| Facility Dynamics has developed a software application named CACEA to accurately estimate the costs of DDC systems. The application consists of multiple vendor's list price information and third party providers of ancillary devices, sensors, actuators and valves. Systems and subsystems are built-up and controls devices and components are assigned to the systems. Detailed cost information is associated with various components. Details include wire length, time to do the individual tasks such as start-up, calibration and installation of each DDC component and device. Overall system operating software set-up is also included. These tasks include graphic page creation, trending set-up, report set-up and configuration of the various system components. This level of detail has allowed us to sit down with the prospective DDC vendor with as much and usually more detail than he/she has typically prepared. Recently, we applied this cost estimating tool to a large new project where the preliminary estimates provided by the sole source vendor was over $4 million. After preparing the detailed cost estimate, the final price was below $3 million. |
