438 blocks910 tons !

La particularité du bat 193 ne permet pas un accès aisé et rapide pour les livraisons (seule une petite

partie des remorques est accessible avec le crochet du PR 591 (zonage orangé). De plus, le stockage sur place est très limité, ce qui implique une réalisation

en flux tendu…

Livraison des 438 blocs nécessaires : ~3 semaines/3 personnes -> 2.25 FTE/mois

En recouvrement pour une partie

Réalisation du blindage : ~3 semaines/3 personnes -> 2.25 FTE/mois

1 FTE/mois = 8100 CHF soit 4.5 * 8100 = 36450 CHF

secured Start blocks transfer and assembly

in AD hall ASAP (impact on AD): 16th November 2015

Simultaneous assembly estimated to last 4 weeks: could be finished by end 2015

Rest of shielding installation (exp area) + laser barracks depends on GBAR schedule
