How to Save Money on Waste Removal and Tipping
In the first of our blog series on tips and tricks to save money on excavation, we look at how you can save money on waste removal and tipping.
As you may know, the cost of waste removal from construction sites is becoming more and more expensive. However, excavation waste often includes many different types of material, which can be disposed of in different ways. So before earthworks machines arrive on your site, it’s important to plan your project’s waste handling to minimise waste removal and tipping costs.
Types of Waste
There are many forms of excavation waste, from green waste to concrete waste, and these materials need to be disposed of in different ways, at varying costs.
Common types of waste include:
- Concrete slabs
- Concrete stumps
- All forms of concrete waste can be recycled so avoid mixing this with clean fill.
- Use a chainsaw to cut tree branches to a length that will fit down the side of the house with a bobcat or be placed straight into a truck. This waste can be taken directly to green recyclers.
- Top soil
- Always separate clean fill from all other waste where possible.
- Always place big rocks into separate loads
Demolition waste is a mixture of all of the above (concrete, green waste and clean fill) plus builders’ rubbish.
- Mixed waste is the most expensive to dump so minimise this category as much as possible and especially avoid including clean fill with mixed waste.
- The inclusion of fibro sheets in mixed waste leads to issues regarding suspicion of the fibro containing asbestos. A load may be refused at the tip if fibro is detected in the load so be careful to remove all fibro sheeting before dumping.
Procedure for Separating Waste for Removal and Tipping
As we already mentioned, it’s critical that your site manager/foreman or builder carefully plans your waste disposal before excavation work commences. You then need to ensure a procedure is followed to minimise waste removal and tipping costs. Everyone onsite must understand the goal of separating waste. For instance, even those responsible for blowing out a concrete pump must be conscious of separating waste. Traditionally they have covered all the clean fill and mixed waste with concrete, but this could ruin all your good planning.
The appropriate trades may need to attend to any disconnections that are required prior to arrival of machines
- Submit a Dial Before you Dig enquiry to identify any potential buried hazards
- Disconnect the hot water unit
- Disconnect gas
- Disconnect air-conditioning units
- Move the switch board
The builder needs to ensure all asbestos is removed from the worksite site prior to earthworks and construction commencing. Always use a reputable asbestos removal company that follows safe removal and disposal procedures.
Prepare Worksite for Machines
Prior to the arrival of earthworks machines, clean up the worksite and create as much room as possible for the machines to work and create separate waste piles. Excavation machines are charged on an hourly hire basis, so if work is delayed to create worksite space after the machines arrive, it may cost you unnecessary money.
Always Choose an Expert Earthworks Company
An expert excavation operator who has the skill to quickly and expertly identify and separate the different forms of waste for recycling and tipping will save you time, money and hassle on the worksite.
A good earthworks company will be aware of the most cost effective way to deal with waste, including:
- Identify and separate concrete waste for recycling
- Keep green waste separate
- Identify the most cost-effective clean fill tipping solution
- Dispose of mixed waste at the tip that accepts your mixed demolition material at the best price
