Challenge
Value engineering
Solution
EIC Activities reviewed the project’s rock quality assessment, temporary tunnel support design and the proposed drill and blast tunnelling methodology. Improvements to the drill and blast methodology were identified in overbreak allowances, blasting pull efficiency, sequencing and ventilation – increasing savings and mitigating risk.
