5. PROJECT DETAILS PHASE 3 PHASE 2 PHASE 1

6. Setting Out of Staircase Flight and Landing Going (280mm) Thickness of the Flight Rise (165 mm) Staircase Beam Staircase Flight

7. Preparation of Stair-case Doing Setting Out of Staircase Flight Formwork of Staircase Flight

8. Soil Compaction • 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

9. Termite Treatment • 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. Spraying termiticide Inject termiticide

10. Plumbing Work 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

11. PROBLEMS & SOLUTIONS ON CONCRETE STRUCTURES Hydration temperature increment in mass concrete structures THERMOCOUPLE WITH DATA LOGGER THERMOCOUPLE LOCATIONS

12. ADD FLY ASH SOLUTION

13. Concrete Defects AFTER BEFORE SOLUTION BARA MORTAR

14. SAFETY MANAGEMENT • Provide Safety Equipments (helmets, safety shoes,boots,googles, gloves and safety belts) • Safety Instruction Boards • Located Medical Centre at the Site • Special Traffic Controlling Section • Charge Fairs from employees for Misbehaviors

15. Training Experience as a whole • Not only improved the technical knowledge as I discussed. • Obtained a vast knowledge on dealing with all sorts of people • Learned both contractor and consultant point of view when constructing a new building. • Made new friends with industry engineers and other workers. • Say any other activities involved during training period…
