Forensic Engineering and Expert Advice

 

This page describes only a small part of my assignments of forensic engineering and expert advice. Confidentiality reasons and Client’s non-disclosure preferences restrict the access to the remaining information.

  • Vinci-Construction Grands Projets (2015). Atlantic Bridge, Panama. The Atlantic Bridge includes a main cable-stayed span and incrementally launched approaches. My duties included providing expert advice in relation to AASHTO-LRFD provisions on the use of combinations of internal and external tendons for launch post-tensioning.
  • Lloyd’s-HCCW (2014). Indian River Bridge, Delaware Seashore National Park, DE, USA. The Indian River Bridge is a 533m prestressed-concrete, ribbed-slab cable-stayed bridge with a 290m main span. My duties included providing expert advice in relation to the design and fabrication of the form travelers used for in-place casting of the main cable-stayed span.
  • HNTB (2009-2010). Hathaway Bridge, Panama City, FL, USA. Forensic investigation of the design of 2.5km of precast segmental bridges showing deterioration of the midspan closures of 100m balanced cantilever spans and the adjacent epoxy joints. My duties included thermal warping analysis of short-line match-cast segments, time-dependent erection analysis of warped segments with solid finite-element models, and testing cores extracted from the epoxy joints to assess shear capacity.
  • Pizzarotti (2005-2006). Simeto Bridge for the Catania-Siracusa Highway, Italy. Forensic investigation of the collapse of two bridge spans, three bridge piers, and the self-launching gantry used for bridge erection. My duties included leading the emergency response to failure, documenting site conditions, gathering information, interviewing construction crews, and advanced structural analysis for the subsequent forensic investigation.
  • Modena scarl (2004). Modena Bridges, TAV High Speed Railway, Modena, Italy. Emergency response to a potentially catastrophic failure of a 105m, 900t twin-girder overhead MSS for span-by-span casting of 58m spans. As freelance consultant, my duties included on-site management of the emergency response to failure, recovery of the machine and independent review of the design of repairs.
  • Cogefar (1989). Reconstruction Project, Lot E, Naples, Italy. Emergency response to a potentially catastrophic failure of the support columns of a 110m, 900t single-girder overhead MSS for span-by-span casting of 47m spans. As freelance consultant, my duties included on-site management of the emergency response to failure and independent review of the design of repairs.
