If you’re planning a new build on your commercial or residential property, you will more than likely have been told that you need a soil test to obtain your building permits. This involves making use of a reputable geotechnical engineering firm.
Typically, geotechnical engineers are responsible for the soil testing Melbourne law requires to be done before every new build. In addition to assessing soil and rock characteristics, a geotechnical engineer will design the safest and most functional foundation for your home. If you’re a property owner, you will have to commission a qualified geotechnical engineering firm on your behalf.
Know How to Choose the Best Geotechnical Team
If you’ve never used a geotechnical engineering firm before, you may be wondering how to distinguish one company from another. Fortunately, our team of experts have compiled a list of the top factors to keep in mind as you start shortlisting potential options.
1. Establish Your Project Needs
Finding a geotechnical team is as easy as doing a quick online search. However, it’s essential to point out that not all geotechnical teams are the same. With this in mind, your first step should be to define the construction needed. Will you be needing residential, commercial, or infrastructure?
Keep in mind that the foundation requirements for a residential building are significantly different to those of a commercial warehouse, so you will need a team that specialises in the build you need. You should also evaluate the scope and complexity of the project. This will determine the type of geotechnical investigation needed.
Some of the more common services you may require include the following:
- Site investigations: With this test, extensive testing is done to determine the following:
- Soil and rock characteristics
- Groundwater analysis to determine susceptibility to flooding
- Provides assessments of slope stability to determine landslide risks
- Assesses soil erosion potential
- Pavement rehabilitation services: These tests are conducted if your project involves the addition of pavements, walkways, or roads. Any existing pavements need to be assessed. Where possible, old and worn areas can be rehabilitated to reduce the overall cost of new materials. Where new pavements are to be added, the engineering firm should use recycled materials to save costs and enhance sustainability.
- Geotechnical reporting: Your geotechnical firm should also assess the area and provide a report of any potential challenges that may hamper your planned build. This can include issues such as clay-rich soil and soil contaminated with sulphur. Both of these factors can negatively affect your build’s foundations. In addition to identifying these reports, your geotechnical team will also recommend the necessary rehabilitative solutions. A common example of this is using sulphur-resistant cement where the soil contains high sulphur levels.
- Construction materials testing: An expert geotechnical team will also suggest that the right materials are used for the foundation and overall project. This often includes soil stability testing and concrete strength. Using the most effective construction materials will ensure a durable and safe build.
2. Consider the Area of Your Build
Another aspect to know is that Australia’s soil and ground conditions vary extensively. This means that you will have to ensure that your shortlisted engineering team have experience with doing tests in the geological conditions of your proposed sites. It’s worth pointing out that some areas may have additional geotechnical reporting requirements for your specific area. Local geotechnical teams will be up-to-date with all these regulatory requirements.
3. Evaluate the Firm’s Industry Standing
Once you have shortlisted geotechnical firms in your area, the next step is to assess the following aspects:
- Expertise and experience: Here, you want to look for a firm with a proven track record. They will need to display a strong understanding of local geological and soil conditions. Check the length of time in the industry and customer reviews from previous jobs.
- Accreditations and qualifications: Reputable firms will always be transparent about their qualifications and certifications. This will ensure that they are certified to perform the necessary services. A top accreditation to check for is the NATA accreditation. These are often highlighted on their official websites.
- Affordable pricing: It’s always a good idea to obtain detailed estimates and quotes from several different firms. Comparing costs and services will not only ensure that you get the best value for money, but will also eliminate being surprised by hidden costs down the line.
- Assess reporting and communication: You will also want to work with a firm that offers clear communication channels. Having a concise and transparent approach to your project ensures that they will take your project as seriously as you do. Be sure to check that they are available to start working on your project as soon as possible, as this will affect your construction planning.
Final Thoughts
Soil testing is a crucial aspect of any new build. It’s essential to team up with the best geotechnical engineering firm to ensure that your home or commercial building will have the strongest and most durable foundation.
