Peralte-Clark performed Phase I and Phase II design of roadway widening and reconstruction for 1.5 miles of Arlington Heights Road between Lake-Cook Road and north of IL Route 83 in Lake County, Illinois. The project includes traffic analysis at the intersections with Lake-Cook Road, Checker Road and Illinois Route 83 to determine safety and mobility improvements, crash analysis, development of alternatives for mainline geometry, Phase I preliminary and environmental engineering services, and public involvement activities. Due to the COVID-19 global pandemic, a Virtual Public Forum was developed where the general public were able to access project presentation materials and the public comment forms and interactive map via the project website. Peralte-Clark worked directly with members of the GIS department at LCDOT to develop an interactive map and public comment system to gather feedback from the public their issues and concerns related to the project corridor. The Virtual Public Forum was held for four weeks and received over 2,500 “hits” to the project website as well as over 140 written comments and 315 “likes” of comments posted.

Peralte-Clark performed Phase II design of intersection widening, new traffic signals and resurfacing. The scope included the installation of new traffic signals at the US 30 and IL 50 intersection, traffic signal modifications at the intersections of US 30 and Matteson Avenue, US 30 and Lindenwood Drive and IL 50 and Gateway Drive, improved channelization, and improved bicyclist and pedestrian access. Drainage and lighting design to accommodate the proposed improvement were part of the scope. Peralte-Clark prepared the Phase II design plans in 3D for this project. Deliverables included traditional cross sections in addition to the development of a roadway model. This is one of the first projects to be completed within 3D for IDOT District One.

Peralte-Clark is a leader in 3D Modeling using Bentley’s Open Roads Designer and has facilitated discussions within the industry on IDOT’s rollout of the new Open Roads workspace and 3D modeling policies and criteria. Peralte-Clark continues to lead the charge in 3D modeling by serving as an expert resource on the ACEC/Tollway/IRTBA 3D CIM/BIM Committee.

This project is in the heart of the Bronzeville neighborhood and is slated for robust revitalization efforts as part of the City’s INVEST South/West initiative and to model the vibrant cultural core of the Quad Communities. The Peralte-Clark team is working with CDOT and the community to foster authentic change and revival through infrastructure improvements and public art/placemaking initiatives.
The Quad Communities/Bronzeville Cottage Grove Corridor Improvements span a total of 2 miles of Chicago streets and are concentrated along three major corridors:

·  47th Street, Prairie Avenue to Cottage Grove Avenue
·  43rd Street, Prairie Avenue to Cottage Grove Avenue
·  Cottage Grove, 42nd Street to 47th Place

The goal of the project is to provide a safe, walkable, and attractive street that will foster community and economic growth. As a neighborhood core, the project area is a focal point for pedestrian activity, shopping, public spaces and quality of life amenities for local residents. Through the concept design process, the streetscape will seek to improve safety and connectivity, as well as pay tribute to the Bronzeville history through artistic representation within the public space.

Due to COVID-19, an on-line forum was utilized as the community meeting platform to solicit information to advance the design concepts. Live polling was conducted during the presentation for input from the community residents regarding corridor concepts, improvement location and timing, branding, corridor concerns and features, priorities, issues, and character. Links to the project website and survey were provided seeking more in-depth community input.

This Phase I project includes both design and programming work for ADA ramp designs throughout IDOT District One under a Task Order Contract. The contract includes Phase I programming work for approximately 500 ramp locations and Phase II design work for 393 ramp locations. The scope includes coordination with IDOT and the Federal Highway Administration (FHWA) for MEPs, review of previously designed Phase I ramps and PS&E preparation for the Phase II plans. The team is also tasked to prepare updated training and safety videos for IDOT staff as part of this contract.

Part of Illinois Department of Transportation’s (IDOT) mission is to provide innovative, sustainable, and multimodal transportation solutions as well as make Illinois’ transportation systems accessible to all. IDOT allocates resources to achieve accessibility on pedestrian access routes with improvements to curb ramps, sidewalks, and crosswalks within its public rights-of-way. IDOT implemented a timeframe of approximately twenty-five years to make all facilities compliant to the maximum extent feasible.

Peralte-Clark prepared a Phase I Project Report and Phase II Contract Plans for traffic signal modifications plans for the existing signalized intersections of Orchard Road at Rochester Drive, Orchard Road at Aucutt Road, and Fabyan Parkway at IL 31 in Kane County. Project safety improvements included the design of new flashing left arrow phasing for left turn signals at Orchard/Rochester and Orchard/Aucutt and installation of wet reflective pavement markings on Orchard Road between US 30 and Jericho Road. The project also included the design of a dilemma zone detection system at Fabyan Parkway at IL 31 and advance warning flashers and signage on the Fabyan Parkway Bridge over the Fox River.

The Highway Safety Improvement Program (HSIP) is a federal program where funds are set aside for projects that achieve a significant reduction in fatalities and serious injuries on all public roads and increase the safety of the roadway and its roadway users. Strong consideration is given to specific safety that offer significant benefit to reduction of severe crashes.

Peralte-Clark is performing construction observation services for the replacement of the northbound and southbound Mile-Long Bridge on Interstate I-294 for the Illinois Tollway. The scope of work includes the reconstruction and realignment of existing main line pavement and reconstruction of all main line shoulders. The Peralte-Clark inspection team is reviewing plans and documents, inspecting and documenting existing main line elements, guardrails, pavement, and barrier wall prior to the start of construction, performing tree removal contractor observation, mainline bridge construction observation, maintenance of traffic placement observation, pipe jacking observation and a variety of other inspection and construction documentation tasks. The two-mile-long bridge structures are anticipated to be fully replaced within four construction seasons. This project is part of a larger program to fully reconstruct and widen the I-294 corridor from 95th Street to Balmoral Avenue, a distance of 40 miles at a cost of approximately $5 billion dollars.

Peralte-Clark performed Phase II design for its prime contract for the preparation of advanced shoulder rehabilitation, temporary lighting and MOT plans, specifications and estimates for four mainline counterflow crossovers as part of the reconstruction of the I-294 Central Tri-State Corridor for the Illinois Tollway. The project scope of work included MOT to rehabilitate existing shoulders and crossover locations in anticipation of future I-294 mainline contracts. A key component was the coordination efforts with mainline contracts I-17-4300 and I-17-4301 as well as the Tollway DCM, Tollway staff and the project team formulating workplans and workflows to keep this accelerated project on schedule.

Peralte-Clark led the preparation of advanced rehabilitation plans as an “enabling project” to the overall I-294 Central Tri-State reconstruction program.  This project is part of a larger program to fully reconstruct and expand the I-294 Central Tri-State Corridor, a $5 billion-dollar program.
