Post-shore rental rates, reference shore capacity classes (never used to size a shoring design), and the engineering-required authorities.
This is the exact table the Scaffolding Cost Calculator runs on. Cite it as: Antero Trail, "Structural shoring rental rates and shore capacities", anterotrail.com/tools/reference/shoring-constants. Primary sources are listed with each value and at the bottom of the page.
Structural-shoring spec table for the scaffold interior_shoring scenario (PRP-CALC-3, shoring branch). Post-shore rental is priced in post-weeks off a single cited rental rate. Shore capacity classes are cited manufacturer safe-load ratings (Ellis, 2.5:1 factor of safety) shown for reference ONLY - the tool never selects a shore class or computes a count; structural shoring of a damaged building is an engineered system per the cited DHS/FEMA field guide. Frame shoring TOWER rental has no cited public rate and is quote-locally. All access dates 2026-07-12.
Post-shore rental rate and working capacity are from ONE rental catalog (Action Rentals). Rate and capacity vary by region and shore model; confirm locally. Monthly rate not published - the line is priced in post-weeks off the cited weekly rate.
REFERENCE ONLY - not used to size anything. Ellis Manufacturing heavy-duty adjustable steel screw shores; safe load capacity DECREASES as extended height increases; all include a 2.5:1 factor of safety. Shown so the narrative can honestly state the capacity range that exists, never to pick a shore for the user.
| model | safe load LB | height min in | height max in |
|---|---|---|---|
| STL-10HD | 56,000 | 10 | 14 |
| STL-19HD | 48,000 | 19 | 32 |
| STL-55HD | 34,000 | 55 | 80 |
| STL-103HD | 27,000 | 103 | 128 |
| STL-151HD | 25,000 | 151 | 176 |
Structural shoring of a damaged or compromised structure is an engineered system and must be designed by a registered professional engineer. This tool does not compute shore counts, spacing, or load ratings.
These calculators produce planning estimates from published public rate schedules. They are not a formal quote. Confirm equipment, access, and pricing with a licensed operator or rental yard before you rely on any number for an estimate.
