What is cut and fill?

29-07-2020

Cutting and filling is the process or moving earth from one place to another to make the ground more level. A ‘cut’ is made when the earth is removed from above the desired ground level and a ‘fill’ is when the earth is used to fill an empty part up to the required ground level. Cutting and filling is a common technique used to build an even ground surface. This process of moving earth holds a certain risk, particularly when the land being filled is going to be used for an infrastructure foundation. Whenever the land is moved the natural compaction is disturbed, and soil in this state is often described as ‘fluffed’ or ‘aerated’. For the earth to be safe enough for a construction projects to begin, it needs to be compacted to avoid settling.

The equipment required for cutting and filling

Special earthmoving equipment like skid-steer loaders or bulldozers are used for cutting and filling of the earth. Depending on the size and shape of your construction site, either a drum roll style compactor or a plate compactor may be used.

The average cost of cutting and filling

Some builders might say that putting a concrete slab on a cut and fill site is cheap, but it might cost you extra to solve the drainage problems that occur after the builder has left. Setting up drainage after completion of the infrastructure is very expensive. Excavation and earthmoving services cost around $90/hr. This can still vary depending on things like the size of the area to be excavated and the difficulty of access. In general, excavation and earthmoving might cost you somewhere around $80/hr to $100+/hr.

The disadvantages of cutting and filling

The cutting and filling of land does have certain disadvantages. For example, flattening land can increase the amount of sound that's carried across a property or affect natural windbreaks.

Alternatives to cutting and filling

Years back when houses were built on a slight slope, they were built on top of the land with small piers at one end of the block. This often gives an extra and useful area under the house to use for tools or storage. Normally these buildings have a wooden floor or a raised concrete floor. Some people brick around the fence of the house, fill it with sand and put a concrete floor on top of that. We recommend you discuss this process with your builder and then make a decision that best suits your infrastructure.

A Guide to Soil Disposal

29-07-2020

Whether you’re taking on a new construction site or need to remove dirt from your backyard, you may be wondering how to get rid of all that dirt in an efficient, cost-effective way. We’ve listed down a few common dirt disposal options to help you find the best way to dispose of dirt for your project.

1. Rent a tip bin

Renting a tip bin provides a simple option for disposing of soil. A tip bin can be delivered easily after an over the phone chat and then paid for depending on how long you want it. You can then work at your own pace with the bin left for you on your worksite. This option is most desirable if you want to handle the dirt yourself don’t want dirt sitting on top of your grass.

2. List it online!

You might find luck listing your soil online and it’s a good way to get rid of it for free. People are often looking for free materials to use and you won’t have to do any work. One man’s trash is another man’s treasure.

3. Leave a “Free” sign out

Similar to listing online, leaving our a “free” sign might catch the eye of potential takers in the area. This is one of the easiest ways to get rid of soil as contractors and DIY’s are always looking to cut costs.

4. Hire a removal company

You can also organise for a removal company to schedule a delivery window and send out someone who will determine the hauling price upon arrival. Then, they will load up your dirt and haul it away for you.

5. Take it to the dump

Finally, you can dump it at the landfill yourself. Most dumps will accept waste like soil for a set cost per tonne. You can search online for the cost for the dump in your local area.

What is site clearing?

29-07-2020

Site clearing is the process of removing all elements of a land area that obstructs the process of construction. It is the first step in any construction project. Site clearing affects every factor from planning to building permits as well as the safety of the project – but equally important is doing it in a way that minimises the impact on the land.

What is cleared from the site?

Vegetation

The vegetation you’ll need to clear from the site includes trees, bushes, and anything with a large root system – these will often get in the way of the foundations of your project and any cement work happening around them. For the bigger trees – cut them down to their stumps, remove the stumps, then remove the roots. Smaller trees and bushes can often be ripped out with an excavator all in one go. Try removing the smaller vegetation first, as that can clear up space to get the equipment in to fell the larger trees.

Rocks

Rocky terrain can hinder any construction project, especially when large rocks are present in the soil. Excavators with bucket and hammer attachments can help remove these.

Refuse and Debris

Refuse and debris not only includes rubbish and landfill but also abandoned buildings or infrastructure that need to be demolished or taken out of the ground.

When using a previous landfill, ensure the soil covering over the landfill has been flattened and contoured to prevent erosion and don’t expose the landfill underneath. Consider how deep you need your foundations over the landfill and whether the soil over it is deep and strong enough to support them. Remove all rubbish from the surface of the site.

Clearing previous infrastructure, buildings or foundations from the site may create some weak points where your foundations might fail. Ensure all weak points are filled with clay before you begin building.

How do I get a site clearing permit?

Area Permits

Area permits apply to owners of the land, people likely to become the landowners or have written authority to clear the land. With an area permit, you can clear any land area specified on the permit for an extended period of time (usually 2 years).

Purpose Permits

Purpose permits apply to land clearers who don’t own the land but have written permission to clear it.
