Purchase of New Schwarze CNG Model A7 Tornado Street Sweeper
Approve issuance of purchase order in the amount $323,978.12.
For over 50 years, the City has utilized a small fleet of three sweeping machines to sweep all City streets once per week. Two street sweepers were used in a frontline capacity, while one was used as a back-up or reserve role. Two of the sweepers were put into service in 2011, while the third was put into service in 2001. Since street sweeping machines are high maintenance units and are in continuous operation for 12 months out of the year, the sweepers typically have a 10-year life expectancy.
In March 2019, City Council directed staff to implement a street sweeping pilot program that changed sweeping frequency from once per week to twice per month. This pilot program is still in effect and requires the use of two street sweeping machines with one serving the frontline role and one as a back-up. Since the oldest sweeper was 18 years-old at the time the pilot program began in March 2019, the decision was made to sell the unit at auction because the engine was experiencing significant drivability issues; hopper was full of rust and rotting away causing the rear door to not function; a high number of hydraulic leaks, electrical failures and upgrades needed to keep the unit running. The Public Works Department sold this unit in public auction on October 09, 2019 for an amount of $3,450. The decision was made to not immediately replace this unit since the City Council had not made a final decision on street sweeping frequency, which would have an effect on how many sweeping machines would be needed.
However, within the last two years, the other two 10 year-old street sweeping machines have been experiencing significant mechanical and maintenance issues of their own. At one point, earlier this year, both machines were out for repairs at the same time and staff had to quickly rent a street sweeping machine just to keep up with sweeping. Given the immediate need to have at least one very reliable street sweeping machine, staff is now recommending replacing the previously surplused 2001 street machine with a new machine. The new machine would serve as the front-line machine and staff will keep both 10 year-old machines as back-up reserves until such time City Council makes a final decision regarding street sweeping frequency. A decision to replace one of the 10-year-old machines would be made at a later date.
Staff participated in demos for two street sweeping machines, which included the Tymco and Schwarze. After evaluating the features and cost, staff has selected the Schwarze CNG Model A7 Tornado Street Sweeper. This sweeper was offered at a cost of $323,978.12, which was $45,427.83 lower than the Tymco and provided additional features such as a duel fueling system; fifty additional horsepower; stainless steel hopper with lifetime warranty; LED traffic guide arrow board; LED strobe for the cab; thirty additional gallons of water capacity for the water tank; factory training for two City employees; and two hundred additional hours of warranty on the sweeper. If approved, given the time it takes to build the unit, expected delivery to Brea would be approximately eight months from the date of issuance of the purchase order. Given the changes in Air Quality Management District regulations, the new unit shall be powered by Clean Natural Gas.
The total expenditure for this purchase is $323,978.12. Funding is available to cover the cost of this purchase in AQMD Fund 240, which have been appropriated for this purpose. This price is through the Sourcewell Contract No. 122017-SZW. The not-to-exceed amount includes everything necessary to provide a fully functional new street sweeper. There is no General Fund Impact.
