1. As see in the picture above brick perps are exceeding the required 15 mm width or height tolerance. (Having even perps aids the plaster to grip the walls and lasts longer.)
2. Brick perps have not been pushed back or racked. (This also helps the plaster to grip.)
3. Mortar missing.
4. As seen in the picture above some of the perps are in excess of 30 mm.
5. This means that there is plaster attached to mortar instead of brick. We have seen this type of errors leading to walls cracking and plaster falling off.
6. As quality assurances professionals we have seen this error on many occasions, which lead to contractors breaking down and rebuilding walls.
7. Our clients has also experienced walls and plaster cracking after 2 to 3 years because of these poor construction methods. Often the contractors who have built these walls have subsequently closed down, which means that our clients had to pay for repairs and remedial work. This is an extra cost to the client and it affects the staff as they often have to relocate while the repairs are being completed.
8. We have experienced professionals that works with laborer's on avoid these errors.
9. Our checklist can be use to help all members on the team to be educated and thus prevent these errors from occurring.
