RAMS (Risk Assessment and Method Statement)

What Is RAMS?

RAMS (Risk Assessment and Method Statement) is a formal construction safety planning document that integrates two traditionally separate elements:

1. Risk Assessment: Systematic identification of hazards associated with construction activities, evaluation of risk (likelihood × severity), and specification of control measures to reduce risk to acceptable levels
2. Method Statement: Detailed description of how construction work will be executed safely-the sequence of operations, specific procedures, equipment, personnel, and safety controls

Rather than producing separate risk assessments and method statements, UK construction practice (and increasingly EU practice) combines these into a single RAMS document, eliminating redundancy and ensuring that risk controls are explicitly reflected in operational procedures.

Why RAMS Exists: Construction is inherently hazardous: work at height, excavation, machinery operation, temporary structural systems, and rapid workforce assembly create injury risks. The UK CDM Regulations 2015 (implementing EU Construction Directive 92/57/EEC) require structured planning to prevent injuries before construction begins. RAMS translates regulatory requirements into operational reality: before a shovel moves dirt or a worker climbs scaffolding, construction teams must identify what could go wrong and specify how they will prevent it.

Scope & Content: A comprehensive RAMS covers:

• Site-wide hazards: Access/egress, site security, welfare facilities, emergency procedures, site traffic management, site inductions
• Activity-specific hazards: Excavation and groundworks, foundation work, structural steelwork, concrete placement, roof work (slates/tiles/metal sheets), façade work, mechanical/electrical installation, demolition
• Temporary systems: Scaffolding (competency requirements, inspection schedules), temporary supports, shoring, formwork
• Specialist work: Hot work (welding, cutting), confined space entry, powered access (MEWPs), tower cranes, asbestos removal, hazardous substance handling
• Coordination issues: When multiple trades work simultaneously or in sequence, identify interface hazards (e.g., concrete placement above workers below, electrical work above mechanical work)

Regulatory Standard / Framework:

• UK CDM Regulations 2015 (Construction Design and Management): Requires contractors managing construction projects with more than one contractor or duration exceeding 30 days to produce a RAMS before work begins
• EU Directive 92/57/EEC (Temporary or Mobile Construction Sites): Requires construction planning and coordination to prevent injuries-transposed into national law in EU member states
• UK Building Safety Act 2022 / Building Regulations 2016: Enhanced safety requirements for high-rise residential buildings, requiring comprehensive safety planning including RAMS
• HSE Approved Code of Practice L154: Provides guidance on CDM compliance and RAMS development

Applicable Industries: All construction projects involving: structural work, excavation, work at height, machinery operation, or projects lasting >30 days with multiple contractors. Even small projects (residential home renovations) may require basic RAMS if they involve specialist work (asbestos removal, structural opening creation).

How RAMS Works

RAMS development follows a structured process integrated with project planning:

Phase 1: Pre-Construction Planning

1. Design Review: The planning supervisor (or equivalent in EU jurisdictions) reviews the design and identifies inherent hazards that cannot be eliminated through design changes (e.g., a building's foundation requires deep excavation-inherent hazard). The designer must specify residual hazards in the Health & Safety File provided to the principal contractor.
2. Preliminary RAMS Outline: The principal contractor drafts a preliminary RAMS identifying major site-wide activities (site setup, structural frame, façade, MEP installation) and known high-risk activities (work at height, excavation, hot work). This preliminary RAMS enables early identification of whether the proposed construction sequence is feasible and safe.
3. Stakeholder Review: The preliminary RAMS is reviewed by: the planning supervisor, the client, insurers, and key subcontractors. Feedback is incorporated before finalization.

Phase 2: Detailed RAMS Development

1. Hazard Identification: For each planned activity, systematically identify hazards:

• Structural work: Hazards from unshored excavations (wall collapse), unsupported structural members (unplanned collapse), formwork failure, concrete placement (impact from falling concrete, pressure from fluid concrete), erection of precast elements (dropped loads)
• Scaffolding: Collapse (inadequate design, poor erection, overloading), falls from height, struck-by-hazards (loads dropped from above)
• Access/Egress: Slips, trips, falls on temporary site access; congestion during emergency evacuation
• Excavation: Trench collapse (unshored excavation, water infiltration, vibration from adjacent traffic), groundwater management, struck-by-hazards (utilities-electricity, gas, water, telecommunications buried in ground)
• Site Traffic: Collision hazards between vehicles and pedestrians; visibility issues; ground conditions deteriorating access roads

2. Risk Evaluation: For each hazard, evaluate:

• Likelihood (Probability): How likely is the hazard to cause harm? (high: routine exposure; medium: occasional; low: rare)
• Severity: What is the worst-case outcome? (low: minor injury; medium: serious injury/lost time; high: permanent disability/fatality)
• Risk Score: Likelihood × Severity matrix
• High Risk (red): Requires immediate elimination or robust control; cannot proceed without controls
• Medium Risk (yellow): Requires specified control measures
• Low Risk (green): General/standard controls sufficient

Example Risk Evaluation:

• Hazard: "Excavation to 4 meters depth, unshored trenches in sandy soil adjacent to building."
• Likelihood: High (soil instability in sandy soils is common; adjacent vibration from traffic common)
• Severity: High (trench collapse can trap/crush workers; fatality is possible)
• Risk Score: High Risk (red)
• Control Required: "Trenches >1.2 m depth must be shored using aluminum sheet piling or equivalent; design by structural engineer; inspection by competent person weekly and after any ground disturbance; sumps/dewatering if water table approaches; exclusion zones to prevent traffic vibration near trench"

3. Control Specification: For each hazard, specify control measures in priority order:

• Elimination: Can the hazard be eliminated? (e.g., "Rather than excavating to 4 m, use a shallower foundation design"-if feasible, preferred)
• Engineering Controls: Reduce hazard at source (shoring, temporary support structures, barriers, guards)
• Administrative Controls: Procedures, sequencing, exclusion zones, supervision, competency requirements, inspections
• PPE: Only as last resort supplementing engineering and administrative controls

4. Method Statement Development: For each activity, develop a detailed procedural step-by-step method statement:

• Sequence of Operations: Example: "Foundation excavation: (1) Site welfare setup, induction, (2) Utility strike avoidance (scanning for buried services), (3) Pre-excavation survey/photography, (4) Mass excavation to 0.5 m above target depth using 20-tonne excavator, (5) Final excavation by hand digging with supervision, (6) Installation of aluminum sheet piling, (7) Inspection by structural engineer, (8) Dewatering installation if needed, (9) Foundation trench ready for concrete placement"
• Competency Requirements: e.g., "Excavator operator: 5+ years experience, current CSCS (Construction Skills Certification Scheme) card, trained on site induction, supervised by site manager first day"
• Equipment Specification: e.g., "20-tonne CAT 320 excavator, certified/inspected annually, operated only by competent operator, exclusion zone 1.5× equipment height maintained"
• Inspection & Monitoring: e.g., "Shoring design certified by structural engineer; shoring inspected weekly and after any ground disturbance; records maintained on site; incompletely shored sections marked with red tape; daily toolbox talks on excavation hazards"

Phase 3: Implementation & Monitoring

1. Site Induction & Training: Before work begins, all personnel undergo induction covering site hazards, emergency procedures, and activity-specific method statements. RAMS is reviewed during induction so workers understand their assigned tasks and required controls.
2. Continuous Compliance: During construction:

• Supervisors verify that work is being executed per RAMS procedures
• Near-miss and incident investigations reference the RAMS: if an incident occurs, determine whether the RAMS control was inadequate or whether the worker failed to follow the RAMS
• Regular audits of RAMS compliance (unannounced inspections to verify controls are in place-e.g., is shoring installed per specification? Are exclusion zones maintained?)
• Weekly toolbox talks review high-risk activities and reinforce safe procedures

3. RAMS Revision: If project conditions change (soil conditions encountered differ from expected, weather impacts site access, schedule changes), the RAMS is revised to address new conditions. Revised RAMS is reviewed, approved, and communicated to affected personnel.

Why RAMS Matters: Operational impact

For HSSE Teams

RAMS is the primary safety planning document for construction. A well-developed RAMS with detailed control specifications, competency requirements, and inspection protocols drives safer construction and dramatically reduces incident rates. Conversely, a weak/generic RAMS (checklist templates with minimal customization to the specific project) fails to identify or control site-specific hazards, resulting in preventable injuries. HSSE teams use RAMS as the baseline for site supervision-auditing whether controls specified in the RAMS are actually implemented and maintained throughout construction.

For IT & CIOs

RAMS documentation has transitioned from paper/PDF to digital platforms. Digital RAMS systems enable: version control (multiple RAMS revisions during project lifecycle, with audit trail showing who approved each revision), accessibility (RAMS accessible on-site via tablets/mobile devices), integration with project schedules (RAMS activities linked to project timeline), and integration with incident reporting (incidents logged against specific RAMS activities). IT must ensure RAMS digital systems have appropriate security (only authorized personnel can modify RAMS), audit trails, and offline capability (RAMS must be accessible even if site loses internet connectivity).

Industry context

According to HSE (UK Health & Safety Executive) 2023 construction sector statistics, the fatal accident rate in construction is approximately 1 fatality per 100,000 workers annually-far higher than general industry average of 0.14 per 100,000. Approximately 60% of fatal construction accidents involve falls from height, 15% involve struck-by-hazards (dropped loads), and 10% involve excavation collapse. Organizations with comprehensive, regularly-updated RAMS and strong on-site compliance achieve fatal/serious injury rates 50% below industry average, demonstrating that systematic planning and control implementation is highly effective.

Implementing & Monitoring RAMS: From Manual to Digital

Traditional RAMS development was a lengthy process: the principal contractor hired a safety consultant, conducted site surveys, interviewed design team and key subcontractors, and produced a multi-hundred-page PDF document. After approval, this document was filed and distributed in printed form to supervisors-often resulting in poor compliance because field workers had difficulty accessing RAMS information or understanding application to their specific tasks.

Modern RAMS practice uses digital platforms and templates to accelerate development while ensuring quality:

Digital RAMS Systems: Platforms like SafeSite, iSafe, and Bridgit provide RAMS templates customized by project type and trade. Templates are completed by the principal contractor with project-specific details (site location, existing conditions, design drawings, project schedule). This accelerates RAMS development from weeks to days while ensuring comprehensive coverage of standard hazards.

Mobile Accessibility: Completed RAMS is accessible on-site via mobile devices (tablets, smartphones). Workers can search "excavation method statement" and immediately view detailed procedures, competency requirements, and control specifications. Photos and diagrams in digital RAMS improve clarity compared to text-heavy PDF documents.

Integration with Site Management: Digital RAMS systems integrate with project scheduling, site photos/BIM (Building Information Modeling), incident reporting, and toolbox talk tracking. Example: A toolbox talk on "Falls from Height-Scaffold Inspection" is automatically linked to the RAMS scaffold section, creating a chain from planning (RAMS) through implementation (worker training) to verification (incident tracking).

Compliance Audits: Digital systems generate automated checklists for RAMS compliance audits: "Excavation at Foundation Area 3: Is aluminum shoring installed per design? (Yes/No) If No, take photo and create non-conformance ticket." Digital audit records create objective evidence of site compliance.

Best Practices for RAMS

• Project-Specific Customization (Not Template Reuse): Resist the temptation to use a generic RAMS template from previous projects. Each project has unique site conditions, design, schedule, and workforce. A effective RAMS is customized: specific hazards identified through site surveys, specific controls specified based on site conditions (e.g., "adjacent building 2 m away requires particular care in excavation"), specific competency requirements tied to the actual tasks and site risks. A copied RAMS from another project is typically inadequate and creates liability if an incident occurs and the RAMS is found to have ignored project-specific hazards.
• Involvement of Subcontractors & Site Teams: Involve key subcontractors (structural frame, façade, MEP) in RAMS development. Each subcontractor understands their trade's hazards better than the principal contractor and can specify effective procedures. Additionally, involve site supervisors and experienced site staff-they know what works operationally and can identify when a RAMS procedure is impractical or likely to be bypassed. A RAMS that is unrealistic and bypassed by workers is worse than no RAMS.
• Regular Review & Revision During Construction: RAMS is not a one-time document; it evolves during construction as conditions change. Establish a monthly (or more frequent) RAMS review process: supervisor identifies conditions that differ from RAMS assumptions, near-miss/incident investigations reveal control inadequacies, or design changes require RAMS updates. Revised RAMS is approved, distributed, and communicated to affected personnel. This prevents RAMS from becoming obsolete midway through a project.
