For this metals and mining client, ITAC evaluated multiple options for replacement of two 11.5’ diameter 800’ long underground tunnel reclaim systems that have been in service for over 45 years. The study involved all disciplines including civil, structural, mechanical, process, electrical and instrumentation. ITAC worked closely with the client to evaluate the total installed capital cost, operational and maintenance cost coupled with operational costs impacts associated with the installation schedules of each of the different options. ITAC leveraged construction expertise to evaluate and compile construction cost, constructability and overall project schedule. A detailed and report and estimate was provided for five different concepts, plus various options. ITAC delivered a very thorough FEL2 Report and Estimate that was completed on a tight schedule.
