The bearing capacity of of soil is an important consideration in construction projects. The bearing capacity of soil is the pressure that a soil sample can support without collapsing. Bearing capacity varies with different soils cohesion. Cohesion is the force that holds together molecules and particles inside soil.
Rock is a continuous mass of solid mineral material, such as granite or limestone, that can only be removed by drilling or blasting. Rock is never completely formed of a single large segment, but is crossed by a system of joints that divide it into irregular blocks. Despite these joints, rock is generally considered the strongest and most stable material on which a building can be founded.
Soil is a general term referring to earth material that is particulate. If an individual piece of soil is too large to lift by a singular hand it is considered a boulder. It it takes the whole hand to lift a particle, however, it is a cobble. If a particle can be lifted without difficulty with thumb and forefinger, the soil is classified as gravel. If the individual particles can be viewed but are too small to be picked up individually, the soil is known as sand. Both sand and gravel are coarse grained soils, meaning at least half the material is retained on a Number 200 sieve.
Peat, topsoil and other organic soils are not reliable for the support of building foundations. Due to the high concentration of organic matter, they are spongy and are easily compressed. Their properties can change over time due to changing water content or biological activity in the soil.
Clay soils are usually referred to as very cohesive, as they retain a measurable shear resistance (a materials ability to resist forces that can cause the internal structure of a material to slide against itself), in the absence of confining forces. The ability of a cohesion-less or frictional soil such as sand or silt to support a building depends on the friction between its particles. Sand confined by surrounding soil within the earth can support a heavy building, whereas a conical pile of sand on the surface of the earth can support nothing, because there is little or no shear resistance between the particles.
Beneath every building site lies a number of superimposed layers, also known as strata, of different soils. In ancient times, the actions of natural forces allowed for the deposition of the strata one layer on top of another.

Risk Management in Construction Projects Essay

- Risk management is a process used in all industries to reduce the risk. The Risk management tool usage changes from sector to sector and hence each sector has developed their own risk management tools and methodologies to mitigate the risk. But the concept remains the same behind all the tools (Ropel, 2011). The main steps for risk management irrespective of the sector are: 1. Risk Identification 2. Risk Assessment 3. Evaluation of the risk 4. Steps to mitigating the risks 5. Regular monitoring and review of the risks Here we will discuss risk management in the construction sector and in execution of construction project, project risk management is one of the most critical phase for succe...   [tags: construction sector,risk evaluation,monitoring]

Software Design And Construction Projects Essays

- A project is not considered like an ordinary work on daily basis but it is described as work that is done on certain occasion (Field and Keller 1998). However, some of the fields that are related to research, software design and construction are highly related to projects. According to Buchanan and Boddy (1992, p.8), a project has a beginning and an end that is conducted by people to achieve the same goals within a budget constraint, time frame and quality of work. Lewis (2000, p. 4) defines a project as a one-time, multi-task job that has clearly defined starting and ending dates, a specific scope of work to be performed, a budget, and a specified level of performance to be achieved....   [tags: Project management, Management, Risk management]

“The relative proportions of particle sizes and different types in a soil are important to know when designing a foundation because they are helpful in predicting the load bearing capacity of the soil, its stability, and its drainage characteristics,” (Allen and Iano 22).
Cohesion is significantly modified by the water content. If there is an increase of water, the cohesion of the soil particles may decrease in soils such as clay. This is because the clay particles are separated by the increasing water content. This causes softening of soil cements.
Piles can be used to find soil bearing capacity. If a pile is driven until its tip encounters firm resistance from rock, dense sands, or gravels, it is an end bearing pile. If it is driven into soft material only, without encountering a strong bearing layer, it will still develop a considerable load-carrying capacity through the frictional resistance between the sides of the pile and the soil through which it is driven. This is known as a frictional pile.
Piles are driven close together in large groups. The piles are connected at the top by a reinforced concrete pile cap. This allocates the load of the column or wall equally among the piles. “End bearing piles are used on sites where a firm bearing stratum exists at a depth that can be reached by piles. Friction piles are used when no firm bearing stratum exists at a reasonable depth or when a high water table would make footings prohibitively expensive.” (Allen and Iano 46).
Loadbearing capacities of piles are determined in advance based on soil test results and the properties of piles and piledriver. To confim the accuracy of the calculation, test piles are often driven and loaded on the building site before foundation work begins.
