PSDP & PSCS Support That Designs the Risk Out Before You Build
We take on the statutory PSDP role, and coordinate the PSCS, under Ireland's Construction Regulations, and embed it directly in the engineering, so safety is built into how a live-site project is designed and executed, not layered on as paperwork afterwards.
- Statutory PSDP, integrating safety into the design from the earliest stages
- Structured HAZID and HAZOP risk identification before construction begins
- A project-specific Preliminary Safety and Health Plan, not a template
- Continuity into the PSCS, so design controls survive into construction
- Part of SHV Energy
- ISO 50001

What This Service Is
This service is EM3 taking on the formal statutory safety roles defined under Irish construction regulations, specifically Project Supervisor Design Process (PSDP), and supporting or coordinating with the Project Supervisor Construction Stage (PSCS). In practice this is not a standalone compliance service. It sits inside live industrial capital projects where engineering changes are being made, such as heat pump installations, plant upgrades or infrastructure modifications, and we embed these statutory responsibilities into the engineering design and delivery process, so safety is not a separate compliance layer but is built directly into how the project is designed and executed.
The PSDP role means we are responsible for integrating safety and health considerations into the design from the earliest stages through to construction readiness: coordinating designers, managing design risks, and making sure design decisions can be safely implemented in a live manufacturing environment. The PSCS interaction means we either take on or work alongside the construction-stage role to maintain continuity, so what was identified and controlled in design is actually carried through during site execution. It is typically used by large industrial and pharmaceutical sites in Ireland that must comply with the Safety, Health and Welfare at Work (Construction) Regulations.

The Challenge It Solves
Clients do not come looking for PSDP support. They come because they are about to execute a project inside a live facility and are exposed on multiple fronts at once. The actual problem is fragmentation: the design is being developed, contractors are being lined up and timelines are being set, but responsibility for safety is unclear, under-scoped or treated as a checkbox, and nobody has full ownership of how design decisions translate into risk on the ground.
In that situation, safety risks are being created in the design phase without being fully understood. Different designers make decisions in isolation, and no one coordinates how those decisions interact. The PSDP role exists in regulation precisely for this, but in reality it is often under-resourced or treated administratively rather than technically. The consequence is that by the time construction starts, safety issues surface as conflicts, redesigns, delays or restrictions on how the project can be executed. We are usually brought in when the project is already moving and the client needs to formalise control, so that risks are identified early, documented properly and designed out where possible rather than managed later on site.

How EM3 Delivers It
Formal appointment and registration
We make sure the PSDP appointment is properly defined, documented and aligned with the regulatory requirements, including the formal appointment, documentation control and the statutory registration forms linked to the role.
Coordinate the design environment
We engage with all of the designers involved and ensure the general principles of prevention are being applied across every design. Where they are not, we issue direction to designers and require design changes.
Structured risk identification
We run formal HAZID and HAZOP sessions, where the design risks are identified, documented and assessed before construction begins, rather than discovered on site.
Develop the Preliminary Safety and Health Plan
We build the plan specifically for your project, from the site conditions, design decisions and identified risks, with site visits, stakeholder coordination and review cycles before it is issued. This is not a template exercise.
Coordinate continuously
Throughout the design phase we coordinate the communication between designers, contractors and the client, escalating, documenting and communicating any decision that introduces or changes risk across all parties.
Carry it into construction
As the project moves toward construction we coordinate with the PSCS, so the safety considerations identified and controlled in design are not lost at the handover into site execution.
What You Receive
A Preliminary Safety and Health Plan
The most visible deliverable: a plan, built for your project, that defines how risks will be managed throughout the project lifecycle.
A fully coordinated design
A design environment where every input has been reviewed through a safety lens, risks have been identified, and mitigation is built into the design itself.
Documented stakeholder coordination
Records of the design decisions, risk escalations and the communication between designers and contractors across the project.
Statutory PSDP compliance
Proper appointment, documentation and registration under the Safety, Health and Welfare at Work (Construction) Regulations.
A de-risked project before construction
Issues that would normally appear during site execution identified earlier, which means fewer delays, fewer redesigns and fewer safety incidents once work starts.
PSDP-to-PSCS continuity
Safety intent carried from design into construction through coordination with the PSCS, rather than lost between phases.
Proven Outcome
On a heat-pump project at a live pharmaceutical site, EM3 took on the PSDP role while already delivering the detailed engineering design and project-development work. Safety and health were integrated directly into the detailed design, the system design, equipment sizing, operational logic and system integration, and EM3 developed the constructability planning and installation sequencing, identified the constraints around integrating new systems into existing operations, and set the commissioning and performance-validation strategies, all within the PSDP-aligned scope.
The result was not just compliance with the regulations. It was a project design that could be executed safely inside a live pharmaceutical environment without introducing uncontrolled risk, which is the entire point of doing PSDP technically rather than administratively.


Why EM3
Already embedded in the design
Many firms can fulfil the PSDP role. The difference is that we are already embedded in the engineering design itself, often already delivering detailed design, constructability and commissioning strategy before formally taking the role. Safety is shaped inside the design decisions from the start, not layered on after.
Technical, not administrative
The PSDP role is too often under-resourced or treated as paperwork. We treat it technically, with HAZID and HAZOP, design direction and risk genuinely designed out, which is where the regulation actually delivers value.
Independent of the chain
We operate independently of contractors and vendors, so we can challenge design and construction decisions where necessary, without commercial conflict.
Continuity across phases
We stay involved from design through construction support and coordinate with the PSCS, so the safety intent is not lost between design and execution.
How We Engage
Frequently Asked Questions
Is this just a compliance box-tick?
No. It is a statutory safety role, PSDP, treated technically rather than administratively. We run HAZID and HAZOP sessions, direct designers, and design hazards out rather than documenting them for someone else to manage on site.
Is this Ireland-specific?
Yes. PSDP and PSCS are statutory roles under Ireland's Safety, Health and Welfare at Work (Construction) Regulations, used on large industrial and pharmaceutical sites where design decisions directly affect operational risk.
What is the difference between PSDP and PSCS?
PSDP is the Project Supervisor for the Design Process, responsible for integrating safety into the design from the earliest stages. PSCS is the construction-stage role. We take on or coordinate with the PSCS so that what was controlled in design is actually carried through on site.
Why you rather than a standalone safety firm?
Because we are already embedded in the engineering design. Safety is shaped inside the design decisions from the start, not layered on afterwards, and we are independent of the contractors, so we can challenge decisions without commercial conflict.
What is the main deliverable?
The Preliminary Safety and Health Plan, built specifically for your project from the site conditions, design decisions and identified risks, plus a fully coordinated design environment and documented coordination across all stakeholders.
When should we bring you in?
As early in the design as possible. The whole value is identifying and designing out risk before construction, which means fewer conflicts, redesigns and delays once work starts on a live site.
