About this file
This document contains technical provisions for reinforcing steel requirements on a federal construction project for Tesuque Lagoon Improvements managed by the Department of Health and Human Services Indian Health Service. The technical provisions specify that reinforcing steel must meet ASTM standards for grade and material quality. Reinforcing steel must be placed accurately according to design drawings and secured in position to prevent displacement during concrete placement. Cutting, bending and installation of reinforcing steel must follow American Concrete Institute standards. Reinforcing steel will not be measured and paid for separately, but must be included in payment items for work requiring reinforcing such as cast-in-place concrete. Material certification test results for tensile and weld shear properties are required to be submitted for the proposed reinforcing steel.

TECHNICAL PROVISIONS
SECTION 03 - REINFORCING STEEL
TP-301 SCOPE:
Furnish all labor, materials, equipment, and incidentals as required and perform all operations in connection with the placement of reinforcing steel and wire fabric reinforcing, complete, in strict accordance with the applicable drawings and these specifications.
TP-302 MATERIAL:
Reinforcing bars shall meet the requirements of the Standard Specifications for Billet-Steel Bar
(intermediate grade) for Concrete Reinforcement, ASTM A615. Welded wire mesh shall meet the requirements of the Standard Specifications for welded Steel Wire Fabric for Concrete
Reinforcement, ASTM A185.
The use of cold twisted bars will not be permitted. Wire fabric shall be used only when specified and shall be the type shown on the drawings and approved by the Owner or Owner’s Representative.
TP-303 METHOD OF CONSTRUCTION:
When placed, all reinforcement shall be free from dirt, oil, paint, grease, mill scale, loose or thick rust. When bending is required, it shall be accurately done without the use of heat, and bars having cracks or splits at the bends shall be rejected. All reinforcement shall be placed in the exact position shown on the drawings, and shall be securely held in position by wiring to, and blocking from, the forms, and by wiring together at intersections, such that it will not be displaced during depositing and compacting of concrete. Precast concrete blocks, plastic chairs or metal chairs shall be used for supports where applicable. Rock supports will not be allowed.
Placing and fastening of reinforcement in each section of the work shall be approved by the Owner or Owner’s Representative before any concrete is deposited in the section. Cutting and bending, placement, handling and storage, and installation of reinforcement shall be in accordance with
American Concrete Institution (ACI) standards.
TP-304 MEASUREMENT AND PAYMENT:
Reinforcing steel shall not be measured and paid separately. Rather they shall be included in the unit or lump sum bid prices of those items shown on the Bid Schedule that require the inclusion of reinforcing steel, even if not specifically mentioned within the measurement and payment sections of those particular pay items.
