Three documents get confused constantly, and the confusion costs start dates: a risk assessment, a method statement, and the combined RAMS that most of UK construction actually submits.
What each one is
A risk assessment identifies the hazards a piece of work creates, who might be harmed, how likely and how severe the harm is, what controls reduce it and what risk remains. It is an evaluation.
A method statement describes how the work will be carried out: the sequence, the equipment, the people, the stages, the make-safe at the end. It is an instruction.
A RAMS is the two bound together, cross-referenced so the controls identified in the assessment appear in the sequence they apply to. That combination is a convention rather than a legal category, and it exists because the two documents are far more useful together than apart.
What the law requires
The risk assessment is the one with a statutory basis. Regulation 3 of the Management of Health and Safety at Work Regulations 1999 requires every employer to make a suitable and sufficient assessment of the risks to their employees and to others affected by the work, and to record the significant findings where five or more people are employed.
The method statement is not named in legislation. It is how a contractor evidences the duty in CDM 2015 regulation 15 to plan, manage and monitor construction work so it is carried out without risks to health and safety so far as is reasonably practicable — and how the arrangements get communicated to the people doing the work.
So: the assessment is required by name, the method statement is required in substance, and "RAMS" is the industry's word for delivering both at once. CDM 2015 explained covers where those duties sit among everybody else's.
Which document for which work
In practice the answer is set by three things: the risk of the activity, whether the sequence matters, and what the principal contractor's own requirements say. The last of those overrides the first two — if the site requires a full RAMS for every package, that is the answer regardless of what the work would otherwise justify.
| Type of work | Usually appropriate | Why |
|---|---|---|
| Low-risk maintenance in an unoccupied area | Standalone risk assessment | The hazards need assessing; the sequence is not what keeps anyone safe. |
| Repetitive work your team does identically every time | Risk assessment plus a standing safe system of work | The method is already established and documented; the assessment is what changes per site. |
| A defined task with a critical order of operations | Full RAMS | Sequence is a control — doing stage three before stage two is the hazard. |
| Work at height, excavation, confined space, hot works, demolition | Full RAMS | High-consequence work where controls, competence and rescue all have to be stated together. |
| Lifting operations | Full RAMS plus a lift plan | LOLER requires the operation to be planned by a competent person; the lift plan sits alongside the RAMS. |
| A design or engineering procedure with no site-specific risk | Standalone method statement | The document exists to specify how something is done, not to assess site hazards. |
| Anything on a site whose rules require it | Whatever the construction phase plan specifies | The principal contractor coordinates the site and sets the format. |
Where the row says "full RAMS", submitting a method statement alone is the classic cause of a rejected package — it describes the work without ever stating what could go wrong or what stops it.
What principal contractors typically ask for
On most commercial projects: a full RAMS per work package, submitted a fixed number of days before the activity starts, on the site's own template or matching its section order. Larger contractors add specific requirements — a lift plan for any lifting operation, a permit application referenced in the method, a temporary works design reference for anything that needs one.
They are reading it for compatibility with everything else on site as much as for internal quality, which is why the format request is not bureaucracy: a document in the expected order can be checked against nine others quickly. What a principal contractor looks for covers the order they read in.
And the document above all three
None of these is the construction phase plan. That is a site-wide document required by CDM 2015 regulation 12, prepared by the principal contractor — or by the contractor where there is only one — before the construction phase begins. Submitting a RAMS when a plan was requested, or the reverse, is a week lost. Construction phase plan versus RAMS sets out the boundary.
Reviewing all three
If you are on the receiving end of these documents, the checks differ by type: a standalone risk assessment has no method to cross-check against, and a standalone method statement has no residual risk to look for, so reading either as though it were a RAMS produces findings that are not useful.
That distinction is reflected in how Valify handles them. RAMS review is on every plan including the trial; standalone method statements and standalone risk assessments are covered on Growth and above, reviewed against the checks appropriate to each rather than against the full fifteen-section RAMS structure. Which documents can be reviewed sets out what each plan covers.
Whichever you are producing, the failure is the same one: a document that describes a category of work rather than this job. Generic versus site-specific RAMS applies to all three.
