2. Erect a double scaffolding without making a hole in the wall (Or erect a single standing scaffolding by taking support of wall as directed by the higher authority).
3. Fill the external gaps on the side in masonry & beam or column joints with rich mortar and complete the socketing work.
4. Fix 6” wide chicken mesh on the joint of RCC & Masonry wall (Nailing of chicken mesh should be at a distance of 230mm interval).
5. Take the plumb or line from top to bottom at all the edges to ensure the accuracy and keep the thickness of the single coat plaster at minimum 10-12mm uniformly.
