BCE provided design services for temporary structures on this
project. This included sheetpile embankment retaining walls and cofferdams. The
work bridge was designed to carry 100 ton truck cranes for everyday use and 375 ton
crawler cranes for Drilled Shaft construction. The work bridge is required for year
round use including bridge demolition and prestressed girder erection, this required
careful analysis of outrigger loading and track pressure concentrations on the crawler
cranes. Auxiliary piers were required for access to the drilled shafts and these piers
were configured to resist significant additional loading from drilling and casing
removal. BCE was responsible for the complete bridge design including the braced
pile bents. This work bridge is currently being used in phase II construction and
was used for the entire phase I construction period. (click   here   for more pics) |

BCE provided the structural design for this 300' long conveyor along
with numerous other conventional conveyors. A tapered truss consisting of single
angle web members and structural tee chords supports the stacker conveyor. The bracing
for the main tower is configured with a moment framed opening to allow passage of
the truss, large horizontal thrusts from belt pull and seismic forces are resisted
at an A-Frame on the lower end. The "cable" stays are 8" dia. Pipes with strake
plates. The response spectrum method was used for seismic design. (click   here   for more pics) |
