Introduction: The LM.BIM 2025 service profile

The LM.BIM 2025 service profile is a central tool for the implementation of modern construction projects in the Austrian construction and real estate industry. It defines the BIM-related services for building construction, civil engineering and infrastructure construction and supplements existing service profiles such as HOA, HO-PS, RVS and LM.VM. With clear specifications on qualifications and responsibilities, it provides a reliable basis for the implementation of Building Information Modeling (BIM) in all project phases.

Particular attention is paid to the preparation of structured digital data for operation and maintenance. While these phases are not described in detail, LM.BIM 2025 defines requirements for how data from BIM projects can be prepared in such a way that it can be optimally used for subsequent operation and maintenance.

The use of LM.BIM 2025 is recommended in combination with the AIA (client information requirements) and BAP (BIM execution plan) standards from buildingSMART Austria, which provide an essential basis for the detailed definition of services. In addition, all defined services of the LM.BIM 2025 service profile are in the context of the detailed process description of openBIM projects in Chapter 4 of BIMcert Handbook 2024.

Innovations and further developments

The LM.BIM 2025 service profile builds on the experience of LM.BIM 2022 and contains numerous innovations:

• Integration of building construction, civil engineering and infrastructure construction:
  The BIM-related services have been comprehensively revised and adapted to the specific requirements of civil engineering and infrastructure construction. This further development was made possible by close cooperation with ASFiNAG, ÖBB and their BIM consultants.
• Introduction of the LM.BIM CODE:
  A standardized code was developed that clearly declares the basic services and optional services across all project phases and ensures a clear definition of service components.
  more details here.
• Revised allocation of services:
  Basic services and optional services were evaluated on the basis of practical experience and their interaction optimized. These adjustments were made possible through collaboration with BIG, FWAG and their BIM consultants.

Life cycle orientation

LM.BIM 2025 pursues a holistic approach that encompasses all phases of a construction project – from project initiation to planning, awarding, construction and handover through to data preparation for operation and maintenance. The aim is to optimize efficiency and cost-effectiveness over the entire service life of a building.

Variants of the client-side BIM lines

LM.BIM 2025 distinguishes between two central models for BIM management on the client side:

• BPL + BPS variant:
  The tasks of BIM project management (BPL) and BIM project steering (BPS) are assigned as separate roles. The BPL assumes the strategic management and control of the BIM processes, while the BPS coordinates the operational implementation as a supporting unit.
• BIM-M variant:
  In this variant, the roles of BPL and BPS are bundled in a joint unit, BIM Management (BIM-M). This integrative solution simplifies the coordination processes and provides a central point of contact for all BIM matters.

Variants of construction implementation as part of the BIM strategy

LM.BIM 2025 offers different approaches for BIM-based construction execution that can be flexibly adapted to the requirements of a project:

• Variant: BIM implementation by the planning team
  In this variant, responsibility for the BIM models remains with the planning team, which creates, updates and maintains the models during planning and construction. The construction site is connected to BIM by Site Supervision (ÖBA).
• Variant: BIM implementation by the contractors
  In this variant, responsibility for the BIM models during construction is handed over to the contractors. They take over the maintenance and further development of the models during the construction phase. This approach requires clear handover points and a precise definition of the requirements for model consistency. However, it currently has a major impact on the bidder field, as not all contractors have the necessary BIM skills. This can limit the selection of suitable bidders.

Structure of the services

The LM.BIM 2025 service profile divides the services into basic services and optional services. These are defined as follows:

• Basic services include the basic services required to implement an openBIM project in accordance with the BIMcert manual.
• Optional services depend on the project and are based on the use cases in accordance with the AIA. These services can be supplemented on a project-specific modular basis, whereby the effects on other organizational units and project phases must be taken into account.

In addition, basic services and optional services can be organized hierarchically into main items and sub-items. These are used as follows:

• Main items thematically encompass the sub-items they contain and serve as a thematic bracket. In resource and resource planning, they can carry the sum of all required expenses of the respective sub-items. The following applies: As soon as the respective sub-items are only partially planned, it is advisable to declare their expenses individually in resource and resource planning.
• Sub-items are detailed descriptions of required activities in the context of a superordinate main item. Sub-items serve to clarify required detailed activities within a main item, the provision of which in this form is relevant for the success of the project implementation.

LM.BIM Code

The LM.BIM Code serves as a standardized system for describing and structuring services in the implementation of BIM project management. It promotes clear communication, efficient collaboration and comprehensible documentation. Each code clearly refers to a specific service and enables the targeted assignment of tasks and responsibilities.

The LM.BIM 2025 service profile offers a clear, practical basis for the efficient implementation of modern construction projects in building construction, civil engineering and infrastructure construction. With flexible variants and precise specifications, it creates the conditions for effectively integrating BIM processes into project management and optimizing the data basis for operation and maintenance.
