Review subcontractor RAMS against the actual scope, site conditions, construction phase plan, interfaces and emergency arrangements. Check that the method is clear enough to brief, the controls are specific enough to implement, and the subcontractor has the skills, equipment and supervision needed for the work. Record questions and the outcome: revise and resubmit, accepted with actions, or ready to progress to site pre-start checks. A document review is not a site inspection and it is not a guarantee that the work is safe.

This guide covers England, Scotland and Wales; Northern Ireland has separate CDM 2016 rules. See HSENI's CDM 2016 guidance if the work takes place there.

Who should review a subcontractor RAMS?

The review should be done by someone who understands the work, the site and the risks involved. On a project with more than one contractor, the principal contractor must plan, manage, monitor and coordinate the construction phase and check that appointed people have the relevant skills, knowledge, experience and organisational capability. The reviewer may be a site manager, supervisor, competent health and safety person or another nominated reviewer, depending on the job.

Stage 1: Check the document against the job

Start with the scope and project information. A RAMS can be well formatted and still be for the wrong site or a different method.

  • Project identity: site address, work area, client or principal contractor, subcontractor, task owner, revision, dates and contact details are correct.
  • Scope and boundaries: the document says exactly what the subcontractor will do, where it starts and ends, what it excludes and what another trade must provide.
  • Site information: access, deliveries, work area, nearby occupants or public, existing structures, overhead and underground services, welfare, lighting, noise and other site constraints are considered.
  • Interfaces: the sequence is coordinated with other trades, traffic routes, lifting, temporary works, isolations and any construction phase plan or site rules that apply.

If the RAMS names a different address, relies on a drawing not supplied, or assumes an access route that is not available, return it before debating the risk matrix. Fixing the project facts first prevents the rest of the document giving false confidence.

Stage 2: Check the risk assessment and controls

Read each significant hazard with the method beside it. The controls should be practical actions someone can see, supervise and maintain, rather than “take care” or “use appropriate PPE”. Check:

  • ☐ The hazards match the task, location, people affected and project information.
  • ☐ The assessment covers public, neighbours, occupants, other contractors and workers who may be exposed indirectly.
  • ☐ Controls follow a sensible hierarchy: remove or reduce the hazard first, then use engineering and organisational controls before relying on PPE.
  • ☐ The method statement actually describes how the controls will be applied in sequence.
  • ☐ Plant, tools, substances, lifting, access, work at height, excavation, temporary works, fire, emergency and environmental controls are covered where relevant.
  • ☐ Permits, isolations, service information, COSHH assessments, safety data sheets, inspection certificates and design information are identified where the task needs them.
  • ☐ Residual risks are credible and do not become “low” simply because PPE was added.
  • ☐ The RAMS says what changes require a review and who can stop or alter the work.

Ask a simple test: could a supervisor use this document to brief the team and observe the method on the ground? If the answer is no, record the precise clarification needed. Do not accept a generic paragraph about working at height when the job depends on a specific scaffold, MEWP, rescue plan and exclusion zone.

Stage 3: Check competence, resources and briefing

The RAMS should name the people responsible for the work and supervision, but a name alone is not evidence of competence. Check the project's requirements for trade qualifications, plant authorisations, specialist training, experience, equipment and supervision. Ask for the evidence that is proportionate to the risk and retain it in the agreed project system.

Before work starts, confirm the people doing the task will receive a site-specific briefing and can ask questions. The RAMS should be available where the work takes place, in a form workers can understand. Plan a re-brief when the method, people, site or conditions change. HSE's principal contractor guidance also requires suitable site inductions and further information or training for workers.

Stage 4: Verify on site before authorising the task

A RAMS review is a document gate. Complete the physical pre-start checks separately:

  • ☐ The work area matches the information reviewed.
  • ☐ Access, exclusion zones, edge protection, welfare and emergency arrangements are in place.
  • ☐ The specified plant, equipment, materials, controls and competent supervision are present.
  • ☐ Permits, isolations, service marks, inspections or handover certificates required by the task are complete.
  • ☐ Other contractors know about the work and the planned interfaces are controlled.
  • ☐ The team has been briefed, understood the method and knows who can stop the job.

RAMS review outcomes to record

Use a small set of outcomes so the next person can see what happened:

  1. Revise and resubmit: a significant gap, conflict or missing control means the task is not ready for pre-start checks.
  2. Accepted with actions: the document can move forward only when named actions are closed by the agreed date; make the start condition explicit.
  3. Ready to progress to pre-start: the document review is complete, with physical checks and authorisation still required.
  4. Rejected for this scope: the proposed method cannot be made suitable without a fundamentally different plan or competent specialist input.

Record reviewer, date, revision, comments, action owner, due date and close-out evidence. Keep the decision with the RAMS so a superseded version cannot be mistaken for the current one.

Keep your own project documents ready

If you are producing RAMS for your own work, The Site Book can create site-specific RAMS, CPPs, inductions and related paperwork from your project details. Pro includes document quality checking, permits and site diary tools; Business adds internal team access and site files for sharing project information. Review every generated document against the actual work and have a competent person make the start decision. Create a free job pack for one real project.

Common questions

Does the principal contractor approve every RAMS?

Project arrangements and contracts vary. Where RAMS are submitted, the principal contractor should have arrangements to review them and coordinate the work. A review does not transfer the subcontractor’s duties or create a universal legal approval form.

Can I accept a subcontractor’s generic RAMS?

Do not accept it just because the task name looks right. Require the document to reflect the actual site, scope, people, equipment, interfaces and emergency arrangements. A template can be a starting point; it is not site-specific evidence by itself.

Who is responsible if the RAMS is wrong?

Responsibilities depend on the project roles, appointment and work. The principal contractor must manage and coordinate the construction phase; the contractor must plan, manage and monitor work under its control. Get competent advice where duties or risks are unclear.

What a RAMS review does — and does not decide

Pros

  • Checks the document against the actual scope, site, interfaces and construction phase plan.
  • Records precise questions, actions, owners, dates and the current document revision.
  • Creates a clear gate before separate site pre-start checks and authorisation.

Cons

  • A well-formatted RAMS can still describe the wrong site or an unavailable method.
  • Document review does not prove the specified controls are present on site.
  • Review does not transfer the subcontractor’s duties or guarantee that work is safe.
