Osterman has pushed the boundaries of whats possible in close proximity drill & blast. Its was evident to us at an early stage that we needed to lead by example. Osterman does not only design and manage drill & blast operations, we carry out the whole charging and firing process. Most of our consultants/engineers are also shotfirers, spending most of their time on sites executing their own blast designs. We believe this leads to the best designs and outcomes. Osterman has been in charge of carrying out the design and execution of blasting operations on a number of high profile, state significant projects in Brisbane and Sydney.
