The dock is a spot you may spend lots of quality time with friends and family. It is where you may expect people to not only walk, but also run or jump on it. That is why the dock has to be strong and stable enough to endure all of this. The last thing you want happening is the dock collapsing because of poor or a weak piling. And the best way to prevent this is through a strong and appropriate dock piling installation. It has to be done in such a way that it will be able to last through years of bad weather and marine degradation. There are three main ways to install dock piling.

Bored pile also referred to as drilled shaft at some places is a kind of reinforced-concrete base that holds frameworks carrying heavy vertical loads in place. A bored pile is basically the concrete cast-in-place, which means that the pile is cast on the site of the building. The arrangement varies from other concrete foundation designs, such as spun pile or reinforced concrete square pile foundations, which make use of concrete precast platforms. Bored piling is used extensively for bridge construction, tall buildings, and other large industrial projects, which all require deep and intensive bases. Apart from the foundation systems, Bored piles are also used to build formative underground barriers for earth retention. Piles may be stacked next to each other, with 75 – 150 mm gap in-between— referred to as contiguous pile wall, or they can be positioned in a way that they coincide, creating stable and robust fencing, often used to regulate groundwater movement.

Geothermal energy is the second most abundant source of heat on earth, after solar energy. It is the natural heat energy stored in the earth. This energy is contained in about 260 billion cubic metres of rocks and metallic alloys, just below the outer surface of the earth, that are at or near their melting points (Lanterman & Lee, 2007). Calculations show that the Earth, originating from a completely molten state, would have cooled and become completely solid if the only energy input was that of the Sun, so it is believed that the ultimate source of geothermal energy is the decay of naturally radioactive isotopes (Dincer et al., 2007). The thermal energy from the earth continuously flows outwards. This heat transfer from the core to the surrounding mantle is principally via conduction. When the temperature and pressure of the system becomes high enough, some of the rocks that make up the mantle melt and form magma. As the liquid magma is less dense than surrounding rocks, it slowly rises, convecting thermal heat towards the earth’s crust (Lanterman & Lee, 2007).
