Atkinson requested an additional $3.18 per ton in addition to costs for Bid Item No. 12 Subballast to provide this material. This added compensation is the result of a longer haul from KLB's original source to the source that could provide a material acceptable to BNSE New Bid Item No. 139 Subballast —Added Cost for Revised Specification, will be added to the con- tract and will be paid per Ton. The estimated quantity for this material is 2,160 Ton. New Bid Item No. 139 Subballast — Added Cost for Revised Specification, will be paid in addition to existing Bid Item No. 12 - Subballast. The Tukwila yard stockpile material was tested for contaminates on February 22, 2012 and the results indicated detectable levels of Lead and Arsenic. The detect levels for Arsenic and Lead are less than Statewide and Puget Sound background concentrations as reported in Ecology Publication 94 -115, Natural Background Soil Metals Concentrations in Washington State. The material is not considered a regulated waste however the detectable levels signifi- cantly reduced the receiving sites that will accept it. The Contractor's designated waste site of Cadman has confirmed they will not accept it after reviewing the test results. The removal of the stockpile is included in the quantity for Roadway Excavation Including Haul. However the permitted receiving site is a longer haul from the original waste site and the disposal fees are more. It was deemed prudent to time the removal of this material with the import of the subballast since the receiving site and pit site are in the same general area. To compensate the Contractor for additional haul and disposal of the material new Bid Item No. 140 — Dispose of Existing Stockpile Material, will be added to the contract and will be paid per Ton. The estimated quantity for this material is 1,150 Ton at a price of $18.51 per ton. Add the Following New Items to Contract CAG 11 -133: Description: Provide subballast material matching the composition and gradation of CADMAN High Rock Quarry 1 -1/2" CSBC. Unit price is to include all additional costs for material and haul- ing. Dispose of Existing Stockpile material while back hauling for delivery of Subbalast material for the west shoofly. Unit price is to include all costs for hauling and disposal. New Bid Items 139 and 140 represent full payment for all labor, equipment, and material nec- essary to construct the revised access road as described in this change order.
