Rally investigated five options as part of the scoping study, evaluating them based on technical merits and their ability to satisfy the project’s success criteria as defined by the Client. For all options, Rally was responsible for the HVAC design, gas detection, and lifesaving interlocks into the building’s existing control system, electrical power supply, mechanical piping, and civil / structural modifications as necessary.
Once a preferred option was selected, Rally prepared all preliminary documentation in support of the option for inclusion into the Scoping Study. This included equipment and instrument lists, roof assessment reports, and electrical load lists and single line diagrams.
A detailed capital cost estimate was prepared comparing three of the options deemed feasible to allow cost comparison of each. The estimate was built up using MTOs provided by the engineering disciplines and a Basis of Estimate was included.
