Water Management Specialists servicing the World Wide Construction Industry

City, University of London established a close working relationship with OGI to bring industry experts together with MSc students to enable them to better understand the complex issues associated with groundwater control.
This was made possible because OGI developed a specialist educational facility allowing students to benefit from hands on dewatering on a two-day residential course held at OGI headquarters.
The course was expertly run, & student feedback was always extremely positive. This unusual and probably unique opportunity was a highlight of this specialist MSc.”

OGI was engaged on a major gas pipeline river crossing (5km) to support the conceptual groundwater design of the shafts & tunnel. Groundwater posed a significant risk to the environment & to the health, safety & welfare of the construction workers.
OGI devised an innovative test using the existing boreholes & data loggers to develop & refine the conceptual model.
This was completed on time & at substantially less cost than the full pump test, providing suitable data to allay key stakeholder concerns.”

I always think that the sign of a real expert is confirmed in their ability to communicate in a manner that is understood by the intended audience.
OGI communicated to all parties using succinct & confident language.
They then delivered proposals to gain the confidence & support of the client & other stakeholders. OGI’s solutions were both innovative in their development, & practical in their implementation.”

Their professional approach & expertise resulted in a dewatering system that ensured the safety of personnel & maintained progress on the deep excavations and groundworks.
OGI were excellent at guiding us through the regulatory obligations required to complete such a dewatering scheme & liaising with the statutory organisations.”

Particular recognition can be made to OGI’s ability to develop a mathematical model of the groundwater behaviour surrounding individual structures and over the entire site.
This enabled OGI to predict the impact of their designs ahead of the system installation, giving confidence to all parties that the water management system would reach their overall objectives.”

OGI consistently demonstrated their technical knowledge and substantial experience in practice. OGI was able to use their innovative mathematical modelling capability to simulate ground & groundwater conditions ahead of the implementation of any design.
This enabled us to minimise the impact on our crowded site with many other operations taking place simultaneously, & gave confidence that the designs would successfully achieve its objective. OGI’s ability to use this modelling skill to articulate the wider impact of our activity, provided surety to stakeholders of adjacent infrastructure & resources.”

OGI were able to demonstrate & clearly present through the use of innovative techniques and modelling software, the complex relationships between water flows & pressures during different stages of excavation.
Also, by analysing data from the TBM drive they showed how these could be influenced by tidal cycles.”

We have found that OGI stands out in consultancy services in respect of their depth and breadth of knowledge in modelling & design of groundwater control systems.
This all-inclusive approach adopted by OGI fosters a level of confidence that we find so reassuring & we believe is unique & innovative in this industry.”

I have had the pleasure of working with the OGI team on several projects & what has always impressed me is their ability to reduce a problem to its simplest components & then come up with an elegant & inexpensive solution.”

The service provided by OGI is always tailored to suit the needs of the individual site & is delivered with an exceptional degree of professionalism.
I have worked with OGI on several other schemes & their innovative ideas in both geotechnical engineering & dewatering have provided us with a competitive edge.
Dr Stephen Thomas & OGI are clearly experts in their field & as such are first choice for my company when we require a dewatering solution.”
