`LH = ( "N" " bags" * (5 min)/(bag)) "/" ( "P" " workers")`

Enter a value for all fields

The Time Required to Fill Sandbags calculator estimates the amount of time to fill (labor hours) a number (N) of sandbags.

INSTRUCTIONS: Enter the following:

• (N) Number of Sandbags
• (P) Number of People filling Sandbags

Labor Hours (LH): The calculator returns the number of hours required by the workforce to fill the sandbags. 

Sandbag Calculators:

• Compute the number of sandbags for flood dike
• Compute the amount of sand needed for a flood dike
• Compute the number of sandbags for a one bag deep wall
• Compute the amount of sand needed for a one bag deep wall
• Compute the time (labor hours) to fill and stack sandbags
• Compute the weight of an number of filled sandbags.
• Compute the weight of a volume of sand (wet, dry, loose, packed)

The Math / Science

The Labor Hours to Fill Sandbags is based on the average of twelve (12) sandbags filled in an hour per person (P).  The Labor Hours to Fill Sandbags calculator helps you determine the amount of time that a group of people will need to fill and stack sandbags on site to build a sandbag wall.  It's based on the paper Sandbagging for Flood Protection by Dr. Hellevang captured int he Sandbag Wall Calculator. Note: The results of this Labor Estimate Calculator assumes continuous work, meaning no significant work stoppages waiting for supplies or taking long breaks (like a night's sleep).  These factors must be taken into consideration in larger projects.

To be prepared for a flood with a sandbag dike, you need:

• a good plan to build a sandbag dike,
• to estimate the number of sandbags you will need to build the dike,
• to estimate how much sand you need to fill the sandbags, 
• to have the materials on site, and 
• to estimate how much time it will take to build the sandbag dike with the help you have.
