A Project Quality Plan (PQP), Project Safety and Health Plan (PSHP), Project Environmental Management Plan (PEMP), or an integrated Project QHSE Plan is typically developed, owned, and controlled by the Main Contractor, who bears the overall contractual responsibility for delivering the project in compliance with the client's requirements, applicable legislation, and relevant management system standards.
However, although the Main Contractor is responsible for the overall plan, its preparation is rarely undertaken in isolation. Specialist subcontractors, suppliers, and trade contractors are normally required to contribute discipline-specific information within their respective scopes of work.
For example, even where the Main Contractor employs its own Mechanical & Electrical (M&E) Manager or M&E Engineers, the appointed M&E specialist subcontractor is expected to provide technical input relating to:
- Method statements and work sequences,
- Inspection and Test Plans (ITPs),
- QA/QC procedures,
- Risk assessments and safe work practices,
- Environmental control measures,
- Testing, commissioning, and handover procedures,
- Competency requirements and resource planning and
- Discipline-specific statutory or client requirements.
These inputs are then reviewed, coordinated, and incorporated into the overall Project QHSE Plan by the Main Contractor to ensure consistency, eliminate conflicts between trades, and maintain a single, integrated management system for the project.
This collaborative approach recognises that while the Main Contractor retains overall accountability, specialist subcontractors possess the technical expertise necessary to define the most appropriate controls and procedures for their respective disciplines.
Consequently, the Project QHSE Plan becomes a coordinated document representing the combined expertise of the entire project delivery team rather than merely the work of the Main Contractor alone.
