E. Complete and Safe Demolition Site
It is the intent of this specification to require demolition work that brings the site clear of
buildings, structures, equipment, and utility services, but to retain impervious surfaces in
order to prevent ground erosion to occur. Also the intent is to leave the site safe from
tripping hazards, protrusions that could cause harm, and depressions that would be walking
hazards. Once the demolition work is complete the surface of the site shall be safe and non-
erodable. All spoils from the demolition work shall be removed from the site by the
Contractor. Bid pricing shall reflect these requirement. It is not possible to specify or
describe every detail of work required to complete a project of this nature or to predict
problems that might be encountered. The successful Contractor will be required to provide
all labor, equipment, tools, specified material, and incidental items necessary to undertake
the demolition work and complete the project, as described herein, resulting in fully
prepared and functional sites that perform to their intended purposes. Minor omissions
from the specification or drawings shall not relieve the Contractor from the obligation to
provide the completed project that is fully functional as intended by the Owner. Failure of
this specification to describe each detail or incidental item necessary to a complete and
functional project shall not entitle the Contractor to additional charges. Examples of items
that will not be considered as basis for claims for additional cost are, but shall not be limited
to, minor relocations, minor changes in the demolition plan, differences in the actual
surface of the site from that shown on the demolition plan, reasonable weather delays, site
cleanup, etc. Further, all work shall be performed and completed in a thorough, safe, and
workmanlike manner and shall follow the best modern recognized practices,
notwithstanding any omissions from this specification.
