substantial construction takes place on the subject project, the
construction inspection services are not contemplated to be needed on
a full-time basis.

preparation,fabrication or manufacture of the materials to be used. The tester will not be authorized
to alter or waive the provisions of the contract or issue instructions contrary to the plans and
specifications already in place. Results of tests will be furnished to Weld County when they have

performed by Engineer should comply more with the quality assurance program already in place in
Weld County, rather than with the full quality control plan utilized by the Colorado Department of
Transportation.
