What is a good reason to get the facilities engineers involved early in the planning of a new building design or major renovation?

Involving facilities engineers early in planning ensures that the design optimizes operations and

maintenance (C).

Early involvement allows engineers to recommend design choices that enhance energy efficiency,

system reliability, and cost-effective maintenance.

As-built drawings (B) are important but do not influence initial design decisions.

Operational benchmarks (A) can be developed later once the building is in use.

Punch list items (D) are addressed during final construction stages, not in the initial planning.
