EXAMPLES PILOT PROJECTS
WASTEWATER TREATMENT PLANT
PROJECT GOALS Design development and construction documentation production for the construction of the new wastewater treatment plan.
PROJECT CHALLENGES •
•
•
•
•
Many separate objects (buildings) on the large parcel. A lot of mechanical equipement. A lot of pipes with different sizes, mostly underground. Need for accurate elevations of the buildings and building elements. Engineering team with little or no experience with BIM (lead by experienced internal BIM Manager).
HOW DID WE APPLY BIM - Structural engineering team used Revit for the model creation and construction documentation development. - Navisworks was used for colision detection. - Internal BIM Manager was in charge of: -
accurate positioning of the each building in the comprehensive BIM model, coordination with mechanical team, coordination with external collaborators and other project stakeholders, template and construction documentation control, schedules and quantities, colision detection (coordination)

INDUSTRY HALL
PROJECT GOALS Reconstruction of the industry hall for manufacturing of food products – architectural and HVAC design.
PROJECT CHALLENGES • •
• • •
• • • •
Old project paper documentation (from 1970). Hall is in use with current food production – need for several project phases. Lot of existing mechanical equipement. Structure must stay intact. Need for good presentation of the project solution with goal to continue further project development. Constant changes during construction. Small HVAC team – short deadlines. Architectural team uses 2D CAD software. HVAC team uses BIM software.
HOW DID WE APPLY BIM - With site survey and with usage of the existing paper documentation, architectural As-built BIM model was created. - 2D CAD (dwg) drawings were produced directly from the BIM model (for Architectural team) - Architectural BIM model (rvt) was uses as a reference by HVAC engineers
HOW DID WE APPLY BIM - Existing mechanical equipement was modelled with bounding boxes placeholders (coarse geometry). - Structural components were modeled accurately. - New HVAC elements were modeled in available space.
HOW DID WE APPLY BIM Need for good presentation of the project solution with goal to continue further project development. - Renderings for the investor were prepared - Live presentation of 3D model with Architectural and HVAC models combined.
