Project Supervisor Design Process

PSDP Services in Ireland

At Arghco, we deliver more than exceptional design and build solutions — we deliver safety, compliance, and confidence. Our certified Project Supervisor Design Process (PSDP) professionals ensure that every project aligns with the Safety, Health and Welfare at Work (Construction) Regulations 2013, protecting clients, contractors, and end users from unnecessary risk.

Whether you are a homeowner planning a renovation, a developer managing multiple stakeholders, or a contractor delivering complex projects, Arghco provides PSDP services that keep your project compliant, efficient, and safe from start to finish.

What is the PSDP?

The Project Supervisor Design Process (PSDP) is a statutory role required on most construction projects in Ireland where more than one contractor is involved. The PSDP must be appointed by the Client before the design stage begins and remains in place until project handover.

The PSDP’s primary duty is to manage and coordinate health and safety in the design process, ensuring that risks are identified, mitigated, and communicated effectively.

• A PSDP is legally required where:
• The project lasts longer than 30 working days.
• The project requires more than 500 person-days of work.
• More than one contractor is engaged.

Failure to appoint a PSDP can result in enforcement action, penalties, and project delays.

Case Example

On a recent hospitality project in Dublin, Arghco’s PSDP team identified design-related fire safety risks at concept stage. By coordinating with architects and contractors, we introduced modifications that reduced risk without increasing cost. The result was a safer, fully compliant building delivered on schedule — and without last-minute redesigns.
