Abstract
The Route 1&9T/New Road project is a three-part program to relieve the notoriously congested Route 1&9 (Tonelle Avenue) in the heart of the industrial sector of Jersey City, New Jersey. Contract 1 consisted of constructing a new road over a 1 mi (1.6 km) Long stretch of unimproved land serving as part of the parking lot to a large postal facility. To get to grade, modular gravity retaining walls were specified on either side of the 54 ft (16.5 m) wide roadway corridor. While the proposed wall heights ranged from only 2-8 ft (0.6-2.4 m), the soils present on-site were not even suitable for a shallow embankment. The underlying soils were mixed fills and organic peat, underlain by soft clay and silt to depths ofupto 75 ft (23 m). The proposed solution presented in the project plans certainly would have worked on paper; however, Menard, having had poor experiences with rigid inclusion installation and load transfer platform (LTP) compaction at or just above the groundwater table, recognized the potential difficulties, delays and rework that would likely be required during construction of what was shown on the contract plans. As such, it proposed a value-engineered solution that resulted in a vast improvement in the constructability, performance and overall cost of the system. However, the benefits of this solution were not appreciated by the owner and the solution was met with high levels of scrutiny, perhaps because it differed from what was shown on the contract plans. The level of testing required of the solution was far greater than what was required of the design shown on the contract plans. Such rigorous and unwarranted confirmation of a valueengineered solution consumed time, money and resources that could be better used elsewhere. Instead, these designs should be compared to the design in the original contract plans based on technical merit and expected long-term behavior. This article walks through the design and construction process for the value-engineered solution and highlights the many challenges experienced by the contractor to get final approval of the work perormed. Though the COVID-19 Pandemic was an unanticipated complication, the perceived distrust of the contractor's proposals and work was a barrier to progress that the authors hope will not exist in the future.
