Commissioning
“the process of ensuring that the systems are
designed, installed, functionally tested and
capable of being operated and maintained to
perform in conformity with the design intent.
Commissioning begins with planning and
includes design, start-up, acceptance and
training and can applied throughout the life of
the building.”
ASHRAE – Guidelines 1996
Commissa 2003
Commissioning
“building commissioning” is the process for
achieving, verifying and documenting that
the performance of the building and its
systems meet the design intent and the
owner and occupant needs.”

History of Commissioning
Origins in HVAC construction
Accepted practice in the construction process
Expanded to include other building utilities
Third party verification
Entire building commissioning
Commissa 2003
Why Commissioning ?
Unclear Designs
Low Bid contracting
– Quality Control
No established standards for
performance verification
Improper needs assessment
Conflicts between Codes & Standards
Commissa 2003
Why Commissioning ?
Inadequate documentation
Need to integrate the new and complex
building systems
Convergence
Reliability and Redundancy critical to
single IP networks
Commissa 2003
Why Commissioning ?
“The
design and integrity of the
IT infrastructure should be
evaluated during entire building
process. From initial design,
through the construction
process and including network
validation- not after the walls and
ceilings are complete”
Commissa 2003
When to Commission
Life Safety
Complexity of systems
Building size and use
Project type
Business risk - Mission Critical Facilities
O & M (Operations & Maintenance)
considerations
Bid process & economic responsibility
Public Sector funding
Commissa 2003
Design Intent
Determines the clients
goals and objectives are
met in the design phase
Establishes benchmark
and specifications
Becomes the baseline for
project scope
Mandates acceptance
criteria at the project
inception
Commissa 2003
Economics of Commissioning
Cost Saving range from 5-10% by
eliminating design related change orders
Deficiencies are identified and remedied
before completion when it is more
economical
Funding commissioning as part of the
project represents a 2-5% of project cost.

IT Infrastructure
What It Isn’t?
The IT Infrastructure is not just
cable and connectors !
Commissa 2003
IT Infrastructure - What it is
…all the necessary physical layer
components that will effect the
operational efficiency, network
performance and reliability of the
information system.
Commissa 2003
Open Architecture vs.
Proprietary Systems
Open Architecture
– Interoperability required by TIA 568B.1
– Lower cost
– Pick and choose products
Proprietary Systems
–
–
–
–
Matched and balanced for maximum performance
Warranties available
Limited product selection
Requires systems training

The intersection of
Technology and Facilities
IT Infrastructure Commissioning
Commissa 2003
IT Infrastructure Commissioning
Application of established commissioning
procedures to IT Infrastructure
requirements
Combination of IT expertise and
construction experience
Bridges the gap between IT needs and
architectural specifications
Ensures the reliability of the new
converged technologies (IP)
Commissa 2003
Benefits of IT Commissioning
Identifies the owners requirements in
accordance with the design intent
Cost savings by reducing change orders
due to errors and omissions
Quality Control Process
Acts as a “check & balance” for low bid
projects
IT Staff time re-directed to core business
Facility is operational – “the first time”

Case Study Conclusions
Specifications were minimally enforced
Marginal workmanship issues were
resolved by the warranty and
commissioning
IT inspection reports were
overwhelming
Commission Report identified additional
deficiencies and subsequent corrective
action.
Commissioning ROI was Five to One
