Until now, the restoration of buildings and architectural structures was largely limited to cleaning and decorative restoration due to the inability to obtain detailed insights into these constructions. Today, thanks to advanced tools like the 3D laser scanner, we can delve deeper and identify elements that allow us to thoroughly understand these structures.

It is undeniable that the 3D laser scanner is transforming how we study and understand historical buildings. This groundbreaking technology provides an accurate representation of the shape and dimensions of infrastructure, traces of walls or sections from different periods, and even subtle deformations that are not visible to the naked eye but are clearly detected by the scanner.

With this wealth of information, historians, architects, and other cultural heritage professionals are achieving the unthinkable: first, creating precise models of this knowledge for future generations, and second, carrying out appropriate maintenance actions based on the state of these structures, preventing irreparable damage.

What Level of Precision Does the 3D Scanner Provide?

Accurate Record of the Current State

The 3D scanner’s point cloud is highly precise, capturing everything from cracks to textures with remarkable fidelity and storing this data digitally. This ensures that the information will be available for future generations.

Restoration Programs

The 3D model, combined with BIM modeling tools, allows the creation of restoration programs, maintenance projections, and the evaluation of interventions before implementing them on-site, reducing risks significantly.

Access to Collective Knowledge

Thanks to the 3D scanner, ancient buildings can be transformed into information that benefits and transcends the current generation. This technology not only benefits the community that houses these structures but also the entire world. In the future, people may even “visit” historic buildings virtually, thanks to the integration of this technology with virtual reality.

Protection from Human Risk

In many parts of the world, historical structures have been closed to protect them from excessive tourist activity or environmental damage. The 3D laser scanner enables us to gain a deeper understanding of these areas without the risks associated with walking through or visiting unstable buildings that may collapse.

What Errors Occur in Topography and How to Avoid Them?

conoce los errores en la topografia

Topography, like any discipline, demands expertise and knowledge to avoid errors and achieve optimal results. In our field, accuracy is critical, as even minor errors can accumulate and lead to significant negative consequences in engineering projects if not detected in time.

The main types of errors in topography are systematic errors and accidental errors. Let’s understand how they arise and how to prevent them to ensure the quality of the results.

Systematic Errors

These are deviations that occur due to equipment malfunctions, incorrect calibrations, improper procedures, or environmental factors. Systematic errors tend to repeat under the same conditions and, if not corrected, can lead to consistently inaccurate results.

Examples of systematic errors:

  • Uncalibrated total stations, damaged leveling instruments, etc.
  • Environmental factors such as light, metal expansion due to heat, or fog affecting instrument readings.

Accidental Errors

These are deviations caused by unpredictable variables such as human error or accidental instrument movements. While they are unavoidable to some extent, these errors are typically minor when proper procedures are followed.

Examples of accidental errors in topography:

  • Instrument reading errors due to operator distraction or carelessness.
  • Vibrations in the terrain caused by machinery or other external factors.

How Do We Prevent These Errors?

As a specialized topography company, we implement procedures to minimize errors and ensure the reliability of our work. Below are the measures we take:

To Prevent Systematic Errors:

  • Regular maintenance of equipment: We have preventive maintenance plans to ensure all instruments function perfectly.
  • Calibration and verification: Total stations and levels are calibrated and checked before any project.
  • Evaluation of atmospheric corrections: Adjustments are made for environmental factors, such as material expansion on hot days.
  • Deviation tests: These tests are conducted to identify potential systematic errors.

To Prevent Accidental Errors:

  • Continuous training: We provide regular training and updates to our personnel.
  • Advanced technology: Our tools feature integrated viewers and systems to reduce common errors.
  • Comparative measurements: We conduct multiple measurements to identify and eliminate inconsistencies.

The Gauss Curve and Its Application in Topography

The distribution curve, or Gauss curve, helps identify potential errors by analyzing deviations in the data. It allows us to distinguish between systematic and accidental errors effectively.

This statistical tool enables informed decisions about the quality of the collected data and the implementation of corrections when necessary.

Setting Out in Topography: Key to Error-Free Construction

ingeniero topografo

Once a topographic survey has been conducted, companies gain precise information about the land where construction will take place. A topographic setting-out is the process of validating the data from the prior survey to initiate the construction process.

Why is setting-out important?

A setting-out ensures that the structure is correctly positioned, avoiding errors that could lead to additional costs and project delays. While there are usually ways to validate information from a topographic survey, setting-out minimizes the risk of any erroneous values persisting.

How do we carry out our setting-out process?

  1. Preparation: We analyze the technical design and determine the key points to be marked on the site.
  2. Positioning: Reference points are established using tools like total stations, optical levels, or GPS.
  3. Marking: Stakes, lines, and other marks are placed to serve as guides for construction teams.

Applications

  • Construction of buildings, roads, and bridges.
  • Industrial facilities and plants.
  • Urban development projects and public utility networks.

What Types of Clashes Does the BIM Methodology Prevent in Construction Projects?

que colisiones evita bim

As we have illustrated on several occasions, the BIM methodology is essential in preventing conflicts in construction projects. These conflicts are often referred to as clashes, as they involve collisions or inconsistencies that, thanks to BIM, can be avoided due to the logic embedded in its software.

Physical Clashes

These occur when two or more elements of a project occupy the same physical space. In traditional construction, design tools are not updated in real time or are often not incorporated into the main plans, leading to issues during execution.

These are serious problems that can affect structures, such as:

  • A pipe running through a structural beam
  • Water or ventilation ducts colliding with electrical installations
  • Mechanical equipment lacking sufficient space for maintenance or installation

BIM identifies these interferences through “clash detection” analysis, allowing for appropriate corrections in the model before the issue results in a poorly executed construction.

Functional Clashes

These involve incompatibilities in the performance or operation of systems, including electrical, plumbing, and HVAC systems. Examples of functional clashes include:

  • Inadequate ventilation in a space due to poor placement of HVAC systems
  • Electrical systems designed for loads higher or lower than required
  • Hydraulic connections incompatible with equipment specifications

Design Issues

These relate to aesthetics, accessibility, or regulatory compliance. In every construction project, installations must adhere to regulations and good design practices that ensure proper ventilation, lighting, and pedestrian circulation.

By using pre-developed BIM models, we ensure compliance with all parameters of the original design and can identify the proper placement of installations in time to achieve an optimal building design.

Planning and Scheduling Errors

Thanks to 4D simulation tools, BIM incorporates the dimension of time, helping to avoid scheduling problems such as:

  • Equipment installation being scheduled before the space is built
  • Overlapping activities that cause delays or additional costs

As you can see, the benefits of BIM in construction enable effective project management, planning, and execution with accurate and up-to-date information.

The BIM Methodology: Understanding Its Application in All Phases of a Project

fases de BIM para los proyectos de construccion

If you’re on this page, you might be wondering whether implementing the BIM (Building Information Modeling) methodology in your projects is truly relevant or if it’s just a trend that will soon be replaced by another workflow system.

Let us assure you that BIM is here to stay. In the construction and architecture industries, it has become an essential tool for large-scale and complex projects because it facilitates work throughout the entire lifecycle of a project—from design and construction to delivery and building maintenance.

If you think BIM is unnecessary, consider that many countries, including the United Kingdom, Denmark, Finland, Sweden, Norway, Australia, and Singapore, already mandate BIM for state construction projects. In this brief article, we will show you how BIM methodology is applied in each phase of a project.

PROJECT PLANNING AND DESIGN

This is the initial stage of a construction project, where BIM modeling begins. It allows the creation of preliminary sketches of 3D models that link geometry with site characteristics. At this stage, critical information about structural materials and costs is also defined. The benefits of BIM during this phase include:

  • Enabling visualization of the project.
  • Enhancing coordination among professionals.
  • Improving the accuracy of cost calculations for procurement.

For example, in an architectural project, BIM can simulate the behavior of natural lighting in a building or estimate energy consumption, optimizing the design from its conception.

PRE-CONSTRUCTION

In this phase, the BIM model evolves, becoming more detailed and incorporating schedules, costs, and resource allocation for the project. As the project progresses, the level of detail in the 3D model increases with higher Levels of Development (LOD).

Key benefits include:

  • Task definition using 4D models (time and space).
  • Improved planning for subcontractor work.
  • Reduced risks of cost overruns and delays.

CONSTRUCTION PHASE

During the construction process, BIM software serves as a centralized and up-to-date information hub, keeping all teams informed about changes, delays, or incidents that may arise. Early warnings minimize issues, significantly reduce errors, and prevent rework. BIM’s benefits during this phase include:

  • Centralized monitoring of progress and schedules.
  • Resource and materials management.
  • Quality control.

Cloud repositories also enable technical teams to access information about specific parts of the project anytime, anywhere.

MAINTENANCE AND OPERATION OF THE BUILDING

The utility of a BIM model doesn’t end with construction. With the help of various software packages and extensions, BIM allows for projections of maintenance for critical areas, making it a vital tool for managing the constructed asset.

  • Tracks critical components requiring maintenance.
  • Updates the model as needed.
  • Enables operational efficiency analysis.
