Slab Formwork Load & Shoring Grid Calculator
A practical, code-compliant utility to compute concrete deck dead loads, ACI 347 live loads, structural shore prop capacities, and safe maximum grid layout spaces.

Active Stress & Load Analysis
100 PSF
Based on 150 lbs/ft³ weight50 PSF
ACI 347 workers & fleet cap225 PSF
Combined with 1.5x safetyRecommended Spacing Grid: 4.5 ft × 4.5 ft
To safely support 225 lbs per square foot, telescopic props extended to 10 feet must be spaced on a maximum 4.5ft square grid layout layout.
Quantified Layout Bill of Materials (Projected)
Estimated inventory payload required to complete a single monolithic floor pour of 5,000 sq.ft.
434.7 Panels
Assumes lightweight 150x75cm primary slab decks.
271.7 Shores
Class D standards designed for exact 10ft ceiling height. To adjust heights, review components.
271.7 Heads
Quick-release strike plates to drop panels early while shoring props remain under stress loads.
Need precise certified layout diagrams?
Submit your real structural blueprints (.dwg/.pdf). Our engineers will model your slab thickness and calculate props counts.

Every floor thickness has a distinct load curve. Our CAD technicians calculate bending moments on wood or aluminum joists to optimize shoring layouts.

Rigid handset panels with precise lock interfaces guarantee zero deflection or standard deviation failures on the ceiling line below.
