A vac truck can arrive with the right equipment and crew, but the job can still lose time if the site is not ready.

Limited access, unclear underground service information, nowhere suitable to position the truck, other trades working through the excavation area or unexpected spoil can all affect how smoothly the job runs.

If you have already decided that vacuum excavation is suitable for the work, preparing the site before the truck arrives can help the crew get started with fewer delays.

Before the Vac Truck Arrives

Before the booking date, check that you have covered the basics:

confirm the exact work area
provide available underground service information
make sure the truck can access the site
identify a suitable truck position
estimate the hose distance to the work area
explain what material is expected
confirm where spoil will be taken or handled
coordinate the work with other trades
check whether traffic control is required
make sure the site contact is available when the crew arrives

If you are still at the booking stage, our vac truck booking guide for the Gold Coast covers the information worth providing before confirming the job.

Confirm Exactly Where the Work Will Take Place

One of the simplest ways to avoid confusion is to identify the work area before the vac truck arrives.

The crew should know where excavation or material removal needs to take place, what the work is intended to achieve and whether there are several separate areas around the site.

On a larger project, that may mean marking pothole locations, trench lines, pits or specific sections of the work area.

Clear instructions at the start of the job reduce the chance of the truck being positioned in the wrong area or having to move repeatedly between locations.

Have Underground Service Information Ready

Vacuum excavation is commonly used where underground pipes, cables and other infrastructure need to be exposed, but that does not remove the need for proper site information.

Any available service plans, site markings and relevant project information should be ready before excavation begins.

The excavation crew needs to understand what is known about the area and where existing services may be located.

If you are unfamiliar with the process itself, our article on how vacuum trucks are used on the Gold Coast explains how vac trucks can assist with potholing and exposing underground infrastructure.

Check That the Truck Can Reach the Site

Vac trucks are large vehicles, so access should be considered before the booking rather than when the truck is already at the gate.

Things worth checking include:

gate width
turning space
overhead clearance
soft or unstable ground
parked vehicles
temporary fencing
stored materials
other plant operating nearby

A truck may not need to sit directly beside the excavation, but difficult access can affect where it can be positioned and how much hose is required.

Choose a Suitable Position for the Vac Truck

Truck positioning affects more than convenience.

The chosen location needs to allow the operator to work while accounting for the excavation area, hose route, surrounding plant, workers and site traffic.

Before the crew arrives, consider whether the intended position:

blocks another access point
interferes with deliveries
conflicts with crane or plant movements
sits in a live traffic area
creates unnecessary hose distance
needs to remain clear for emergency access

On tight sites, it is worth discussing truck position with the provider beforehand rather than assuming there will be enough room on the day.

Estimate the Hose Distance

The distance between the truck and the work area can affect how the job is set up.

A short hose run across an open site is very different from reaching behind a building, through a restricted corridor or into an area where the truck cannot enter.

Let the provider know if the work is separated from the nearest practical truck position by:

buildings
fences
retaining walls
landscaping
pedestrian areas
active construction zones
roadways

Even an approximate distance is more useful than finding out after the truck arrives that the work area is much farther away than expected.

Explain What Material Needs to Be Removed

The crew should know what they are likely to encounter.

Depending on the project, a vac truck may be dealing with soil, wet spoil, mud, slurry, water or other suitable material.

The material type can influence how the work is completed and how the collected material needs to be handled afterwards.

If there is any possibility of unusual or contaminated material, raise it before the job begins rather than once material is already being collected.

Think About Spoil Volume and Disposal

Vac trucks collect material in an onboard tank, so the amount being removed matters.

Potholing around several services may produce a relatively small volume of spoil. A longer trench, pit clean-out or larger excavation may generate considerably more.

An approximate idea of the excavation size helps the provider plan around tank capacity and disposal.

For larger jobs, also clarify:

where collected material is expected to go
whether disposal is part of the scope
whether multiple loads may be required
whether different materials need to remain separate

Coordinate Other Trades Before Work Starts

Vacuum excavation often takes place on sites where several contractors are working at once.

If another crew is operating through the same area, the vac truck may not be able to start immediately even if it arrives on time.

Before the booking, make sure relevant trades know:

where the excavation will happen
when the vac truck is expected
which access routes need to stay clear
whether plant or materials need to be moved
who is responsible for coordinating the work area

A few minutes of coordination beforehand can prevent the crew from waiting while the site is reorganised.

Check Whether the Vac Truck Will Affect Traffic

Not every vac truck job needs traffic control, but it should be considered where the truck or work area affects a road, shoulder, driveway, lane, pedestrian route or other live traffic environment.

Waiting until the truck arrives to discover that traffic arrangements are needed can delay the entire job.

If the work is near live traffic, discuss the location and proposed truck position before the booking date.

For projects where traffic management is required, Get Directed also provides traffic control services on the Gold Coast.

Make Sure the Work Area Is Accessible

The excavation point itself also needs to be accessible.

Where practical, remove unnecessary obstacles from around the work area before the truck arrives.

That might include:

stored materials
temporary barriers that are no longer required
parked vehicles
unused equipment
loose debris

This does not mean clearing controls that are required for safety. It simply means avoiding preventable obstructions that stop the crew from reaching the planned work area.

Confirm the Scope With the Site Contact

The person meeting the crew should understand what has been booked.

They should be able to confirm:

where the work starts
the required excavation or clean-up
available service information
where the truck can position
site access rules
who to speak to if the scope changes

If the site contact is not the person who arranged the booking, make sure the job information has been passed on before the crew arrives.

Plan Around Site Inductions and Access Requirements

Some construction and infrastructure sites have induction, sign-in or access requirements that need to be completed before work can start.

If the crew needs specific instructions before entering the site, let the provider know in advance.

That may include:

site sign-in procedures
designated entry points
escort requirements
restricted operating hours
parking instructions
mandatory site PPE

The goal is to avoid using booked operating time on administrative issues that could have been organised earlier.

What If the Site Conditions Change?

Construction sites rarely stay exactly the same from one week to the next.

If access, excavation locations, ground conditions or the scope of work changes after the booking has been made, tell the provider before the truck arrives.

A change that seems minor from the site can affect truck positioning, equipment requirements or the amount of material expected.

Updating the crew beforehand gives them a chance to plan for the revised conditions.

Preparing for Different Types of Vac Truck Work

The preparation required can vary according to the job.

Potholing

Mark the intended pothole locations and have available underground service information ready. Make sure the truck and hose can reach each location without unnecessary repositioning.

Trenching

Confirm the trench alignment, expected depth and surrounding infrastructure. If the work extends across a larger section of the site, consider how the truck will move or reposition as work progresses.

Slurry and Wet Spoil Removal

Estimate the amount of material where possible and provide information about what produced it. Clarify how the collected material will be handled after removal.

Pit and Drain Cleaning

Make sure the relevant pits or drains are accessible and identify any restrictions around truck positioning, hose access or nearby traffic.

Site Preparation FAQs

How Much Space Does a Vac Truck Need?

The amount of space required depends on the truck, the site and where the work is located. Provide access dimensions and photos beforehand if space is limited.

Does the Vac Truck Need to Park Next to the Excavation?

Not necessarily. Vacuum hoses allow the truck to work from a distance, but longer hose runs should be discussed before the job so the provider can plan the setup.

Should Underground Services Be Marked Before the Truck Arrives?

Available service information and relevant site markings should be prepared before excavation begins. The exact requirements depend on the project and work area.

What Should I Do If the Site Has Limited Access?

Tell the provider before booking and provide measurements, photos or other useful access information. This helps determine whether the proposed truck position and hose run are practical.

Do I Need Traffic Control for Vac Truck Work?

It depends on where the truck and work area are located. If the job affects live traffic, pedestrian movement or road access, traffic control requirements should be considered before work begins.

What Happens If the Scope Changes Before the Booking?

Contact the provider with the updated details. Changes to access, excavation size, material volume or work location can affect how the job needs to be planned.
