TREE CM USA On April 13, 2015, sealed bids were opened for contractual treatment of selected parkway Ash trees in attempt to prevent their infestation by the Emerald Ash Borer. As authorized by the Village Board in 2009, we have been treating these trees annually with the hope that we will be able to preserve a small population of high quality ash trees in our parkways. Previously, we have treated all these trees with a product called Imidacloprid which must be applied each year. In 2012 we started transitioning to a program in which all the trees will eventually be treated every two years with a product called Tree -age. Our 2015-2016 specifications asked for pricing for treatments with Tree -age only. BID RESULTS Fifteen invitational bids were mailed and a notice was published in a local newspaper. Eight bids were received. The bid results were as follows: Contractor 2015 Price/Inch Extended 2015 Price (x 6500") 2016 Price/Inch Extended 2016 Price (x 6900") Total Kinnucan Tree Experts $4.25 $27,625.00 $4.25 $29,325.00 $56,950.00 TruGreen $4.71 $30,615.00 $4.50 $31,050.00 $61,665.00 Sunrise Tree Care $4.97 $32,305.00 $5.45 $37,605.00 $69,910.00 Nels J. Johnson Tree Experts, Inc. $5.95 $38,675.00 $6.08 $41,952.00 $80,627.00 Kramer Tree Specialists, Inc. $8.00 $52,000.00 $8.00 $55,200.00 $107,200.00 Winkler Tree & Landscape, Inc. $7.37 $47,905.00 $8.61 $59,409.00 $107,314.00 McGinty Bros., Inc. $7.48 $48,620.00 $8.51 $58,719.00 $107,339.00 Bartlett Tree Expert Co. $9.00 $58,500.00 $9.00 $62,100.00 $120,600.00 BID DISCUSSION In 2012 we put the treated ash trees into two groups to transition to the use of Tree -age, a two year treatment. This product is believed by many to be the most effective treatment for killing EAB larvae, and the unit price for treatment is reasonable. In 2015 we plan to treat Group A, consisting HAF0RESTRY\W0RD\2015\MEM0-EAB INSECTICIDE BID 2015.DOCX Page 2 of 2 Bid Results — EAB Insecticide Treatment - $30,125 April 15, 2015 of approximately 485 trees totaling 6500 diameter inches. In 2016 we plan to treat Group B, consisting of approximately 340 trees totaling 6900 diameter inches. We will soon re -measure all trees needing treatment. However, because the actual diameters of the trees might be slightly different from our estimates due to growth, we have added a small contingency of $2,500.00 to each year of the contract. Note that this year's costs are less than our previous contract. For years 2013-2014 the cost per inch was $4.87, in comparison to $4.25 for contract years 2015-2016. It should be noted that Kinnucan has worked satisfactorily for us in the past. In 2007, Kinnucan satisfactorily performed an EAB preventative treatment with a soil drench of Imidacloprid. Additionally, they have performed our white light installation contracts from 2012 through 2014. Finally, their submitted references were satisfactory. BID RECOMMENDATION There are funds available for this contract in the 2015 Budget. I recommend award of a two-year contract for Tree -age treatment to the low bidder, Kinnucan Tree Experts, in an amount not to exceed $30,125 for year one. Year two would be in an amount of $31,825.00 or whatever is appropriated for this purpose in the 2016 budget. I concur. Dave Hu.l an P.
