The Construction Phase of a SCADA project includes software development, RTU layout and fabrication, equipment procurement, physical construction, testing, and commissioning. Erecting the Monopole in LihueFor Kauai, the construction phase began in January 2003 and ended with final system acceptance in November 2005. The project had a construction budget of $4,500,000. The successfully contractor/integrator was award the project at $4,499,471. During construction, the owner added $285,618 in additional scope, including adding sites that were not in the original project, resulting in a final cost of $4,785,089. The project had multiple delivery dates throughout the various phases, and all work was completed on time or early. The project was substantially complete and KDOW was given full use of the SCADA system on July 5, 2005, the date the Availability Test Phase of the project began. The system passed the Availability Test on October 4, 2005, and after final punch list completion, the project was accepted in November 2005.
Because Kauai is distant from Timberline's home and from the System Integrator's facility, Timberline required that the contractor build "one of each" RTU type and hold for inspection before installing additional cabinets. That gave Timberline a chance to make a hold point inspection trip to the island. During that trip, one of 20 during the course of the project, Timberline noted variations between the project requirements, as shown on the project specifications and drawings and explained to the contractor what needed to be corrected for the project to be acceptable. Timberline has found that hold point inspections like these greatly reduce project risk by eliminating the chance that dozens of sites will be installed "wrong" and have to be reworked.
In the end, the SCADA system was completed on schedule and under budget and the resulting project was a huge success.
