Eliminate
Remove the hazard or redesign the work so exposure does not occur—for example, completing an activity at ground level where the project allows it.
NSW construction-site control guide
Construction Site Safety Controls NSW: A Practical WHS Planning Guide
A project-planning resource for clients, principal contractors, subcontractors, supervisors and workers coordinating construction activity in changing site conditions.
Direct answer
Effective construction site safety starts by understanding the work, people, plant, environment and interfaces before the task begins. Identify hazards, eliminate risks where reasonably practicable, then work down the hierarchy of controls. For high risk construction work, confirm that a site-specific safe work method statement is in place, understood and followed. Coordinate the controls daily, verify them in the field and review them whenever conditions or the work sequence change.
Purpose and boundaries
Use this guide to structure site-control conversations
Construction safety is not a single checklist and it is not created by personal protective equipment alone. Controls need to match the actual task, location, workers, plant, materials, access, adjacent activities and changing site conditions. Responsibilities also vary with the work and the parties involved.
This article gives a practical planning sequence. It is not legal advice, a safe work method statement, a risk assessment or a substitute for competent site-specific advice. Duty holders should confirm the current NSW legislation, approved codes of practice and regulator guidance that apply to their work.
Control framework
Work through the hierarchy of controls
SafeWork NSW describes the hierarchy as an order from the highest level of protection and reliability to the lowest. Elimination should be considered first. If elimination is not reasonably practicable, consider substitution, isolation and engineering controls, followed by administrative controls and personal protective equipment for remaining risk. A combination of controls may be required.
Substitute
Replace the hazard, material, plant or process with an option that creates less risk and is suitable for the task.
Isolate
Separate people from the hazard through physical separation, restricted access, barriers or controlled zones.
Engineering
Use physical design solutions such as guarding, edge protection, ventilation, mechanical aids or temporary works designed for the condition.
Administrative
Use procedures, permits, sequencing, signage, supervision, training and communication to support the higher-order controls.
PPE
Select, fit, use and maintain suitable PPE for residual risk. PPE supports the control system; it is not a replacement for higher-order options.
Control quality matters: record why the selected measures are suitable for the circumstances, confirm they are installed and used as intended, and review them when they are not effective or the work changes.
Existing SCE media
Site controls must work across people, plant and public interfaces
Before work begins
Translate project information into site-specific controls
Planning should connect the design, programme and procurement decisions with the way work will actually be performed. The earlier a hazard is addressed, the more options the project team usually has to eliminate exposure or use a higher-order control.
Define the work and interfaces
Confirm the task, location, sequence, people, plant, materials, access, services, adjacent trades, occupied areas, public boundaries and foreseeable changes.
Assign responsibility and communication
Record who makes decisions, who supervises the work, how workers and other duty holders are consulted, and how site rules and changes are communicated.
Check competency and resources
Verify the required licences, training, induction, plant information, permits, supervision, emergency arrangements and specialist input before mobilisation.
Plan verification
Set inspection points for access, temporary works, isolation, plant zones, environmental controls, housekeeping and any control that must remain effective throughout the task.
For NSW construction projects meeting the current regulatory definition and value threshold, SafeWork NSW identifies additional principal-contractor duties, including a written WHS management plan. Confirm the current requirements directly with the regulator for the specific project.
High risk construction work
Treat the SWMS as a live control document
SafeWork NSW states that a safe work method statement must be prepared for high risk construction work. It should identify the high risk work, associated hazards and risks, the control measures to be implemented and how those measures will be applied, monitored and reviewed.
A generic document that does not reflect the site, sequence, plant or work method will not guide the crew effectively. The relevant workers should understand the controls before work begins and know what requires the task to stop and be reviewed.
Practical SWMS review prompts
- Does it describe the actual task and current work area?
- Are the hazards, interfaces and control measures specific?
- Do controls follow the hierarchy rather than relying on PPE?
- Are responsibilities, hold points and stop-work triggers clear?
- Has the crew been consulted and briefed in a way they understand?
- Will it be reviewed if the method, environment or controls change?
During delivery
Use a repeatable daily site-control loop
Confirm
Check the planned work, crew, competency, plant, access, permits, weather and adjacent activities.
Brief
Discuss the task, controls, interfaces, emergency response and stop-work conditions with affected people.
Verify
Inspect the physical controls before exposure begins and at the defined hold points.
Coordinate
Manage changes, trade interaction, deliveries, exclusion zones, services, housekeeping and public boundaries.
Review
Stop and reassess after a change, incident, near miss, control failure or new hazard, then communicate the revised approach.
Common planning interfaces
Match the control plan to the site conditions
Each topic requires task-specific assessment and may require specialist advice, permits, design, testing or regulator guidance. These prompts help expose gaps before work starts.
Work at height and falling objects
Consider whether height exposure can be eliminated, then address access, edge protection, openings, dropped-object zones, rescue and changing surfaces.
Plant, vehicles and lifting
Separate people and plant where practicable; plan routes, exclusion zones, ground conditions, lifting interfaces, communication and authorised operation.
Electrical and existing services
Identify services, confirm isolation and verification arrangements, protect temporary supplies and coordinate penetration, excavation and demolition work.
Excavation and temporary works
Address service information, ground conditions, support, surcharge loads, access, water, inspections and design requirements for temporary conditions.
Dust, noise and substances
Evaluate elimination and substitution options, source controls, isolation, ventilation, monitoring, storage, spill response, hygiene and suitable residual PPE.
Occupants, neighbours and public areas
Plan separation, secure boundaries, delivery timing, signage, communication, noise and dust controls, emergency access and safe entry and exit routes.
Assurance
Keep evidence that controls were planned, applied and reviewed
Useful control evidence
- Current plans, permits, risk assessments and SWMS where required
- Induction, competency, licence and briefing records
- Plant, temporary works and control inspection records
- Photographs of critical physical controls and exclusion zones
- Consultation, coordination and change-control records
Review triggers
- The control does not work as intended
- The work method, sequence, plant or personnel changes
- A new hazard, incident or near miss occurs
- Consultation identifies a practical gap
- Site, weather, access or adjoining activity changes

Frequently asked questions
Construction site safety control FAQs
What is the first step in controlling a construction-site risk?
Understand the work and identify the hazard and who may be exposed. Then consider whether the hazard or exposure can be eliminated so far as reasonably practicable before moving to lower levels in the hierarchy of controls.
Is PPE enough to control construction risks?
No. PPE is generally the lowest level in the hierarchy and should address residual risk after elimination and other higher-order controls have been considered and applied where reasonably practicable. PPE must also be suitable, fitted, used and maintained correctly.
When is a SWMS required in NSW?
SafeWork NSW states that a safe work method statement must be prepared for high risk construction work. Duty holders should check the current WHS Regulation, Construction Work Code of Practice and regulator guidance for the specific activity.
When should construction controls be reviewed?
Review controls when they are not effective, before a relevant workplace change, when a new hazard is identified, after an incident or near miss, or when consultation indicates that a review is necessary. Communicate and record the revised approach.
What should a daily pre-start discussion cover?
Cover the planned work and sequence, crew and competency, site changes, plant and deliveries, access and exclusion zones, services, weather, adjacent activities, control verification, emergency arrangements and stop-work triggers.
How should multiple contractors coordinate safety controls?
Identify overlapping duties and interfaces, agree responsibilities and communication channels, share relevant risk information, coordinate sequencing and physical controls, and consult affected workers. Escalate conflicts before work proceeds.
Does this guide replace site-specific WHS documents?
No. This is a general planning guide. It does not replace a WHS management plan, SWMS, risk assessment, permit, design, emergency plan, competent supervision or any other project-specific document or duty that applies.
