Which of the following is not a basic method for estimating metal studs and track?

A. Take off the stud and track separately by the LF. Price studs and track totals separately for materials and labor costs.

B. Calculate the SF area of the wall and convert material and labor costs to SF.

C. Calculate the SF area as in the method above and estimate the cost of panel fabrication and the cost of erection separately. Include equipment costs required for erection.

D. Take off the wall by the LF, where 1 LF of wall is equal to 1 LF of length by height. Convert material and labor costs to LF of wall based on a standard height.
