Rebar Pricing

Overview

The Rebar API manages pricing rates for reinforcing steel (rebar) used in concrete items. Rebar costs are automatically calculated based on bar size, spacing, and concrete dimensions.

}

Response

{
  "id": "uuid",
  "size": "#6",
  "message": "Rebar rate created successfully"
}

Roles: ADMIN

Required Fields:

• size (string) - Rebar size (#3, #4, #5, #6, #7, #8, #9, #10, #11)

#3	0.375"	0.376	Light slabs, walls
#4	0.500"	0.668	Residential slabs, footings
#5	0.625"	1.043	Commercial slabs, beams
#6	0.750"	1.502	Heavy slabs, columns
#7	0.875"	2.044	Structural beams
#8	1.000"	2.670	Heavy structural

warning

Deleting a rebar rate will affect cost calculations for concrete items using that size. Update pricing instead of deleting.

Rebar Calculation Logic

When a concrete item includes rebar, the cost is calculated as:

// 1. Calculate linear feet of rebar needed
const area = length * width; // Square feet
const spacing = 12; // inches (e.g., #4 @ 12" o.c.)
const barsInOneDirection = Math.ceil((length * 12) / spacing);
const barsInOtherDirection = Math.ceil((width * 12) / spacing);
const totalLinearFeet =
  barsInOneDirection * width + barsInOtherDirection * length;

// 2. Calculate weight
const weightPerFoot = 0.668; // For #4 rebar
const totalWeight = totalLinearFeet * weightPerFoot;

// 3. Calculate cost
const pricePerPound = 0.85;
const rebarCost = totalWeight * pricePerPound;

Example Calculation

Slab: 50' x 40' with #4 rebar @ 12" o.c. both ways

Bars lengthwise: ceil(50 * 12 / 12) = 50 bars
Bars widthwise: ceil(40 * 12 / 12) = 40 bars

Linear feet lengthwise: 50 bars * 40' = 2,000 LF
Linear feet widthwise: 40 bars * 50' = 2,000 LF
Total linear feet: 4,000 LF

Weight: 4,000 LF * 0.668 lb/ft = 2,672 lbs
Cost: 2,672 lbs * $0.85/lb = $2,271.20
