Site Preparation for Construction

Site Preparation

The term “breaking new ground” has been around for centuries. It refers to the first time a shovel cuts into the earth to begin a new construction project. This was the first step in preparing a section of land to be worked on. While construction practises have evolved over the years, it is still important that this “breaking ground” phase is carried out, taking the time to prepare a site for the construction project set to unfold.

Through years of experience, site preparation methods have been fine-tuned and optimised to set up construction projects for success. This important stage in the construction process plays a major role in determining the strength, quality and durability of the finished project. It takes an expert team to carry out all the necessary steps to ensure that careful and proper surface preparation takes place to provide an efficient and safe site for work to be carried out on.

It is important that site preparation is approached systematically to avoid any blind spots that may hinder a project’s success. Failing to adequately prepare a site can affect the structural integrity of the completed project. As it is the first stage of the project, failing to prepare the site correctly has a domino effect on all the steps proceeding it, causing time delays, financial losses and even putting the safety of the workers on the site at risk.

So what are the key steps for site prep to ensure that your project moves along smoothly, efficiently and without delays?

Site Evaluation

This stage involves assessing the general nature of the site and whether the proposed project is suitable for it. This step informs the planning process of what kind of earthworks need to be performed while assessing aspects such as size, accessibility, gradient etc. This will inform what will need to be planned for during the site preparation.

Soil Testing

An essential part of site prep is performing a geotechnical investigation. This determines the compositional properties and characteristics of the soil, rock and groundwater of the property. This allows you to evaluate the condition of the site, enabling you to collect data to design and construct foundations that will stand the test of time.

Site Plan Design

At this point, we are able to plan the design of your construction site. This plan will include various elements such as drainage systems, structures and the placement of septic tanks. This site plan will show all the necessary access roads for temporary storage areas and construction vehicles. This is the plan that will be used to apply for the relevant permits for demolition and earthworks.

Site Surveying

It is now time to outline where all structures, fixtures and utilities are going to be placed on the site. This involves marking off the site with survey pegs that act as a guide to ensure that everything is constructed correctly relative to your planning. If the property is in a heavily developed area, it is at this point that an underground utility map will be created to avoid damaging any important cables or pipes that may run through the site.

Site Clearing and Grading

Now it is time to start working on the land. This stage of site preparation involves grading and clearing the land for construction. Depending on the project, this may also involve the demolition of buildings and tree removal. The nature of New Zealand’s uneven landscape means that most of the time you will require earthworks and filling to level out uneven areas of the building site.

Site Compaction

The final stage of site preparation is compacting the soil. This is required to ensure that it is able to support the weight of the structures that are going to be constructed on the site. Once this has been done, the site is ready for excavation and foundation work to commence.

How Long Does Site Preparation Take?

The length of time for site preparation varies from project to project. It depends on the overall size of the project, as well as the number of earthworks required in order to prepare, grade and fill the land. For most residential building projects it usually takes between one or two months, while larger-scale developments and multi-commercial projects may be longer.
