Minutes of the Arden Hills Regular Council Meeting", May 14, 1990 Page 7 . CHANGE ORDER (Cont'd) Goudreault advised that when Delta prepared the well abandonment specifications there was not substantial informtion located relating" to wells # 3 and #4, therefore, assumptions were mde by Delta regarding" the depth and diameter of these wells. He ~lained another problem =ed when sand was found at the bottom of the wells and to properly abandon the wells this sand will have to be pumped from the wells, then the wells will be televised, an analysis be completed and then process for abandonment will begin. Goudreault stated that Bergerson-caswell provided an estimte of additional costs for completion of the well abandonment and that it is based on an estimted two and one-half days of work per well; it is not a fixed rate. The Clerk Administrator stated that Engineer Maurer reviewed this mtter and ~ressed concern that the pump for the wells was not removed to determine the depth of the wells; also noted the 6 inch casing" on the well usually indicates a commercial well and normally those wells are deeper than originally estimted. Goudreault stated pump removal is not usually done prior to subnission of a bid quote and he was basing" the depth of the well on his informtion relative to depths of wells in this area; noted he has worked on a mnnber of projects for TCAAP and is familiar with this area. Councilmember Malone ~essed frustration that the city hired Delta to provide the ~ise on well-abandonment and this is the second change order that has . =ed after Delta's assessment of the site. He questioned if any other problems are foreseen which will require additional funds to be allotted to the demolition. Mayor sather also ~ressed dissatisfaction with Delta allowing" the contractor to underground storage tanks from another site for disposal at the Kem Milling" site. Goudreault stated he did not foresee any mjor problems requiring additional funding" at this time and that Delta was not aware of the contractor's intent to bring" in additional storage tanks for disposal purposes. He advised that Darrell Ohman has been placed in charge of the site demolition and he will keep the Council informed of all activities. Attorney Filla commented that Delta is representing" the city not the contractor and as the City's consultant it is the consultant's responsibility to convey to the contractor the City's concern regarding" the additional costs of well abandonment. Filla referred to the bid quote contract tenns which relate to "change orders"; the contract two alternatives for resolution of change orders, one method would be to bill the city on a time and mterials basis and the other would be to negotiate a sum of money. Goudreault ~lained that he assumes responsibility for the miscalculation of the depth of the two wells; suggested the City could solicit bids for follow-up action from sub--contractors, with the additional knowledge obtained regarding" the . wells, and select a different contractor or the city could mintain the =ent contractor and pay only for actual hours spent on the job, on a time and mterials basis. He advised if the City prefers to re-bid the well abandonment, Delta will not charge for this service. Mayor sather suggested the Council invite the contractor to the next worksession meeting" to discuss the mtter.
