The actual Masons training and the interaction with the masons started in this week. The programme starts with the screening the masons to access their knowledge in the construction activities. The selected trainees are then registered. The icebreaker session is conducted with the selected trainees, which serves as a platform for experience sharing. The masons are trained on basic site selection procedure. The class on site selection procedures is a prelude to the behavioral pattern of the structural components with respect to disasters.
A theory class is taken on various types of soil and their behavior. This study is undertaken to help the masons choose the type of foundation to be done for that particular type of soil. The masons are trained in the construction of Stub foundation with anchorages. As the foundation works are going on they are given tips on bar-bending on how to minimize the wastage and to improve the strength of the rod work. The grade beam is completed during this week.

Week 3

During the third week the super structure is completed, i.e the brick work from the grade beam to the casting of the filler slab. The brickwork from the grade beam to the Damp proofing course (DPC) is done in English bond and a layer of header course is done above the DPC. The Rat trap bond is done from the header course above the DPC to the roof with two-header courses, one running just below the filler slab and the other running below the lintel level.
