Project Description:  In response to the requirement to reduce combined sewer overflows to the White River and increase the structural integrity of old brick sewers, the city of Anderson installed a cured-in-place pipe (CIPP) liner with the following key elements:

  • 85 million gallons per day bypass pumping system
  • 1,170 feet of 84-inch CIPP liner
  • 2,300 feet of 96-inch CIPP liner
  • 9 manhole liners

United Consulting initially reviewed various rehabilitation and reconstruction techniques and systems.  Multiple lining systems were bid and the cured-in-place pipe (CIPP) liner system was selected and installed.

Due to the disruption to the neighborhood, public outreach was conducted including public meetings and project presentations, newspaper ads, Facebook, and other media.  The public was updated weekly in regards to traffic and other impacts.

Approximate Cost:  $3.85 M

US 231 Phase III – New Road Construction

US 231 Phase III – New Road Construction

Client Indiana Department of
Transportation (INDOT),
Spencer County

Follow Us

Project Description:  US 231 Phase III Project in Spencer County is comprised of new terrain freeway totaling 4.5 miles of four-lane divided roadway with a grass median and two bridges in Spencer County.  The project includes a railroad grade separation and a diamond interchange at SR 162.  The project traverses densely wooded new terrain with large elevation changes and strip pits from past mining activities.  Four local roads were relocated to maintain the limited access feature of the new US 231 freeway.

The project required extensive coordination with the INDOT Office of Geotechnical Engineering due to possible mine subsidence, ponds, and the types of soil identified in the soil boring including coal, shale, and sandstone.  The project bisects three local service roads, a railroad, and State Road 162.  Coordination with the local agencies, Hoosier Railroad identified solutions to minimize the new alignments impacts on the community.

The location control route survey and topographic survey included full ground survey on a terrain that included over 100 feet of elevation changes, ponds, and strip mines. The new alignment traversed land with elevation changes of more than 50 feet and was previously mined.  Mining operations created unique geotechnical challenges which were coordinated as the project encountered mine spoils and created ponds.

Approximate Project Cost:  $25,500,000

Breadth of Services Provided:  Topographic Survey, Regulatory Permit Applications,  Roadway Design, Bridge Design, Complex Sign Design, and Utility Coordination

Madison County Bridge No. 123 / 600 W over White River

Madison County Bridge No. 123 / 600 W over White River

Client Madison County

Follow Us

Project Description: Madison County Bridge No. 123 carries CR 600 West over the White River in Madison County. The structure is a four-span, continuous variable depth concrete girder with simple span concrete end-spans. The rehabilitation project included a complete deck replacement and reconstruction of the end-spans with prestressed concrete I-beams making them continuous with the existing historic concrete girders.

United developed a design and construction method for this structure that allowed for the deck replacement without any temporary supports for the historic girders. The negative moment reinforcement in the deck was maintained over the girders and the new deck constructed above this reinforcement using a staged pour sequence to reduce construction loading. The design also eliminated two expansion joints by making the approach spans continuous with the main span. This eliminated on-going maintenance concerns for the County and significantly extended the useful service life of this structure. These unique design concepts saved the county in both construction cost and schedule.

Approximate Construction Cost: $1,200,000

Breadth of Services Provided: Design Survey, Roadway Design, Bridge Design, Scour Analysis, Right-of-Way Acquisition, and Environmental Coordination, and Report Preparation

Wabash County Bridge No. 645

Wabash County Bridge No. 645

Client Wabash County

Follow Us

Project Description: Rehabilitation of the existing historic timber covered bridge in North Manchester, Indiana. The construction involved temporarily supporting the bridge while members of the timber trusses were removed and replaced or repaired.  The existing members had to be inspected to determine if they could be reused or if they needed to be replaced. Replaced members had to closely match the original look of the timber bridge for historic purposes. A new timber shake roof was placed, the siding repaired and repainted, and the bridge was re-leveled to its original appearance. At completion, the bridge reopened to both pedestrian and vehicular traffic.

Steve Olsen of North Manchester Real Time Photography documented  the bridge’s rehabilitation in the following video.
