12 Ways Builders Cut Traffic Control Costs Without Cutting Safety

The best way to reduce traffic control costs is to stop paying for hours nobody uses: group short tasks around minimum charges, give an accurate scope, get the plan prepared early, have the site ready before the crew arrives and control variations. None of these touches the controls the traffic guidance scheme requires, so safety stays where it is.

Builders often try to save on traffic control by pushing the rate down or asking for one controller instead of two. Neither works well. The rate is a small lever, and crew size is set by the plan and the road. The real money is in minimums, waiting time, late changes and surprises on the day.

Where traffic control money actually goes

Before the twelve ways, it helps to know what drives an invoice. On a typical builder's job the cost is made up of:

• Controller hours, including set-up, pack-down and any overrun.
• Minimum charges, often 4 hours per controller and longer for vehicles and operators.
• Vehicles and specialist plant, such as truck-mounted attenuators (TMAs), VMS boards and arrow boards when the plan calls for them.
• Plans and permits, including revisions.
• Travel, especially for outer-suburban and regional sites.
• Waiting and cancellation, when the crew is committed but the work is not ready.

The last item is the one most builders underestimate. For background, see the traffic control cost guide.

A worked example: three deliveries, one booking

Example scenario: a builder on a three-storey residential site needs traffic control for three short tasks over a fortnight: a steel delivery on a Tuesday, a scaffold drop on the Thursday and a site-shed removal the following Monday. Each task needs about 2 hours of traffic control on the street, with two controllers.

Option 1: book each task separately

Each booking hits the 4-hour minimum per controller.

Example calculation, using a hypothetical rate of $80 per controller per hour:

1. 3 bookings × 2 controllers × 4 hours = 24 controller hours.
2. 24 × $80 = $1,920, before any vehicle charges or travel on each of the three days.

Option 2: group the tasks into one morning

The builder talks to the steel supplier, the scaffolder and the shed hire company and gets all three trucks booked for one morning, arriving at 7:00, 8:30 and 10:00. The crew sets up once and works about 6 hours including set-up and pack-down.

1. 1 booking × 2 controllers × 6 hours = 12 controller hours.
2. 12 × $80 = $960, with one set of vehicle and travel charges instead of three.

The safety arrangements are identical. The builder simply stopped paying for six hours of unused minimum and two extra mobilisations. What has to be checked: the traffic guidance scheme (TGS) must cover all three vehicle types and their positions, and the permit must cover the time. If the scaffold truck needs a different set-up from the steel truck, tell the person preparing the plan before the day.

The 12 ways, in order of how much they usually save

1. Group short tasks into one booking

As the example shows, minimum charges reward grouping. Keep a running list of tasks that need the street: deliveries, skip swaps, concrete, crane lifts, service connections. Book them together where the plan and permit allow. Our article on traffic control minimum hours explains why minimums exist.

2. Write an accurate scope

Describe the road, the plant, the access points and the restrictions you already know about. A side street or busy driveway the provider did not know about can mean an extra controller on the day, or a team leader who cannot set up safely and has to stop. Ten minutes on the scope saves hours on site.

3. Get the plan prepared early

A TGS prepared in a rush is more likely to miss something and need a revision. Giving the designer good information first time is covered in our guide to briefing a traffic management designer. The TGS must be prepared by a suitably qualified person; this article is not engineering advice.

4. Apply for permits with lead time

A permit that is not approved in time turns a booked crew into a cancellation fee. In NSW, work on some roads needs a road occupancy licence from Transport for NSW, and councils have their own permits. Check lead times with the road authority well before the crew is booked.

5. Have the site ready before the crew arrives

If the traffic crew arrives at 6:30 am and the excavator is not on site until 8:00 am, you will usually pay for that time. Have the work crew, plant and materials ready, and the area clear of parked cars if the plan relies on it.

6. Confirm deliveries the day before

Late concrete or a crane stuck in traffic keeps the controllers on the clock. A phone call the afternoon before, and a call when the truck leaves the yard, lets the team leader time the closure.

7. Book realistic hours

Under-booking does not save money. If the job will run 9 hours, booking 8 means an hour of overtime, sometimes in a higher time band. Ask the provider how long their set-up and pack-down take on your road.

8. Choose the right time band

Night and weekend rates are higher, but night work can sometimes allow a full closure that finishes the job in fewer shifts. Compare the total, not the rate. The day works vs night works guide walks through the trade-offs.

9. Use one provider for repeat work

A crew that knows your site needs less briefing, sets up faster and makes fewer mistakes. Many providers will also sharpen their price for regular work. Get quotes, but do not swap providers job by job for a few dollars an hour.

10. Nominate one person to approve variations

Extra controllers, overtime and added equipment should be approved by one named person on your side. Tell the provider who that is. This stops a well-meaning labourer agreeing to an extra four hours.

11. Sign dockets every day

Signed dockets with start and finish times, names and equipment let you check the invoice in minutes. Unsigned or missing dockets make disputes likely.

12. Review costs after each stage

After each stage, compare the invoice with the booking. Where did the hours go? Was there waiting time? Was a minimum wasted? Feed that into the next booking.

What a stage cost review looks like

Way 12 is the one most builders skip, so here is how it works in practice. Example scenario: after the first month of a project, the site manager lays the traffic control invoices next to the signed dockets and the original bookings and fills in a short review.

The review takes about half an hour and makes the waste obvious: two bookings paid mostly for unused minimum time, one paid for waiting, and one ran over because of a late plan change. None of those fixes involves fewer controllers or less protection. They are all about planning, timing and communication on the builder's side.

Share the review with the provider. A good provider will tell you what they saw on site, such as plant arriving late or the work area not being ready, and may suggest a better booking pattern for the next stage.

What you must not cut

Some savings are false economies that increase risk and can expose you to WHS liability. Work on or next to a road used by traffic is high-risk construction work. Do not:

• Run fewer controllers than the TGS requires.
• Leave out signs, TMAs or barriers the plan calls for.
• Ask the crew to skip the start-of-shift inspection or the briefing.
• Extend shifts past the provider's fatigue limits to avoid a second crew.
• Ask controllers to direct traffic without a valid plan.

If you think the plan is over-specified, ask the person who prepared it whether a different method is possible, and get any change in a revised plan. For WHS duties, check with SafeWork NSW or your state regulator.

A pre-booking checklist

Run through this before every booking:

• ☐ Have I grouped every task that needs the street this week?
• ☐ Does the scope include the road, plant, access points and restrictions?
• ☐ Is the TGS done and does it cover every task in the booking?
• ☐ Is the permit approved for the date and time?
• ☐ Are deliveries and plant confirmed for the start time?
• ☐ Have I booked realistic hours, including set-up and pack-down?
• ☐ Does the provider know who approves variations?
• ☐ Who signs the docket at the end of the day?

Next steps

Pick one upcoming week and list every task that needs the street, then see how many bookings you can combine. If you want a quick estimate before you call providers, the free traffic control cost estimator is a useful starting point.
