GSA Commissioning & Recommissioning
What is GSA Commissioning?

GSA has adopted the definition of the
National Conference on Building
Commissioning (NCBC):
“Systematic process of assuring by
verification and documentation, from the
design phase to a minimum of one year
after construction, that all facility systems
perform interactively in accordance with
the design documentation and intent, and
in accordance with the owner’s
operational needs, including preparation
of operation personnel”

What is GSA’s Policy on Commissioning?
PBS DIRECTIVE FOR ASSISTANT REGIONAL
ADMINISTRATORS, PBS DIRECTORS,
PROPERTY DEVELOPMENT DIRECTORS,
PORTFOLIO MANAGEMENT
FROM: F. JOSEPH MORAVEC, COMMISSIONER
SUBJECT: Release of The Building
Commissioning Guide
Summary. Each Prospectus level project team whether on new construction, major repair and
alteration, or modernization -shall use “Total
Building Commissioning” practices beginning with
the project planning phase, and concluding at one
year after tenant occupancy.

GSA Commissioning & Recommissioning
Why Does GSA Commission?




Design Excellence buildings are complex
Our tenants include judges, congresspeople, heads of
federal agencies, and others who we would rather not
disappoint
In all buildings, O&M and utility costs are closely linked to
FFO
In all buildings, tenant labor costs far exceed rent, O&M,
and utilities, so productivity is crucial for tenant satisfaction

Why GSA Total Building Commissions - Really
Sam M Gibbons US Courthouse, Tampa, FL






Built late 1990’s, $ 85 million, 240,000 sq. ft. 17-story, high
rise
2001, building was suspect of having “sick building
syndrome” as employees complained of dizziness,
headaches, and itchy eyes.
The building suffered from significant water intrusion
through multiple facade systems
Extensive investigation of existing facade systems to
document conditions and to identify water infiltration
sources
Design of remedial repairs for multiple types of facade
systems including curtainwall, punch windows, metal
panels, louvers, sealants, roofing systems , davits and
tiebacks for the building
Cost in for repairs and testing $ 20 million
Why GSA Total Building Commissions - Really
Willkie D. Ferguson Jr. Courthouse Miami, FL



Started Construction 2002 with 3-year timeline and $ 100
million budget
Opened 2007 wit $ 69 million increased costs thanks to water
leaks, faulty equipment, and subcontractor lawsuits
Still, after acceptance GSA has had to pay an additional $ 4
million in repairs

GSA Commissioning & Recommissioning
What is GSA Recommissioning?
According to the GSA Building Commissioning Guide,
Recommissioning shall generally include:
• Establishing that original basis of design and operation is still
appropriate for use, occupancy, tenant agencies and GSA
goals, and modify the operations/controls sequencing as
appropriate for optimum operations
• Reviewing and benchmarking key systems
operations/performance against the Basis of Design
• Evaluating envelope tightness/pressurization by infrared or
other methods
• Performing energy analysis
• Recommending repairs/modifications to optimize building
performance
17
GSA Commissioning & Recommissioning
Why Recommission?

Buildings are a moving target

Space usage changes

Equipment changes

Systems change

Original design intent is usually no
longer completely valid
18
GSA Commissioning & Recommissioning
Why Recommission?

O & M is imperfect

Inadequate budgets

Training Incomplete or erroneous
understanding of design intent and how to
run the systems

Incomplete documentation on building

Retrofits, and no single plan of how to run
the systems as modified

Systems are too complex for operators

EISA Sec 432 Evaluation Compliance Plan
EISA Sec 432 requires Federal Agencies complete Evaluations to
include an energy and water evaluations and commissioning
assessment for all of their covered facilities every four years.
Covered Facilities are a subset of an agency’s inventory that
makes up 75% of its total energy consumption.
GSA’s covered facilities are comprised of 198 Facilities across the
11 regions.
