A. D50 Electrical Description

1. UNIFORMAT II definition

• The electrical system of a building distributes and safely energizes building Component Sections or installed equipment from the secondary side of the primary transformer to the building support functions and systems.

2. Major components

• Electrical Service & Distribution (D5010): This subsystem provides for electrical devices that are required to deliver electricity from the primary service distribution transformer to subpanels or equipment. These components include service entrance equipment assembly (underground only ‐ service entrance conductors, conduit and main disconnect), transfer switches, main distribution panel, switchgear, switchboards, branch circuit panels, motor control centers, interior transformers, as well as conduit and wiring from the previous major component to these major components.

• Lighting & Branch Wiring (D5020): This subsystem provides for lighting and branch wiring systems including conduit and wiring from circuit panels to point of service, light fixtures, light switches, receptacles and devices. These components include all types of interior and exterior lighting fixtures including exit lights.

• Communications & Security (D5030): This subsystem includes communication devices and alarm protection systems and is NOT used by the USAF. Communications and security components are not maintained by Civil Engineering. Fire alarm system components are to be inventoried and assessed in D40.

• Other Electrical Services (D5090): This subsystem includes emergency generators and auxilliary fuel tanks, uninterruptible power systems (UPS), and emergency lighting. UPSs are NOT considered real property equipment in the USAF and are NOT inventoried and assessed.

3. Life cycle characteristics

• Electrical systems and components provide reliable service when properly installed, serviced and maintained. These systems have a service life of 30 ‐ 50 years and

4 | P a g e components can remain in service beyond 50 years. These systems and components show relatively slow rates of deterioration, but can accelerate if problems such as improper service/connections, overloading, corrosion, moisture damage, etc. are not addressed in a timely manner. Electrical system components are generally assessed using the Direct Condition Rating (DCR) Definitions chart considering observed defects.

One of the most common problems with building electrical services systems is electrical modifications not complying with the National Electrical Code (NFPA 70) or the National Electrical Safety Code (NFPA 70E).

Consideration of environments (e.g., coastal) may also help with maintaining a safe and properly operating electrical service.

II. Inventory A. General D50 Inventory Guidance

This section presents common UNIFORMAT II D50 Electrical 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 (D50 UNIFORMAT II Minimum Component Reference Table) provides a complete listing of the minimum components inventoried and assessed for D50.

NOTE: Bases may elect to inventory and assess other facility electrical Component Sections. D50 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 (facility acceptance year default from Real Property Assets Database (RPAD)) or to estimate the year installed. 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 determine the year installed. Most switchgear, panelboards, transformers, etc. will have the manufactured year on a data plate. 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.

If this is an initial assessment and no electrical inventory has previously been entered into BUILDERTM SMS, an inventory is required. Most electrical components inventoried for USAF buildings are visible with the exception of facility wiring. When electrical components are not visible (or an area of the building is not accessible), as‐built drawings should be used to identify and quantify the electrical components. If as‐built drawings are not available, the assessor may use experience to make an assumption for the electrical 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 extensive http://www.inspectapedia.com/

5 | P a g e product information available which can help the assessor determine age, equipment type, capacity and/model (e.g. http://www.geindustrial.com ).

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 electrical 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 notes as a guide for data entry by the assessor.

General Electrical D50 Inventory Hints

• If safely accessible be sure to enter the building electrical room to obtain service information and identify main panels and electrical equipment.

• Do not inventory specialty power equipment such as converters, regulators, etc. associated with the building mission or process equipment.

• Do not inventory individual disconnects associated with building mission or process equipment (e.g. food service equipment, etc.).

• Quantity for lighting fixtures refers to number of fixtures, not lamps.

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

B. Inventory D5010 Electrical Service & Distribution Sections

• Electrical service and distribution Component Section inventory for the USAF includes service entrance equipment (underground conduit, conductors and service disconnect assembly); panelboards; switchgear; switchboards; interior distribution transformers; motor control centers; and interior capacitance banks. These components are assemblies and include the conduit and wiring from the previous major component to these major components.

Recommend inventorying “named” components (e.g. LT‐2, P‐3, T‐4, etc.) as individual Component Sections. A Component Section may have multiple components of the same voltage/amperage rating (Component Subtype), Year Installed and condition but list the component names in the Section Details.

Do not use Custom field to describe components. If the drop boxes do not have listed the specific size component needed, give an adequate description in the Section Name, Inventory Comments or Section Details. If the drop box does not have the specific size, select a size from the drop box either smaller or larger that is similar in cost.

Typical electrical and distribution components on USAF bases are:

Uninterruptible power supplies (UPS) and 400 Hz convertors and generators (not emergency power generators) are NOT considered real property equipment and are not inventoried. Electric heating systems, grounding systems, counterpoise systems and lightning protection systems are not on the minimum inventoried component list. Emergency power generators and associated transfer switches and auxiliary fuel tanks may be enclosed in a separate nearby facility(ies) and should be inventoried with the building for which emergency power is provided as needed. Typical other electrical systems components on USAF bases are:

III. Assessment A. General D50 Assessment Guidance

Inventory Notes:

• If desired, collect make, model, serial number

Section Details Section Name: EMER GEN 2 _175KW Fuel may be diesel, LPG, or gasoline

13 | P a g e operability or serviceability (work history).

When electrical 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 (see next page) for major components D5010, D5020 and D5090. The “Rating” reflects observed deterioration, impact on operability, serviceability (work history) and repair requirements based on the chart 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 Index (CI).

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

• Improper construction or installation (Assessor must consider the National Electrical Code (NEC) applicable at time of construction)

• Damage or misuse

• Improper additional circuits or alterations

• Corrosion (often related to weather exposure and/or coastal environment)

• Inadequate Preventive Maintenance (PM)

• Overloading or power surges

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 defects of a system/component, a picture provides a lot of value.

When accomplishing the 5‐year reassessment, especially when it is a different assessor, the assessor can compare the then to now. Even if the same assessor sees a particular asset frequently (possibly yearly during annual PM), the assessor may not notice the gradual degradation so a picture provides great value. Please consult local 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)

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

Below are assessment hint questions to help the assessor determine the most appropriate DCR.

15 | P a g e

B. Assessment D5010 Electrical Service and Distribution Examples of typical electrical service and distribution distresses or conditions include:

D50 Assessment Hint Questions

• What distresses or problems are observed?

• What is the quantity and severity of the distresses?

• Is the electrical 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 for DCR.

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

Based on above:

• 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 a condition that 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, if a significant localized issue needs to be highlighted, which may not necessarily impact the overall Component Section DCR.

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

• The assessor should have 5+ years of experience with building power electrical systems and knowledge of current electrical safety practices and be equivalent to a Journeyman, a V Level Technician or Electrical Engineer. The assessor should be able to identify common electrical system components, understand how they function/operate and have experience planning or performing electrical maintenance, improvements, or repairs.

B. Year Installed

• In some cases, electrical sections may be replaced as an individual repair or partial replacement. These areas would have a different age. The RPAD construction and renovation dates should be confirmed, if they are not appropriate, the component age must be estimated. The building occupants or other facilities staff may be able to provide some information.

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

• Past assessors have developed the below list manufacture dates for commonly found electrical items that can be used to estimate age. These items were probably put in service after date shown below:

o T‐12 Fluorescent Light Fixture 1975 o T‐8 Fluorescent Light Fixture 1981 o T‐5 Fluorescent Light Fixture 1995 (Uses a mini bi‐pin base ‐ cannot be used in a T‐12 or T‐8 fixture) o Compact Fluorescent (CFL) 1995 o High Intensity Discharge (HID) 1995 o Emergency Light 1982

C. Inventory/Assessment

• Typical section names used to describe the major areas of the building include: 1FL,

3. Typical Distress: Animal/Insect Damage

21 | P a g e

2FL, BASEMENT, MEZZANINE, ROOF, WING “X”, etc.

• Typical Section Names used to describe electrical components should be consistent.

Section Names should adequately identify the component inventoried. BUILDERTM SMS dropdown boxes do not have a complete listing of all component sizes available:

o For Panelboards enter Section Name: Panel “xxx”_”xxx/xxx”V_”xxx”A o For Interior Transformers enter Section Name: XFMR “xx”_”xxx/xxx”V_”xxx”KVA o For Main Distribution Panels enter Section Name: MDP”xx”_”xxx”A

• Since dropdown boxes have limited sizes, describe actual size in Section Name and select the next greater size from the dropdown boxes. Avoid using “other.” This will allow BUILDERTM SMS to effectively use all built in processes.

• D5010 – Service Entrance Equipment ‐ Electrical Service and D5020 ‐ Branch Wiring (entered with quantity in square feet) are almost always age‐based because the conduit and wiring cannot be directly assessed. Therefore, DCR assessment, if operable, is entered as “Green.” Exception: If the assessor has other information such as an engineering study, scope of work or occupant complaints indicating electrical problems, the assessor can use professional judgment to select a DCR.

An Inspection Comment should be provided in these cases.

• The D50 items noted below, included in BUILDERTM SMS dropdowns, are not part of the Minimum Component List and typically are not inventoried or assessed but may at the local base’s option except as noted:

o D5010 – Power Converters and Regulators (normally associated with the mission or process vs. the building and are generally not real property) o D5010 – Main Transformers (considered distribution and inventoried/assessed as a Utility) o D5010 – Safety Switches, Enclosed Circuit Breakers and Capacitor

Banks o D5030 ‐ All are owned by Communications Squadron and are NOT real property and are NOT to be inventoried within BUILDERTM o D5090 – Grounding, Grounding points, Lightning protection, Electric Heating and EMCS o D5090 – UPS is NOT real property equipment and NOT to be inventoried

• In buildings with repetitive floor plans (e.g. VOQs, TLFs, dormitories), the assessor may use judgment and inventory and assess a representative sample of each room type and section, then estimate the quantity of repetitive items such as lights.

V. Inventory/Assessment Data Collection Sheets The following data collection forms are included as a recommendation and may 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. D50 Uniformat Minimum Component 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 SMS but should not be more often than an annual assessment.

AMP reflect the AMP to which the component is assigned:

F: Facility AMP
