Calculations and Estimates
1. Foundation
 * Total length of walls: 113 + 113 + 30 + 30 + 45 + 45 = 376 feet
 * Foundation width: Assuming 1 foot
 * Foundation volume: 376 * 1 * 1 = 376 cubic feet
 * Cement: 376 cubic feet * 1.5 bags/cubic foot = 564 bags
 * Cement cost: 564 bags * 540 BDT/bag = 304,440 BDT
 * Steel: Assuming 50 kg/cubic foot
 * Steel weight: 376 cubic feet * 50 kg/cubic foot = 18,800 kg
 * Steel cost: 18,800 kg * 97000 BDT/ton = 1,822,600 BDT
 * Sand: 376 cubic feet
 * Sand cost: 376 cubic feet * 35 BDT/cubic foot = 13,160 BDT
 * Labor: Assuming 10 days for foundation work
 * Labor cost: 10 days * 800 BDT/day = 8000 BDT
 * Total foundation cost: 304,440 BDT + 1,822,600 BDT + 13,160 BDT + 8000 BDT = 2,148,200 BDT
2. Superstructure
 * Wall area: 1620 square feet * 2 (for both sides) = 3240 square feet
 * Wall volume (assuming 5 inches thickness): 3240 square feet * 5/12 feet = 1350 cubic feet
 * Cement: 1350 cubic feet * 1.5 bags/cubic foot = 2025 bags
 * Cement cost: 2025 bags * 540 BDT/bag = 1,093,500 BDT
 * Steel: Assuming 50 kg/cubic foot
 * Steel weight: 1350 cubic feet * 50 kg/cubic foot = 67,500 kg
 * Steel cost: 67,500 kg * 97000 BDT/ton = 6,557,500 BDT
 * Sand: 1350 cubic feet
 * Sand cost: 1350 cubic feet * 35 BDT/cubic foot = 47,250 BDT
 * Bricks: Assuming 60 bricks/square foot
 * Brick quantity: 3240 square feet * 60 bricks/square foot = 194,400 bricks
 * Brick cost: (Assuming 100 bricks/bag) 194,400 bricks / 100 bricks/bag * 500 BDT/bag = 972,000 BDT
 * Labor: Assuming 30 days for superstructure
 * Labor cost: 30 days * 800 BDT/day = 24,000 BDT
 * Total superstructure cost: 1,093,500 BDT + 6,557,500 BDT + 47,250 BDT + 972,000 BDT + 24,000 BDT = 8,794,250 BDT
3. Finishing
 * Plaster: 3240 square feet
 * Plaster cost: 3240 square feet * 20 BDT/square foot = 64,800 BDT
 * Paint: 3240 square feet * 3 coats * 15 BDT/square foot/coat = 145,800 BDT
 * Tiles: 1620 square feet
 * Tile cost: 1620 square feet * 65 BDT/square foot = 105,300 BDT
 * Plumbing package: 50,000 BDT
 * Electrical package: 100,000 BDT
 * Doors (assuming 8 doors): 8 doors * 13000 BDT/door = 104,000 BDT
 * Windows (assuming 12 windows): 12 windows * 10000 BDT/window = 120,000 BDT
 * Labor: Assuming 20 days for finishing
 * Labor cost: 20 days * 800 BDT/day = 16,000 BDT
 * Total finishing cost: 64,800 BDT + 145,800 BDT + 105,300 BDT + 50,000 BDT + 100,000 BDT + 104,000 BDT + 120,000 BDT + 16,000 BDT = 706,100 BDT
4. Mobilization Cost
 * Mobilization cost: 100,000 BDT
