A. B10 Superstructure Description

1. UNIFORMAT definition

• Facilities superstructures are above ground and overhead structural components supporting other facilities systems such as the exterior enclosure, roofing and interior construction or supporting equipment. Also includes components for towers, aircraft sun shade structure, overhead canopies, observation towers, and permanently installed covered and uncovered reviewing stands.

2. Major components

• Floor Construction (B1010) – Includes balconies, ramps, columns/pillars, elevated floors, beams/girders, joists and slabs at intermediate floors.

• Roof Construction (B1020) – Includes awnings, beams/girders, joist, rafters, trusses, purlins and decking supporting the roof coverings and roof top equipment. As best choice system choice, various tower structures and other metal structures have structure inventoried here.

3. Lifecycle characteristics

• Most Superstructure components are classified as longer lived or very long‐lived components. Most Superstructure components show slow rates of deterioration, but are more subject to damage and deterioration than foundation elements. A few elements such as canvas/vinyl tubular metal or wood structure awnings are short‐lived components.

II. Inventory A. General B10 Inventory Guidance

This section presents common UNIFORMAT II B10 Superstructure 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 with Material Category, Component Subtype, Quantity and Inventory Notes. Each facility’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 in the Documents Library. Section VI (B10 UNIFORMAT II Minimum Component Reference Table) provides a

4 | P a g e complete listing of the minimum components inventoried and assessed for B10 for the USAF. Bases may elect to inventory and assess additional components.

NOTE For the B10 system: Only Missile Alert Facility (MAF) Missile Operations Buildings (MOBs), Launch Facility (LF) Launch Support Building (usually referred to as Electric Power Station Building) underground structures and Munitions Storage facilities are routinely required to be inventoried and assessed in BUILDERTM SMS. Inventory and assessment for tower type structures generally supporting communications equipment, observation towers, aircraft sun shelters, permanently installed reviewing stands, and overhead protection canopies is required. For Hangar and Warehouse facilities, inventorying and assessing superstructure is recommended where visible. Bases may elect to inventory and assess superstructure components for other facility types. B10 Inventory and assessment is required by the current AFCAMP Playbook (Business Rules) as project support documentation for consideration in the project prioritization process for all components included in the project Statement of Work.

Component subtypes General, Other, and Unknown require a Section Name and Inventory Comments, if required, to identify further identify and describe 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/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 Superstructure inventory has previously been entered into BUILDERTM SMS, an inventory is required. When Superstructures are not visible, as‐built drawings should be used to identify and quantify the Superstructure components. If as‐built drawings are not available, the assessor may use experience to make an assumption for the Superstructure types and quantities based on similar construction of nearby buildings, consultation with local staff and other resources such as www.inspectapedia.com.

The remainder of this section provides photo examples of the most common USAF inventory items categorized by major components and accompanied with appropriate Material Category, Component Subtype and unit of measure 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.

III. Assessment A. General B10 Assessment Guidance

Superstructure component sections are assessed using Direct Condition Rating (DCR). Much of the time Superstructure component sections are not visible. When Component Sections are not visible, assessment is based on serviceability (work history).

When superstructure component sections are visible, they should be assessed.

Note: If no assessment is entered into BUILDERTM SMS, the install date is the initial assessment is considered as the latest assessment and assessment currency is calculated from this date. Currently, System B10 is not considered in the determination of assessment currency for any respective facility except tower type structures generally supporting communications equipment, jet blast deflectors, observation towers, aircraft sun shelters, permanently installed reviewing stands, overhead protection canopies, etc.

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 factors in the age from the Install Date when BUILDERTM calculates Condition Index (CI).

The following conditions or events can accelerate deterioration:

• Improper construction or installation

• Settlement or subsidence

• Material damage

• Flooding

• Earthquake

• Landslide

• Soil erosion

• Moisture infiltration

The assessor may observe distresses in the visible Superstructure major components such as cracking, displacement, rotting or other damage. These conditions may also be visible in interior or exterior walls and the floor. In these cases the assessor shall evaluate the impact of observations and use judgment to provide a DCR using the DCR chart below.

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 it is 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.

DIRECT CONDITION RATING MATRIX

NOTE: Red highlighted text below is provided as an example of a lifecycle of a 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 or replacement can be planned if good return on investment; within the FYDP. (Investment of resources could extend life)

Amber Reduced Operation – Moderate wear and/or serviceability defects Repairs or replacement can be planned if good return on investment; within the FYDP (Investment of resources could extend life).

Amber (‐) Reduced Operation – Significant wear and/or serviceability defects Repairs or replacement can be planned if good return on investment; within the FYDP (Investment of resources could extend life).

Red (+) Loss of Operation – Moderate wear and/or serviceability failure Repairs or replacement must be planned within the short term (High risk to Mission ‐Run to failure ‐further investment unwise)

Red Repairs or replacement must be planned within one year (High risk to Mission ‐ Run to failure ‐further investment unwise)

Direct Condition Rating (DCR) Definitions

Rating Observation Red (‐) Loss of Operation – Complete wear and/or serviceability failure

Repair or Replacement needs to be planned immediately

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

B. Assessment B1010 Floor Construction

Some Floor Construction may not be visible in buildings with floor covering or finished ceilings (elevated slabs). N o assessment will be entered under these conditions unless the assessor observes some portion of the Roof Construction, observes distresses noted above, or has access to an engineering report allowing BUILDERTM SMS to Age‐Base the Rating.

B10 Assessment Hint Questions

• What distresses or problems are observed?

• What is the quantity and severity of the distresses?

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

Based on above:

• 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 rating if a significant localized issue needs to be highlighted which may not necessarily impact the overall component section DCR.

• If superstructure components are not visible, an Inspection Comment must be provided.

Examples of typical floor construction distresses or conditions include: rot, structural damage or displacement.

C. Assessment B1020 Roof Construction Roof Construction will normally not be visible unless the building is a warehouse or maintenance type structure with no finished ceilings. N o assessment will normally be entered unless the assessor observes some portion of the roof construction, observes distresses noted above or has access to an engineering report allowing BUILDERTM SMS to Age‐Base the Rating.

Examples of typical roof construction distresses or conditions include rot, structural damage or displacement.

1. Roof Supporting Members with Water Damage.

IV. Inventory and Assessment Rules of Thumb

A. Assessor Qualifications

• The architectural/structural assessor should have a combination of 8+ years of general building construction, facilities maintenance and planning/estimating experience related to building foundations, structure, enclosure and interior construction or be equivalent to a Journeyman, a V Level Technician, an Architect or a Civil Engineer. The assessor should have a working knowledge of the ASTM E 1557 Standard Classification for Building Elements UNIFORMAT II and a basic understanding of other building systems such as HVAC, Plumbing, Fire Protection and Electrical. The assessor should be able to identify common building materials, techniques and structural/architectural system types/elements, be proficient at reading drawings and engineering reports and have experience identifying common problems related to architectural/structural systems. The lead architectural/structural assessor may be supported by less experienced staff during the inventory and assessment.

B. Year Installed

• In some cases superstructure 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 superstructure age must be estimated. The building occupants or other facilities staff may be able to provide some information.

• If construction drawings or as‐builts are available, look for date published to assist with determining age of materials.

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

• In the case of superstructures, the assessor must use judgment in sectioning these components. Superstructure components should be sectioned in the manner they are generally managed. If there are no new superstructures, a separate section for a single new superstructure is not necessary. However, if there are two major types or ages of superstructures, then separate sectioning is a good idea.

C. Inventory/Assessment

• If as‐built drawings can be located, they should indicate superstructure type, material and quantity.

V. Inventory / Assessment Data Collection Sheet Construction drawings, floor plans, or digital device are commonly used. Use whatever collection method works best for the individual assessor/organization.

VI. B10 UNIFORMAT II 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. Usually, components are assessed with Direct Condition Ratings. As appropriate, 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 reflects the AMP to which the component is assigned:
