Conventional, Plausible And Cost-Effective Earthwork Estimating
by Christa Jarvis
Estimating the volume of excavations is not an easy task. This is largely because you will be dealing with material that is not visible and you do not know what you will encounter before you start digging. The process of <A href="http://www.tchconsulting.com">earthwork estimating</A> is quite tricky but it needs not be.
Since you are using machines in a heavy job, a small breakdown can increase the downtime and lead to huge losses if the client decides to invoke the damages clause. The other unpredictable factor comes in form of rocks that you may encounter when you start digging. You also need to know about all electricity and utility lines prior to excavation to prevent damaging the existing infrastructure.
One of the worst mistakes you can make when quoting for such a job is to fail to account for other items that may come up in the course of operation. Since you may not know what will happen when the job begins, it is always important to keep your options open and discus with the client that in case the job requires extra hours when you find a rock, the estimate should be flexible enough.
Depending on the job, you might find that you may require doing a cut and filling if the soil removed is supposed to make up the levels of a particular area. Be sure to include the charges of spreading this soil in your final quote. Owning the machinery will save you from having to rent them and this can bring the overall cost of doing the job down.
You do not want to give discounts in areas where you will incur huge expenses and having software to highlight these areas will also help you to determine where you can lower your quote to make it more competitive and give you more confidence from tendering. The ability to interpret topographical maps will give you some insight when it comes to predicting the subsurface conditions.
Calculate the amount of hours you will require to complete the task and the cost of hiring the machines necessary to finish the work. Include other labour and fuel expenses and add your profit margins to arrive at a tentative figure. While it is the role of the contractors to locate the utility lines, it will be your responsibility to find exactly where they are and take precaution to avoid destroying them.
Even if you have been shown where the electricity lines are, of you break a water pipe that was not shown, you will still have to shoulder the cost. Plans may not be enough to depict the underlying conditions. Ask for cross sections that may show the presence of underground storage tanks or basement floors that you should know about before you begin.
Instead of bidding for jobs on a lump sum basis, it is wiser to calculate the quantities and quote for them based on cubic yards and the ratio of rocks to soil. A good engineer does not necessarily become a good estimator since they do not consider the swelling and shrinkage of soil. But they can help you when it comes to developing figures of rock and soil in terms of cubic yards.
