Got land or planning to build? Discover why topographic surveys are the first mandatory step

Are you a real estate developer preparing to launch a large-scale project? Or maybe you’re a future homeowner eager to start building your dream house? No matter which side you’re on, one of the very first steps before any construction begins is the topographic survey.

These surveys define exactly where your land begins and ends, how it is shaped, what elevation differences exist, and what potential risks or challenges may arise. That’s why topographic measurements must be carried out precisely, by authorized specialists using modern equipment.

In this article, you’ll discover what topography in construction really means, why it is so important, and how the Dromcons team, with over 20 years of expertise, can support your project.

What Are Topographic Surveys and Why Are They Essential?

A topographic survey is a set of techniques used to collect essential data about your land—its shape, boundaries, elevation differences, and relationship with neighboring areas. This data is then translated into a topographic plan, a graphic representation of the terrain.

In other words, the surveyor “translates” the land into coordinates and technical drawings, which are crucial for designers, authorities, and builders.

Through topographic surveys, you’ll learn:

• the exact boundaries of your property;
• existing elevation differences;
• how your land relates to roads or neighboring properties;
• the correct placement for foundations and utilities.
  
  

The Importance of Topographic Surveys: Safety, Legality & Cost Control

Imagine you place a fence “by eye” without proper measurements. Later, during registration, you discover you’ve encroached 40 cm onto your neighbor’s land. That means extra costs, legal disputes, and wasted time.

If surveys are not performed correctly, issues can arise from several angles:

• Extra costs – mistakes in placement can lead to demolitions, utility relocations, or lawsuits.
• Legal requirements – without cadastral documentation and topographic plans, you won’t get a building permit.
• Safety – the most important aspect. A house built on uneven terrain or in the wrong position can face serious structural issues later.

Types of Topographic Surveys You Need

1. Topographic Surveys for Building Permits

Romanian law requires property owners to submit a topographic survey to obtain a construction permit. Authorities review these documents and approve the project only if it complies with zoning regulations.

2. Land Staking for Foundations and Utilities

Once you have the permit, the land must be staked. This means the surveyor marks exactly where the house, foundations, and utility routes will be. This ensures your builder knows precisely where to dig, without intersecting other networks.

3. Topographic Plans Approved by OCPI

The OCPI (County Office for Cadastre and Real Estate Publicity) and ANCPI (National Agency) validate topographic plans. These are mandatory for cadastral documentation or for registering land in the Land Book. For example, converting agricultural land into buildable land requires such a plan.

4. GPS Surveys for High Precision

Large-scale projects, like logistics halls, require extreme precision. GPS surveys provide centimeter-level accuracy across large areas—essential for industrial and infrastructure projects.

Advanced Topographic Surveys for Construction and Infrastructure

For complex projects, Dromcons offers advanced surveying services, including:

• Situation Plans (PAC) – reflecting real land conditions, required for design and approvals.
• Volume Calculations – estimating how much soil needs excavation or fill.
• PUG – PUZ – PUD support – full assistance for urban development plans.
• Staking – marking projects on the ground with millimetric accuracy.
• Orthophoto Plans – geometrically corrected aerial images, ideal for roads and residential developments.
• 3D Scanning – advanced solutions for complex terrains and structures.
• Lidar Measurements – highly detailed digital models, perfect for large infrastructure projects.
  
  

From Land to Final Plan – The Surveying Process

Here are the main steps:

1. Document review – property deeds, old maps, and project requirements are analyzed.
2. Field measurements – using total stations and GPS equipment to capture elevations and boundaries.
3. Data processing – specialized software converts data into precise digital plans.
4. Final documentation – the client receives approved plans for both authorities and the construction team.
   
   

Benefits for Homeowners and Companies

For Homeowners

• Cost savings – avoid expensive corrections later.
• Legal clarity – no disputes with neighbors or blocked permits.
• Safety – prevents structural risks for homes with basements or on uneven land.

For Companies

• Precision – engineers and builders rely on exact coordinates.
• Speed – no costly delays due to errors.
• Lower costs – avoids utility relocations or demolitions.

Real-World Case Studies from Dromcons

1) Arad East Bypass Road – 11 km of road, 7 intersections, and auxiliary works. Detailed topographic surveys and 75 geotechnical drillings ensured accuracy and safety.

2) Oradea Metropolitan Ring Road – 8 km road and 3 intersections. Extensive surveys and geotechnical studies guaranteed a durable and regulation-compliant result.
