If you’re currently planning a residential construction project, you’ve probably heard all about block cuts (or site cuts). But what exactly is a block cut, and what’s the big deal?
This blog will form a comprehensive guide for homeowners and builders alike, exploring what a block cut actually is, how much it costs, and why it’s such a crucial step of any construction project.
What Does a Block Cut Involve, and What Costs are Involved?
Basically, a block cut is the first step in the transformation of an empty or uneven block of land into a solid building foundation. It involves multiple steps, all of which combine to create a clear picture of the land, and its suitability for building on. Understanding these key stages will help you be better prepared to manage timelines, expectations, and associated project costs.
- Site Survey and Planning: The first stage is conducting a thorough survey of the site to establish what needs removing, the type of soil you’re working with (i.e. cleanfill or contaminated), and any other structures that need working around or removing.
- Clearing the Land: This involves the safe removal or vegetation, trees and other structures onsite. Excavators and specialised machinery will carefully remove anything and everything that could obstruct the leveling process and destabilise the foundation.
- Setting Cut Levels: These determine how much earth must be removed and are critical in creating a level foundation. This stage might even involve precision laser leveling to ensure complete accuracy.
- Excavation and Earthworks: Specialised machinery removes soil based on the cut levels, with the end goal of levelling the land to suit the building design e.g. a sloping property might call for terraces, where a flatter property might simply require levelling.
- Removing Excess Soil: Any excavation will generate a significant amount of soil that needs dealing with. Removal methods will vary depending on soil type and what level of contaminants might be present (if any).
- Compaction: Heavy rollers compress the soil to eliminate air pockets and increase density, ensuring a strong and stable foundation.
During the process, contractors will also consider drainage options, to prevent water from pooling near foundation and help prevent erosion.
The costs involved with block cutting will vary depending on how complex the job is, the site soil type, and the amount of excavation required. Site access is also a consideration, as sites that are more difficult to access might call for additional machinery or more manual labour, both of which will drive up costs.
Laying the Groundwork for Success
Whether you’re a homeowner looking to build the home of your dreams, or a contractor preparing for a large commercial project, one of the most important decisions you will make is choosing your excavation company. Skills and experience are essential here, to give your project the best possible foundation – literally and figuratively – to build from.
