PART- I EXTERNAL DEVELOPMENT WORKS

A.Civil Works 1.Existing ground levels at the time of commencement of villa construction works were not same for the villas. There was a variation from 400 to 750 mm down from existing road level. Accordingly, the depth of foundation & earth filling varied in the villas 2.The constructed area on ground floor varies from minimum 16% to maximum 65% of the plot area. Hence, excavated earth available from foundation / provision basement varies from plot to plot. Also, spread of this earth over the un-built area leads to the variation in cost. 3.The position of the plot varies from one side open to 3 sides open. Which lead to the variation in the cost of boundary wall, & steel railing etc 4.In some plots where the basements are constructed, the area of basement varies from 10% to 50% of the plot area, resulting the variation in cost of earth filling. 5.Cost varies due to construction of spiral staircase (approach to garage/ servant roof) wherever it is constructed.

EXTERNAL DEVELOPMENT WORKS B.Plumbing Works. 1.Due to variation in positioning of working toilet / kitchen and other toilets, length of sewer line varies affecting the cost of S.W. pipe, excavation & PCC all around the S.W pipe.. 2.Number of man holes also varies from plot to plot due to the change in length of sewer line as explain in SL. 1, para B above.

EXTERNAL DEVELOPMENT WORKS C.Electrical Works. 1.Variation in location of earth pits, length of GI/Copper strip from earth pits to meter board varies.. 2.Copper conductor wire and PVC conduits from meter board to DB varies due to the change in its position. Where as the number of DB also varies depending upon the construction of basement & first floor.

PART- II MAIN VILLA WORKS

A. Civil Works. 1.By way of permutation and combination there is 150 combinations and as such no single villa is similar to another.. 2.Though, design selection and the area to be constructed from the selective design were given by the individual owner. But, during the construction of the villas several members made changes in their villas, already approved / given for the construction. 3.Due to provision of basement cost of villa varies due to additional foundation works, construction of RCC wall, water proofing, 115 mm thick brick wall, high plinth level and the provision kept for the extension of roof slab at GF level. Also, due to change in length of provision basement wall, cost of villa varies.. 4.Plinth level varies from 600mm to 1200mm level i.e. the level above the road. This is due to provision basement / basement & due to the specific instruction by the individual owner to have the plinth height higher than the normal plinth height i.e. 600mm provided in general villas. Hence, resulting in extra cost of foundation work & filling of earth with in the built-up area etc.

MAIN VILLA WORKS A.Civil Works. 5.In some of the villas clear height is more than the normal height i.e. 3.20m in general, hence the variation in the cost.. 6.Wherever the double story or triple story has constructed in the villas, (i.e. garage with servant quarter or the first floor on main villas) the cost of terrace work along with parapet wall etc and the cost of foundation is divided & hence the per sft cost is lower than single story. 7.Due to selection of wood works from teak and marandi as per individual choice, cost variation takes place.

MAIN VILLA WORKS B.Plumbing Works. 1.Due to variation in location of PVC water tank at terrace, the length of GI pipe connecting the water tank varies.

MAIN VILLA WORKS C.Electrical Works. 1.Due to variation in design and number of electrical points cost varies from plot to plot. Also cost varies due to full and half electrical works, selected by the individual members.

PART- III COST IMPLICATIONS

S. N. Factors affecting the variation in the cost Cost implication Remarks A External Development Works 1 Existing ground levels at the time of commencement of villa construction works by JRC were not same for all villas. There was a variation from 400 to 750 mm down from existing road level. Accordingly, the depth of foundation & the earth filling vary in the villas. Cost varies from Rs. 7/- to 148/- per sqm Cost of villas 7, 29, 33, 43, 87 & 118 are Rs. 3544, , , 92333, & respectively 2 The constructed area on ground floor varies from minimum 16% to maximum 65% of the plot area. Hence, excavated earth available from foundation / provision basement varies from plot to plot. Also, spread of this earth on un- built area leads to the variation in cost. Rs. 70/- per sqm (refer item no i.e. providing manure into the earth up to 60 cm depth) Cost of villas 7, 29, 33, 43, 87 & 118 are & respectively COST IMPLICATIONS

S. N. Factors affecting the variation in the cost Cost implication Remarks 3 The position of the plot varies from one side open to 3 sides open. Which lead to the variation in the cost of boundary wall, & steel railing etc a Extra railing of boundary wall due to road facing of corner plots. Extra Rs. 960/- per RM Villa 39 has 52.53m while Villa m hence, costs are Rs & respectively. b Extra cost due non shared wall i.e. Independent Vs common wall of corner plots. Extra Rs. 645/- per RM Villa 33 & 29 both has independent walls of 2 sides hence, extra cost of Rs for both. c Extra cost due to more height of boundary wall towards park facing Extra Rs. 375/- per RM Villa 33 & 29 both has one wall at park facing. Hence, extra cost of Rs for both. 4 Cost varies due to construction of spiral staircase (approach to garage/ servant roof) wherever it is constructed Extra cost of Rs /- for one flight only. Villa 33 has one flight. However the same vary as per no. of flights. COST IMPLICATIONS

S. N. Factors affecting the variation in the cost Cost implication Remarks 5 Due to variation in positioning of working toilet / kitchen and other toilets, length of sewer line varies affecting the cost of S.W. pipe, excavation & PCC all around the S.W pipe Cost Rs 653/- per Rm Cost of villas 29, 33, 42, 43 & 87 are & respectively. 6 Number of man holes also varies from plot to plot due to the change in length of sewer line as explain above Cost of Rs. 4500/- per manhole Cost of villas 33, 42, 39 & 87 are 39600, 22000, & respectively. 7 Copper conductor wire and PVC conduits from meter board to DB varies due to the change in its position. Where as the number of DB also varies depending upon the construction of basement & first floor Rs. 455/- per Rm Villa 29, 33 & 87 are 20, 35 & 16 Rm respectively. 8 Also, variation in location of earth pits, length of GI/Copper strip from earth pits to meter board varies Cost Rs 78/- per Rm COST IMPLICATIONS

S. N. Factors affecting the variation in the cost Cost implication Remarks BMain Villa 1 Due to provision of basement cost of villa varies due to additional foundation works, construction of RCC wall, water proofing, 115 mm thick brick wall, high plinth level and the provision kept for the extension of roof slab at GF level. Also, due to change in length of provision basement wall, cost of villa varies. Extra cost varies from Rs. 50/- to Rs. 65/- per sft. 2 Plinth level varies from 600 mm to 1200mm level i.e. the level above the road. This is due to provision basement / basement & due to the specific instruction by the individual owner to have the plinth height higher than the normal plinth height i.e. 600mm provided in general villas. Hence, resulting in extra cost of foundation work & filling of earth with in the built up area etc. Extra cost varies from Rs. 40 to Rs. 50/- per sft for extra height of plinth i.e mm in place of 600 mm Plinth level of villas those have provision basement is 1200mm in place of 600mm like villa 33 & 29 3 In some of the villas clear height is more than the normal height i.e. 3.20m in general, hence, the variation in the cost. Extra cost varies from Rs. Rs. 4/-to Rs. 5/- per sft for every 10cm addl. height COST IMPLICATIONS

S. N. Factors affecting the variation in the cost Cost implication Remarks 4 Wherever the double story or triple story has constructed in the villas, (i.e. garage with servant quarter or the first floor on main villas) the cost of terrace work along with parapet wall etc. and the cost of foundation is divided & hence the per sft cost is lower than single story Extra cost varies about Rs. 50/- per sft Villa no. 2 & 87 both are normal plots but cost of foundation & terrace comes to Rs. 245/- and Rs. 193/- per sft respectively. 5 Due to selection of wood works from teak and marandi as per individual choice, cost variation takes place Extra Cost varies from Rs. 55/- to Rs. 70/- per sft for using teak wood in place of marandi Many villas have the same like villa no. 29 & Villa no. 33 etc. 6 Due to sloping design of sunshades instead of normal design Cost of normal & sloping sunshades are Rs. 85/- & Rs. 335/- per sft respectively All villas have sloping sun shades in place of normal. 7 Due to variation in design and number of electrical points cost varies from plot to plot. Also, cost varies due to full and half electrical works, selected by the individual members. COST IMPLICATIONS
