This change order will be to the existing Shaw Construction Guaranteed Maximum Price contract for the utilities work approved by Council via Resolution 15-2019 on February 11, 2019. The rationale for the request is due to unforeseen underground conditions in the road base and a desire to repair the base prior to the summer tourist season. Change Orders: 1)Sub excavation & Imported Fill –Rio Grande Pl. Background:During excavation for the deep utilities, site observations by the Geotechnical Engineer of Record on 4/23/19 identified unforeseen unsuitable soils at varying depths that could potentially impact the performance and longevity of the new street surface. The recommended action of the engineer is sub excavation of the poor soils beneath the new road surface to a depth of approximately 2 ft and import of a Class 6 road base to ensure a suitable base for the new road. Cost Impacts:The cost impact of the additional excavation and imported fill is $379,298.53 This change order involves work beyond the scope of the utility replacement project and beyond the purpose of the utility funds. As such, staff is proposing to track these costs separately under a new project number. If City Council approves this resolution, it will be requested that City Council appropriate funds from the Asset Management Plan Fund balance during the second reading of the spring budget supplemental on May 13, 2019. RECOMMENDED ACTION:Staff recommends that council approve Shaw Project Change Order #010 and transfer of the change order to a new project number. The recommendation reduces community impact by addressing the condition while the site is already under construction and closed to public access. 2 Page 2 of 2 ALTERNATIVES: The City could forgo this work and only repair the area disturbed by the current excavation. With this alternative, it is likely the City will experience road base deterioration accelerated as a faster pace through failing pavement and sidewalks.
