This Change Order provides for an extension of time for completion of specific bid items which had to be delayed, due to the necessity of completing them in the required order of work after installation of the pedestrian bridge. Due to the constrained geometry of this trail project, completion of those specific bid items had to be completed after delivery and installation of the pedestrian bridge, otherwise mobilization and use of the crane and associated equipment required for placement of the bridge on the bridge abutments, would have damaged those items. Completion of those specific items prior to placement of the bridge, would have incurred additional costs for the repair of those items. The items that would have sustained damage and their approximate quantities that could not be completed until after installation of the pedestrian bridge were: • Item 14 Trail Surfacing Top Course (105 tons) • Items 18-26 (Landscaping items) • Item 36 Rail Fence (90 LF) • Item 37 Farm Fence (335 LF) • Item 38 Pedestrian Safety Rail (375 LF) • Item 41 Trail Marker (1 EA) • Item 42 Trailhead Kiosk (1 EA) • Item 50 Privacy Fence (40 LF) Jefferson County Public Works deemed that it is very beneficial to the project quality and for the Public to grant this extension of time. • Estimated net cost increase is $0.00 • Current Unit Contract Price $115,100.00 L.S., New Unit Contract Price $115,100.00 L.S. • Change in Contract Time: 9.5 additional Working Days Change proposed by Contractor PART 2 • Item 43 Interpretive Signage, L.S.
