Excavating Companies

Whiterock Ventures have experience in handling projects involving earthworks, environmental remediation, oil sands road building and stockpiling of aggregate. Excavating companies do much more than only soil and aggregate hauling. In Edmonton, our services are wide but there are added responsibilities on site that we need to handle with our work. Our additional responsibilities include:

  • Site Preparation: In a typical residential construction project, the excavation contractor shows up after the surveying crew determines the house and lot boundaries. The contractor removes the soil to the depth required for the new foundation and ensures that the soil is firm through compaction tests and compaction with equipment, if necessary. The dig requirements are precise, so the excavation contractor must be able to use a level and transit to match the grade posted by the surveying crew. After the foundation contractor pours the footers and stem wall, the excavation contractor backfills around the new foundation.
  • Contracting: Excavation contractors are business owners and are considered subcontractors because their job is often just one part of a larger project. A homeowner can contact an excavation contractor for a personal job, such as digging for a swimming pool, but the excavation contractor won’t oversee the entire project. Excavation contractors often work under the direction of general contractors, who solicit bids, coordinate subcontractor timelines and pay the excavation contractor when he completes his part of the project.
  • Moving Dirt Around: If it has to do with moving dirt, an excavation contractor is probably the guy to do it. Depending on the equipment the contractor owns or leases, he can build roads, grade roads, dig ponds and sewers, excavate ditches for water lines or gas lines and operate trenchers that install flexible pipes beneath the ground without creating ditches. Excavation contractors create terraced drainage on agricultural land and build earthen dams.
  • Heavy Equipment and Operators: Excavation equipment is expensive to purchase and costly to insure. On average, a small to mid-size excavation contractor will often own or lease a couple of large front-end loaders, bulldozers, backhoes, compactors, trenchers and skid steers. Most excavation contractors also own large dump trucks to haul away excess dirt. College or trade school degrees in heavy equipment operation are few, so most contractors will hire skilled operators or new operators and train them on-the-job. Many excavation contractors are prior heavy equipment operators.
  • The Business End of Excavation Contracting: The excavation contractor must submit competitive bids and estimates and must know the going rate for excavation work in his community. In most states, the contractor must be licensed and bonded, which might require taking a skills and knowledge test and providing evidence of financial stability. The contractor establishes a bookkeeping and payroll system and usually pays income taxes quarterly.
