Geotechnical Investigations Explained
In the UK there is a lot of planning that goes into any new building project. It's not all about building and bricklaying. Before the ball starts rolling there's planning, preparation, investigation and groundwork that goes on, this is the case for any site. Before any project gets the go ahead an initial desktop investigation must have been carried out, preliminary assessments must also be carried out to avoid future problems.
The conditions and ground of any given site vary, it’s not uncommon for the composition of the land to vary across short distances, typically indicating there could be an issue with the environment, one common cause being drainage that could impact the development and how it reacts massively. The site's history must also be taken into consideration as this could impact how the land reacts to change and added pressure.
What To Consider Before A Geotechnical Investigation
COMPOSITION ON THE GROUND
Some land is made up of soft soil or it may have been filled previously as new developments settle over time issues may occur. Carrying out a detailed inspection (investigation) allows any potential issues to be identified, without a proper investigation you may experience ground movement and create structural problems with anything built on the land.
HISTORY
Great knowledge can be achieved by studying the site’s history and allow you to understand how future developments will behave. We know that in developed areas where there have been coal mines there is a high risk that ground may collapse, we also know that hazardous gasses, contaminated water and fire risks are imminent. Geotechnical investigations allow for thorough assessments and help provide a positive outcome.
GROUND MOVEMENT
There are many things that can cause ground movement such as tunnelling, swelling and clay shrinkage. Geotechnical investigations can provide knowledge into any movement which may occur. Protocols can be put into place to prevent unnecessary damage as buildings and structures close by will have also been assessed.
Choosing A Geotechnical Investigation Company
You may think that shopping around and looking for the cheapest company is a great place to start but this isn’t always the case. You’re also going to want to get the best value for the money you’re going to be spending. You want your chosen company to provide the most accurate analysis possible, not doing this could cause you money in the long run.
What could happen if you don’t choose the right geological company?
- Wasted time and money
- Slow turnaround
- Difficult and inadequate reports
- Poor samples and site results
- Failure to meet the sites needs
- Failed or incomplete samples
- Poorly conducted site surveys
So you may be asking yourself how you choose the right company. We always suggest making yourself a checklist, think about your expectations before you decide what company you're going to work with.
Below are a few examples of questions to ask yourself.
- Do they have reviews and feedback that you can access easily?
- Who have they worked for previously and evidence of the work they have carried out.
- Is the reputation commendable?
- Are they able to find issues and also offer solutions?
- Can they work at your speed and keep up with deadlines?
- Will their reports and paperwork be personalised to suit your project and requirements?
- Will the company take their time to review and understand your project clearly?
