07613 (07 1613) BSD - Polymer Modified Cement Waterproofing:
Portland cement-based thick coating; positive or negative side; potable water contact. This is a slurry or trowelable coating for application to concrete, masonry, and stucco surfaces. It can be used on the inside (“negative”) side of structures that must resist hydrostatic pressure without spalling or delaminating due to the vapor pressure through the substrate. This makes it ideal for repairing leaky underground structures because excavation is not required. Active (running) leaks must be repaired or stopped by using a special-purpose leak plugger, not the cement-based waterproofing. Less stringent applications are mostly on the “positive” side, for protection of cementitious substrates from weather, water, and atmospheric damage. It is a principal method of curing leaky masonry walls, provided the leaks are not due to moving joints. For structural concrete, this waterproofing improves resistance to carbonation (gradual deterioration due to diffusion of carbon dioxide into the concrete) and alkali-silica reaction (ASR), also known as alkaline aggregate reactivity (AAR) (by preventing water contact, the main catalyst).
Although not a new product, there are no accepted industry standards for chemical composition; each product is essentially a proprietary mixture. For critical performance applications, such as high hydrostatic pressure, test results should be requested and evaluated.
07825 (07 8205) BSD - Board and Blanket Fireproofing:
Calcium silicate, mineral fiber, and ceramic fiber boards; flexible blankets for duct protection. These are fireproofing types other than those that are sprayed or “painted” on, usually for concealed applications. There is an extremely limited selection of products and manufacturers, and very few fire tested assemblies. Before specifying, be sure that the hourly ratings needed are available for the specific assembly to be protected. Also, verify that the products and tested assemblies needed are acceptable to the authorities having jurisdiction. The use of blanket fireproofing for grease and ventilation ducts is a relatively new development which may not be familiar to code authorities.
10671 (10 5613) BSD - Metal Storage Shelving:
Four post, case-type, and cantilever style; metal shelving, freestanding or fixed to the floor, wall, or ceiling, for storage of stock, books, papers, and archives, as well as for office and library applications. Four post shelving is primarily used for stockrooms, warehouses, archives, and other out-of-sight storage; case and cantilever shelving are most often used in offices and libraries. Design, selection, and specification information provided by The Material Handling Industry of America can be found at www.mhia.org.
10672 (10 5623) BSD - Wire Storage Shelving:
Coated wire closet shelving; associated laminate shelves; used primarily in residential applications, for clothes closets, linen closets, etc. They are not intended for heavy duty storage, especially not for books or paper. The shelves are typically mounted directly to the wall with end-wall supports; use wall-mounted standards with cantilever brackets wherever shelf end support is not possible.
10673 (10 5617) BSD - Wall Mounted Standards and Shelving:
Residential and commercial; optional custom-made wood, glass, and laminate shelves; wall mounted cantilevered shelving for display or storage in residential, office, or light duty retail settings. Slotted standards are mounted to the wall, and adjustable brackets support the shelves. The brackets may be fixed or folding. Although this style of standards is very widely used, as of 11/1/04, the only known U.S. manufacturer is Knape & Vogt Manufacturing Company, www.knapeandvogt.com. Specifying may be simplified by including K&V’s model numbers.
15731 (23 8127) BSD - Small Split-System Heating and Cooling:
Matched indoor and outdoor units; furnaces, AC, air- and water-source heat pumps; optional ductless mini-splits; residential-sized ducted systems that can also be used in non-residential applications. Furnaces include natural gas, propane, heating oil (No. 1 & 2), and electric. Cooling is accomplished by either direct-expansion refrigeration or heat pumps. Heat pumps can be used for both heating and cooling, with optional electric heat. Heat pumps are either air-source (like standard condensing units) or water-source. In this application the water-source would normally be a ground water heat exchanger or open water source. The water source, piping, pumps, and other equipment must be specified elsewhere.
15741 (23 8149) BSD - Water-to-Water Heat Pumps:
Water source heat pumps with refrigerant-to-water condensers and
evaporators; used to control the temperature of a “load-side” hydronic
piping system, or as a heat recovery device on a hydronic system. Terminal
units can include hydronic baseboard heating, fan-coil units and convectors,
radiant slab heating, and snow melting. The system could also be designed
to serve multiple terminal heat pumps. In the case of hydronic loop
control, the water source is either a closed-loop ground-coupled
(geothermal) heat exchanger, or boilers and chillers linked in a
heat-exchanging piping loop. System design information may be found in
ASHRAE’s Commercial/Institutional Ground-Source Heat Pump Engineering
Manual, IGSHPA’s manuals, or at the FEMP/Energy Star website at
Circulator pumps for the source-side loop are commonly made by the heat pump manufacturer, and can be specified here or in Section 15188 (23 2123) - Hydronic Pumps.
