Staff Report Approve Change Order No. 1 to Contract C23310H - Monterey at i-10 Page 2 of 3 June 12, 2014 Backqround On January 23, 2014, City Council awarded Contract C23310H to Powell Constructors, Inc., (Powell) in the amount of $7,037,417.35 and approved a 10 percent contingency. The Notice to Proceed was issued on March 31, 2014. Powell has been working diligently with property owners and various government and utility agencies. In reviewing the current field conditions, the construction management consultant has discovered that several contract items were overestimated or were no longer necessary. Also, Powell has proposed different form liner for the rabbit imprint on the tieback walls. This resulted in a net credit of $167,312.87. Unfortunately, the contractor has encountered some unforeseen conditions as well, such as an increase of contract bid item amount for the shoulder rumble strip, removal and reconstruction of 4-foot shoulder, upsizing the signal pole as the original specified pole was inadequate, the need for temporary lighting installation, the removal of recently Caltrans installed concrete barrier and an unidentified underground abandoned vault which were not identified on the approved plans and specifications. The total cost for these items is $160,996.74. This will result in a credit of $6,316.13 so the revised contract with Powell is $7,031,101.22. IID is the electrical provider for this project. To date the City has paid a total of $71,125.71. Additional invoices in the amount of $56,087.23 are now due. Staff has met with IID again recently and has been assured that they are working diligently to provide the services to the project without causing delay. Due to the amount of utility costs, staff requests Council ratify the $71,125.71 paid to IID and approve the remaining fee. In anticipation of the potential to cancelled council meetings in July and August, staff requests that the City Manager be given the authority to approve construction change orders up to fifty percent of the approved contingency for the duration of the project to avoid any potential delay claim by the contractor. The project is approximately twenty percent complete. Any change orders approved by the City Manager will be brought to City Council for ratification at the next available meeting. Fiscal Impact This fiscal impact associated with this action results a small credit with Powell construction contract, additional IID required fees, and the potential of additional Change Orders as appropriate and approved by the City Manager.
