This is optional for Army projects. Use materials or products extracted, harvested, or recovered, as well as manufactured, within a [800] [_____] km [500] [_____] mile radius from the project site, if available from a minimum of three sources. 1.2.1.2 _{Environmental Data} NOTE: ASTM E 2129 provides for detailed documentation of the sustainability aspects of products used in the project. This level of detail may be useful to the Contractor, Government, building occupants, or the public in assessing the sustainability of these products. This is optional for Army projects. [Submit Table 1 of ASTM E 2129 for the following products: [_____].] 1.2.2 Performance Requirements 1.2.2.1 Cathodic Protection and Pipe Joint Bonding Provide cathodic protection and pipe joint bonding systems in accordance with [Section 26 42 14.00 10 CATHODIC PROTECTION SYSTEM (SACRIFICIAL ANODE)] [and] [Section 26 42 17.00 10 CATHODIC PROTECTION SYSTEM (IMPRESSED CURRENT)] [Section 26 42 13.00 20 CATHODIC PROTECTION BY GALVANIC ANODE] [and] [Section 26 42 19.00 20 CATHODIC PROTECTION BY IMPRESSED CURRENT]Section 26 42 13.00 40 CATHODIC PROTECTION and Section 26 42 19.00 40 CATHODIC PROTECTION SYSTEM (IMPRESSED CURRENT). 1.2.2.2 Plumbing Fixtures Water flow and consumption rates shall, at a minimum, comply with requirements in PL 102-486. 1.2.3 Accessibility of Equipment NOTE: The following requirement is intended to solicit the installer's help in the prudent location of equipment when he has some control over locations. However, designers should not rely on it at all since enforcing this requirement in the field would be difficult. Therefore, the system designer needs to layout and indicate the locations of equipment, control devices, and access doors so that most of the accessibility questions are resolved inexpensively during design. Install all work so that parts requiring periodic inspection, operation, maintenance, and repair are readily accessible. Install concealed valves, and equipment requiring access, in locations freely accessible through access doors. 1.3 SUBMITTALS NOTE: Review submittal description (SD) definitions in Section 01 33 00 SUBMITTAL PROCEDURES and edit the following list to reflect only the submittals required for the project. Submittals should be kept to the minimum required for adequate quality control. A “G” following a submittal item indicates that the submittal requires Government approval. Some submittals are already marked with a “G”. Only delete an existing “G” if the submittal item is not complex and can be reviewed through the Contractor’s Quality Control system. Only add a “G” if the submittal is sufficiently important or complex in context of the project. For submittals requiring Government approval on Army projects, a code of up to three characters within the submittal tags may be used following the "G" designation to indicate the approving authority. Codes for Army projects using the Resident Management System (RMS) are: "AE" for Architect-Engineer; "DO" for District Office (Engineering Division or other organization in the District Office); "AO" for Area Office; "RO" for Resident Office; and "PO" for Project Office. Codes following the "G" typically are not used for Navy, Air Force, and NASA projects. Choose the first bracketed item for Navy, Air Force and NASA projects, or choose the second bracketed item for Army projects. Government approval is required for submittals with a "G" designation; submittals not having a "G" designation are for [Contractor Quality Control approval.] [information only.

Installed fixtures and systems should be life-cycle cost-effective. Low-flow and zero-flow fixtures and accessories (such as waterless urinals and sensor operators) may require special training. Because these technologies may be different from the systems and materials with which the Government personnel are familiar, education about the environmental qualities as well as the operation and maintenance requirements may be necessary. Refer to Section 01 45 01.10 USACE Quality Control System (QCS) and 01 45 01 USACE Quality Control for USACE projects, 01 45 02.10 NAVFAC Quality Control for Minor Construction and/or 01 45 02 NAVFAC Quality Control for Navy projects, 01 45 04 NASA Quality Control for NASA projects. Reducing potable water consumption and wastewater discharge in buildings contributes to the following LEED credits: WE2; WE3. Water quality for most buildings is largely determined by the municipal water treatment facility. Most water treatment facilities rely upon chemicals, including chlorine, to combat pathogens. Chlorine is highly reactive and readily forms chlorinated compounds, many of which are considered to be dangerous. Chlorinated hydrocarbons, such as DDT, have been and are used as pesticides. If this is a concern for a given location, include the bracketed chlorine filter requirement in the lavatory, sink, cooler, shower and bathtub specification paragraphs below. The ARMY and the NAVY do not provide chlorine filters to their domestic water outlets. These paragraphs cover fixtures most often specified. The selection of fixture requirements is based on MIL-STD-1691 to the most practicable extent. The fixture listing will be revised for each project by deleting inapplicable items. The various types of fixtures will be identified by corresponding mark numbers shown on the drawings. A maximum of acceptable fixture and trim options should be allowed for materials in this specification, unless life cycle analysis or local experience indicates that one type of material is better suited than others. Use separate hot and cold water valves.
