I. Entitlement Analysis The purpose of this Change Order is to provide means to compensate the Contractor to construct a new signalized intersection on 66th Avenue at 53rd Street. This scope of work was not included at time of original bid. II. Time Analysis The Contractor is not pursuing a time extension to complete this additional work. III. Engineer's Estimate a. Basis of Estimate The Engineer's Estimate was based on current State-Wide-Average (SWA) multiplied by the Engineer-of-Records' plan quantities for this new scope of work. Considering the increase in unit cost is appropriate as the decision to proceed with this extra work occurred at this time and the Contractor was unable to proceed with procurement of the necessary components earlier. To this we added Mobilization & Maintenance of Traffic(MOT)as a percentage based on original contract. This resulted in an Engineer's Estimate totaling $827,689.97. b. Estimate The Engineer's Estimate to add a signalized intersection at 53rd Street resulted in the net increase to Contract in the amount of $827,689.97. This price includes all mark-ups and no bonding. Refer to Appendix"A"for a breakdown of the Engineer's Estimate and backup documentation. c. Contractor's Quote The Contractor's quote submitted a Change Order in the amount of Eight Hundred Fourteen Thousand Two Hundred Seventy-Seven and Fourteen Cents ($814,277.14).
