HVAC Duct Construction Standards - Metal and Flexible

Building on a history of duct construction standards nearly 100 years old, the flagship SMACNA HVAC Duct Construction Standard – Metal & Flexible 4th edition represents the state of the art in the sheet metal duct fabrication and installation requirements. Significant changes for the 4th edition include; flat oval tables for positive/negative pressure applications; spray and aerosolized duct sealants; non-fiberglass duct liner applications; added information on spiral duct fittings; updates to duct hanger requirements; flexible duct hanger spacing and support bracing.

Choosing the Right Metal for Architectural Design

Stainless steel will never corrode or rust. Aluminum is too expensive for many applications. And zinc is quick to deteriorate. L. William “Bill” Zahner III said those beliefs are common among architects and designers in the architectural metals industry. They’re also wrong.

Integrated Project Delivery Guide

This Guide provides an overview of the Integrated Project Delivery (IPD) method from the perspective of sheet metal, HVAC, and mechanical contractors and can serve as a guide for those interested in expanding their market share into healthcare and other IPD market sectors.

IPD is found at the intersection of quality, cost and scheduling on a construction project where project teams, systems, business structures, and practices are all working collaboratively and tapping into the talents and insights of all team members in an effort to optimize efficiencies and reduce redundancies or waste throughout the construction life cycle (e.g., design, fabrication, installation, etc.).

Improving Shop Workflow and Efficiency

Contractors need to analyze ways to improve their current shop layout before investing in any major expansion. With careful examination, you will often discover there is often more unused space available than you first thought.

This updated manual introduces new fabrication approaches and applications to SMACNA shop fabricators to help them become more competitive. The manual assumes members already have a sheet metal shop in operation, and these guidelines are intended to help increase the effectiveness and efficiency of current shop set ups.

The guidelines may also be applied when designing a shop from scratch, as long as the designer knows the basic sequence of the fabrication process. These guidelines are also useful when expanding an existing shop.

What’s in it for me? Documenting the benefits of Lean

Documenting the benefits of Lean admittedly is a challenge, because no two projects are exactly alike. However, we have a substantial body of analysis that suggests the success realized on Lean projects is real and can be duplicated from project to project. This is Part II of a two-part series that explores the benefits and challenges of lean construction.

J.F. Ahern: Prefab Time Lapse Video

J. F. Ahern Co. recently unveiled a time-lapse video that was filmed over several months, chronicling the assembly and installation of 32 multi-trade racking systems for the Froedtert CFAC project in Milwaukee.

J.F. Ahern: What is Prefabrication? Video

In this video, SMACNA member J.F. Ahern takes you through project stages including estimating, pre-planning, design/coordination, scheduling and purchasing, fabrication/assembly, quality control, and field installation to show how prefabrication works and benefits projects though improved risk, timing and cost.
