New and Revised Section Synopses: 

New Section 08 7110 (08711) - Basis of Design Door Hardware – Hager

This new proprietary section is based on the products of Hager Hardware and is designed to complement the non-proprietary SpecLink Section 087100 Door Hardware. Hager Companies has been opening the door to innovative products and incomparable customer service since Charles Hager founded the company in 1849. Today, fifth- and sixth-generation Hager descendants still own and operate the business. Hager provides door hardware that spans nine categories and encompasses more than 6,000 products, including:  architectural hinges, Roton continuous-geared hinges, stainless steel continuous hinges, locks, closers, exit devices, trim and auxiliary, thresholds and weatherstripping, and sliding door hardware.

The fundamental concept of this section is that if Hager hardware is acceptable, the easiest way to specify it is proprietarily. On the other hand, this section assumes that the Hager hardware is the "basis of design," meaning that other manufacturers would also be acceptable. To avoid requiring Hager to include all the non-proprietary provisions of Section 08 7100 - Door Hardware, this section references 08 7100 for most of PARTs 1 and 3, and takes the place of most of PART 2 of 087100.  The two sections would be used together, except for situations where the very brief PARTs 1 and 3 would be acceptable, such as for schematic design documents.

The Hager products are organized in the same order as PART 2 of 08 7100, making it easy to see whether any of 08 7100 is also needed — you can "tile" the two sections side-by-side for comparison.  There are links between the two sections, so that when something in one influences the need for something in the other they are coordinated.  For instance, the inclusion of the Hager section automatically includes the statement in 087100 to the effect that Hager is the basis of design (near the beginning of PART 2).

By using both the Hager door hardware section and BSD's non-proprietary section, the specifier can get the best of both -- specific hardware quality and the ease of specifying offered by the "rules" and Hardware Sets presented in 087100 (see article....).

New Section 23 7223 (15785) - Packaged-Air-to-Air Energy Recovery Units

Also known as ERV units, energy recovery units are a type of air-to-air heat exchanger that can transfer both sensible and latent heat through the use of an energy wheel. The energy recovery process is the process of exchanging the energy contained in exhausted building air and using it to treat the incoming outdoor ventilation air in HVAC systems. ERV systems provide a controlled method of ventilating a space, either commercial or residential, by minimizing the amount of energy loss and reducing energy costs. During winter months, heat is transferred from the warmer inside exhaust air to the cold supply air. In the summer, the opposite is true; the inside air cools the incoming supply air.

New Section 26 4300 (16289) - Surge Protective Devices

Field-installed externally mounted or factory-installed internally mounted; 600V and less.

Surge protective device, formerly referred to as transient voltage surge suppressor (TVSS), became the new industry standard term following revisions included in UL 1449 3rd Edition and NEC 2008 Edition. This new section is based on UL 1449 3rd Edition and includes extensive master note content to assist in editing.

Since the desired product ratings and options usually depend on location in the electrical distribution system, this section is arranged based on three separate product applications — for installation at service entrance, distribution, and branch panelboard locations.

SPDs can be specified as either field-installed, externally mounted or factory-installed, internally mounted, or both may be included to allow the contractor to choose. Protection circuits can be specified as either field-replaceable modular or non-modular, or both may be included to allow the contractor to choose. Reasonable median surge current ratings have been included as default choices, with two ratings above and below them as available choices for higher or lower exposure.

New Section 31 6614 (02464) - Hydraulically-Driven Pier Foundations

This new, non-proprietary section covers hydraulically-driven pier foundations, a versatile foundation-repair or retrofit system used to repair or reinforce an existing foundation that has failed or in danger of failing. The system also minimizes the amount of modification to the existing structure and the amount of excavation required. Section 31 6614 offers the user design and capacity options with intelligent linking to the appropriate materials, reference standards, and installation requirements.

Hydraulically-driven pier foundation system components, couplings, and load-transfer devices are designed to meet project-specific requirements, are manufactured from structural steel, and are hot-dip galvanized. These foundations also have the advantages of quick installation in areas of limited clearance and in any weather. Installation is vibration-free (no hammering) and they generate very little spoil (waste soil material) that must be carried away. Load tests are not necessary, as the bearing capacity developed is directly measured by calibrated gauges on the hydraulic driving equipment.

Foundation Supportworks heads up the “Manufacturers” article in this new section and offers a complete line of foundation products for the repair of existing foundation structures as well as deep foundations for new construction. Foundation Supportworks’ in-house engineering staff supervise product design and maintain quality assurance during manufacturing. All manufacturing facilities are ISO 9001 certified. With a network of foundation system manufacturers and installers throughout North America, Foundation Supportworks provides helical pier, helical anchor and resistance pier systems.

Revised Section 26 2200 (16272) - Low-Voltage Transformers (Dry-Type Transformers)

This section has been almost entirely revised to include updated and expanded information. Part 2 organization has been streamlined with the addition of the product article "All Transformers" to consolidate specifications common to all product articles. "Two-Winding Transformers" and "Two-Winding Transformers for Nonlinear Loads" have been renamed "General Purpose Transformers" and "K-Factor Transformers Rated for Nonlinear Loads" respectively. The Autotransformers product article has been deleted (the product article containing buck-boost transformers, which can be configured as autotransformers, remains). Perhaps the greatest improvement in this section, however, is the extensive new master note content, which users should find very helpful in editing the section.

Revised Section 26 2726 (16140) - Wiring Devices

This section has been almost entirely revised to include updated and expanded information. Part 2 product articles have been expanded to include customizable specifications for many common devices, organized into logical groups. Device specifications have been arranged to allow the user to easily include specific product model numbers to establish minimum requirements, a common method due to the lack of standards for quality of wiring devices. The article "Interface with Other Products" has been deleted and its subparagraphs have been relocated. Many of these subparagraphs pertaining to device mounting heights have been grouped together under the installation article along with other paragraphs relating to coordination of outlet boxes for wiring devices. Part 2 also includes two new articles, "Applications" and "All Wiring Devices".

The article "Applications" can be used to specify guidelines for the application of products, such as where certain products are to be used (or not to be used). This article provides a convenient place for this kind of product-related information that often appears in Part 3.

The article "All Wiring Devices" includes a paragraph called "Finishes" that can be used to specify finishes for all wiring devices and associated covers specified in this section. By consolidating finishes in one place, they can quickly be reviewed and edited to suit the project. Using this method, the user avoids having to search through the entire section for finishes specified in multiple locations, possibly missing some occurrences. If using this paragraph, finishes shouldn't be specified elsewhere, such as in product model numbers, in order to avoid conflicts.
