Trevi S.p.A.

The main goal of the grouting consolidation/curtain of the #RogunDam Project is to avoid the uncontrolled leakage from the reservoir through the rock mass foundations below the dam and the near surface zones exposed to very high hydraulic gradients. Each construction phase requires serious, disciplined, and organized work in a highly challenging context. #TreviSpa, with its own motivated and experienced site teams, is proceeding with the works in accordance with the work schedule and high quality plan required by the Sub-Contract. (The Project is commissioned by #OJSC Rogun HPP with Webuild as the Lot 2 Contractor responsible for the construction of the Rogun Dam).

We are thrilled to announce that Lorenzo Faedi, #Treviicos Senior Geotechnical Engineer - Technical Manager, will be presenting at the upcoming course on Grouting and Ground Improvement hosted by the Colorado School of Mines that will take place in Golden, CO, from July 29th to August 1st, 2024.   Lorenzo, with his extensive background and over a decade of experience in #groundEngineering, will delve into the intricacies of #JetGrouting and #DeepMixing Methods, including test sections, QC and practical applications in the field. His sessions, scheduled for July 30th and August 1st, will offer valuable insights and knowledge to industry professionals. ➡ Don’t miss this opportunity to learn more and to network with fellow professionals.!   For more information and to register for the course, please visit the School of Mines’ official website: https://lnkd.in/gXzFQc6P

The #ROGUNDam Project foresees 3 different types of drilling and injection activities within the Main Dam Grouting Galleries carried out by #TreviSpa: The preliminary consolidation around the galleries, the grout curtain (Sub Horizontal, Downwards, Upwards, Fan) and the drainage curtain of the Main Dam.. The grout curtain activities consist of the sequential execution of 3 grout curtain lines, namely the A line (on the downstream side), the Line B (on the upstream side) and the central Line C The primary holes will be drilled first, followed by the secondary and finalized by the tertiary grouting boreholes. The grouting evaluation will be based on the closure criteria and grout volume absorptions detected per each stage of each borehole. (The Project is commissioned by #OJSC Rogun HPP with Webuild as the Lot 2 Contractor responsible for the construction of the Rogun Dam).

#TreviSpa is using Soilmec (SM5E) electric rigs for the drilling works along the first level of Main Dam Grouting Galleries of #RogunDam Project. The reasons for choosing this type of rigs are their high maneuverability and mobility required to work within tunnels with small diameter. For the grouting activities, #Trevi is using the T-Grout software that could be easily managed and allowes automatic injection. It aims to provide all the operative parameters, technical information, and results required for high-efficiency control of the injection operations.. The T-Grout software has been successfully tested in other important Hydro Power Projects carried out by Trevi. (The Project is commissioned by #OJSC Rogun HPP, and Webuild is the Lot 2 Contractor responsible for the construction of the Rogun Dam.)

As far as the works to be carried out by #TreviSpa for the #ROGUNdam are concerned, the sub-contract is divided into two main phases: ➡ the first one, completed in 2023, consisted of the consolidation of the rock mass #foundation of the Main Dam core, beneath the so-called RCC Pad; ➡ the second one, consists of the #Drilling & #Grouting activities for the consolidation, grout and drainage curtain within the existing Main Dam Grouting Galleries. (The Project is commissioned by #OJSC Rogun HPP and Webuild is the Lot 2 Contractor responsible for the construction of the Rogun Dam.)

The contract for the consolidation and waterproofing of the rock mass foundations of the #RogunDam in Tajikistan was awarded in May 2022 to #TreviSpa, the specialized foundation and consolidation division of the Trevi Group, by the main Contractor of Rogun HPP Project Lot 2 #Webuild S.p.A. The Rogun Dam, consisting of the construction of a 335 m high embankment #dam, will be the highest dam in the World. Once completed, the Rogun Hydro Power Project will be made by 6 turbines in operation 600 MW each, for a total installed capacity of 3 600 MW, able to double the energy potential of the whole country, making Tajikistan a reference point for the energy sector of the Central Asia.

Last tuesday, #TreviASC, the #TreviSpa branch for #foundation and #geotechnicalWorks in the Kingdom of Saudi Arabia, in the presence of Giuseppe Caselli, CEO of the Trevi Group and Andrea Acerbi, General Manager of the Trevi Spa division, started the production piling activities for the #AmiralProject, a petrochemical complex which represents an investment of $11 billion, located in Al-Jubail Industrial City (Jubail-II), Kingdom of Saudi Arabia (KSA). TreviASC is a sub-contractor of TECNIMONT, the Italian Group international leader in the field of #plantEngineering. Trevi ASC's scope of work for the Amiral project, consists in approx. 2,000 piles in #CFA diameter ranging between 600mm and 800mm with depth ranging between 10 to 20 meters approx. 5 Piling rigs are engaged for the execution of Trevi Asc works.

Galataport İstanbul è il grandioso complesso costruito nel porto turco che ha ridato vita ad un fronte mare rimasto inutilizzato per circa 200 anni. Sviluppato dalla società terminalistica che è parte del gruppo Dogus e costato 1,7 miliardi di dollari, ha visto #TreviSpa, leader globale nella costruzione di porti, banchine e pontili, sia nei panni di appaltatore principale che come designer delle proposte per tutti i lavori di ingegneria geotecnica. #Trevi, che ha completato con successo tutte le attività previste tra il 2016 e il 2019, ha impiegato più di 270 persone e 20 impianti di perforazione, eseguendo contemporaneamente più di 13 diverse tecnologie di fondazione, che coprono quasi tutte le applicazioni dell’#ingegneriaGeotecnica finora conosciute. #GalataportIstanbul, per cui è stata prestata anche grande attenzione rispetto all'impatto ambientale, è in grado di accogliere contemporaneamente 3 navi da crociera, comprese quelle di classe Oasis della Royal Caribbean, le più grandi del mondo, per un movimento di 15.000 passeggeri al giorno e ospitare il primo terminal sotterraneo di 29.000 metri quadri.

Today Lorenzo Faedi , Senior Geotechnical Engineer - Technical Manager at #Treviicos, will partecipate at the #InternationalGrouting Deep Foundations Institute webinar. Lorenzo will delve into the world of #JetGrouting, sharing real case applications from projects like NEBT, SREL C4, and Drammen. These examples will illustrate how Jet Grouting technology is put into practice, complementing the theoretical insights provided by other speakers.
