Session One Handout

Pdf Summary

This document discusses special inspections and training for precast concrete structures. It covers various topics such as code requirements, types of precast concrete structures and components, general overview of precast concrete manufacturing, documents required for inspections, condition assessment of precast components, erection of precast structures, and preparation of cast-in-place concrete foundations. The document also highlights the qualifications required for special inspectors and the inspection of fabricators.<br /><br />It further explores the common types of precast concrete structures including parking garages, schools, office buildings, correctional facilities, storage & distribution facilities, industrial/manufacturing facilities, multi-unit residential structures, mixed-use structures, and stadiums/arenas.<br /><br />The document also provides information on commonly used precast concrete components such as double tees, beams, columns, spandrels, wall panels, stair units, flat slabs, hollow-core slabs, and architectural cladding components.<br /><br />Additionally, it discusses fabrication methods for precast concrete components and the plant certification program by PCI (Precast/Prestressed Concrete Institute).<br /><br />The document explains reinforcing methods for precast components and the role of prestressing in precast concrete applications. It outlines how reinforcing and prestressing work in precast components and the effects of loading on precast beams.<br /><br />Furthermore, the document emphasizes the required inspections and documents for effective inspections, the importance of adherence to erection tolerances, and the assessment of precast components for condition, cracks, spalls, and stability.<br /><br />The document concludes with a brief overview of double tees and the PCI Journal article on fabrication and shipment cracks in prestressed hollow-core slabs and double tees.
