With that growth comes the need for increased wastewater treatment capacity. However, the county’s treatment plant, at only 6.5 million gallons per day (mgd), relies on older technology and sits adjacent to an elementary school and sensitive residential area. Therefore, the county has teamed with CDM to design and build a state-of-the-art, 10-mgd facility on land the county leases from the U.S. Air Force. In addition to featuring biological nutrient removal and ultraviolet disinfection, the new Arbennie Pritchett water reclamation facility will incorporate 4D design, which integrates a database into the 3D facility model, providing a consistent and lasting platform for efficient operations and maintenance (O&M). The new reclamation facility will support continued resource conservation and economic development in this vibrant coastal community. Located along the coast of Florida’s panhandle, Okaloosa County is growing. CDM’s approach to 3D design involves all disciplines—architectural, electrical, HVAC, plumbing, structural, and others—in the creation and maintenance of the physical 3D model. “We naturally think in 3D, and this really facilitates the communication process. Each discipline team is capable of visualizing and cross-checking work in real time during the design phase. This allows the team to resolve details and connections that otherwise may have had to be addressed at greater expense in the field,” explained David W. Kozan, P.E., CDM resident engineer. Enhancing the Design-Build Process The project incorporates the intelligent process and instrumentation diagram (P&ID) as the single source of data from which the design of the facility is developed. The intelligent P&ID is the layout of the process within the plant, essentially showing how the plant will function. All of the major process lines, valves, and instrumentation used to control the plant are detailed in the diagrams. “The use of these advanced technologies allows us to produce more complex designs faster and more efficiently than the traditional two-dimensional approach,” noted Raymond P. Kearney, CDM lead 3D/4D modeler. 11 3
