CDM 2015 Duty-Holder Advisory That Closes Compliance Gaps Before Inspection
A CMIOSH-chartered advisor authors or reviews your pre-construction information, construction phase plan, and sub-contractor competency record against the actual site conditions. Guaranteed 48-hour mobilisation, in writing.
What we advise on
The Three CDM 2015 Duty-Holder Scopes We Cover
The same chartered advisor often carries all three forward on a single project, which closes the coordination gap that opens up when separate consultants run each duty.
Principal Designer Duty-Holder Advisory
We work alongside the design team in pre-construction, drive hazard elimination upstream, and author the pre-construction information pack the principal contractor inherits at mobilisation.
- Regulation 9 design-stage hazard elimination
- Pre-construction information pack authoring
- Design team briefings and coordination
Principal Contractor Duty-Holder Advisory
We author or review the construction phase plan against the live site conditions, verify it answers the pre-construction information, and brief the principal contractor on Regulation 12 obligations before mobilisation.
- Construction phase plan authoring or review
- Site coordination against the live programme
- Welfare and emergency arrangements sign-off
Sub-Contractor Competency & Coordination
We verify the competency of every sub-contractor before they mobilise, fold their RAMS into the construction phase plan, and run the coordination record that satisfies CDM 2015 and stands up at HSE inspection.
- Sub-contractor competency verification
- RAMS integration into the phase plan
- Duty-holder coordination audit trail
How the engagement runs
From Duty-Holder Review To Audit-Ready Coordination
A four-step engagement that starts where your duty-holder obligations sit today and finishes with a corrective action register the HSE will recognise.
Duty-holder review
We confirm your duty-holder role under CDM 2015. You may be the client, the principal designer, the principal contractor, or a designer, and each role carries different obligations at this stage of the project. Scope is agreed before any document work starts.
Pre-construction information audit
We audit the pre-construction information against Regulation 4 and Schedule 1, fill the gaps with a site-specific pack, and hand it forward to the principal contractor in a form that drives the construction phase plan.
Construction phase plan review or authoring
We author the construction phase plan from your site programme or review the one you hold. Sub-contractor RAMS feed into the plan, and we issue a written sign-off before site mobilisation.
Ongoing duty-holder coordination
A chartered advisor keeps the duty-holder coordination record live through construction, runs a corrective action register, and updates the phase plan when site conditions change. The record becomes the audit trail when the HSE arrives.
Where CDM advisory fails
The Four Failure Points We See Most On UK And Irish Sites
Every one of these has been closed on a live project by one of our chartered advisors.
- Pre-construction information lands late from the client team, which forces the principal contractor to build a construction phase plan against incomplete hazard data.
- Construction phase plans pulled from a template library that the HSE has seen before, with no link to the site-specific risks listed in the pre-construction information.
- Sub-contractor competency taken on trust at induction, with no documented verification against the work they are about to carry out.
- No duty-holder coordination record, so when the HSE arrives there is no audit trail showing how the principal designer and principal contractor handed information across.

Where CDM Advisory Sits In The Safety Consulting Stack
CDM 2015 is the UK-side duty-holder regime, paired with PSCS advisory on the Irish side under the Construction Regulations 2013. Projects crossing the Irish Sea typically need both running in parallel, including the PSDP design-stage role.
PSCS & PSDP Advisory
The Irish-jurisdiction sibling to CDM 2015. Project Supervisor Construction Stage and Project Supervisor Design Process appointments under the Construction Regulations 2013.
Safety Policy Development
Site-specific RAMS, Method Statements, and Safe Systems of Work that drop into your construction phase plan instead of sitting alongside it.

Questions safety managers ask
CDM 2015 Advisory Questions Answered
Who needs CDM 2015 duty-holder advisory?
Anyone appointed as a principal designer or principal contractor on a construction project in the UK that meets the CDM 2015 notification thresholds. Clients with limited in-house safety capability also use a CDM advisor to satisfy their own duty to provide pre-construction information and verify duty-holder competency. We advise on appointment, sit alongside the duty-holder for the life of the project, and produce an audit trail that holds up at HSE inspection.
What is the difference between principal designer and principal contractor advisory?
Principal designer advisory runs in the pre-construction phase. We support hazard elimination in design, author the pre-construction information pack, and brief the design team on Regulation 9 obligations. Principal contractor advisory runs through construction. We review or author the construction phase plan, embed competency checks on sub-contractors, and coordinate site safety against the live programme. The same chartered advisor often carries both roles forward on a single project.
What does a construction phase plan review actually cover?
Our construction phase plan review checks the plan against the principal contractor duties in CDM 2015 Regulation 12 and Schedule 3. We verify that the significant risks identified in the pre-construction information have been addressed, that high-risk activities have site-specific control measures, that emergency arrangements match the actual site conditions, and that sub-contractor RAMS feed into the plan rather than sit alongside it. You receive a written report with a prioritised action list before site mobilisation.
Do you advise on both UK CDM 2015 and the Irish Construction Regulations?
Yes. Many of our clients run projects across both jurisdictions. We advise on CDM 2015 in the UK and on the Safety, Health and Welfare at Work (Construction) Regulations 2013 in Ireland, including PSCS and PSDP appointments. Our chartered advisors hold current standing in both frameworks, which avoids the duty-holder gap that often appears when a UK contractor mobilises onto an Irish site or vice versa.
How does CDM advisory connect to PSCS and PSDP advisory?
They are the cross-jurisdiction equivalents of the same duty-holder concept. CDM 2015 in the UK names the principal designer and principal contractor. The Irish Construction Regulations 2013 name the Project Supervisor Design Process (PSDP) and Project Supervisor Construction Stage (PSCS). A project running on both sides of the Irish Sea typically needs both. Our PSCS and PSDP advisory service runs the Irish-side appointment and statutory obligations, and our chartered advisors keep the duty-holder record consistent across both regimes.
