Post-Earthquake Reconstruction of the Historic City Center of l‘Aquila: A Proposal Concerning the Rubble Transportation Problem

== Abstract ==

Post-earthquake reconstruction of the historic city Centre of L’Aquila, Italy, can be considered as the largest building site now under operation in Europe. The earthquake that hit  the  city  of  L’Aquila  on  the  6th  April  2009  generated  a  so-called  seismic  crater  that comprises  56  municipalities  and  concerns  an  area  of  almost  2.400  Km2.  The  earthquake  of  2009  destroyed  or  severely  damaged  all  historic  buildings  of  the  city  Centre.  Nowadays,  in 2020  there  are  more  than 8.000 completed construction projects that produced almost 4.000.000  t  of  removed rubble.  The  reconstruction  process  of  L’Aquila  has  been  soon defined  as  “the  biggest construction  site  of  Europe”.   This experience of managing a huge  number  of  construction projects  in  the  same  town  highlighted  the  need  of  a  multi-project  coordination  of  the  re-construction activities, and a central  co-ordination office has been  created.  Problems  concerning  the  co-ordination  of  many  construction  sites  that  are located  very  close  to  each-other  are  many  and  are  related  to  the  organization  and  sharing  of different  resources:  space  for  tower  cranes,  access  routes  for  vehicles,  space  for  temporary scaffoldings  and  space  for  debris  storage  and  disposal.  The  programme  management  of these production resources needs to be based on a  General Management plan that is proposed.  In  particular,  the  problem  of  rubble  production, transport  and storage  has  been addressed in the plan proposition. In fact, the production,  transportation  and  storage  of rubble produced by construction operations can be considered one of  the  main  criteria  of the multi-project  optimization process  needed for the co-ordination of the city reconstruction. As a  pilot  study,  a  simulation  of  project  co-ordination  of  an  urban  area  that includes eleven building blocks under re-construction has been performed with the  traditional  resource levelling  procedure.  Therefore,  the  reconstruction  programme  schedule  of  the  area  has  been optimized considering the process constraints due to quantitative limits of rubble transportation and disposal.
