Recently the County has received a RAMP Grant from CDOT for the construction of improvements to the WCR 49/511 34 Intersection (see attached aerial photo with project limits). This new stand-alone project will require Atkins to complete a set of associated bid documents which meet CDOT requirements. That will enable the County to bid out the intersection separately from the rest of the WCR 49 Extension Project. Public Works is anticipating this intersection project will be constructed in the summer of 2014. The additional design services to be provided by Atkins were accounted for in the RAMP Grant application. In the application these additional design services were estimated to be $80,000. The recent fee proposal received from Atkins is in the amount of$45,185. Costs related to design, ROW acquisition, and utilities relocation are to be paid for by the County as part of our cost-share matching funds required by the grant. The total cost of this intersection is estimated to be $2,200,000. The County cost-share funding portion is estimated to be $700,000. What options exist for the Board: The Board can choose to approve the attached Change Order No.2 with Atkins, or choose to delay or cancel the proposed additional design services. Recommendation to the Board: Public Works recommends approval of the Change Order No.2 with Atkins. If approved, the consultant plans to have completed bid documents for this project by April, 2014 so construction can proceed in June.
