Run-in Calculator
Run-in Calculator had material estimate functions and data associated with building an agriculture building for animal shelter, aka Run-in.
- Metal for Shed (Roof and Walls): Computes the number and length of metal panels needed for the roof and walls of a run-in based on the dimensions.
- Purlins and Girts for a Shed: Computes the number of purlins (roof) and girts (wall) boards needed for a run-in based on the dimensions.
- Screws for Metal Shed or Run-in: Computes the number of metal screws needed to connect panels to framing on a run-in based on the dimensions.
A run-in is a open sided shelter for farm animals such
as horses, sheep and cattle. It provides a wind break and rain/snow shelter for the animals.
Considerations
- ORIENTATION: Have the open face away from the prevailing winds. In the northern hemisphere, this typically means facing it south-east to shield from north-west winds.
- LOCATION: Have it where there is some slope for water drainage, but not too steep for construction ease and general comfort of the animal. The animals WILL stand in these buildings for many hours (days) on end. You do not want them standing in muddy water. Also, you may want to build your run-in close to fences or gates that will make it easier for you to reach your animals in bad weather.
These are 
basic pole-barn construction with beams, rafters, purlins and girts. Note the diagonals to support the shape in high wind conditions. Metal roofing and siding in Ag Panels have become more and more common due to their cost, strength of materials, and life span of construction.
