Precise openings. Transparent approvals. A seamless digital process.
Slot and opening planning is a critical, yet often conflict-prone part of execution planning. Unclear responsibilities, manual coordination, and limited transparency create unnecessary risks and delays. With big®, the process becomes fully model-based: openings are clearly identified, reviewed, annotated, and approved directly in the model — fully traceable and transparent for everyone involved.
Challenge in conventional planning
In traditional projects, roles, workflows, and communication paths are often unclear: Who creates the opening plans? Who reviews first? How is approval documented? This lack of structure leads to errors and inefficiencies. With big®, all stakeholders work from a single, shared information source — without manual lists, parallel plans, or media breaks. Verified openings feed directly into discipline models and derived plans, making the workflow transparent, reliable, and highly coordinated.
The model-based SOD (slot and opening) process with big®
The model-based SOD process with big® consolidates all relevant models and enables precise identification of every opening through well-defined attributes and a consistent ID structure. Reviews happen directly in the model: statuses, comments, and changes are documented on the object, approval status is automatically determined, and all information is centrally evaluated. Model comparisons, structured lists, and seamless tracking ensure maximum transparency and traceability, making collaboration between MEP, architecture, and structural engineering more efficient and reliable.
With big®, slot and opening planning evolves from an error-prone coordination process into a structured, model-based workflow that connects all stakeholders transparently. The outcome: reduced risks, higher planning quality, and a reliable foundation for smooth on-site execution.
