Construction of a pre-engineered structure such as steel structure is a challenging work. It requires the full attention of qualified staff. It also needs a qualified QAQC Engineer to inspect the work of a construction team to ensure that the completed work is fully compliant with the project requirement.
One of the most challenging jobs in the construction of steel structure is the installation of anchor bolts where it is considered to be an ankle joint of a steel column. A method statement of the installation of anchor bolt should be developed to make sure that the process is true against the approved drawing and the most important, it should be within the safe working condition.
Here is the method statement for installation of anchor bolts.
