INDUSTRIAL The GEA team has designed a variety of specialized structures for industrial clients ranging from cement producers to ports and mines. Our design services cover geotechnical investigation interpretation complex foundations and ground improvement measures reinforced concrete structures and steelwork for crushers mills silos packing plants and ancillary facilities. We provide .
Geostructural At GEA we pride ourselves with our ability to marry structural engineering with sound geotechnical principles to provide designs thattake due account of ground-structure interaction. Our long-standing experience ranges from bored and driven piled foundations through soil and rock anchors to slurry walls and debris barriers with many points in between. We work closely
cold regions The GEA team has lengthy experience in the design of complex structures in cold regions such as power stations industrial plants and geotechnical structures feature prominently among our projects. With our in-depth knowledge of cold regions issues such as permafrost thermal regime protection foundations in arctic soils snow drift control and building envelope
Eurocan Pulp Mill is augmenting their plant with a steam-driven turbinegenerator unit. The turbine floor is 8 m above the ground level and is structurally separated from the pre-engineered exterior superstructure. A 50 m long pipe bridge carries process piping to and from the mill.
It measures about 40 by 22 m in plan and has a height of 33 m. The superstructure comprises lattice columns supporting trussed girders and roof beams. The upper 40 of the rear and sides is clad the rest is open. A 5 tonne bridge crane is provided. Concrete pile caps on ground

Most recent studies of the relationship between technological change and mining labour in the western metal-mining regions of North America have concentrated on the impact of the mechanization of the industry that took place during the second half of the nineteenth century. The distinct impression is left that the increased use of machinery especially the machine drill was the chief .
The finely ground raw material or the slurry is fed into the higher end. At the lower end is a roaring blast of flame produced by precisely controlled burning of powdered coal oil alternative fuels or gas under forced draft. As the material moves through the kiln certain elements are driven off in the form of gases.
