Normal Project Duration NECA #5076-04

This document is an update to an original NECA report, which was published in the early 1980's. New data and information were collected and new methods are presented to provide contractors with additional tools to track productivity using the data in this report as a baseline. Excerpts from the original Normal Project Duration report are used throughout this document. Results shown in this document indicate that electrical contractors are performing work using much shorter durations than 20 years ago. Reductions in project durations were achieved by increasing manpower and using new tools and equipment.

Overtime and Productivity in Electrical Const. NECA #5050-04

The difficulties resulting from overtime work might lead many to question the wisdom of using overtime under any circumstances. There do seem to be compelling reasons for adhering closely to the standard work week whenever possible. However, situations do arise in which there is no alternative to working a longer than standard week. In order to assist its membership in managing these situations, NECA has studied the problems associated with overtime work. This publication embodies the significant conclusions produced by the study and where appropriate, offers recommendations for coping with the issues that arise.

Thermoset FRP Duct Construction Manual

This authoritative manual is one that design engineers, industrial engineering departments, pollution control authorities, fiberglass manufacturers and installation contractors can rely upon for the proper selection, manufacture, and installation of FRP duct systems. The American National Standard (ANSI/SMACNA 011-2017) contains language, tables and details for the construction of hand lay-up, spray-up, and filament-wound FRP ductwork from 30 in. wg negative pressure to 30 in.wg positive pressure. Round Ductwork sizes are expanded to include up to 96 in. diameter. For rectangular ductwork, new duct stiffener tables are added for easier selection. Recognizing the increased popularity of FRP ductwork, this edition is expanded to include commercial/HVAC applications. Supporting this, an underground installation section is added as well as added language on testing and balancing, duct sealing, and duct leakage. Duct hangers and support iinformation have been expanded and organized into a separate chapter which now includes: upper attachments, hanger selection tables, channel (strut) used as trapeze, riser support details, and more. Appendices in this edition cover: extended hanger spacing, general information on safe handling of thermoset fiberglass reinforced plastic duct, and allowable FRP defects.

Establishing Overhead and Burden in a Sheet Metal Business

Sheet metal/HVAC contractors are unique in the construction industry in that they engineer, manufacture and install products made from raw materials. The scope of services provided by sheet metal contracts creates confusion and sometimes conflict with owners and general contractors who may not be familiar with the cost structure of a sheet metal/ HVAC contractor.

The purpose of this document is to detail the various types of expenses incurred by a sheet metal/HVAC contractor in support of a proper determination of overhead and burden rates.

This document is free to members in the SMACNA Store.

OSHA & Regulatory Compliance

OSHA Rule on Silica in Construction

The OSHA rule for silica in construction became effective September 23, 2017 although OSHA included a 30-day “grace period” for full enforcement. SMACNA members affected by this rule are encouraged to take a “holistic” approach to silica compliance by assessing the tasks and processes where silica (found in concrete) is disturbed (cut, drilled, grinded, etc.). SMACNA members should be aware that “Table One” and dust collection tools are not the only options for compliance.

Enhancing Your Organizational Structure: An Approach to Profitable Operations

This white paper focuses on traditional and functional organizational structures. It offers a simple and easily understood contrast and comment on the appropriateness of each approach. In contrast to the traditional structure, the paper concludes that a functional analysis of a firm’s operations can be “a tool for designing their organization going forward. It views a contracting company as a system of various inputs coordinated to create one desired outcome.”

Lean construction methods: efficient work, happy customers

This article describes how lean construction is a way of working that reduces waste, increases efficiency, helps the environment, and allows for working smarter, not harder. But while the concept is one that has unofficially been practiced in the unionized sheet metal industry for years, the ITI is leading an effort to make the concept more standardized in apprentices’ training.

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.
