The transitional intermittency was investigated in zero pressure gradient boundary layers developing on plate covered with sand paper (grits 60). The free stream mean velocity was 5 m/s and the free stream turbulence level was either natural 0.3 percent or it was risen up to 3 percent by means of two squared mesh plane grids generating the dissipation lenth parameter 3.8 mm or 33.4 mm respectively. The results are compared with those received in the smooth wall boundary layer
