1.1.13. Before laying tiles obtain approval of setting out by consultant.
1.1.14. Provide symmetry about center lines of the space or areas and adjust to minimize tile cutting.
1.1.15. Tiling should be started from the start point as fixed on the approved shop drawings.
1.1.16. Lay out tile work so that tiles less than 1/2 full size do not occur and with the minimum of cutting. Carefully grind the edges of the cut tile. Make sure that the cut tiles are in corners and are equal accordingly on each wall face.

1.8.10. Surplus material shall be removed with a dry cloth.
1.8.11. Control Joints
1.8.12. Provide Control Joints 6 millimeters minimum width in large tile areas at a maximum of 4.5 meters in each direction and at the perimeter walls. Do not saw-cut joints after installing tiles.
