tensile properties and the wire fabric also for weld shear strength. No steel reinforcement shall be used in the Works until the testing results have been approved by the Engineer. If ordered by the Engineer, test procedures shall be repeated at the Contractor's expense for any new supply of reinforcement dur- ing the course of the Works. 

All reinforcement shall be clean and free from pit corrosion, loose rust, mill scale, paint, oil, grease, adhering earth, or any other material that may impair the bond between the concrete and the rein- forcement or that which may cause corrosion of the reinforcement or may be detrimental to the quality of the concrete. 

Storage of reinforcement shall be on racks or supports clear of the ground. Different types and sizes of reinforcement shall be kept separate. 

## 6.2.2 Bending and cutting schedules 

The Contractor shall prepare for his own use bar bending schedules and bar lists, cutting schedules and sheet lists for wire fabrics for each individual structure from the information given in the approved working Drawings and in the herewith Employer’s Requirements, and shall be responsible for ensur- ing that correct information is given when ordering reinforcement. Copies of these schedules, lists and orders shall be submitted to the Engineer for his approval. Steel bar supports shall be included in the bending schedules. 

The approval of the bar bending and cutting schedules, lists and orders shall not relieve the Contractor of his responsibility to execute the reinforcement fixing in accordance with the Drawings and/or ac- cording to the requirements specified in TS 500 and the code for buildings to be built in disaster areas 2007. 

## 6.2.3 Protection and cleaning 

Reinforcement shall be protected at all times from damage, and when placed in the structure shall be free from dirt, loose mill scale, rust scale, paint, oil or other foreign substance. All reinforcing steel shall be carefully cleaned of all set or partially set concrete, shutter oil or paint which may have been deposited during the construction of adjacent works. 

## 6.2.4 Bending of bars 

Steel reinforcement shall be cut from straight bars free from kinks and bends or other damage and shall be bent cold by experienced competent workmen. Bars of diameter greater than 12 mm shall be bent in a bending machine designed for the purpose and approved by the Engineer. Any reinforcing bar that has already been bent shall not be re-bent at the place of the previous bend. 

## 6.2.5 Cutting of wire fabrics 

Wire fabric reinforcement shall be cut straight from the sheets. The use of off-cuts in the Works will not be permitted. 

## 6.2.6 Lapping of bars and wire fabrics 

Lapping bars and wire fabrics shall be permitted when necessary and approved by the Engineer. No welding of reinforcement shall be carried out. 

Unless otherwise specified, lap length of bars shall be at least fifty (50) times the diameter of the larg- er bar, and laps shall be positioned in a staggered pattern. 

Laps on adjacent section of wire fabrics shall generally be carried out as follows:
