Type of Cost Item Cost Calculation Cost
Material Cost (M) Carbon Steel Solid Bar ( kg) x ($4.30 per kg) x (2 Trusses) = $141,965.62
Carbon Steel Hollow Tube ( kg) x ($6.30 per kg) x (2 Trusses) = $18,303.84
Connection Cost (C) (22 Joints) x (400.0 per joint) x (2 Trusses) = $17,600.00
Product Cost (P) x60 mm Carbon Steel Bar (%s per Product) = $1,000.00
2 - 65x65 mm Carbon Steel Bar (%s per Product) = $1,000.00

x150 mm Carbon Steel Bar (%s per Product) = $1,000.00
x160x8 mm Carbon Steel Tube (%s per Product) = $1,000.00
Site Cost (S) Deck Cost (10 4-meter panels) x ($4, per panel) = $47,000.00
Excavation Cost (19,400 cubic meters) x ($1.00 per cubic meter) = $19,400.00
Abutment Cost (2 standard abutments) x ($5, per abutment) = $11,000.00
Pier Cost No pier = $0.00
Cable Anchorage Cost No anchorages = $0.00
Total Cost M + C + P + S $160, $17, $14, $77, = $269,269.46
