Beatriz Elena Pérez González, Roberto Sánchez Linaje and Guillermo Amengual Giardín, members of the Construction Department at ABACO INTERNATIONAL LOSS ADJUSTERS, have co-authored an article entitled Insurance Policies for the Construction of Rapid Transport Lines which appeared in Volume 7 of the magazine REASEGURO CONTEMPORANEO, published by AON BENFIELD. The article presents a brief description of the principal categories of urban rail transit projects and analyses their main characteristics, including a discussion of the various construction procedures used in their execution, with particular attention paid to construction projects using tunnel boring machines. The manner in which losses in such projects are handled in Construction Insurance Policies is also discussed, in addition to the various coverage options and most frequently used Clauses.
