Rilem Tube Extended

By:  Gil Castonquay    

In this segment we'll focus on the "Rilem Tube" test method.  If this were a full length article, we certainly would get into a more detailed background as to how the test came to be, such as how RILEM originated in France and is actually an acronym for Réunion Internationale des Laboratoires et Experts des Matériaux, and is conducted per the RILEM Commission 25, PEM, Test Method 1154, but, for the purpose of this blog, for brevity sake, we'll just cover some of the high points to provide a brief overview as to how and why this test method, this tool, should be a part of your diagnostic approach tool bag when evaluating building enclosure performance.

AAMA 501.2 Testing as an Instrument of Effective New Construction Quality Control Programs

By: Craig Andrade

AAMA 501.2 Testing, sometimes referred to as “Monarch Testing” or “Hose Testing”, is a practical and cost efficient method of assuring the watertight installation of fenestration and cladding systems, for new construction as a quality control measure and for existing construction as a diagnostic tool.  For brevity sake, this blog pertains to the benefits that can be employed during a new construction project.   

Calculating Composite Production Values for Multi-Item Assemblies

By:  Charles B. Antone

In the following brief, I will show the underlining governing equation for calculating composite production values for multi-item assemblies.  A multi-item assembly can be represented in a multitude of forms, but in this discussion I will focus primarily on calculating production based construction cost estimates. Once understood, the composite production value underlining equation can be used forensically, as well as as a means to track the real-time labor usage on an active construction site.
