DB Engineering was part of the construction inspection team for the Monon Trail over 38th Street project. This City of Indianapolis Department of Public Works project included the construction of a new 5 span bride, including four concrete beams and one prefabricated steel truss, new piers, and abutments, about 630 feet of retaining wall supported fill, about 1300 feet of trail, about 1100 feet of sidewalk, and other miscellaneous items. Trail traffic was maintained by a detour to allow the 38th Street work to be completed successfully.

DB Engineering developed the site utility protection plan, grading and drainage plan, and the erosion control plan for the demolition of the Old Terminal Building at the Indianapolis International Airport. The 800,000 square foot terminal building, which was replaced by the Midfield Terminal in 2008, contained four separate concourses and other structures built between 1954 and 1987. The demolition project covered more than 1,000,000 square feet overall. The project required historical research, field investigation, and close coordination with utilities and local agencies. The project was a fast-track project completed within a one-month period.

This project included the reconstruction and upgrade of an existing roundabout to an appropriately-sized, single-lane roundabout with a truck apron, resurfacing of multiple parking lots, and construction of a temporary entrance during construction. The pre-existing roundabout was not conducive to allowing delivery trucks and fire trucks with access to the Monon Center without tracking through the landscaped circle. The reconstructed roundabout is adequately-sized to allow use by designated vehicles without tracking over the curbs or through the landscaped center island. The new roundabout also included reconstructed splitter islands and trail connections as well as crossings. The pre-existing Central Park Sign remained in its previous location, which is now the center island of the new roundabout. The new roundabout has new splitter islands, modifications to the approaches, a new mountable curb at the inside edge of pavement on the circulatory roadway and a new concrete truck apron inside of the circulatory roadway. The roundabout also has new pavement markings and signage.

The DigIndy Project is a nearly 28-mile-long network of 18-foot diameter deep rock tunnels being built 250 feet beneath the city. The tunnels begin near the Indiana State Fairgrounds on the north side and end on the south side of Indianapolis. DigIndy will be the largest public works project in the City’s history.
DB Engineering is a member of both the design and inspection teams. DB Engineering has provided design services including site, utility, and sustainability components for four of the planned tunnels. In addition, DB Engineering is part of the inspection team selected for the project and maintains a full-time staff person at the Deep Rock Tunnel site. The Deep Rock Tunnel is the first tunnel phase of a 20-year Long Term Control Plan and is a 7.5-mile, 18-foot diameter tunnel approximately 250 below grade. DB Engineering is providing safety management and other inspection services for the project. All sewage stored and transported in the tunnel system is sewage that otherwise could have gone directly into our waterways. The tunnel system is a component of the federally-mandated plan to reduce raw sewage overflows into our waterways.

The I-65 Southeast Indiana Project was a project administered by the Indiana Department of Transportation to transform the existing four-lane facility into a six-lane facility to improve travel and safety conditions for motorists. The $143 million, design-build project included the modernization and major pavement reconstruction of 14 miles of I-65 between Exit 50 (US 50) in Jackson County and Exit 64 (SR 58) in Bartholomew County. DB Engineering provided the design for all of the small structures, storm water, and detention designs for this project.
DB Engineering’s design tasks included developing INDOT-approved Ready for Construction Plans for different segments of the project. The segments included coordination and QAQC, culvert replacement determination and reports, complete all hydraulic evaluations and reports, detention evaluations and reports, storm sewer evaluation and reports, all median ditches, inlets, and outlet design. These tasks were then followed by the designing of culvert, lining, detention, storm sewer plans and included all of the encompassing construction documents.

DB Engineering provided design and construction document services for the development of the Pennsy Trail Phase 3B between Post Road and German Church Road. The trail will connect to segments previously completed or in design and will ultimately connect Indianapolis to Cumberland and the City of Greenfield.
The project included a new multi-use path on a historic railroad alignment, two bridge crossings, at-grade street crossings, identity and trail traffic signs, lighting and pedestrian signalization, plantings, trailheads, and coordination with adjacent property owners. DB Engineering has been intimately involved with the Pennsy Trail over several years.

DB Engineering analyzed the east entrance to Carmel’s Central Park in an effort to improve drainage issues. DB Engineering looked at existing conditions and the original design drawings to build a hydraulic model of the site to evaluate potential solutions to the drainage problems.
Services provided included existing drainage analysis, grading design, and proposed drainage analysis. The design considerations consist of preventing road flooding, to minimize the impact to the existing road, trees and path, and to improve drainage pipe blockage techniques.
