    Management Summary

    The use case describes the integration of complex technical systems - in this case special laboratory systems - into the BIM process.  

    A clear and unambiguous interface description and delimitation of the technical/laboratory facilities to the building services engineering is to be mapped, combined with all essential information for the integral cooperation of all project participants in the entire planning process
    and life cycle of a building.

    The main components of the use case are:

    • Development of TecBox as a simplified representation of complex technical systems including their connection points to the MEP.
    • Creation of unambiguous interface definitions with corresponding parameterization / attribution with the aim of an open exchange of technical models in accordance with the Open BIM concept.
    • Loss-free further processing of information independent of the software solutions used
    • Representation of the TecBox workflow in the BIM process

    Purpose and Scope

    • Higher efficiency of the evaluation and evaluation of transfer / interfaces.
    • Clear assignment of services with model-based transfer / interfaces.
    • Transfer of TecBox planning data to MEP trades.
    • Transfer of the updated planning data in the planning process.
    • Optimization through automation.

    Description

    The PG IFC4Lab - the result of a joint initiative of EGNATON e.V. and buildingSMART Deutschland e.V. (aka buildingSMART German Chapter) - has set itself the task of a standardized transfer of information for data exchange in the BIM process of the specialist area of laboratory planning, laboratory equipment and laboratory operation.
    All relevant and required data and information in the entire planning and operating process are to be considered with the aim of providing sustainable solutions for both the technical trades and the information management in the BIM process.

    The standardization of this information 
    is one of the greatest challenges.

    The definition of "laboratory equipment or technical equipment" includes a large number of equipment systems (laboratory benchtops, laboratory sink units, fume hoods, fume hood cabins, extraction elements, media supply modules) 
    with special design requirements and material properties, which are suitable for use in a wide variety of laboratories and production plants.

    For a clear but also simplified representation of these complex interrelated technical systems in the overall project, the concept of the TecBox was developed.

    The TecBox should contain the outer geometric shapes of the respective contiguous system as well as other data such as weight information and map their connection points to the MEP including MSR.

    The semantic definition of the TecBox in the BIM model is the representation of a predefined, non-hierarchical and non-overlapping zone within a room or building complex with a predetermined use, function and shape.
    It depends on the definition of the technical/laboratory facility as well as resulting transfer interfaces.
     
    It is used for collision planning and for deriving relevant information for architects, planners and operators.

    The BIM module "TecBoxContent" was developed for the capture and representation of the specific modular laboratory technical equipment (content of the TecBox).

    Further independent equipment, which among other things contribute to the design and specification of the TecBox, is to be captured and represented in the BIM model as EquipmentBox.

    Both "BIM" building blocks - TecBoxContent and EquipmentBox - are not explained in detail in this UseCase and are considered separately.

    TecBox - Data specification

    Data of the TecBox:

    TecBox - number

    with additional inheritance of the building structure: floor / room number / room name

    • Geometry (X, Y, Z) = 0,0,0
    • Dimensions (X, Y, Z) = 3600/900/280
    • Weight = 850

     

    Transfer points / Interfaces:

    • Transfer point for gaseous media
    • Transfer point for gaseous disposal media (e.g. He recirculation - via attribution)
    • Transfer point for liquid media
    • Transfer point for liquid disposal media
    • Transfer point for high power current
    • Transfer point for low power current
    • Transfer point for MSR
    • Transfer point for ventilation

     

    TecBox - number = building / floor / room / position.

    • Geometry (X,Y,Z) = 0,0,0
    • Dimensions (X,Y,Z) = 3600/900/2800
    • Weight = 850

    BIM Objectives & Benefits

    The information of the transfer points is important for individual TecBox(es) on the one hand and for the overall technical supply representation of a building complex on the other hand.

    By displaying the transfer points/interfaces with the integrated performance parameters, the building services trades should be able to determine the overall dimension of the respective building services system (water, wastewater, ventilation systems, etc.) with the corresponding further software systems and to precisely locate the individual media transfer points at an early stage.

    In case of performance adjustments of the supply engineering in the planning and operator process, the defined transfer/interfaces can be read out accordingly and evaluated accordingly.

    Interaction with the specialist planners makes it possible to continuously update the data and information of the TecBox(es) in the planning process and to ensure fast and precise transfer to other calculation software systems by means of data-based transfer.

    Control systems can be integrated to detect and display changes at the transfer/interfaces. This enables the specialist planners to react to changes at an early stage, to adapt the planning accordingly and to save time and costs.

    Delimitation

    • Geometric elements for transfer points of the MEP shut-off devices with defined specification of the performance parameters
    • Geometric elements for transfer points of the electrical supply lines with specification of the performance parameters
    • Geometric elements for transfer points of the MSR supply lines with specification of the performance parameters

    Important Note: The main Object that might be applicable for TecBox could be ifcSpatialZone. For that reason an additional Predefined Type is really needed.

    Overall process

    Description

    At the beginning of the planning process, the requirements specified by the customer for the equipment/laboratory and factory equipment as well as instrumentation are translated by the specialist planning department into the specific trade language using various methods.

    By means of TecBoxes, which represent a summarized unit of an equipment/laboratory complex within a laboratory or building complex, this information is summarized in a structured but still simplified form and provided with information such as weight, requirements for special structural or building environment qualities as well as technical supply connection parameters.

    The technical installations within the TecBox (parallel process - TecBoxContent) form the basis for the design of the TecBox.

    By means of transfer of the specialized model of the laboratory technical plant with TecBox methodology, the laboratory and building planning can be realized with complex elements in a short time.

    In verification iterations, the results and requirements are systematically integrated into the planning documents by the participants and refined in feedback loops up to the freeze of the planning sections - see process map - sub-process: TecBox definitions.

    In particular, the TecBox serves as the core of the interface and requirements definition.
