Steel Decking

Use this CSI 3 part SimpleSpecs™ master specification to specify floor and roof decking.


This section should be edited by or under the supervision of the project’s structural consultant.  Decking should be fabricated to Steel Deck Institute –  SDI Design Manual.


Decking is either fluted or corrugated depending on application and span. Decking is secured to structural framing by welding or mechanically fastening. As a general rule floor decking is galvanized since it will be in contact with concrete. Roof decking is often prime painted but galvanized decking is available where corrosion is expected and to prevent damage in the event of roof leaks, a common occurrence.


Decking can be field cut to length and to accommodate penetrations. Large openings may require supplemental support framing.


Acoustical decking is available that incorporates slots that allow sound to pass through the decking, to be absorbed by the material above the decking.

The SimpleSpecs™ master specs concept
Adding More Words Does Not Make Specifications More Enforceable.    
Design professionals are accustomed to seeing lengthy project specifications, so why is SimpleSpecs™ so short?
Specifications have grown evermore wordy over the years for several reasons:
  1. The mistaken belief that specifications must be lengthy and legal-sounding to be enforceable.  In fact, quite the opposite is true.  Having shorter, easily understood specifications makes us less likely to have problems in the field.
  2. A belief that having lots of words protects us from a Contactor making mistakes.  There is no way to include enough statements to protect yourself from a bad contractor, regardless of the length of your specification.
  3. Our desire to be in control of the project by specifying means and methods instead of including simple, enforceable statements.
Easier to Edit

SimpleSpecs™ is written as a series of Microsoft word files that include statements that affect construction costs or overall quality and are far simpler to edit than other master specification systems.


Each SimpleSpecs™ specification section is non-proprietary and includes three manufacturers that meet the specified reference standards, descriptive, or performance-based requirements. They are written to allow any listed manufacturers to provide the specified products.

Hidden Guide Text

Each SimpleSpecs™ specification section includes hidden text to inform and guide users in editing the specifications to suit project conditions.

Streamlined Editing

SimpleSpecs™ sections are edited using pre-defined options that are contained in [brackets] or by selecting optional text separated by "OR" statements. Paragraph and page numbering are included as automatic codes, eliminating the need to renumber when revisions are made manually.  Global changes to headers, footer, terms, font colors and phrases are easily updated using a third-party search and replace software, available through ZeroDocs.com.
