Looking to the list of materials in Exercise 4, and assuming that each steel member was the same length, let’s say approximately 30′, and all things being equal (which they never are, but…), which element would take the most labor to install?

Data from Exercise 4

Including allowances for gussets, etc., compute the total tonnage for the following quantities and sizes of rolled steel members. You will have to look up the weights of the steel members for this exercise.

a. 100 LF of 3.5 × 3.5 × 1/4 angle

b. 250 LF of 12 × 3 × 5/16 channel

c. 85 LF of W36 × 135

d. 525 LF of 4 × 4 × 1/4 HSS
