TECHNICAL ADVISORY GROUP RECOMMENDATION <br />TAG_CONTRACTING_RECOMMENDATION_FORM_WP-42F1S_IBI_CO-14_2016-1110 3 <br />2.City of Fargo Library Landscaping – The majority of the landscaping work in the area of the project <br />will occur under a separate work package (WP 42G). Due to other non-Diversion Authority work in the <br />42F1S project area, the work package 42G landscaping is scheduled to occur in either 2017 or 2018 to <br />prevent relandscaping of areas that are still under construction. The City of Fargo requested that a <br />small section of landscaping, that will not require rework, be added to this work package. The total <br />cost of this change item is $3,462.80 and includes the cost for installing mulch, rocks, and edging at <br />the NW corner of 1st Ave and 3rd St. HMG personnel have reviewed the cost and find it acceptable. <br />3.Epoxy Paint – The project team determined that epoxy paint and epoxy messages should be installed <br />on 3rd St. The Contract does not include a bid item for epoxy painting The total cost of this change <br />item is $714.00 The portions of 3rd st that are striped with epoxy paint will not be striped with <br />grooved plastic film. HMG personnel have reviewed the cost and find it acceptable. <br />4.Differing Site Conditions – During the month of September the Contractor encountered additional <br />unsuitable soils that cannot be used on-site. This change item includes labor and equipment costs for <br />the removal of unsuitable soils during the month of September and adds $16,200.39. HMG personnel <br />have reviewed the cost and find it acceptable. <br />5.3rd Street Lighting Modifications – The Contract Plans call for the reuse of existing light bases on the <br />east side of 3rd St; however, the light bases are over 50 years old. The Project Team determined that <br />new light light fixtures should be installed. The total cost for this change item is $5,406.50 and <br />includes labor, materials, and equipment costs for installing the light fixtures. HMG personnel have <br />reviewed the cost and find it acceptable. <br />6.1st Ave Plaza Bench Modifications – The 1st Ave plaza work includes concrete benches. After <br />installation of the benches it was realized that one bench was too low and another had incorrect <br />alignment. The incorrect installation was a result of an error in the plan drawings and incorrectly <br />approved shop drawings. The total cost of this change item is $8,317.15 which includes the labor, <br />material and equipment costs associated with fixing the plaza benches. HMG personnel have <br />reviewed the cost and find it acceptable. CH2M, HMG and the Owner’s technical staff will include this <br />error in an on-going review of design Quality Control and the Engineer’s financial responsibility for <br />changes resulting from design issues across the program. CH2M will present the findings of this <br />review to the board at a future date. <br />7.Topsoil Import – The intent of the plans was for the Contractor to use existing soils on-site, which <br />during construction have been found to be unsuitable. Soils throughout the site contain large <br />quantities of brick, glass and other debris. Additionally, soils in the Case Plaza lot had been previously <br />chemically contaminated. Because of the large amount of unsuitable material the Contractor does not <br />have enough topsoil from the site and needs to import from an offsite location. The total cost of this <br />change item is $40,184.00 for 1,600 cubic yards of imported top soil. This change item includes two <br />new unit rate line items to accommodate project needs. The Contractor will be paid based on the <br />actual quantity of material imported. HMG personnel have reviewed the cost and find it acceptable. <br />8.Temporary Straw Mulch – This change item adds the option to use straw mulch for temporary cover <br />over the winter months. Hydromulching is the intended final stabilization method required for <br />erosion control; however, it is more expensive than straw mulch. Because this area will be disturbed <br />with future construction activities the project team determined that straw mulch should be placed for <br />cover during the winter months. The total cost of this change item is $510.00. HMG personnel have <br />reviewed the cost and find it acceptable.
