DCA-6: The Unsung Hero of Deck Building - A Missed Opportunity in Code Integration?
In the world of building codes and construction guidelines, the American Wood Council's DCA-6 manual stands out, yet its potential remains largely untapped. This article delves into the underutilization of DCA-6, a guide once regarded as the most sensible blueprint for wood deck construction, and questions why the deck-building industry chose to develop an IRC-specific version instead of lobbying for the inclusion of DCA-6.DCA-6: A Practical Guide Overlooked
Before the IRC (International Residential Code) developed its own section on exterior deck construction, the DCA-6 was the benchmark for deck builders and inspectors, particularly in addressing specific regional challenges, like those in coastal areas. Despite its practicality and alignment with IRC updates, DCA-6 never gained official recognition within the IRC, leading to challenges in its widespread adoption and enforcement.
The Coastal Challenge: A Florida Perspective
In Florida, surrounded by oceanic and brackish environments, deck construction faces unique challenges. DCA-6's specificity, such as the requirement for stainless steel fasteners within 300 feet of the ocean, highlights its adaptability to such environments. This specific guideline is absent in the IRC, underscoring a missed opportunity to address diverse geographical needs within the national code. Florida is not alone in this need, as the United States has over 95,000 miles of oceanfront.
The Early Efforts: Pennsylvania's PCCA and L&I Initiative
Before the IRC included an exterior deck section, organizations like Pennsylvania's PCCA and Department of Labor & Industry, with the involvement of notable industry figures like JAR546, founder of The Building Code Forum, recognized the need for specialized guidance. This led to the development a deck class based on DCA-6, aiming to address deck failures through regional adaptations.
Industry Dynamics and Lobbying Choices
One wonders why the deck-building industry, instead of advocating for the inclusion of DCA-6 in the IRC, chose to develop a version that is more contractor-friendly and perhaps less comprehensive in addressing the diverse environmental challenges across the U.S. This decision potentially overlooked a valuable resource that had already proven its worth in both practical and regional contexts.
The story of DCA-6 in the realm of deck building is one of potential yet unrealized. As we continue to evolve our building practices, it is crucial to revisit and recognize resources like DCA-6, especially when they offer tailored solutions to unique environmental challenges.
