Earthworks: Key Aspects and Average Salary

Earthworks form the foundation of any construction project. Without them, it would be impossible to prepare the construction site or ensure the stability and safety of the future structure. These tasks encompass a wide range of activities, from preparatory work and primary excavation to final landscaping. Earthworks play a vital role in the construction of family homes, industrial facilities, infrastructure, and other building projects. Common tasks in this field include digging foundations, soil transport and delivery, preparing bases for prefabricated houses, rock fragmentation, and soil compaction. Each project requires careful planning and expertise to guarantee the stability and safety of the structure.

Average Salary and Factors Affecting Pay

The average salary for workers in the earthworks sector in the Czech Republic is approximately 38,000 CZK per month. However, this figure can vary significantly depending on several factors:

Experience and Qualifications

Workers with extensive experience and specialized skills, such as operating heavy machinery or advanced rock fragmentation, typically earn higher wages. Professional qualifications and certifications for specific types of work, such as geodetic services or operating specialized construction equipment, can also lead to higher pay.

Geographical Location

Larger cities and industrial areas often offer higher salaries than rural regions, where construction activity may be lower. In areas with greater demand for construction work, competition drives wages up. For example, salaries in Prague or Brno are generally higher than in smaller towns and villages.

Project Type

Large infrastructure projects and commercial buildings tend to offer higher wages than smaller family homes or private structures. Projects requiring specialized techniques or greater coordination, such as bridges, tunnels, or large industrial facilities, often come with higher financial compensation.

Seasonality

Earthworks are often seasonal, which can affect job availability and wages throughout the year. During winter months, when work is limited by adverse weather conditions, job opportunities and wages may decrease. Conversely, in summer months, demand for workers increases, often leading to higher salaries.

What Do Earthworks Entail?

Earthworks consist of several main phases, including preparatory, primary, and finishing stages. Each phase involves specific tasks and requires various techniques and equipment.

Preparatory Earthworks

Preparatory tasks include all activities needed to ready the site for the main earthworks. This includes demolishing old structures, removing sod, stripping topsoil, and clearing trees and shrubs. These steps are essential for ensuring smooth progress during the main earthworks phase. Stripping topsoil is particularly important, as this soil layer contains nutrients vital for plants and must be preserved for later use in landscaping after construction is completed.

Main Earthworks

Main earthworks involve digging foundations, excavation, rock fragmentation, soil transportation, and compaction. These tasks form the core of earthworks and are crucial for ensuring the stability and strength of the future structure.

• Foundation Excavation: Proper foundations are essential for any structure. Before digging, geodetic surveying and site marking must be conducted. Construction machinery is then used for excavation and the digging of foundation trenches or construction pits.
• Excavation and Rock Fragmentation: About 90% of these tasks are performed using various types of machinery, such as excavators, diggers, and bulldozers. Manual excavation is usually supplementary (e.g., for final touches) or reserved for projects with minimal excavation needs.
• Rock Fragmentation: This activity often involves industrial explosives placed in sealed chambers (drill holes) and ignited with detonators. Blasting operations are demanding in terms of safety and are therefore entrusted only to qualified personnel.
• Soil Transport: Excavation generates spoil, which must be moved (vertically or horizontally) off-site and either stored in landfills or used directly for embankments, backfills, and infills. Landfills can be temporary or permanent, depending on the planned use of the spoil.
• Soil Compaction: Before using spoil in compacted embankments, the foundation must be prepared. This involves clearing vegetation, removing topsoil, or replacing unsuitable soil with more appropriate material. Compacted embankments are built layer by layer, with each layer spread longitudinally and compacted accordingly. Compaction methods are selected based on the properties of the material and the required compaction level.

Finishing Earthworks

Finishing earthworks include final landscaping, ensuring excavation stability, and preparing subsoil for subsequent construction phases. These tasks involve:

• Final Landscaping: After completing the main earthworks, fine adjustments to the terrain are necessary to prepare it for further construction activities. This includes returning topsoil, shaping the terrain, and preparing areas for planting vegetation.
• Ensuring Excavation Stability: Stabilizing excavations is critical for on-site safety. Techniques such as sheet piling, diaphragm walls, and excavation dewatering are used to prevent soil collapse and ensure stability during construction.
• Preparing Subsoil for Further Construction: Before beginning the next construction phase, the subsoil must be prepared for laying the foundation slab or other structural elements. This involves compacting the subsoil, creating a gravel bed, and preparing for utility network installation.
   

Ways to Increase Salary

There are several strategies that earthworks professionals can use to improve their earnings and enhance their financial standing. The most effective include:

Obtaining Professional Qualifications

Completing specialized courses and earning certifications, such as for operating heavy machinery or handling explosives, can significantly increase a worker’s market value. Certifications, such as those for handling explosives or surveying, can open doors to better job opportunities and higher salaries.

Gaining Experience and Practice

Workers with more experience and familiarity with various types of earthworks are often better paid. Offering professional consultations or managing projects can also be a step toward higher income. Experience with diverse project types, such as infrastructure, commercial buildings, or specialized projects, can further enhance a worker’s value.

Working on Larger Projects

Involvement in larger construction projects, which often offer better financial compensation, can be a way to increase earnings. Large infrastructure or commercial projects typically pay more than small family home constructions. Working on prestigious projects can also bring additional benefits, such as bonuses and perks.

Networking and Recommendations

Networking and personal recommendations play a significant role in the construction industry. References from former colleagues or supervisors can greatly improve job prospects. Participating in professional training and other industry events can help build valuable contacts and increase awareness of job opportunities.

Job Search: Key Resources and Tips

Finding work in the earthworks sector can be challenging, but several resources and tips can help professionals secure suitable employment.

Online Job Platforms

In the Czech Republic, several online job portals cater to earthworks professionals. Among the most popular is WeCan.cz, which offers a wide range of job opportunities in construction and earthworks and allows easy filtering by location, salary, and other criteria.

Recruitment Agencies

Recruitment agencies specializing in construction can assist in finding work in the earthworks field. These agencies often have up-to-date information about available positions and may also offer temporary job opportunities. Collaborating with a recruitment agency can be beneficial, as they can provide support in negotiating salary and other employment terms.
