What is the primary objective of conducting pre-demolition readings in TAB?
(Required)
Estimate demolition duration
Verify energy usage trends
Schedule commissioning
Establish system performance benchmarks
Locate hazardous materials
Which parameter must be validated for VAV systems during pre-demolition assessments?
(Required)
Room temperature setpoint
Date of last calibration
Downstream duct static pressure control setpoint
Space relative humidity
Duct insulation thickness
When dealing with legacy hydronic systems, which precaution is technically recommended?
(Required)
Anticipate valve corrosion and prepare for leakage containment
Bypass flow measurement ports
Assume standard flow conditions
Utilize infrared thermography exclusively
Open all isolation and balancing valves for faster testing
What common obstacle affects water-side flow measurement accuracy in older systems?
(Required)
High sunlight exposure
Overinsulated piping
Clogged or non-existent flow measurement ports
Water Hammer
Inverter harmonics
Why are pre-demolition readings often underutilized in field practices?
(Required)
Technicians lack proper equipment
They are misclassified as routine checklist tasks
Too many external vendors involved
They duplicate final TAB reports
They cause schedule delays
Effective communication with the Cx agent and design engineer ensures:
(Required)
Increased project billing
Clear delineation of maintenance roles
Proper interpretation of system performance anomalies
Minimizing LEED documentation
Automated system control tuning
Which tool is LEAST essential for verifying HVAC system operation during pre-demo testing?
(Required)
Tachometer
Manometer
Flow hood
Amp Probe
Pipe threading tool
‘Keeping the end in mind’ means TAB technicians should:
(Required)
Assess whether retained components can meet future design criteria
Confirm data aligns with demolition timelines
Complete readings as quickly as possible
Ensure access panels are reinstalled
Check warranty compliance on all components
How should technicians respond to inaccessible or non-functioning test ports?
(Required)
Continue testing at alternate sites without documentation
Notify controls contractor only
Document all inaccessibility and measurement failures in the report
Assume values based on similar zones
Use estimated data in calculations
Creating a feedback loop between TAB and engineering teams helps:
(Required)
Reduces Scope of Work
Skip rebalancing post-renovation
Eliminate static pressure control
Reduce sensor calibration needs
Align existing conditions with future system design assumptions
