IL TERRITORIO COME VALORE TERRITORY AS A VALUE

Il Gruppo Sina, leader nel settore dell’ingegneria del territorio e nell’ingegneria di controllo, è impegnato da anni nella ricerca, studio, realizzazione e gestione di nuove opere nei settori della viabilità e dei trasporti.

Il Gruppo Sina, da sempre impegnato per la sicurezza stradale, nell’ambito del proprio impegno sociale, opera per diffondere la cultura della sicurezza. Visita il sito www.autostradafacendo.it

Ambiente Le strade realizzate con i PFU permettono di riciclare correttamente un rifiuto che diventa, così, preziosa risorsa.

Riduzione della rumorosità, elevata durabilità, resistenza agli agenti atmosferici, maggiore sicurezza e costi manutentivi ridotti nell’intero ciclo di vita. Questi i plus di un asfalto realizzato con l’aggiunta di polverino di gomma da Pneumatici Fuori Uso. Da Ecopneus – principale responsabile della raccolta e il

recupero dei PFU in Italia – l’impegno per l’informazione e la conoscenza di un asfalto sostenibile e dalle grandi prestazioni.

Strade & ambiente: con la gomma da PFU i vantaggi sono per tutti.

Corte dei Conti: migliorati gli investimenti e tempi piĂš rapidi per i pagamenti ai fornitori PiĂš investimenti su strade e autostrade, accelerati i tempi di pagamento dei fornitori, gestione economico-patrimoniale positiva per il quinto anno. Sono i punti positivi - rileva lâ&#x20AC;&#x2122;Ansa - della relazione di controllo della Corte dei Conti sulla gestione finanziaria di Anas spa per lâ&#x20AC;&#x2122;esercizio 2012. La gestione economico-patrimoniale dellâ&#x20AC;&#x2122;Anas - evidenziano i giudici contabili - si Ă¨ chiusa con un risultato positivo pari a 2,16 milioni di euro. Con riguardo alla situazione patrimoniale di Anas la Corte dei Conti evidenzia â&#x20AC;&#x153;un incremento degli investimenti nella realizzazione di strade e autostrade rispetto allâ&#x20AC;&#x2122;esercizio precedente, al netto degli ammortamenti effettuati, di 1.646,11 milioni di euro (pari al 9,3%). Nel corso del 2012, il Capitale Investito di Funzionamento Ă¨ passato da 1.287,09 a 1.599,66 milioni di euro. Tale variazione, pari al 24,3%, Ă¨ imputabile allâ&#x20AC;&#x2122;incremento di crediti commerciali e altre attivitĂ correnti e alla simultanea diminuzione dei Debiti commerciali, per effetto dellâ&#x20AC;&#x2122;accelerazione dei tempi di pagamento dei fornitoriâ&#x20AC;?. La posizione finanziaria debitoria netta, costituita dallâ&#x20AC;&#x2122;indebitamento finanziario al netto delle attivitĂ finanziarie non immobilizzate e delle disponibilitĂ liquide, â&#x20AC;&#x153;aumenta del 79,5%, passando da 343,16 a 615,93 milioni di euro. La variazione Ă¨ principalmente dovuta alla riduzione delle disponibilitĂ liquide e delle attivitĂ finanziarie non immobilizzate, pari a 723,80 milioni di euro, che hanno piĂš che compensato la diminuzione dei debiti verso le banche pari a 451,03 milioni di euroâ&#x20AC;?. Il conto economico consolidato - conclude lâ&#x20AC;&#x2122;Ansa - evidenzia una gestione caratteristica pari a â&#x2C6;&#x2019;74,3 milioni di euro con un peggioramento di 20,6 milioni di euro rispetto al 2011. La gestione finanziaria chiude con un saldo positivo e un incremento di 2,6 milioni di euro (piĂš 3,5 %).

Convegni Lâ&#x20AC;&#x2122;asfalto e il construction insieme a Verona

Bilancio positivo per lâ&#x20AC;&#x2122;â&#x20AC;&#x153;Expoâ&#x20AC;? del rail

Tutti, ancora una volta, per il rilancio. Stringendo i denti, ora piĂš che mai. Apre le porte un Samoter 2014 (Verona, 8-11 maggio) che non nasconde certo le difficoltĂ perduranti nei settori del movimento terra e dellâ&#x20AC;&#x2122;edilcantieristica, nonostante i primi spiragli di ripresa, ma non puĂ˛ che fare il suo mestiere storico e proporsi ancora una volta come punto di incontro per stringere le fila. E ripartire. A dare man forte al Salone una prima assoluta, ma giĂ abbondantemente annunciata - lâ&#x20AC;&#x2122;edizione veronese di Asphaltica, la fiera a marchio Siteb dedicata alle pavimentazioni in conglomerato bituminoso e, piĂš in generale, allâ&#x20AC;&#x2122;infrastruttura stradale. Con Veronafiere e Siteb, ricordiamolo, vanno citate molte altre associazioni di categoria, in prima fila per lo sviluppo del settore: da Aisem ad ANFIA, da Ascomac ad Assodimi, e poi Cantiermacchine, Comamoter, Imamoter, Ucomesa, Unrae e Unacea. Proprio Unacea tra lâ&#x20AC;&#x2122;altro ha reso noto il proprio sostegno alla manifestazione, a cui parteciperĂ con una propria lounge e unâ&#x20AC;&#x2122;area espositiva dedicata alle aziende associate: Canginibenne, Cga, Cifa, Cm, Euromecc, Fiori, G.F. Gordini, Lameter, Mantovanibenne, MessersĂŹ, Palazzani, Samep Tools, Sci Editrice, Simex, Turbosol e Uemme. Altri soci di Unacea partecipanti: Komatsu, MB, Sampierana Spa/Eurocomach e Usco. Sul fronte prodotto, dalla fiera mettono lâ&#x20AC;&#x2122;accento sul fattore high-tech (dai droni ai visori a realtĂ aumentata, dalle nanotecnologie ai materiali â&#x20AC;&#x153;autoriparantiâ&#x20AC;?). Molte novitĂ , poi, sono attese proprio da Asphaltica, sempre allâ&#x20AC;&#x2122;avanguardia sui temi, per esempio, della sicurezza e della tutela ambientale (dagli asfalti tiepidi alle calci che non fanno polvere). Tra gli ospiti internazionali segnalati, una delegazione irachena, che ha organizzato la â&#x20AC;&#x153;spedizioneâ&#x20AC;? veronese in collaborazione con Unido, lâ&#x20AC;&#x2122;Organizzazione delle Nazioni Unite per lo Sviluppo Industriale, che opera dal 2007 proprio in Iraq.

Porto di Marina di Carrara: installazione di un sistema di drenaggio efﬁcace e resistente come... il marmo

Committente Autorità Portuale di Marina di Carrara

Esigenza Implementare una rete drenante di raccolta delle acque piovane sulle banchine del porto.

Soluzione

Il porto commerciale di Marina di Carrara è il più importante scalo mondiale di movimentazione di prodotti lapidei, provenienti principalmente dalle cave delle vicine Alpi Apuane. Sulle sue banchine stazionano e vengono movimentate ogni giorno tonnellate di graniti e soprattutto di marmi bianchi, il cui pregio rende famosa la città di Carrara in tutto il mondo. Drenare rapidamente ed efficacemente le acque piovane che si riversano su queste aree particolarmente affollate di uomini e mezzi; individuare un sistema stabile, sicuro e resistente alle continue sollecitazioni determinate dal passaggio di carichi estremamente pesanti: queste, in sintesi, le esigenze dell‘Autorità Portuale di Marina di Carrara e che ACO ha saputo magistralmente soddisfare. La soluzione implementata sulle banchine del Porto di Marina di Carrara è costituita da un sistema di canali monolitici ACO Monoblock, in

classe di carico F900, realizzati in calcestruzzo polimerico, un materiale estremamente resistente agli agenti chimici come gli idrocarburi, e all‘acqua e l‘aria salina, capaci invece di intaccare i normali sistemi di drenaggio in calcestruzzo tradizionale. La linea di continuità degli elementi monolitici viene interrotta, ad intervalli costanti, da elementi di ispezione, con corpo in calcestruzzo polimerico e telaio e griglia in ghisa, trattata superficialmente in cataforesi per evitare la formazione di ruggine, in classe di carico F900, fissata senza bulloni grazie al sistema ACO Powerlock. Durante tutte le fasi progettuali, ACO ha affiancato e assistito il team di ingegneri progettisti e il committente, l‘Autorità Portuale di Marina di Carrara, anche per tutte le verifiche idrauliche di smaltimento delle acque meteoriche. La rete di drenaggio è stata, infatti, dimensionata dal punto di vista idraulico mediante il software ACO Hydro, un innovativo sistema di calcolo idraulico che considera un moto stazionario non uniforme. In questo caso, come in moltissimi altri, scegliere ACO ha significato poter contare su prodotti evoluti e certificati, su materiali dalle altissime prestazioni e, soprattutto, su un servizio di supporto gratuito che, dalla base della progettazione fino al compimento dell’opera, accompagna e semplifica il lavoro di ingegneri e progettisti.

Rete di drenaggio lineare per un‘estensione di circa 2.600 metri, costituita da: elementi monolitici da 1 m di lunghezza, conformi alla norma UNI EN 1433, in calcestruzzo polimerico, con sezione a V e luce netta 200; elementi di ispezione in calcestruzzo polimerico, con telaio e griglia in ghisa, classe di carico F900, sistema di fissaggio Powerlock e giunto di sicurezza ACO Drain per la tenuta stagna.

Filo diamantato per il traforo

Una volta lo scavo del tunnel di servizio spiegano da Tyrolit - lâ&#x20AC;&#x2122;opera Ă¨ entrata in una nuova fase di notevole complessitĂ , consistente nella realizzazione dei varchi di comunicazione tra il tunnel principale e, per l'appunto, quello di servizio, che avrebbe comportato lâ&#x20AC;&#x2122;esecuzione di 23 aperture della sezione di 3,5x3,5 m. â&#x20AC;&#x153;Lâ&#x20AC;&#x2122;opzione di utilizzare tecniche tradizionali di demolizione per lâ&#x20AC;&#x2122;intero intervento Ă¨ stata ben presto scartata in ragione dei rischi che le vibrazioni da queste indotte avrebbero potuto determinare, e della particolare geometria richiesta dal progetto per le volte dei varchi di comunicazione. Tali fattori combinati hanno perciĂ˛ indotto la direzione lavori a prendere in considerazione lâ&#x20AC;&#x2122;adozione di una tecnica di intervento mista, consistente nella preventiva esecuzione di una serie di tagli a filo diamantato per lâ&#x20AC;&#x2122;intero contorno della sezione di ognuna

54 Trafori Stradali

Da mezzo secolo attraverso le Alpi Fabrizio Apostolo

IL TRAFORO DEL GRAN SAN BERNARDO HA COMPIUTO 50 ANNI. UNA RICORRENZA, A CUI LESTRADE HA PARTECIPATO, ANCHE UTILE PER RICORDARE CHE QUESTO TUNNEL DI QUASI 6 KM TRA ITALIA E SVIZZERA È STATO LA PRIMA INFRASTRUTTURA DEL SUO GENERE AD ATTRAVERSARE LE ALPI. TRA I SUOI GRANDI NUMERI: OLTRE 27 MILIONI DI VEICOLI TRANSITATI DI QUI DAL 19 MARZO 1964. TRA GLI IMPEGNI FUTURI: QUELLO DI RIPRENDERE AL PIÙ PRESTO I LAVORI DELLA GALLERIA DI SERVIZIO E DI SICUREZZA INTERROTTI DOPO LA RISOLUZIONE DEL CONTRATTO CON L’IMPRESA.

Standard di rendimento elevati e silenziositĂ assicurata: ecco lâ&#x20AC;&#x2122;ultima generazione in fatto di sistemi di pompaggio Innovazioni a getto continuo. Come lâ&#x20AC;&#x2122;acqua da cui liberano i cantieri. Sono quelle che escono dalla fabbrica padovana di Varisco (ZZZ YDULVFRVSD FRP), una specializzazione storica nello sviluppo e nella produzione di pompe centrifughe autoadescanti per liquidi contenenti solidi in sospensione e pompe volumetriche per liquidi, nonchĂŠ di pompe centrifughe, multistadio verticali e sommergibili per drenaggio e dragaggio. Con unâ&#x20AC;&#x2122;orizzonte che spazia dalle piccole e grandi opere italiane e disseminate in ogni angolo del pianeta. Tra le sue novitĂ piĂš recenti, segnaliamo una pompa silenziata vuotoassistita di nuova generazione giĂ impiegata in alcuni cantieri (esempio in fig. 8). Tecnicamente, il sistema Ă¨ costituito da una pompa centrifuga â&#x20AC;&#x153;Zâ&#x20AC;? a girante aperta con passaggio di corpi solidi e da un separatore in cui lâ&#x20AC;&#x2122;aria puĂ˛ separarsi dal liquido ed essere aspirata da un depressore. Tra i vantaggi: innescamento automatico â&#x20AC;&#x153;a seccoâ&#x20AC;?, grande passaggio di corpi solidi che permette di usare i gruppi sia per pompaggio a cielo aperto sia per wellpoint; depressore senza lubrificazione: nessuna contaminazione dellâ&#x20AC;&#x2122;ambiente. La â&#x20AC;&#x153;ciliegina sulla tortaâ&#x20AC;? Ă¨ la nuova cabina Muteline, che rende ideale lâ&#x20AC;&#x2122;impiego nel sistema anche in aree sensibili allâ&#x20AC;&#x2122;impatto acustico. La sua carta dâ&#x20AC;&#x2122;identitĂ : cabina silenziata da 58 a 63 dB(A), livello di pressione sonora (LPA) a 10 m; serbatoio da 250 litri con autonomia di 35 ore e vasca raccolta spanti in acciaio (110% el volume totale del serbatoio); bordo paraurti sul perimetro della base, con raccordi non sporgenti; connessioni di aspirazione/mandata a soli 0,5 m dal livello del suolo; arresto di emergenza allâ&#x20AC;&#x2122;esterno della cabina; sistema di ventila-

zione senza griglia: temperatura di esercizio 45 Â°C (max); cofani con apertura verso lâ&#x20AC;&#x2122;alto, spinti da molle a gas, per una facile ispezione e manutenzione della pompa e del motore. Infine, alcune caratteristiche della 6" Diesel: alto rendimento (79%), alta resistenza alle acque torbide, fangose, sabbiose con solidi in sospensione, facile manutenzione, motore Perkins 404D-22 Diesel (2.200 cm3 di cilindrata), kW - 36 HP di potenza, stage 3Â°.

Calce a bassa polverositĂ , lâ&#x20AC;&#x2122;ente orobico fa da apripista Intervista allâ&#x20AC;&#x2122;ing. Renato Stilliti, responsabile del procedimento per la Provincia di Bergamo vorazioni. Lâ&#x20AC;&#x2122;abbinamento di performance e tutela di ambiente e lavoro ci ha portato quindi a inserire questa tipologia di prodotto, con le relative caratteristiche tecniche, anche nel nostro capitolato standard. In futuro adotteremo senzâ&#x20AC;&#x2122;altro questa soluzione, anche in ragione del fatto che le differenze di costi (in ogni caso sostenibili) sono bilanciate dai benefici ottenibili.

leStrade. Ingegner Stilliti, ci puĂ˛ descrivere lâ&#x20AC;&#x2122;intervento di realizzazione della nuova tangenziale Ovest di Caravaggio? Stilliti. Lâ&#x20AC;&#x2122;intervento rientra nellâ&#x20AC;&#x2122;ambito del potenziamento infrastrutturale dellâ&#x20AC;&#x2122;area bergamasca connesso alle due grandi opere della BreBeMi e dellâ&#x20AC;&#x2122;Alta VelocitĂ /Alta CapacitĂ ferroviaria in corso di realizzazione. Lâ&#x20AC;&#x2122;opera, in particolare, si iscrive in questâ&#x20AC;&#x2122;ultimo ambito (Ă¨ finanziato con il contributo di RFI, ndr) e, una volta realizzata, consentirĂ di collegare il casello autostradale della BreBeMi con la SP 185 Rivoltana, bypassando lâ&#x20AC;&#x2122;abitato di Caravaggio. Si tratta di una nuova strada di circa 4 km di lunghezza collocata in un contesto prettamente agricolo che non presenta opere dâ&#x20AC;&#x2122;arte complesse, a parte un sottopasso alla linea ferroviaria Treviglio-Cremona. I lavori consistono prevalentemente in scavi di sbancamento, realizzazione di sottofondi e rilevati, posa delle pavimentazioni. leStrade. Come siete arrivati alla scelta della tecnica della stabilizzazione e, in particolare, della novitĂ â&#x20AC;&#x153;antipolvereâ&#x20AC;?? Stilliti. Lâ&#x20AC;&#x2122;impiego di materiali innovativi, nel caso della variante di Caravaggio, nasce dalla proposta del fornitore della calce per la stabilizzazione, una tecnica che giĂ abbiamo adottato in altri interventi e per cui abbiamo optato anche in questo caso, date le caratteristiche del sito e il vantaggio di non dover reperire, con annessi trasporti, materiale vergine per la realizzazione dei rilevati. In piĂš in questo caso ci Ă¨ stato presentato un legante di nuova generazione in grado di evitare il sollevamento di polvere durante la lavorazione, e questo con grande beneficio sia per lâ&#x20AC;&#x2122;ambiente sia per il personale di cantiere. Abbiamo accolto subito questa proposta, anche perchĂŠ crediamo che il compito di chi lavora nelle amministrazioni pubbliche sia quello di valutare e sostenere le innovazioni che possano da un lato migliorare lâ&#x20AC;&#x2122;infrastruttura stradale e dallâ&#x20AC;&#x2122;altro la qualitĂ della vita e del lavoro di chi risiede e opere intorno ad essa. leStrade. Qual Ă¨ il suo giudizio generale sulla nuova tecnologia? E che sviluppi futuri ne prevede? Stilliti. Lâ&#x20AC;&#x2122;introduzione della calce a bassa polverositĂ Ă¨ stata recepita come variante al progetto esecutivo e lâ&#x20AC;&#x2122;impresa, anchâ&#x20AC;&#x2122;essa molto attenta allâ&#x20AC;&#x2122;innovazione, si Ă¨ dimostrata molto disponibile a occuparsene. Come Provincia siamo molto soddisfatti di questa â&#x20AC;&#x153;sperimentazioneâ&#x20AC;?: a differenza delle applicazioni tradizionali, in questo caso il sollevamento di polveri Ă¨ stato limitatissimo, mentre dal punto esecutivo non risultano differenze con le consuete la-

Supporta la campagna per la sicurezza stradale del gruppo ASTM-SIAS

Mettiti alla guida della tua vita. Scegli un comportamento responsabile!

Strade ben costruite ed efficienti sono una condizione necessaria per garantire la sicurezza della circolazione: questo è l’impegno quotidiano del Gruppo ASTM-SIAS. Ciò nonostante il fattore umano risulta tragicamente determinante e incide negativamente sulle statistiche di settore. Con l’obiettivo di dare un contributo alla crescita della nostra società, abbiamo ideato questa campagna confidando nell’uomo, certi che un utente meglio informato metterà in pratica comportamenti virtuosi.

Campagna per la sicurezza stradale

Problemi? NON RISCHIARE: CHIAMA! CI FAREMO IN QUATTRO PER AIUTARTI E PROTEGGERTI

NOI PER VOI Ogni autostrada del Gruppo ASTM-SIAS è servita da un centro di controllo del traffico, a tua disposizione tutti i giorni, 24 ore su 24. Quando usi le colonnine SOS entri immediatamente in contatto con un nostro operatore del centro di controllo del traffico, che è in grado di localizzare immediatamente la tua posizione e di contattare i servizi di emergenza di cui hai bisogno: il servizio di assistenza al traffico del Gestore, il Servizio Polizia Stradale, il servizio medico urgente 118, i Vigili del Fuoco 115. Le autorità nazionali e i Gestori del Gruppo ASTM-SIAS migliorano progressivamente tali servizi all’utenza grazie anche alla cooperazione internazionale nell’ambito di Programmi Europei. Ad esempio EasyWay, programma co-finanziato dalla Commissione Europea (DG Move), ha come obiettivo il miglioramento nella gestione del traffico e la gestione delle emergenze grazie all‘implementazione di sistemi di trasporto intelligenti. Gli operatori del servizio di assistenza al traffico e gli operatori di pubblica sicurezza della Polizia Stradale sono equipaggiati con pannelli segnaletici, con torce e con altri strumenti che

possono mettere in sicurezza il traffico, anche in caso di incidente e guasto dei veicoli. Metti il giubbotto retroriflettente, proteggi il tuo veicolo, metti in sicurezza il traffico con il triangolo ed attendi il soccorso in un luogo sicuro. Stai bene attento, se decidessi di oltrepassare il guardavia, verifica prima cosa c’è dall’altra parte: potresti essere su un viadotto o comunque su una sezione sopraelevata o molto scoscesa. In caso di incidente, si potrebbe formare una coda alle tue spalle in grado di rallentare l’arrivo dei soccorsi. Anche poche decine di secondi sono per noi importanti. Più rapidamente ci informi e più velocemente arriveremo in tuo soccorso. Quando? In qualunque situazione di pericolo o quando hai bisogno di soccorso meccanico. Cosa? Usa le colonnine SOS e chiedi aiuto al Gestore Autostradale. Perché? 24 ore su 24 noi teniamo a tua disposizione un servizio per aiutarti, per proteggere la tua vita e quella degli altri.

Misure DEF, il commento della presidenza OICE Lâ&#x20AC;&#x2122;OICE, in una nota dellâ&#x20AC;&#x2122;11 aprile, ha commentato positivamente le misure annunciate con il DEF: â&#x20AC;&#x153;Sul documento presentato - ha detto il Presidente OICE, ing. Patrizia Lotti - pur riservandoci commenti piĂš analitici, il nostro giudizio Ă¨ complessivamente positivo. Le risorse destinate al tema della prevenzione e della riduzione del rischio idrogeologico, per realizzare immediatamente interventi cantierabili che risolvano le emergenze piĂš rilevanti, rappresentano senza dubbio un segnale positivo. Riteniamo, perĂ˛, /ÂśLQJ 3DWUL]LD /RWWL che per affrontare in maniera piĂš efficace un tema cosĂŹ complesso occorra avviare un grande sforzo progettuale e di studio delle criticitĂ sul territorio, mettendo a punto un sistema di interventi piĂš organico e sistematico, con una reale programmazione e con coerenti risorse per lo studio e lâ&#x20AC;&#x2122;analisi sul territorioâ&#x20AC;?. Lâ&#x20AC;&#x2122;OICE fa anche una proposta operativa: â&#x20AC;&#x153;Ă&#x2C6; nostro convincimento - continua Patrizia Lotti - che per questi temi, ma anche per favorire in generale lâ&#x20AC;&#x2122;utilizzazione dei fondi comunitari, si possa immaginare di costituire un Fondo rotativo per studiare e progettare gli interventi, utilizzabile dagli enti locali. In sostanza si tratterebbe di replicare, per altre finalitĂ e con altre modalitĂ , ciĂ˛ che Ă¨ stato proposto nel DEF con il fondo nazionale per la progettazione di opere in PPP (Fondo equity per progetti greenfield). Avvertiamo infatti una forte richiesta di progettualitĂ che si scontra perĂ˛ con lâ&#x20AC;&#x2122;assenza di risorse e questo impedisce anche il raggiungimento di una adeguata qualitĂ della progettazioneâ&#x20AC;?. Positiva viene giudicata anche lâ&#x20AC;&#x2122;impostazione del PNR sul fronte della riduzione dei costi e della revisione della spesa: â&#x20AC;&#x153;Vanno senzâ&#x20AC;&#x2122;altro nella giusta direzione i tagli agli enti inutili e la revisione della spesa, se ovviamente le risorse recuperate saranno reinvestite anche sulla spesa in conto capitale, che invece risulta in ulteriore e sensibile riduzione. Sul tema del ruolo dellâ&#x20AC;&#x2122;AVCP, sommessamente invitiamo ad una grande cautela e ponderazione per ben valutare le specificitĂ dei diversi settori, afferenti non solo ai lavori pubblici, coinvolti dalle attivitĂ dellâ&#x20AC;&#x2122;AutoritĂ e le indicazioni che vengono dalle direttive europee sul piano di una regia unitaria del mercato dei contratti pubblici. Câ&#x20AC;&#x2122;Ă¨ poi un tema piĂš generale, solo in parte affrontato, che Ă¨ quello del ruolo delle Pubbliche Amministrazioni che, proprio nellâ&#x20AC;&#x2122;ottica di un efficientamento della spesa pubblica, riteniamo che debbano essere orientate piĂš sulle fasi di programmazione e controllo e meno su quelle puramente tecnico-progettualiâ&#x20AC;?. Anche sullâ&#x20AC;&#x2122;esigenza di semplificazione normativa lâ&#x20AC;&#x2122;OICE condivide lâ&#x20AC;&#x2122;intervento sulla finanza di progetto: â&#x20AC;&#x153;In attesa del recepimento delle nuove direttive sugli appalti pubblici, Ă¨ assolutamente condivisibile lâ&#x20AC;&#x2122;idea contenuta nel DEF di estrapolare la disciplina sul project finance dal complesso delle norme sugli appalti e avviare cosĂŹ unâ&#x20AC;&#x2122;operazione di chiarezza e semplificazione normativa che sia in grado di dare certezza a tutti gli operatori sia per il closing finanziario degli interventi, sia in prospettiva per attrarre capitali stranieriâ&#x20AC;?.
