TECHNICAL ADVISORY GROUP RECOMMENDATION <br />2 TAG_CONTRACTINGRECOMMENDATIONFORM_WP-42A1-A3_CO-05_20160908 <br />DISCUSSION <br />Change Order No. 5 increases the Contract Price by $70,363.71 for the following items: <br />1. Overflow piping. The project design impacts an existing passive (i.e., non‐human interaction) overflow. <br />Environmental agency requirements have been recently updated, which require these passive overflows <br />to be eliminated whenever infrastructure upgrades occur. Since this project impacts an existing overflow, <br />the project will provide a means for utilizing a mobile pump to temporarily transfer overflow to the storm <br />sewer system on an emergency basis only. <br />The contractor proposed a Lump Sum cost of $10,363.71 for all labor and materials to install this <br />connection. HMG and the City of Fargo reviewed this amount and found it reasonable. This work is also <br />included in Work Change Directive 007 which is currently out for Chairman Vanyo’s signature. <br />2. T&M budget for asbestos removal. The project scope includes removal of two existing 78” corrugated <br />metal pipes that pass through the levee. At the time of bidding it was unknown that the pipes were <br />coated with an asbestos‐containing material (ACM), but during preparations for removal it was <br />determined that this is in fact likely. Subsequent testing by Terracon confirmed the presence of ACM. This <br />change item adds a budget of $60,000 to handle the additional costs for properly disposing of the ACM on <br />a Time & Material basis. The Contractor will be paid only for costs that are actually incurred, and only <br />after validation by HMG and CH2M field personnel. Unused budget will be deducted from the Contract <br />Price at project closeout. There is currently no known schedule change associated with this item. <br /> <br />ATTACHMENT(S): <br />Draft Change Order No. 5 <br /> <br />Submitted by: <br /> 9/1/2016 <br />Tyler Smith, P.E. <br />CH2M HILL <br />Project Manager <br />Metro Flood Diversion Project <br /> Date <br /> <br /> <br />Keith Berndt, Cass County Administrator April Walker, Fargo City Engineer <br />Concur: 08Sep2016 Non‐Concur: Concur: 02Sep2016 Non‐Concur <br /> <br />Mark Bittner, Fargo Director of Engineering Jason Benson, Cass County Engineer <br />Concur: 02Sep2016 Non‐Concur: Concur: 08Sep2016 Non‐Concur <br /> <br />David Overbo, Clay County Engineer Robert Zimmerman, Moorhead City Engineer <br />Concur: 02Sep2016 Non‐Concur: Concur: 02Sep2016 Non‐Concur <br /> <br />Nathan Boerboom, Diversion Authority Project <br />Manager <br /> <br />Concur: 02Sep2016 Non‐Concur: <br />
