STATEMENT OF WORK
Ecology Blocks
Scope:
This scope of work (SOW) covers the purchase of Ecology Blocks
Background:
Ecology blocks are commonly used as barriers, erosion control, and foundation support for
the US Army Corps of Engineers. These blocks can be placed together permanently or pieced
together temporarily which gives the COE flexibility and a multi-use approach when using
them to address the COE mission when utilizing these blocks for various projects.
Justification:
The ecology blocks are currently being planned to be placed at the base of slopes that are
above project infrastructure and where project personnel travel. We are concerned rocks can
come down those slopes and limit access to our facilities, represent safety hazards to Corps
equipment, vehicles, and people.
