Title
143rd Street & LaGrange Road Intersection Improvement Supplement 2
History
On February 16, 2009, V3 Companies of Illinois was awarded a contract to provide Professional Design Engineering Services for a scope of work that had been developed by Village Staff to include ”…professional civil engineering services for the completion of the planning and design engineering for the 143rd Street and LaGrange Road Intersection Improvement Project” in the amount of $280,300. Included in this original scope of services document provided by V3 dated February 4, 2009, were services envisioned to be required to update and finalize a 90% complete plan set that had previously been developed and approved by the Village and submitted to IDOT. The update, as requested by the Village and proposed by V3, was to include the addition of an expanded project totaling 4800 linear feet (added 2100 linear feet to the original project length to accommodate Village needs at 142nd Street and provide better traffic management during construction). Additionally, added to the revised scope of services were such elements as dual left turn lanes in all directions, traffic signal improvements (142nd Street and LaGrange Road, and 143rd Street and Ravinia), basic improved medians within the two roadways and plans for relocating a watermain within the expanded project limits.
Since the awarding of the original contract, a Supplement to provide Professional Surveying Services was approved by the Board on July 20, 2009, adding $34,200 to the existing contract. Since July 2009, V3 has responded to the numerous requests for services requested by the Village as the Intersection Improvement Project has continued to evolve. V3 has represented the Village at project coordination and review meetings with IDOT, has attended and coordinated regularly scheduled stakeholder meetings with Village staff and affected utilities, and has supplied modifications to the design documents submitted to IDOT as required following multiple IDOT design review comments.
V3, as a part of the services provided within the existing contract, has provided high-level right-of-way requirements for the proposed improvements based upon the Village’s vision and the requirements set forth by IDOT. When it became clear that elements of the IDOT requirements were adding significant additional cost to the project due to the right of way that would be required to meet the criteria set forth by IDOT, the Village directed V3 to provide a modified plan set that removed elements that were originally submitted to IDOT for approval. The removal of the elements (dedicated right-turn lanes) reduced significantly the amount and number of property acquisitions that would be required to build the final improvement and simplified the traffic signal control work that would have to be undertaken to add traffic control signals to the project as a whole.
During the internal Village review process, the Village directed that the overhead utilities that exist within the project limits be relocated underground as the Village wished to present an aesthetically pleasing improvement for this project. It was not anticipated during the initial discussions for the design work nor during the course of discussion for the first Supplement, that the overhead utilities would be relocated underground. As the effort required to move overhead utilities underground is very significant, these added costs have been included in Supplement 2.
As property acquisition for the planned roadway improvements, the watermain relocation project, the overhead utility relocation project became more finitely identified, plats and legal descriptions were prepared for use by Counsel to facilitate the property acquisition efforts. This effort was not originally anticipated.
Also, as the project evolved, the Village was in the process of finalizing a Master Plan for the LaGrange Road Corridor and the streets that intersect with it. Included in that Master Plan are elements that provide multiple forms of mobility and build upon a “Complete Street” concept wherein vehicular and mass transportation, as well as pedestrian and bicycle mobility requirements are designed integral to the project. The “Complete Street” concept also includes the aesthetic elements that the Village has adopted as a part of the corridor Master Plan and will include intersection enhancements and color treatments and plantings.
