Have you been at any excavation site before? If yes, how does it look like? This is just the sample of how a typical excavation site should look like.
It has become a normal practice for most construction jobs to be done with little regard to the safety of the workers, machines, and the environment yet no serious penalty will be charged to the offenders. It takes a qualified and experienced personal for sound techniques to be used during construction jobs.
Excavation is one of the major activities that do occur at any place mapped out for building of any project either by the government or individuals. The sole aim of excavation is to obtain a uniform level of the ground before mounting structures on it. Other reasons for excavation in the construction would be to bring out a large volume of soil so it can be used to fill another hole, or for foundation filling, besides other uses excavation also finds its use in the mining industries such as gold mines, coal mining and diamond mining, etc. the activity is very vital in obtaining many solid minerals from the ground.
The problem of excavation has been mostly based on the solid nature of the soil that such action would take place. According to a truck driver, he explained that he prefers conveying solid dry sand than wet muds or wet sands because they are lighter to convey than the wet types and if the load he is carrying is heavy it will have great effect on his driving strength and impose more risk of accident for him.
I had witnessed several excavation works including the making of water drainage system which also requires the excavation activities but I can say that only few apply safe strategy in ensuring the safety of personnel involved in such activity. A situation excavation job is carried out after a heavy rainfall will definitely require a good safety boot and dry leather hand groves for effective gripping of objects and avoiding of the slippery nature of the soil that could cause serious fall to the personnel working, but in some local construction sites such is not the case, to them excavation can be carried out at any weather condition without full regard to safety implementation.
The picture above can be referred to as a good example of professional practice in excavation activities, such that the following were put into consideration:
WORK OUTPUT PER HOUR
Work output simply means the quantity of work to be done within a specific period of time, a good construction industry will always measure its work output and use it to estimate the needed hours for the remaining parts of the job and the only way to increase this work output is by using machines with big sizes and rigidity in carrying out its functions, that is just what is visible when you take a close look at the excavator shovel which has such large size capable of excavating about 4 wheelbarrow of soil per action. While the truck was meant to carry enough volume of excavated sand such that few trip of the truck will give a good work output for the day, and will also reduce the stress of driving to its driver.
The safety of the workers were putted into consideration since they were working under the shelter of the two vehicles and anyone standing within had been asked to give a good distance from this location because of the swinging actions of the excavator which may hit anyone nearby in the event of any mechanical failure and such incident will lead to fatal accident and death, so ensuring no one is within the space is a good sign of safety for personnel.
When there is division of labor in machines it helps in sustaining the lifespan of the machine, some local construction industries wouldn’t mind using the excavator to convey the sand directly to area it is needed without the use of any truck. The truth is that it may cut the cost of hiring the truck but it will give high stress to the excavator and as a mechanical machine operating with hydraulic fluids using it in such manner may result to mechanical failure. It is always good to consider the machine durability in any engineering work because a damaged machine is like an injured worker, you will spend money for repair and count lost time of work output just as you will pay treatment bill and count lost time of work output in any injured worker.
The space provided for swinging and the condition of the excavator and the truck made the working environment conducive for them such that none of the workers were affected by direct sunlight or rainfall during the work.
The environment is secured from any intruding following the manner the job is carried out and how the truck and excavator is positioned. The only non-visible thing in this picture is a barricade that supposed to sound as warning for anyone entering into the working space.
