Likewise, the work to be performed by a particular trade is not necessarily restricted to that of any one division. Any item mentioned under any heading must be supplied even though it is not called for again under the heading for the respective work.

Specific requirements stated in various divisions of the detailed specifications as though applicable to a single item or one unit of work shall also apply to all additional items or units required by the contract and shall not be interpreted as designating that only a single item or one unit is required.

A copy of each referenced publication is on file in the City Engineers Office and is available for inspection by the contractor. However, it is assumed that a contractor experienced in the type of work involved will have his/her own source of access to the referenced publications.

In certain divisions of the detailed specifications, the publications pertaining to the particular divisions are individually listed in this section under the article heading “Abbreviations & Materials by Reference” publisher, full title, basic designation, and specific issue identification. Thereafter, each publication, where used will be referred to only by publisher and basic designation. The abbreviation used elsewhere to denote; the respective publisher is shown in parenthesis following the full name in the listing. Where only the publisher’s abbreviation and basic code number is used alone, with a designated material or test method, it shall be understood that such referenced publication establishes the requirement to be met, complied with or followed, as for examples:
