I just finished quoting a project that was specified by Thorburn Associates. I am pleased at how much faster we can generate a complete, responsible quotation when the drawings and specifications are integrated. Your method forces the equipment list to match the design, and eliminates any confusion when preparing a bid. We can actually build the project from your drawings. That serves to keep our total costs down and makes it much easier to provide a finished system that works the way the client wanted. This is especially true on fast track projects. Thank you for making drawings and specs that are more than “conceptual”.
