Using Bore Planning Software to Complete Challenging Airport Fiber Optic Project

摘要

A solid reputation for thorough planning is what won Pinnacle Construction & Directional Boring, Inc. of Charleston, South Carolina, the bid on a challenging fiber optic installation job at the Charleston International Airport. In total, the team bored more than 2,500-ft (762 m) of 2x4-in (5.1x10.2 cm) for power and fiber conduit at the airport. However, the most challenging shot was the 285-ft (86.9 m) long bore that started just outside of the airport and ended in the terminal’s basement - 12-ft (3.7 m) below grade through a 20-in (50.8 cm) hole located 48-in (120.9 cm) off the floor in the baggage handling area. To hit that hole, bore planning software was used to map the bore ahead of time, GPR to confirm locations under main terminal access road, GPS to plot the course and on-the-rig software to complete the bore successfully. The team also needed to use a professional surveyor and a vacuum service company to support the crew on this unique project.
