A seawall is a critical structure that protects coastal properties from erosion and water damage. If you're planning to build a seawall, knowing the cost beforehand is essential. Our Seawall Cost Calculator helps estimate expenses based on materials, labor, and additional costs.

How to Calculate Seawall Cost?

The total cost of building a seawall depends on the dimensions, material costs, labor costs, and extra expenses. Here's the step-by-step calculation process:

1. Calculate Seawall Volume

To determine the amount of material needed, we calculate the seawall's volume:

$V = L \times H \times W$

Where:

• $V$ = Volume in cubic feet
• $L$ = Length of the seawall (ft)
• $H$ = Height of the seawall (ft)
• $W$ = Width of the seawall (ft)

2. Convert Volume to Desired Unit

Depending on the material cost unit, volume needs to be converted:

Cubic Meters (m³):

$V_{m^3} = V \times 0.0283168$

Cubic Yards (yd³):

$V_{yd^3} = \frac{V}{27}$

3. Calculate Material Cost

Material cost is calculated based on the selected unit:

$C_m = C_{unit} \times V_{converted}$

Where:

• $C_m$ = Total material cost
• $C_{unit}$ = Cost per cubic unit (m³, yd³, or ft³)
• $V_{converted}$ = Volume in the corresponding unit

4. Calculate Labor Cost

Labor cost depends on how workers charge:

Per foot:

$C_L = C_{per\_ft} \times L$

Per meter:

$C_L = C_{per\_m} \times (L \times 0.3048)$

Fixed project rate:

$C_L = C_{fixed}$

5. Calculate Total Cost

The final cost is calculated as:

$C_{total} = C_m + C_L + C_{extra}$

Where:

• $C_{total}$ = Total seawall cost
• $C_{extra}$ = Additional costs (permits, site preparation, etc.)

Example Calculation

Let's say we need to build a seawall with:

• Length = 50 ft
• Height = 6 ft
• Width = 2 ft
• Material cost = $100 per yd³
• Labor cost = $20 per foot
• Additional costs = $500

Step 1: Calculate Volume

$V = 50 \times 6 \times 2 = 600 \text{ ft}^3$

Step 2: Convert Volume to Cubic Yards

$V_{yd^3} = \frac{600}{27} = 22.22 \text{ yd}^3$

Step 3: Material Cost

$C_m = 100 \times 22.22 = 2222$

Step 4: Labor Cost

$C_L = 20 \times 50 = 1000$

Step 5: Total Cost

$C_{total} = 2222 + 1000 + 500 = 3722$

Thus, the total estimated seawall cost is $3,722.
