(b) Plans and Specifications for Bidding

In order to insure adequate and complete bids, plans and sfiecifications accompanying the invitation to bid show:

A complete structural steel design including any detached items, such as loose lintels, clearly showing the work to be performed and giving 5 -172 A ISC Code of Standard Practice I sizes, sections and the relative location of all memliers, floor levels, column centers and offsets, bridge bearing centers and elevations, camber of mem- bers, with sufficient dimensions to convey accurately the quantity and nature of the structural steel, and

2. Wind bracing, moment connections and other si>ecial details, in sufficient detail regarding arrangement of parts, fasteners and welds so that they may be readily understood and supplied.

Plans are made to a scale not less than ¹/₈inch to the foot and the more complex information is furnished to adequate scale.

When the owner* provides the design, [dans and specifixations the fabri- cator and erector are not responsible for the suitability, adequacy or legality of the design; nor is the fabricator resfmnsible for the practicability or safety of erection if the structure is erected by others. If the owner desires the fabricator or erector to prepare the design, plans and specifications or to assume any responsibility for the suitability, adequacy or legality of the design, he dearly states his requirements either in the invitation to bid or on such plans and specifications which accompany it.
