There is no way you can have a well-organized construction site all the time with the dirt well sorted out and you should not do all the cleaning on your own when there are professionals to help. You may not keep the site on a top condition all the time but you should not have to put with a dirty place either waiting for the work to be over in order to do a professional cleanup. It is wise to hire regular cleanups throughout the project so that when the work is finally done the cleaning job will not be overwhelming. You will reduce the amount of money you spend in getting the site in order if you hire the professionals on a regular basis because the place will not be too dirty to the point where they take hours to get it organized. You need the workers to be working in a safe environment to avoid run-ins with occupational health professionals. You should avoid getting on the wrong side of the law because no one needs the cases and expenses that can follow.
If you cannot make a conscious choice to make the working conditions better for the people working for you then you are not a good boss. You should avoid being smug to the point where you can just replace your workers if they complain about a bad working environment. When workers keep quitting, more resources will go into finding and hiring new ones instead of concentrating on the project at hand. When you keep the environment clean all the time, the workers are going to focus on getting the work done hence you will get a great output, and you also benefit from not having to throw in resources into the recruitment process every few days.
Dust and even dirt are not good for human health and you will be jeopardizing the health of your employees by making them work in such conditions. You will have no option than to compensate them when it is determined they fell sick as a result of poor working conditions. Also, it is common for nails and other sharp items to get scattered in a construction ground. This is why regular construction site cleaning should be conducted to get rid of this because it will be a different story if they do hurt someone. Also, working in a clean environment increases productivity and you cannot bargain with this. This is exactly what you need because as long as the construction is ongoing you will be piling up the expenses.
