The retaining wall should have a strong foundation to satisfy the stability criteria. The foundation can be made stronger through the use of strong reinforced concrete and use of the bent foundation slab (Ambrose 2009). The retaining wall structure will be stable as long as it satisfies these criteria.
Given the topography and the environmental constraints on the road, the use of extensive retaining structures is paramount to try and reduce land and take impact on sensitive areas of the road. It is estimated that over 115km of these structures are required to support the road structure required (Crosbie & Watson 2005).
The construction of Valleys Road between Gilwern and Brynmawr (section 2 of the project), will involve the widening of the road. This will affect the slopes on both sides of the road. This current project is focused on designing of retaining wall along Valleys Road. The project has been laid out on the project plan.
The poor visibility by the motorists plying the route hence contributing to the many accident cases that were being witnessed every now and then on that road.

Ships that operate on this type of engine have a higher speed that saves on the cost. This is because they have a big diesel turbine whose operation consumes little amount of fuel and more of the horsepower for long travels. The propulsion machine in these ships is charged electrically and that’s why it is referred to as combined.
Diesel doesn’t have fuel within their cylinders prior to combustion. Therefore it is possible to have the cylinder loaded with 1 bar or more of air without necessitating pre-ignition. Turbocharged engines generate bigger volumes of power than normal ones. More air within the cylinder causes combustion of more fuel hence more power production.
