in order to determine the length of soldier piles. So, I
have calculated by using LRFD methods again that selected the soldier pile
(W12 × 26) that should be 13 ft long, and the perpendicular support (w8 × 12)
should be 6 ft long as the support maglev construction.
Cost of Maglev Infrastructure
The proposed maglev infrastructure, therefore, requires shoring, excavation, structural steel, and concrete operation and thus I have calculated the estimate considering the following components:
Shoring at 13′ deep with w24 × 26 steel soldier piles at 6′ OC both sides $2/lf; top
rail w8 × 12 both sides $2/lf; 6′ length w8 × 12 perpendicular support 20 OC
$2.lf; protection board 1,372,800 ft

both sides at $4/ft

; and thus the total cost
would be $23,724,800.

cost for digging, stock piling, and backfilling and the total cost would be

Cost of materials: 100 Miles maglev system with structural steel (w24 × 84) support
for 8 lanes is $354,816,000; 2 × 2 structural concrete strip footing at $150/yd

is $16,896,000; and thus the total cost of material is $528,156,445.
Cost of labor: 200 Iron workers for 2704 working days at $100/h; 100 concrete
cement workers for 2704 working days at $90/h; 100 laborers for 2704 working
days at $70/h; 50 equipment operators for 2704 working days at $100/h; and thus
the total labor cost is $886,912,000 considering standard 8 h a day.
Equipment cost: Ten small renting at $1000/day; 10 small tool renting at $250/day;
271 concrete pumps at $2000/each; and thus the total equipment cost is
$34,342,000.
Other cost: Engineering service at $5/ft

; survey team at $4400/day for each working day; and thus the total cost is $349,817,600. The net construction cost by
adding 10% general condition, 10% overhead and profit, and 3% contingency
into the excavation, material, labor, equipment, and other cost would be
$3,587,063,487.
Cost of Traditional Road Infrastructure
A typical highway consists of 8″ asphalt surface course, 4″ binder course, 4″ base
course, and 12″ aggregate with standard wire mesh or framing and thus we have
calculated the estimate considering the following components:
