How to examine brickwork in a wall

After completion of brickworks, it is required to examine the brickworks with the following four steps:
• Gauge - Examine the height of the course
• Level – Ensure that the perfect level is maintained for course 
• Plumb – Ensure that the wall is vertical
• Straight - Ensure the wall is straight

These examination works should be initiated while each course is placed and in this order to certify that the previous checks remain unaffected.
Gauge: While going to develop any wall, it's required to retain the courses at the corners at the equivalent height with the help of a gauge board.
Demarcate a piece of timber with marks similar to gaping of one brick height as well as the density of the bed joint (generally a total of 75cm).
Utilize the rod at the corner when each course starts and verify that it maintains the exact height, on uneven ground, begin by providing a datum peg next to the wall in order that the gauge rod is place smoothly.
Level: To maintain the exact level of the course, apply a spirit level. As the corner bricks are arranged to the proper height, so any modification is made by accomodating the bricks in from the corner. Bricks are not developed with very tight tolerances. Therefore, just level the portions of the bricks which connect the base of the spirit level.

Plumb: Verify that the wall face is vertical with the use of a spirit level, tap the brick over the wall as required to modify the brick as per requirement. It should not be done for both sides of the wall, select one side as 'the face' and just plumb that side. Perform it along the wall, placing the points roughly just under the length of the spirit level.
Examine both sides of corners.
Straight: Apply a straight edge among the points which are plumed earlier to straighten the course. Tap the bricks as required.
Similar to plumbing the wall, only examine the face of the wall without straightening both sides.
It is not possible that the straight edge will connect every brick over its whole face, attempt to have the centre of each brick to connect the straight edge and the two ends of the brick approximately positioned from it correspondingly.
