installation is made in accordance with specifications and drawings and all
safety rules and regulations are observed. In event of conflicts of work on
project with other trades, Contractor to make every reasonable effort to
resolve conflict through meetings and discussions with other parties involved,
by preparation of drawings or other appropriate action. Only after this has
been done shall the Engineer's assistance be requested.
C. When Engineer is requested to visit project to aid in resolution of conflicts or
for witnessing tests,he shall be given a minimum of 48 hours notice'prior to
time his presence is required at job site. �
D. Cost of Engineer's time for general observation or test observ��nce as
described herein is to be borne by Engineer except in those case:; where
Engineer has been requested to visit project and upon visiting finds Co'ntractor
