WEBVTT Kind: captions Language: en 00:00:19.060 --> 00:00:28.320 Hello, last day we discuss the technology systems and it is role to deliver mass housing 00:00:28.320 --> 00:00:36.230 in India, we have discussed that the conversational technology is unable to deliver housing for 00:00:36.230 --> 00:00:39.350 the mass in quicker time. 00:00:39.350 --> 00:00:45.280 So there are alternative options faster technologies are available, which can deliver housing in 00:00:45.280 --> 00:00:54.290 a quicker time and we also attempted to see the it is characteristics typologies of the 00:00:54.290 --> 00:00:57.890 technology systems and what are the options for India. 00:00:57.890 --> 00:01:05.250 So today we will see the examples and how it can fixable for Indian system like before 00:01:05.250 --> 00:01:10.840 I go to the example and the case study to understand the applicability for the Indian 00:01:10.840 --> 00:01:17.360 condition briefly touch up on the points, which we discuss last day like firstly we 00:01:17.360 --> 00:01:23.950 discussed that for conversational technology, conversational construction methods, the construction 00:01:23.950 --> 00:01:31.060 is fully onsite and due to onsite activities for the construction sometimes due to the 00:01:31.060 --> 00:01:35.700 weather affect or the extreme weather affect the construction is not possible. 00:01:35.700 --> 00:01:41.140 For example during rainy season, during extreme winter, the construction is not possible. 00:01:41.140 --> 00:01:46.490 So as the result the construction become delayed and because of the delayed construction the 00:01:46.490 --> 00:01:51.740 time escalation and the cost escalation is obvious reason and the cost escalation is 00:01:51.740 --> 00:02:00.740 there then the affordability or the affordable housing within the cheaper cost will not possible. 00:02:00.740 --> 00:02:06.820 So how we can tackle this problem, now there are options, there are technologies, which 00:02:06.820 --> 00:02:12.610 actually involves the lot of manufacturing of the count building compounds of site that 00:02:12.610 --> 00:02:19.810 is in the factory or it is manufactured and in a suitable time it is transported from 00:02:19.810 --> 00:02:26.420 the factory and just assembled using either manual and the industrialized mode of assembling 00:02:26.420 --> 00:02:28.269 in the site. 00:02:28.269 --> 00:02:34.360 So site based activities are minimized so as result the time is minimized so these kind 00:02:34.360 --> 00:02:39.799 of technology, which involves lot of activities in the factories and less activity in the 00:02:39.799 --> 00:02:45.250 site it is called industrialized building system sometimes we call it as modular construction, 00:02:45.250 --> 00:02:53.120 sometime we call it as pre-fabricated construction, but this is viable option, which other countries 00:02:53.120 --> 00:02:54.290 are also tried. 00:02:54.290 --> 00:03:03.390 Next we discussed that two there are three type of industrialized building system, one 00:03:03.390 --> 00:03:10.330 is box system, which is nothing, but to contextualizes a building in terms of various cubes of the 00:03:10.330 --> 00:03:18.230 box as building units, second we discuss the panel system, panels are the low barring walls, 00:03:18.230 --> 00:03:21.819 which takes the load of the upper floors. 00:03:21.819 --> 00:03:27.469 So panels are very big load bearing and also there are compound based linear system, frame 00:03:27.469 --> 00:03:37.819 system, which is contextualizes the load bearing members like say column and also beams as 00:03:37.819 --> 00:03:43.739 individual compound and as a pre-fabricated compound and we have discussed last day that 00:03:43.739 --> 00:03:50.829 for Indian context apart from the box system and the panel system, the frame system is 00:03:50.829 --> 00:03:59.609 suitable because of the load condition because of the high availability of the manual labour, 00:03:59.609 --> 00:04:01.360 all this factors are involve. 00:04:01.360 --> 00:04:10.299 So compound based frame construction and also amount of in contextual bases, the panel construction 00:04:10.299 --> 00:04:16.370 also can be thought of if possible and then also we discuss that as process of the industrialization, 00:04:16.370 --> 00:04:21.989 it has specific stages India is currently in the stages just before the close system, 00:04:21.989 --> 00:04:29.460 so closed is nothing but where only selective few developers, develops the package the building 00:04:29.460 --> 00:04:31.160 as a package and delivers it. 00:04:31.160 --> 00:04:37.790 No other contractors or manufactures are allow to monitor or allow to alter the design or 00:04:37.790 --> 00:04:43.770 the constructions where the open system is a system where many contractors, many developers, 00:04:43.770 --> 00:04:47.750 many manufactures take part. 00:04:47.750 --> 00:04:51.030 It is more open to the various stay holders. 00:04:51.030 --> 00:04:57.650 So open system invites open economy, open and it discourages the monopoly, and close 00:04:57.650 --> 00:05:05.440 system basically ensure the quality because it is driven by only one unit, one suppliers 00:05:05.440 --> 00:05:08.430 but sometimes it encourages monopoly. 00:05:08.430 --> 00:05:15.319 So this two are the obvious close system is come first then it follows the open system. 00:05:15.319 --> 00:05:20.880 So Indian system right now there are various companies or various manufactures who are 00:05:20.880 --> 00:05:25.349 basically manufacturing building compound and government also is trying to co-op with 00:05:25.349 --> 00:05:28.330 the trained and the need for the day. 00:05:28.330 --> 00:05:35.370 So, with this background today we will see that how industrialized building system for 00:05:35.370 --> 00:05:41.730 India can be applicable for mass housing. 00:05:41.730 --> 00:05:47.919 So this picture we saw last day also that in typical modular construction schedule this 00:05:47.919 --> 00:05:54.870 is time saving because of the offsite construction activity, the site based construction activity 00:05:54.870 --> 00:05:59.190 is reduced and the site based construction activity actually done at the construction 00:05:59.190 --> 00:06:00.190 at the plan. 00:06:00.190 --> 00:06:06.479 So now we will see the case study how industrialized building system in India is available how 00:06:06.479 --> 00:06:12.250 much it can be applicable now before I show this example and the case study let me tell 00:06:12.250 --> 00:06:21.460 you that government labour rate like say CBIR or BMPTC or HUDCO lot of experiments where 00:06:21.460 --> 00:06:22.460 there. 00:06:22.460 --> 00:06:25.620 They have developed and Hindustan Private Limited they have developed very innovative 00:06:25.620 --> 00:06:31.690 building compounds and very building materials as such and those are tested also and those 00:06:31.690 --> 00:06:37.020 worked very nicely in some of the context, but here the examples we have taken it will 00:06:37.020 --> 00:06:42.590 show that how in a mass scale in a 1000 of unit can be developed generated using the 00:06:42.590 --> 00:06:49.759 building compounds in India context that will see in the next example. 00:06:49.759 --> 00:06:57.889 So the examples we have taken is the Maharashtra housing area and develop an authority and 00:06:57.889 --> 00:07:03.690 they have tired with another private company or the manufactures of the very innovative 00:07:03.690 --> 00:07:05.289 building materials. 00:07:05.289 --> 00:07:12.170 Which is called Shirke so the combination the partnership between the MHADA they take 00:07:12.170 --> 00:07:18.650 up all the most of the affordable housing and the housing for the poor in the whole 00:07:18.650 --> 00:07:25.860 state of the Maharashtra especially in the Mumbai major cities, so the materials they 00:07:25.860 --> 00:07:32.980 use for every component of the house like foundation floor slap, columns and beams, 00:07:32.980 --> 00:07:40.110 wall blocks, finishing and fixture, they take the floor slab to the wall blocks, they take 00:07:40.110 --> 00:07:41.990 the offsite mechanism system. 00:07:41.990 --> 00:07:48.920 They use the blocks like rain force concrete block or autoclaved aerated concrete block, 00:07:48.920 --> 00:07:52.360 similarly for this they take the light weight concrete or AC block. 00:07:52.360 --> 00:08:00.110 Whereas the foundation is done manually and RCC it is done onsite, similarly the finishing 00:08:00.110 --> 00:08:03.210 and fixtures these are done also onsite. 00:08:03.210 --> 00:08:08.190 So apart from this stages floor slabs, column and beam and the wall blocks the foundation 00:08:08.190 --> 00:08:14.180 and the finishing and fixtures are done on site and mostly they use mix on manual and 00:08:14.180 --> 00:08:19.479 they in foundation in column and beam and the wall blocks. 00:08:19.479 --> 00:08:25.729 Where the foundation and finishing and fixture say this three activities are taken place 00:08:25.729 --> 00:08:32.900 in the site, these are essentially buy and enlarge manual process. 00:08:32.900 --> 00:08:39.810 So to illustrate the example we have taken three different example, different cases, 00:08:39.810 --> 00:08:47.170 different projects at different locations like MHADA Shirke and Mazgaon in city of Mumbai 00:08:47.170 --> 00:08:54.730 and one project will be there for okay one project will be showing that under construction 00:08:54.730 --> 00:09:00.700 another project will be showing that it is completed last few years like 5 years and 00:09:00.700 --> 00:09:06.810 another project will be showing which is completed more than 20 years or before. 00:09:06.810 --> 00:09:11.690 So that we can understand its quality, its durability and its performances as building 00:09:11.690 --> 00:09:22.540 as the housing typology this is ongoing project on Mazgaon so basically it is redevelop of 00:09:22.540 --> 00:09:26.910 transit accommodations done by the Mankhurd . 00:09:26.910 --> 00:09:35.790 So it consist of 235 transit units in 5 numbers of G+7 and 66 number of EWS units with still 00:09:35.790 --> 00:09:38.930 17 sorted high. 00:09:38.930 --> 00:09:47.089 They have used a FSI of 2.67 and the densities above 3000 per hector those who are coming 00:09:47.089 --> 00:09:51.510 from planning or architecture background you can understand that this density is quite 00:09:51.510 --> 00:09:58.250 very high in terms of Indian context like in major cities you can see the net density, 00:09:58.250 --> 00:10:06.130 which is calculated in particular plot is like 1000 or 1500 maximum, but here they could 00:10:06.130 --> 00:10:09.490 achieve more than 3000. 00:10:09.490 --> 00:10:14.649 And they have constructed on frame system using preferred beam, column, slab and wall 00:10:14.649 --> 00:10:15.649 units. 00:10:15.649 --> 00:10:18.019 I will show how they have constructed. 00:10:18.019 --> 00:10:28.529 So you can see the columns, beams are joint here this is typical joint of a column you 00:10:28.529 --> 00:10:37.460 can see the shortage of column where a particular beam will be placed suitably and fixed suitably 00:10:37.460 --> 00:10:46.420 these are pictures showing column units have whole throughout the column length and it 00:10:46.420 --> 00:10:52.899 is inserted vertically like this so that this sockets are available for placing of these 00:10:52.899 --> 00:10:59.810 beams and these are some of the beam element you can see and over the beam you can see 00:10:59.810 --> 00:11:04.220 some of the hankering element where these slab element will be put and hankered. 00:11:04.220 --> 00:11:09.370 I will show the pictures so that you can understand well. 00:11:09.370 --> 00:11:16.899 So after placement of the columns and the beams like this, they place the slab element 00:11:16.899 --> 00:11:23.010 like this so all the slab elements are independent treated as the independent pre-fabricated 00:11:23.010 --> 00:11:28.880 element some are consisting of the RCC elements some are consisting of the cellular concretes 00:11:28.880 --> 00:11:36.339 block, which is aerated auto concrete element, which is completely manufactured in their 00:11:36.339 --> 00:11:43.030 own factory of Shirke and they transport all this materials and put in this manner. 00:11:43.030 --> 00:11:49.071 After placement of this slab component like this what they do they just fill up this slab 00:11:49.071 --> 00:11:54.340 over this concrete of three to four inch and they put the concrete in the wholes of the 00:11:54.340 --> 00:11:56.529 column. 00:11:56.529 --> 00:12:04.730 So whole column beam and the slab become fixed and it becomes more stable and all the individual 00:12:04.730 --> 00:12:11.320 compounds become one isolated strong compounds as whole. 00:12:11.320 --> 00:12:19.370 So after putting this screed concrete over the slab it becomes a complete strong floor 00:12:19.370 --> 00:12:28.010 as such and the whole process of placing column, beam, slaps and the screed concretes it takes 00:12:28.010 --> 00:12:33.570 not more than 8 to 10 days as I have learned from the flied visit, which we conducted in 00:12:33.570 --> 00:12:38.050 last one or two years in the various site of the Mahada housing projects. 00:12:38.050 --> 00:12:44.130 So the floor to floor cycle not more than 8 to 10 days, but at times it can take little 00:12:44.130 --> 00:12:52.930 more depending on whether, but technically it should not take 8 to 10 days. 00:12:52.930 --> 00:12:57.889 So here you can see that how manual labour is used to. 00:12:57.889 --> 00:13:04.210 Find tuning of the slab component and hankering the slab component with the hankers and the 00:13:04.210 --> 00:13:10.680 Shirke left over the main component after this fine tuning of the slap component then 00:13:10.680 --> 00:13:14.430 the screed concrete will be put and it will be used. 00:13:14.430 --> 00:13:20.480 You can see the typical pictures of the slap component, every slab component have the grooves 00:13:20.480 --> 00:13:27.050 like that so that after placement of the slab component it can be acted like silage one 00:13:27.050 --> 00:13:32.140 unified component as slab and so that it also bind well. 00:13:32.140 --> 00:13:36.250 It is locked well with each other like this. 00:13:36.250 --> 00:13:41.160 This is the picture of the whole floor. 00:13:41.160 --> 00:13:47.540 It typical floor, this is how their lifting any pre-fabricated component using quinces 00:13:47.540 --> 00:13:55.149 and this is the typical picture of a wall component where their using the AC block, 00:13:55.149 --> 00:14:01.769 which we call as light weight block as the wall component also they use the binder concrete 00:14:01.769 --> 00:14:09.171 binder to so that it becomes strong, it become unified and this blocks are very light weight. 00:14:09.171 --> 00:14:14.610 This blocks are very light weight single person can carry and it is also very soft so that 00:14:14.610 --> 00:14:21.430 some person can make groove or can break it and use it like a common brick, but it is 00:14:21.430 --> 00:14:27.630 manufactured in such dimension which is standardized dimension and practically u do not need to 00:14:27.630 --> 00:14:39.410 cut AC block too many times so that you reduce the time requirement for the project construction. 00:14:39.410 --> 00:14:43.920 Now in this picture you can see the some of the AC blocks tacit in the site. 00:14:43.920 --> 00:14:50.760 these are the window block, this blocks are also pre-fabricated, it is sometime pre-fabricated 00:14:50.760 --> 00:14:55.850 at the factory, sometimes pre-fabricated at the site and place like that and these are 00:14:55.850 --> 00:15:05.800 the AC block was how it looks from the outside and you can see the slab component, photography 00:15:05.800 --> 00:15:13.950 is taken at the floor level so that you can understand how the joinery and the arrangement 00:15:13.950 --> 00:15:19.570 for ceiling fan is kept here. 00:15:19.570 --> 00:15:28.500 So they use the slab blocks and wall panel in this size, you can see that these 600 millimetre 00:15:28.500 --> 00:15:37.209 almost 600 millimetre is the standard modern size what they use and for the blocks they 00:15:37.209 --> 00:15:48.670 use 4 inch, 3 inch or 6 inch module and the length can be one to four meter for this slabs, 00:15:48.670 --> 00:15:54.250 Len can be 650 for the blocks for the wall blocks and for wall panels it is one to three 00:15:54.250 --> 00:16:04.209 meters so keeping the thickness as 3 to 5 inch and width as 2 feet they can for the 00:16:04.209 --> 00:16:09.470 one to two meters and 3 meter. 00:16:09.470 --> 00:16:16.709 Now lets us talk about its strength and durability, the whole structure is designed in such way 00:16:16.709 --> 00:16:26.550 that it will give a life cycle of at least 50 years against its durability, its strength 00:16:26.550 --> 00:16:34.220 against all the possible load component in the building and they have waited the design 00:16:34.220 --> 00:16:42.560 with help of IIT Bombay and this is the clause some of the clauses in the contractor between 00:16:42.560 --> 00:16:47.670 the developer or the manufacture and the government housing authority, housing board authority 00:16:47.670 --> 00:16:53.910 where you can see that 50 years they have given guarantee against the durability and 00:16:53.910 --> 00:16:57.550 strength for 50 years at least so 50 years. 00:16:57.550 --> 00:17:02.230 So that is there and it is still working for more than 20 years, some of the projects, 00:17:02.230 --> 00:17:04.110 this particular project was under construction. 00:17:04.110 --> 00:17:10.690 Now this are the arrangement how they put the convicts for the electrical pipelines 00:17:10.690 --> 00:17:15.880 usually in the normal RCC construction, with we place electrical concretes floor in this 00:17:15.880 --> 00:17:19.940 slabs, I mean roof slab during the costing, 00:17:19.940 --> 00:17:27.580 But here what they do during the secrete concreting, which I discussed little before over the pre-fabricated 00:17:27.580 --> 00:17:32.710 slab component on the screed concrete they take the conflict like that and from the screed 00:17:32.710 --> 00:17:41.390 concrete they take up to the switch board level, but in the conventional construction 00:17:41.390 --> 00:17:43.350 it is taken from the ceiling. 00:17:43.350 --> 00:17:48.920 So that is difference and another point is you can see that it is very easily cut by 00:17:48.920 --> 00:17:55.410 common even semi-scale labour so that they can put this place for concrete like this 00:17:55.410 --> 00:17:56.410 also. 00:17:56.410 --> 00:18:02.720 This is exposed conflicts these are some of the pictures showing how the plumbing arrangements 00:18:02.720 --> 00:18:06.060 are done. 00:18:06.060 --> 00:18:16.660 The outlets and some of the drops slabs, which is done incite to those could be kind of a 00:18:16.660 --> 00:18:24.320 next stage of improvement, but these are the areas where it is working very nicely as a 00:18:24.320 --> 00:18:28.630 product as design, these are the pictures which is under construction. 00:18:28.630 --> 00:18:33.790 Now we will see some of the project, which is already constructed to apprise or to assess 00:18:33.790 --> 00:18:38.930 their efficacy against the performances. 00:18:38.930 --> 00:18:45.230 Now this project the new Hindu Mills project is in Mazgaon, now in Mumbai you now that 00:18:45.230 --> 00:18:49.280 there are many mills, and land so the authority or the government of Maharashtra they took 00:18:49.280 --> 00:18:54.330 a policy to use that Mill lands for the affordable housing projects. 00:18:54.330 --> 00:19:01.070 So this is one of the biggest Mill land housing called New Hindu Mills basically it is combination 00:19:01.070 --> 00:19:06.301 of few Mill land and housing where Mill land where they have placed also the original staff 00:19:06.301 --> 00:19:12.440 of the Mills some transit accommodation and few EWS and LIG population. 00:19:12.440 --> 00:19:19.700 You can see the adjoining area is full of kind slum like situation and this is the housing 00:19:19.700 --> 00:19:22.160 project which we are discussing. 00:19:22.160 --> 00:19:29.050 So far 18 housing projects in the Mill land was already executed more than 10000 units 00:19:29.050 --> 00:19:33.860 till 2014 when we took the study that time was done. 00:19:33.860 --> 00:19:39.540 So new Hindu Mill project is the largest and having more than 5000 units, it is one of 00:19:39.540 --> 00:19:40.940 the biggest projects. 00:19:40.940 --> 00:19:45.480 So objective of this Mill land housing is to utilize the abundant mill, land in the 00:19:45.480 --> 00:19:51.660 core area of the city in partnership with the land owner and sharing of the housing 00:19:51.660 --> 00:19:59.200 unit for Mill land employers and the MHADA for transit as well as EWS unit that I told. 00:19:59.200 --> 00:20:04.200 For development of the other projects, other slums some of the transit house will be required 00:20:04.200 --> 00:20:11.970 so those transit houses will be accommodate in this project that was one of the objective. 00:20:11.970 --> 00:20:20.010 So you can see the land area was more than 3 hector, 3.7 hector and it was full G+22/23/24 00:20:20.010 --> 00:20:27.220 storied block having 8 to 12 tenements per floor and you can see the density. 00:20:27.220 --> 00:20:34.470 It is very, very high density and dense project with the compact development, which is very 00:20:34.470 --> 00:20:41.280 high, but with this density at least the housing units are affordable for the poor and the 00:20:41.280 --> 00:20:46.220 lower middle income group or the lower income group for economical weaker session at this 00:20:46.220 --> 00:20:49.120 density otherwise it is not affordable. 00:20:49.120 --> 00:20:55.910 You can see the layout plan, the layout plan each building blocks are joint together in 00:20:55.910 --> 00:21:03.480 such way so that it makes internal cote here for enough light ventilation and you can see 00:21:03.480 --> 00:21:11.000 the typical building units is repetitive because we talked last day also that the whole industrialized 00:21:11.000 --> 00:21:17.260 process or pre-fabricated process runs on the standardized design, standardized module, 00:21:17.260 --> 00:21:23.270 so each housing unit is consisting of standardized module so we will see one such module in detail 00:21:23.270 --> 00:21:24.750 in the next day. 00:21:24.750 --> 00:21:31.560 So this is standardized module of a typical building block it consist 12 unit this is 00:21:31.560 --> 00:21:38.420 the one unit consisting one multipurpose room or living room, one bedroom, one WUC, and 00:21:38.420 --> 00:21:45.640 one bus area and one kitchenette with some storage area and this is the common core with 00:21:45.640 --> 00:21:52.070 staircase and live block where this are the common lobby to provide the access to each 00:21:52.070 --> 00:21:53.290 and every unit. 00:21:53.290 --> 00:22:02.910 So this is the standardized module, which they use out of this module this component 00:22:02.910 --> 00:22:12.830 like this lift core and the staircase core this is done in using the RCC basically and 00:22:12.830 --> 00:22:16.430 some of the element like bigger columns these are also RCC. 00:22:16.430 --> 00:22:24.540 But apart from that most of the elements are done by the pre-fabricated wall blocks and 00:22:24.540 --> 00:22:28.160 pre-fabricated components. 00:22:28.160 --> 00:22:36.250 This is finished picture of floor where you can see the placement of the lobby component 00:22:36.250 --> 00:22:46.660 from bottom it is painted in colours and this is the picture of the typical kitchen where 00:22:46.660 --> 00:22:54.110 you can see the kitchen slab and the slab component only one thing that since this particular 00:22:54.110 --> 00:23:03.560 design does not have any balcony as such, so their using the windows for today the storage 00:23:03.560 --> 00:23:09.350 purpose or in few cases we have also found that in lobby areas they have used the lobbies 00:23:09.350 --> 00:23:18.720 for keep their today think and this is the picture taken from inside where you can see 00:23:18.720 --> 00:23:25.580 that the internal arrangement of the slabs and how they taken the electrical pipe lines, 00:23:25.580 --> 00:23:27.410 which is basically exposed. 00:23:27.410 --> 00:23:31.060 So these are the variation and outcome of the project. 00:23:31.060 --> 00:23:37.630 This is typical unit plan, having one living room, one bedroom, kitchen and the WBC and 00:23:37.630 --> 00:23:40.800 one bath now only one path. 00:23:40.800 --> 00:23:46.600 This is very compact design, very compact design within this much of 225 sq feet of 00:23:46.600 --> 00:23:48.150 corporate area. 00:23:48.150 --> 00:23:54.110 So only think that it could be accommodated another very small balconies so that people 00:23:54.110 --> 00:24:00.310 could use it in multipurpose way other than that it is very nice design to accommodate 00:24:00.310 --> 00:24:05.740 and to generate affordable house within this price and within this much of time. 00:24:05.740 --> 00:24:10.670 So this is general views of the project you can see it is huge project. 00:24:10.670 --> 00:24:18.390 This is the view from inside of the project. 00:24:18.390 --> 00:24:22.560 Some other views. 00:24:22.560 --> 00:24:29.740 Now we come to one project which is completed long back more than 20 years to see its quality 00:24:29.740 --> 00:24:35.800 it is projection and other housing project, you can see the project like this, some of 00:24:35.800 --> 00:24:44.370 surface tax is missing during the investigation, during our visit, but those are tax developed 00:24:44.370 --> 00:24:49.980 due to poor maintained physically, it is not structural track as such because structure 00:24:49.980 --> 00:24:57.560 is durable enough giving 50 years of the durability and the strength as per the design. 00:24:57.560 --> 00:25:04.010 So because of the low maintenances, poor maintenances of the projects it is showing little bit of 00:25:04.010 --> 00:25:08.640 cracks and some different colours, but otherwise the structure is good enough. 00:25:08.640 --> 00:25:13.880 So overall influences from our this particular set of projects is that super structure has 00:25:13.880 --> 00:25:21.340 been found say structurally against whether effects and all kind of load features like 00:25:21.340 --> 00:25:28.220 say live loaded, loads and load everything, the pre-fabricated elements like wall slab 00:25:28.220 --> 00:25:29.220 blocks. 00:25:29.220 --> 00:25:34.380 Have perfects used right kind of materials consisting weight, cost, energy, however it 00:25:34.380 --> 00:25:38.960 needs to be customized unit for the accommodating electrical and plumbing pipe that when we 00:25:38.960 --> 00:25:44.000 discussed in the fight we understood that some of the units could be integrated to have 00:25:44.000 --> 00:25:47.930 to the plumbing and electrical installation so that during the construction somebody does 00:25:47.930 --> 00:25:50.690 not have to make grooves separately. 00:25:50.690 --> 00:25:57.290 Joinery and fittings are the areas where further improvement can be done, but as if now the 00:25:57.290 --> 00:26:02.430 projects are functioning absolutely in the good condition it is very viable and visible 00:26:02.430 --> 00:26:08.150 option using frame construction in Indian context what we discussed. 00:26:08.150 --> 00:26:15.700 Now let us see a comparative cost of the two projects to compare we have taken two other 00:26:15.700 --> 00:26:22.600 projects so that we can have comparison, we took we took which is basically being developed 00:26:22.600 --> 00:26:29.460 by in Kolkata is lower income group housing and we have taken sukaho housing which is 00:26:29.460 --> 00:26:34.730 develop by TATA housing and also we have taken new Hindu Mills housing, we have taken the 00:26:34.730 --> 00:26:37.870 cost compound from their website. 00:26:37.870 --> 00:26:44.420 So you can see the cost compound it is much lower than the other conventionally constructed 00:26:44.420 --> 00:26:55.980 projects almost 30 to 40% cost saving as their and if you see the time in this project sukaho 00:26:55.980 --> 00:27:00.540 and we should go they are taking more than 4 years, but in this case the new Hindu Mills 00:27:00.540 --> 00:27:06.030 housing they have taken two to three years because this project is very large project 00:27:06.030 --> 00:27:11.670 otherwise in other projects they have taken one and half years or two years or even less 00:27:11.670 --> 00:27:12.670 than that. 00:27:12.670 --> 00:27:18.791 So median duration of the project is one and a half year for a mid 500 units or so, but 00:27:18.791 --> 00:27:24.070 here the project was so big that 5000 units it took two to three years still it is less 00:27:24.070 --> 00:27:29.080 than other conversational projects. 00:27:29.080 --> 00:27:31.430 So now we come to the present status of India. 00:27:31.430 --> 00:27:41.280 In India now we have the pradhan mantri mudra yojana by the government of India next we 00:27:41.280 --> 00:27:45.020 will discuss the pradhan mantri mudra yojana in detail and under the pradhan mantri mudra 00:27:45.020 --> 00:27:47.920 yojana want technology submission is contextualized. 00:27:47.920 --> 00:27:54.910 In this technology submission they have identified total 16 technologies NITS their actually 00:27:54.910 --> 00:28:06.630 basically delivering are offering the research for the technology submission because not 00:28:06.630 --> 00:28:11.470 all the technology whatever the identified are tested in the field except one or two 00:28:11.470 --> 00:28:17.310 which I showed today that is why it is under experimentations so let us summarized the 00:28:17.310 --> 00:28:24.470 discussion what we had today before I conclude so today we discussed the some of the example 00:28:24.470 --> 00:28:28.370 of industrialized building system in Indian condition. 00:28:28.370 --> 00:28:33.320 We told that in India after the independences there are lot of experimentation in material 00:28:33.320 --> 00:28:40.400 and the systems of the buildings by the government organization NGO, but those who have are basically 00:28:40.400 --> 00:28:45.550 focused on a particular building component or material, but today we showed another examples 00:28:45.550 --> 00:28:52.000 where a particular agency government agency is delivering with the partnership with another 00:28:52.000 --> 00:28:59.750 private developer a complete project using total pre-fabricated units using pre-fabricated 00:28:59.750 --> 00:29:04.680 columns, beams, slab component and wall block component. 00:29:04.680 --> 00:29:11.720 So that the project is being completed within the two years for mid sage mass housing project, 00:29:11.720 --> 00:29:17.360 which is comparable to other projects conventionally constructed, other projects are taking four 00:29:17.360 --> 00:29:24.330 to five years, but here they are taking two years median and also the project cost is 00:29:24.330 --> 00:29:31.210 also less than other project so the learning point in this discussion is that for India 00:29:31.210 --> 00:29:37.650 the mass housing project using pre-fabricated building components or pre-fabricated building 00:29:37.650 --> 00:29:44.550 technology or industrialized building system is fusible and probably this is future and 00:29:44.550 --> 00:29:49.020 considering this essence government of India they have contextualized the technology submission 00:29:49.020 --> 00:29:55.940 under Pradhan Mantri Mudra Yojana which we discussed tomorrow or next lecture in greater 00:29:55.940 --> 00:29:56.740 details so thank you.
