BPA was responsible for the fast-tract development of final contract documents for FDOT’s widening of this 3016’ long concrete segmental box girder viaduct under a subconsultant agreement. The work consisted of adding 3’-8” to each side of the box girder concrete deck slab, adding bottom longitudinal post-tensioning in 9 spans, and re-striping the bridge for two lanes of traffic. Plans were completed in three months and bid results were within 1% of the engineer’s estimate.
