Measuring site work, Excavation and Piling

Bid drawings typically include very little material about the precise requirements of site work operations, measuring site work and excavation work differs from measuring most other works on a construction project. The actual site work conditions are not provided and also the dimensions of the excavations are not known during the pre-construction phase. The precise measurement of the excavation and backfill of the earth material and topsoil is important for a contractor to decide upon the total cost required for the process. All the works should be carried out under OSHA (Occupational Safety and Health Administration) standards to ensure the safety of the workers.

(b) shows the cross-sectional dimensions for the structural steel section known as
C10 x 20 (channel with a nominal depth of 10 in., weighing 20 lb/ft). The
American Institute of Steel Construction Structural Steel Handbook lists the
following properties for the cross section: A=5.88 in?, Ix =78.9 in4, and ly =2.81 in*. If
a W8 x 67 section is joined to a C10 x 20 section to form a structural member that
has the cross section shown in Figure (c),

I'm quite confused whether we're going to consider the friction at C going to the left or going to the right since by inspection, the object has the tendency to slip to the right so we'll have friction on the opposite direction. On the other hand, we can have friction to the right since there is force P acting on member BC. How do you solve this?
