									IT Infrastructure
Quality Control and Cost Savings
Through Commissioning
The Four “I - z”
 (IT)        Investment

 (Design)    Intent

 (Project)   Implementation

 (Final)     Inspection
Design Intent
 Determines the clients goals and objectives
  are met in the design phase
 Establishes the project benchmark
  specifications
 Becomes the baseline for project scope
 Mandates acceptance criteria at the project
  inception
Open Architecture or 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

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
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.”

Building Commissioning Guide:
U.S. General Services Administration
U.S. Department of Energy
July 1998
History of Commissioning
 Origins in HVAC construction

 Accepted practice in the construction process

 Expanded to include other building utilities

 IT Infrastructure Commissioning
      The integrity of the IT infrastructure should be
      evaluated during construction, not after the walls and
      ceilings are complete.
       Why Commissioning ?
 Unclear Designs
 Low Bid contracting
 No established standards for performance
  verification
 Improper needs assessment
 Conflicts between Codes & Standards
 Inadequate documentation
 Need to integrate the new and complex
  building systems
When to Commission
 Life Safety
 Complexity of systems
 Building size and use
 Project type
 Business risk
 O & M (Operations & Maintenance)
  considerations
 Bid process & economic responsibility
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 Commissioning
The intersection of Technology and Facilities

 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
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 savings
 Acts as a “check & balance” for low bid projects
 IT Staff time re-directed core business
 Facility is operational – “the first time”
IT Infrastructure
What It Isn’t?

The IT Infrastructure is not just cable
 and connectors !
IT Infrastructure - What it is
 Are all the necessary physical layer
 components that will effect the
 operational efficiency, network
 performance and reliability of the
 information system.
IT Commissioning Objectives
   Network Connectivity
   Power requirements
   Code compliance
   Installation methods
   Proper space & pathway planning

 Cable Plant Design
 Manufacturer's Warranty
 Certified Installer
 Commissioning Plan
 General Contractor’s Role
