The complex nature of geotechnical and geoenvironmental designs and the frequent requirement for third-party certification require skilled engineers to support client teams during construction. 

Our Construction Inspection Services 

CGL’s activities during the construction process can be divided into two main areas: 

  • Monitoring and supervision of remediation measures on contaminated land
  • Inspection of earthworks and building formations

Alongside these procedures, CGL regularly provides inspection and monitoring services to temporary works schemes.

Activities on contaminated sites range from simple construction inspection, testing, and certification of capping layers in domestic gardens to supervision of large-scale hydrocarbon remediation projects.

In some cases, it is necessary to use innovative methods which requires detailed knowledge of soil chemistry and engineering properties to arrive at successful conclusions. 

In previous projects, our expert team at CGL has used e-clay stabilisation and in-ground barriers to avoid issues with regard to migration of groundwater contamination that would entail several years of monitoring to satisfy the regulator.

On a more routine level, our experienced construction inspection engineers direct and validate the removal of old underground fuel storage tanks or assist in the classification of waste materials to minimise waste disposal costs. Because of our independence during these operations, clients and regulators alike are confident that the remediation solutions are pragmatic and implemented to meet or exceed program timings and limit costs.

Construction Inspection Processes 

When verification of a construction is required post-completion, or as part of a refurbishment or extension project, CGL’s has a proven track record of innovative solutions. 

Typical examples of our work include:

  • Exposure
  • Construction Inspection
  • Testing and measurement of existing buried or above-ground structures such as piled/shallow foundations or retaining walls

We can examine structures through physical exposure, typically by trial pitting, coring, or other techniques.

Sampling and testing of materials is also possible to determine the physical condition and remaining service life of a structure. Where appropriate, our experienced team employs Non-Destructive Testing (NDT) techniques including pile testing and more recently a boom-mounted 3D LIDAR – all techniques that allow construction inspection or investigation while avoiding various practical, physical, or health and safety constraints.

Expert Geotechnical and Geoenvironmental Engineers  

Geotechnical engineers at CGL are experienced in supervision of earthworks and the assessment of monitoring and compliance data from earthworks operations. 

Our experience and ability allow us to make immediate decisions that can avoid costly delays in the event of unplanned circumstances. Our pragmatic recommendations provide confidence that construction conditions are appropriate for the support of foundations, floor slabs, and sub-structures. 

Within the construction process, both contractors and developers can benefit from the capabilities and skills of our engineers alongside our independence which is valued and respected by regulators.
