Before you start to create a new home, you need to make sure that it’s safe to build on the land. You also need to understand how land conditions affect the design and construction of the property. This is why you should have a geotechnical investigation carried out by a qualified geotechnical engineer. They will give you a report that should be used when finalising the design plans and throughout the construction.
What aspects of the land are investigated?
Various aspects of the land that you plan to build on are examined during a geotechnical investigation. These aspects include:
– Subsurface soil.
– Subsurface rock.
– Subsurface water.
Samples of the soil and water are sent off for laboratory testing. The geotechnical engineer also notes the characteristics of the soil that is present on the land.
The geotechnical report
Once the geotechnical engineer has noted these characteristics, and received the results of the laboratory tests, they compile a comprehensive geotechnical report.
The report includes:
– Full analysis of all results.
– Interpretation of the information contained in the results. This is important so that you are able to fully understand what the results mean for your building project.
– Recommendations for addressing any issues that have been identified.
Certain types of soil, such as those that have a high clay content, are more susceptible to movement. This happens because the soil is expansive. In the case of soils where clay is present, the clay absorbs moisture which causes it to expand. This type of expansion can cause problems with the foundation of a property, if the issue is not dealt with as part of the building process. Even building an external structure such as decking requires a soil test. read this great post regarding this https://www.juanmarco.net/deck-builders-guide-to-soil-types-and-testing/. It’s this type of issue that could be the subject of recommendations included in the geotechnical report.
How does the report affect the building of a property?
One of the most important things to remember is that you may need a geotechnical report in order to obtain a building permit. This is especially likely to be the case if there is an Erosion Management Overlay (EMO) in place for the area where you are planning to build. EMOs are applied in areas where there is an increased risk of landslides, and you need to make specific building plans to address the risks if this is the case. This is why a geotechnical report, with its recommendations, is so important.
Even if you do not need to have a geotechnical investigation completed, and a report produced, in order to build your property, it’s still a good idea to have the investigation carried out. Geotechnical engineers have the expertise to put to use to compile a useful report that can help ensure the safety and cost effectiveness of your building project.
The report is used by engineers, architects and construction professionals during the design and construction process. It helps them to use the right design and building methods and materials to avoid potential hazards and reduce risks. This means that the final structure should be secure and that you should not encounter too many nasty surprises along the way. This can save you a considerable amount of money, so the initial investment in the investigation is money well spent.
What are the risks of building without a geotechnical investigation?
If you do not have a geotechnical investigation carried out, you could encounter unexpected obstacles once you start to build. These obstacles could result in issues with design or construction causing timeframes to change and costs to rise. This is the last thing you want to happen. Delays could means that weather conditions change and cause further interruptions. You also need to think about the effects problems could have on your building budget especially if you have a tight one.
You also run the risk of your home not being securely built, if you choose not to go ahead with a geotechnical investigation. This may not be immediately apparent. Issues may start to occur months or years after construction is completed. This type of structural problem can be dangerous and is likely to be expensive to deal with. You never know when issues are going to arise and you may not be in a financial position to be able to deal with them.
Building projects are expensive to begin with, without the burden of unexpected additional costs. There will probably be some hurdles to encounter along the way, but you can avoid many major shocks by investing in a geotechnical investigation. Having the investigation report is a big help during the design stages of the project, and throughout the construction, as all of the professionals involved know what to expect. You end up saving money in the long term as you can plan ahead instead of having to deal with the unexpected.
