STOCKHOLM | PROJECT
working space is narrow and being cautious with noise, vibrations etc. is an absolute requirement. For Itinera, it has been helped to work with a company familiar with the local conditions. Underground, despite the somewhat diverse nature
of the rock quality encountered, so far Itinera has experienced minimal difficulties from equipment failing and production stoppages. Sandvik’s machines have performed reliably to ensure uninterrupted progress with the project’s time-critical nature. Gustaf Marelius, Block Manager, Rock at Itinera, says:
“We can’t afford to stand still; any production stoppages are out of the question. Time is the most valuable asset we have here.” Itinera’s rental agreement with Sandvik includes a
fleet of machines that comprises – in total for the two tunnel projects: four DT1132i 3-boom rigs, with one dedicated to long-hole stope handling for injection drilling; three DT923i 2-boom rigs; and, a Commando DC300Ri surface rig for smaller tasks. The selection of these machines was to ensure maximum capacity within the limited workspace available. The agreement also includes the Sandvik Rod Handler
system (SRH) for automated grouting, and the iSURE® (Intelligent Sandvik Underground Rock Excavation) software, designed specifically for optimising drilling and blasting cycles through the generation of comprehensive data. Erik Lundén, Measurement Engineer at Itinera, says:
“I use iSURE® daily as I create all the drilling plans and transfer them to the drilling rig.” Under the agreement, proactive support on-site includes a spare parts inventory – rods, bits, and
casings, among other RD535 30kW drifters, Sandvik Alpha 360 Rock Tools, and GT38 rods – to help minimise downtime. Sandvik’s technicians, working alongside Itinera’s team, can then promptly address any equipment issues, preventing significant stoppages and keeping the project on track. Mathias Stubbans, Workshop Manager at Itinera,
says: “We have a good dialogue with Sandvik’s service technicians; we have follow-up meetings every week.” Consolidating the supply of drilling rigs, rods, and
steel has enabled Itinera to benefit from streamlined communication and ease of management. With everything centralised through the all-inclusive approach with Sandvik, any issues arising can be promptly addressed. The consequent simplicity and efficiency lets Itinera focus on its core competencies, while Sandvik’s technicians work on-site full-time, closely collaborating. It is felt this integrated approach facilitates seamless
communication, and so strengthens relationships and enables effective problem-solving. Regular follow-up meetings enhance dialogue and enable both teams to address concerns promptly. Sven Kvick, Operator at Itinera, says: “I like the
simplicity; there aren’t many concerns.” This rental approach, combined with a
comprehensive parts and service agreement, proved to be the most advantageous option for Itinera, allowing for accurate forecast of costs and helping to eliminate uncertainties associated with depreciation of purchased equipment. At the completion of the project, Itinera returns the rented machines to Sandvik. They will be available for future projects.
