Research an example of accelerated construction and explain what procedures were used to accelerate that construction.
What will be an ideal response?
The freeway in Devore, California, had badly damaged concrete lanes.
Using accelerated construction techniques, the roadway was rebuilt in
19 days instead of the 10 months that were originally estimated. The
engineers, contractors, and laborers worked around the clock. They used
various procedures to facilitate their work, including the following:
• A moveable barrier system that provided dynamic lane reconfi guration to
minimize traffi c disruption
• A rapid-strength concrete mix that made it possible to open the road to
traffi c 12 hours after its placement
• Incentive/disincentive provisions to encourage the contractor to complete
the work on time
• A multifaceted outreach program to gain public support
• Automated information systems to update travelers with real-time work
