Construction businesses waste thousands each year on payroll errors, ghost clock-ins, and manual award calculations. With workers spread across multiple sites, shift work kicking in at 4:30am, and penalty rates changing by the hour, tracking time accurately is nearly impossible without the right system.
The stakes are high. Construction recorded 37 worker fatalities in 2024, representing 20% of all workplace deaths. Beyond safety, Fair Work compliance requires precise tracking of penalty rates, RDOs, and overtime under awards such as the Building and Construction General On-Site Award.

What Is Time and Attendance?
Time and attendance is the process of tracking when employees start work, take breaks, and finish their workday. In construction, it’s about more than just hours — it’s about knowing who’s on which site, what project they’re working on, and whether they’re entitled to Saturday penalty rates or night shift loadings.
The system captures data like clock-in times, GPS location, job allocation, and break duration. This information is fed directly into payroll software, accounting systems, and project management tools. Get it wrong, and you’re looking at Fair Work penalties, worker disputes, and budget blowouts.
Time and Attendance Tracking Explained
Core functions include clock in/out, break tracking, and overtime recording. But construction needs go deeper. You need to know if that labourer clocked in at the Southbank site or the Preston project. Whether the carpenter worked a day shift (7am-3:30pm) or started at 4:30am and triggered shift penalties.
Modern systems integrate with HR, payroll, and accounting. When a worker clocks in, the system captures their exact location via GPS, logs the project code, and begins calculating their pay based on the applicable award or EBA for that specific site and time of day.
From Attendance Sheets to Digital Systems
Paper sign-in sheets dominated construction for decades. Workers scribbled their names, supervisors guessed arrival times, and admin staff spent hours deciphering handwriting and calculating hours in Excel.
Spreadsheet-based tracking was an improvement, but it still relied on manual entry and offered no way to verify that workers were actually on site. Buddy punching (where one worker clocks in for an absent mate) costs businesses thousands.
Cloud-based systems, combined with mobile apps, biometric verification, and GPS location settings have changed everything. Workers clock in from their phones, the system verifies their location, and hours flow automatically to payroll.
Why Construction Needs Specialised Time and Attendance Systems
Generic HR software assumes everyone works 9-5 in an office. Construction doesn’t work like that. You’ve got subbies, casuals, and permanents working across five job sites, starting at different times, operating under different EBAs, and moving between projects multiple times in a day.
Managing a Mobile Workforce
Your workers aren’t sitting at desks. They’re at a high-rise in the CBD one day, a residential development in the suburbs the next. There’s no central office, no fixed clock-in point, no way to physically verify attendance without driving to each site.
Workers might visit three different sites in one day. Traditional time clocks don’t cut it. You need mobile-first solutions that track location and let workers clock in from anywhere within your geofenced boundaries.
Tracking Work Hours Across Multiple Sites
When you’re running six projects simultaneously, every worker hour needs to be allocated to the right job for accurate costing. Project managers need to know if the Docklands build is running over on labour costs before it blows the budget.
The challenge isn’t just tracking hours — it’s tracking hours per project. Did the electrician spend four hours at Site A and four at Site B? Or was it six and two? Without accurate allocation, your job costing is guesswork, and your quotes for future projects are built on sand.
GPS verification solves this. The system knows which site the worker is at when they clock in, automatically allocates hours to the correct project, and flags anomalies when someone tries to charge eight hours to a site they were never at.
Shift Work and Rostering Challenges
Construction runs on early starts. Night shifts for urgent work. Weekend work to meet deadlines. Variable schedules that change week to week based on weather, material deliveries, and client demands.
Managing casual, part-time, and full-time workers across this chaos is brutal. A site supervisor might get a call at 6pm saying tomorrow’s concrete pour is delayed, requiring immediate roster changes and notifications to 15 workers.
CFMEU agreements add another layer. The 36-hour week arrangement means workers accrue RDOs differently than standard 38-hour weeks. Track it wrong, and you’re either underpaying workers or losing money to excessive paid time off.
Key Features of Time and Attendance Systems for Construction
Not all time and attendance systems in Australia are built for construction. Here’s what you actually need.
Geofencing for Site Verification
Geofencing creates a virtual boundary around your job site. Think of it as an invisible fence — workers can only clock in when they’re physically inside it. Set the radius anywhere from 50 metres to 1 kilometre, depending on site size. This method poses a risk to the Tracking of Workers and is not accepted by most Unions.
GPS Location Setting for Site Verification
Location Setting will provide the exact location when Clocking In & Out.
Employees arrive at the site, open the mobile app, select the Project, and then taps clock in. The system provides a pin location of the exact location. Privacy considerations matter under Australian law. The system should only locate the person at clock-in and clock-out, not continuously throughout the day. This is compliant with most Awards and Union regulations. Workers need to understand when and how their location is being recorded, and data must be stored securely.
Biometric Time Clocks and Clock In Apps
Fingerprint scanners work well in office environments but struggle on construction sites. Dust, dirt, and gloves interfere with readings. Outdoor heat and cold affect sensor accuracy.
Facial recognition is more practical. Workers remove their hardhat, look at their phone or a tablet mounted at site entry, and the system verifies their identity in under two seconds. It works with safety glasses on, captures photos for audit trails, and doesn’t require clean hands.
Mobile clock-in apps are the most flexible option. Workers use their own phones, clock in via GPS and facial verification, and the data syncs to your central system. No hardware to maintain at multiple sites, no exposed equipment getting damaged by weather.
Attendance Tracker and Real-Time Visibility
Site supervisors need a live dashboard showing exactly who’s on site right now. Not who was supposed to be there according to last week’s roster, but who actually clocked in this morning.
Real-time notifications solve communication gaps. The manager receives a notification when workers clock in late, when someone clocks in at the incorrect site, or when a key trade is missing from the morning muster. This matters when you’re coordinating crane deliveries, concrete pours, or inspections that can’t proceed without specific workers.
Additional Features That Matter
Custom reporting lets you slice data by project, trade, date range, or worker. Export to Excel, PDF, or directly into your accounting system. Generate weekly certified timesheets without manual data entry.
Site Induction and Safety Compliance
Construction is a high-risk industry with 37 fatalities recorded in 2024. Time and attendance systems play a critical role in meeting your WHS obligations.
Construction Safety and WHS Compliance
Under the WHS Act, PCBUs (Persons Conducting a Business or Undertaking) must maintain accurate records of who was on site and when. Digital attendance records satisfy these requirements automatically, creating timestamped, GPS-verified proof of site access.
Record-keeping matters during incidents. If there’s an accident, WorkSafe will want to know exactly who was on site, what time they arrived, and whether they’d completed required inductions. Paper sign-in sheets are notoriously unreliable — signatures are illegible, times are approximate, and sheets go missing.
Site Safety and Emergency Evacuation
Real-time attendance lists are lifesaving during emergencies. When an evacuation alarm sounds, supervisors need an instant list of everyone who should be on site.
Digital mustering speeds up emergency response. Workers assemble at the designated muster point while supervisors check off names against the live attendance list on their tablet. Missing someone? You know within 60 seconds, not after wandering the site yelling names.
Integration with visitor management systems extends this protection to subcontractors, suppliers, and clients visiting the site. The system tracks everyone who entered, regardless of employment status.
Credential and Qualification Tracking
White cards, trade licenses, working at heights tickets — construction workers carry multiple qualifications with different expiry dates. Tracking these manually across 50+ workers is a full-time job.
Automated credential management solves this. Upload qualifications to each worker’s profile, set expiry dates, and the system does the rest. It sends automated reminders 30 days and 7 days before expiry.
This connects directly to safety compliance requirements, advising prior to the expiry of the upcoming renewal requirement.
Managing Subcontractors and Labour Hire
Half your workforce might not be on your payroll. Subbies, agency workers, and specialist contractors add complexity to attendance tracking that generic systems can’t handle.
Tracking Subcontractor Hours
You’re managing five subcontractor companies on one site, each with distinct pay rates, agreements, and reporting requirements. When the concreter’s team clocks in alongside the plumber’s crew and your direct employees, the system needs to separate and track each group independently.
Verifying hours worked matters for invoicing. Subcontractors bill based on hours, so you need accurate records showing when their workers were on site, what they worked on, and for how long. Disputes disappear when both parties can see GPS-verified attendance data showing exact clock-in and clock-out times.
A centralised dashboard gives you visibility across all contractors. One screen shows every worker on site, regardless of who employs them, which project they’re allocated to, and what credentials they hold.
Preventing Time Theft and Buddy Punching
Buddy punching (clocking in for an absent worker) is more common than most admit. On paper timesheets it’s trivial: worker A signs worker B’s name, pockets full pay despite showing up two hours late.
The cost compounds. That’s not just two hours of false pay. It’s penalty rates calculated on non-existent overtime. It’s workers’ compensation insurance calculated on inflated hours. It’s job costing data that makes profitable projects look like they’re bleeding money.
Biometric verification stops this cold. Facial recognition, fingerprint scanning, or photo capture at clock-in requires the person punching in to be physically present. No mate can clock in on their behalf.
GPS adds another layer. Even if someone borrows your phone, they can’t clock in unless they’re actually standing at the job site. Combined with photo verification, time theft becomes virtually impossible.
Labour Hire Worker Tracking
Agency workers require the same attendance tracking as permanent staff, but with distinct reporting requirements. Labour hire agencies invoice based on the hours worked, requiring detailed timesheets that are broken down by site, project, and day.
Compliance with labour hire licensing laws adds complexity. You need to track which agency supplied each worker, maintain records of their employment status, and ensure all hours are properly accounted for in case of audit.
The system should handle this automatically, separating agency workers from direct employees in reporting, generating agency-specific timesheets, and maintaining the audit trail required under labour hire regulations.
Rostering and Employee Scheduling for Construction
Time tracking and scheduling need to work together. There’s no point tracking hours if you don’t know who should be where.
Workforce Scheduling Across Sites
Allocating workers to projects, balancing skill requirements across sites, and adjusting for last-minute changes requires flexibility that spreadsheets can’t deliver.
Modern rostering tools let you drag workers between sites, auto-fill rosters based on required skills, and instantly see if you’re overstaffed at one location while short-handed at another. Tag workers with their trades, qualifications, and availability, then let the system suggest optimal allocations.
Last-minute changes happen constantly. Weather delays, material shortages, client requests — construction schedules are fluid. Push notifications and SMS alerts keep workers informed when their roster changes, preventing no-shows and communication failures.
Rostered Days Off (RDOs) in Construction
RDOs are unique to construction under many CFMEU EBAs. Instead of working 38 ordinary hours across five days, workers typically work 36 hours and accrue RDOs — roughly one paid day off every 18-20 working days.
The 36-hour week means workers might work four nine-hour days, with the fifth day accruing toward RDOs. Or three twelve-hour shifts in remote locations. The system needs to track these accruals automatically, show workers their current RDO balance, and prevent double-booking when RDOs are taken.
Compliance with EBA requirements is non-negotiable. Get RDO calculations wrong and you’re underpaying entitlements, opening yourself to Fair Work claims and back-payment orders. Award interpretation software handles this automatically, applying the correct accrual rates based on hours worked.
Shift Patterns and Roster Templates
Day shifts, night shifts, split shifts, rotating rosters — construction uses them all. A system that can’t handle shift work simply doesn’t work for construction.
Shift templates save time. Define your standard patterns once, then apply them to rosters with a click. No rebuilding schedules from scratch every week.
Managing fatigue meets WHS requirements. The system should flag workers who are scheduled for excessive hours, have insufficient breaks between shifts, or exhibit patterns that violate fatigue management policies.
Penalty Rates and Overtime in Construction
This is where construction payroll gets complicated. Penalty rates can double or triple base pay depending on the time, day, and award applying.
Understanding Penalty Rates in Construction
Penalty rates compensate workers for working outside normal hours. Under the Building and Construction General On-Site Award, rates vary significantly.
- Saturday work typically attracts time-and-a-half for the first two hours, then double time after that.
- Sunday is double time all day.
- Public holidays hit 250% for full-time and part-time employees, 275% for casuals.
- Shift loadings apply when workers start outside ordinary hours (7am-6pm Monday to Friday).
Calculating this manually is error-prone and time-consuming. Which is why automated award interpretation matters.
Overtime Calculation Under Awards and EBAs
Award overtime kicks in after 38 ordinary hours per week under the Building and Construction Award. Or after 8 hours in a day, depending on the roster arrangement. First two hours at time-and-a-half, then double time after that.
CFMEU EBA overtime is often more generous — double time for all overtime under many agreements, no time-and-a-half tier at all. Some EBAs specify 36-hour weeks, meaning overtime starts earlier than award rates would suggest.
Daily versus weekly calculations create complexity. Under some arrangements, you calculate overtime both ways and pay whichever is higher.
Automated calculation eliminates errors. The system knows which award or EBA applies to each worker, tracks daily and weekly hours, applies the correct penalty rates based on time and day, and generates payroll data ready to import.
Award Interpretation and Payroll Integration
Pre-built awards save setup time. The Building and Construction Award is already configured, with penalty rates, overtime rules, allowances, and shift patterns built in. Select the award, assign it to your workers, and the system automatically applies the correct rates.
Custom EBA rule engines handle your enterprise agreements. Whether it’s a CFMEU, ETU, or CEPU agreement, the system can be configured to match your specific rates and conditions.
Seamless payroll export means timesheet data flows directly into your payroll system—hours worked, penalty rates applied, overtime calculated, allowances added. One click exports certified timesheets ready for payment processing.

How Wojo Simplifies Time and Attendance for Construction
Construction workforce management is uniquely complex — multiple sites, mobile workers, penalty rates that change by the hour, and compliance requirements that can trigger Fair Work investigations if you get them wrong. Wojo was built specifically to solve these challenges.
Mobile Timesheets with GPS
Workers clock in and out from their phones, no matter which site they’re at. GPS location tagging verifies the exact location, creating dispute-proof records of attendance.
73 Pre-Set Awards Plus Custom EBA Engine
The Building and Construction General On-Site Award is already configured with correct penalty rates, shift loadings, and overtime rules. Add your CFMEU, ETU, or CEPU agreements through the custom EBA engine, and the system automatically handles the calculations.
Real-Time Labour Costing
See labour costs per job in real-time, not weeks after payroll runs. Track hours against projects as workers clock in, compare actual costs to budget, and spot problems before they blow out. This visibility transforms project management from reactive damage control to proactive cost management.
Seamless Payroll Integration
Approved timesheets flow directly to Wojo Payroll or integrate with Xero, MYOB, QuickBooks, and other systems. STP Phase 2 compliant reporting happens automatically, and the whole process runs with minimal manual intervention.
Rostering and Scheduling
Allocate workers to sites, track RDO accruals for CFMEU agreements, and send push notifications when rosters change. The system shows you at a glance who’s scheduled where, flags potential issues like double-bookings or insufficient rest breaks, and keeps workers informed without endless phone calls.
Site Safety and Compliance
Track who’s on site in real-time for emergency evacuations and WHS reporting. Verify credentials and qualifications before allowing site access, with automated reminders for expiring tickets. Document management keeps compliance records organised and accessible for audits.
Unlimited Users and Scalable
Manage employees and subcontractors without per-user fees eating into your budget. Whether you’re running two sites with 20 workers or ten sites with 500, the system scales to match your business.
Making Time and Attendance Work for Your Business
Construction faces challenges that office-based businesses never see — workers spread across multiple sites, mobile teams that start before sunrise, complex award and EBA requirements that change based on the hour and day, and WHS obligations that demand accurate records.
The right time and attendance system handles GPS Location identification to verify workers are where they’re supposed to be, not claiming hours from home. It automates penalty rate calculations, so you’re not manually working out whether Saturday after 2pm is time-and-a-half or double time. Plus, it supports safety compliance, ensuring workers are kept safe, and WorkSafe inspectors are satisfied.
Digital systems save time, reduce errors, and improve profitability — but only if they’re built for construction’s unique needs. Generic HR software won’t cut it when you’re managing CFMEU RDOs, coordinating six concurrent projects, and tracking both employees and subcontractors.
