Geotechnical report

Geotechnical engineers

If you ask a construction worker, he/she will tell you that the foundation is the most important part of the building. If the foundation isn’t good the building will always be at risk of falling. Now the question that arises is how you know if you have the right foundation. Many people believe that having concrete in the foundation makes it stronger. That might be true but stronger does not always mean efficient. In order for you to have a sustainable foundation you need to analyse many different factors other than all the materials used in the foundation.

Firm Soil for a Firm Foundation

Having solid bricks and concrete in the foundation is good but have you ever thought about the soil surrounding those bricks. What if that soil has a softness nature? In such a scenario your concrete, brick, materials and investment will all go down the drain. One of the most common issues construction companies face is regarding the nature of soil. Sometimes the location is ideal for the proposed building, but the soil isn’t perfect for it. In old days people would just look for another place to build their proposed building but not in the 21st century. In the 21st century there are professional geotechnical engineers that can help you in firming up soft soil or soil improvement. Different materials and techniques can be used to make the soil firm. Once the soil has been made firm, you can then start working on the proposed structure.

As mentioned above, geotechnical engineering is one of the most vast and in-depth branches of Civil Engineering. It is really a matter of how these services are being used by the company and how they are making it work. Utilization of waste materials is a concept that really pushes in. Waste materials can be used to improve soil properties, if these properties are actually improved for soil stabilization it can make the whole process time and cost effective.

Soil Mechanics:

Soil Mechanics happens to be one of the most knowledgeable and important aspects of the Geotechnical Industry. Most of the Geotechnical consultants present in the industry are focused on researching and developing their expertise on the matter and having a proper grip of the subject can set you up on a path of getting ultimate competitive edge.

Sustainability of the Land

Sustainability of the land is also an important aspect to look at. Once you have made the soil firm you need to see if the foundation and the structure above it can stand different natural and manmade events. You must analyse if the land can sustain the proposed building for the next couple of decades.

Always Consider a Geotechnical Engineer in your project

Proper research and knowledge are required in order to know what type of infrastructure and buildings require what type of foundations. Remember that laying the foundations is the groundwork for any infrastructure and the rest of the steps follow afterwards and if the foundation isn’t strong then anything that stands above it isn’t going to be strong as well. This is just an indicator of how important geotechnical engineers’ rule is, when it comes to construction. It is very important for construction companies to always have an experienced geotechnical engineer on payroll who can be available when they need him/her to be. There are many professional geotechnical engineering consultants in Auckland, Hamilton and Rotorua. You can hire them to evaluate the land you are looking to purchase or construct a structure on.  As a result, if you are looking for a Geotech report or land assessment contact us and we can help you with the cost of your geotechnical engineering needs.

What is Geotech report or Soil Report?

 

All the above technical words are normal for
geotechnical engineers and they are quite familiar with it, but how about the people
without geotechnical knowledge. Let’s start and explain in a simple word what is
geotech or soil reports?

This is a useful topic for all developers, first
home buyers, landowners or anyone who is interested to know more about geotech
report.

First of all, we need to understand the following
basic soil types.

Very Coarse

  • Boulders:
     particle sizes are usually above 200mm
    and it comes in angular, subangular and round shapes.
  • Cobbles:
    particle sizes are between 60-200mm and it comes in angular, subangular and
    round shapes.

Coarse Soils

  • Coarse
    Gravels: sizes are between 20-60mm and it also comes in angular, subangular and
    round shapes.
  • Medium
    Gravels: particle sizes are between 6-20mm and the shapes are similar to coarse
    gravels.
  • Fine
    Gravels: particle sizes are between 2-6mm and it is easily visible to the naked
    eye. The particle shapes are quite similar to above gravels.

 Sands

  • Coarse
    sands: particle shapes are angular, subangular, flat, rounded and elongated
    with sizes between 0.6-2mm.
  • Medium
    sands: sizes are between 0.2-0.6 and it is visible to the naked eye. Shapes are
    same as coarse sands.
  • Fine
    Sands: particle shapes are same as coarse and medium sands with 0.06-0.2mm and
    it is visible to the naked eye.

Fine Soils

  • Silts:
    Particle sizes are between 0.002 – 0.06 mm and it comes in coarse, medium and
    fine. The grain sizes are not visible to the naked eye.
  • Clays:
    It is not easy for people without geotechnical knowledge to recognise the difference
    between silt and clay. Clay materials have intermediate to high plasticity and it
    will shrink on drying whether which usually leaves cracks.

Organic Soils

  • Organic
    clay, silt or sand: the sizes are varying and contains substantial amounts of
    organic vegetable matter.
  • Peats:
    particle sizes are varying and predominantly plant material which remains dark
    brown and black with a distinctive smell.

Each one of the above soil types have their own characteristics and strength which will be tested on site to find out. Geotechnical engineers or geologists will go on site to test the soil and write the soil description in your geotechnical or soil report.

In addition, geotechnical engineers will inspect your
site to make sure there is no geotechnical hazards on your site. After inspection
and soil testing the field data will be analysed to make sure the soil
underneath of your proposed building has enough strength. Furthermore, the
geotechnical or geotech engineer will give you the values for undrained or
bearing capacity of the soil. As a result, the geotechnical report will give you
recommendations on what type of foundations are suitable for your projects.

Geotechnical report also will help the structural
engineers to design an appropriate foundation for your proposed buildings or
structures.

Overall geotechnical or soil report helps you to find out the information underneath the ground to design the suitable foundation. So lets contact geotest group and find out the cost of geotech report for your project.
