Abstract: Duke Power Company is building a partially precast-prestressed concrete intake structure at an estimated savings of 36% of the cost of a traditional poured-in-place reinforced concrete intake structure. The structure is a combination of precast concrete columns, precast-prestressed concrete wall panels, structural steel beams and bracing, and poured-in-place concrete slabs. The structure is designed to meet certain loading conditions and hydraulic criteria and has been model tested to insure satisfactory pump performance. In addition, the structure has almost the same degree-of-freedom from underwater maintenance as a poured-in-place reinforced concrete intake structure.
