CHAPTER 3 DETAILS OF FIELD STUDY

3.1DETAILS OF STRUCTURE:

1. The height of the structure is 99.5mts.2. The structure consists of 2 wings (wing-A and wing-B). 3. Two wings are separated by an inaccessible partition wall in every floor throughout the structure.4. Each wing consists of 4 flats in each floor totalling 8 flats per floor. 5. The lake verandahs consist of 27 floors totalling 216 flats in them. 6. Apart from the 27 floors there are 2 subsurface floors designed for parking purpose. 7. These subsurface floors are well protected by retaining walls with height varying from 8-12m .8. A stilt lobby level is also provided.9. Each wing consists of 4 lift wells and 2 stair cases

3.2PROCESS OF LAYING A SLAB: In this all the sophisticated equipments are used to finish the work in easy and simple method. The thickness of each slab is 20cm and between 2 wings a strip is not casted immediately but casted after 25 days known as Expansion strip. The steel rods used in construction 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, electrical conduting will be done, here cup locks are used to support the frame, and then concrete is poured over the frame with the help of hydraulic jack and concrete pipes which are used to pump the concrete from transit mixer to the place where slab has to be laid. To prevent coagulation inside pipes, first a cream slurry cement paste has to be passed through pipes for smooth flow of concrete Tower cranes are used to move the required material from one place to other in site both vertically and horizontally. The tower cranes can with held the wind force up to height of 30m, beyond which they need to be clamped to nearby column of building for support.Each tower crane costs about Rs.95 lakhs Figure3.8 view of the tower crane from the site office

3.3BATCHING PLANT:M40 concrete mix is used here for the construction of structure. A separate batching plant is present near the site for the construction of lake verandahs and hill crest structures.

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.

3.4Q/A & Q/C LAB (Quality assurance &quality control lab): In this lab the quality and strength of various building materials like cement, sand, concrete, water, coarse aggregate are tested using various testing machines and apparatus like vicat apparatus, Compression testing machine flakiness and elongation index gauges, volume measuring jars digital weighing scale(20kg max. and 2gm accuracy) sample collecting trays pycnometer

3.5LAYING OF COLUMNS:

Figure 3.15 represents view of various columns from below ground surface

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 these are connected using different types of TOR RINGS with the help of binding wire. About 8 Tor rings are provided at spacing in every column. Basically tor rings are of different types like rectangular, square type, triangular, trapezoidal used for connecting various amount of steel rods.tie rod, ropes are used to place the shutters firmly around the column where the concrete is to be laid. Once the shutter is firmly placed then the concrete is filled manually till 0.5 mtr in order to avoid HONEY COMBING. M40 grade concrete is used for laying columns. The date on which concreting is done to a column is written on column so that care has to be taken to cure it for 14 days Figure3.18 the checklist for column concreting Prior to concreting of a column it should fulfil all the requirements of the checklist for the column concreting ,it checks all the activities and should meet the acceptance criteria after checking the report will be signed by Foreman, Site engineer and Sector engineer before giving a nod to concreting3.6MODEL FLAT:

3.8SAFETY: The company has observed various safety norms as per ISO standards and A safety office is present in the construction site. 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.

CHAPTER 4 CONCLUSIONS

From the field study report, it is evident that the construction is going on full swing, but from according to the project monitoring chart, the project is lagging behind the schedule for a period of about 6 months. As dated on 1st june2012 the construction for slab for 3th floor is going on and still about 24 floors are to be constructed. The schedule to hand over the project is dated for January, 2014 at the earliest. To accomplish this task the work should be done in 2 batches of workforce throughout the day and the developers should lend more financial support than present. Gracing the Hulimavu Lake, this most happening realty destination for the elite will be a self-sufficient and all encompassing community where its residents will prosper forever.
