Costs and Benefits
Costs are incurred by the members of theCommissioning team, such as the CxA, owner’srepresentative(s), designer, contractor(s) subcontractors, TAB,major equipment providers, etc.: Items that cost–––––––– are:Report writingMeetings at jobsitesTest instruments, devices, apparatus, protocols, lab tests,Operational, maintenance, and troubleshooting documentationrequirementsConstruction checklists and Functional Performance TestprotocolsFacilitation and supervision of System manual assemblySupervision of Comprehensive training program for operationand maintenance personnel and usersReview of Cx Plan at various phases in the process anddelivering the OPR-Owners Project Requirements (CFR-CurrentFacility Requirements for existing building) and BOD-Basis ofDesign in a format specific for the owner.
Estimated COSTS (2/2) The cost of Cx depends a great deal on the scope of services(systems commissioned) and the area of the country (or world). Does it start at Pre-Design, Design, or Construction? For example: A 100K SF office building could be .02/sq.ft to .25/sq.ft. ( 2K-25K) 100K SF Schools and Institutional buildings range from .25 to .75 / SF. ( 25K-75K) 100K SF Hospitals and labs could be up to .5-1.50/sq.ft.( 50K-150K) ***[Green Building Labeling costs are not included in these costs)]
Why do we use Commissioning? (Summary) Streamlines and improves: The process and work flow Meeting Milestones and Completion Schedules Testing and Verification of Systemsand Assemblies to meet project specifications Training and M&O related activities Warranty “experience” Reduces : Material and labor waste Change orders, delays, punch lists, and claims Risk factors to all parties to reduce their costs Warranty call-backs – disruptions of serviceDelivers a performing building
Benefits of Commissioning Owner:– Improved operator knowledge of how to optimize the facilityoperation and maintenance due to the early inclusion ofoperators in the Cx process– Reduced training requirements due to the continuouslyupdated documentation of how system should operate and bemaintained; personnel will only need to be trained withregard to changes– Facility performance is in accordance with the owner’s projectrequirements– Systems manual provides an easy reference document forsystems and assemblies operation and maintenance– Reduced downtime due to better diagnosis of failures– Improved ability to provide accurate information tocoordinate on facility operation and maintenance– Lower operating costs due to improve operational techniques– Benefits to building occupant including greater productivity,reduced complaints and reduced incidence of absenteeism
Benefits of Commissioning Designer:– Facility will achieve the OPR (Owners ProjectRequirements) or the CFR (Current FacilityRequirements, if existing building)– Reduced risk exposure– Improved knowledge base for use in futuredesigns and installation– Leads to a more cost-effective design– Reduced number of interference drawings duringconstruction due to improved communicationand coordination throughout the project
Benefits of Commissioning Contractor:– Improved planning and coordination through theimplementation of the Cx plan– Improved coordination between different trades– Reduced likelihood of site interference drawingsrequired of contractor throughout the project.– Reduced number of deficiencies at time ofsubstantial completion.– Reduced number of callbacks during warrantyperiod– Reduced number of warranty service calls foroperational guidance, due to participation intraining programs for operation and maintenancepersonnel

Building Commissioning BoomUnder Way, Says Study BOULDER, Colo., 2013:The demand for building commissioning services is acceleratingworldwide, according to a new report by Navigant Research.North America will lead the world in the expandingmarket, accounting for 13.8 billion, or nearly half, ofthe 28.8 billion in total worldwide revenue for buildingcommissioning services during the period from 2012 to2020.Over time, the delivery of commissioning services will be transformedthrough the advent of building energy management systems withcontinuous commissioning capabilities, according to the report.

Commissioning – NEWSFLASHES It is mandatory to commission all LEED projects to a specified level Some states have mandated that state owned or leased buildings becommissioned US FEDERAL GSA has mandated that GSA buildings be commissioned ARMY,NAVY, AIR FORCE and MARINE buildings requirecommissioning More and more hospitals are now requiring commissioning Commissioning is a standard in Canada Required in many European countries, included in Rating systems BRASIL is substantially increasing its commissioning activitiesespecially LEED related Some states have laws that specify “commissioning” does require aprofessional engineer to be in “responsible charge” of the project.

Commissioning BuildsRelationshipsOWNERCOMMISSIONING
What is Commissioning? Commissioning is a serious business andnecessary task Lots of definitions out there The commissioning process is a meansfor achieving, verifying, anddocumenting that the performance offacilities, systems and assemblies meetthe owners and designers definedobjectives and criteria/projectrequirements.
What Commissioning is NOTTesting Adjusting and BalancingInitial Calibration and check-out processPunch listingPre-start-up of systems and troubleshootingContract Administration, Design, orInterpretations Routine Inspections Design or Construction assistance
!!! Commissioning is“All about the Proof” !!!! Talk is cheap Its one thing to make statements that the“systems are installed and operating” . A whole another thing to be willing (and berequired to) to PROVE IT !!Commissioning “measures, documents, andverifies” that the systems and assemblies areinstalled and working.
Common Question ? Should I expect my “Designconsultants or the Contractor” tocommission their own project?Answer: { Big fat NO!!} Commissioning provides 3rd party independentsupervision, monitoring, testing, and verifications.––Building Commissioning is “a quality-focused process for enhancing the delivery of a new andexisting building project.”People are human and can make honest mistakes, forget things, and sometimes things may just gowrong or just not as planned; those are just some of the situations that commissioning can helpwith.

What is ASHRAE Guideline-0-2013 The latest version of Guideline 0 continues todemonstrate the best practices for applying the wholebuilding principles of the commissioning qualityprocess in facility elements. Guideline 0 outlines the process for achieving, validating, anddocumenting the performance of the facility elements inmeeting the defined objectives and criteria of the owner. Thisquality process extends through all phases of the new or majorrenovation projects from predesign to owner occupancy andoperation with tasks during each phase to ensure verification ofdesign, construction, and operator training; meeting the ownersproject requirements (OPR). Guideline 0 describes the overall commissioningprocess in providing a uniform, integrated, andconsistent approach for commissioning facilities.
Purpose: ASHRAE Guideline-0-2013 The Purpose of the guideline is to describethe Commissioning Process capable ofverifying that a facility and its systems meetthe Owners Project Requirements (OPR). [Guideline-0 is for use with new buildingsnote: Guideline 0.2 is for existing buildings]
Scope: ASHRAE Guideline-0-2013 Scope: The procedures, methods, and documentationrequirement in this guideline describe each phase of theproject delivery and the associated commissioning process fromthe predesign through occupancy and operation, without regardto specific elements, assemblies, or systems, and provide thefollowing:– Overview of commissioning process activities– description of each phase processes– requirements for acceptance of each phase documentation of each phase training of O&M personnel These Commissioning Process guideline procedures include theTotal Building Commissioning Process (TBCxP) as defined by theNational Institute of Building Sciences (NIBS) in its CommissioningProcess Guideline 0.
