A. D20 Plumbing Description

1. UNIFORMAT II definition

• The plumbing system of a building provides the supply and distribution of potable water and the removal of waterborne/sanitary wastes and roof rainwater (interior piping). The system includes piping and fixtures for safe distribution and waste removal, and may include energized equipment for heat transfer, water heating, washing or pumping. The system may also contain control valves, relief valves, filters and conditioners. The system is designed to support the function/mission of the building and for comfort and safety of the occupants.

2. Major components

• Plumbing Fixtures (D2010) – A receptor or device having both a water supply connection and a discharge to the drainage system such as toilets, lavatories, showers and sinks.

• Domestic Water Distribution (D2020): The system of pipes, tanks, pumps, filters and water conditioning appliances used for the supply, distribution, heating and filtering of potable water within a building.

• Sanitary Waste (D2030): The system of drain, waste and vent pipes that removes sanitary waste and grey‐water from a building and vents the gases produced by the waste.

Inventory and assessment is optional.

• Rain Water Drainage (D2040): The piping system within a building (interior) for the removal of rain water collected on the roof. Inventory and assessment is optional.

• Other Plumbing Systems (D2090): Specialty pipe, equipment or appliances that are not part of the potable water distribution system or the drain‐waste‐vent system. Inventory and assessment is optional.

3. Lifecycle characteristics

• Plumbing systems and components provide reliable service when properly designed, installed, serviced and maintained. These systems generally have a range of service life from 20 ‐ 40 years with plumbing fixtures at the low end of the range and industrial/ commercial domestic water heating systems at the high end of the range, if properly maintained. Since plumbing systems are relatively short‐lived components, they are

4 | P a g e assessed using the Direct Condition Rating (DCR) Definitions chart considering observed defects.

Plumbing fixtures, with accompanying faucets and drain assemblies, have an expected service life of 20 years. This life is greatly affected by use and the maintenance they receive. Fixtures in high/rough use areas will require renewal/replacement in less than 20 years. Fixtures that are well maintained may see a service life beyond 20 years.

Residential style water heaters and equipment used in a light commercial environment have an estimated service life of 20 years, while heavier commercial grade hot water heaters and heat exchangers have an estimated life of 30 to 40 years.

Piping systems for domestic water and waste/vent piping, if properly installed and insulated (when required), are considered to have a service life beyond 40 years.

One of the most common problems with plumbing systems is that, over time, building mission, equipment and occupancy change. These changes often require plumbing system alterations, additional piping and new fixtures that can result in an overloaded building sanitary waste system, code issues and inaccurate plumbing as‐built drawings.

II. Inventory A. General D20 Inventory Guidance

This section presents common UNIFORMAT II D20 plumbing inventory component sections found across USAF installations as a guide for entering into the BUILDERTM SMS or BREDTM software. Inventory items are arranged by BUILDERTM SMS system with Equipment Category, Component Subtype, Quantity and Inventory Notes. Each building’s full or partial inventory can be captured in the field using the Inventory/ Assessment Data Collection Sheet(s) included in Section V and in the AFCEC BUILDERTM SharePoint Site Documents Library. Section VI (D20 UNIFOMRAT II Minimum Component Reference Table) provides a complete listing of the minimum components inventoried and assessed for D20 for the USAF.

NOTE: Bases may elect to inventory and assess other facility plumbing Component Sections. D20 Inventory and assessment is required by the current AFCAMP Playbook (Business Rules) as project support documentation for consideration in the project prioritization process. All components included in the project Statement of Work require inventory and assessment.

Component Subtypes General, Other, and Unknown require a Section Name to identify the Component Sections. Include additional information in Inventory Comments if required to further describe the Component Sections.

It is critical to confirm the year installed (default from Real Property Assets Database (RPAD)) or to determine the year installed for each component. BUILDERTM SMS uses the Install Date, life cycle degradation curves and assessment observations to establish Condition Index (CI) for each Component Section. If the assessor suspects the RPAD default date is not accurate or an addition or renovation has taken place check the RPAD record for year renovated or check local as‐built or renovation drawings to help estimate the year installed. Estimated Install Dates decrease the Expected Service Life significantly. Every effort should be made to establish an Install Date and avoid the use of estimated.

5 | P a g e

If this is an initial assessment and no plumbing inventory has previously been entered into BUILDERTM SMS, an inventory is required. Most plumbing components inventoried for USAF buildings are visible with exception of piping and ductwork components. When plumbing components are not visible (or an area of the building is not accessible), as‐built drawings should be used to identify and quantify the plumbing components. If as‐built drawings are not available, the assessor may use experience to make an estimate for the plumbing component types and quantities based on similar construction, consultation with local staff and other resources such as http://www.inspectapedia.com. Often manufacturer websites will have product information available which can help the assessor determine age, equipment type, capacity and model.

BREDTM currently has an inventory data field “NOT Energy Efficient: Yes/No” used by Defense Logistics Agency (DLA). The field is not currently used by the Air Force. The checkbox is currently just a "flag" to let DLA know a more thorough Level 2 Energy Audit is suggested. The Standard Report simply checks if any sections in the building were flagged. If a section is flagged, the report suggests the building receive a Level 2 Energy Audit and estimates a cost for the audit based on the facility square footage.

The flag appears in the report under “Efficiency and Obsolescence.”

The remainder of this section provides photo examples of the most common USAF plumbing inventory items categorized by major components, and accompanied with appropriate Equipment Category, Component Subtype and Quantity from the BREDTM drop down menus. This information is supplemented with general and specific inventory hints as a guide for data entry by the assessor.

B. Inventory D2010 Plumbing Fixtures Plumbing fixture inventory is a systematic count of building plumbing fixtures such as showers, toilet fixtures (water closets), lavatories, sinks, etc.

Typical plumbing fixture components on USAF installations:

General Plumbing D20 Inventory Hints

• Assessors for D20 Plumbing and D30 HVAC work closely together. These systems have some similar components. Storage tanks, pumps and piping used for domestic water are covered under D20 Plumbing. Boilers are not covered in D20.

• Backflow preventers for Fire Protection systems are recorded under D40 Fire Protection. Others are recorded under D20 Plumbing; record size.

• Find pump, backflow and other major equipment nameplates for make, model, serial number, and capacity and enter into Section Details.

• Inventory Comments should be recorded to clarify inventory component description if Section Name is insufficient.

III. Assessment A. General D20 Assessment Guidance

Plumbing Component Sections are assessed using Direct Condition Rating (DCR). Most plumbing Component Sections will be visible. When Component Sections are not visible, assessment is based on operability or serviceability (work history).

When plumbing Component Sections are visible, they must be assessed. The on‐site assessment is determined based on the assessor’s observations compared to the Direct Condition Rating (DCR) Definitions chart for major components D2010, D2020, D2030 and D2040. The “Rating” reflects observed deterioration, impact on operation, serviceability (work history), and repair requirements based on the chart (next page), and the assessor’s professional judgment. When determining the “Rating,” the assessor should consider the quantity and severity of conditions or distresses observed. The assessor must provide an Inspection Comment in cases of Amber+ or lower DCR or BUILDERTM calculated Distress Survey rating. It is highly recommended that photographs documenting defects to be taken and attached to the assessment.

If an otherwise operational component cannot be maintained in the future due to the non‐availability of repair parts, the component should be rated no higher than ”Amber +.”

Under no circumstances should age be factored into a DCR or Distress Survey assessment. Ratings are based on condition, operability and/or serviceability only. BUILDERTM SMS already factors in the age from the Install date when BUILDERTM SMS calculates condition.

The following conditions or events can accelerate plumbing component deterioration and should be considered by the assessor:

• Improper construction or installation

• Damage or misuse

• Corrosion

1. Equipment Category: D204001 Pipe & Fittings

Component Subtype: General

Quantity: LF Year installed/Renewed: EST

Inventory Notes:

Typically cast iron, bell & spigot in older buildings, no hub band in newer buildings May also be plastic Section Name: Rain Water Drain – Interior

20 | P a g e

• Lack of preventive maintenance

• Water treatment issues

• Environmental factors due to hard water or other dissolved solids in the water supply

Boiler and Unfired Pressure Vessels are inventoried in D30 – HVAC. Refer to that section.

If observed, the assessor must consider the severity and density of these conditions to determine the DCR provided by the following DCR chart.

The assessor must provide an Inspection Comment for any Amber+ or lower DCR or BUILDERTM calculated Distress Survey rating. Unless the condition is based on serviceability, compliance, or a condition that cannot be visually documented, photograph documentation is highly recommended to be attached to the assessment.

When there is visible deterioration or defect of a system/component, a photo provides a lot of value.

When accomplishing the 5‐year reassessment, especially when it is a different assessor, record photos allow the assessor to compare current conditions to past conditions. Even if the same assessor sees a particular asset frequently (possibly yearly during annual PM), the assessor may not notice the gradual degradation. A photo provides great value. Please consult local Information System Security Officer (ISSO) for correct procedures on taking pictures, reviewing picture content and transferring data to AFNET to ensure INFOSEC, COMSEC, OPSEC compliance.

Following the BUILDERTM SMS assessment, the assessor should inform the facility manager of any new issues discovered.

NOTE: Red highlighted text is provided as an example of a life cycle of typical components and should be adjusted as needed to represent other various components.

Direct Condition Rating (DCR) Definitions

Rating Observation Green (+)

Fully Operational ‐ Free of Known or Observable Defects Keep doing PM required to maintain warranty ‐ no action required

Green Fully Operational ‐ Slight Deterioration or Minimal wear Keep doing PM ‐ no action required

Green (‐) Fully Operational – Normal wear and/or serviceability defects Keep doing PM ‐ need to start planning for rehabilitation

Amber (+) Reduced Operation – Minor wear and/or serviceability defects Repairs could be accomplished and replacement planned within next eight to ten years (Investment of resources could extend life)

Amber Reduced Operation – Moderate wear and/or serviceability defects Repairs could be accomplished and replacement planned within next six to seven years (Investment of resources could extend life)

21 | P a g e

Direct Condition Rating (DCR) Definitions

Rating Observation Amber (‐) Reduced Operation – Significant wear and/or serviceability defects

Repairs could be accomplished and replacement planned within next three to five years (Investment of resources could extend life)

Red (+) Loss of Operation – Moderate wear and/or serviceability failure Repairs could be accomplished and replacement planned within next two years (Run to failure ‐ further investment unwise)

Red Loss of Operation – Significant wear and/or serviceability failure Repairs could be accomplished and replacement planned within the next year (Run to failure ‐ further investment unwise)

Red (‐) Loss of Operation – Complete wear and/or serviceability failure Replacement needs to be planned immediately

Some thought may be required regarding deterioration and operational loss along with level of repair.

Total operational loss may occur due to failure of some minor subcomponent in the assembly. In these cases the overall component section condition may be “Green” when only a minor fix will correct the problem.

Below are assessment hint questions to help the assessor determine the most appropriate DCR and examples of common distresses.

22 | P a g e

B. Assessment D2010 Plumbing Fixtures Note: A large building will have a significant number of plumbing fixtures; the assessor should use judgment in assigning the “Rating” based on the overall condition of fixtures of a specific Component Section. Do not assign a low rating based on a single damaged fixture. Consider entering a defective fixture(s) as a separate Component Section(s).

Examples of typical plumbing fixture distresses or conditions include:

D20 Assessment Hint Questions

• What conditions or problems are observed?

• What is the quantity and severity of the distresses?

• Is the plumbing system/component operating properly?

• What is the service/repair history of the component?

• Are repair parts readily available for the component?

• Is there a compliance issue? Refer to the BUILDERTM Direct Condition Rating

Matrix in the AFCAMP Playbook for DCR.

• Will repairs preserve or extend the remaining service life of the component?

Based on above:

• What are the SRM needs for preventive maintenance, repairs, rehabilitation, or replacement? (See DCR definitions chart).

• Is serviceability or reliability reduced? (See DCR definitions chart).

• Select a DCR from the chart.

• If assessment “Rating” is Amber + or below, enter an Inspection Comment to describe the reason. Unless the condition is based on operability, serviceability, compliance, or condition cannot be visually documented, photograph documentation of the defect(s) is highly recommended to be attached to the assessment.

• An Inspection Comment should also be entered regardless of DCR or Distress Survey rating if a significant localized issue needs to be highlighted, which may not necessarily impact the overall Component Section rating.

F. Assessment D2090 Other Plumbing Systems Sections There are no D2090 components currently inventoried or assessed.

IV. Inventory and Assessment Rules of Thumb A. Assessor Qualifications

• The assessor should have 5+ years of experience related to building plumbing systems or be equivalent to a Journeyman, Level V Technician, Civil or Mechanical Engineer. The assessor should be able to identify common plumbing system components, including domestic water systems. The assessor should understand how plumbing systems operate, and have experience with planning and/or performing maintenance, repair or replacement of the systems.

B. Year Installed

• In some cases plumbing sections may be replaced as an individual repair or partial replacement. These areas would have a different age. The Real Property Database (RPAD) construction and renovation dates should be confirmed. If they are not appropriate, the component age must be estimated. The building facility manager, occupants or shop staff may be able to provide some information.

• Additions, new wings or major renovations likely require identifying a separate plumbing section with a different age.

• Toilets: Low flow toilets, 1.6 gallons per flush (gpf) and urinals, 1 gpf, date from the mid – 1990’s when water conservation was federally mandated. The fixture will be stamped 1.6 gpf or 1 gpf accordingly. WaterSens labeled flushometer‐valve toilets, whether single or dual flush, use no more than 1.28 gpf.

• Toilets: Toilets often have the date of manufacture embossed or stamped in the tank just under the lid.

• Water Heaters: Most water heaters have the date of manufacture coded into the serial number. For date decoding check:

1. Typical Distress: Ponding due to Clogged Roof Drain

27 | P a g e http://www.rmnahi.org/WaterHeaterSerialNumberDecoder.pdf and http://www.fastwaterheater.com/waterheatermodels.asp. and for Lochinvar:

http://www.lochinvar.com/linefiles/WARR‐14.pdf

• Water Distribution Pipe: Galvanized pipe was used through the 1950’s. Copper came into use in the 1960’s and is still used today. Plastic (PVC, CPVC and PE) came into use in the 1970’s and is still used today.

• Sanitary Waste: Bell & Spigot cast iron pipe (3” and up) with galvanized pipe branches (1‐1/4” to 2”) was used through the 1950’s. Copper came into use in the 1960’s and is still used today though not often due to cost. Plastic (PVC white and ABS black) pipe came into use around 1970. Many commercial buildings today are piped with cast iron No Hub Band.

C. Inventory/Assessment

• Typical section names used to describe the major areas of the building include: 1FL, 2FL, BASEMENT, MEZZANINE, ROOF, WING “X”, etc.

• Typical Section Names used to describe plumbing components may be used where capacity is not included in the BUILDERTM SMS dropdown or a unique component exists such as PUMP‐1, etc.

• An emergency eyewash and safety shower combination unit count as both an eyewash and a safety shower.

• A combination tub and shower unit count as both a tub and a shower.

• Do not inventory:

o Water heaters less than 20 gallons o Point of use (flash) water heaters o Floor mounted (free standing) water coolers o Small (less than 5 gallon) expansion tanks o Plastic (fiberglass) laundry sinks o Washer hook‐ups (include in piping estimate) o Free standing fixtures that serve the mission not the building such as kitchen 3 compartment sinks, galley steam kettles, scullery dishwashers, clothes washers o Air compressors

• Kitchen Sinks are often double bowl which is not an option in BUILDERTM SMS. Add an Inventory Comment indicating the unit is a single or double bowl.

• ABS (black plastic drain, waste, vent pipe) is not an option in BUILDERTM SMS. Enter as PVC (white plastic DWV pipe) as these are similar in cost and longevity.

• Group Shower – Two or more shower fixtures in a common shower room (often ceramic tile) are considered a group shower with the quantity being the number of shower heads and finish for example: “This is a 6 shower head, ceramic tile, group shower”.

• Very large hot water tanks can be water heaters or hot water storage tanks. A water heater will have a pair of steam or hot water pipes entering the tank into a shell and tube heat exchanger to transfer heat to the water in the tank, as well as an inlet and outlet pipe. A hot water storage tank will only have an inlet and outlet pipe.

• Large Tank Volume: For large water heater tanks or storage tanks the volume can http://www.rmnahi.org/WaterHeaterSerialNumberDecoder.pdf http://www.fastwaterheater.com/waterheatermodels.asp http://www.fastwaterheater.com/waterheatermodels.asp http://www.lochinvar.com/_linefiles/WARR

• Even though boilers can provide domestic hot water or heating hot water; they are all entered in D30. Check for labeling on the unit or the piping and coordinate with assessor covering D30 HVAC.

V. Inventory / Assessment Data Collection Sheets The following data collection forms are included as a recommendation and may also be found in the AFCEC BUILDERTM SharePoint Site Documents Library. Many assessors also use floor plans or a notebook. Use whatever collection method works best for the individual assessor.

VI. D20 UNIFORMAT II Reference Table The following table provides SMS MINIMUM inventory and condition assessment requirements.

The table effectively provides a list of WHAT will be inventoried, WHERE within the SMS the component inventory will reside and HOW a component is to be condition assessed. The structure of the list is within UNIFORMAT II to be consistent with BUILDERTM SMS. Currently all components are Direct Condition Rating assessed. Eventually, Distress Survey assessments may be conducted on selective components.

PM Inspection/Testing Directive column gives information on any Air Force applicable publication providing Preventative Maintenance (PM) actions that, once conducted, provides information on a component's condition assessment. Preventive Maintenance Task Lists (PMTLs) or other inspections may be considered a Distress Survey type assessment in the future for some components.

Condition assessment frequency is not to exceed 5 years. Condition assessments conducted as part of a PMTL may be entered into the SMS but should not be more often than an annual assessment.

AMP reflects the AMP to which the component is assigned:
