MCAA Magazine   Tema: Juntas de expansión Palabras: Jerry Painter Traducción: Gerardo S. Valerdi   Pregunta: Recientemente obtuvimos un proyecto que incluye revestimiento de ladrillo sobre CMU (Unidades de concreto). Los planos no muestran juntas de expansión y las especificaciones no mencionan nada sobre su ubicación. El Contratista nos dijo que las pusiéramos donde pensáramos que debían ser colocadas. ¿Qué se debe hacer? Primero, hay que revisar la propuesta del ámbito de trabajo y del contrato para asegurarse que nadie se haya metido en el papeleo. Esto es un criterio de diseño y no tu responsabilidad. No tengo una “Guía de reglas de Gibbs” pero si la tuviera, esta regla debería ser de las primeras, sino es que la primera. ¡HAY QUE MANEJAR TODO POR ESCRITO! Esta es una oportunidad ideal para mandar una Solicitud de Información (SDI) al CG (Contratista General). Incluso he tenido a Supervisores de Obra y Contratistas quejándose de que si lo pongo por escrito, “tienen que” responder. Obvio, pues de eso se trata. Las juntas de expansión con revestimiento de ladrillo son parte de un grupo llamado “Juntas de Movimiento”. Estas no tienen mortero y permiten un movimiento diferencial en mampostería. Este movimiento puede ser causado por carga, tensión, compresión, desviación o expansión. En este caso únicamente estamos lidiando con juntas de expansión con revestimiento de ladrillo. Entonces averigüemos sobre el TMS 402-13 también...

Silica 101: Tool Innovation and Compliance

Innovation has played a huge role in the settlement of our country and in how well we live, work and play. More than a century ago, westward expansion was improved with the Conestoga wagon, steamship and railroad. Farmer productivity soared with John Deere’s singing plow and Cyrus McCormick’s mechanical reaper. The Industrial Revolution brought innovation to machines for quarrying and cutting stone. There are those who say the concrete masonry unit (CMU) revitalized the industry, and productivity and safety have been enhanced with advancements in mortar, saw blades, ergonomic design, protective gear and cordless tools. Steve Jobs once quipped:...

The 2015 IBC Will Impact Your Masonry Business. Here’s Why…

Building codes are a strange combination of perceived confliction. In one respect they are constantly changing, forcing the collective construction industry to re-educate themselves under the new provisions every three years. This process is expensive and frustrating, leading to descriptors such as ‘change for change sake’. Yet they are concurrently perceived as being slow to react and resistant to the adoption of new technologies – and when those ‘significant’ changes are implemented, they are generally met with near hostility as designers, contractors, and owners alike struggle to understand why ‘the way things were’ no longer work. I’m generally not...

Build with Strength Campaign Promotes Concrete Products For Buildings

Last year, the National Ready Mixed Concrete Association (NRMCA) launched Build with Strength, a multi-million dollar coordinated industry campaign to educate the building community about the benefits of concrete and concrete products for building construction.

The program is based on significant market research undertaken by NRMCA to better understand the that a great majority...
