Featured Projects

HEI was selected by the Village of Rantoul to provide Phase I, II, and III services for this $6.7M DCEO RDMS funded downtown reconstruction/streetscape project. The project consisted of reconstructing 7 blocks of street and construction of a plaza/event area in the downtown business district. The improvements included new PCC pavement, HMA resurfacing, curb & gutter, storm sewer, water system including water mains, hydrants, and service connections, sanitary sewer system including mains, manholes, and lateral connections, ADA compliant PCC decorative sidewalk including colored, stamped concrete, decorative pedestrian and street lighting, streetscape elements including bicycle racks, benches, planters, and landscaping, entertainment stage with canopy, and decorative seat walls. Raised business entrances created a challenge meeting ADA compliancy requiring ramps and railings to meet the grade changes. The water system work included 3,000’ of water main, 25 valves, 3,200’ of water service connections, water main casings, and 6 fire hydrants. The sanitary sewer system work included 1,250’ of sanitary sewer main, 12 manholes, 1,650’ of service connections, and abandon and fill 700’ of existing sanitary sewer. HEI provided design services including survey, IDOT coordination, IEPA coordination, environmental coordination, utility coordination, public involvement including two public meetings and individual meetings with property owners, traffic analysis and intersection design study, roadway design, storm sewer design, water system design, sanitary sewer system design, sidewalk design including detailed ADA compliancy plan, streetscape design, and final plans, specifications, and estimates for a state letting. HEI provided a Resident Engineer and construction inspectors to complete construction management services for the water and sanitary system replacements including property owner coordination, daily diary and weekly reports, quantity and material documentation, traffic control inspections, erosion control inspections, HMA and aggregate nuclear density testing, field concrete testing, development of change orders, development of pay estimates, development of punchlist, and final project closeout.

HEI provided preliminary and construction engineering services for this $4M DCEO RDMS funded downtown square reconstruction/ streetscape project. The project included the four quadrants in the square, one block in all four directions from the square on Main Street and Broadway Street, and Market Alley which is a pedestrian alley used for outdoor dining and special events. The project included reconstructing the historical square to improve traffic flow, maximize parking, improve pedestrian safety, and create on-street dining. The project included ADA compliant sidewalks, brick pavers, decorative railing, curb and gutter, storm sewer, resurfaced pavements, signing, street lighting, historic pedestrian scale lighting, and streetscape amenities. HEI provided preliminary engineering services including a survey, traffic study, intersection design study, geometric option development, IDOT and FHWA coordination, environmental coordination, historic building coordination, streetscape element option development, utility coordination, streetscape design, and plans, specifications and estimates for a local letting. HEI provided construction engineering services including daily diary, construction inspection of contractor operations, quantity documentation, materials inspection and testing, development of pay estimates, development of change orders, and project closeout. The project faced obstacles due to the city’s desire to widen sidewalks for on-street dining while preserving the number of parking spaces and eliminating steps into buildings. HEI successfully created an ADA compliance plan that ensured accessibility throughout the square while maintaining parking spaces and expanding sidewalk widths for outdoor dining. Significant coordination was required between the city, contractor, and business owners. HEI led the daily coordination with business owners throughout construction to minimize the disruption to the downtown businesses.

HEI was selected by the City of Mt. Sterling to provide preliminary engineering services to assist with developing an ITEP grant application and Phase I, II, and III engineering for the reconstruction of Main Street (US 24) in the historic downtown area.

HEI provided Phase I, Phase II and Phase III for the reconstruction of the existing one-way coupled streets in downtown Jacksonville, IL.
