BIM use cases for Swiss projects

Prepare concrete and reinforced concrete works from the structural model for tendering.

Capture flooring information per space in the space model as the tender basis - without a modelled floor build-up.

Print a room QR with room name and number and place it in every room - for orientation, logistics, and defect management during fit-out.

Prepare reinforcement and edge strips from the formwork and reinforcement model for construction execution.

Plan fastenings and suspensions from the model according to the contractor's requirements.

Provide precast concrete parts from the structural model for ordering and delivery planning.

Provide the modelled floor build-up with covering and subfloor for execution and quantity take-off.

Evaluate competition entries on a comparable basis - independent of each author's modelling style and software.

Extract quantities early in design and iterate cost alongside the model.

Prepare building simulation without manually rebuilding the architecture model for simulation tools.

Model gross volumes per storey and extract quantities for the urban design mass study.

Survey terrain and position reference on the existing site as the basis for demolition/new build or conversion strategies.

Survey and model the existing building shell as the basis for strip-back, extension, or change of use.

Survey and model existing building services for change of use or targeted replacement.

Interior finishes - maintain suspended ceilings in the model, from early room assignment through execution-grade layer modelling for MEP coordination.

Maintain the building envelope in the model - from early multi-layer construction through execution-grade facade layers for quantity take-off and building...

Coordinate drainage and wastewater early in the model - before clashes in risers and below ceilings trigger costly design changes.

Deliver space and door lists plus FM-relevant building services as structured data at handover to the operator - without full 3D plant modelling.

Maintain the spatial layout early in the model and decide on options - spaces only, optionally symbolic doors.

Derive door planning foundations from the model - dimensions, door type, and opening direction for door schedules and coordination.

Agree with the operator which objects they actually manage - and hand over only those with the agreed master data in the 3D model.

Model parking spaces as dedicated spaces from building design onward and evaluate count and areas directly from the model.

Model storey volumes and air spaces and derive floor area from storey volume minus air space.

Carry component quantities and materials in the model so a full LCA is possible without parallel quantity lists.

Hold usage-agreement requirements (SIA 260) per space in the model and derive readable visualizations from them.

SIA 416 area verification from the space model - area class via Reference, use via LongName.

SIA D0165 area verification from the space model - area class via Reference, use via LongName.

Maintain and update signage room numbers in operation - separate from the technical planning room number.

Which areas are coordinated in which coordination meeting - instead of everything against everything.

Align concept and feasibility early in the model - comparable to a sketch design, without execution detail.

Coordinate building services from construction project phase with IFC entities and PredefinedType - no longer schematic only.

Verify the exclusion zone model and structural sketch in the federated model - before planning runs into restricted zones.

Coordinate architecture and MEP in later phases and carry openings and recesses bindingly in the structural model.

Align load-bearing components between architecture and structural models - as previously done on 2D concrete pouring plans, now in the model.

Sketch special rooms quickly and roughly in the model and align them with users - no formal modelling guidelines, for meetings and visualization.

Like detail references in 2D sections, the detail reference overview shows in 3D where each standard detail applies - to spot planning gaps quickly and...

Establish a shared, georeferenced model reference from the start - most coordination mistakes happen because models are not aligned; fixing later is...

Maintain fire resistance classes in the architecture model from the end of the building project phase and check them against the fire protection concept.

Maintain sound reduction values Rw in the architecture model from the end of the building project phase and check them against acoustic planning.

Maintain clear installation access paths in the model and prove them clash-free - before large equipment or components can no longer be brought in.

Maintain clear maintenance spaces in the model and prove them clash-free - before plant becomes unmaintainable.

Carry the usable space of facing shells in the model and prove floor-area impact - before wet rooms become too small.

Design review at the end of each project phase - check planning quality and maturity, record open points, and document release for the next phase.
