Civil Works & Road Construction SWMS
Road construction, kerb and channel, drainage, and traffic management on civil infrastructure projects.
SWMS variants reference your state's WHS legislation. Instant download after payment.
This SWMS covers civil works and road construction — pavement construction and reconstruction, kerb and channel installation, drainage (pits, pipes, subsoil), asphalt and spray seal, line marking, and the associated traffic management on public roads. It is written for civil contractors performing road construction and reconstruction, subcontractors engaged in specific civil packages (kerbing, drainage, paving), traffic controllers operating under TfNSW or state roads authority accreditation, and Principal Contractors coordinating civil operations on infrastructure projects.
Civil works on roads is among the highest-exposure work categories in Australian construction, with workers operating in close proximity to moving traffic as the dominant mechanism of fatality. It engages multiple HRCW categories under Schedule 1 of the WHS Regulation 2025 (NSW): Category 2 (work on or adjacent to a road or railway used by traffic) applies throughout — distinct from Category 1 which covers construction on a road under a principal contractor arrangement; Category 13 (powered mobile plant) applies to every plant operation; Category 14 (trenches deeper than 1.5 metres) applies to drainage and service trenches; and Category 17 (diving work) may apply where river or harbour civil works are involved. Traffic Control Plans (TCPs) under AS 1742.3 (Manual of Uniform Traffic Control Devices — Traffic control for works on roads) are the foundational control. Under r. 298 a SWMS must be prepared before HRCW commences. This document is CIH-authored against the current regulatory baseline.
Hazards identified
13 hazards covered, sorted by priority.
Fatal or serious injury to workers on foot; road-works struck-by incidents consistently rank as the leading workplace fatality mechanism in civil construction.
Fatal crush or run-over injury from reversing and slewing plant operating within a space shared with workers on foot; concrete trucks, graders, and rollers have large blind spots.
Burial and fatal asphyxiation; drainage trenches on road projects routinely exceed 1.5 metres and are often in unstable backfill or reactive clays.
Electrocution (HV cable strike), gas explosion, or water inundation; urban road corridors are densely serviced and BYDA plans have frequent inaccuracies in legacy infrastructure.
Silicosis and lung cancer at cumulative exposures above the 0.05 mg/m3 WES; pavement cutting on concrete roads and saw-cutting of kerb generates substantial silica.
Third-degree burns from asphalt at 140-160 degrees Celsius during hot-mix placement; splash and contact injuries to legs and feet during screed operations.
Permanent hearing loss for workers exposed above 85 dB(A) LAeq,8h; peak levels on saw operations regularly exceed 110 dB(C).
Chronic lower-back injury and MSD from sustained vibration exposure above ISO 2631 action value; a career-duration risk for roller and milling operators.
Increased struck-by risk from reduced public driver visibility; fatigue-induced errors during extended night shifts; higher severity in night-time traffic incidents.
Respiratory irritation and skin burns from bitumen fume inhalation and hot contact; PAH (polycyclic aromatic hydrocarbons) in bitumen are suspected carcinogens at high cumulative exposure.
Operator crush injury from roller or grader rollover on pavement-shoulder edges, batters, or unexpected ground movement; unrestrained operators attempting to jump clear are crushed by the roll bar.
Lower-back and shoulder MSD from lifting pit lids (50-120 kg concrete), drainage pipe sections, and traffic control signage across a full shift.
Core temperature elevation from combined radiant heat of hot asphalt and sun exposure; cognitive impairment increases struck-by and tool-injury risk.
Control measures
Hierarchy-of-controls order: elimination → substitution → isolation → engineering → administrative → PPE.
- 1Traffic Control Plan (TCP) prepared to AS 1742.3 (Manual of Uniform Traffic Control Devices — Traffic control for works on roads) by an accredited TCP designer (TfNSW Prepare a Work Zone Traffic Management Plan, RIIWHS301 or equivalent); TCP approved by the road authority before work commences.
- 2Traffic controllers hold current Implement Traffic Control Plans (ITCP) and Control Traffic with Stop-Slow Bat (equivalents RIICCM201 and RIICCM202) qualifications under the accredited training framework; certified and in-date for the duration of the project.
- 3Worksite delineation: Type 1 Temporary Traffic Barriers (concrete or water-filled) for works exposed to traffic speeds above 60 km/h; lower-speed works use cones and signage per the TCP; buffer zones and taper lengths per AS 1742.3 formulae; advance warning signs at distances per the speed limit.
- 4BYDA (Before You Dig Australia) lookup for every excavation; services hand-located by vacuum excavation within 2 metres of any located service; additional pre-excavation investigation for legacy infrastructure on older roads where BYDA coverage is incomplete.
- 5Trench support per r. 78 of the WHS Regulation 2025 and the Code of Practice: Excavation Work: battering, benching, or shoring for all excavations deeper than 1.5 m; competent-person design for deeper or non-standard trenches.
- 6Silica dust control: wet-cut methods for all pavement saw-cutting and kerb cutting; water suppression on milling machines; HEPA-captured extraction where wet methods not practicable; P2/P3 respirators for workers in dust-generating zones; air monitoring during extended saw-cutting operations per the Code of Practice: Managing the Risks of Respirable Crystalline Silica.
- 7Plant and pedestrian separation: internal worksite traffic plan separating workers on foot from plant movement; spotter on reversing plant; two-way radio between spotter and operator; physical barriers between traffic lanes and worker zones.
- 8Hot asphalt safety: leather boots rated for radiant heat; long trousers and long sleeves (fire-resistant where splash risk is high); face shield for screed and hand-rake operators within splash range of hot mix; burn first-aid and eyewash immediately available at the paving train.
- 9Hearing conservation: Class 4/5 hearing protection mandatory in designated zones; cab noise on roller and milling plant monitored and attenuated where internal level exceeds 80 dB(A); high-visibility ear defenders preferred for worksite compatibility.
- 10Vibration management: anti-vibration seats on rollers and milling plant maintained; rotation of roller and milling operators to limit continuous exposure; worker reporting of symptoms triggers exposure review.
- 11Night-work controls: additional lighting to AS 1158 (Lighting for roads and public spaces) at work areas; high-intensity retroreflective clothing to AS/NZS 4602.1 (Class D/N) for all workers; fatigue management per the Code of Practice: Managing the Risks of Working at Night (where adopted); shift-length caps; meal and rest breaks scheduled through the night.
- 12Bitumen and emulsion controls: SDS for each product; P2 respirator for workers within fume range during spray operations; skin protection for hot bitumen contact; decontamination facilities at the job's end of shift.
- 13Plant rollover prevention: ROPS and FOPS certification current; seatbelt use mandatory per r. 215; rollers not operated across steep batters without competent-person assessment; stockpile edges maintained at safe offset from the roller operating zone.
- 14Manual handling controls: mechanical aids for pit lid lifts (magnetic lifters, hoists), drainage pipe handling (pipe hooks, crane slings), and sign placement (trolley for large signage); two-person lift for any load over 25 kg.
- 15Heat management per the Code of Practice: Managing the Risks of Working in Heat: water stations at work sites, shaded rest breaks, rest-work cycles adjusted for ambient temperature and WBGT, pavement operations scheduled early morning or night during heatwave periods, and cooling vests for plant operators in hot cabs.
- 16PPE baseline in the work zone: hard hat to AS/NZS 1801, high-visibility vest/jacket to AS/NZS 4602.1 (Class D/N day/night — mandatory for road work), safety footwear to AS/NZS 2210.3, hearing protection in designated zones, P2 respirator for dust-generating operations, and safety eyewear.
- 17Daily pre-start: toolbox talk covering TCP changes, identified hazards, plant movements, and coordination across crews; attendance recorded and distributed to Principal Contractor and road authority as required.

High-Risk Construction Work triggered
All road construction and reconstruction work occurs on or adjacent to a road used by public traffic; Category 2 engages continuously across the project.
Rollers, graders, milling machines, pavers, trucks, and excavators are in routine use throughout civil works, engaging Category 13.
Drainage pit and pipe installations, service relocations, and pavement underdrain construction frequently exceed 1.5 m depth.
Where the civil work is organised under a principal contractor arrangement for construction work on or adjacent to a road, Category 1 engages distinct from Category 2.
Civil road-works incidents are among the most heavily investigated workplace incidents in Australia. Failure to have an approved TCP, to implement the SWMS controls, or to protect workers from traffic is prosecutable under r. 300 of the WHS Regulation 2025 and — where reckless conduct is involved — under s. 31 of the WHS Act as a Category 1 offence with penalties up to $3.993 million for a body corporate and 5 years' imprisonment for an individual officer. Road authorities (TfNSW, state roads agencies) have separate contractual and accreditation penalties including work stoppage, accreditation suspension, and contract termination. SafeWork NSW has prosecuted numerous road-works struck-by incidents resulting in significant penalties.

Worked example
A civil contractor is engaged on a 2.4 km section of Parramatta Road reconstruction in Sydney, NSW. Scope: full-depth pavement rebuild, kerb and channel replacement, new drainage, and asphalt surfacing. Work is night-shift only (10 pm to 5 am) to minimise traffic impact, over 14 weeks. Crew: 18 across plant operators, labourers, and two traffic controllers per shift. Before mobilisation this SWMS is issued alongside the TCP approved by TfNSW. Night-shift fatigue management implemented: 7-hour shifts, no more than 5 consecutive night shifts, transport home provided. Silica controls applied to saw-cutting: wet-cut method and P3 respirators for the two workers on the saw crew, air monitoring scheduled for week 2. Two-day delay from a near-miss — a spoil truck driver reported fatigue symptoms mid-shift; the fatigue-management plan was reviewed and shift start-times adjusted.

Frequently asked questions
Who can design a Traffic Control Plan?
In NSW, a TCP must be designed by a person who has completed the TfNSW Prepare a Work Zone Traffic Management Plan qualification (nationally recognised RIIWHS302 or equivalent). The designer is accredited by TfNSW and listed on the NSW Roads and Maritime accredited persons database. Other states have equivalent accreditation frameworks — Victoria (VicRoads Worksite TM), Queensland (TMR accredited), and so on. An unaccredited TCP will not be approved by the road authority.
What's the difference between HRCW Category 1 and Category 2?
Category 2 applies where work is carried out on or adjacent to a road or railway corridor used by traffic, regardless of whether there's a formal principal contractor arrangement. Category 1 applies specifically where construction work is carried out on or adjacent to a road or railway corridor used by traffic AND there is a principal contractor engaged. In practice most road works engage Category 2, and larger projects with a PC arrangement also engage Category 1. Both are listed in Schedule 1 and both trigger SWMS obligations.
Do traffic controllers need to be on the SWMS?
Yes. Traffic controllers are workers on the site and the SWMS must cover their activity. Their specific controls (positioning within a safe buffer zone, fall-arrest on elevated platforms, night-visibility garments, fatigue management during long shifts) are different from the civil crew's but must be documented. Many projects integrate a traffic management SWMS alongside the civil SWMS — this document covers the core civil scope with traffic controller controls integrated.
Can work continue in heavy rain or during a storm?
Risk-assessed decision. Light rain typically does not stop civil works but may introduce slip hazards and reduce plant stability on earthworks. Heavy rain or storms introduce worker visibility issues for traffic, excavation stability concerns, and electrocution risk from water ingress near electrical plant. The SWMS includes a decision framework for weather-driven work suspension; local site supervisor makes the call based on current conditions and forecasts. Heavy storm activity on a night shift is a common trigger for shift cancellation.
What are the key differences between this SWMS and the Earthmoving SWMS?
Earthmoving is the bulk earthworks scope — cut, fill, haul — typically in earthworks areas. Civil works and roads is the road corridor scope — pavement, drainage, kerbing, asphalt, traffic — operating within an active traffic environment. The traffic-management controls are the defining difference. Some projects engage both SWMS in sequence: earthmoving for bulk grading, followed by civil works for pavement and drainage. For combined scope, both documents should be issued rather than attempting to merge.
Does this cover bitumen sealing operations specifically?
At the framework level, yes. Bitumen sealing is mentioned in the bitumen chemical controls and hot asphalt controls. For dedicated high-volume sealing operations with specialised spray plant, additional controls around emulsion temperature, spray nozzle proximity, and PAH exposure are typically required — adapt the SWMS with the sealing-specific method statement for the spray crew. The core civil SWMS controls remain applicable.
