To calculate the cost for replacing the linear feet of truss, which formula is used?

In calculating the cost for replacing the linear feet of truss, the focus is on determining how much material is needed based specifically on the width of the roof that the trusses will support. The correct calculation involves multiplying the total number of trusses by the width of the roof without overhangs.

This approach allows you to assess the total linear footage required for the trusses across the span of the roof. If you think of each truss needing a certain length of material corresponding to its span, multiplying the number of trusses by the effective width gives you the total linear feet necessary.

This formulation is practical for estimating material needs accurately for construction and renovation, ensuring you account for each truss's contribution to the overall structure of the roof. It effectively translates the physical dimensions of the roof area into the quantity of ties needed, making it essential for budgeting and procurement decisions in construction projects.
