Title
156th Street - Ravinia Avenue to LaGrange Road - Design Engineering
History
At the October 3, 2011 Board meeting, the Board authorized the Village Manager to finalize and execute a supplemental agreement with HR Green, Inc. (formerly Smith Engineering Consultants, Inc.) (Green), in the amount of $29,995. The supplement provided for additional professional design engineering services required by IDOT to update and finalize the 156th Street plans to provide updated roadway profiles and drainage details to match the LaGrange Road widening plans. The updated 156th Street plans, which require IDOT approval regarding the intersection at LaGrange Road, will provide plans, specifications and estimates permitting the Village to advertise, award and construct 156th Street from LaGrange Road to Ravinia Avenue during 2012.
During Green’s work to finalize plans, IDOT advised Green of an additional requirement that updated 2012 traffic counts (previous counts were from 2004) be used in the new Intersection Design Study (IDS) being prepared by Green. Green asked staff to inquire of IDOT the necessity for an updated count, and IDOT thereafter confirmed the need for new counts. Green has provided a scope and fee proposal for this added effort. Staff has reviewed their January 18, 2012, proposal and finds it to be reasonable and customary for such work.
It is Staff’s recommendation that the January 18, 2012, proposal, in the amount of $1,650, and identified as Amendment Number 1 be accepted to permit Green to complete their 156th Street Design Engineering work.
On February 20, 2012, this item was reviewed and approved by the Public Works and Engineering Committee and referred to the Board for approval.
