Installed project cost calculator

Sum materials, engineering, labor and contingencies on the same project scope.

Units

I = L_{d} \times c_{d} + N_{d} \times c_{\text{damper}} + N_{\text{worker}} \times h_{\text{labor}} \times w + C_{\text{other}}

Calculator

Enter the values you know and leave one box empty. Calculate finds the empty one, the result or any input.

Given

I = 210 \times 38 + 5 \times 280 + 3 \times 24 \times 42 + 1800 = 14{,}204
