REPORT: The questions posed by Council in relation to this tender are addressed below. How long would it take for us to move the material ourselves? In 2013 our internal forces, mostly Utilities staff, moved 867 tandem dump truck loads of fill material to Preston Sand and Gravel on Roseville road just outside of Cambridge. The total time to complete this task was 1714 hours and it had a total cost of $151,177.48. This equates to a cost of $174.37 per tandem load, each tandem load is approximately 14 metric ton of material. Therefore, per metric ton it cost $12.45. As a result, staff were pulled away from gas and water regulated maintenance activities as required by a gas and water distributor. This resulted in a domino effect of pushing back bi- annual and multi -year maintenance programs. Thus far this has resulted in our contracting out a portion of our annual hydrant maintenance checks in 2014 and we are still behind in a few multi -year maintenance programs (e.g. water valve and gas valve operational checks). It will not be possible for staff to complete the required annual programs and move the material as well. Would it be less cost to move it ourselves? No. Our tendered low bid was $139,760 for 1000 tri -axle loads. Tri -axle trucks hold approximately 24 metric ton of material. Therefore, per tri -axle load the cost is $139.76 and per metric ton is $5.82. Our cost last year using internal staff was $12.45 per metric ton. Therefore, it costs us roughly double to use our forces to do this work. This is mainly due to the fact that we do not have tri -axle trucks to do the work. Where are the sites it is being shipped to? This all depends on who is awarded the tender. The tender description of work is to load, remove and dispose of the materials. Also outlined in the tender, we have the bidding contractors sign off that they agree and shall comply with the re -use options as detailed in the two stockpile reports as prepared by MTE. Do we tell the contractor where to take it? Not directly. As stated above, we tell them and make them sign off that they will only re -use the material in accordance with re -use options as detailed in the reports. How long would it take us to find our own sites? Historically we utilized many different small private sites. However, due to the liability of potentially contaminated soil, it is now brought to the KOF for testing and then we try to dispose of it depending on the test results. Last year we were able to take the material to a quarry site near Cambridge. However, this year they are not accepting any fill. This material has been tendered out twice in the past and both of these times there were no bidders. This year we thought we were going to be able to take some of the material to the old Budd plant site, however, after approximately 15 loads they deemed the material was too wet for their purposes. Finding a regular long term site to dispose of the material has not been possible. Are we reusing it or does it belong to the Contractor when it is taken away? It belongs to the contractor to remove and dispose of the material. Reusing it is not realistic as two costly and impractical processes would need to be completed for the material to be able to be re -used. Firstly, it would require continual manipulation by staff to rotate the material by mechanical means (front end loader) to dry out the material as it is currently too wet to be used in a roadway. In freezing weather conditions this manipulation is not feasible as the material solidifies into a block of ice. Lastly, the material is a combination of granular material and native soils. This material would need to be screened to meet the proper grain size distribution to meet requirements to be once again used in the roadway. The screening process will still generate waste material which would need to be trucked away. The amount of waste will be dependent on the initial quality of the material.
