Estimate total seawall cost from length, height, width, material price per cubic foot, and construction price per linear foot, or solve a missing input. Choose the quantity to solve; the rectangular model includes only the material and construction components entered, not a complete project or lifetime budget.
Seawall Cost Formula
The following formula is used to calculate the cost of a seawall:
Variables:
- C is the cost of the seawall
- L is the length of the seawall
- H is the height of the seawall
- W is the width (thickness) of the seawall
- P is the unit price per cubic foot of the seawall material
- M is the unit price per linear foot of the seawall construction
To calculate the cost of the seawall, calculate the material cost as L × H × W × P (volume in cubic feet times the material cost in $/ft³). Then, calculate the construction cost as L × M (length in feet times the construction cost in $/ft). Add the two results together to get the total cost of the seawall.
What is a Seawall Cost?
A seawall cost refers to the total amount of money required to construct, maintain, and repair a seawall. This cost can vary greatly depending on several factors such as the size and length of the seawall, the materials used, the complexity of the design, the location, and the labor costs in the area. Material costs depend on the design, specifications, location and quotation; a universal ranking by material is not assumed here. Additionally, if the seawall is being built in an area with difficult terrain or high labor costs, the total cost will be higher. A complete lifetime budget also includes maintenance and repairs, but this calculator does not automatically include them or design, permits, site work, taxes or contingency. This can include costs for inspections, cleaning, sealing, or replacing damaged parts.
How to Calculate Seawall Cost?
The following steps outline how to calculate the Seawall Cost:
- First, determine the length of the seawall (in feet).
- Next, determine the height of the seawall (in feet).
- Next, determine the width (thickness) of the seawall (in feet), the unit price of material ($/ft³), and the unit price of construction ($/ft).
- Finally, calculate the Seawall Cost using the formula: Seawall Cost = (Length × Height × Width × Material Unit Price) + (Length × Construction Unit Price).
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem:
Use the following variables as an example problem to test your knowledge.
Length of seawall (ft) = 50
Height of seawall (ft) = 5
Width of seawall (ft) = 1
Material unit price ($/ft³) = 20
Construction unit price ($/ft) = 100
Seawall Cost ($) = (50 × 5 × 1 × 20) + (50 × 100) = 10,000
