Tamarack St. Reconstruction Project Commission Memorandum REPORT TO: Honorable Mayor and City Commission FROM: Bob Murray, Project Engineer Rick Hixson, City Engineer SUBJECT: Approve Resolution 4969 authorizing Change Order No. 1 to the East Tamarack Street Reconstruction Project. MEETING DATE: October 15, 2018 AGENDA ITEM TYPE: Consent RECOMMENDATION: Approve Resolution 4969 authorizing Change Order No. 1 to the East Tamarack Street Reconstruction Project. BACKGROUND: Attached is a copy of resolution 4969 and change order number 1 for the above referenced project. If poor subgrade materials are encountered on the project, the contract documents call for the poor material to be removed and replaced with imported gravel. The presence of a shallow gas main on the west end of the project will not allow that method to be used. This change will add a unit price item to use geogrid for subgrade stabilization in that area. At the estimated quantity of 358 square yards, the change will result in an increase in the contract price of $1,521.50. There is no change to contract time. The final recommended change in cost and time for these items is reasonable and commensurate with the work involved. UNRESOLVED ISSUES: None ALTERNATIVES: As suggested by the City Commission. FISCAL EFFECTS: This change order increases the contract amount by $1,521.50 from $1,627,588.00 to $1,629,109.50.
