introduction Box Section Specifications concrete pipe Precast reinforced concrete box sections are designed in accordance with ASTM C1433 - Standard Specification for Precast Reinforced Concrete Monolithic Box Sections for Culverts, Storm Drains, and Sewer. Design for other load specifications such as Cooper E-Series for railway loading and box jacking can also be accommodated to meet specific project requirements. The scopes of nationally accepted specifications for precast concrete box sections are highlighted in this section for reference. • ASTM C 1433 - Precast Reinforced Concrete Monolithic Box Sections for Culverts, Storm Drains, and Sewers. Covers single-cell precast reinforced concrete box sections cast monolithically and intended to be used for the construction of culverts and for the conveyance of storm water industrial wastes and sewages. ASCE 26-97 - Standard Practice for Direct Design of Buried Precast Concrete Box Sections: Covers the direct design of buried one-cell precast reinforced concrete box sections installed in accordance with the requirements outlined in the Practice, intended for the conveyance of sewage, industrial wastes, and to serve as tunnels. stormwater treatment technologies • box sections It is important to note that at a span measuring three meters or greater, box sections are considered a bridge and must adhere to the design requirements of the Canadian Highway Bridge Design Code. manhole and catch basin material LAFARGE PIPE eMANUAL PAGE 5
