Wasp is a general term referring to a group of related insects in the order Hymenoptera (wasps, bees and ants). Although some wasps are solitary, i.e. just one adult female per nest, this publication discusses social wasps, i.e. multiple individuals sharing one nest. Most social wasps belong to the family Vespidae (sometimes referred to as vespid wasps). There are three types of social wasps in the upper Midwest.
Blanket Purchase Agreements (BPAs) 13.303-1 General. A blanket purchase agreement (BPA) is a simplified method of filling anticipated repetitive needs for supplies or services by establishing charge accounts with qualified sources of supply (see Subpart 16.7 for additional coverage of agreements).
With a Purchase Agreement, normally what you find is language that says that as long as the purchase order issued complies with the terms of the Purchase Agreement it is issued under, that order is binding and enforceable. The difference between the two has nothing to do with the time period involved. A Blanket Purchase Order may be for long period and a purchase agreement may be for a very short period. The difference has nothing to do with the volume involved.
