Before any excavation begins, it is important that contractors consider how much waste material will actually need to be removed from the site. Getting this estimate right can make the difference between a smooth-running project and one that quickly runs into logistical and financial issues. Accurate volume calculations are essential for efficient planning, budgeting, and ensuring you have the right support in place for muck away services. Working with a professional muck away company like NWTH can help ensure you get this right.
When you start to estimate muck away volumes, the type of material you’re dealing with makes all the difference. Clay, topsoil, hardcore, and mixed waste all vary in density and how they behave once excavated. For example, compacted soil will expand when dug out, which is known as the “bulking factor”. A cubic metre of in-situ clay might increase by up to 40% once it’s out of the ground, meaning you’ll have much more to transport than it appears at first glance. This is where working with an experienced team like NWTH can be invaluable, as we understand how to account for these variations and can advise on realistic figures.
To get a reliable estimate, it’s worth carrying out a site survey before excavation begins. This allows you to assess the depth and spread of the dig, calculate total cubic metres, and apply the correct bulking factor. Even with careful planning, unexpected materials or weather conditions can affect your totals, so it’s sensible to include a small contingency in your calculations. By anticipating these variables, your muck away schedule can stay flexible without causing costly delays.
