
Emergency arrangementsFirst aider, site emergency contact, nearest A&E, fire procedure, assembly point, rescue"Call 999" as the whole plan
InterfacesOther trades, building occupants, the public, deliveries and segregationNothing about working in an occupied building
Briefing and sign-offAn operative briefing record to be signed before work startsNo briefing record, or one signed by people not on the job

The evidence that goes with it

Most principal contractors ask for supporting documents with the RAMS, or at induction. Having them ready shortens the review.

  • Training and competence cards for each operative, and supervisor qualifications
  • Thorough examination reports for lifting equipment: at least every 6 months for equipment that lifts people and for lifting accessories, at least every 12 months for other lifting equipment, or as a written examination scheme sets
  • Inspection records for work equipment, towers, scaffolds and MEWPs
  • A lifting plan for any lifting operation: LOLER requires every lift to be properly planned by a competent person, appropriately supervised and carried out safely
  • COSHH assessments for the substances used and produced
  • Employers' liability insurance, which by law must be for at least £5 million where you have employees, and public liability insurance to the level in the contract
  • Asbestos awareness training for trades that could disturb asbestos in older buildings

How to get it accepted first time

Most resubmissions are avoidable. The contractors whose RAMS go through first time tend to follow the same routine.

  1. 1Read the pre-construction information, the site rules and the relevant parts of the construction phase plan before writing anything.
  2. 2Visit the site, or get photographs and drawings, so the access, work area and interfaces are real rather than assumed.
  3. 3Use the principal contractor's own format or headings if they have one.
  4. 4Name the supervisor and operatives, and the cards and qualifications each holds.
  5. 5Check that every hazard in the risk assessment appears as a control, check or permit in the sequence of works.
  6. 6Use the site's own names for its permits, and say who issues each one and when.
  7. 7Include a rescue plan for any work at height, and site-specific emergency arrangements.
  8. 8Attach the evidence pack, and issue the document with a revision number and date.

When it comes back with comments

Answer every comment, revise the document, raise the revision number and resubmit, noting what changed. If the comment reflects something about the site you did not know, it is information the RAMS needed anyway.

Where a site rule conflicts with your method, the site rule wins on that site: change the method, or agree the alternative with the principal contractor in writing before work starts. If the job has already begun, brief the revised RAMS to the operatives before they carry on, and have them sign the new briefing record.
