Design Review of Special Equipment

 

Throughout my professional carrier, I have performed the independent design review of 4 movable scaffolding systems (MSS), a self-launching gantry for macro-segmental spans, a self-launching gantry for span-by-span erection of precast segmental bridges, and 2 wheeled carriers with self-launching underbridge for on-deck transportation and placement of precast spans. I have also reviewed the design of multiple advancing shoring systems, the falsework for two arches, the launch set and strand-jacking equipment for 2 incrementally-launched steel U-girders, and a forming carriage for the deck slab of a steel-composite bridge. The following projects do not include forensic engineering assignments.

  • Pizzarotti (2006). Porcaria and Gornalunga Bridges for the Catania-Siracusa Highway, Italy. Independent design review and certification for production of a 150m, 1230t twin-truss overhead self-launching gantry for span-by-span erection of precast segmental bridges. As freelance consultant, my duties included 3D modeling of the machine, placement analysis of design-governing segments, self-launch analysis along curvilinear trajectories, and analysis of lateral torsion-flexure buckling in critical launch stages.
  • Pizzarotti (2006). Agnone 1 Bridge for the Catania-Siracusa Highway, Italy. Independent design review and certification for production of an 88m, 780t underslung MSS for span-by-span casting of a sequence of 41m half-span segments of a varying-depth bridge with 82m span. As freelance consultant, my duties included 3D modeling and analysis of the machine and on-site technical assistance during load testing.
  • Pizzarotti (2005). Simeto and Mulinello Bridges for the Catania-Siracusa Highway, Italy. Independent design review and certification for production of a 165m, 1290t twin-truss overhead self-launching gantry for erection of adjacent macro-segmental PC spans comprising four 730t segments in every 95m span. As freelance consultant, my duties included 3D modeling of the entire machine (self-launching trusses, winch-trolleys and support portals), analysis of placement of pier-cap and midspan segments in rectilinear and curved spans, self-launch analysis, and analysis of lateral torsion-flexure buckling with different segment configurations and in critical launch stages.
  • Modena scarl (2004). Modena Bridges, TAV High Speed Railway, Modena, Italy. Independent design review and certification for production of a 105m, 900t twin-girder overhead MSS for span-by-span casting of 58m spans. As freelance consultant, my duties included 3D modeling and structural analysis, self-launch analysis, and site assistance during site commissioning and load testing of the MSS.
  • Pizzarotti (2001). Modena Bridges, TAV High Speed Railway, Modena, Italy. This extremely challenging project required prefabrication, transportation and placement of 755 single-track high-speed railway spans in 30 months, for a total bridge length of 24.8km. The 33m, 740t spans were transported on the completed bridge with 60m wheeled portal carriers and positioned with 78m self-launching underbridges. As freelance consultant, my duties included full independent design review and certification for production of wheeled carriers and underbridges, and site assistance during their site commissioning and load testing.
  • Pizzarotti (2001). Modena Bridges, TAV High Speed Railway, Modena, Italy. Independent design review and certification for production of a 113m, 1500t twin-truss overhead MSS for span-by-span casting of 58m spans. As freelance consultant, my duties included 3D modeling and analysis of the entire machine (self-launching trusses, tower-crossbeam assemblies and suspended casting cell), self-launch analysis, and site assistance during site commissioning and load testing of the MSS.
  • Bonatti-Kirchner JV (1995-1997). Schrotetal Bridge, Madgeburg, Germany. This project included two adjacent 500m steel-composite bridges built by incrementally launching two U-girders from the left abutment and two U-girders from the right abutment, and by strand-jacking two varying-depth transition spans into position for welding. The concrete slab was cast segmentally with a 23m forming carriage. As construction engineer, my duties included the independent design review of the launch set (segment welding supports, articulated launch bearings, trussed launch nose, thrust systems), the strand-jacking equipment for the U-girders, and the 190t self-launching forming carriage for in-place casting of the deck slab.
  • Cogefar (1987-1990). Reconstruction Project, Lot C, Naples, Italy. This project included 0.8km of PC bridges cast span-by-span on advancing shoring and 1.8km of PC bridges cast span-by-span with a 110m, 900t single-girder overhead MSS designed for weekly cycles with full-span cage prefabrication behind the abutment. As construction engineer, my duties included the independent design review of the MSS, its assembly on an existing bridge, and multiple falsework systems for span-by-span advancing shoring.
  • Cogefar (1987-1990). Reconstruction Project, Lot E, Naples, Italy. This project included 1.9km of steel-composite bridges erected with ground cranes, a 420m steel-composite bridge built by incremental launching on 110m spans, 0.5km of PC bridges cast span-by-span on advancing shoring, and 0.6km of PC bridges cast span-by-span with the MSS of the adjacent Lot C. As construction engineer, my duties included the independent design review of multiple falsework systems for span-by-span advancing shoring.
  • Cogefar (1985-1987). Lot C of State Road 36, Dervio, Italy. This project included two PC arches cast on 40m-tall falsework (more than 30km of steel tubes and 25.000 joints) to protect bridges and tunnel inlets from falling boulders. As construction engineer, my duties included the independent design review of the tubular falsework.
  • Cogefar (1982-1987). State Road 36, Lecco, Italy. My first bridge construction project included 1.4km of multi-span prestressed concrete (PC) bridges cast on advancing shoring on 40m spans. As construction engineer, my duties included the independent design review of multiple falsework systems for span-by-span advancing shoring, including two special multi-span railway crossings.
