Chipulukusu School Construction

We received a very detailed price list for construction of 2 classrooms for the Chipulukusu school today. The 150+ kids at the School desperately need classrooms. Right now all 4 classes K-3 meet in the same room. How's that for a quiet place to study?? The community has already dug the foundation trenches and now they've gathered cost estimates for construction. The total cost for 2 classrooms and a small office is projected to be $28,000 with the community contributing a significant part of the labor.
