Road and Bridge Design and Construction Services – Complete Solutions with Dromcons

Behind every bridge we see, there’s a team of specialists who check, measure, and ensure everything is done correctly. Building a road or a bridge is a huge responsibility, as thousands—or sometimes even tens of thousands—of people will use it daily. That’s why there is no room for errors in the design or execution of such structures.

Safety is the most important criterion, and achieving it requires rigorous testing, complex documentation, and flawless execution. With over 21 years of experience in road infrastructure design and construction, the Dromcons team stands out through a complete approach, where execution quality and people’s safety are absolutely essential pillars.

Road Design – From Plan to a Safe and Durable Reality

Design is the first step in any road infrastructure project. In this section, we’ll discuss road design, followed by bridge design.

During the design phase, engineers put everything on paper (and later into specialized software): slopes, structural layers, drainage solutions, traffic safety, and environmental integration. Dromcons is a road construction company that strictly follows these steps, and before moving into execution, it firmly asks: “Can a safe and efficient road be built here?”

Our team of engineers answers this question through careful studies and detailed land assessments.

When it comes to documentation, at Dromcons the process involves two main categories: graphic documentation and written documentation.

Graphic Documentation in Road Design

• Site plan – shows exactly where the road will be located, how it connects with existing areas, and how it integrates into the environment.
• Zoning plan – demonstrates how the project complies with urban and environmental regulations.
• Execution details – technical sketches that builders need to follow each stage.
• Longitudinal profile – describes altitude variations along the road, crucial for slopes and drainage.
• Cross-section profile – shows the layers and widths of the road to ensure safety and comfort standards.

Written Documentation in Road Design

• Technical report – explains, in clear terms, why specific technical solutions were chosen.
• Specifications – define the rules for execution: materials, methods, quality standards.
• Control program – establishes how and when works will be inspected.
• Cost estimates – give the client a clear picture of the budget by category of works.
• Requests and approvals – the Dromcons team handles the entire bureaucratic process, saving the client time and making everything easier.
  
  

Bridge Design – Structures That Withstand Time

If designing a road already involves high complexity, designing a bridge requires even more attention. In this case, safety and durability are paramount, as these structures must withstand heavy loads and harsh weather over time.

The design engineers at Dromcons specialize in various types of projects, from large-scale national works to smaller bridges for private owners. Key stages in bridge design include:

• Geotechnical studies – analyzing the soil where the bridge foundation will be placed.
• Structural calculations – determining dimensions, materials, and required strength.
• Material selection – prestressed concrete, steel, or combinations, depending on the project.
• Execution details – plans and drawings that guide builders step by step.
• Permits and approvals – obtained by Dromcons to ensure compliance with all regulations.
  
  

Execution of Road Infrastructure Works

The Dromcons team doesn’t stop at the design stage. We are a road and bridge construction company, handling both design and execution.

What does building a road or bridge involve?

• Land preparation and earthworks – leveling and soil reinforcement.
• Road layers – foundation, ballast, asphalt.
• Construction of bridges and culverts – according to project plans.
• Drainage and stormwater systems – to prevent water accumulation.
• Road markings and signage – for traffic safety.
• Quality control – carried out in Dromcons’ own authorized laboratory, testing all materials used.

Case Studies: Road and Bridge Infrastructure Works

1) Road Design and Execution: Arad East Bypass

This project was completed in partnership with SC PORR Construct SRL, with beneficiaries being the Arad County Council and C.N.A.I.R through D.R.D.P Timișoara. It represented a major step in developing regional infrastructure. Dromcons provided design and technical assistance for an approximately 11 km road, 7 intersections, and various auxiliary works. Detailed topographic studies, all necessary permits, and a complex geotechnical study with 75 drillings at different depths were also carried out.

2) Bridge Design and Execution: DN14A Blăjel

This project, carried out with GEIGER Transilvania SRL, was an important milestone for improving local road infrastructure. The Dromcons team conducted a rigorous geotechnical study, including medium-depth drillings, shallow drillings, and heavy dynamic penetrations, to ensure the bridge’s stability and durability. Detailed topographic studies and complete design and technical assistance services guaranteed precise and efficient execution.
