  12. 12. 3.2PROCESS OF LAYING A SLAB: In this all the sophisticated equipments are used to finish the work in easy andsimple method. The thickness of each slab is 20cm and between 2 wings a strip is not castedimmediately but casted after 25 days known as Expansion strip. The steel rods used inconstruction are THERMAX STEEL from Germany. Also shaft spaces are provided in slab for plumbing work Figure 3.4, 3.5 views of shafts on and below the surface of the slab Figure 3.6, 3.7 describes work of electrical conduting and cup locks support After framing using shutter boards filmed with shuttering oil, electricalconduting will be done, here cup locks are used to support the frame, and then concrete ispoured over the frame with the help of hydraulic jack and concrete pipes which are used topump the concrete from transit mixer to the place where slab has to be laid. To preventcoagulation inside pipes, first a cream slurry cement paste has to be passed through pipes forsmooth flow of concrete 12
  13. 13. Tower cranes are used to move the required material from one place to other insite both vertically and horizontally. The tower cranes can with held the wind force up toheight of 30m, beyond which they need to be clamped to nearby column of building forsupport.Each tower crane costs about Rs.95 lakhs Figure3.8 view of the tower crane from the site office3.3BATCHING PLANT:M40 concrete mix is used here for the construction of structure. A separate batching plant ispresent near the site for the construction of lake verandahs and hill crest structures. Figure 3.9 batching plant with a transit mixer 13
  14. 14. Figure 3.10, 3.11 describes the control panel and closer look to batching plant respectively. A Transit mixer is used to transfer concrete from batching plant to the work site.It carries around 7cubic mtr volume of concrete and takes about 15 min to load.The main components of batching plant are Control panel Silos Cement storage godown Small tower crane for pushing ingredients into mix using trayThe batching plant consists of silos which are used to store flyash and chemicals accelerators and retarders.

  17. 17. Figure 3.16, 3.17 describes frame work for column concreting and tor rings respectively. Columns are laid under utmost care. steel rods are firmly placed and theseare connected using different types of TOR RINGS with the help of binding wire. About 8Tor rings are provided at spacing in every column. Basically tor rings are of different typeslike rectangular, square type, triangular, trapezoidal used for connecting various amount ofsteel rods.tie rod, ropes are used to place the shutters firmly around the column where theconcrete is to be laid. Once the shutter is firmly placed then the concrete is filled manually till0.5 mtr in order to avoid HONEY COMBING. M40 grade concrete is used for layingcolumns. The date on which concreting is done to a column is written on column so that carehas to be taken to cure it for 14 days 17
  18. 18. Figure3.18 the checklist for column concreting Prior to concreting of a column it should fulfil all the requirements of thechecklist for the column concreting ,it checks all the activities and should meet theacceptance criteria after checking the report will be signed by Foreman, Site engineer andSector engineer before giving a nod to concreting 18

Various safety measures have been taken as shown below Figure 3.23, 3.24 represents the view of safety nets tied around the building edges Figure 3.25 the following items are provided as per ISO safety norms. 22
  23. 23. CHAPTER 4 CONCLUSIONS From the field study report, it is evident that the construction is going on full swing, butfrom according to the project monitoring chart, the project is lagging behind the schedule fora period of about 6 months. As dated on 1st june2012 the construction for slab for 3th floor is going on and stillabout 24 floors are to be constructed. The schedule to hand over the project is dated forJanuary, 2014 at the earliest. To accomplish this task the work should be done in 2 batches of workforce throughoutthe day and the developers should lend more financial support than present. Gracing the Hulimavu Lake, this most happening realty destination for the elite will bea self-sufficient and all encompassing community where its residents will prosper forever. 23
