They are ready to get started.
Answer a few questions, so together we can come up with a plan that fits your timescales and budget.
We work through the complex process of organising the site works and carrying out the Geotechnical Investigation.
Written with an engineer in mind, so they know what action to take for design purposes.
Geotechnical investigations also known as ground investigations or geotechnical surveys, are mainly required to determine the nature of the ground conditions and enable a structural engineer to design the foundations of a building.
Developments of all sizes may require a Geotechnical Site Investigation to accurately aid in the design of foundations, roads, retaining walls and drainage.
A Geotechnical Investigation typically involves the testing of soil and groundwater to understand the engineering capacity of the soils.
The type of testing depends on the type of structures proposed and location of the site relative to the anticipated ground conditions and geology. This is normally understood in advance using a Desk Study.
Geotechnical investigations are typically required to determine the nature of the ground conditions and aid with the design of foundations, drainage systems and / or outline design. The scale of developments that may require a geotechnical investigation can range from domestic extensions to large scale commercial premises, on brownfield or greenfield land.
Lustre Consulting has gained valuable experience carrying out preliminary geotechnical investigations, typically combined with a Phase 2 Site Investigation to form a geo-environmental investigation. Such investigations are designed to assess both the environmental and geotechnical ground conditions within one combined investigation providing a more efficient and cost-effective approach. Our geo-environmental investigations enable the early identification of potential constraints posed by the condition of the ground, and if required, an indication of engineering solutions.
Each geotechnical investigation is site specific with the chosen exploratory method(s) depending on the site access, ground conditions and likely foundations (e.g. deep piles or traditional shallow pad foundations). Available methods include:
During the geotechnical investigation and depending on the ground conditions, a variety of techniques can be employed to assess the engineering capacity of the soils, including:
Lustre Consulting also has extensive experience in carrying out Soakage Testing to determine whether soakaways would be a suitable drainage option.
At Lustre Consulting, we specialise in designing cost-effective geotechnical investigations to assess the ground conditions and determine the engineering capacity of the site. Our investigations provide crucial data that supports safe and efficient foundation and structural design for your project, ensuring long-term stability.
To meet your requirements and ensure compliance with industry regulations, all our geotechnical investigations are conducted in strict accordance with British Standards (BS5930, BS1377, BS EN 1997-1) and BRE Guidance Notes, referencing the applicable Eurocodes where relevant. This ensures that our investigations meet the highest standards of accuracy and reliability, helping you avoid costly delays or compliance issues further down the line.
Our team of qualified and experienced geotechnical engineers are experts in recovering accurate samples, conducting in situ testing, and performing detailed soil logging in accordance with British Standards. We employ a range of advanced techniques including borehole drilling, trial pits, and dynamic probing, all tailored to the specific requirements of your site.
Following the geotechnical investigation, our findings are compiled into a comprehensive and interpretative report, offering clear and actionable conclusions. These reports include detailed recommendations for foundation design, drainage considerations, and any potential geotechnical challenges that may need to be addressed. By providing early insights into ground conditions, we help you make informed decisions that support safe and efficient construction, reducing the risk of unforeseen ground-related issues.
Our focus on transparency and technical accuracy ensures that you receive a geotechnical investigation report that meets the requirements of local planning authorities, civil engineers, and structural designers, giving you confidence in the success of your development project.
Do you have any NHBC requirements attached to your development? If so, the conditions may have details which require a Geotechnical Investigation to assess ground conditions for foundation design.
In terms of programming, we will usually require at least 1 to 2 weeks from receipt of formal instruction to mobilise onsite depending on the scale of the investigation. The geotechnical analysis on soils will take up to four weeks after submission of the last soil sample.
We will assess the testing requirements of your site as well as any access restrictions when we prepare our Geotechnical Investigation proposal. Our experienced engineers and consultants have worked on a range of sites where access restrictions have been overcome.
A geotechnical investigation should not commence until the location of all services has been determined as they pose a significant health and safety risk. If up-to-date plans are not available, we recommend requesting them from the utility companies. If timescales are tight, we recommend a service clearance survey which can be combined with a level survey or a topographical survey if required.
If you are unsure as to whether you require a Geotechnical Investigation, please give us a call, so together we can discuss your requirements. Alternatively, please send an email to info@lustreconsulting.com and provide us with the site location and description of the proposed development.
