They are very busy and their business is very good. What I value most is quality. Their production quality control is very strict, which can be seen from the quality control documents, procurement of raw materials records, procurement inspection records, each process inspection records, unqualified products processing, product liability processing, factory inspection records. I found the quality of both my own products and those they made for other customers to be very good.The purpose of this method statement is to lay down the systematic procedures for the various activities required for reinforcement bars to ensure that all works are carried out in accordance with the approved shop drawings and project specification.

This method statement covers the general procedures to be followed for installation of reinforcement bar for footing, strap beam, raft, slab and all structural concrete. Safety of the personnel and properties is to be given prime importance and all the works to be carried out without causing any accidents or property damages.

Reinforcing bars involves the following activities. Adequate access and egress should be provided to the site for work. All the personnel should wear basic personnel protective equipment. All the equipment, tools and tackles being used for the work should be in good working condition and maintained. All the personnel will be provided with toolbox talk on the procedures to execute the work safely. Below is the checklists which can be used for the inspection of reinforcement steel bars installation work for different areas as applicable.

Check any other MEP services to be installed are done as per approved shop drawings. Final Inspection Visual inspection after completion of rebar erection. Enter your email address:. Check setting out is done as per approved shop drawings. Check access permission ,equipment and scaffolding permission. Installation of rebar to be done as per approved drawings and BBS. Proper cover to be maintained using approved spacers and chairs.

Please check the following as per approved shop drawings: Dia.Reinforced concrete structures are designed to behave monolithically. Properly designed splices of individual reinforcing bars are a key element in transmitting forces through the structure and creating a load path.

A lap splice is the predominant method used for splicing reinforcing bars. Bars may be spaced apart or in contact. For lap splices, contact splices are preferred for the practical reason that, when wired together, they are more easily secured against displacement during concrete placement. Non-contact lap spliced bars should not be spaced too widely apart, permitting a zigzag crack in the concrete between bars. The length of a lap splice varies with concrete strength, type of concrete, the yield strength grade of the reinforcing bars, bar size, bar spacing, concrete cover, and the amount of ties or stirrups.

Lap splice lengths are always shown on placing drawings and will be found either in the details, lap charts, or in the general notes.

Additional information on lap splices can be found here. In general, CRSI recommends against manual arc welding in the field. However, if necessary, field-welded splices are accomplished by electric arc welding the reinforcing bars together.

For projects of all sizes, manual arc welding will usually be the most costly method, due to direct and indirect costs of proper inspection. While the welding code is a comprehensive document, other important items such as securing chemical analysis of the steel, field inspection, super-vision, and quality control are required for a project with welded reinforcement.

CRSI recommends against connecting crossbars by small arc welds, known as "tack welds. This is a mechanical splice that requires special bars with thread-like rolled, deformations over their entire length which meets ASTM A Splices are assembled with lock nuts and threaded couplers, then the nuts are tightened to a specified torque.

Alternatively, the lock nuts can be omitted when the bars can be torqued together. Special hardware permits use for end anchorages in concrete or connection to structural steel members. Bars may be flame or saw-cut.

This is a mechanical splice consisting of a coupler with internal straight threads at each end that joins two upset end reinforcing bars with matching external threads. Upsetting the bar ends permits the cross-sectional area in the threaded portion to be greater than the bar cross-sectional area.

This type of splice can either be in three pieces the two bar ends and internally threaded coupler or in two pieces with the coupler integrally forged or pre-assembled onto the bar end. These systems are also available as weld-on couplers, transitional couplers, positional couplers, and headed bars. This is a mechanical splice consisting of a coupler with internal straight threads at each end that joins two reinforcing bars with matching external threads.

Because the cutting of threads reduces the net cross-sectional area of the reinforcing bar, some manufacturers use bars one size larger while other manufacturers use bars with tensile and yield strengths sufficient to overcome the loss of net area by thread cutting.

This type of splice is in three pieces the two bar ends and the internally threaded coupler. These systems are also available as weld-on couplers, transitional couplers, and positional couplers.Cost Effectiveness The conventional method of connecting reinforcement bars with lap joints in reinforced concrete need not be always appropriate. Structural Reliability Coupler spliced perform like continuous reinforcement.

That develops full tensile strength mechanically, independent of concrete. Coupler splices are excellent for severe condition like earthquake, typhoon, especially suitable for condition that demands higher ductility of building structure.

It offers greater flexibility in design options. The simplicity in detailing of reinforcement, particularly in reinforcement congestion zones minimizes the reinforcement fixing errors, detailing and fixing of seismic reinforcement becomes effortless.

Workability with higher steel-to-concrete ratio allows optimum sizing of RC structural column. Fixing couplers requires no special skills or equipments. Simple mechanical ways in adopting mechanical splicing compared to lapping, accelerates construction schedules for optimum cost and efficiency.

It is economical to use couplers for higher diameter rebar as it saves on considerable weight and rebar wastage.
