Dukwan weir, IndiaWe have been leading
projects and providing solutions in connection with dams and
hydraulic structures worldwide for 80 years. Our experience on a
variety of dam types, including concrete and masonry gravity dams,
and earth and rockfill embankments, has covered both new and
existing structures and we can offer a full range of
services.
One of our latest assignments is the Metolong Dam in Lesotho,
South Africa. This is a roller compacted concrete (RCC) dam that
when constructed will be 68m high and will impound a reservoir of
some 52 million m³ in order to improve water supply to the capital
Maseru.
Our global involvement in design and construction of dams includes
working in some of the most extreme conditions. For example, the
Kárahnjúkar hydropower dam in Iceland, for which we were lead
consultant responsible for all construction supervision and contact
administration; at 730m long and 200m high, it is one of the
largest concrete faced rockfill dams (CRFD) ever built.
Our first experience of large barrages was in the early part of the
twentieth century with some of the first major barrages on the
River Nile and Indus. Recent barrage work includes a comprehensive
study and design project for a major upgrade of the 810m long
Assiut Barrage on the River Nile, including the provision of a
hydropower station.
In addition to our increasing portfolio of international projects
we also provide a range of hydraulic engineering services to a
variety of UK projects. These include river engineering and flood
defences, dam safety and risk assessments, flood studies and
spillway upgrades, dam breach analyses and flood inundation
mapping, as well as the design of hydraulic control structures of
all types.
