II. PLANS AND SPECIFICATIONS FOR THE PRESERVATION OF THE CASA GRANDE
RUIN, ARIZONA, 1891

(_Attached to and forming part of contract_)

GENERAL REQUIREMENTS

All the work upon this ruin is to be carried out in such a manner as to
interfere as little as possible with the present condition and
appearance of the building, and the contractors will be held responsible
for any injury to it.

The work is to be carried on under a supervisor, acting for the United
States, who shall have power to reject any materials it is proposed to
use in the work which are not in his judgment equal to those specified,
and he shall have power to have torn down any work done which he has
reason to suspect is not such as required by the specifications, but if
such work shall prove upon inspection to have been well done the
contractor may make a charge of the amount which would have been allowed
for that part of the work had it passed inspection.
