.IT DESIGN
SISTEMA DI DRENAGGIO AD ALTE PRESTAZIONI IDRAULICHE PER AREE VASTE
Il nuovo sistema di drenaggio lineare FUNNEL garantisce il rapido e sicuro smaltimento delle acque piovane che insistono su grandi superfici, come autostrade ed aeroporti. E’ costituito da una serie di imbuti in ghisa sferoidale provvisti di griglia superiore del medesimo materiale, che si innestano ad un collettore inferiore in tubo corrugato. Le altissime performance idrauliche sono garantite da 2 scarichi 110 per metro lineare, innestati su un collettore di diametro variabile da 250 a 1200. Il volume dell’acqua raccolta viene così smaltito, o direttamente nel corpo recettore finale, o in altre tubazioni principali, tramite un sistema di pozzetti. BREVETTATO

Giornata del Cantoniere 2012 tra memoria e nuove sfide Si è svolta il 18 dicembre nell’Aula Magna della Scuola Superiore di Polizia, a Roma, la decima edizione della giornata del Cantoniere. “L’Anas - ha affermato l’Amministratore unico Ciucci (nella foto) - si è confermata leader non solo per la capacitĂ di saper realizzare opere infrastrutturali nel rispetto dei tempi e delle previsioni di spesa, ottenendo da TĂœV la certificazione ISO 9001 per l’intera attivitĂ svolta ma, soprattutto, per essersi affermata per molti anni come prima stazione appaltante d’Italia. L’Anas è pronta nel 2013 a cambiamenti straordinari. Quest’anno, infatti, è avvenuta una vera e propria rivoluzione: dal 1° ottobre 2012 il ruolo e le funzioni di concedente degli oltre 5700 km della rete autostradale a pedaggio, cosĂŹ come la vigilanza sull’esecuzione dei lavori di costruzione delle opere autostradali e il controllo della gestione delle autostrade in concessione, sono stati trasferiti dall’Anas direttamente al Ministero. Il futuro dell’Anas è quindi delineato: continuerĂ nella gestione diretta di una rete viaria di oltre 25mila kmâ€?. Lo stesso giorno Ciucci ha deposto una corona in memoria dei cantonieri che hanno perso la vita in servizio nel corso degli oltre 80 anni di attivitĂ dell’Anas.

tĂ dei flussi economico-finanziari negli appaltiâ€?. Gli interventi riguardano 4 svincoli (Lanzo, Casal di Pari, Pari e Palazzo Lama), 8 viadotti da adeguare e 6 da realizzare ex novo, 3 gallerie naturali per quasi 2,5 km e 7 gallerie artificiali, per un investimento complessivo di 236 milioni di euro. “Con l’avvio dei lavori in questo tratto - ha proseguito Ciucci - saranno completati 9 degli 11 lotti complessivi del tronco Grosseto-Siena, pari a circa 48 km su 63 totaliâ€?. Attualmente è in fase di approvazione il progetto esecutivo e sono pressochĂŠ concluse le attivitĂ propedeutiche e l’allestimento delle aree di cantiere. Tra le recenti importanti aperture al traffico lungo l’arteria ricordiamo quelle risalenti al marzo scorso e relative ai lotti 2 e 3, nel territorio comunale di Civitella Paganico (Grosseto).

La giunta regionale veneta ha espresso parere favorevole di giudizio di compatibilitĂ ambientale relativo alle varianti che interessano i lotti della Superstrada Pedemontana Veneta denominati â&#x20AC;&#x153;Lotto 2 tratta B dal km 29+300 al km 38+700â&#x20AC;? e â&#x20AC;&#x153;Lotto 3 tratta F dal km 54+755 al km 55+494â&#x20AC;?. Le varianti in questione sono state proposte dal Commissario Delegato per lâ&#x20AC;&#x2122;Emergenza pedemontana e il provvedimento regionale rientra nella procedura di Valutazione dâ&#x20AC;&#x2122;Impatto Ambientale nazionale prevista per lâ&#x20AC;&#x2122;opera. Il Lotto 2 tratta B si sviluppa tra la progressiva km 29+300, situata nel Comune di Breganze, sino alla progressiva km 38+900, situata nel Comune di Marostica. La revisione progettuale si è resa necessaria a seguito della delibera Cipe che, per il Tratto Breganze-Nove, ha prescritto lâ&#x20AC;&#x2122;individuazione, in sede di progettazione, di una soluzione che concentri in un unico corridoio infrastrutturale sia la SPV che la viabilitĂ locale e di servizio. Il Lotto 3F, si sviluppa dal km 54+755,15 al km 55+494,91, interessando Riese Pio X e San Zenone degli Ezzelini. La revisione deriva, in questo caso, dalla richiesta della Provincia di Treviso e dei Comuni di procedere con una nuova progettazione della parte di tracciato secondo le indicazioni formulate dagli enti interessati in un protocollo dâ&#x20AC;&#x2122;intesa, che ha individuato una nuova soluzione tecnico-progettuale per lo svincolo ricadente nei due comuni citati.

ALI N R E V IN E M Neve GOM ORE! V A F R E P … E CATENE
Qui continua l’avventura della SICUREZZA STRADALE Qui continua l’avventura. Quella che avevamo raccontato proprio su leStrade qualche numero fa, per l’esattezza sul fascicolo di giugno 2012, e su cui eravamo tornati nel numero dello scorso dicembre. Sebbene, a dirla tutta, come già suggerivamo, di avventura proprio non si dovrebbe trattare perché la sicurezza stradale è una cosa seria, serissima, che, soprattutto di questi tempi sempre più tecnologici non è utopia pianificare come si deve. Lo fanno quotidianamente i gestori delle nostre infrastrutture, uno dei vertici del
triangolo della road safety, con veicoli e utenti. Da tempo, questi “attori” stringono alleanze in nome dell’obiettivo prioritario, pensiamo allo sviluppo dell’automotive nella sua ricerca di dialogo istantaneo con le reti (sistemi cooperativi), o a quello dello stesso settore infrastrutture in campo ITS: monitorare quel che accade sulle strade e utilizzare i dati per informare l’utenza in tempo reale rappresenta un formidabile contributo al miglioramento della sicurezza. Guardando a entrambi i casi, il successo, pur in tempi critici,
di un appuntamento come il congresso mondiale ITS di Vienna, lo scorso ottobre, non può che far ben sperare. Poi, ricordavamo, ci sono le campagne di sensibilizzazione. Come quella messa in pista dalle società del Gruppo ASTM-SIAS, in collaborazione con un lungo elenco di partner tra cui leStrade. La campagna, dal titolo “Mettiti alla guida della tua vita. Scegli un comportamento responsabile!”, si basa su un’idea antica e allo stesso tempo innovativa: popolare una serie di vignette con personaggi fortemente
www.autostradafacendo.it
DOPO AVER â&#x20AC;&#x153;CONQUISTATOâ&#x20AC;? IL WEB E I BIGLIETTI DEL PEDAGGIO, LE VIGNETTE DELLA CAMPAGNA SICUREZZA DEL GRUPPO ASTM-SIAS HANNO POPOLATO MOLTI ALTRI MEZZI DI COMUNICAZIONE, TRA CUI PERSINO UN CALENDARIO. SEGNO DEL SUCCESSO DI UNâ&#x20AC;&#x2122;INIZIATIVA DI SENSIBILIZZAZIONE AI COMPORTAMENTI CORRETTI CHE, ATTRAVERSO Lâ&#x20AC;&#x2122;IRONIA, PUNTA DRITTO ALLâ&#x20AC;&#x2122;OBIETTIVO DEGLI OBIETTIVI: SALVARE VITE UMANE.
Mettiti alla guida della tua vita. Scegli un comportamento responsabile!

caratterizzati che, con le loro gesta, comunicano chiaramente - attraverso tutti i canali disponibili - cosa si deve fare (o non fare) quando ci si trova nellâ&#x20AC;&#x2122;ambiente-strada. Ecco allora che il disinvolto ingegnere Roberto Azzarda precipita con lâ&#x20AC;&#x2122;auto dallâ&#x20AC;&#x2122;alto di un palazzo. Didascalia della vignetta: â&#x20AC;&#x153;Cadendo dal terzo piano, ti pianti a 50 km/h. Ti butteresti giĂš senza cintura?â&#x20AC;?. Oppure ecco lâ&#x20AC;&#x2122;ausiliario alla viabilitĂ Edoardo Svelto e lâ&#x20AC;&#x2122;agente della Polstrada Emanuele Giusto che accorrono in aiuto dellâ&#x20AC;&#x2122;utente con lâ&#x20AC;&#x2122;auto in panne di fronte a un imbocco di galleria. Il messaggio della vignetta: â&#x20AC;&#x153;Hai dei problemi? Non rischiare, chiamaci! Correremo a proteggertiâ&#x20AC;?. Eroi e antieroi, dunque, come nella migliore tradizione fumettistica e caricaturale italiana, fin dalle sue origini tardo-ottocentesche veicolo moderno e ideale per far arrivare a destinazione i messaggi. Quello sulla sicurezza di ASTM-SIAS si inserisce in una lunga vicenda di educational per immagini niente affatto retorico e paludato (che va dal Signor Bonaventura alle saghe dei topi e dei paperi

Campagna sicurezza sugli scudi anche nel 2013 (in alto, il calendario) grazie anche al supporto sempre piĂš convinto di promotori e partner e allâ&#x20AC;&#x2122;entrata in scena di nuovi personaggi (sotto, le quattro new entry)
Disney, nel fumetto, e che ritroviamo nellâ&#x20AC;&#x2122;audiovisivo, per esempio, nel cartoon alla Bruno Bozzetto o nella commedia allâ&#x20AC;&#x2122;italiana, si pensi a film come Il sorpasso) e la sa innovare grazie a due fattori tipici della nostra epoca: lâ&#x20AC;&#x2122;utilizzo dei new media da un lato e la capacitĂ di fare network dallâ&#x20AC;&#x2122;altro. La campagna, infatti, nasce nelle 52 tavole disegnate e subito balza sul web, da www.autostradafacendo.it al video su YouTube â&#x20AC;&#x153;Safety Road Gameâ&#x20AC;?, per arrivare ai pop-up diffusi sui siti Internet dei partner istituzionali. Sul versante â&#x20AC;&#x153;socialâ&#x20AC;?, invece, la novitĂ sta proprio nellâ&#x20AC;&#x2122;aver saputo raccogliere intorno al progetto una lunga serie di supporter istituzionali e industriali, tra lâ&#x20AC;&#x2122;altro in continua crescita. Tutti fortemente motivati a dare il proprio contributo in termini di storie, idee e best practice. Ma il network parte dalla rete per toccare ben presto altri lidi: il movimento genitori Moige con lâ&#x20AC;&#x2122;opuscolo â&#x20AC;&#x153;Istantanee di sicurezzaâ&#x20AC;?, per esempio, lezioni di comportamenti virtuosi in autostrada nelle scuole con presenza in aula di esperti, laboratori didattici a Lucca Comics, senza dimenticarci dei 37 milioni di ticket del pedaggio (con annessa vignetta) distribuiti ai caselli delle nostre autostrade. Gli ultimi avvistamenti di questa avventura che, proprio come farĂ il neonato icona della campagna, cresce a vista dâ&#x20AC;&#x2122;occhio: lâ&#x20AC;&#x2122;album da colorare per bambini â&#x20AC;&#x153;Dai un colore alla sicurezza!â&#x20AC;?, i segnalibri o il fiammante Calendario 2013, di cui diamo un assaggio in queste pagine.
Sul campo, ovvero sulla strada, si sfidano nellâ&#x20AC;&#x2122;eterna partita tra il bene (i comportamenti corretti) e il male (la â&#x20AC;&#x153;disinvolturaâ&#x20AC;? al volante che mette a repentaglio la vita, propria e degli altri). Fuori dal campo, però, vanno a mangiare insieme in pizzeria, segno che a un happy end si può e si deve arrivare. Dopo la pizza, chi guida è lâ&#x20AC;&#x2122;agente Emanuele Giusto, che ha rinunciato alla birra e dato il buon esempio. Si spera che lo segua anche Carletto Azzarda, figlio del disinvolto
Roberto e della prudente Cristina Sveglia, che rovescia il luogo comune della â&#x20AC;&#x153;donna al volanteâ&#x20AC;?. Ma le regole devono valere anche per quelle donne che il volante lo snobbano, come la fidanzata di Carletto, Ester Sciantosi, ancora in dubbio sulla differenza tra auto e discoteca. Poi câ&#x20AC;&#x2122;è la bimba, Pierina Azzarda, che va legata con la cintura e a sua volta deve farsi una ragione che il sedile è fatto per starci sopra tranquilli. Quindi, ecco i professionisti della strada, dal camionista Federico Prudente Pio, che celebra le virtĂš di â&#x20AC;&#x153;San Tachigrafoâ&#x20AC;?, al vigile del fuoco Alberto Risoluto fino al medico Claudia Semprepronta e a Edoardo Svelto, lâ&#x20AC;&#x2122;ausiliario della viabilitĂ protettore dei viaggiatori. Infine, gli ultimi arrivati. Sono: Mario Nero, guidatore aggressivo, Teresa Tormenta, guidatrice ansiosa e arrabbiata, Fabrizio Sotuttoio, guidatore ipersicuro, per concludere con Geremia Azzarda, nonno di Carletto.
E, come in tutti i serial del momento che si rispettano, crescono anche i personaggi. Anzi, si moltiplicano. Accanto ai â&#x20AC;&#x153;classiciâ&#x20AC;?, ecco dunque i guidatori â&#x20AC;&#x153;problematiciâ&#x20AC;? dai cognomi inequivocabili: Nero, Tormenta, Sotuttoio. Fino allâ&#x20AC;&#x2122;ultimo arrivato, il nonnino Geremia Azzarda. Alla fine della storia, ne siamo certi, converrĂ anche a loro imparare la lezione: comportarsi responsabilmente mettendosi al volante della propria vita.
ADESIONI IN CRESCITA Un nutrito staff di esperti che lottano con lâ&#x20AC;&#x2122;orologio per dedicare del tempo a raccontare i gesti della sicurezza, oltre che viverli ogni giorno. Ă&#x2C6; la squadra della campagna. Direttori esercizio, responsabili viabilitĂ , specialisti che di mestiere controllano lâ&#x20AC;&#x2122;efficienza delle infrastrutture, sono infatti diventati anche autentici testimonial: su Internet, sui giornali oppure nelle scuole. I promotori sono Ativa, Autostrada Asti-Cuneo, Salt, Sav, Sitrasb, Autocamionale della Cisa, Autostrada dei Fiori, Satap, Sitaf, Gruppo Sina. New entry: Autostrada Torino-Savona. In crescita la squadra partner, tra cui anche ONU, Ministero delle Infrastrutture, Polizia Stradale e Aiscat. Gli ingressi piĂš recenti: Milano Serravalle-Milano Tangenziali, Secolo XIX, Comune di Pisa, Provincia di Torino e Politecnico di Bucarest.

Prodotti Nuova generazione di escavatori ibridi
Dal Giappone allâ&#x20AC;&#x2122;Italia. Arriva nel Belpaese la seconda generazione dellâ&#x20AC;&#x2122;escavatore ibrido Komatsu HB215LC-1, una macchina - nota lâ&#x20AC;&#x2122;ad di Komatsu Italia, Alberto Caletti - â&#x20AC;&#x153;in grado non solo di garantire circa il 25% di risparmio sul consumo di carburante rispetto al tradizionale escavatore idraulico ma, soprattutto, di assicurare unâ&#x20AC;&#x2122;emissione inferiore di CO2. Quale azienda di riferimento a livello internazionale, siamo determinati a perseguire sempre piĂš caparbiamente lâ&#x20AC;&#x2122;obiettivo di una sinergica ricerca di tecnologia e riduzione dellâ&#x20AC;&#x2122;impatto ambientale. Il lancio in Italia dellâ&#x20AC;&#x2122;escavatore ibrido - equipaggiato con il Komatsu Hybrid System, che integra un motore elettrico di nuova generazione per la rotazione della struttura superiore, un motore per la generazione dâ&#x20AC;&#x2122;energia, un inverter, un condensatore ed un motore diesel è un nuovo, importante passo del Gruppo in questa direzioneâ&#x20AC;?. Caratterizzata da una potenza motore di 110 Kw e da un peso operativo di 21.220 kg, la macchina è una scelta appropriata anche per il cliente che stia valutando una macchina che lavorerĂ molto e avrĂ unâ&#x20AC;&#x2122;alta frequenza di rotazione della torretta. In questi casi, lâ&#x20AC;&#x2122;HB215LC-1 si può rivelare prezioso in quanto in grado di ridurre in maniera sensibile i consumi. +
Stabilizzazione innovativa
Acceleratore premuto sullâ&#x20AC;&#x2122;innovazione tecnologica al servizio delle tecniche di stabilizzazione del terreno e riciclaggio a freddo delle pavimentazioni. Ă&#x2C6; lâ&#x20AC;&#x2122;approccio di Bomag che, tra le varie novitĂ di Asphaltica 2012, ha presentato
la tecnologia di nuova concezione Flexmix finalizzata a garantire, attraverso la configurazione di nuovi standard nella miscelazione dei materiali, flessibilitĂ di utilizzo, grande produttivitĂ giornaliera e bassi costi di esercizio. â&#x20AC;&#x153;La possibilitĂ di poter modulare varie tipologie di miscelazione -

MPH 125 soddisfa due importanti esigenze: da un lato lâ&#x20AC;&#x2122;alta produttivitĂ e dallâ&#x20AC;&#x2122;altro la massima qualitĂ di frantumazione e miscelazione. Questi risultati sono possibili grazie alla nuova tecnologia Flexmix e al rinnovato design della camera di miscelazione della stabilizzatricericiclatrice MPH 125â&#x20AC;?. In aggiunta alle impostazioni tradizionali, Bomag ha inoltre ampliato le opzioni di utilizzo grazie allâ&#x20AC;&#x2122;aggiunta del flap supplementare per la miscelazione e la frantumazione: â&#x20AC;&#x153;Lâ&#x20AC;&#x2122;innovativo flap, a regolazione continua, agisce come barra di frantumazione allâ&#x20AC;&#x2122;interno della campana del rotore: se necessario, il materiale fresato viene catapultato sul flap supplementare e ulteriormente frantumato fino a raggiungere la dimensione necessaria. A ciò si aggiunge la regolazione dei giri del tamburo in 11 modalitĂ diverse in funzione delle condizioni di lavoro, riducendo cosĂŹ lâ&#x20AC;&#x2122;usura sia degli utensili che del
tamburo stesso al minimo e garantendo il miglior risultato di miscelazione con il minor impiego di energiaâ&#x20AC;?. Questa innovativa tecnologia è stata ulteriormente sviluppata fino a includere il primo BRS 05, il nuovo sistema per il cambio rapido dei portadenti in acciaio altamente resistente allâ&#x20AC;&#x2122;usura, concepito in particolare per la stabilizzazione del suolo. Il grosso vantaggio offerto da questo nuovo portadenti è, grazie al design semplice e di facile utilizzo, la sostituzione rapida gli utensili in qualsiasi situazione di lavoro direttamente in cantiere e con costi limitati. , +1 -

Tipologie di ampliamento: uno dei cardini del progetto è risultata la scelta più efficiente di soluzioni simmetriche (riutilizzo dei cavalcavia esistenti, diminuzione delle imbottiture dovute alle pendenze trasversali) piuttosto che asimmetriche (lavorazioni più agevoli, costi unitari di realizzazione minori, aumento delle produzioni)

6. Schema esemplificativo della circolazione veicolare da quartiere a quartiere (e da parcheggio a parcheggio), con mobilità alternativa, rispetto all’auto privata, all’interno di ciascun quartiere 7. Un buon esempio di suolo urbano rigenerabile: questo ampio parcheggio a raso a servizio di un impianto sportivo, utilizzato solo occasionalmente e quasi sempre vuoto, potrebbe essere rimpiazzato da un parcheggio multipiano, recuperando per altri usi buona parte del suolo 7

Un â&#x20AC;&#x153;pacchetto completoâ&#x20AC;? al servizio della realizzazione di una grande opera. Ă&#x2C6; quello proposto da Harsco, che, come nel caso del ponte russo, mette a disposizione un caposquadra e un numero di tecnici per supportare il progetto e assicurare che i processi di lavoro, meticolosamente pianificati, siano seguiti in loco. Non solo attrezzatura quindi, ma anche una dotazione completa di servizi a valore aggiunto che aiutano il processo costruttivo ad avanzare in modo rapido e sicuro. Raccogliendo il know-how delle proprie filiali nei diversi Pa-
10
esi, il gruppo, tra lâ&#x20AC;&#x2122;altro, nel 2011 ha ridisegnato la sua struttura definendo alcune aree di competenza. Nel nuovo assetto, la filiale italiana, con sede a Turate (Como), ha assunto un ruolo determinante come Centro di competenza per la progettazione di dighe e infrastrutture, diventando un punto di riferimento per tutto il gruppo. Insomma, oltre al know-how e alle sinergie tipiche di una realtĂ multinazionale come Harsco, câ&#x20AC;&#x2122;è anche molto ingegno di casa nostra - quello maturato in anni di supporto alle grandi imprese italiane allâ&#x20AC;&#x2122;estero.

Un nuovo luogo nellâ&#x20AC;&#x2122;antico luogo Enzo Siviero Istanbul, 10 giugno 2012. Due parchi-giardino separati da una via densa di un traffico frettoloso quando disattento. Le emergenze storiche di palazzi di pregio che ivi si affacciano, mal si accompagnano alle recenti edificazioni il cui anonimato contrasta palesemente con le stratificazioni culturali di questo angolo di cittĂ che tutto il mondo conosce. Il verde ben curato attrae i cittadini che nellâ&#x20AC;&#x2122;attraversamento della piazza quasi fuggono da un traffico veicolare fastidioso quanto assurdo. La vicinanza della Scuola di Architettura della prestigiosa Istanbul Technical University vede uno sciame continuo di studenti che, addestrati alla lettura della cittĂ , sembrano interrogarsi di continuo se si trovano veramente in un luogo denso di cultura per lo loro storia millenaria ovvero in un anonimo ambito privo o quasi di qualsiasi identitĂ . In effetti, i contrasti sono palesi e chiedono a gran voce di essere finalmente superati per re-interpretare gli spazi chiaramente disarticolati. Un pregevole torrino di pietra, antico serbatoio dâ&#x20AC;&#x2122;acqua, lascia intendere un passato semisepolto, sopito ma non spento. Nel variegato saliscendi collinare che connota Istanbul, la strada in trincea è marcata ai lati da due muri laterali non privi di una loro dignitĂ . A questo si accompagna una scalinata ben disegnata nella sua spazialitĂ . Al di sopra dei muri, la continuitĂ dei percorsi nel verde è garantita da un ponte pedonale in calcestruzzo, di non recente realizzazione, e che non fa bella mostra di sè. I
suoi evidenti segni di degrado materico e strutturale ne fanno certamente presagire una vita non lunga. Ă&#x2C6; chiara dunque la necessitĂ di una sua sostituzione a breve, cogliendo anche lâ&#x20AC;&#x2122;occasione per disegnare un brandello di luogo, re-identificarne la qualitĂ e farne un nuovo punto di accumulazione. Nasce cosĂŹ lâ&#x20AC;&#x2122;idea di spiccare un volo leonardesco tra le due sponde. Tracciare un vero e proprio cammino sullâ&#x20AC;&#x2122;aria. Definire una sinuositĂ verticale che, nellâ&#x20AC;&#x2122;attraversamento pedonale, emotivamente tende a spingerti verso il cielo per riportarti dolcemente verso il suolo. Un ponte che senti tuo, nel percorrerlo lambendone le arcate lignee fluttuanti tra le due parti ora riconnesse. In legno è anche la pavimentazione. Un leggero saliscendi ti incuriosisce non poco. Tra i due archi un percorso verde da forma alla continuitĂ spaziale del parco. Ecco dunque che il luogo ridiventa se stesso con piena e compiuta naturalezza. Ad un tempo ti senti allâ&#x20AC;&#x2122;aria aperta cosĂŹ come, altresĂŹ, nellâ&#x20AC;&#x2122;intimitĂ di casa propria. Lo scopo è raggiunto. Una piena riappropriazione del parco verso i suoi non effimeri utenti. Il verde stesso che mantiene la sua continuitĂ anche â&#x20AC;&#x2DC;sullâ&#x20AC;&#x2122;ariaâ&#x20AC;&#x2122; ti da unâ&#x20AC;&#x2122;ulteriore misura dellâ&#x20AC;&#x2122;attenzione ad un paesaggio ri-scoperto nel suo umanesimo. Il percorso non piĂš frettoloso è lâ&#x20AC;&#x2122;occasione per rallentare il passo. Vedere, fermarsi, guardare, osservare. Dal dettaglio allâ&#x20AC;&#x2122;insieme. Non si è piĂš soli. La sosta porta al pensare. Un nuovo, inatteso incontro induce al discor-
rere anche tra sconosciuti. Nuove amicizie. Nuove fratellanze. Nuove condivisioni. Nuovi amori. La vita continua ora migliore di prima perchè percepita e vissuta. Tutto questo sarĂ , forse già è. Non improbabile sogno, ma vera e propria realtĂ . GiĂ si può immaginare come e quando tutto questo vivrĂ . GiĂ si intravvede anche chi lo farĂ vivere. Il ponte non piĂš oggetto staticamente immobile, ma soggetto dinamicamente vibrante per le suggestioni che sarĂ capace di trasmettere a chi saprĂ e vorrĂ cogliere il vero senso dellâ&#x20AC;&#x2122;essere. E se il â&#x20AC;&#x2DC;dentroâ&#x20AC;&#x2122; lo vivi nella sua piena intimitĂ , non da meno il â&#x20AC;&#x2DC;fuoriâ&#x20AC;&#x2122; saprĂ parlare direttamente al cuore. Nel suo dialogo continuo con la storia di questo luogo, anche il torrino di pietra oggi rivive se stesso. Sentinella attenta nel vigilare che il brutto non prevarichi il bello e lâ&#x20AC;&#x2122;incultura dellâ&#x20AC;&#x2122;oggi non sia nebbia per coprire la cultura di ieri acciochè il domani sia perseguito per la centralitĂ dellâ&#x20AC;&#x2122;homo sapiens e non per la violenza dellâ&#x20AC;&#x2122;homo homini lupus. Per questo, da tempo, io stesso amo ripetere, anche a me stesso, che il â&#x20AC;&#x2DC;pontificareâ&#x20AC;&#x2122; deve essere considerato un vero e proprio privilegio dellâ&#x20AC;&#x2122;Uomo volto ad amare, amarsi, vivere e viversi. CosicchĂŠ, non sembra inutile affermare che Mimar Sinan cosĂŹ come Leonardo e lo stesso Michelangelo hanno qui, come altrove, lasciato il loro segno! Lâ&#x20AC;&#x2122;architettura dei ponti è simbolo di Vita nella storia dellâ&#x20AC;&#x2122;UmanitĂ .

MAP-21, lezione americana per pianificare lo sviluppo delle reti infrastrutturali di trasporto Approvato il piano Obama 2013-2014: 105 miliardi di dollari per iniziative mirate e programmate Sarebbe stato un bel motto per il nostro Govererno Tecnico e sarebbe piĂš che valido anche per i futuri governi. Purtroppo non siamo noi italiani a essere chiamati in causa. Ă&#x2C6; stato infatti il Presidente Barack Obama degli Stati Uniti a trasformare in legge, nel luglio 2012, il programma â&#x20AC;&#x153;Moving ahead for progress in the 21st Centuryâ&#x20AC;? (MAP-21), ovvero â&#x20AC;&#x153;Andiamo avanti con il progresso nel 21° Secoloâ&#x20AC;?. Il finan-ziamento è di 105 miliardi di dollari per gli anni 2013 e 2014. MAP-21 rappresenta una pietra miliare per lâ&#x20AC;&#x2122;economia USA. Oltre a prevedere i fondi necessari, infatti, definisce le politiche ed il quadro programmatico per investimenti destinati allo sviluppo e alla crescita di infrastrutture vitali per il Paese. Qualche decennio fa, il programma SHRP (Strategic Highway Research Program) recepito dal mondo intero, gettò le basi per il moderno sviluppo delle tecnologie stradali. Oggi MAP-21 crea un programma, multimodale e prestazionale, in grado di affrontare con decisione le varie sfide che interessano il sistema dei trasporti nazionale. Tali sfide riguardano lâ&#x20AC;&#x2122;aumento della sicurezza, la manutenzione delle infrastrutture (onde conservarne il valore), la riduzione della congestione del traffico, le migliorie al sistema dei trasporti, la protezione dellâ&#x20AC;&#x2122;ambiente, la riduzione dei tempi di esecuzione delle opere. Ă&#x2C6; previsto che lâ&#x20AC;&#x2122;Amministrazione Centrale (Federal Highway Administration, FHWA) lavori a stretto contatto con gli stakeholder per aiutare le comunitĂ locali a costruire progetti sostenibili e multimodali: dalle strade alle ferrovie, dalle ciclabili alla viabilitĂ cittadina. Per le strade, il programma comprende i seguenti temi principali: â&#x20AC;˘ espansione del sistema autostradale onde incorporare ar-
terie ter prima non incluse, con investimenti anche superiori a quelli destinati alla manutenzione; â&#x20AC;˘ creazione di un sistema di gestione prestazionale, per un piĂš efficace impiego dei fondi FHWA; â&#x20AC;˘ aiuti allo sviluppo, con creazione di posti di lavoro: autorizzati fondi federali per 82 miliardi di dollari, per strade, ponti, ciclabili, eccetera: ce â&#x20AC;˘ incentivazione degli investimenti privati; â&#x20AC;˘ raddoppio dei fondi per la sicurezza delle infrastrutture; â&#x20AC;˘ semplificazione dei programmi esistenti, mediante riduzione del numero dei progetti di base e incremento della loro importanza; â&#x20AC;˘ promozione dellâ&#x20AC;&#x2122;innovazione e accelerazione nella consegna dei progetti previsti. Il motto â&#x20AC;&#x153;Avanti per la strada giustaâ&#x20AC;?, coniato per Asphaltica 2012, non era poi tanto fuori luogo, visto che su questa linea altri Paesi si stanno muovendo. PiĂš volte abbiamo lamentato la mancanza di una politica di manutenzione e conserva-
zione del nostro importante patrimonio stradale, il cui valore si sta perdendo anno dopo anno. Ora dovremo attendere di nuovo tutti i rituali della politica per poi arrivare non si sa dove, mentre lâ&#x20AC;&#x2122;America, anche in questo campo, resta sempre piĂš lontana. (CG).

Interventi su strada, progetti ferroviari e applicazioni aeroportuali: un know how consolidato in materia di campagne con rilievi laser Dalle infrastrutture viarie alle ferrovie, dai progetti aeroportuali ai monitoraggi ambientali. Sono numerosi i campi di intervento della tecnologia di rilievo laser, in cui Sineco (Gruppo Sina) - che parteciperĂ al Viatec di Bolzano (21-23 febbraio) - vanta una notevole esperienza e specializzazione. Di seguito, presentiamo alcune referenze, ambito per ambito, particolarmente significative.
Settore stradale e autostradale Tra le varie esperienze applicative nel settore delle infrastrutture viarie, ricordiamo il rilievo geometrico laser mediante Lynx Mobile Mapper (per un approfondimento su questa specifica tecnologia si rimanda anche al volume â&#x20AC;&#x153;Appunti di viaggio nella Storia. Il rilievo laser Lynxde dellâ&#x20AC;&#x2122;Appia Anticaâ&#x20AC;?, un progetto Sina-Sineco realizzato dalla Casa Editrice la fiaccola, Milano, 2010) delle carreggiate autostradali in gestione al Gruppo Ecorodovias (Brasile) effettuato per le concessionarie del gruppo. I tronchi autostradali oggetto del rilievo ad alto rendimento con tecnologia Lynx Mobile Mapper si sviluppano per un totale di circa 1.700 km lungo il territorio degli stati Rio Grande Do Sul, ParanĂ e San Paolo e sono gestite dalle societĂ Ecopistas, per un totale
di 237,4 km, Ecovias, per un totale di 351,2 km, Ecosul, per un totale di 313,6 km, Ecovia, per un totale di 355,4 km ed Ecocatratas, per un totale di 449,2 km. Nellâ&#x20AC;&#x2122;aprile 2012 sono state avviate le attivitĂ di rilievo che si sono sviluppate in due fasi successive e regolarmente concluse nellâ&#x20AC;&#x2122;arco di sei settimane. Contestualmente alle attivitĂ di campo, sono state avviate le elaborazioni dei dati acquisiti sia direttamente in loco per la validazione sia presso la sede di Tortona per la fase di post process e restituzione.

Progetti in campo ferroviario Un caso significativo in questo ambito riguarda la gestione di tunnel ferroviari e torna a mettere al centro della scena i rilievi tramite Tunnel Scanner System, tecnologia impiegata sulla sulla linea â&#x20AC;&#x153;Porrettanaâ&#x20AC;? Bologna-Pistoia. Sineco ha eseguito per RFI, Compartimento di Bologna, i rilievi lungo la linea ferroviaria â&#x20AC;&#x153;Porretanaâ&#x20AC;? Bologna-Pistoia (tratta Pracchia-Marzabotto) di 25 gallerie ferroviarie per un totale di 8.475 m. Per ogni galleria sono stati acquisiti i dati fotografici (rilievo visivo), termografici (rilievo termografico) e geometrico (rilievo profilometrico). Lâ&#x20AC;&#x2122;acquisizione dei dati, per la ricostruzione dellâ&#x20AC;&#x2122;immagine fotografica dellâ&#x20AC;&#x2122;interno delle gal-

lerie, è stata eseguita con risoluzione pari a 5000 pixel per giro; tale risoluzione ha consentito di visualizzare ogni minimo particolare sia del rivestimento come dei servizi installati.
Ambito aeroportuale In questo caso segnaliamo due case history. La prima è stata presentata anche nel corso di un workshop ad Asphaltica 2012 e ha riguardato il rilievo geometrico laser mediante Lynx Mobile Mapper della pista di volo dell’aeroporto di Milano Malpensa (cliente Impresa Bacchi). Sineco ha eseguito il rilievo della pista di volo RWY 17L/35R al fine di supportare e ottimizzare il progetto costruttivo degli interventi di riqualifica dell’infrastruttura di volo. Oltre alla velocità di esecuzione del rilievo laser rispetto a quello eseguito con metodologia tradizionale, i dati acquisiti hanno consentito di estrarre le curve di livello, i profili, le dimensioni e le volume-
17 trie dell’intera superficie pavimentata della pista. La seconda riguarda la misura del degrado superficiale delle pista di volo principale dell’aeroporto di Venezia (cliente SAVE Aeroporto di Venezia). Oggetto dello studio è stata la pavimentazione della pista di volo principale RWY 04-22, dell’Aeroporto Marco Polo di Venezia, dallo sviluppo lineare complessivo di circa 3.250 m, tramite il LRIS (Laser Road Imaging System). L’innovativa strumentazione ha reso possibile, operando in orario notturno e in tempi ristretti, rilevare immagini ad alta definizione della superficie delle pavimentazioni, dalle quali individuare e misurare direttamente il “cracking” e le diverse tipologie di ammaloramento presenti, rendendo così oggettivo e razionale il calcolo dell’indice PCI (Pavement Condition Index) di cui alla norma ASTM D 5340-03. Le immagini, unitamente alle altre caratteristiche funzionali, si prestano grazie alla loro georeferenziazione a essere
oggetto di confronto tra rilievi a diverse cadenze temporali, nonché ad una gestione informatizzata mediante l’uso dei più diffusi strumenti GIS ed applicazioni sw (ArcUtilities Airport).
Monitoraggio ambientale Sineco è stata incaricata da Metro Engineering (Mi) del monitoraggio dei lavori di scavo e movimentazione terre previsti per la realizzazione della “BreBeMi”. L’attività, svolta tramite rilievi laser scanner dinamici con strumentazione Lynx, è finalizzata al controllo dei volumi di materiale estratti dalle cave autorizzate e utilizzati per la realizzazione del nuovo corpo stradale. L’applicazione nel settore ambientale della tecnologia Lynx Mobile Mapper identifica, con misure accurate e ripetibili, l’utilizzo di eventuali materiali non autorizzati o non idonei, consentendo di effettuare in maniera rapida e affidabile un vero e proprio bilancio delle terre. 14.

Bitumi modificati di alta qualitĂ e avanzate soluzioni per bitumi tradizionali: cosĂŹ il numero uno dellâ&#x20AC;&#x2122;industria petrolifera russa si presenta al Belpaese Giovane, ma giĂ tra i leader. In patria ma non solo. In Italia, per esempio, ha giĂ un piede (sede legale) a Roma e un altro (stabilimento) a Bari, settore lubrificanti. Nel mondo, il suo nome ha le radici in Russia, per esempio sulle maglie dello Zenit San Pietroburgo allenata da Luciano Spalletti, e un braccio in Serbia, dove sponsorizza la Stella Rossa Belgrado, e possiede NIS (Nafta Industria Srbije), la compagnia petrolifera locale. Stiamo parlando di Gazprom Neft, la multinazionale petrolifera che il gruppo Gazprom 18 ha battezzato cosĂŹ nel 2005 acquisendo quasi il 76% di Sibneft e innovando una storia da quel momento decennale (1995, nascita della OJSC Siberian Oil Company). Oggi, nel settore bitumi la compagnia occupa il primo posto tra le VINK (le societĂ petrolifere verticalmente integrate) e in Russia una tonnellata di bitume su tre si produce negli impianti di Gazprom Neft. Tra i suoi progetti: consolidare la propria posizione sul mercato internazionale. Nel novembre scorso, il gruppo ha partecipato per la prima volta a una fiera del Belpaese, ad Asphaltica. leStrade, a Padova, ha avuto lâ&#x20AC;&#x2122;opportunitĂ di intervistare Dmitriy Orlov, manager Gazprom Neft a capo del Dipartimento Bitume. leStrade. Può spiegarci le ragioni della vostra partecipazione a una fiera di settore italiana come Asphaltica? Orlov. Siamo qui per manifestare il nostro interesse ad attivare sinergie con i partner italiani; con alcuni di loro, peraltro, giĂ cooperiamo con soddisfazione reciproca: per esempio, con la societĂ Massenza, che ha giocato un ruolo determinante nellâ&#x20AC;&#x2122;organizzazione della produzione di bitumi modificati in Russia, a Omsk. A Padova abbiamo inteso avviare contatti con le piĂš importanti imprese di costruzioni stradali italiane, con i produttori dei componenti per la modifica dei bitumi (polimeri SBS), i produttori di bitumi, RMV ed emulsioni. Sicuramente, pensiamo che Asphaltica sia unâ&#x20AC;&#x2122;ottima manifestazione per la dimostrazione delle migliori realizzazioni nel settore e che lâ&#x20AC;&#x2122;esperienza avuta in questa fiera sia risultata molto utile. Siamo venuti qui per presentare la nostra azienda: Gazprom Neft è oggi una delle piĂš importanti societĂ petrolifere ver-
ticalmente integrate in Russia. I suoi principali poli produttivi petrolchimici si trovano a Mosca, Yaroslavl e Omsk, oltre agli stabilimenti a Panchevo e Novi Sad (Repubblica Serbia, raffineria NIS). leStrade. Come descriverebbe i vostri principali punti di forza, anche in chiave concorrenziale, sul mercato della produzione bitumi? Orlov. Gazprom Neft è unâ&#x20AC;&#x2122;azienda abbastanza giovane, ma con le tradizioni consolidate anche per quanto riguarda la produzione dei bitumi. Lo sviluppo dinamico è iniziato non piĂš di cinque anni fa quando abbiamo firmato un accordo di cooperazione con il Ministero dei trasporti russo nel settore delle costruzioni stradali, produzione e utilizzo dei bitumi nella Federazione Russa. Da allora, lavoriamo costantemente sul miglioramento della qualitĂ dei materiali bituminosi e sullâ&#x20AC;&#x2122;ampliamento del nostro assortimento di marca. CosĂŹ in Russia siamo stati tra i primi a lavorare sulla modifica dei bitumi, allestando la produzione dei bitumi modificati con polimeri. Oggi, quellâ&#x20AC;&#x2122;unitĂ produttiva, inaugurata nel 2010, viaggia a pieno regime e produce soluzioni di estrema qualitĂ . Anche a Mosca e a Panchevo produciamo bitume modificato per i clienti del Distretto Centrale Federale della Federazione Russa, della Serbia e per lâ&#x20AC;&#x2122;esportazione. Tuttavia dialogando con i clienti, abbiamo capito che il materiale bituminoso tradizionalmente di stagione - viene richiesto anche nel periodo invernale. Gli

operatori del settore stradale sono pronti a creare riserve, e noi, grazie allâ&#x20AC;&#x2122;uso della tecnologia dellâ&#x20AC;&#x2122;imballaggio del bitume nei clovertainer - speciali cube container - possiamo garantire la qualitĂ intatta del prodotto durante il lungo trasporto e lo stoccaggio, con indubbi benefici per le attivitĂ di trasporto dei materiali bituminosi nelle zone con difficile accesso. leStrade. Pensa che questo esempio di soluzione tecnica possa avere successo anche in Italia? Orlov. SĂŹ. Il nostro approccio si basa non solo sulla soddisfazione delle imprese di costruzioni stradali per quanto riguarda i prodotti standard, che rispondono cioè alle specifiche russe (GOST), ma anche sul piano della ricerca di soluzioni che soddisfano esigenze particolari. Andiamo sempre incontro alle esigenze dei nostri clienti e cerchiamo ogni volta di alzare il livello e raggiungere i nuovi limiti.

La sicurezza nel mondo dei conglomerati Scopo del manuale è la comprensione e la diffusione, a tutti i livelli e negli specifici luoghi di lavoro, della cultura della sicurezza, basata sulla prevenzione. Per far ciò si è partiti dallâ&#x20AC;&#x2122;esplorazione del Testo Unico sulla Sicurezza (D.Lgs. 81/2008) e dalla conseguente analisi, mettendo in evidenza alcuni concetti fondamentali quali la valutazione dei rischi, le misure di prevenzione, le informazioni, la sorveglianza sanitaria, la consultazione e la partecipazione. Il tutto con riferimento specifico alla produzione e stesa del conglomerato bituminoso. Un approfondimento tematico, che spazia dagli aspetti tecnici alla medicina sul lavoro, completa il testo al fine di fornire un quadro completo di analisi e risposte allâ&#x20AC;&#x2122;intero settore. I primi commenti pervenuti sono stati tutti positivi: gli ambiti per la consulta-
zione sono molteplici e tutti adeguatamente approfonditi ed esaustivi. Per gli interessati il rimando è alla sezione Manuali del nostro sito www.siteb.it dalla quale è possibile anche sfogliare alcune sezioni del nuovo volume della collana editoriale di SITEB.
