The additional construction administration services are needed due to the extended effort required <br />to close-out the project. The project completion was determined to be around the first week of May 2013, <br />approximately four months later than originally anticipated, (an additional two months beyond what was anticipated for <br />Change Order Request No. 3 based on the Contractor's submitted project schedule at that time). We have also included, <br />(as an Allowance Item), effort to continue coordinating with and supporting the City of Prescott and the Airport through <br />miscellaneous contractor claims. This effort cannot be worked without prior approval from the City/Airport. <br />The Dibble Engineering team additional efforts have been spent coordinating with the Contractor regarding contract <br />requirements, providing specification clarification, reviewing change requests, evaluating schedule issues and impacts, <br />providing additional daily on -site observation and inspections, additional construction administration, coordination and <br />attendance at additional construction meetings, coordination of claims, etc. <br />We are proposing an additional time -and -materials not -to -exceed fee of $50,977.28 to close-out the project. We are <br />also proposing an Allowance of $20,000 for contractor claim supportive services. <br />Transmitted herewith are the Fee Summary, Derivation of Fee Proposal Summary and Estimated Manhours for the <br />members of the team that were required to exceed their original limits. We greatly appreciate the opportunity to work <br />with Prescott Municipal Airport and are excited to be a part of this critical safety improvement project. If you need <br />additional information or have questions, please do not hesitate to call. <br />Sincerely, <br />Dibble En ineering <br />Steven E.
