Standard Steel Doors and Frames for Modular Masonry Construction

- Jan 28, 2019-

The Module

Definition:

The size of some one part, taken as a unit of measure for regular proportion. A basic unit of

measure adopted by the Building Industry as 4 inches.

Concept:

Use of a standard multiple dimension common to dimensional building products improves

finished structure by the following:

A. Increased accuracy, legibility, and simplicity of working drawings and contract documents.

B. Reduced drafting time (up to 25%).

C. Reduction of architect/contractor conflict caused by ambiguous details.

D. Added aesthetic flexibility induced by small unit standardization, allowing freedom of architectural

design.

E. Increased flexibility of finished structure through lower modification, addition, and renovation

costs.

F. Reduced overall material and labor costs by facilitating the use of standard practices and

definable operating procedures.

Engineering:

A. Theory of modular construction reduces “field” measurements. (Practical considerations do

not allow complete elimination; however, a considerable reduction in job dimensioning requirements

will result.)

B. Interchangeability and substitution of materials is facilitated by the elimination of redimensioning

when two modular components are switched.

C. Estimating and takeoff simplified.

D. Detailing and drawing coordination between trades and specialties simplified by small size

standard grid.

Aesthetics:

A. Modular masonry construction meets the architectural need for blending and continuity of components.

Non-modular units interrupt a geometric pattern, or flow, by virtue of the discontinuity

of line necessary for their installation.

B. As a specific case, the use of a butted frame (Modular) is extremely important in stack bonded

masonry unit construction. Any interruptions, such as cut units, unit lintels, wrap-arounds, etc.,

destroy the strong linear function of such details.
