What is Maintainability?
Facility Maintainability is the practice of integrating
operations and maintenance experience into the
project planning, design and construction process to
achieve ease, accuracy, safety and economy of
maintenance task through the life of the facility.
![Page 3: Checklist for Maintainability - North Carolina...Checklist for Maintainability: An Owner’s Perspective for Design and Construction Jack Colby, Asst. Vice Chancellor for Facilities](https://reader034.fdocuments.net/reader034/viewer/2022042601/5f9fc6b0cfdb8e5556360d43/html5/thumbnails/3.jpg)
What Is Maintainability?
• Durable and long lasting
• Cost effective, TCO
• Flexibility
• Renewable
• Replaceable
• “Bad” experience
produces “Good” results
• Build It As If It Was Your Money. It Is!
![Page 4: Checklist for Maintainability - North Carolina...Checklist for Maintainability: An Owner’s Perspective for Design and Construction Jack Colby, Asst. Vice Chancellor for Facilities](https://reader034.fdocuments.net/reader034/viewer/2022042601/5f9fc6b0cfdb8e5556360d43/html5/thumbnails/4.jpg)
Why Maintainability Matters
• Operations Funding - down 40% over 10
years
• Maintenance staffing = 50% of industry
standards > 75,000 gsf.
• Housekeeping Staffing - >37,000 gsf
• SCO FCAP = DM&CR backlog of $5.4 billion
• Extended Equipment Lifespans
• Low Capital Reinvestment
• State Projects Are Different!

Sustainability
“Development that meets the needs of the present without
compromising the ability of future generations to meet their own needs”
• More Sustainable = More Maintainable
• Proper selections of building material
• Are materials recyclable after use?
• Are the materials locally sourced?
• Are we designing for
disassembly/ replacement
over lifespan?
![Page 6: Checklist for Maintainability - North Carolina...Checklist for Maintainability: An Owner’s Perspective for Design and Construction Jack Colby, Asst. Vice Chancellor for Facilities](https://reader034.fdocuments.net/reader034/viewer/2022042601/5f9fc6b0cfdb8e5556360d43/html5/thumbnails/6.jpg)
Why Sustainability Is Important
• Energy costs continue to
escalate
• 75% of a building’s total
cost is the operating
cost over its lifespan
• State buildings will not
be torn down in 30 years
• Systems will be replaced
3 times during the
building’s life
• Healthy environments

pipe flanges, pipe & duct insulation, I-Beam support
thickness, condensate drains
• Block, Single line, or dimensioned detail
– What is needed to convey the requirement?
– What does the designer need to do to ensure it fits
with adequate access?
DESIGNING FOR MAINTAINABILITY

• Show areas to remain clear on drawings
– Coil pull, items in ceiling, aisles, etc.
• Avoid underground duct and ‘pits’
• ‘Walk through’ (on paper) the Maintenance Tasks
that must be performed – Include operations staff
early in the process
• Discuss how equipment will be replaced
• Detail worst/tightest conditions

Major Takeaways
• Know and Understand the Owner’s Standards
• Ask What the Owner wants; don’t Assume that you know
• Take Life Cycle Cost Decisions seriously -- in all parts of
the design, not just systems
• Design for flexibility of use and renewal over the life of
the building
• Are you designing for access and efficient maintenance?
• Are you training construction trades on expectations?
• What will future maintenance staff say about your
design? Your construction?
