Site Investigation

site investigation by esp


ESP has long established expertise in the successful design and implementation of site investigation works for a wide range of developments. This includes sites with elevated level of contaminants, difficult access and complex ground conditions. The site investigation techniques used are tailored to the site and development specific requirements.

Our expertise within site investigation includes:


What Is a Site Investigation?


Site investigations are our bread and butter here at ESP, they vary depending on the size and nature of the engineering work, development or end use. But usually the purpose is to determine the ground conditions and properties, including a geo-environmental assessment. They highlight unfavourable ground conditions or geo-hazards such as contamination or soft ground.

Site investigations allow us to obtain data to enable design of proposed structure enabling foundations to be designed for the specific site. Investigations should start with a thorough desk study, followed by intrusive works, which allows information to be collected, assessed and reported. ESP has long established expertise in the successful design and implementation of site investigation works for a wide range of developments for small and large clients.

Some of the broad ranging site investigation services we offer include: trial pitting, soakaway and permeability testing to BRE365.

We’re able to drill numerous types of boreholes such as: dynamic sampling, cable percussion drilling, rotary open hole or rotary coring. We can also undertake, dynamic probing, CBR or plate loading, ground gas monitoring, groundwater and surface water monitoring, ground surveying, geophysical, CPT testing, unexploded ordnance risk assessments.

More specialists investigation techniques include:

  • Drone surveys to obtain LiDAR topographic surveys
  • Hillslope movement monitoring
  • Groundwater pressure monitoring


Why Choose Earth Science Partnership For Your Site Investigation?


Our applied or engineering geologists supervise and control work on site in a safe and proactive manner enabling accurate data to be collected which is carried out in accordance with contemporary British and European standards. We use approved, safe sub contractors to keep our costs competitive and as a result the machinery and techniques we use are specific for each job. The site investigations techniques used are tailored to the site and proposed development such that the most practical and cost effective solution is adopted.



Our Site Investigation Services


We have dealt with schemes of all sizes from the largest Coal Mining Opencast Sites in Europe to individual house foundations, in many different environmental contexts – from mountain roads in Oman to the Cardiff Bay Barrage.

Comprehensive and accurate site investigation forms an integral part of our geotechnical and contamination assessments. With vast experience in site investigation and with a wide range of capabilities, ESP are experts in understanding ground processes and excel in providing effective solutions for any situation.

We use a number of accredited contractors supervised by ESP geoscientists for our intrusive site investigations. Methods include rotary drilling, cable percussion drilling, window sampling, trial pits and cone penetration testing. Sampling and logging of soil and rock is in accordance with contemporary British and European standards. We also have extensive experience in the use of geophysical methods in the investigation of both contamination plumes and in geotechnical applications including landslides.


Example Site Investigations Completed By ESP


For example previous site investigations works we have conducted please see some example projects below:


Project Example: Investigation into ground conditions for the proposed construction of a new hospital.

site investigation by esp - hospital plans imageESP was employed by an NHS trust to investigate, and establish the ground conditions beneath a former colliery tip. It was proposed that a new hospital was to be built on the site; however this was pending the results of a detailed geotechnical study.

Our assessment included advice on the geotechnical design as well as land contamination as the site was located up gradient of a river. Advice on drainage and contaminant migration was also provided.

Project Example: Geotechnical and Geoenvironmental Site Investigation for the Reading Station Redevelopment.

site investigation by esp - Reading Station Redevelopment artist impressionThis project involved an extensive site investigation including rotary and cable percussion boreholes, dynamic probing, trial pitting and geotechnical and geoenvironmental testing both on site and in lab conditions. It also included the construction of numerous groundwater and gas monitoring installations. Our involvement in the development allowed the client to achieve key construction and project deadlines and for works to continue on schedule.
