La gestione della sicurezza nelle attività di manutenzione del patrimonio edilizio affidate in Global Service o in generale con altre formule contrattuali è oggi un tema molto dibattuto dagli addetti ai lavori. A tal proposito le ricerche e le campagne di sensibilizzazione effettuate su questo tema a livello nazionale ed internazionale sottolineano l’importanza di un’attenta pianificazione e gestione degli interventi manutentivi e che ciò può comportare la significativa riduzione degli infortuni sul lavoro. Con questo lavoro di tesi si vuole proporre l’implementazione del modello gestionale della sicurezza negli appalti di manutenzione di immobili affidati con la formula contrattuale del Global Service. Lo scopo è quello di sopperire alla difficoltà attuale nella gestione dell’informazione in tema di sicurezza nei processi di manutenzione di un edificio. A tal fine è stato condotto uno studio sullo stato dell’arte analizzando le criticità del modello gestionale attuale e quelli che potrebbero essere i campi di intervento per ottenere i maggiori benefici. A seguire, lo studio della normativa, dei documenti a disposizione dei vari soggetti e di modelli gestionali non propri del campo manutentivo ma sempre nell’ambito di interventi edilizi ha permesso di sviluppare una serie di applicazioni da introdurre nel modello attuale. L’implementazione del modello proposta può essere suddivisa in tre diversi ambiti. Il primo comporta una serie di oneri a carico della Committenza e dell’Assuntore riguardanti la disciplina organizzativa per l’esecuzione dei lavori, la documentazione di sicurezza da fornire in fase di gara e pre-contrattuale da parte dell’Assuntore e un mansionario per i principali responsabili delle attività manutentive di entrambe le parti. Un secondo riguarda la gestione semplificata della documentazione attraverso l’informatizzazione del processo. I documenti a disposizione della Committenza vengono inseriti all’interno di un modello BIM che diviene un database di informazioni di sicurezza a cui tutti i soggetti coinvolti possono accedere. Il terzo consiste nel proporre uno strumento operativo per la gestione della sicurezza nei singoli interventi costituito da una “scheda attuativa” che contiene solo informazioni esecutive. Il risultato è un modello gestionale in cui una maggior attenzione ai temi della sicurezza fin dalla fase contrattuale comporta una semplificazione del flusso di documenti in fase realizzativa e una conseguente pianificazione più incentrata sui soli rischi dell’attività manutentiva. Infine, per applicare la ricerca condotta a un modello reale si è deciso di testare il modello gestionale su un caso studio, nello specifico la realizzazione dell’Ampliamento del Teatro alla Scala di Milano. L’applicazione ha portato a riscontrare l’effettiva semplificazione nell’acquisizione di informazioni di sicurezza utili alla pianificazione degli interventi manutentivi ma di conseguenza la difficoltà nell’avere a disposizione un modello BIM fin dalla fase di realizzazione dell’opera.

Abstract
Health & Safety for maintenance interventions on building heritage still remains an arguable matter, whether entrusted as Global Service or whatever contractual agreement. Researches and awareness campaigns concerning this issue have been promoted on both a national and international level, highlighting the importance of planning and managing accurately maintenance works and pinpointing the resulting opportunity to record a drop in work related injury rates. The thesis herein presented is intended to provide an implementation of safety management for maintenance works contracts drawn up according to the Global Service contractual form, which aims to compensate for actual hurdles noticed in managing safety information throughout maintenance process. In the first place, a review of the state of art has driven considerations upon actual management strategies, in terms of criticalities and possible rooms for improvement. Then, the analysis of Italian legislation, in addition to all relevant documentation available to the professionals involved and management systems adopted in other branches of the wider construction business, has lead to the identification of a set of plug-ins to be introduced to develop the current management system for maintenance works. The proposal for implementation can be split into three different headways. The first one involves several obligations for both Client and Contractor, concerning the management strategy for the execution of works, documentation about Health & Safety issues to be provided for the tender and the determination of roles and responsibilities of each sides professionals. The second step leads to arrange a streamlined documentation flow, achieved by adopting Information Technology (IT) tools, such as Building Information Models (BIM), as databases in which are collected all information required and that is available to all professionals involved. The last stage consists of providing a simplified operative tool for supervising executive phases of each intervention, featured by an ”operational attachment” that contains solely information about execution tasks. The upgraded management model obtained ensures that paying specific attention to Health & Safety concerns starting from the bid phase results then in a lean and smooth documentation flow during the execution phase, and consequently design and planning of maintenance works can be focused on evaluating safety risks only. At last, the management process here assumed has been tested on a real case study, consisting of enlargement works for Teatro alla Scala in Milan. From this simulation, two considerations emerged: an effective simplification of procedures for the acquisition of safety information, useful for maintenance works planning; on the other hand, having already at hand a BIM model of the building subject to maintenance works is still nowadays infrequent.File | Dimensione | Formato | |
