| Reason for Recommended Action/Background |
General standards for all waste management units require the owner of a landfill to close each landfill cell following completion of waste placement. The Board approved the agreement with RJ Gordon Construction Inc. (RJ Gordon) on April 23, 2019 and closure construction activities began in the summer of 2019 and continued until wet weather suspended activities. Construction resumed this spring with activities nearing completion.
At the April 23, 2019 meeting the Board authorized the Director of the Division of Integrated Waste Management (Director) to approve all change orders up to the maximum allowable under state law. In the case of this project, the maximum allowable is $248,412.50. A number of unanticipated issues arose during construction activities which resulted in the Director approving change orders totaling $232,947.44. Approval of Change Orders 13 through 16 would exceed the Director’s authority and thus require Board approval.
Change Order 13 represents work to improve site drainage and modifications necessary due to unanticipated existing conditions. Change Order 14 provides for long term storage of excess geosynthetic materials that will be used for future landfill construction. Change Order 15 represents work to improve site drainage and access and work on the landfill gas collection system. Finally, Change Order 16 provides a better all weather road surface and incorporates a all weather yard suitable for material storage. |
