SUBJECT:
Street Maintenance Division Brush Chipper Replacement
PURPOSE:
To ensure that the Street Maintenance Division has adequate equipment to perform forestry operations.
BACKGROUND:
Brush Chippers are essential pieces of equipment mainly employed by Street Maintenance Division personnel to maintain the City's right-of-way trees. They quickly reduce tree limbs into wood chips for useful purposes such as erosion control and producing composting material and mulch.

During use on March 8, 2022, a failed axle fastener on 48-376 resulted in extensive main frame and body damage to the unit. The Fleet Maintenance Division inspected the machine and concluded that given the nature of the damage and the age of the machine, repair costs may possibly exceed the machine's value and that the continued safe use on public roads cannot be guaranteed. They also determined that there are several salvageable components that are still intact on 48-376 that could be used as replacement parts for the remaining machines.
In consideration of the machine's age and the findings of the Fleet Maintenance Division, I am recommending a replacement unit.
DISCUSSION:

Using Sourcewell contract 031721-VRM, Vermeer Midwest has proposed to supply an equivalent replacement brush chipper for $92,015.00. The quotation and an image of the proposed brush chipper are attached.
