Infinity served as the prime consultant for the design of the capacity expansion to the Ollie Pump Station in Jesuit Bend, Louisiana. As the prime consultant, Infinity provided civil, structural, mechanical, electrical engineering design, and construction administration.
The Ollie Pump Station provides storm drainage across approximately seven (7) miles encompassing about 3000 acres of Plaquemines Parish’s West Bank. Infinity performed a drainage study of the basin and the subsequent addition of two (2) new 300 CFS drainage pumps to the existing 60-year-old facility. The increased capacity accommodated an expanding population and the replacement of aging equipment. Infinity’s expansion designs included:
•New, pile-supported pump building foundation
•Upgrades to existing pump house with a steel frame, hurricane-resistant building
•Enlarging the existing suction and discharge basins to accommodate the new pumps and flow rate and modifying existing pumps and deteriorated supports
•Specifying new pumps, diesel engines, and gears based on the hydraulic requirements, including future Corps of Engineers levee modifications
•Specifying compressed air and diesel fuel piping and storage utilities
•New operator quiet room with office and restroom facility
•New electrical power and lighting for station modifications
•New automatic transfer switch for an existing generator
•All components to maintain operability of the station during construction
Additionally, the project included permit drawings as required to apply for a U.S. Army Corps of Engineers Section 10/404 permit; topographic and hydrographic surveys of the suction and discharge basins; a geotechnical survey of the site with soil borings. Infinity also designed the replacement of the retaining walls to connect to the existing levee. Infinity also provided construction administration and on-site inspection services for this $16,500,000 project.
