A Testimonial

So, you’re looking to have some excavation work done in Worthington or the surrounding southern Minnesota region. Great! Well, maybe it’s not so great. Perhaps you had a bad experience working with excavating contractors or just don’t know enough about what’s involved with a project.

excavating a leaking fuel tank

I know where you’re coming from. I was in the dark when we hired an excavating contractor to plan a dig to bury a large diesel fuel container on our property. I didn’t know the right questions to ask the planner and didn’t know any of the danger signs to look for during the dig. I more or less just let them “do their thing”.

It turned out the project supervisor didn’t oversee the entire project, the fill-in crew didn’t use the right compact material or backfill method, so the fuel tank settled wrong and developed a leak. Thank God the environmental damage was minimal and, thousands of dollars later, we finally got the site cleaned up.

Worthington Excavating has the care and expertise to get your project done right the first time!

This website was built so you won’t have to go through the type of experience described above.

This site provides the information you will need to make the right decision when choosing a Worthington excavating contractor to run your digging, clearing or grading project.

There are a number of projects that excavation contractors can perform. These include digging for a sewer system, foundation excavation, driveway grading, trenching, demolition, landscaping, site preparation, road excavation and more.

Whatever construction project you have that will require a Worthington excavating contractor, you’ll want to get informed about what’s involved in planning for your project, what to expect from your newly hired excavating company and what steps are required for your particular job.

We’re here to help you sort that out so when you’re ready to hire an excavating service, you will know your contractor will do the job correctly and take the right steps to ensure the job site environment is protected.

Here’s What You Should Know:

Planning Your Excavating Project – Pay Attention to Site Work Setup

The construction supervisor needs to make the major decisions for planning the construction project and staging the equipment. Make sure these decisions are not left to the excavation foreman because he doesn’t know the full scope of the project. The foreman’s job is doing the work, not planning the project.

There are many requirements a Worthington excavating supervisor needs to consider for each phase of the construction work.

Insure the excavation project plans you approve include the following. This will avoid costly mistakes, wasted time and harmful environmental damage:

  • Foundation
  • Where site utilities will be located
  • Where equipment and materials will be stored
  • How soil erosion will be handled (see more below)
  • Locations of topsoil and fill piles
  • Rock removal
  • Brush, tree and tree stump removal
  • Dewatering plan
  • The roads used for hauling
  • Building layout points
  • Parking area for workers
  • Office trailer location

Clearing Brush and Trees in the Work Area

It’s more complex than it may seem. This is the first process performed when starting your project and it needs to be done right the first time. It makes the soil ready for topsoil stripping and bulk excavation.

See that your excavation specialist has the required permits for removal and disposing of brush, trees and tree stumps. Find out what disposal methods will be used.

For example: If the excavator operator is planning to simply bury tree stumps or logs, this can cause major settlement problems later if not buried in the proper location.

The construction supervisor also needs to plan for changes in soil conditions after trees and shrubs are removed.

Understand the Demolition Requirements Before the Digging Begins

The methods used in the disposal of man-made materials from your worksite can be complicated and often increase the cost of the project budget.

Materials may include metals, piping, asphalt, concrete, glass, wood, etc.

The excavator operator should know if there are hazardous materials in the demolition such as lead paint or asbestos, and take the necessary steps to make sure they are removed by a qualified, licensed professional.

Make sure the Worthington excavating business doing your project has the proper permits for all the materials that will be removed from your property. Make sure they are clear on exactly what is to be demolished and the limits to which those items will be demolished. Know the intent of the demolition work being performed. Find out what the proposed finished look of the site will be before the work begins.

About Erosion and Sedimentation on Your Property during an Excavation Job

Erosion has been a costly issue on many excavation jobs. Poor site preparation and erosion control have caused streams to become filled with sediment and flood. The sediment also lowers the quality of water used for municipal or industrial applications. And, it destroys lawns, clogs city drainage and injures fish, to name a few.

Ask your dig planner how they intend to control erosion on your property during the excavating process.

This may involve grading or digging only in the areas where your construction is taking place and reducing the places where bare soil is exposed.

Controlling erosion caused by excavation construction may require installing subsurface trench drains to divert water to the desired location. Another way it can be controlled is by planting vegetation. Sod, for example, can be inserted in the area to reduce erosion almost immediately. Permanent seeding is ideal.

What You Need to Know About Excavating Rock

There are many solutions for rock excavation and the methods used need to be reassessed during the project because of the way the site conditions will change during the dirt removal process.

You as the property owner need to decide whether or not to test for sub-surface rocks and what to do with above surface rocks and those found during the excavation process. There may already be a geotechnical report available for your property. If not, you can get a test pit dug, get some percussion drilling done or do core drilling. Each of these testing methods increase in pricing but also increase the accuracy of data that’s collected.

Knowing the location before excavating rock will help the Worthington digger plan the steps and processes needed for the overall project.

It’s also important to note that the excavation manager should be aware if this is a classified or unclassified excavation. If it’s unclassified and the Worthington contractor finds rock during excavation, he is responsible for removal as part of the construction contract price. If classified, the owner is responsible for the additional costs for the quantity and size of rock removed. The pricing structure should be determined before digging begins.

The excavation construction planner needs to know if you’ve done any testing for rock and agree to do either an unclassified or classified excavation.

Water WILL Affect the Work Site

Rain can turn a dry construction area into a mud hole. The amount of damage rain can cause will be determined by the advanced planning of the excavation company you hire. Be aware that, as part of your excavating project, part of the contract costs will involve dewatering the area with pumps, deep wells, wellpoints, trench drains, siphons, cutoff walls, and/or grading. And, these costs can take a huge chunk out of your budget.

Estimating the cost of dewatering is very hard to do because of soil conditions, rocks, groundwater location, the dewatering method used, the time needed for dewatering and site cleanup.

Be sure to discuss with your excavation planner what the plans are for dewatering and what the costs might be for this process.
