Annex I - Material price estimates – 2010 The following table provides the average prices for the materials includes in various BofQs in this technology toolkit. The prices are averages in three different geographically distinct areas of Tanzania. Although the prices will change over time, they can be used for cost estimates for budgeting purposes.

IMPORTANT NOTE – The prices here in some cases vary significantly. A process will be undertaken to verify the accuracy of the prices in the final guidelines and toolkits across the three areas.
