What is the primary purpose of integrating models in coordinating mechanical, electrical, and plumbing systems during CDs?

• A. Feasible installation, conflict resolution, and coordinated space planning
• B. Increased rework and delays
• C. Isolated subsystem development
• D. Minimal documentation

Answer: (A)

When coordinating mechanical, electrical, and plumbing systems during construction documents, the aim is to create a coordinated, buildable design where installations fit within the given spaces without surprises. An integrated model enables clash detection and resolution early, so components don’t physically collide or require awkward routing. It also supports coordinated space planning, ensuring equipment, ducts, and conduits have accessible paths and fit within room dimensions and ceiling heights, while aligning with architectural and structural elements.

This approach reduces field changes and rework by exposing conflicts before construction starts and by validating that systems can actually be installed as designed. It also provides a single source of truth for documentation, helping trades and installers follow the intended sequence and coordination.

Choosing options that emphasize more rework, isolated subsystem development, or minimal documentation would undermine these benefits. Integrating models specifically addresses constructability, coordination, and installability, which is why it’s the best answer.
