The grading contractor operates a piece of heavy construction equipment called a grader for leveling roads or building foundations. The work of the graded contractor is very dirty and must work in all weather conditions.
Responsibilities of grading contractors
Grading contractors operate in the construction industry and provide site development services for commercial, industrial, and residential projects. In addition to digging underground buried objects and leveling construction sites, grading and excavation contractors also obtain relevant licenses and permits to perform their work and ensure the safety of workers and the environment.
Site Investigation
The grading contractor inspects the project site to study and analyze various conditions, including terrain slope, soil type, distance from human or wild animal populations, and underlying facilities or structures. Use this information to develop an appropriate plan to organize the work, determine the most suitable machine for the job, and estimate the number of workers required to complete the work within a specific timetable.
Obtaining permits
Before starting work on the construction site, the grading contractor must obtain an excavation permit from the appropriate state or local agency. Although excavation regulations vary from state to state, these contractors usually submit a request describing the scope of the project to the regulatory agency for approval. When a company needs to inspect the excavation site, the grading and excavation contractor is usually present to answer any questions that the inspector may ask.
Site development
After obtaining the necessary excavation permits, the excavation and grading contractor began to develop the site. They use their own experience and professional training to determine the best way to excavate. For example, in a bridge construction project, the contractor first cleans the ground of any factory, and then uses heavy machinery such as backhoes, cranes, and hydraulic compact excavators to dig dirt or rocks and create trenches or holes of the required depth. The contractor classifies the site according to the project design to achieve a level foundation to lay foundation.
Equipment excavators used by grading contractors:
Generally, several equipment are used for removing debris and vegetation from the soil (cleaning, planning, and cleaning), excavate the soil from the loan area, cut the transportation road, spread the poured filler, tear the rock and press Solid soil.
Scraper: The scraper is used to dig (scrape) soil from the loan area, transport it to the site, and pour it on site. The rubber tires of the scraper can be used to compact the soil. Push-pull scrapers can be used in tandem to provide extra power for digging hard or soft rocks.
Loaders– Similar to scrapers, loaders can be used to dig soil from the borrow area, transport the soil, and then compact it as a structural filler.
Excavator: This type of equipment is very suitable for digging narrow ditches for public facilities such as storm drains and sewers. The equipment is also used to excavate foundations and other basic elements.
Dump trucks -If the loan location is far away from the site, you may need to use dump trucks to transport the borrowed soil to the site. Dump trucks are also needed to transport soil or import selected materials on public roads.
Conclusion
Grading contractors are responsible for the safety of the project, workers, and the environment. To this end, it hires workers with relevant construction experience, organizes training programs to improve their skills in operating excavation and leveling equipment and machinery, and ensures that those exposed to hazardous conditions wear personal protective equipment, such as those with puncture-resistant soles,boots, helmet, earplugs, and face mask at all times. The grading contractors in Edmonton have also developed strategies to prevent soil erosion, such as building silt fences to capture eroded soil.
