BIM training models

One of the major projects of this reform initiative is the nationwide introduction of Building Information Modelling (BIM) for federal buildings. The "Efficient Construction in the Federal Government" reform initiative is gradually laying the digital foundations for optimising the entire construction value chain. One of the major projects of this reform initiative is the comprehensive introduction of Building Information Modelling (BIM) for federal buildings. The aim is to use a common digital model-based database to track project preparation, construction planning and execution, and later also building operation, in a multi-stage process (BIM master plan for federal buildings). Inros Lackner supports this process with extensive BIM experience. The digitalisation of planning processes is a key focus for the company. The mandatory use of BIM for federal infrastructure projects was supported from the outset and BIM structures were also established in the other specialist areas, which are increasingly being expanded. In 2023, BIM is also to be used on a mandatory basis for federal buildings to improve collaboration and increase cost and schedule reliability.

Support for user training
Based on the "BIM Masterplan for Federal Buildings", the BIM methodology is being introduced with a multi-stage strategy. This includes user training for employees of the federal building authorities. As a practice partner of ARGE Triple B, Inros Lackner was responsible for developing a training model. The aim of the training is to teach the participants model-based and collaborative working with software-neutral data exchange and the use of BIM in the construction process.

Structure of the training model
The basis for the model is a 3-storey office building with a non-rectangular floor plan without a basement. The interdisciplinary coordination model is made up of the property planning models (Revit, Allplan, ArchiCAD), the structural planning models (Allplan) and the building services models for heating, ventilation and sanitation (all Plancal Nova) and for electrical (DDScad).

Simplification and level of detail
To optimise the success of the training, the model was simplified in comparison to the actual planning. In this step, the technical installations were concentrated on a section of the floor plan. The load-bearing components of the property planning models were created identically to each other and to the components of the structural design model. The level of detail was increased from LOD 100 to LOD 500 in five consecutive, uniform office spaces. This makes it possible to virtually walk through the rooms and experience the differences between the development levels based on the geometric representation and the stored attributes. The components have been assigned exemplary information on material properties, assembly sequence, assembly times (e.g. in m³/h), production status, costs and acceptance status.

This makes it possible to demonstrate the interrelationships in terms of scheduling, construction progress control, quality inspection and acceptance and defect management. Plans could be derived from individual components. In a separate scenario, collisions were deliberately created for training purposes in order to recognise them as part of an automated inspection. Communication and documentation during the creation of the models was carried out using an issue-based Common Data Environment (CDE) with direct links to the respective authoring programmes.

• Initiating change together

  The integration of BIM can increase the long-term efficiency and quality of projects if compatible software and technologies as well as uniform data standards are implemented. This is the only way that the various pieces of information on planning, material utilisation and execution can be used consistently. This requires extensive knowledge and qualified specialists.
