1. Financial Feasibility
1.1 Cost Estimation for wheel chair + blind people(alternative 1)
Costs of the project can be divided in to several parts. They are land acquisition cost, ground improvement cost, excavation cost, construction cost, parking area costs, landscaping cost (include road network) and costs in operational stages.
Land acquisition costs
Conversion Factor, 1 perch = 272.25sqft
Cost per perch = Rs.250000to Rs.550000
= Rs.400000 (Average)
Cost per sqft = Rs.1469
Total land area = 174240 sqft
Total cost for the land = 174240∗1469
= Rs.255 million
Ground improvement
As the ground improvement method shallow foundations are used in the project. Based on the borehole results which is obtained from the nearest site. Shallow foundation is suitable for a two stored building
Total no of a pad footings = 133
Average total volume =133* {(0.5*0.5*3.25) + (2.5*2.5*0.75)}
=732m3
Grade of concrete = C25
Cost of C30 grade concrete = Rs. 14,291 /m3
Concrete cost for pad footings =732∗14291
= Rs.10.5 million

Total cost = Rs. 2 million/ year
Total cost for 3 years = Rs. 6 million
Total construction cost is the sum of all the above mentioned construction costs
Total construction cost = Rs. 495.85million
Costs during the operational period
Electricity
