Florida International University pedestrian bridge collapse - wikipedia Florida International University pedestrian bridge collapse The FIU Pedestrian Bridge Collapse National Transportation Safety Board members inspecting the collapsed pedestrian bridge on March 16 Date March 15, 2018 ( 2018 - 03 - 15 ) Time 1 : 47 p.m. EDT Location University Park and Sweetwater, Florida, U.S. Type Bridge collapse Deaths 6 Non-fatal injuries 9 ( Full screen ) On March 15, 2018, a 175 - foot - long ( 53 m ), recently - erected section of the FIU Sweetwater UniversityCity pedestrian bridge collapsed onto the Tamiami Trail ( U.S. Route 41 ). The initial construction on the pedestrian bridge was located in front of the campus of Florida International University ( FIU ) in University Park, a suburb west of Miami, Florida, United States, and was in the process of post-tension rod adjustment when it suddenly failed. The road beneath it had been opened to traffic. Several occupied vehicles were crushed underneath, which resulted in six deaths and nine injuries.

It was intended to improve pedestrian safety, as the busy crosswalks at this wide, busy intersection had been identified as a safety hazard and the site of fatal collisions. The $14.2 million project was funded with a $19.4 million Transportation Investment Generating Economic Recovery ( TIGER ) grant from the United States Department of Transportation in 2013, along with state agencies. The bridge itself cost $9 million to construct. The main companies behind the construction project are Munilla Construction Management ( MCM ), a Miami - based construction management firm, and FIGG Bridge Engineers, a Tallahassee - based firm. Unlike most bridges in Florida, the design for this project was overseen by the university itself, not the Florida Department of Transportation. Florida International University is known for its expertise in accelerated bridge construction, and has attracted international scholars as PhD students. It is home to the federally - funded Accelerated Bridge Construction University Transportation Center, which sponsors industry conferences and seminars. Bridge layout Elevation Engineering Drawing of Proposed FIU Sweetwater Pedestrian Bridge The full 320 - foot - long ( 98 m ) pedestrian bridge was to cross both a major roadway and a parallel water canal with two separate spans connected at a faux cable - stay tower. The main, roadway - crossing span was 175 ft long, the shorter canal span was to be 99 ft long. An elevator and stairs at the south end added 31 ft, and at the north end, 15 feet, for a total bridge length of 320 feet. At the bridge site, the Tamiami Trail roadway has six lanes of traffic plus two turn lanes. The main span was rolled into place and set on support columns on March 10, five days before the collapse. The canal span, access ramps, and faux cable - stay tower had not yet been built. Pedestrian use was to begin when the whole project was complete. The school was on spring break at the time of collapse. The section of the bridge that collapsed weighed 950 short tons ( 860 metric tons ) and fell onto several vehicles on the roadway below. Bridge construction and design Construction of the bridge began in March 2016 and was scheduled to be completed in December 2018. The bridge 's main span was assembled adjacent to the highway using accelerated bridge construction ( ABC ), a technique promoted at the university. It was lifted into place on the morning of March 10, five days before the collapse, during a weekend closure of the highway.

The bridge was a post-tensioned concrete structure. Concrete structures are generally 10 times heavier than equivalent steel designs. The bridge was made using a new formulation for concrete intended to stay cleaner than standard concrete formulations.In the main bridge span, the concrete floor deck, roof, and diagonal struts each contained post-tensioning cables whose compressive effect on the concrete could be adjusted after the concrete was cured. Adjustments were expected each time the span was moved onto a different foundation with different support points. The full bridge project was styled to look like a cable - stayed bridge with pylon tower and high cables for dramatic effect. But functionally and structurally it was actually a truss bridge, with the spans being fully self - supporting. The bridge spans used a novel concrete truss design invented for this project, a `` re-invented I - beam concept ''. Concrete truss bridges are rarely constructed, and few exist. The vertical web of the beam was a series of triangulated concrete diagonal struts along the centerline, and the diagonal angles of the struts varied across the bridge so they would align with pipes from the center pylon, in the eventual faux cable - stayed appearance. A specification change late in the project required moving the bridge 's main pylon tower 11 feet ( 3 meters ) north to allow for future highway widening, increasing the gap between the bridge end supports and requiring some new structural design. The concrete walkway deck was to act as the horizontal bottom flange of a wide I - beam, and the concrete roof canopy was to function as the horizontal top flange of the I - beam. The walkway was thus nearer to ground level than in a standard design where the walkway is placed on top of the structural support system. This reduced the number of steps to climb. The deck carries the entire weight of the bridge span, as a tension load. The canopy carries the structure 's main compressive loads. The diagonal struts carry either compression or tension forces, depending on their angle and position. The struts contain post-tensioning rods that connect the flanges, and are adjusted as needed. VSL was the company contracted for the post tensioning ( PT ) of the new bridge. Post-tensioning of a diagonal member may be one of the reasons for the structural failure of the FIU bridge. Concrete is much more prone to crack than steel in trusses. Certain cracks could compromise the cable / rod anchorings, making failure inevitable when the post-tensioning operation began. The bridge was meant to last more than 100 years, and to withstand a Category 5 hurricane, according to a statement by the university. Collapse Schematic of the bridge. Green : collapsed parts, Blue : not installed at the time of the collapse. The diagonal beam that was undergoing post-tension cable / rod adjustment at the time of the collapse is highlighted in red. Reports of cracking On March 13, the third day after lifting of the main span, the project 's lead engineer discovered cracks at the north end of the span ( the end that later broke ). He reported this by voicemail to a Florida Department of Transportation ( FDOT ) employee. He thought this was not an immediate safety issue, merely something that would need to be repaired later. The FDOT recipient was away for several days and did not hear this message until the day after the collapse. At 9 a.m. on March 15, a university employee heard a loud `` whip cracking '' sound while under the bridge span, waiting for a red traffic light. At the same time, the design - build team met for about two hours at the construction site to discuss the cracks discovered on March 13. Representatives from both FIU and the FDOT were present. The FIGG lead engineer 's conclusions were that the structural integrity of the bridge was not compromised and that there were no safety concerns raised by the presence of the crack. The mayor of Miami - Dade County, Carlos A. Giménez, said that workers conducted a stress test on the morning of March 15. Collapse At 1 : 47 p.m., the north end of the installed bridge span sagged deeply as the first diagonal fractured, folded, and immediately dropped the heavy full span onto the roadway below. A surveillance video shows the collapse sequence took only a few video frames. United States Senator and FIU adjunct professor Marco Rubio tweeted that engineers were tightening loosened cables on March 15 : Workers were adding more tension to the steel rod ( tendon ) inside a concrete diagonal strut at the north end. The National Transportation Safety Board, who are investigating the collapse, stated that crews were applying `` post-tensioning force '' on the bridge before the collapse. The tensioning rod that was being tightened at the time of the collapse, with a hydraulic tensioning machine ( blue ) still attached to its end, extends from the canopy in the upper left of this image. At this time, it is not clear why the post-tensioning operation by VSL company was being carried out at the time of the collapse as the bridge diagonal member support they were working on would have already been in compression. The bottom joint of diagonal member # 11 ( which contains the anchor nut for the post-tensioning rod ) apparently failed explosively, during the post-tensioning operation, causing the bridge to collapse. Currently, it remains unknown why the joint may have failed, although post-tensioning remains a possible contributor. The span that collapsed weighed 950 short tons ( 861 tonnes ). At the time of the collapse, the roadway was open and there were multiple cars stopped at a traffic light under the span. A driver who survived the collapse reported small rocks fell onto her car just before the car got smashed. A worker saved himself when he heard cracking and locked his safety harness just before the collapse. Eight cars were reported to have been crushed. Six people were killed and nine others were injured ; while early reports said that the death toll was expected to rise, authorities said on March 18 that all bodies had been accounted for. Five of the victims were killed immediately when the bridge fell ; one died at the hospital. An employee of VSL, Navaro Brown, 37, worked for the company contracted to apply post-tensioning and died in the collapse. Two other employees of the company were hospitalized. The other deceased victims of the tragedy were identified as Alberto Arias, 53, Brandon Brownfield, 39, FIU student Alexa Duran, 18, Rolando Fraga, 60, and Oswaldo Gonzalez, 57. Aftermath On March 16, the Florida Highway Patrol announced Southwest 8th Street between Southwest 107th and 117th Avenues and the eastbound Southwest 8th Street exit from the Homestead Extension of Florida 's Turnpike would be closed indefinitely while debris removal and investigations were conducted. Debris from the bridge was cleared by March 24, allowing Southwest 8th Street to be reopened. A team of 15 people from the National Transportation Safety Board ( NTSB ) began their investigation on the morning of March 16. On March 19, 2018 the first civil lawsuit was filed against Figg Bridge Engineers, MCM, Bolton Perez & Associates, the project 's consulting engineer, Louis Berger, and Network Engineering Services for reckless negligence. Inquiry Members of the NTSB 's Go Team for the investigation boarding an FAA plane to travel to Miami. On March 15, 2018 the National Transportation Safety Board ( NTSB ) launched a Go - team to investigate the bridge collapse incident. The accident number assigned is HWY18MH009. On March 16, 2018 the NTSB Investigators held their first press conference to discuss the inquiry into the bridge collapse. Noteworthy points from the meeting included a statement that the inquiry was in the very early stages, that cracks in the bridge superstructure did not necessarily make the bridge unsafe, that on - site investigations would take about a week, that preserving perishable evidence was crucial, and that bridge workers were applying a `` post-tensioning force '' on the bridge before the failure. On March 21, 2018 the NTSB sent out the following press release : Investigators secured a contract Tuesday to have a company remove components from the bridge that we believe warrant additional examination and testing. These components include sections of the floor, the canopy, a vertical member and a diagonal member ; all from the north end of the structure. These components were in the area of where the failure occurred. In addition to these components, we obtained additional core samples from this area to supplement the core samples we obtained earlier. Shipping the core samples along with some recovered rebar and tensioning rods to the Turner Fairbank Highway Research Center, in McLean, Virginia, for testing and evaluation. The investigative team has obtained an exemplar tensioning rod and hydraulic unit used by the construction crew to make tension adjustments to the tensioning rods. These items are also being shipped to the Turner Fairbank Highway Research Center for evaluation and testing. The larger bridge components the investigative team is removing, are being stored at a secured Florida Department of Transportation facility, under the control of the NTSB. The additional examinations and forensic deconstruction of these components will occur there. The investigative team has confirmed that workers were adjusting tension on the two tensioning rods located in the diagonal member at the north end of the span when the bridge collapsed. They had done this same work earlier at the south end, moved to the north side, and had adjusted one rod. They were working on the second rod when the span failed and collapsed. The roadway was not closed while this work was being performed. On March 21, 2018 U.S. Transportation Secretary Elaine Chao asked the department 's inspector general to probe whether a federally funded UniversityCity pedestrian bridge complied with all rules. A subsequent internal memorandum from the Inspector General of the U.S. Department of Transportation, dated March 22, 2018 included the following statements : The Florida International University pedestrian bridge was funded in part through the Department of Transportation 's ( DOT ) Transportation Investment Generating Economic Recovery ( TIGER ) discretionary grant program. 1 The Federal Highway Administration administered the grant funds for the project. On March 19, the Secretary of Transportation requested that we initiate an audit to evaluate whether the project complied with Federal requirements and specifications. On March 20, Senator Bill Nelson, Ranking Member of the Committee on Commerce, Science, and Transportation, requested that we also review the implementation and oversight roles of all parties on the project. We share these concerns about the collapse, and we are committed to supporting the Department 's efforts to improve transportation safety. Accordingly, the objective of our audit will be to assess whether the Florida International University pedestrian bridge met Federal and DOT requirements for the TIGER application, approval, and grant agreement processes. On March 28, 2018 the Miami Herald reported they were denied access to FIU documents related to the bridge construction, citing federal regulations that prevent release of non-public information related to the bridge construction and design project when an NTSB investigation is in progress. A lawyer for Reporters Committee for Freedom of the Press indicated more information should be released under the Florida Sunshine Law, due to intense public interest in the collapse.
