TECHNICAL ADVISORY GROUP RECOMMENDATION <br />TAG CONTRACTING RECOMMENDATION FORM WP-42F1S IBI CO-09 20160708 3 <br />c.CenturyLink Concrete Removal – the Contractor removed concrete on a CenturyLink utility line <br />conduit ductbank, to facilitate continuing work and prevent standby time. This is work that was <br />originally scoped for CenturyLink. This cost and scope will be removed from CenturyLink’s <br />Contract. The total cost for this work is $10,021.00. HMG and CH2M have reviewed this cost and <br />find it acceptable. <br />d.Furnish and Install Signal Light Pull Boxes – The original design included signal wires located in <br />some of the street light pull boxes, but City of Fargo standard practice is to have separate pull <br />boxes for both traffic signal lights and street lights. This change adds the additional signal light <br />pull boxes to meet the City of Fargo standard. CH2M and HMG have reviewed this cost and find it <br />acceptable. The total cost for this change item is $15,400.00. <br />e.City Hall Construction Accommodation Deduction and Misc. Items – During the design phase of <br />this project the Engineer assumed per Owner direction that City Hall construction would not be <br />conducted concurrently with 42F.1S project Work. The Engineer worked closely with the <br />Diversion Authority Project Manager to develop Change Proposal Request 001. Changes to the <br />work include the following: <br />i.Remove concrete median crossing 3rd St North, adjust storm sewer in 3rd St North and 1st <br />Avenue, roadway reduction on 3rd St North and remove guard shack along 3rd St North. <br />ii.Gate valve added on watermain for 3rd Ave North tie in and watermain adjusted up 3rd <br />Ave North. <br />iii.Removal of copper pipe service to pump station – to connect water service to the 42A2 <br />pump station would have required boring a hole in the side of the pump station. The <br />Engineer of Record and City personnel determined that this would not be necessary, so <br />the copper pipe providing water service to the pump station under the F.1S contract was <br />not installed. <br />iv.During design the Engineer estimated the size of the concrete pad required for the <br />generator associated with the 42A2 pump station. Xcel Energy designed and installed a <br />transformer that was bigger than the preliminary transformer size estimate. The Engineer <br />of Record determined the transformer pad should be larger to accommodate the larger <br />transformer. <br />Details of the changes in scope can be found in the attached drawings and Change Order 09 Unit <br />Price Schedule dated 7/14/2016. The total net cost reduction of this change item is $134,999.01. <br />The changes in cost primarily deal with adjustment to the quantities of existing bid items; <br />however, three additional bid items are added to accommodate an additional 8” sanitary sewer <br />pipe and the removal of a guard shack on 3rd St North. <br />ATTACHMENT(S): <br />1.Change Order No. 9 <br />2.Contractor’s Change Proposal Dated 6/30/2016 (Differing subsurface conditions, City of Fargo Wall <br />Penetrations, CenturyLink Wall Penetration, CenturyLink Concrete Removal, Furnish and Install Light Pull <br />boxes) <br />3.Contractor’s Change Proposal Dated 7/6/2016 (City Hall Construction Accommodation Deduction and <br />Misc. Items) <br />4.Change Proposal Request 001 dated 7/5/2016 (City Hall Construction Accommodation Deduction and <br />Misc. Items)
