Highway 91/17 Upgrades Design-Build
Scope of Work
The project’s scope of work included complex detours, utility relocation, drainage installation, pre-loading of soft soils, lightweight fills, concrete bridge structures, stone columns, drilled shafts, electrical, and all associated roadworks construction. The project, also in close proximity to Burns Bog, required special management and attention to protect environmental and cultural resource values of this complex ecosystem.
Challenges
Traffic management and temporary detour design was a key component to the success of the team’s execution strategy, this included:
- Complex traffic management challenges and careful consideration of staging requirements; multiple project stakeholders requiring coordination of work and effective communication of construction progress.
- Busy intersection upgrade construction while maintaining existing traffic flows and access to multiple businesses and residences.
