replace defective materials, parts and equipment and repair related damage.
The drawings are intended to convey the scope of work and indicate general arrangement
and approximate location of apparatus and fixtures, and indicate the general location and
route to be followed by pipes and ducts. Where required installations are not shown on
plans or are only shown diagrammatically, install in such a way as to conserve headroom
and interfere as little as possible with free use or space through which they pass, while
there adequate space is allowed for service, maintenance, repair, or replacement for all
equipment.

Imperial values. Drawings submitted not in conformance with the foregoing will be
rejected.
Where equipment is specified with control panels or electrical control components such
as float switches, control valves, level controllers, relays and the like, provide wiring
diagrams and component descriptions that are specific to the item. General data
covering a wide range of similar devices or components is not acceptable.

equipment is specified under.
Clearly show division of responsibility. No item, equipment or description of work shall be

drawings and approve for dimensions only. In this case guarantee that dimensions will
be worked to and ensure that other sub-trades are aware of these dimensions and shall
comply with them.
Review by Owner and/or Consultant shall be mutually understood to refer to general
design only. If errors in detailed dimensions or interference with work are noticed,
attention of Contractor will be called to such errors of interferences, but

responsibility for said errors or interferences, or from necessity of furnishing such work,
and materials as may be required for completion of work as called for in contract
documents.
This review by the Owner and/or Consultant is for the sole purpose of ascertaining
conformance with the design concept.
This review shall not mean that the Owner/Consultant approved the detail design
inherent in the shop drawings, responsibility for which to remain with the Contractor, and
such review shall not relieve the Contractor of responsibility for errors or omissions in the
shop drawings or responsibility for meeting all requirements of the contract documents.
The Contractor is responsible for dimensions to be confirmed and correlated at the job
site, for information that pertains solely to fabrication processes or to techniques of
construction and installation and for co-ordination of the work of other interfacing Trades
as well as compliance with codes and requirements of Authorities.
