BIM and the MacLeamy Effort Curve, Optimizing the Construction Process

profesional bim trabajando en modelo bim de estacion de metro

The construction industry has benefited greatly from the BIM methodology because it has changed the processes and also the way they are designed and built. One of the substantive changes is in the redefinition that BIM proposes regarding the stress curve throughout the construction process: the well-known MacLeamy Curve.

The MacLeamy Curve

The MacLeamy Curve illustrates the relationship between the effort invested in the design and construction phases of a project and the impact it has on its quality and cost. Traditionally, most of the effort was applied during the construction phase. However, the MacLeamy Curve proposes a paradigm shift: investing more effort in the early design stages can have a significant impact on reducing costs and errors during construction.

Intersection of BIM and MacLeamy Curve

The BIM methodology aligns perfectly with the MacLeamy Curve. BIM promotes early collaboration between teams that allows potential problems to be identified and resolved before they become costly fixes during construction. Early collaboration and information sharing result in greater efficiency and accuracy, translated into the effort curve proposed by MacLeamy.

Advantages of the BIM Methodology

  • Cost Reduction: Detecting conflicts and errors in the design phase avoids unforeseen expenses during construction.
  • Improves Quality: The precision and information that BIM provides leads to higher quality construction.
  • Time Optimization: Construction time is reduced thanks to the detailed planning required by BIM.
  • Sustainability: BIM software packages allow you to analyze the energy efficiency and sustainability of any project.

Types of Leveling in Surveying

servicio topografico de nivelacion geométrica

Leveling is an essential technique in topographyc surveying, as it allows for the precise determination of the relative height between specific points on a given plot of land. This practice is key in the planning and execution of engineering, construction, and cartographic projects, as it provides crucial information about the terrain’s relief. This, in turn, facilitates the design of structures that adapt to the site conditions and optimizes the calculation of necessary earthworks.

Additionally, understanding the slopes of the terrain is fundamental for the architectural development of a project. This knowledge enables the proper design of vital infrastructure, such as sanitary systems, which rely on a minimum slope to ensure the correct flow and evacuation of fluids. In areas with steep inclines, the topographic data obtained through leveling is indispensable for determining whether cut and fill operations are required or if stepped constructions will be used to take advantage of the natural topographic features.

Below, we will explore the different types of leveling used in surveying, each with its characteristics and applications:

Geometric Leveling

Also known as differential leveling, it is one of the most precise and commonly used methods in surveying. This method is based on the use of an optical or automatic level and a leveling rod to measure the difference in height between two points. It is carried out by establishing a horizontal line of sight and reading the elevations at different points.

It is commonly used for:

  • Civil engineering and construction projects
  • Road and railway construction
  • Installation of public utilities

Trigonometric Leveling

This method is based on the use of angles and distances measured with a theodolite. It involves measuring vertical and horizontal angles along with the distance between points of interest to calculate the height difference using trigonometric formulas. This method is especially useful in rugged terrains where geometric leveling can be difficult to implement.

This method is suitable for:

  • Mapping mountainous terrains
  • Geological and mining studies
  • Installation of telecommunications towers and power lines

Barometric Leveling

This method uses atmospheric pressure to determine the elevation of different points. It employs barometers or altimeters to measure air pressure at various locations and then calculates the height difference based on pressure variations. Although less precise than other methods, it is useful for preliminary surveys and in extensive areas where other methods would be impractical. It is commonly used in:

  • Geographic explorations
  • Environmental studies
  • Topographic surveys in remote areas

GPS Leveling

This method uses satellites to determine the elevation of specific points relative to sea level. It employs GPS receivers to capture signals from multiple satellites and calculate the height using complex algorithms. GPS leveling is increasingly popular due to its high precision and ability to cover large areas quickly.

It is optimal for:

  • Digital mapping
  • Topographic surveys in large infrastructure projects
  • Monitoring and managing natural resources

Hydrostatic Leveling

This method uses the principle of communicating vessels to determine height differences. It involves using a tube filled with liquid (usually water) that connects two points. The height of the liquid at both ends of the tube is measured to calculate the height difference between the points. It is a simple and effective technique for short distances and in areas where other methods are impractical. It is especially useful for indoor installations, leveling buildings and structures, and adjusting machinery and equipment, where the simplicity and economy of the method are significant advantages.

In conclusion, the choice of leveling method in surveying depends on several factors, including the required precision, terrain characteristics, the extent of the area to be covered, and available resources. Each method has its own advantages and applications, so it is essential to consult with specialists to determine the most appropriate method for each case.

Geodetic Control in Coastal Surveys

levantamiento topografico costero

Geodetic control in coastal surveys is an essential practice that ensures the accuracy and consistency of geographic and cartographic data. The densification of the control network and the verification of reference systems are fundamental processes to obtain reliable and precise information, which is crucial for safe navigation, project planning, and environmental studies in coastal areas.

Densification of the Geodetic Control Network

The densification of the geodetic control network is essential to provide a precise reference framework that allows for the exact positioning of points of interest in coastal surveys. This process includes adding more control points to an existing network, thereby improving the resolution and accuracy of the survey.

Horizontal Control

Horizontal control refers to the positioning of points in a two-dimensional plane, typically using geographic or UTM (Universal Transverse Mercator) coordinates. Various methods are used to densify this network:

  1. Traditional Methods: These include the use of total stations and theodolites to measure angles and distances between points. These instruments require a direct line of sight between points, which can be challenging in irregular coastal terrain.
  2. GNSS: GNSS systems, such as GPS, allow for highly accurate positioning of points. This method is especially useful in coastal areas where direct lines of sight are difficult to obtain. GNSS receivers placed at various control points provide data that can be processed to obtain precise coordinates.

Vertical Control

Vertical control focuses on the elevation of points relative to a reference datum, such as mean sea level. This control is crucial for studies requiring information on the elevations and depressions of the coastal terrain.

  1. Geometric Leveling: This technique involves using optical levels and rods to measure height differences between points. It is a very precise method but labor-intensive.
  2. GNSS Altimetry: Similar to horizontal control, GNSS systems are used to determine heights relative to a reference ellipsoid. However, corrections must be applied to obtain precise elevations relative to sea level.

Verification of Reference Systems

The consistency and accuracy of coastal surveys depend on the proper verification and use of reference systems. This includes ensuring that all control points and collected data refer to the same geodetic reference system.

  1. Consistent Reference System: It is fundamental that the reference system used for topographic survey coordinates, geodetic control, and navigation aids is the same. This avoids discrepancies in the information and ensures that the data are interoperable.
  2. Data Verification and Adjustment: Verification includes a thorough analysis of records and, when necessary, field review. Comparing the coordinates of physically obtained control points with provided coordinates helps identify and correct potential errors.
  3. Accuracy and Corrections: To meet standards such as those in the IHO’s (International Hydrographic Organization) publication S-44, it is crucial to ensure that the corrections between ellipsoid heights and sea level are accurate. This includes applying geoid models and correcting potential systematic errors in GNSS measurements.

Importance of Geodetic Control in Coastal Surveys

Geodetic control in coastal surveys not only provides an accurate basis for cartography and navigation but also is essential for various practical applications:

  • Navigation Safety: It helps mariners avoid coastal hazards by correctly locating details such as lighthouses and buoys.
  • Environmental Studies: It provides precise data for analyzing changes in the coastline, erosion, and other natural phenomena.
  • Planning and Construction: It is crucial for coastal infrastructure projects, such as port construction and coastal defenses.

topographic survey in the development of hydraulic works

Within infrastructure projects, a topographic survey is a fundamental study in the development and planning of hydraulic works, as it provides detailed and precise information about the terrain, allowing for efficient planning and execution of any water-related project.

Whether it’s the construction of dams or the installation of drainage systems, a topographic survey is essential at every stage of the process. In this article, we will explore the advantages of conducting a topographic survey in hydraulic works.

Enables Precise Planning

One of the significant benefits of topography in hydraulic works is the ability to carry out precise planning. The data collected during the survey provides detailed information about the area’s topography, terrain elevation, and the location of important features such as rivers, lakes, or reservoirs. This information helps us design and locate structures such as dams, channels, and drainage systems accurately.

Facilitates Optimization

With accurate data on the terrain’s topography, engineers can optimize the design of hydraulic works to ensure their effectiveness and durability. Thanks to Acero Estudio’s topography services, we can identify possible challenges or limitations of the terrain, such as steep slopes, erosion-prone areas, among other important details that can make a difference in risk mitigation.

Water Management

With global warming, water is becoming an increasingly important resource, so managing this liquid element is vital, and the discipline of topography assists us in this task by allowing proper management through information that enables us to use it with minimal environmental impact.

Reduction of Flood Risk

Understanding the geography and, above all, the topography of a terrain will help us develop constructive strategies that avoid flood-prone areas or, if the terrain is inherently flood-prone, help us identify potential watercourses to avoid them or create resilient structures for them.

What level of development is suitable for construction projects?

bim modeling service

The optimal Level of Development (LOD) for construction projects varies depending on the specific needs of each project and the stage it is in. In the Building Information Modeling (BIM) methodology, LOD refers to the level of detail and development of a digital model.

LOD provides a standardized structure that guides the creation and management of BIM models, allowing for a clear understanding of the information contained in the model at each stage of the project. By implementing LOD, we ensure the consistency and accuracy of the data, facilitating collaboration among different project stakeholders and improving decision-making efficiency.

Different Levels and Their Uses:

Generally, the different levels of LOD are used as follows:

  • LOD 100: Used in the early stages of the project, providing a conceptual representation of the design without specific details. It is useful for initial planning and project visualization.
  • LOD 200: Focuses on the general geometry of the project, including basic dimensions and spatial relationships. It is suitable for the schematic design phase, where the main project ideas are explored and refined.
  • LOD 300: Provides an accurate representation of individual project elements, with specific details such as exact sizes and shapes. It is useful during the detailed design phase and coordination among disciplines.
  • LOD 400: Includes detailed information about the manufacturing and assembly of project components, allowing for the generation of construction drawings and virtual construction simulation.
  • LOD 500: Represents the as-built information of the project, including precise installation and manufacturing details. It is useful for building management and maintenance once completed.

For residential construction projects, the most suitable BIM LOD is typically LOD 300 or higher, as a high level of detail is required for home design and construction.

In industrial construction projects, such as factories or production plants, LOD 400 is commonly used due to the need for detailed information about industrial systems and equipment.

For infrastructure construction projects, such as roads or bridges, LOD 300 may be sufficient in the design stages, but LOD 400 may be necessary for precise planning and construction of structural elements.

In commercial construction projects, which may include office buildings, shopping centers, or hotels, LOD 400 is widely used to ensure accuracy in planning and execution.
