Building Information Modeling

BIM sets new standards for civil engineering

BIM expertise

The BIM process sets new standards in the design and management process of buildings and is increasingly used in civil engineering (e.g., model-based quantity determination and cost planning).

TRIGIS is specialized in creating 3D models based on new and existing building projects.

This 3D model forms the basis for further planning, for administration and the subsequent managing of real estate and asset management.

This ensures efficient planning and optimization, as the digital construction model provides a realistic method of evaluation for various scenarios such as geometry, costs and timings.

Your advantages

  • Standard-based data storage (IFC standard)
  • All project partners have access to the same, up-to-date building data
  • Simultaneous data processing using cloud-based method of operation
  • High efficiency and quality in matters of design, building construction and facility management

Services

  • Process planning and advising on CAFM and BIM
  • Creation of documentation guidelines
  • Creation of requirement specifications for inventory documentation suitable for BIM
  • Building documentation
  • Data migration, maintenance and updating

BIM for public works

Finland and Norway were the first nations to set standards, followed by the national procurement directives of the European Commission, the UK and the Netherlands. Recently, joint public-industry initiatives were also established in France, Spain and Germany. 

In Germany, the Federal Ministry of Transport and Digital Infrastructure (BMVI) presented a national BIM road map, which essentially intends to implement BIM technology in public construction works by 2020.

BIM and surveying

Building information modeling (BIM) is the modern method of operation in matters of design, construction and management of buildings. BIM is based on the active interconnection of all stakeholders across the entire life cycle of a building.

TRIGIS supports these processes with many years of experience (more than 3 million m² of gross floor area surveyed) in building imaging and modeling.

Services

  • Organized BIM management
  • High-quality virtual building models
  • Professional inventory data collection
  • BIM checks during the building phase
  • TGA analysis and collision analysis
From reality via the point cloud to the model (here, Plant 3D)

BIM of existing buildings

For Building Information Modeling (BIM) of an existing building, the TRIGIS BIM team generates a 3D model of the existing building, including technical equipment. This is carried out in close cooperation with the BIM planner to determine the degree and density of detail.

Services

  • Imaging of existing building and its TGA (for instance, using 3D laser scanning)
  • Documentation of as-is state for purposes of planning, renovation and analysis
  • Creation of a base for future documentation
  • Building Information Modeling and 3D design
  • Images for marketing purposes etc.

BIM check during construction

TRIGIS examines BIM planning during the construction process. Using building survey methods such as tachymetry, 3D laser scanning or photogrammetry, nominal-actual comparisons are carried out and deviations are documented. This is proven to result in fewer errors and deviations during the building process.

Services

  • Nominal-actual comparisons during the building process
  • Checking point cloud against BIM/CAD
  • Accurate as-built documentation
  • Change management in the model

BIM in civil engineering

The BIM concept is slowly but surely reaching the field of civil engineering. In the next few years, significant developments are expected.

To use the advantages of BIM in civil engineering projects as well, TRIGIS has developed processes to accompany this development. Model-based quantity determination helps support the calculation, and contributes to work preparation, construction invoicing and as-built documentation.

In line with client wishes, TRIGIS pre-prepares 3D models of components, digital terrain models and 3D machine controls, and physically merges this data.

To avoid duplicate work steps, TRIGIS uses a recorded model as a base for a multitude of evaluations and displays.

For every construction phase, all construction participants may access current and accurate data.

Services

  • Accurate and rapid volume determination using 3D model
  • Change management in the model
  • Model representation of installation parts
  • Accurate as-built documentation

BIM software

Our experts already use the client’s information system. This avoids inconsistencies and interfacing problems. TRIGIS will also use your team’s software to generate a 3D model.

You will receive *.rvt, *.dwg and *.pln files with the exact level of detail required for the project.

Do you use Allplan, Vectorworks or other software with an IFC interface?

In that case, you will receive the BIM in ifc format.

TRIGIS Software

  • Autodesk Revit Architecture
  • Autodesk Revit MEP
  • AutoCAD Architecture
  • AutoCAD Plant 3D
  • AutoCAD Civil 3D

BIM detail levels

The level of detail defines the required amount of information in the virtual building models. It is also known as the completion level, level of definition or level of development (LOD). LOD depends on the respective model requirements and can be customized in line with client needs.

Our experts are happy to offer their advice.

Services

  • LOD 100: 3D volume model
  • LOD 200: Modeling of building components (walls, ceilings, stairs, etc.)
  • LOD 300: Representation with exact measurements, materials and positioning
  • LOD 400: Like LOD 300, but enhanced with exact product data
  • LOD 500: As-built model
LOD 200
LOD 300
LOD 400
LOD 500

Following the BIM process!

Helping to shape the BIM process instead of simply participating!

To fulfill this goal, our experts are involved in the Central German BIM network, among other things.

This initiative supports all participants who want to actively influence and shape the BIM market.

The Central German BIM network is independent of software, industry and job description.

Initiatives

  • Cooperating on creating standardized operating procedures
  • Certifications to document BIM expertise
  • Networking and information exchange
