Our services cover the entire process of preparing and executing works and facilities for construction and operation. The responsibilities related to contracts management include establishing the contractual and financial basis for the project, developing all tender and contract documentation for  a variety of types of project (conventional construction, design-build and EPC, operation and maintenance, private concession), managing the prequalification and tendering processes, contractual negotiations and award, and the complete management of all contractual issues during the lifetime of the implementation contract. For the technical supervision of construction and erection, our engineers and other specialists apply their long experience to ensure that the works are completed correctly, and wherever possible within the prescribed time with cost constraints, and all staff pursue rigorously the maintenance of quality throughout the project process.

Geological and geotechnical challenges are often very demanding when planning hydraulic structures. Hydropower, water supply and irrigation projects require detailed geotechnical investigations before the start of the actual design works. During planning and execution of the works continuous input by geological and geotechnical specialists is essential.

Geomatics play a major role in hydropower, land and water resources development as well as other infrastructure projects. Our worldwide projects require a wide range of approaches to the integration of different types of spatial information. To meet these needs experts with various qualifications, offer expertise in engineering surveying, geodesy, geographical information systems, remote sensing, land administration and cadaster.

The planning and development of projects in the water sector require comprehensive information ideally based on reliable observation networks. We analyze meteorological and hydrological data and apply statistical methods and simulation models to derive streamflow hydrographs and flood discharges required for the design of dams and hydropower plants. Hydrographs include not only the assessment of the preceding data, but also the impact of future climate change on the particular project.

For construction management, we determine the most efficient river diversion scheme and model and supervise the reservoir impoundment process. We simulate and optimize reservoir operation for isolated reservoirs or integrated reservoirs systems, considering multiple objectives such as hydropower generation, irrigation demands, ecological needs, flood protection and sediment management.

Inflow forecast as well as advising and updating of operation rules complement our services covering the full range from initial studies to commercial operation.

Through our highly experienced partners with their specialist Engineers, we provide training and support for the permanent operation and maintenance staff of hydropower and water control facilities, including general and specific operation activities, inspection and surveillance of the facilities, maintenance and repair programs and procedures, as well as the development of reservoir operating rules for the optimum use of water resources, and the design of instrumentation systems and monitoring programs.

We perform the planning, design and contracting for the manufacture and erection of hydromechanical, mechanical and electrical equipment in hydropower plants and other hydraulic structures, as well as the supervision of the entire process including factory acceptance tests, handling and erection on site, testing, quality control and commissioning. In addition to new projects we have extensive experience in the rehabilitation of existing plants.
