jesse.masten@eaglecounty.us   970‐328‐3472    RE:  Scope of Work and Cost Estimate for Special Projects at Eagle County Solid Waste & Recycling    Mr. Masten:    Souder, Miller & Associates (SMA) is pleased to present the following scope of work and cost estimate to  Eagle County Solid Waste & Recycling for the additional engineering services discussed at the April 10,  2019 on‐site meeting. The projects addressed in this letter include the following:    1.0  Design Review  2.0  Leachate Holding Pond Design and Bid Document Preparation  3.0  Module 9 Engineering Cost Estimate  4.0  Summary    Each project is discussed in detail in the following sections. The attached spreadsheet details SMA’s cost  estimates for engineering services as required.  1.0  DESIGN REVIEW  In 2017, SMA survey staff were present at to Eagle County Solid Waste & Recycling to place stakes at the  design toe of waste along the northeast side of the landfill. Through this survey, it was discovered that  the existing toe of waste was not at the designed location, and the existing access road is within the landfill  footprint and at a lower elevation than the design toe of slope. SMA will prepare an exhibit with various  options regarding this discrepancy, including:   Construct waste slopes at approximately 3.5:1 from the edge of the existing ditch which runs  alongside the access road and leave the access road as it is.   Construct waste slopes at approximately 3.0:1 from the edge of the existing ditch to elevation  7430, then slope the waste at approximately 4:1 to the top of waste.   Extend the design toe of waste until it reaches existing ground and move the access road and  ditches farther northeast. Please note that this option would require a slight expansion of the  landfill footprint.   Elevate and move the existing ditches and access road so that they properly align with the current  design toe of slope. With this option, a complete redesign of the access road and ditches will be  provided  by  SMA  so  that  the  amount  of  cut  and  fill  required  to relocate the road can be  determined.    DocuSign Envelope ID: 4EA0F10A-3EF5-41C5-8603-8E09C3EAA13B Mr. Jesse Masten  Scope of Work and Cost Estimate for Special Projects  Page 2  2.0  LEACHATE HOLDING POND DESIGN AND BID DOCUMENT PREPARATION  2.1  REDESIGN  Eagle County intends to construct a portion of Module 9 in 2021. For the new cell (Module 9A) to function  properly, the existing leachate holding pond must be modified to accept more leachate. SMA will redesign  the leachate holding pond so that it can manage leachate generated from November through April and a  design storm over Module 9A when devoid of waste.  In addition, the redesign of the leachate holding pond will include converting it to a Type B waste  impoundment. The pond will be dual‐lined and contain a leak detection system.  Time is also allotted in this section for communication with the Colorado Department of Public Health and  Environment (CDPHE) regarding the redesign.    Also included is the time required to provide multiple design iterations for review by Eagle County.  It is  assumed that several adjustments will be made to the design and time will be required to discuss the  adjustments with Eagle County. Three site visits were included.  It was assumed that the meetings will  occur during regularly scheduled monthly compliance meetings, so the project manager’s time is not  included.  2.2  BID DOCUMENTS  In order to construct the leachate holding pond in 2020, SMA will prepare the necessary bid documents  for the construction project by the end of 2019 so that the bidding process may begin at the start of 2020.   The following items will be included in the bid package:  Engineering Cost Estimate Construction Bill of Quantities (derived from the engineering cost estimate) Project Specifications Construction Quality Assurance/Quality Control (CQAQC) Plan Scope of Work Construction Drawings In addition, time was allotted in this section for adjustments to bid documents and discussion with Eagle  County.  3.0  MODULE 9A COST ESTIMATE  As requested by Eagle County, a cost estimate will be prepared for the construction of Module 9A,  including costs for the new access road and stormwater management. This cost estimate will include  estimated costs from a third‐party contractor for the construction of the entire module. In addition, SMA  will prepare costs related to developing the bid documents and CQAQC services.  It is anticipated that communication with CDPHE will be required prior to construction of Module 9A. As  was discussed during the April 10, 2019 meeting, there is a possibility that CDPHE will require a revised  DocuSign Envelope ID: 4EA0F10A-3EF5-41C5-8603-8E09C3EAA13B Mr. Jesse Masten  Scope of Work and Cost Estimate for Special Projects  Page 3  liner system for Module 9A. Therefore, time was allotted for communicating with CDPHE and revising the  liner system.  4.0  SUMMARY  The estimated costs for the various items described in sections 1.0 through 3.0 are presented in the  attached spreadsheets. The current SMA fee schedule was utilized for the preparation of this budget.  While we believe that these fees are realistic, unforeseen obstacles and changes to the task list may result  in costs higher or lower than those estimated.  If you have any questions or comments, please do not hesitate to  contact  us.  Thank  you  for  this  opportunity to serve Eagle County Solid Waste & Recycling.  Sincerely,
