What does "engineering judgment" refer to in code calculations?

"Engineering judgment" refers specifically to the application of an engineer's experience and expertise to make informed decisions that may not be strictly defined within the provisions of building codes. This judgment allows engineers to apply practical knowledge to unique situations where code guidelines may not cover every scenario or when a code may be too prescriptive.

Using engineering judgment is crucial in cases where innovative approaches or materials are utilized, ensuring that safety, functionality, and efficiency remain prioritized, while still adhering to professional standards. It recognizes that codes provide a baseline for safety but that real-world applications often require thoughtful consideration and the ability to extrapolate from established practices.

In contrast, the other options focus on other aspects of engineering and construction practices. The selection of materials for efficiency often involves straightforward criteria provided by codes and standards. Compliance checks by building inspectors are procedural and verify adherence to codes but do not involve expert decision-making. Estimating project costs is typically a financial assessment rather than a technical evaluation of engineering solutions. Therefore, the correct understanding of "engineering judgment" lies in the nuanced application of expertise in complex situations that codes may not explicitly address.
