What information is typically NOT included in as-built drawings?
Correct Answer
C) Original design calculations
As-built drawings document the actual constructed conditions, including field changes, final locations, and dimensions. Original design calculations remain with the design documents and are not part of as-built drawings.
Why This Is the Correct Answer
As-built drawings are record drawings that document the actual constructed conditions of a project, showing what was actually built rather than what was originally designed. Original design calculations are engineering computations used during the design phase to determine structural requirements, load capacities, and material specifications. These calculations remain part of the design documentation and are not transferred to as-built drawings, which focus solely on documenting the physical reality of the completed construction.
Why the Other Options Are Wrong
Option A: Actual locations of underground utilities
Actual locations of underground utilities are a critical component of as-built drawings because utilities are often relocated during construction due to field conditions, conflicts, or unforeseen obstacles. These final locations must be accurately documented for future maintenance and construction projects.
Option B: Field changes made during construction
Field changes made during construction are one of the primary purposes of as-built drawings. These drawings must capture all modifications, substitutions, and changes that occurred during the construction process to provide an accurate record of the final built condition.
Option D: Final dimensions of installed components
Final dimensions of installed components are essential information in as-built drawings because actual field dimensions often vary from design dimensions due to field conditions, material tolerances, and construction adjustments. These final dimensions are crucial for future renovations and maintenance.
Memory Technique
Think 'As-Built = As it Really IS' - only physical, measurable things that exist in the field, not the mathematical calculations that determined how to build it.

Florida Building Code Chapter 1, Section 107 - Submittal Documents, or AIA Document standards for as-built drawing requirements
