OGI has more than 20 years experience in providing groundwater related services to clients and contractors in the United Kingdom. We supply consultancy and specialist contracting services for some of the most challenging natural ground conditions encountered by the construction industry.
Our solutions are delivered using unique specialist design techniques and in-house developed software. The solutions are implemented by an experienced field team within appropriate Health and Safety procedures.
The three principle areas of OGI’s work are in the field of Construction Dewatering, Ground Source Energy and Computer Modelling. For more on our services please click on the following links:
Construction Dewatering
Incorporating design and installation of deep groundwater abstraction boreholes for the purpose of lowering the water table and reducing artesian water pressures to ensure a safe and stable excavation thereby allowing underground construction.
Ground Source Energy
Design and installation of both deep and shallow ground collector systems, together with the integration with other heat sources, to ensure a safe and sustainable ground energy supply to a ground source heat pump. OGI also designs the internal heat pump system thereby ensuring that sufficient heat energy is provided to the building.
Groundwater Modelling
OGI has a unique capability to provide real time computer modelling solutions to the field work teams. We have developed in-house software for the simulation of groundwater flow, heat migration and contaminant transport within a porous aquifer.
Geotechnical modelling
OGI has capability and experience within modelling and providing design inputs for the calculation of earth slopes, retaining structures and other construction-related effects.
Both standard engineering methods and state-of the art numerical methods are available to achieve an optimum safe and standard compliant design.
Linking the design of temporary structures with the design of construction dewatering together with the on-site observational approach taken, OGI can deliver additional benefits.
