Transportation Market Projects
SUE Engineering Services
NTH provided the design-build team with data on the existing subsurface utilities to design and build the Mound Road project - one of the most important corridors in Southeast Michigan. Innovate Mound is more than a reconstruction project. It is a re-envisioning of the corridor to include improvements to the roadway, pedestrian facilities, and smart technologies for emerging mobility features. This project will serve the long-term needs of local businesses and citizens alike.
Detroit People Mover
Structural Inspection and Repair
The Detroit People Mover is an automated light-rail transit system using an elevated guideway with a continuous loop route configuration. The superstructure of the guideway consists of precast, post tensioned, concrete segmental box beams supported on a substructure of conventionally reinforced and post tensioned reinforced concrete columns.
NTH conducted a guideway inspection to ascertain the current structural condition of the guideway and its components and is currently coordinating maintenance repair work providing construction contract administration and quality control services.
City of Warren Streets, Sidewalks & Water Mains
Our long-term history with the City of Warren, and the mutual level of trust we have developed, allowed us to implement a program to provide full time construction observation services for critical operations and less than full time for operations for project demands having less potential risk, thus saving the overall costs to the city. NTH maintained open channels of communication with the city to head off construction related issues and to offer timely solutions to keep projects on track. Our experience and quick turn-around for unexpected conditions has reduced contractor claims for lost time.
Gordie Howe International Bridge
This design build project is being constructed by the Bridging North America (BNA) team for the Windsor Detroit Building Authority. NTH has been involved since the early concepts of the project. Now, as Engineer of Record for geotechnical aspects, NTH is providing construction phase services to ensure that the project is constructed as designed and meets WDBA’s requirements and expectations.
Wayne County Bridges and Rehabilitation
Geotechnical Investigations & Foundation Analysis And Design
Wayne County is going through a major program to upgrade and / or replace aging existing bridges to meet bridge safety requirements. NTH has worked as a subconsultant to Michael Baker International to evaluate subsurface conditions at the locations of the referenced bridges. For each of these projects, prior to moving into final design, a well planned and executed geotechnical investigation was required to determine the prevailing ground conditions and evaluate requirements for replacement bridge elements and approach pavement sections. NTH provided recommendations consistent with Michael Baker's design methodologies.
Ann Arbor WWTP Bridge Replacement
The goal of the project is to able to safely access the city’s Wastewater Treatment Plant (WWTP) from Access Road. The current crossing of the Huron River for Access Road is a two-span bridge that was constructed in 1934. NTH is providing the design and construction of a new bridge over the Huron River to parallel the existing 90-year old, 2 span, reinforced concrete deck on rolled steel beams bridge. The new design will look at a new, 2-lane structure and possible combination of a new 1-lane bridge to work in conjunction with the existing bridge which has 3 larger sewers located on the bridge and must remain in service.
