N/A
Beam spacing (if repetitive)
This is a single beam — not repetitive
Repetitive — spacing:

Step 7 of 8
Performance criteria.
Deflection limits, vibration, fire rating, and appearance requirements. The difference between a beam that works on paper and one that works in the building.
Deflection limit — live load
L/360 (code minimum)
L/480 (standard — default if unknown)
L/720 (stringent — tile floors, plaster ceilings below, sensitive use)
L/240 (roof, non-occupied)
L/180 (roof, no ceiling attached)
Custom
Not sure — we'll default to L/480
Deflection limit — total load
L/240 (roof only)
L/360 (code minimum — floors)
L/480 (standard — default if unknown)
L/720 (stringent)
Custom
Not sure — we'll default to L/480
Vibration concern
No — standard occupancy
Yes — sensitive use (home office above, open floor, long span)
Yes — tile or stone floor on this span
Yes — owner has expressed concern about bounce / Feel
Not sure
Fire rating
None required
1-hour fire rated assembly
2-hour fire rated assembly
Heavy timber (Type IV) — exposed
Not sure — we'll determine from code
Appearance
Concealed — hidden in wall or floor assembly
Exposed — architectural grade, visible
Exposed — industrial / Character is acceptable
Wrapped — beam will be finished with drywall or trim
Not sure yet
Camber
None required
Standard mill camber is acceptable
Specific camber required
Not sure what this means — recommend based on span
Creep / Long-term deflection concern
No — standard loading duration
Yes — sustained heavy load (storage, mechanical, water feature)
Yes — long span with permanent dead load concern
Not sure
Step 8 of 8
Additional beams & submission.
Batch multiple beams into one request, attach plan references, and submit. Most projects have more than one — this prevents multiple separate submissions.
Add another beam to this request?
No — this is the only beam
Yes — add another beam
If yes, you'll be taken back to Step 2 to enter details for the next beam. Each beam is numbered and tracked separately in the summary. For projects with 5+ beams, a full structural layout engagement may be more efficient.
