Construction Phase Plans

Construction Phase Plans

Construction Phase Plans (CPPs) are a core requirement of CDM 2015, setting out the health and safety arrangements for the construction phase of a project. In NexusRMS, phase planning is available as a separate addon at £49 per month.

Plan Numbering & Statuses

Plans follow the format CPP-2025-0042 and progress through a defined lifecycle:

1. Draft — plan is being prepared and can be freely edited
2. Submitted — submitted for approval review
3. Approved — formally approved by the relevant duty holder
4. Active — plan is in effect for the live construction phase
5. Archived — project completed, plan retained for records

Plan Sections

Each construction phase plan contains comprehensive JSON-structured sections covering all aspects of site health and safety:

• Key personnel — role, name, and contact details for all responsible persons
• Emergency procedures — evacuation routes, assembly points, first aid arrangements
• Welfare facilities — toilets, washing, rest areas, drinking water provisions
• Site rules — PPE requirements, access restrictions, prohibited activities
• Significant hazards — major hazards identified for the project
• Control measures — specific measures to mitigate identified hazards
• Health risks — occupational health considerations and monitoring
• Work packages — sequencing and phasing of construction activities
• Coordination arrangements — multi-contractor coordination protocols
• Consultation arrangements — worker consultation and engagement methods
• Training requirements — mandatory training and competence standards
• Monitoring arrangements — inspection schedules and compliance checks

Auto-Population from Project

When creating a new phase plan, the system can auto-populate key sections from the linked project record:

• Project overview and description
• Management structure and key contacts
• Default site rules from organisation templates
• Standard welfare facility requirements
• Emergency procedure templates
• Linked RAMS documents and their hazard assessments

Revision System

The createRevision method replicates the current plan, increments the revision number, and resets the approval status back to draft. This ensures a complete audit trail of all plan versions whilst allowing necessary updates during the construction phase.

Approval Workflow

Phase plans follow a strict approval sequence:

1. submitForApproval — moves plan from draft to submitted status
2. approve — formally approves the plan with approver details and timestamp
3. activate — puts the approved plan into active use on site
4. archive — retires the plan upon project completion

Hazard Management

Phase plan hazards are linked via a pivot table to the central hazard library. Each hazard entry includes an is_selected flag and an optional rams_document_id link, connecting hazards to their detailed risk assessments. Project-specific hazards not found in the library can be added as custom entries.

Site Inductions

The PhasePlanInduction model tracks crew induction records for each phase plan. Every worker accessing the site must complete an induction covering the plan contents, site rules, and emergency procedures before commencing work.

Additional Features

• Safe system of work library — reusable safe work methods that can be referenced across multiple plans
• Pre-construction information (PCI) — a separate data section capturing client-provided information about existing hazards and site conditions
• CDM link — direct relationship to the F10 notification via the f10Notification relationship, maintaining traceability to HSE notification
• Templates — reusable plan templates for common project types, reducing setup time for recurring work
• PDF generation — full phase plan document export for printing, distribution, and site display

Pre-Construction Information

The PCI section captures essential information that the client must provide before construction begins. This includes existing site hazards, asbestos surveys, structural condition reports, utility locations, and any other factors that may affect health and safety during the construction phase.
