Construction Estimating

For many excavating contractors, the costs involved with excavating and earth moving often seem to be much more than they originally anticipated. Sometimes, this can result in lost profits, unsatisfied clients, or even unfinished projects. An understanding of excavating estimating is crucial for anyone involved in earthmoving and construction.

Inaccurate excavating estimating is responsible for most of the financial losses and struggles of contracting businesses. Because an excavating project entails so many different things, assigning the right costs to these jobs can be difficult. The best way to ensure accurate excavating estimating is to always see the actual job site before determining the project costs.

You can also use the assistance of topographical and contour maps, survey reports, and the actual site plans, but it is important to remember that there could be errors in any of this data and they should be used as guides as you explore the excavation site. The first thing to consider for excavation estimating is the amount of dirt you will actually be moving, measured by volume in cubic yards.

There are several different formulas and methods that can be used to determine this number and it is important for your calculations to be accurate if you want an accurate excavation estimate. Start by defining the excavation site's boundaries and calculating the area in square feet. Once the area is figured, it will be multiplied by the depth of the earth in the excavation site to calculate the volume.

There are a number of different scenarios that can create difficulties in accurate excavating estimating. Some sites may have a great deal of debris beneath the dirt's surface, making the excavation more time consuming and increasing removal costs. Unmarked ravines or wetland areas of the land may interfere with the excavation procedures. A number of other instabilities and natural land characteristics can interfere with excavation cost estimating as well.

Because there are so many different factors involved in estimating excavating projects, there are several excavating software programs and books that can make the task much easier. Construction and excavating estimating software will generally use a standard, average rate to figure each of the costs involved in the project so you can figure a more accurate estimate.

While these estimating assistants can calculate a rough cost for labor, materials, and even equipment, there are still a number of things that you must be aware of for a successful project. You will always have to calculate the volume of dirt, even if you are using excavating cost software, and you should always adjust the overhead figures provided to accurately reflect your own costs.

It is also good practice to develop a system for calculating job costs. An organized way of factoring in various aspects of the complete job costs can make it easier to estimate each individual excavating project. Regardless of the maps, survey records, and other data you may have available, always visit the job site, examine the soil levels and terrain, and do your best to access the actual work involved with moving the land for the most accurate excavating estimating.
