Introduction to Training Organization Detail information on the Project Training Experiences Problem encountered ………. ……….. ……….
Central Engineering Consultancy Bureau (CECB) is the largest engineering consultancy organization in Sri Lanka. CECB offer multi-disciplinary expertise such as Building constructions, Roads, Highways, Bridges and Irrigational works. Nearly 600 of engineers, architects and geologists are employed under CECB. They are doing multi billion rupee projects which makes them large profit margins.

Soil was filled layer by layer and water was sprinkled to bring the moisture content of the soil to the optimum moisture content. Soil was compacted using Vibratory Roller. Sand Cone test was done to determine to dry unit weight of the soil Performed Sand cone Test
This is done as a protection against termite attack. Drill holes at 2 to 3 feet intervals along the perimeter of the building. Inject the termiticide. Then termiticide spray directly to the soil. Inject termiticide Spraying termiticide
Water Supply Line 20mm, 25mm, 32mm, 40mm PVC pipes are used. Pipe lines are checked by applying pressure of 8 bars. Sewer Line Sewer lines are laid 1:80 slope. All sewer lines are connected to manhole. Applying Pressure for Supply lines
