Sanchez, P.E Page 2 Williams Island VehicularlPedestrian Bridge, Miami.Dade County, Florida This is a VehicularlPedestrian Bridge connecting the two main Islands. The structure consists of AASHTO Beams with a cast-in-place deck and a canopy. Mr. Sanchez was the Project Engineer and designer of the substructure. Pedestrian Bridge over 1.95 at NW 65 Street, Miami.Dade County, Florida The structure is composed of two continuous single steel box girder spans over Interstate 1-95 and cast in place approach spans. Mr. Sanchez was the designer of the steel box girder and he also participated in the design of the substructure. S.R. 934 (Hialeah Expressway) - Miami.Dade County, Florida .FDOT District VI (Steel Plate Girders) Bridge Development Report (BDR), 30 % Bridge Plans and Final Plans This project consisted of the widening of the simple supported steel plate girders bridges (slightly curved and on tangent with six spans each @ 125') at S.R. 934 Over the FEC Railroad Crossing at W. 5th Way and the replacement of the existing S.R. 934 Bridge Over the Miami Canal & S.R. 25 with simple and continuous steel plate girders straight spans. Mr. Sanchez was in charge of the BDR and his final design activities were the following: a. Retrofit design and checking of the existing Integral Steel Pier Caps at S.R. 934 Over the FEC Railroad Crossing at W. 5th Way. Vertical clearance constrains and the higher loads over the existing steel frame require strengthening of the steel pier-cap and the foundation. The steel pier-cap is strengthened using external post-tensioning to increase the positive moment capacity. Also he performed the Quality Control of the design for the new steel plate girders. b. Quality Assurance Review of all the structural plans for the new structure at S.R. 934 Over the Miami Canal & S.R. 25. S.R. 826 (Palmetto Expressway) Section 2 - FOOT District VI (Steel Box Girders and Plate girders Curved and Straight) and Pedestrian Bridge Over S.R. 826 - Bridge Development Report (BDR), 30 % Bridge Plans and Final Plans This project has six steel box girders and four steel plate girders bridges (4,312 linear feet of steel box girders and steel plate girders with continuous and simply supported spans, maximum span of 262'-6", curved and on tangent) with four (4) Integral Steel Pier Caps. This project is 100 % completed and ready to be submitted for final review. Mr. Sanchez was in charge of the BDR and his final design activities were the following: a. Design and Plans Supervision. b. Supervised the use of the BSDI Program for the curved one lane steel box girders Bridge No.3 (Two Units: Unit NO.1 = 709' and Unit NO.2 = 790', maximum span 229'). The BSDI Program is a 3 dimensional, finite element program that accounts for all major stresses including torsion and warping. c. Performed Load Rating of several structures by the LRFR Method. This project was designed by the LFD Method but the Department requested to perform the rating by the LRFR Method. d. Quality Assurance Review of all the design & structural plans with the help of the Project Engineer. Westbound Gandy Bridge, Pinellas/Hillsborough County, FL - FOOT District VII (Segmental Bulb-Tee with Drop.ln-Beams longitudinally post-tensioned) This high level fixed bridge over the ICWW in Tampa is 14,000 feet long. The navigable main unit consists of three continuous spans 144'-234. 5'-144' of five segmental bulb-T girders with special haunched sections at the supports. The approach spans consisted of two alternates, Florida bulb-T and AASHTO Types IV and VI beams, with the bulb-T option selected based on low bid. The bridge is founded on drilled shafts designed to sustain ship impact forces of 2,400 kips. Mr. Sanchez supervised the design of the navigable main unit superstructure including Quality Assurance Review of the design and plans. Also, he performed a Quality Assurance Design Review of the substructure subjected to ship impact.
