CGA Engineers, as the civil consultant to Selser Schaefer Architects, designed the Cherokee Nation Food Distribution Facility in Collinsville, Oklahoma. CGA provided the civil design documents as well as the civil construction administration.
One of the more interesting parts of the project was the utility design. After identifying the utilities marked by the Oklahoma One Call Center, CGA concluded additional research into sewer and gas services would be required.
Though a sewer system was in the area, it was determined that the elevation would not allow a working connection with out a lift to pump the sewer into the system. A cost analysis was performed evaluating three options. Option one was to install a small package lift station to get the sewer into the nearby system maintained by the City of Collinsville. Option two was to gravity feed to the south and tie into the Collinsville system with a new sewer interceptor. Option three was to treat the sewer on site. Bot options one and two were ruled too expensive in either initial cost or in life cycle maintenance cost. Thus, the decision was made to treat the sewer on site. Several options were evaluated including lagoons, aerobic treatment, and a septic system. After evaluating the pros and cons of each design alternative, a septic system with a designated lateral field was selected.
A similar issue was found in the investigation of getting natural gas to the site. On this site, there was no immediate service. The only two options were to extend ONG service from the south for approximately 2,000 feet or use propane. After review of the life cycle cost, a propane tank was installed.
Being a Food Distribution Center, part of the design included a truck loading dock. Give the heavy traffic load, the pavement was changed to concrete from asphalt for the loading dock. The rest of the pavement for parking was asphalt with gravel parking area for overflow.
