As co-authors of CIRIA C750 Groundwater Control: Design and Practice, we take pride in our extensive design capabilities. Our proficiency extends to 2D and 3D computer modeling, ensuring precision and effectiveness in crafting dewatering solutions tailored to your project’s unique requirements.
Conducting thorough pumping tests allows us to intimately understand site conditions, providing valuable data for cost-effective installations and optimised program timelines. This not only reduces operating costs but also validates the original design, instilling extra confidence in both budgets and project timelines. Our commitment to comprehensive site understanding sets us apart in delivering efficient and reliable solutions.
In the pursuit of optimal dewatering solutions, we implement a spectrum of sophisticated techniques. Empirical optimisation, grounded in extensive experience and industry-established ‘rules of thumb,’ enables the fine-tuning of dewatering systems. Observational optimisation relies on on-site observations, particularly monitoring drawdown versus flow, providing invaluable insights for troubleshooting when ground conditions deviate from expectations.
Analytical optimisation employs precise analytical equations to estimate essential parameters for system design. Furthermore, numerical optimisation harnesses available data to populate intricate 2D and 3D models, facilitating a comprehensive analysis through a series of refined and simplified techniques. This comprehensive and strategic approach ensures the customisation of solutions tailored to the distinct requirements of each project, reflecting our commitment to professionalism and excellence..
