Items <br />DISCUSSION <br />1.Change Order No. 9 adds new and modifies existing scope elements to total a decrease of $55,349.74 to <br />the Contract Price. The Change Order consists of the following items: <br />a.Differing Subsurface Conditions – While digging on-site the Contractor has encountered <br />numerous differing subsurface conditions associated with debris and materials previously buried <br />on-site. The Contractor cannot use soil containing large amounts of debris, so it must be removed, <br />hauled and disposed. It was known during bidding that large amounts of buried material existed <br />on the site, but quantification of that material was not possible prior to work start. The Owner’s <br />Representative and City of Fargo Project Manager agreed to bill this work on a Time and Materials <br />basis to facilitate timely decisions and prevent standby time. This change item was originally <br />presented to the Diversion Authority in Change Order No. 8 for differing subsurface conditions <br />costs incurred from Project Start through May 28, 2016. That amount was $139,428.30. <br />i.For Change Order No. 9, covering the period from May 28, 2016 through June 30, 2016, <br />the differing subsurface conditions time and material costs incurred were $48,247.52, <br />resulting in a cost to date of $187,675.82 for this line item. <br />ii. Additional differing subsurface conditions costs are anticipated to be incurred as other <br />portions of the project site are excavated. A budget for future differing subsurface <br />conditions costs is not included in this change order. Actual future differing subsurface <br />conditions costs will be included in a future change order. <br />iii.The Owner’s Representative reviewed Time and Materials rates prior to acceptance. HMG <br />and CH2M have reviewed this change and find it acceptable. The costs are broken down <br />into the following categories: <br />1.Prime Contractor removals (IBI) <br />2.Earthwork subcontractor removals (Reiner) <br />3.Removal of 60” steel casing around sewer pipe not previously identified in the <br />plans <br />4.Removal of concrete beneath a water line not previously identified in the plans <br />b.Wall Penetrations – The City of Fargo requested that additional wall penetrations be placed <br />through the floodwall to accommodate future utility use. The price includes labor and materials <br />to install the link seals and grouting of the conduit. CH2M and HMG have reviewed this cost and <br />find it acceptable. The total cost for this change item is $5,980.75.
