• All survey and layout requirements
• Spoil control and disposal
• Furnish and install all rebar cages, including the addition of CSL tubes
• Furnish and place all concrete
• CSL testing and grouting of CSL tubes

• Monitoring and protection of all erosion and sediment control items

Work was performed near an active railroad line; therefore, all crew members received RR Protective Training.
