Transcript of Commissioning

Commissioning the process planning design construction turnover operation P R O J E C T T I M E L I N E Each task to be included
Schedule of tasks
Who is responsible for tasks
Lines of communication between team members Basis of Design Document created by the design team
Includes all assumptions, codes, standards, calculations, and design decisions
Describes how design team transformed the OPR into an actual design
Is already accomplished (but not usually provided to the owner) Documenting the Owner's Project Requirements (OPR) OPR is the heart of the commissioning process It is a "living" document (updated as decisions are made)
Provides guidance throughout project for deisgners, contactors and O&M staff
Defines how the owner will measure the success of the project
Simplifies designers' programming or pre-design effort Commissioning Plan Roadmap of how the Commissioning Process is implemented Building Commissioning is a
quality-focused process used to plan, design, build and operate modern, high-performance buildings. Every step was created for a reason: to improve quality in a common problem
Not every project uses every step
LEED requires some steps, gives credits for others, doesn't mention all possible steps “Measure what is measurable, and make measurable what is not so.” Design Review Four Distinct Phases
General Review
Coorddination Review
Discipline Specific Review
Specification Review Key Attributes of a Quality (Commissioning) Process
Must define the end goal
Do it right the first time (more profit)
Each individual is responsible for quality
Verification (not inspection) of work
Focus on the life of the building, not the first day
Improved quality results in lower project costs Develop Commissioning Specifications Submittal Review Site Visits Record Drawing Review Lessons Learned Seasonal Testing Commissioning Report O & M Training O & M Documentation Review Functional Performance Testing Process requirements are included in project specs
Includes techniques to improve submittals, O&M manuals, training and construction quality
Completion of construction, check lists, testing and repercussions of non-compliance should be included
Key milestones Independent review to verify submittals and substitutions meet OPR
Accomplished concurrently with design team and owner review
Input to design team for integration with their comments Workers use checklists to avoid systemic errors
Checklist completion and accuracy randomly verified during site visits by Cx Authority (CxA)
Goal: avoid rework Record documentation regularly verified by CxA
Team meetings held to resolve quality issues and roadblocks
Focus on coordination and achieving the OPR Contractors submit contents earlier (near start of construction)
Avoids last minute effort
Focus is on systems, not just components
Final review by CxA near end of construction
Used as a integral part of the training sessions Presented in small "doses" during construction and turnover
Allows staff time to absorb info and think of questions
Verified/witnessed by CxA
Format is per owner preference, but must be detailed carefully in specifications Galileo Cx writes, instructs the contractor and doucments the results
Verifies the results
Verifies the OPR has been met, systems work seamlessly
Tests all commissioned systems, like envelope, electrical, mechanical
The final report card for entire Cx process
Provides documentation of completion to both owner and contractors G O A L Turnover a building that works! Provides final record of activites completed during the Commsssioning Process
Contains all CX documents (OPR, Basis of Design, checklists, etc.), usually in appendices
Will need to be amended after first year of operation tasks completed Accomplishes any functional testing not done at turnover due to weather (ie. air conditioners)
CxA directs contractors, if contactor assistance is needed, or works with O&M staff
Usually done within 6 months of turnover Warranty Review Accomplished at 10 month point after start of warranties
Joint effort of O&M staff, CxA, and contractors
HINT: Define in specs WHEN warranties must start Uses an independent facilitator (not CxA)
Includes the entire team, from pre-design through occupancy and operations
Workshop format, positive tone
GOAL: Incorporate process improvements on every future project (and learn from mistakes)
