Are you planning a build on a newly acquired property? If your build is the first of its kind on the land, then you may already know that you need specific building permits before any breaking of ground is allowed. To obtain these, you will be required to hire a geotechnical engineering team to perform a series of assessments.
These assessments form part of the required soil test Melbourne laws require for new residential and commercial builds. Once the assessments are performed, the results are compiled in a geotechnical report. This post takes a closer look at this report and highlights its importance and what you can expect to find in it.
Understanding Why Soil Tests are Important in Australia
Soil testing is a crucial first step in every residential or commercial build in Australia. Essentially, these tests and assessments are performed to test and assess soil characteristics.
Several factors determine how well the soil will hold the intended structure. The most common of these include the following:
- Soil reactivity to moisture changes
- Bearing capacity determines whether the soil can support the structure’s weight
- Chemical properties that identify the presence of contaminants or corrosive elements
- Identifies groundwater levels to determine soil stability during water movement
The primary goal of soil testing is to establish how safe and durable a structure will be when built on specific ground types. Additionally, information gathered in this process will also help geotechnical engineers determine what materials and building techniques should be used to create the strongest foundation.
Information gathered in these tests and assessments is generally compiled in a geotechnical report, which forms the basis of any permits being issued. This report is vital to establishing how best to proceed safely and legally with any intended build. Our team of geotechnical experts has compiled a few essential factors that will highlight why this report is essential.
Understand the Why Behind a Geotechnical Report
A comprehensive geotechnical report is an essential tool that compiles all the information needed to mitigate risks and understand various ground conditions of the intended build area. Here are a few crucial reasons to insist on a comprehensive Geotech report:
- Assists with risk mitigation: Soil testing identifies potential soil hazards such as flooding, landslides, and instability. Results are listed on the geotechnical report.
- Helps with foundation and structure design: Data supplied in the report provides engineers with information needed to choose the best foundation design and building technique.
- Allows for cost savings: Having access to a detailed report reduces the likelihood of costly repairs in the future.
- Ensures Compliance: Ensures that your build and building techniques are compliant with local regulations.
Know What a Geotechnical Report Tells You
A geotechnical report can be quite overwhelming if you’re dealing with one for the first time. The good news is that most engineering companies create a layout that makes it super easy for all involved parties to read and understand.
The average geotechnical report is made up of the following essential components:
- Site analysis: In this section, you’ll find all the information regarding the existing vegetation, topography, and drainage patterns. This information helps your engineer identify potential challenges and any suspected drainage issues.
- Soil testing results: This section forms the core of your geotechnical report and details the soil’s strength, composition, and reaction to moisture levels. Information here will help to determine building techniques and materials to opt for.
- Foundation recommendations: Comprehensive soil tests will also highlight recommendations for specific or specialised foundation designs to ensure the safest footing. This will go a long way toward keeping your build safe and structurally sound.
- Groundwater and drainage analysis: Information about groundwater levels as well as the drainage capacity is detailed here. This data is used to determine how susceptible your building is to issues such as flooding and erosion.
- Risk assessment: In this section, the report identifies potential risks such as soil movement or landslides. Your engineer will use this information to create the relevant mitigation strategies.
Know How Much These Reports Cost
When you’re planning your development budget, you’ll need to factor in the costs associated with obtaining the right report. It’s crucial to keep in mind that the cost of these reports can vary from site to site. For the most part, reports can vary between $1,000 and $3,000.
A few of the key factors that can determine the cost of your geotechnical report include the following:
- Site location (difficult-to-access sites can cost more to assess)
- Scope and testing requirements (Type of build will determine types of tests needed)
- Complexity of the site (Areas with increased risk factors may increase cost factors)
Final Thoughts
When planning a new build, your first course of action should always be to find a reputable geotechnical engineering company. Not only will they ensure that tests are performed correctly and safely, but the results will help your team design the safest and most durable foundation. In addition to this, having access to the relevant report will also make the permit obtaining process much easier!
