Chapter 17: Commissioning

Question 1

As-built Drawings

Answer 1

Drawing of the facility “as it was built.” Normally, they document any revisions made during construction as a result of change orders, re-locations, re-routing, etc.

Question 2

BOD

Answer 2

Documentation by the design team of the primary thought processes and assumptions behind design decisions that are made to meet the Owner’s Project Requirements. The BOD describes the assumptions used for sizing and selection of systems (i.e. codes, standards, operating conditions, design conditions, weather data, interior environmental criteria, other pertinent design assumptions, etc.).

Question 3

Cx

Answer 3

Commissioning

Question 4

CxA

Answer 4

Commissioning Authority or Agent

Question 5

Commissioning Plan

Answer 5

The document prepared for each project describes all aspects of the commissioning process, including schedules, responsibilities, documentation requirements, and functional performance test requirements.

Question 6

Commissioning Issues Log

Answer 6

A formal and ongoing record of problems or concerns , as well as associated priorities, implications, and resolutions.

Question 7

O&M

Answer 7

Operations & Maintenance

Question 8

What is commissioning?

Answer 8

Commissioning is the process of ensuring systems are designed, installed, functionally tested, and capable of being operated and maintained according to the owner’s design intent and operational needs.

Question 9

What is the goal of retro commissioning or recommissioning?

Answer 9

To ensure system operations and performance are in alignment with the operation’s current use or needs.

Question 10

Who is the commissioning agent?

Answer 10

This is the person or persons with the knowledge, skills, and experience to plan, perform and execute a commissioning plan in one or more of the systems susceptible to commissioning in a building.

Question 11

What is a continuous commissioning?

Answer 11

A systematic commissioning process that continues throughout the project’s lifecycle.

Question 12

What are the phases of the commissioning process?

Answer 12

1. Pre-design (program) Phase
2. Design Phase
3. Construction & Acceptance Phase
4. Occupancy & Operations Phase

Question 13

What commissioning phase determines the scope of work for the project?

Answer 13

Pre-design (Program) Phase

Question 14

What types of documents are completed in the design phase?

Answer 14

• Contract documents
• Specification documents
• System documents

Question 15

During which commissioning phase are maintenance plans developed?

Answer 15

Occupancy & Operations Phase

Question 16

What are the five levels of testing associated with commissioning?

Answer 16

1. Factory testing
2. Pre-functional and startup testing
3. Component-level testing
4. Functional and operational testing
5. Whole building (integrated) testing

Question 17

Give an example of preliminary testing and calibration of a data center’s ESS systems.

Answer 17

• Each access control device for door prop alarms, forced door alarms, and the valid and invalid card reads.
• Each alarm point for intrusion detection and video camera call-up and recording
• Video cameras for resolution, light sensitivity, focus, and where applicable, PTZ control
• The functionality and response of the systems’ graphical user interface (GUI) system
• Intercom and notification systems for proper operation, sound quality, and intelligibility

Question 18

Which type of testing contains the burn-in period?

Answer 18

Preliminary testing

Question 19

What is Electrical System Functional Testing?

Answer 19

This system-level testing where paralleled or cooperating systems like multiple generators or UPS power modules are tested together as a single unit.

Question 20

What is Electrical System Operational Testing?

Answer 20

This phase of testing examines the entire electrical system to verify the interaction of various electrical subsystems and to ensure that the electrical system works as a single, coordinated entity.

Question 21

What is the goal of whole building testing?

Answer 21

The goal of this is to validate that all building utility systems are operating as intended and to verify the proper and expected interactions of those systems and to ensure that they work as a single, coordinated entity.

Question 22

What is the first session of the system training conducted?

Answer 22

During the acceptance testing to provide initial training needed to operate and maintain the system.

Question 23

What shall be done after correcting any deficiencies identified by the client?

Answer 23

The commissioning technician shall correct any deficiencies identified by the client. Upon completion of all corrections, the equipment shall be retested to demonstrate proper operation, integration, and performance.

Question 24

What shall the testing document include?

Answer 24

Full details of all commissioning tests as well as factory testing reports provided by the manufacturer with the equipment.

Question 25

What shall be included in the O&M manuals?

Answer 25

• Contractor
• Table of Contents
• BOD
• Calculation spreadsheet per system As Built
• CD As Built
• Material spec
• Approved submittals
• Incident registration
• O&M Procedures
• Maintenance schedules
