Senior Engineer & Technical Lead
Rod has been responsible for leading the technical team modelling schemes, producing cost comparisons and determining Return on Investment as well as utilising GIS skills to produce a number of systems with Hydro.
As the lead technical expert at Hydro Consultancy Rodrigo has undertaken the fluvial modelling of two main rivers, in support of Arup, to inform the design of HS2 infrastructure in Birmingham. He is responsible for the design and modelling of solutions for the sustainable management of water resources plus he assists in the development and maintenance of client relationships and in the efficient management of people resources.
With over eight years of international experience working in the fields of hydrology, hydraulics and water resources management, Rodrigo contributed to the development (from feasibility study through to construction) of several different types of water related projects, including: flood risk management schemes, hydro-power projects, regional irrigation schemes, sewerage networks, sustainable drainage systems and water supply networks.
From 2003 to 2007 Rodrigo worked for a Portuguese consultant that was a leader in the fields of hydraulics and water resources, where his main responsibilities were to prepare and review hydrological studies, hydraulic designs and models and long term economic appraisals for water related projects, as well as leading the production and delivery of the associated technical reports and drawings.
In 2007 Rodrigo joined Arup at their Midlands Campus, quickly becoming the lead designer and hydraulic modeller in the Flood Risk Management team and assuming responsibility for all the tasks required to design and model flood risk management schemes and sustainable drainage systems. This included the procurement and supervision of topographic and CCTV surveys, building and validation of hydraulic designs/models, preparation and review of technical reports and drawings and liaison with clients and key stakeholders.
At Arup Rodrigo was also responsible for the preparation and review of Flood Risk Assessments (FRA) in accordance with current legislation and for the long term economic appraisal of flood risk management schemes in the form of Project Appraisal Reports (PAR).
