Hydraulic ram pumps and Sling Pumps

Cement bricksBurned clay bricks also possible if according to standard specification. Table 9 shows the number ofbricks for wall height 3.52 m. This is equivalent to construction height of 3.60 m which includes theheight of the roof slab. The wall of 3.52 m must be made of 44 courses, based on a brick size of 70mm and 10-mm joint. This shows the number of bricks needed is 5960, that will be 6000 bricks.BRC welded meshThe quality definition 6" x 6" mesh No. 65 or 66 in rolls or sheets. Table 11 last column underinternal diameter 5.30 m shows 74 m² for ground and roof slab reinforcement.Reinforcement rods 20 mm ØThis is the major reinforcement of the ring foundation. The amount needed is shown in Table 12,being 134 metre run. The next column indicates the distribution which is shown in drawing No. 1 forthis diameter, the number being seven.In addition 20-mm rods are used for the lintel reinforcement. Table 13 provides the information incolumn six = 25.00 m which has to be added to the 134.0 m and entered in the schedule.Reinforcement rods 10 mm ØIt is assumed that rods of 8 mm Øare available and therefore 10-mm rods are only to be used wherethis diameter is needed. Table 11 indicates the amount for the vertical wall reinforcement,distribution shown in drawing No 2. The Table shows under construction height 3.60 m and internaldiameter 5.30 m an amount of 66.0 m.Reinforcement rods 8 mm ØTo be used as horizontal wall reinforcement shown in drawing No. 4. Table 12 shows the amount ofsteel in columns two, three and four. The construction height of 3.60 m has to be provided with 14ring reinforcements. For this 256 m are needed.In addition the stirrups for the ring foundation are of the same diameter and have to be added. InTable 12 the last two columns show the amount = 85.0 m and the number of stirrups = 56. The 85.0m have to be added to the 256 m and to be indicated in the schedule of material.Reinforcement rods 6 mm ØThis is needed for stirrups of the lintel reinforcement cage only. If this dimension is not available,8-mm rods can also be used. In this case the amount has to be added to the previous figures. Table13 in column seven indicates the amount of 32.0 m and in column eight the number of stirrups to bebent.After the amount of major building material has been indicated in the schedule, it is recommendedthat the different prices be investigated. The more suppliers asked to give their rates, the better. Itcan be experienced that prices differ from item to item, and it might therefore be appropriate to orderfrom different suppliers.Example 2A large reservoir of 152 m³ capacity is to be tendered. According to Table 5 this reservoir aconstruction height of 3.45 m. For the process of tendering all information is provided in Chapter 6.2.To make use of the Bill of Quantities, it is necessary to find the quantities in the different tables andfill them in on the form.75
