A. D10 Conveying Systems Description

1. UNIFORMAT II definition

• Conveying Systems are automated or manual systems that provide vertical or horizontal personnel, equipment or material movement. Systems include elevators, accessibility lifts, escalators, chutes or built‐cranes/hoists.

2. Major components

• Elevators & Lifts (D1010) – Includes personnel elevators, freight elevators and accessibility lifts.

• Escalators & Moving Walks (D1020) – Includes escalators used to move personnel vertically and moving walkways used to move horizontally.

• Other Conveying Systems (D1090) – Includes built‐in material lifting devices such as jib booms, double beam cranes and dumbwaiters, as well as chutes (linen, refuse, etc.).

3. Lifecycle characteristics

• Conveying System components are generally built‐in items with operating or moveable parts that require routine inspection, preventive maintenance and service. These items are typically short‐lived components that can show accelerated deterioration if not properly maintained or used inappropriately.

II. Inventory A. General D10 Inventory Guidance

This section presents common UNIFORMAT II D10 Conveying Systems 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 Field Data Sheet(s) included in Section V and in the AFCEC BUILDER SharePoint Site Documents Library.

NOTE: Currently, there are no minimum components inventoried and assessed for BUILDERTM SMS inventory for D10 for the USAF. Bases may elect to inventory and assess conveying system components. D10 Inventory and assessment is NOT required by the current AFCAMP Playbook (Business Rules) as project support documentation for consideration in the project prioritization process. However, 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 estimate the year installed. BUILDERTM SMS uses the Install Date, life cycle degradation curves and assessment observations to establish a 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. 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 Conveying Systems inventory has previously been entered into BUILDERTM SMS, an inventory is required. When conveying systems are not fully visible (such as chutes), as‐built drawings should be used to identify and quantify the conveying components. If as‐built drawings are not available, the assessor may use experience to make an assumption for the conveying system and quantities based on similar systems, consultation with local staff and other resources such as www.inspectapedia.com.

B. Inventory D1010 Elevators & Lifts Typical inventory at USAF bases includes the following component types:

• Electric Freight EA

• Electric Passenger EA

• Hydraulic Freight EA

• Hydraulic Passenger EA

• Unknown ‐ Accessibility Lifts EA http://www.inspectapedia.com/

5 | P a g e

C. Inventory D1020 Escalators & Moving Walks Escalators or Moving Walks are extremely rare at USAF bases. These would only be found in buildings such as hospitals, exchanges or possibly large administrative buildings, most likely of newer construction.

D. Inventory D1090 Other Conveying Systems Typical inventory at USAF bases includes:

• Automatic or Manual – Dumbwaiter EA

• Linen/Refuse – Chute LF

• Double Beam Crane EA

• Jib Boom EA

• Trolley Hoists EA

Elevators & Lifts D1010 Inventory Hints

• If the building has an elevator, be sure to enter the elevator control room for a thorough assessment. If not able to access, provide an Inspection Comment.

• Record number of stops, usually the same as number of floors. Find nameplate for make, model, serial number and capacity and enter into Section Details.

• If the elevator control room is not accessible, the make and capacity is typically included on the control panel in the cab.

• The annual elevator inspection certificate may be posted in the elevator, on file with the building Point of Contact (Facility Manager) or base Civil Engineering.

The certificate may provide specific information.

• Hydraulic elevators have a large hydraulic oil tank in the elevator control room near the elevator on the lowest floor and will typically be 3 stops or less.

• Electric traction elevators could be more than 4 stops.

• If the elevator capacity information is not available, the assessor should use professional judgment to estimate capacity. Small passenger elevators are typically < 2,500 LBS capacity. Freight elevators are typically > 4,000 LBS capacity.

• Accessibility lifts may be retrofitted on older administrative, recreation or base service buildings.

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

III. Assessment A. General D10 Assessment Guidance

Conveying Component Sections are assessed using Direct Condition Rating (DCR). Usually conveying components will be visible. When Component Sections are not visible, assessment is based on operability or serviceability (work history).

When conveying component sections are visible, they should be assessed. The on‐site assessment is determined using the Direct Condition Rating (DCR) Definitions chart below for major components D1010, D1020 and D1090. The “Rating” reflects observed deterioration, impact on operability, serviceability (work history), and repair requirements based on 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 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 +.”

Note: If no assessment is entered into BUILDERTM SMS, the install date is used as the latest assessment to calculate currency of the equipment. Inventory and an entered assessment of exterior enclosure is mandatory on buildings and other facilities having this system and components and those sections entered without an assessment will be assessment non‐current five years after the installation date.

Under no circumstances should age be factored into a direct or distress survey assessment. Ratings are based on condition, operability and/or serviceability (work history) only. BUILDERTM SMS already factors in the age from the Install Date when BUILDERTM SMS calculates condition.

Elevators and building Weight Handling Equipment (WHE) require an independent inspection/annual

Other Conveying Systems D1090 Inventory Hints

• Do not inventory portable jib‐booms, A‐frames, or lifts added separately after the building was constructed.

• Chutes are quantified by LF. Length can be estimated from floor‐to‐floor height or by reviewing as‐built drawings.

• Chutes and dumbwaiters are uncommon, but may be found in multi‐story barracks or large administrative buildings.

• For lifts/hoists, find nameplate for make, model, serial number, capacity and enter into section details.

• The annual Weight Handling Equipment (WHE)/Crane inspection certificate may be located near the lift controls, on file with the building Facility Manager or Civil Engineering. The certificate may provide specific information.

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

7 | P a g e certification separate from assessments performed under the USAF BUILDERTM SMS program. These certifications are normally performed by assigned base staff or through a service contractor. Prior to performing the BUILDERTM SMS assessment, the assessor should contact the base manager(s) responsible for the annual inspection/certification programs. Assessors should confirm the certification status, and discuss the overall condition of the elevator(s) or WHE included in the BUILDERTM SMS assessment. The assessor should rely heavily on this information to assist in determining the “Rating” in conjunction with the DCR Definitions chart. If available, the assessor may want to obtain elevator inspection reports to assist in determining the rating. Following the BUILDERTM SMS assessment, the assessor should inform the appropriate base elevator program manager of any new issues discovered.

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 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 it is the same assessor who 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 lifecycle 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)

8 | P a g e

Direct Condition Rating (DCR) Definitions

Rating Observation 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

The following conditions or events can accelerate deterioration:

• Improper construction or installation

• Improper maintenance or service

• Improper loading

• Equipment damage

• Coastal or corrosive atmospheric conditions

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

Total operability loss may occur due to some minor reason (e.g. failed switch, hydraulic leak, etc.). In these cases the overall Component Section condition may be “Green” when only a minor repair will correct the problem.

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

9 | P a g e

B. Assessment D1010 Elevators & Lifts

D50 Assessment Hint Questions

• What distresses or problems are observed?

• What is the quantity and severity of the distresses?

• Is the conveying 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 conveying system 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 condition cannot be visually documented, photograph documentation of 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.

Elevators & Lifts D1010 Assessment Hints

• Elevators must have an annual inspection certificate. This certificate should be verified on site or with appropriate staff. If the certificate is out of date, provide an Inspection Comment and notify the appropriate Facility Manager and Civil Engineering maintenance staff immediately.

• Consider information from the building Facility Manager or maintenance staff about the reliability and serviceability of the elevator(s) being assessed.

• Confirm the elevator or lift is on the base preventive maintenance list and maintenance is being performed.

• Ride the elevator or lift to determine if it stops evenly at the appropriate level.

• Accessibility lifts installed outdoors are subject to increased corrosion and moisture damage to the operating system.

• If conveying systems are not visible, an Inspection Comment must be provided.

C. Assessment D1020 Escalators & Moving Walks

D. Assessment D1090 Other Conveying Systems

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

• The assessor should have 5+ years of building construction or maintenance experience related to conveying systems. The assessor should be able to identify common conveying system types/elements and have experience in identifying common problems related to conveying systems.

B. Year Installed

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

• Older buildings may have retro‐fitted elevators. Do not automatically assume the elevator was installed the same year the facility was constructed.

C. Inventory/Assessment

• If as‐builts can be located, they should indicate conveying system type, material, and quantity.

• Conveying systems in large buildings with separate wings or additions should be sectioned separately by elevator number, e.g. ELEV‐1, ELEV‐2, etc.

Escalators & Moving Walks D1020 Assessment Hints

• Similar to D1010

Other Conveying Systems D1090 Assessment Hints

• Similar to D1010

• Do not operate the Weight Handling Equipment (WHE)/Crane to perform the assessment. Coordinate with the building Facility Manager or authorized
