Consideration and Approval of Cooperative Contract: Purchase of one (1) D8 Dozer with a trash application on a National IPA cooperative purchase agreement with the City of Tucson--- Bid #12077 (Approve purchase of D8 Dozer from Empire Machinery in the amount of $724,025.86).

The Cinder Lake Landfill uses a Caterpillar D8 dozer daily to primarily push trash from the tipping area of the deck to the compactor working in the trash. It is also used to maintain the deck that the trucks drive on, push daily cover over compacted trash, maintain landfill slopes and construct other areas of the landfill. The equipment warranty and service is supported locally in Flagstaff by Empire Machinery.

The Solid Waste Section has $750,000 budgeted in its Fleet Capital line item  for the replacement of a D8 Dozer with a trash application this fiscal year.

3. Provide sustainable and equitable public facilities, services, and infrastructure systems in an efficient and effective manner to serve all population areas and demographics.

Option 1. Accept City of Tucson's cooperative purchase agreement with Empire Machinery as the lowest responsive, responsible bidder.

Option 2. Conduct our own competitive bid process.

Option 3. Continue to use the existing D8 dozer.

Solid Waste uses a D8 Dozer with a trash application daily on the tipping deck and working face of the landfill. The equipment pushes trash from the tipping area of the deck to the compactor on the working face, as well as grooming and maintaining the tipping area. This keeps the compactor working in the trash, keeps the deck smoother for truck traffic and improves overall safety. The Dozer also pushes cover material over the compacted trash, maintains the working face, outside slopes and builds roads and other areas under construction at the landfill.

The equipment being replaced is a 1998 D8 Caterpillar trash dozer which was purchased for $322,522. It has met the Fleet replacement criteria in terms of hours, life to date costs and repairs needed to continue its useful life. The Fleet Management criteria for dozers is 200 hrs. use per year, 9,000 hrs. lifetime. The landfill dozer is used 850 hrs. per year and has over 13,000 lifetime hours. The equipment is used daily and is in its third life, having been refurbished twice. The first refurbishment was done in November, 2009 at a cost of $143,652.86 through Empire Machinery. The second refurbishment was done in June of 2011 at a cost of $161,331.87 through Road Machinery. The life to date costs are currently $786,000. The dozer was presented to the Fleet committee and approved for replacement with funds from Solid Waste's fleet capital line item. The equipment is necessary to the daily operations at the landfill, being primarily used to push trash to the compactor, maintaining the deck and tipping area, pushing cover over the compacted trash, and other construction functions of the ongoing landfill design.

A third refurbishment could cost over $250,000, but is not recommended by the manufacturer, given the type of work the dozer does. Trade-in value for the current dozer is $80,000, which will decrease significantly in successive years. Fleet Services estimates $18,000 in maintenance costs and $50,000- $70,000 in undercarriage replacements  over the next year to continue use.

Community benefits include continued consistent quality customer service at the lowest possible user fees.
