Bridge #171 Replacement

HWC worked with White County to complete the Bridge #171 Replacement project. As part of the project, HWC completed bridge and roadway design, hydraulic analysis, waterway permitting, specifications, utility coordination, right-of-way acquisition, bidding, and construction administration services.

The existing bridge was an 82’ adjacent pre-stressed concrete box beam bridge built in 1969. The bridge had deteriorated to require a 12-ton load limit. Additionally, the roadway width was not sufficient for farm equipment, and the guardrail did not meet current standards. The new bridge included a 98’ multi-beam superstructure with integral end bents for minimized maintenance. The new bridge also included standard bridge railing, guardrail, and a 32’ wide roadway.

The project also included farm field drives for legal drain access in all four quadrants. Utilities were considered throughout the design process to minimize relocation impacts and avoid costly relocation expenses.

West Lafayette Safe Routes to Schools Infrastructure Project

Safe Routes to School Infrastructure

The Safe Routes to Schools Infrastructure project improved pedestrian access around Cumberland Elementary School and Happy Hollow Elementary School.

Cumberland Elementary School improvements include two crosswalks along Cumberland Avenue, new curb ramps and sidewalks, and solar-powered flashing school zone beacons. One crosswalk was relocated to improve its visibility to vehicular traffic leaving the school parking lot. Surface sidewalks were constructed to provide connectivity between the walkways on the campus and street.

Happy Hollow Elementary School updates include three crosswalks. These crosswalks were improved by constructing new curb ramps, crosswalk pavement markings, and solar-powered flashing school zone beacons. A crosswalk on New Salisbury Street is in the middle of a steep vertical grade, so the flashing beacons provide advanced warning and security for the students crossing at this location.
The flashing beacons used at each school are programmable to allow school personnel to adjust the timing for those days when school has a special schedule.

These improvements were recognized in an award received by the City of West Lafayette for the benefits from utilization of Safe Routes to Schools funding.

Grid Modernization

HWC provided design and construction inspection services for the $1.9 million Grid Modernization Project in the Downtown Corridor of New Albany, Indiana.

The project began with a conceptual study that evaluated past recommendations, identified three options for the one-way to two-way grid modernization, and identified three complementary projects for the downtown corridor. HWC studied options for grid corridor modernization, and the chosen option included converting Spring, Market, Elm, Pearl, and Bank streets to two-way traffic. This option manages vehicle patterns, improves access to downtown businesses, calms traffic, improves pedestrian safety, provides bike lanes, and enhances the economic vitality of downtown businesses.

The project included the modernization of 15 traffic signals through the project corridor and upgrades pavement markings and signage for two-way traffic. The identified complementary projects include downtown streetscape improvements, one-way to two-way conversions west of State Street, and a downtown pedestrian bicycle plan.

Water System Improvements

HWC provided planning, design, and construction inspection services on this water system improvement project, which included a system evaluation for a city of 3,600 citizens.

Improvements included a 500,000 gallon elevated storage tank, a pumping station upgrade, a distribution supply system upgrade (20,000 LF of 6”, 8”, & 12” mains and appurtenances), and upgrades implemented a two-zone pressure system utilizing the new elevated tank and an existing ground storage reservoir. The total construction cost was $2.1M.

Water Treatment Facility Improvements

HWC completed an SRF Preliminary Engineering Report for the City’s water treatment facility. Improvements to the capacity and replacement of antiquated equipment and processes included:

3 new 1,000 gallon per day aerators and a 3rd aerator/detention basin
Replacement treatment pumps with variable frequency drives
New 500,000 gallon ground storage tank and new high service pumping station
New filter backwash waste holding basin to eliminate the existing process of recycling backwash wastewater
New SCADA controls system for improved efficiency and reliable supply

Project Highlights:

One million gallons of additional water storage for the system
Increased capacity of the plant to 3.0 MGD
Replacement of existing high service pumps with two sets of pumps to reduce the high pressure required of the existing pumps which conveyed flow through the filters and into the system
Modifications at the treatment plant to replace antiquated equipment and allow for future expansion if necessary
HWC completed all facility evaluations, planning, design, bidding, and construction management phases
Construction cost of $4.5 million (funded by an SRF loan and an IOCRA DR II grant)
