21. QUALITY OBSERVATIONS PODIUM

22. WEST SIDE FOOTING CONCRETE WASTAGE DUE TO FOOTING PASCHAL SHUTTERING BULGED

25. GOOD PRACTICES

26. CONCRETE CASTING DATES MENTION WITH STENCIL SHEET

27. After slab concrete Constructed curing ponds and maintain curing continuously.

28. AFTER SLAB CONCRETING FINISHING SHOULD BE DONE WITH POWER TROWEL

29. WALLS CURING SHOULD BE DONE WITH WATER SPRINKLER

30. After slab concrete Placed Hessain cloths and maintain curing continuously. Due to summer heat increased curing time.

31. During s lab concrete, Slab levels checked by level gauge rod .

32. During concrete work boom head cover with bag to overcome falling of concrete while boom shifting to one place to another place

33. BEFORE START PUMPING OF CONCRETE BOOM HEAD SHIFT TO OUTER OF SLAB AREA FOR PUMP SLURRY WATER(HI PUMP PRIME ) TO OUTSIDE OF SLAB.

34. During wall concrete continuous Rubber Hammer Malleting doing for avoid air gaps

35. DURING AND AFTER CONCRETEING CURING DONE ON PANELS FOR DECREASING HEAT

36. Apply shuttering oil to Mivan Panels with rollers before Panels fixing .

37. PROVIDED SHEARKEYS IN WALLS FOR BONDING TO FRESH CONCRETE

38. PROVIDED WOODEN STOPPERS BEFORE SLAB CONCRETE CASTING

39. APPLY NITO BOND SBR FOR BONDING PURPOSE IN BETWEEN FRESH AND EXISTING CONCRERE BEFORE CONCRETE POURING

40. MENTIONED PROPER NUMBERING ON MIVAN PANELS

41. PLACEING OF STEEL IN SAFE MANNER ON CONCRETE SLEEPERS

42. Slump at RMC Plant Slump at Site Checked the slump of Every RMC Vehicle in plant and Site.

43. Before setting out of concrete surface make BROOMING finishing being ensured to avoid cracks.

44. BAD PRACTICES

45. AFTER WORK COMPLETION BLOCK ENGINEERINGS ARE NOT KEPT COVER BLOCKS IN SAFE MANNER COLLECTED THE COVER BLOCKS AND HANDOVER IN STORE

46. COLLECTED THE STUB PIN AND HANDOVER IN STORE

47. AFTER CURING POND CONSTRUCTED STEEL RODS PLACED ON AND BROKEN IT, SO THAT CURING NOT PROPERLY HAPPEN

48. FOR VERTICAL REINFORCEMENT BARS MASTER RING NOT PROVIDE AT 1M LEVEL FROM SLAB

49. MINOR CRACKS ARE DEVELOPED IN PLASTERING DUE TO CURING NOT DONE PROPERLY AFTER PLASTERING DONE

50. 3.PMC/CLIENT MAJOR REPEATED COMMENTS

51. Wall and slab junction area binding wire not Properly tying. Cover blocks not properly provided. Spacing not maintain properly in reinforcement. Cleaning not done properly. Vertical lapping length of bars not maintain properly. Master rings not provided.
