Chapter 17: Commissioning Flashcards
As-built Drawings
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.
BOD
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.).
Cx
Commissioning
CxA
Commissioning Authority or Agent
Commissioning Plan
The document prepared for each project describes all aspects of the commissioning process, including schedules, responsibilities, documentation requirements, and functional performance test requirements.
Commissioning Issues Log
A formal and ongoing record of problems or concerns , as well as associated priorities, implications, and resolutions.
O&M
Operations & Maintenance
What is commissioning?
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.
What is the goal of retro commissioning or recommissioning?
To ensure system operations and performance are in alignment with the operation’s current use or needs.
Who is the commissioning agent?
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.
What is a continuous commissioning?
A systematic commissioning process that continues throughout the project’s lifecycle.
What are the phases of the commissioning process?
- Pre-design (program) Phase
- Design Phase
- Construction & Acceptance Phase
- Occupancy & Operations Phase
What commissioning phase determines the scope of work for the project?
Pre-design (Program) Phase
What types of documents are completed in the design phase?
- Contract documents
- Specification documents
- System documents
During which commissioning phase are maintenance plans developed?
Occupancy & Operations Phase
What are the five levels of testing associated with commissioning?
- Factory testing
- Pre-functional and startup testing
- Component-level testing
- Functional and operational testing
- Whole building (integrated) testing
Give an example of preliminary testing and calibration of a data center’s ESS systems.
- 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
Which type of testing contains the burn-in period?
Preliminary testing
What is Electrical System Functional Testing?
This system-level testing where paralleled or cooperating systems like multiple generators or UPS power modules are tested together as a single unit.
What is Electrical System Operational Testing?
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.
What is the goal of whole building testing?
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.
When is the first session of the system training conducted?
During the acceptance testing to provide initial training needed to operate and maintain the system.
What shall be done after correcting any deficiencies identified by the client?
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.
What shall the testing document include?
Full details of all commissioning tests as well as factory testing reports provided by the manufacturer with the equipment.
What shall be included in the O&M manuals?
- 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
- O&M manufacturer’s manual for installed equipment
- Equipment and systems warranties
- Test templates issues and signed by CxA
- Manufacturer and supplier’s contact data
- Installation drawings As Built
- Equipment list As BUilt
- Diagrams and shop drawings As Built
- Operational sequences
When should the verification of proper system operation and performance be completed?
During the preliminary testing stage to avoid retesting.
This document contains all commissioning tests as well as factory reports provided by the manufacturer with the equipment?
