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 practices 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.

Demolition is one of the most hazardous parts of any construction project. It involves the destruction of buildings and other structures, and as such, it is important to ensure that the process is carried out safely and efficiently. Build2 has a team of experienced demolition experts who can carry out this process quickly and without incident.

The demolition process begins with the removal of all hazardous materials from the site. This includes asbestos, lead paint and other toxic substances. Once these have been safely removed, the actual demolition can commence. This usually involves using heavy machinery to tear down the structure bit by bit until it collapses. The rubble is then cleared away and disposed of properly.

The demolition stage of a construction project is important for a number of reasons. Firstly, it allows you to start with a clean slate and build the new structure exactly as you want it. Secondly, it can help to improve the overall aesthetic of the site and make it more attractive to potential buyers or tenants. Finally, demolishing an old, derelict building can also help to increase the value of the land. Build2 meticulously plans and executes our demolition services, tailoring the solution to ensure that each project is performed safely and efficiently.

Site Levelling

Site levelling is the process of making an uneven piece of land level. This is often necessary before any construction can take place, as it ensures that the foundation of the new structure will be stable and secure. There are a number of reasons why site levelling is important, some of which are described below.

One reason for levelling a construction site is to ensure that the foundation will be able to support the weight of the building. In New Zealand, where the landscape is so varied and uneven, this is especially important. Uneven land can cause structures to wobble and even collapse over time. By levelling the site before beginning construction, you can avoid this dangerous and costly scenario.

Site levelling is also necessary in order to ensure proper drainage. If your site isn’t properly levelled, water will pool in certain areas and cause damage to both the structure and the surrounding land. A properly graded and levelled site allows water to flow away from the building and prevents erosion caused by runoff.

Finally, improper grading can also lead to problems with settling later on down the road. When a building settles, it puts stress on both the foundation and the walls, which can lead to cracks and other structural damage. By levelling your site correctly, you can avoid these issues and ensure that your building will last for many years to come.

Build2 has the equipment and experience necessary to level even the most uneven of sites. We will work with you to ensure that your site is properly graded and levelled before construction begins, saving you time, money and hassle down the road.

Excavation is the process of digging trenches or holes in the ground for a variety of reasons. It is an important part of any construction project, as it allows you to prepare the site for foundation work and other construction activities.

One reason for excavation is to allow you to install the foundation of the new structure. The foundation is essential for supporting the weight of the building, and without it, the structure would be unstable and could collapse. By excavating the site and installing the foundation properly, you can ensure that your building will be safe and secure.

Excavation is also necessary to install utilities such as water lines, sewer lines and gas lines. These utilities need to be buried underground so that they are out of sight and out of mind. By excavating the site properly, you can ensure that these utilities will be installed correctly and without incident.

Finally, excavation is necessary to create a level surface for construction activities to take place. If your site isn’t levelled correctly, it will be difficult or impossible to build on it. Build2 has years of experience in excavation and knows how to properly grade and level a site so that construction can take place without any issues.

Concrete Cutting

Concrete cutting is a critical part of many construction projects. It is the process of cutting or shaping concrete using specialised tools and equipment. Concrete cutting is necessary for a number of reasons, including the following:

  • To create openings for windows and doors
  • To create joints between different sections of concrete
  • To remove damaged or defective concrete
  • To prepare a surface for paving or tiling

Concrete cutting can be performed by hand or with specialised equipment. Hand cutting is a slow and laborious process, but it can be used to cut small shapes and curves in concrete. Specialised equipment, such as saws and grinders, can be used to quickly and easily cut large pieces of concrete.

Many construction projects require extensive earthworks to prepare the site for construction. This is often a difficult and labour-intensive task, which is why it is important to have a team of experts performing this service. Build2 has years of experience in earthworks and knows how to get the job done quickly and efficiently.

There are a number of different types of earthworks that can be performed as part of a construction project. One common type of earthwork is excavation. This is the process of removing soil and rock from a site in order to prepare it for construction. Excavation can be used to create level foundations for buildings, or to create trenches for utilities and other infrastructure.

Another common type of earthwork is levelling. This is the process of making a site level by removing or adding soil and rocks. Levelling is often necessary before any construction can take place, as an uneven site will not be able to support a building or other structure properly
