212 CHAPTER SIXTEEN
The specifications should list the type of coating, num-
ber of coats, and finish required on the various surfaces
throughout the project. Interiors receive different treatment
than exteriors; different material surfaces require different
applications and coatings—all of this should be in the speci-
fications. Paints may be applied by brush, roller, or spray gun.
The method to be used is also included in the specifications.
Sometimes, the specifications call for prefinished and
factory-finished materials to be job finished also. Except for
possible touch-ups, this is usually due to an oversight in the
architect/engineer’s office and the estimator should seek
clarification. The most common items to be factory finished
are doors, floorings, windows, baseboard, radiation covers,
and grilles. The estimator should keep a sharp eye out to see
that each item of work is figured only once.
Structural steel work often requires painting also. It usu-
ally comes to the job primed, with only touch-up of the
prime coat required. Sometimes, it is delivered unprimed
with the priming done on the job. Touch-up painting is
impossible to figure accurately and depends on the type of
structural system being used, but an average of 5 to 10 per-
cent of the area is usually calculated as the touch-up required.
The structural steel work is taken off by the tonnage of
steel required with the types and sizes of the various mem-
bers required. It must be noted which type of steel is to be
painted: steel joists, rectangular or round tubes, H sections,
or any other type. The shape of the member will influence
the cost considerably. The square footage to be painted per
ton of steel may vary from 150 for large members to 500 sf
for trusses and other light framing methods.
Labor. Subcontractors who specialize in painting and
staining often do this type of work, and they almost always
price it on a lump-sum basis. The time required for painting
and staining is shown in Figure 16.13.
