Bamboo Cost per lineal foot = $3.67 Projected lineal footage = 1000 feet (with waste)
Rebar Cost per lineal foot = $0.40 Projected lineal footage = 120 feet
Mortar Cost per bag cement = $10.00 Projected number of bags = 5
Wire Cost per lineal foot = $0.06 Projected lineal footage = 1,730 feet
Total Cost = $10.80 per square foot

Bamboo, No. 3 rebar, 14 gauge wire, and mortar are very effective materials for the typical connections necessary our Haitian home.
All materials are affordable, readily available, and safe to build with.
Controlled failure modes in steel components allow for inconsistencies in bamboo and open door to standardize bamboo poles as a reliable building material.
