H. BRICK MASONARY WORK

31. For Brick Masonry work, Unless otherwise specified, mortar for brick work shall be composed of 1 part of cement to 6 parts of approved sand for walls of one brick thick (25 cm) and over and 1 part of cement to 4 parts of approved sand for half brick thick and brick on edge walls.

32. All brick shall be immersed in water for 24 hours before being put into work so that they will be saturated and will not absorb water from the mortar.

33. The bricks shall be laid in mortar to line, level and shapes shown on the plan, slightly pressed and thoroughly bedded in mortar and all joints shall be properly flushed and packed with mortar so that they will be completely filled with mortar and no hollows left anywhere. The verticality of the walls and horizontality of the courses shall be checked very often with plumb bob and spirit level respectively.

34. Joints shall not exceed 10 mm (about 3/8") in thickness and this thickness shall be uniform throughout. The joints shall be raked out not less than 10mm (about 3/l8") deep when the mortar is green where pointing is to be done. When the brick surface are to be plastered, the joints shall be raked to a depth of 5 mm when the mortar is green, so as to provide good key to plaster.

35. All brick works shall be kept well watered for l4 days after laying. While pozzalana cement is used for mortar the curing shall be extended by one week at contractor’s expense.

I. HOLD FAST FOR DOOR FRAMES

All dust and oily matter, if any, shall be brushed and cleaned and surface to be plastered shall be kept wet for 6 hours before plastering is commenced.

39. Ceiling plaster shall be completed before commencement of wall plaster. Plastering shall be started from the top and worked down towards the floor. All putlog holes shall be properly filled in advance of the plastering as the scaffolding is being taken down. To ensure even thickness and a true surface, plaster about 15 × 15 cm shall be first applied, horizontally and vertically, at not more than 2 metres intervals over the entire surface to serve as gauges. The surfaces of these gauged areas shall be truly in the plane of the finished plaster surface. The mortar shall then be laid on the wall, between the gauges with trowel. The mortar shall be applied in a uniform surface slightly more than the specified thickness. This shall be brought to a true surface, by working a wooden straight edge reaching across the gauges, with small upward and sideways movements at a time. Finally the surface shall be finished off true with trowel or wooden float according as a smooth or a sandy granular texture is required. All corners, arises, angles and junctions shall be truly vertical or horizontal as the case may be and shall be carefully finished. Rounding or chamfering corners, arises, provision of grooves at junctions etc. where required shall be done without any extra payment. Such rounding, chamfering or grooving shall be carried out with proper templates or battens to the sizes required.

40. When suspending work at the end of the day, the plaster shall be left, cut clean to line both horizontally and vertically. When recommencing the plastering, the edge of the old work shall be scrapped cleaned and wetted with cement slurry before plaster is applied to the adjacent areas, to enable the two to properly join together. Plastering work shall be closed at the end of the day on the body of wall and not nearer than 15 cm to any corners or arises. It shall not be closed on the body of the features such as plasters, bands and cornices, nor at the corners of arises. Horizontal joints in plaster work shall not also occur on parapet tops and copings as these invariably lead to leakages. The plastering and finishing shall be completed within half an hour of adding water to the dry mortar.

41. Curing shall be started as soon as the plaster has hardened sufficiently not to be damaged when watered. The plaster shall be kept wet for a period of at least 7 days. During this period, it shall be suitably protected from all damages at the contractor’s expense by such means as the Engineer-in-Charge may approve. The dates on which the plastering is done shall be legibly marked on the various sections plastered so that curing for the specified period thereafter can be watched.

42. The plaster shall be finished to a true and plumb surface and to the proper degree of smoothness as required. The work shall be tested frequently as the work proceeds with a true straight edge not less than 2.5 m long and with plumb bobs. All horizontal lines and

Multibuild Consultants, Vapi

Page 6 of 7

surfaces shall be tested with a level and all jambs and corners with a plumb bob as the work proceeds.

43. Any cracks which appear in the surface and all portions which sound hollow when tapped, or are found to be soft or otherwise defective, shall be cut out in rectangular shape and redone as directed by the Engineer-in-Charge.

44. External plaster of 20mm thick shall in two coats. Generally coarse sand shall be used for the under coat and fine sand for the finishing coat. The plaster shall be applied in two coats i.e. 12 mm under coat and then 8 mm finishing coat and shall have an average total thickness of not less than 20 mm. The finishing coat shall be applied after the under coat has sufficiently set but not dried and in any case within 48 hours.

K. WATER PROFFING OVER ROOF & SUNKEN SLAB

45. Before taking up the water proofing work the construction of parapet walls, including finishing should be completed. Similarly, the ancillary items like fixing up of all down take pipes, water pipes and electric conduits etc. should be completed and no such work should be allowed on the area to be treated during the progress of water proofing treatment or even later.

46. The surface of the slab should be roughened by scrapping when the slab concrete is still green, however, the surface need not be hacked. In case the slab is already cast and surface fairly finished, the same shall be cleaned neatly of all mortar droppings, loose materials etc. with brooms/cloth.

47. Providing and Laying of Slurry under Base Coat - The quantity of water required to prepare the slurry with 2.75 kg. of blended cement + water proofing compound as per manufacturer specification to be painted over an area of 1 sq m. Depending upon the area of surface that has to be covered, the required quantity of slurry should be prepared using 2.75 kg. blended cement + water per sq. m. area to be covered, taking particular care to see that only that much quantity of slurry shall be prepared which can be used within half an hour of preparation i.e. before the initial setting time of cement. The prepared slurry shall be applied over the dampened surface with brushes very carefully, including the joints between the floor slab and the parapet wall, holes on the surfaces, joints of pipes, masonry/concrete etc. The application of the slurry should continue up to a height of 300 mm on the parapet wall. Slurry should also be applied up to a height of 150 mm over pipe projections etc.

48. Laying Base Coat 20 mm thick - Immediately after the application of slurry and when the application is still green, 20 mm thick cement plaster as base coat with cement mortar 1:5 (1 blended cement: 5 coarse sand) shall be evenly applied over the concrete surface taking particular care to see that all the corners and joints are properly packed and the application of the base coat shall be continued up to a height of 300 mm over the parapet wall.

49. Laying Brick Bat Coba - Brick bat of size 25 mm to 115 mm out of well burnt bricks shall be used for the purpose of brick bat coba. The brick bats shall be properly dampened for six hours before laying. Brick bats shall be laid to required slope/gradient over the base coat of mortar leaving 15-25 mm gap between two bats. Cement mortar 1:5 (1 blended cement: 5 coarse sand) shall be poured over the brick bats and joints filled properly. Under no circumstances dry brick bats should be laid over the base coat. The haunches/vata at the junction of parapet wall and the roof shall be formed only with brick bat coba. In case the brick bat coba is laid on the base coat immediately on initial set there will be no necessity of applying cement slurry over the base coat before laying the brick bat coba. However, if the brick bat coba is to be laid on the subsequent day, cement slurry prepared as described above shall be applied over the top surface of the base coat, and then only the brick bat coba shall be laid.

50. After two days of curing of brick bat coba cement slurry prepared as applied in 1st layer shall be applied on the surface of brick bat coba The application of slurry shall be the same as

Multibuild Consultants, Vapi

Page 7 of 7

described above which should cover the haunches/vata, and the remaining small portion of parapet wall and also inside the groove of parapet wall. Immediately on applying the cement slurry over the surface of the brick bat coba and when the slurry applied is still green, the fibre glass cloth shall be spread evenly on the surface without any kink & pressed to see that no air spaces exist. 20 mm thick layer of cement plaster, without leaving any joints shall be applied with cement mortar 1:4 (1 blended cement: 4 coarse sand) over the entire fibre glass cloth including the haunches/vata and the small portion on the parapet wall. The surface of the finishing layer (protective coat) shall be neatly finished with cement slurry prepared as mentioned above. The finished surface shall be allowed to dry.

51. The entire surface thus treated shall be flooded with water by making kiaries with weak cement mortar, for a minimum period of two weeks.
