Section 1711 - Reinforcing Steel and Post-Tensioning in Concrete Construction
Current through Register 2024 Notice Reg. No. 38, September 20, 2024
(a) Scope and Application.
NOTE 1: Additional requirements for reinforcing steel and concrete construction are contained in Article 20 and Article 29 of these Orders.
NOTE 2: Other relevant provisions in the GISO and CSO may apply to concrete and masonry construction operations.
(b) Definitions.
Competent Person. One who is capable of identifying existing and predictable hazards in the surroundings or working conditions that are unsanitary or dangerous to employees, and who has authorization to take prompt corrective measures to eliminate them.
Controlling Contractor. A prime contractor, general contractor, construction manager, or any other legal entity that has the overall responsibility for the construction of the project, including planning, quality, and completion.
Dead Load. A constant load, without load factors, due to the mass (weight) of members, the supported structure and permanent attachments or accessories.
Falsework. Formwork to support concrete and placing operations for supported slabs of concrete structures, including all supporting members, hardware, and bracing.
Formwork. The total system of support for freshly placed or partially cured concrete, including the mold or sheathing (form) that is in contact with the concrete, as well as all supporting members, including shores, reshores, hardware, and braces.
Post-tensioning Operations. A method of stressing reinforced concrete in which tendons running through the concrete are tensioned after the concrete has hardened.
Qualified Person, Attendant, or Operator. A person designated by the employer who by reason of training, experience, or instruction has demonstrated the ability to safely perform all assigned duties and, when required, is properly licensed in accordance with federal, state, or local laws and regulations.
Qualified Rigger. A rigger who meets the criteria for a qualified person.
Reinforced Concrete. A composite material in which the concrete provides the material's compressive strength, while the reinforcing in the form of additional embedded material provides the tensile strength and/or ductility.
Reinforcing Ironworker. A worker primarily engaged in the hoisting, rigging, field fabrication, moving, and installation of reinforcing steel assemblies, members, post-tensioning cables, and related equipment. Reinforcing steel activities include, but are not limited to: off-loading and material handling of reinforcing components; fabrication, pre-assembly, and placement of reinforcing steel columns, beams, joists, mats, welded wire mesh, and curtain-walls; and the placement of post-tensioning cables.
Reinforcing Steel Assemblies. Vertical and horizontal columns, caissons, walls, drilled piers, mats, and other similar structures. For purposes of this standard, reinforcing steel includes rods, bars, or mesh made from composite and/or other materials.
Reshores. The temporary vertical supporting members that are placed or left in place when the original supporting shores or posts for the formwork are removed. The reshores are used to support partially cured concrete and other construction loads.
Slip Form. A form that is moved as concrete is placed and slides without being detached to form walls or other concrete structures.
Stressing Jacks. Portable hydraulic devices that pull the tendons associated with post-tensioning concrete to create a permanent tension load.
Tendon. A metal element, usually of steel such as wire, stranded components (such as wires), bars or rods used in pre-stressing or post-tensioning concrete.
(c) Site Access and Layout. The controlling contractor shall ensure that the following is provided and maintained:
EXCEPTION: This requirement does not apply to roads outside of the construction site.
EXCEPTION: 1: Where, the design, structure, or space constraint precludes the installation of exterior platforms.
EXCEPTION: 2: Where the design of the structure allows for the safe landing of materials without the exterior platform.
(d) Written Notifications Prior to Commencement of and Immediately Following Reinforcing Steel Installation and Concrete Placement.
The controlling contractor shall ensure that the reinforcing steel contractor on the project is provided with the following written notifications at the times indicated:
(e) Stability Requirements for Vertical and Horizontal Columns, Walls, and Other Reinforcing Assemblies.
(f) Requirements for Impalement Protection and Custody of Protective Covers.
NOTE: to subsection (f)(2)(A) through (C): The responsibilities of the controlling contractor related to accepting the control and custody of protective covers does not relieve the individual employer or subcontractor from protecting their employees from impalement hazards in accordance with the provisions of Section 1712(c).
(g) Requirements for Hoisting and Rigging Reinforcement Assemblies.
(h) Post-tensioning Operations. The controlling contractor shall:
EXCEPTION: to subsection (h)(5): Where the adjoining structure or other structural space constraint precludes the installation of exterior platforms.
(i) Fall Protection.
Employees shall not be permitted to place or tie reinforcing steel in walls, piers, columns, etc., more than 6 feet above an adjacent surface, unless a personal fall protection system is used in accordance with Section 1670 or other method affording equivalent protection from the hazard of falls from elevated surfaces.
EXCEPTION: : Reinforcing ironworkers may travel point-to-point horizontally or vertically on reinforcing steel up to 24 feet above the surface below providing there are no impalement hazards.
(j) Formwork and falsework stability shall be provided in accordance with Sections 1713 and 1717.
(k) Training Requirements. In addition to the training requirements of Section 1509, the Injury and Illness Prevention Program, employers shall ensure that each employee who performs reinforcing steel and/or post-tensioning activities has been provided training by a qualified person in the following areas for the activities in which they are engaged:
1. Renumbering from Section 1712 filed 11-1-73; effective thirtieth day thereafter (Register 73, No. 44).
2. New NOTE filed 6-21-85; effective thirtieth day thereafter (Register 85, No. 25).
3. Repealer and new section filed 10-26-2017; operative 1-1-2018 (Register 2017, No. 43).
