,he Contract Drawings and such other drawings as ma %e furnished to the Contractor during the

progress of the Works sha %e considered as iustration %etween the Drawings and the Specificationthe Contractor sha eecute the work in accordance with the decision of the #wner. *f modificationsare necessar the Contractor sha su%mit modifications to the #wner for appro7a %efore suchmodifications are eecuted.

A Drawings and Specification are the propert of the #wner.

,he Contractor wi %e re?uired to gi7e and o%tain a necessar site and other particuars and to agreesuch detais with the #wner. ,he Contractor must aso o%tain detais of an other Contractor"s workaffected % his work and sha work in cose co/operation with a such firms or persons concerned.

,he Contractor sha %e responsi%e for an damage caused to %uidings and contents and works %

,he Contractor sha su%mit to #wner for appro7a %efore the work is commenced a cop of aworking detais and instaation drawings and sha aso supp sufficient copies for the use of the5uider and other interested parties.

,he Contractor must su%mit these drawings as soon as possi%e after the order is paced to gi7e ampe

time for a parties concerned to stud and comment thereon.

,he contractor for a cearance fied conditions maintenance of architectura conditions and properco/ordination sha carefu check the work descri%ed on an working drawings su%mitted with atrades on the o%. ,o this end the contractor during the construction drawing stage sha ensure that heco/ordinates drawings of a other trades that might interfere with the proper instaation of his work.

8o pament sha %e made for an 7ariations or aterations on site due to ack of knowedge of othertrades. An unreso7ed confict %etween trades sha %e referred to the #wner.
