Can the Contractor substitute equipment? When can he do this and what process should be followed?

The Contractor can substitute equipment, upon approval of the Owner in writing.

 

The Contractor shall furnish the complete list of proposed substitutions preferably prior to the signing of the Contract together with such engineering and catalog data as the Owner may require. Thus, the Contractor may furnish the complete list of proposed substitutions even after the signing of the Contract.

 

All requests for substitution of equipment shall be in writing. The Owner will approve or disapprove the request in writing. No substitute equipment shall be used unless approved in writing by the Owner.

 

The Contractor shall abide by the Owner's judgment as to the acceptable proposed substitute equipment.
