ABOUT THIS GUIDELINE The purpose of this guideline is to set out the commissioning process for new buildings, systems and equipment installed by IO’s Project Management Service Providers (PMSP) and Property and Land Management Services Providers (PLMSP) operating under the Master Services Agreement between IO and each PMSP and PLMSP. The guideline describes the minimum requirements and limitations of the required commissioning services for projects delivered by PMSPs or PLMPS through the planning, execution and close out phases of the work. It is bound by the relevant articles in the MSA, which requires the PMSP to provide acceptable and appropriate commissioning of operating systems and equipment as a part of the services. The intent of this guideline is to ensure building equipment performs as specified and originally intended as per IO Design Guidelines, installation of equipment meets contract specifications, the commissioning of building systems/equipment, sequence of operations have been verified to on site conditions, and the total performance/integration of new equipment/systems are fully commissioned. Studies must identify existing building conditions and identify available options based on performance, efficient operation, operating, and capital costs. The options identified in the study shall include Life Cycle Cost Analysis, payback, implementation and preventive maintenance costs, energy savings, and return on investment up to a 25 year period, with a full integration with this guide. Design solutions are to be based on the studies and confirmed by the Design Engineer. The design engineer is responsible for the overall design and performance and integration of building systems to ensure that they are specified, installed, commissioned and equipment is operating within their design intent, with a full integration with this guide. Building systems installations are to ensure that the contractor has supplied and installed the equipment and is operating as originally specified and intended to operate. The contractor and consultant are to ensure that final sequence of operations are completed and adjusted throughout the commissioning and warranty process as required. References are made to ASHRAE Commissioning Guideline 0 in various sections, but IO Commissioning Guideline does not reiterate those procedures that are very familiar to the design and construction industry. It is more heavily focused on the initiation and outcomes of commissioning specific to IO’s projects, than the commissioning process. Any definitions that differ from ASHRAE definitions are acknowledged. In this guideline, the traditional ASHRAE term “Owner” is sometimes represented by the term “stakeholder”. Projects undertaken by PMSP will have multiple stakeholders each of who have specific “owner” interests to be verified through the commissioning process. These are: • • • IO Asset Management who are responsible for the building operation and meeting performance targets, particularly in the area of system reliability, energy efficiency and sustainability; IO’s PLMSP currently “CBRE Limited”, who operate most IO facilities across the Province, and are contractually bound by fee at risk performance measures; and IO’s Customer Ministries who demand efficient and comfortable buildings from which to operate their specific programs, some of which involve their own specialized equipment and systems. INFRASTRUCTURE ONTARIO – 2015 Building Systems Commissioning Guideline 4 2. DEFINITION This guideline uses definitions included in ASHRAE Commissioning Guideline 0, the PMSP MSA, the IO Design Guideline, the IO Sustainability Standards, and other IO contractual documents. Additional information regarding the Project Delivery processes described below is found in the Asset Management Project Delivery Methodology matrices and process maps. Asset Management: IO’s business unit responsible for management of the portfolio of government owned and leased properties through the services of the PLMSP. Asset Management also oversees project delivery undertaken by the Project Management Service Provider(s). Building Systems: The dynamic operating systems in a building that will be subject to the commissioning process, including but not limited to: HVAC, automation, refrigeration, plumbing, power and lighting, life safety, fire protection, vertical transportation, site services, communication and signal, audio visual, security, food preparation and storage, and other specialized systems. In this guideline, Building Systems includes specialized equipment or systems included in the construction that may be provided for customer programs, such as security systems, CCTV, uninterruptible power supplies and computer room cooling systems. The building envelope including roofing assembly (while not a dynamic system) is also considered a building system for the purposes of this guideline. Checklists: Verification checklists that are developed and used during all phases of the commissioning process to verify that the owners project requirements are being achieved. This includes checklists for general verification, plus testing, training and other specific requirements. CMMS (Computerized Maintenance Management System) Inventory Forms: a tabular process to record specific data on every piece of building equipment that is added, changed, removed or replaced within the scope of the project, to be included in the project O&M manuals, and deliver to the PLMSP CMMS database for inventory and lifecycle maintenance management. Commissioning (Process): a quality assurance oriented process that ensures the building systems and assemblies perform interactively according to the design document, and that the stakeholders’ objectives and operational criteria are achieved through a process of planning, testing, verifying, and documenting the performance of the facilities as it is constructed, and where necessary through seasonal commissioning after occupancy. Commissioning Authority: an individual or firm identified by the PMSP who will lead, plan, and schedule and coordinate the activities to implement the commissioning process. The commissioning authority may be the project design consultants for lower complexity projects, or another specialist retained by the PMSP. This definition reflects IO’s model and may be slightly at variance from the ASHRAE definition. See also: Independent Commissioning Authority. Commissioning Plan: a document prepared by the commissioning authority to set out the organization, schedule, and allocation of resources, specifications, and documentation requirements of the Commissioning Process Commissioning Reports: functional performance verification reports, test data records, performance reports etc that record the commissioning results for every item of equipment, assembly, or entire system as described in the commissioning plan. Commissioning Verification Forms: an IO template to record the completion of commissioning work that is documented in detail in the commissioning reports Commissioning Issues Log: a formal and ongoing record of problems or concerns, and their resolutions, during the course of the Commissioning Process, and included in the Final Commissioning Report. Contractor commissioning: commissioning activities on non-complex projects carried out by the contractor following a basic commissioning plan, but not necessarily needing a commissioning authority. Design Review - Commissioning: a review of the design documents to determine compliance with the Owner’s Project Requirements, including coordination between systems and assemblies being commissioned, features and access for testing, commissioning and maintenance, and other reviews required by the commissioning plan. Independent Commissioning Authority: a commissioning specialist who is independent of the design team engaged by the PMSP who leads, plans, and schedules and coordinates the commissioning team to implement the INFRASTRUCTURE ONTARIO – 2015 Building Systems Commissioning Guideline 5 commissioning process for complex or LEED projects. This term “independent” reflects IO’s model and may be slightly at variance from the ASHRAE definition. Ministry Scope Definition Document: a checklist used by the Ministry to identify in scope requirements of a project. It is submitted as an attachment to the Project Services Initiation form. Operations and Maintenance (O&M) Manual “Schedule B”: systems-focused composite document of use to the building operator and owner during the occupancy and operation phase, which includes the owner’s requirements, operating manual, maintenance manual and additional information such as warranties. Each O&M manual shall include an electronic copy in searchable PDF format of the manual on a CD or DVD in the back of the manual. Owner: the various project stakeholders, being IO, its PLMS, and its customer ministries, each of which may have program specific requirements and deliverables that may vary between building types and regions. Owner’s Project Requirements (OPR): The IO Design Guideline, a document that details functional requirements for the project and the expectations of how it will be used and operated. Post Occupancy Commissioning: the detailed calibration of the systems and equipment designed to control the indoor environment, through a full cycle of four seasons (usually 12 months or longer, commencing from the date of Substantial Performance), to maximize the building efficiency and occupant comfort. Project Bid Documents: a collection of written documents including bid information and forms, contract forms and conditions, and drawings, specifications and schedules, the combination of which provides all particulars required to complete the construction project, including commissioning specifications for each trade. Project Charter: the IO form used to confirm the client/stakeholders’ scope, schedule, budget and other delivery considerations in the initiation stage of a project or study Project Management Service Providers (PMSP): an entity engaged by IO to provide all services required to deliver projects in accordance with the MSA. In this Guideline the term “PMSP” means any employee of the PMSP team. Project Justification Form (PJF): a form prepared by IO, or its PLMSP to identify scope and funding requirements related to upcoming capital repairs and replacements. Project Services Initiation Form (PSIF): the form prepared by customer ministries to authorize funding and request initiation of a customer funded project. Project Service Manager (PSM): the IO project manager (IO Representative) who oversees the PMSP’s activities at a regional level, to ensure delivery of projects to meet owner’s needs. Project Delivery Methodology: the business process designed in accordance with PMI principles that prescribe each discrete element and sub element for delivery of a design and construction or study project to be delivered by PMSPs. The elements are organized in phases described as “Initiation, Planning, Execution and Close Out”. Property and Land Management Service Provider (PLMSP): a third party firm retained under a long term contract to manage and operate IO properties on IO’s behalf across the province. Startup Checklist: the record of the initial starting or activating of systems and equipment, including completion of construction checklists. Scope of Work: means the description of the project scope as approved by the client through the project charter. Training Plan: a written document that details the expectations, schedules, budget and deliverables of commissioning process activities, related to training of project operating and maintenance personnel, users and occupants. Verification: the process by which specific components, equipment, assemblies, systems, and interfaces among systems are confirmed to comply with the criteria described in the Bid documents and the project requirements. INFRASTRUCTURE ONTARIO – 2015 Building Systems Commissioning Guideline 6 3. INTRODUCTION 3.1 PREAMBLE Traditionally, the term “commissioning” generally means testing and acceptance of only individual components and systems of newly constructed facilities such as the HVAC systems, elevators, electrical and life safety systems. Today, with increasing concerns of meeting energy targets, emphasis on the green environment, increased complexity of building systems, equipment, assemblies, new materials, and the impact on the environment and sustainability, there is a renewed emphasis on commissioning as an important part of ensuring sustainability targets are met in new construction, and also through the operating life cycle of our buildings. In this context, commissioning will sometimes extend to static elements of buildings such as building envelope (doors, windows, and cladding and roof systems) which are a key part of overall building performance. IO has many commitments to sustainability established through assessment and target exercises, and companywide targets. In 2008, IO established sustainability objectives that are now embedded in its corporate goals, including reducing electrical demand, increasing waste diversion, extended certification of buildings, and responding to a sustainability framework. In 2007, the Government adopted the LEED framework as the standard for all new Ontario Government buildings that meet established criteria. Commissioning by a third party is a mandatory component of LEED certification. The Government is expected to direct (within parameters described later), that new buildings and major building retrofits will be designed to achieve LEED silver as a base level certification. Within the certification, there will be mandatory LEED credits related to re-commissioning procedures to maintain the LEED levels of operational performance throughout the lifecycle of the building. IO projects delivered by PMSPs by nature are “situational”, meaning that the commissioning requirements for each project will vary according to the project scope, cost, complexity, and various other project specific factors. For this reason these guidelines are scalable for various project sizes and types, and can be adjusted at the project charter stages by default and exception mechanisms, as mentioned in the IO Design Guideline. 3.2 SCOPE The intended audience for this guideline includes: • • • • • Ministry and IO Program Planners Property Land Management Service Provider (PLMSP) Project Management Service Providers (PMSPs) Commissioning Authorities, Consultants and Contractors (if no Consultant engagement), and Project Services Managers (PSMs) Supplementary technical guidelines for any given system or assembly are not included, but may be developed later by IO if required to provide specific information on specialized systems. When using this guideline, the user should always check the PMO Web portal to ensure they have the most current version. This guideline is organized around the project management principles established by the Project Management Institute (PMI), being the framework for the business processes in the Project Services business model, and embedded in the articles of the Master Services Agreement. It includes principles from the ASHRAE Commissioning Guideline 0 “The Commissioning Process”, and the terms and actions described herein are consistent with the requirements of the Construction Lien Act (Ontario), OAA Document 600, and Document 100 (OAA/OGCA Take over Procedures). This guideline describes the application of the Commissioning process for the entire project life cycle beginning with project identification in the Program Planning phase followed by the Initiation, Planning, Execution, and Close Out phases as summarized below: • • Program Planning and Project Identification Phase identifies the Owner’s Project Requirements and commissioning requirements including the identification of specific CMMS forms. Initiation Phase describes the intended commissioning process as established by IO in the project charter. INFRASTRUCTURE ONTARIO – 2015 Building Systems Commissioning Guideline 7 • • • 3.3 Planning Phase The Commissioning Authority sets out the commissioning requirements, including the equipment specific CMMS forms for existing equipment to be modified and/or removed, during the project design work. Execution Phase describes the requirements for start-up, verification, performance testing, and training during the construction stage, including post-occupancy Seasonal Fine Tuning and final submission of CMMS forms for new equipment. Close Out phase describes the handover documents and requirements for post occupancy commissioning at the close out stage of the project, and re commissioning where it applies. APPLICATION The unique nature of any project (or program of similar projects) means that each project will require its own documentation, performance criteria, and checklists for each system or assembly to be commissioned. Throughout, references to process thresholds, codes, other guidelines and industry references should be considered as the minimum, whereas the project stakeholders have more stringent requirements, Owner Project Requirements that may modify or replace the benchmark for verifying the requirement. This includes hiring an independent commissioning authority as per schedule A & C or if requested by IO or its representatives. 3.4 GOVERNANCE Ministry Accommodation Planners and PLMS Facility Managers are responsible for project identification and ensuring commissioning requirements comply with this guideline. IO Staff (General Managers, Portfolio Performance Manager and Project Services Managers) is responsible for an initial definition of the commissioning deliverables in the project charter. Also, to review and approve a project charter, approve an acceptable Commissioning Plan, and oversee PMSP compliance with the approved commissioning activities The PMSP is responsible to refine and confirm the commissioning requirements in the project charter, including all associated costs. The PMSP is responsible for preparation of a commissioning plan (via the design consultant or commissioning authority) to define the contractor’s activities, implementation of the plan by the Contractor, including post occupancy commissioning if any, and reporting of commissioning performance at Close Out, in accordance with the plan. INFRASTRUCTURE ONTARIO – 2015 Building Systems Commissioning Guideline 8 4. INITIATION PHASE 4.1 OBJECTIVE The objective in this phase is to ensure that planning for commissioning proceeds in an organized manner as per this guideline to ensure the project charter is complete and accurate, and to avoid project charter changes after approval. A properly defined project charter is the cornerstone of an effective commissioning program. 4.2 PROJECT INITIATION In the project delivery methodology, the Initiation Phase includes all processes beginning with a request to initiate a project through a PSIF or a PJF, to where a consultant is retained by the PMSP to begin design. A key step in this phase is that the PMSP identify and confirm commissioning requirements in the project charter. Preparation of the project charter includes a detailed project scope of work including requirements in the PSIF/PJF and any attachments to those documents. Within the project scope, the intended Commissioning approach (in respect to the specifics of the project) should be defined. Section 3 of the project charter also includes a simple check-box section to indicate (among other things) commissioning related deliverables and project specific requirements such as the need for an independent commissioning authority. 4.3 IO RESPONSIBILITIES Project Charter: The PSM must ensure that IO Design Guideline and IO commissioning Guideline requirements are included in the Project Charter produced by the PMSP. 4.4 PMSP RESPONSIBILITIES: At project initiation the PMSP will determine the following parameters and enter the details in the project charter. The PMSP will make any enquiries necessary to clarify the intended scope of work to determine the basic commissioning requirements: • • • • • Is commissioning needed in this project? For most building systems, Answer should be yes. If no, provide a reason why it is not needed? If yes, provide a high level description of the scope of commissioning required including a list of which systems will be commissioned. Is this a “LEED” certified project, and what level of certification will be pursued? Is this an energy savings driven project which requires measurement and verification? Based on the anticipated schedule and system complexity, is the post occupancy commissioning needed? The PMSP will also select and indicate the required deliverables, and the project specific requirements related to commissioning in Section 3 of the project charter. Commissioning Thresholds: Refer to Schedule A Commissioning requirements for IO projects delivered by PMSPs need to be scalable to match a wide range of project types, scope, cost and complexity. Schedule A of this Guideline provides a chart of thresholds to be used to determine who will oversee the contractor’s commissioning activities. The IO Design Guideline provides the Owner Project Requirements. The decision on who will manage the commissioning, guided by schedule A, will be confirmed by all parties in the project. It is essential that the PMSP fully understand the scope of work, in particular the work to be performed on building systems, to be able to define the high level commissioning requirements ensuring that The IO Design Guideline is followed. In Capital and Repair projects, the PJF will usually be accompanied by substantive technical information that should permit the commissioning decisions to be made with minimal additional effort. Conversely, in ministry INFRASTRUCTURE ONTARIO – 2015 Building Systems Commissioning Guideline 9 funded projects, the information may be no more than what is included in the PSIF, which will require some investigative work by the PMSP to complete the commissioning requirements in the project charter. Project Specific Requirements must follow the sections below • • • • Owner’s Project Requirements (OPR) – IO Design Guideline Commissioning Authority – see Schedule A & C M&V Consultant – measurement and verification role, key in energy savings projects, Post Occupancy Commissioning – consider project timing, system complexity and seasonal impact on system operation such as HVAC Complete the Project Charter Once the level of commission is determined and client agreement is reached, the associated costs for commissioning must be included in the project estimate. This is a critical step because once all parties have signed off on the project charter a subsequent change will require a charter change process. INFRASTRUCTURE ONTARIO – 2015 Building Systems Commissioning Guideline 10 5. PLANNING PHASE 5.1 OBJECTIVE The objective of the activities in this phase is to clearly lay out all commissioning activities in a complete and logical manner, ensuring a successful outcome to the commissioning activities to follow in the execution phase. 5.2 THE COMMISSIONING PLAN Schedule A describes 3 thresholds of commissioning responsibilities: • • • Projects where NO Design Consultant is engaged, contractor and trades are responsible for all commissioning activities (contractor commissioning) Projects up to $1million where the Design Consultants are the commissioning authority, as long as certified. Projects over $1million where the commissioning authority is a specialist that is independent of the design consultants and the PMSP. The designer and/or commissioning authority will prepare an initial commissioning plan (the plan) near the completion of schematic design stage. The plan will prescribe all activities and responsibilities to be completed throughout the subsequent planning, execution and close out stages. The PSM, Asset Management staff, PLMSP and the ministry representative will review the plan and provide comments to the PMSP. As the project proceeds through the design stages the plan will be updated to reflect the specifics of the project. The plan will be finalized at the completion of the bid documents stage and will be included in the bid document package to be reviewed by IO Asset Management, PLMSP and the ministry representative where appropriate. Once all comments have been addressed by the designer and/or commissioning authority, the PMSP will formally accept the plan. The initial investment of time in a properly developed plan will be repaid later in the project as it will form the core of the final commissioning report. The plan should be based upon ASHRAE Commissioning Guideline 0, and at a minimum, should include the following topics: • • • • • • • • • • • • • Overview of the commissioning process specific to the project including definitive listing of systems to be commissioned Format for describing commissioning requirements in trade sections of the specifications Startup checklist sample as provided by recognized equipment manufacturer representative(s) Intended test procedures, and test data records specific to the project Statement of design and performance requirements Detailed description of activities during the construction, substantial performance, occupancy and post occupancy stages Format for commissioning submittals and final documentation for verification, and performance testing CMMS verification forms and data collection process Review of shop drawing submittals for compliance with design intent Procedures for situations where verification process fails to achieve design requirements Quality based sampling procedures for verification of design requirements having been achieved Issues log process, and corrective procedure Procedures specific to LEED certification where applicable INFRASTRUCTURE ONTARIO – 2015 Building Systems Commissioning Guideline 11 5.3 OPERATION AND MAINTENANCE MANUAL In accordance with the MSA, the PMSP will coordinate the development of an Operations and Maintenance Manual, Schedule B of this guide. The O&M manual will be submitted in hard copy and electronic copy versions, meaning every part of the manual must be scanned into an electronic form. The manual will be prepared by the general contractor, certified by the design team as well as the commissioning authority, and once accepted by the PMSP, submitted to the client and IO at Substantial Performance. The requirement for an O&M manual will be noted by PSM in the project charter. The manual may take several forms: • Where the project involves significant work on building systems and the project will produce information essential to the ongoing operation of the building such as commissioning data, equipment inventories, warranties, maintenance data etc, a full scope O&M manual is required; • Where the project involves minor change to building systems and the quantity of project information related to the ongoing operation of the facility is minor, a condensed version of the O&M manual is required. This reduced scale manual could be considered as an annex to the existing O&M manuals for the facility. On a project specific basis, where little significant documentation will be produced to pass on to IO, the PSM may determine that an O&M manual or an annex to the manual is not required, and shall indicate that in Section 3 of the project charter. 5.4 COMMISSIONING AUTHORITY TASK AT THE DESIGN STAGE In projects where the project design team will be the commissioning authority, IO will rely upon the professional integrity of the entire design team under the direction of the PMSP, to achieve the design intent through all design stages, in the most cost effective and environmentally responsible manner possible in compliance with this guideline. In projects where an independent commissioning authority will be engaged, they must be hired sufficiently early in the planning phase to ensure the Owner Project Requirements are translated accurately. They will formally review the design as it evolves, confirming that it will achieve the owners’ project requirements, and that the systems are arranged to permit commissioning to be implemented effectively. 5.5 BID DOCUMENTS AND COMMISSIONING PROCESS A critical subset to the commissioning plan is the documentation of the commissioning process for each trade section in the specifications portion of the bid documents. When the commissioning requirements are clearly defined in the bid documents under the relevant specification division, the contractor is contractually bound to the process, and bidders are fully informed at the tender stage. The PMSP will ensure that the format for commissioning specifications set out in the commissioning plan is accurately translated by the design team into the bid documents. 5.6 CMMS INVENTORY PROCESS The Computerized Maintenance Management System (CMMS) is a database operated by the PLMSP that records all life cycle data logged against an item of equipment or system. This is an important feature as it permits the PLMSP to determine service and replacement intervals and carry out cost efficiency analysis. The Project Services process methodology for commissioning requires the completion of CMMS forms and handover requirements from the PMSP to the PLMSP before/during the substantial completion meeting INFRASTRUCTURE ONTARIO – 2015 Building Systems Commissioning Guideline 12 6. EXECUTION PHASE 6.1 OBJECTIVE The overall objective during this phase is to ensure that all building systems, or in the case of smaller projects, all systems in the area of work, are integrated and function as intended and that stakeholders are trained to operate the systems correctly, and that all objectives set out in the commissioning plan are achieved at Substantial Performance. 6.2 COMMISSIONING UP TO SUBSTANTIAL PERFORMANCE In the later stages of the construction work, systems and assemblies are installed, inspected, tested and placed into service to meet the project design requirements. The key steps in the execution phase with the participation of a commissioning authority, in order to achieve Substantial Performance, are: • • • • • • • • • • 6.3 Ongoing refinement of the commissioning plan – within the limits permitted by the contractor’s construction contract. Orderly startup and functional performance verification of designated systems Correction of deficiencies, including those identified during commissioning Coordination and compilation of the commissioning documentation during startup, verification and performance testing stages, and completion of the CMMS verification forms for new systems installed. (Schedule D) Stakeholder training (Schedule G) Submitting and approval of O&M manuals. (Schedule B) Completion of requirements for Substantial Performance Completion of activities necessary to achieve LEED certification, where applicable Completion of Instrument 3.2.1 T1 - Commissioning Verification Form (Schedule E) Completion of Instrument 3.1.4 T2 - Project Handover Checklist (Schedule H) COMMISSIONING BY THE CONTRACTOR In Lieu of a Commissioning Authority Except for new or upgrade projects to Building Automation Systems (BAS), for projects that doesn’t have any Design Consultant engagement, the commissioning will be implemented by the contractor and trades in compliance with the commissioning plan, and in accordance with instructions included in each trade section of the specifications, refer to schedule A for exemptions. All activities noted above will be followed in accordance with the project charter requirements, notwithstanding the absence of oversight by a formal commissioning authority. The commissioning reports for commissioning up to Substantial Performance will be submitted under the cover of a “Commissioning Verification Form” which can be downloaded from the PMO Web Portal. INFRASTRUCTURE ONTARIO – 2015 Building Systems Commissioning Guideline 13 7. CLOSE-OUT PHASE POST OCCUPANCY COMMISSIONING: Post Occupancy Commissioning during the close out phase of the project begins at substantial performance and may continue through to the end of the contractual warranty/correction period. It is required where additional performance testing is needed because of seasonal changes, or varying building occupancy loads, or occasionally where all parties have agreed that substantial performance can occur before all systems have been constructed. Similarly, post occupancy commissioning in a registered LEED project may only be managed by an independent commissioning authority. The activities of all participants in the commissioning process throughout the execution phase will generally follow the principles set out in ASHRAE Commissioning Guideline 0, other than situation-specific differences for IO projects noted herein. The key steps to achieve this with the participation of a commissioning authority are: • • • • • • • • • Oversight of the commissioning activities by the commissioning authority Witness orderly startup, verification and testing of designated systems for equipment installed during the Post Occupancy Commissioning. Correction of remaining deficiencies, including those identified during commissioning. Coordination and compilation of the commissioning documentation during the fine tuning and performance testing stages, and completion of any outstanding CMMS verification forms. (Schedule D) Completion of any remaining stakeholder training (Schedule G) Submittal of remaining items for the O&M manuals(Schedule B) Completion of activities necessary to achieve LEED certification where applicable Completion of Instrument 4.1.3 T1 - Post Occupancy Commissioning Verification Form (Schedule F) Update of Instrument 3.1.4 T2 - Project Handover Checklist (Schedule H) – Completed earlier in Execution Phase If the project is registered for LEED certification, in accordance with the Government directive on LEED, the O&M manuals must include a re-commissioning manual that prescribes on going testing to maintain the performance levels established for LEED certification. The commissioning reports for post occupancy will be submitted under the cover of a “Post Occupancy Commissioning Verification Form” downloaded from the PMO Web Portal.

Infrastructure Ontario (IO) oversees the execution of ministry funded and capital projects that deliver the Ontario government’s needs for infrastructure investment, maintenance and renewal across the portfolio. 2. IO has contracted with Project Management Service Providers (PMSPs) for the project management of certain construction and construction-related services. IO provides project oversight and project management advisory services over the Project Management Service Providers. IO also directly delivers specialty projects on behalf of its clients. 3. IO has adopted sustainable and smart green design strategies which establish a basis for incorporating the principles of environmental stewardship, energy efficient and resource conservation into the design of new retrofit or renovation projects. IO is committed to a resource and energy conservation program based on continual improvement in the design and construction of new buildings and major renovations. PURPOSE 1. The purpose of the IO Building Systems Design Guideline is to standardize design and construction objectives and technical requirements across the full portfolio of IO buildings. To ensure higher performing buildings are designed and constructed in accordance with the Smart Green Portfolio strategy, to ensure consistency and to integrate all relevant IO guidelines and systems. This in turn will help our organization and our partners achieve the following: 1.1. 1.2. 1.3. 1.4. Increased occupant comfort and satisfaction Improved operational performance Improved energy efficiency Provision of technologies and tools to efficiently monitor, control and manage building systems. THE SMART GREEN PORTFOLIO STRATEGY 1. The Smart Green Portfolio Strategy is a high performance building portfolio strategy that utilizes advanced automation and integration to measure, monitor, and control building systems in order to optimize operations and maintenance at the lowest cost and environmental impact over the building lifecycle. 2. The Smart Green Portfolio involves integrating relevant building systems including, but not limited to, HVAC, Lighting, Security, Elevators, Fire Protection and Life Safety where possible to reduce energy consumption in a facility. 2.1. For example the Security card access system would communicate with the HVAC, Lighting and Elevator systems to identify staff entering the building, confirm what floors the staff have access to, and provide lighting and HVAC to the area where the staff resides. 2.2. Common occupancy sensors would be used by a variety of systems to turn lighting on and provide heating, cooling and ventilation only in occupied zones. 2.3. This allows for fine tuning of the operating systems based on “occupancy and schedule” versus the traditional “schedule” only approach. This results in significantly more energy savings at the facility. 3. The Smart Green Portfolio Strategy includes the infrastructure required for centralized remote monitoring of building systems. 3.1. The combination of integrated automation with centralized monitoring allows for all relevant building system information to be available to a supervisor for alarm and event management, troubleshooting, dispatch for service or repair, historical record keeping and utility metering including sub-metering for individual tenants. 3.2. Centralized building supervision results in faster response times, consistent implementation of policies and procedures, improved operational performance, and continuous energy efficiency optimization. INFRASTRUCTURE ONTARIO – 2015 Building Systems Design Guideline 4 TYPES OF PROJECTS 2 1. IO’s real estate portfolio includes 6,500 buildings and structures with a total area of approximately 50 million ft . The portfolio includes a wide variety of building types, sizes and ages. Building types range from office buildings, courthouses and laboratories to Ontario Provincial Police detachments and healthcare facilities. 2. The Guideline is applicable to all types of projects including: 2.1. System/equipment replacement and refurbishment 2.2. Renovations 2.3. Additions 2.4. New construction 3. The guideline covers different stages of projects: 3.1. Studies must identify existing building conditions and identify available options based on performance, efficient operation, operating, and capital costs. The options identified in the study shall include Life Cycle Cost Analysis, payback, implementation and preventive maintenance costs, energy savings, and return on investment up to a 25 year period, with a full integration with this guide. 3.2. Design solutions are to be based on the studies and confirmed by the Design Engineer. The design engineer is responsible for the overall design and performance and integration of building systems to ensure that they are specified, installed, commissioned and equipment is operating within their design intent, with a full integration with this guide. 3.3. Building systems installations are to ensure that the contractor has supplied and installed the equipment and is operating as originally specified and intended. The contractor and consultant are to ensure that final sequence of operations are completed and adjusted throughout the commissioning and warranty process as required. INFRASTRUCTURE ONTARIO – 2015 Building Systems Design Guideline 5 THE GUIDELINE CONTENT AND ORGANIZATION 1. The Guideline organizes Building Systems components into the following seven Divisions, per the 2012 CSI MasterFormat practice: 1.1. Division 21 Fire Suppression 1.2. Division 22 Plumbing 1.3. Division 23 HVAC 1.4. Division 25 Integrated Automation 1.5. Division 26 Electrical 1.6. Division 27 Communications 1.7. Division 28 Electronic Safety and Security 2. Users may need to refer to multiple Divisions for details on a particular sub system (e.g., fire alarm system panels, controls and devices associated with Division 21 is found in Division 28). 3. The organization of each Section also is aligned with the 2012 CSI Master-Format and includes the Section Names and Numbers for each Division by Construction Specification Canada (CSC). 4. For each Section, the Guideline includes check boxes to identify if the relevant Section: 4.1. “C” - complies; 4.2. “NC” - does not comply; or is 4.3. “N/A” - not applicable for the project. THE METHODOLOGY IN STEPS 1. PMSP to ensure Infrastructure Ontario is being informed about up coming steps. Project Review Communications with regards to the three (3) steps to be sent to Project.Review@InfrastructureOntario.ca indicating the project number in the Subject line of the communication. Final Tender Document to be sent to same email. 2. Step 1: At the beginning of the Project (When PJ is received) 2.1. To initiate the process, Project Management Service Provider (PMSP) requests the applicable sections of the IO Design Guidelines from IO Property and Land Management Service Provider (PLMSP). 2.2. The PLMSP selects the applicable sections that apply to the project and sends them to PMSP. 2.3. The PMSP will provide the selected sections of the Guideline to the Design Consultant at the start of each project. 2.4. The Design Consultant acknowledges the receipt of the selected Section(s) 3. Step 2: At 33% Design 3.1. PMSP and its vendors (ex: The Design Consultant) discuss the application of the IO Design Guideline sections by checking one of the following boxes: 3.1.1. “C” - in compliance with the Guideline design criteria; 3.1.2. “NC” - is not in compliance or 3.1.3. “N/A” - that the selected section is not applicable for the project. 3.2. Documents for review shall include: 3.2.1. Basis of Design along with Schematic Design 3.2.2. Design Calculations in case of Change of Use or major equipment replacements (e.g. Chillers, Boilers, Air handling units, etc.) 3.3. Project Management Service Provider (PMSP) reviews the design criteria with Project Designer and IO Property and Land Management Service Provider (PLMSP) 3.4. Consensus is required in order to proceed with the rest of the design. 4. Step 3: At 98% Tender Document (including detailed Specifications) 4.1. PMSP and its vendors to verify that Project bid documents (Specifications, drawings, commissioning Req., ext. ) meets the discussed and agreed upon guidelines and variations are documented as discussed in Step 2 INFRASTRUCTURE ONTARIO – 2015 Building Systems Design Guideline 6 APPLICATION AND LIMITATIONS 1. When an “NC” is checked, the Design Consultant should document in the notes section at the end of each Division why the design is not compliant and the reason alternative design is selected. Any alternative designs must be discussed and accepted by IO and its representatives prior to implementation. 2. In this way, the Guideline provides a comprehensive document for each project that identifies the full scope of the Building Systems and the specific design requirements for each component and system. 3. The Guideline can then be used throughout the design and construction process as a guide to continuously check that the design requirements agreed at the start of the project are fully implemented by the end of construction for Commissioning purposes. 4. The Guideline is not intended to limit input from the Design Consultant or prohibit the use of alternative systems, methods or devices not specifically prescribed. However, it is important that alternative systems continue to meet or exceed the intent of the Guidelines and the Smart Green Portfolio strategy. 5. The Guideline is not a substitute for construction specifications. The Design Consultants remain fully responsible for preparing drawings and specifications that are fully compliant with applicable codes and standards. LIFE CYCLE COST ANALYSIS 1. Life Cycle Cost Analysis is a valuable tool used to compare various options on their total cost (including capital, operating, maintenance, and replacement costs), measured as a net present value over a set time frame. Life Cycle Analysis identifies those products and systems that offer the greatest sustainability and long term value. 2. For these reasons, IO requires the Design Consultant to provide Life Cycle Cost Analysis (LCCA) for selected major Building System components and systems during the concept stage of the project. Examples of systems to be considered include: 2.1. Central plant versus distributed terminal systems (eg. central plant versus distributed heat pump) 2.2. Alternative energy systems (solar voltaic, solar thermal, fuel cell) 2.3. Central air handling versus compartment unit or fan coil 2.4. High efficiency equipment (condensing boilers, magnetic bearing chillers) 2.5. Lighting sources and controls (LED, induction, dimming, day-lighting) 2.6. Electrical distribution 2.7. Enhanced building envelope and shading 3. The Life Cycle Analysis will be performed using an accepted methodology such as described in Chapter 37, Owning and Operating Costs, of the 2011 ASHRAE Handbook for HVAC Applications. DESIGN OPTIONS 1. For many projects, multiple design solutions are available and should be evaluated during the early stages of design to determine the optimum solution for the project. 2. On this basis, IO requires the Design Consultant to identify Design Options and evaluate these options. The analysis should include capital cost, life cycle cost, energy efficiency and performance advantages and disadvantages. IO COMMISSIONING GUIDELINE 1. The Guideline includes references to the IO Commissioning Guidelines for each Division. The IO Commissioning Guideline describes the commissioning process required for the entire project life beginning with project identification; program planning, execution and final close out. The Commissioning Plan for each project will be customized to suit the specific project in accordance with the Commissioning Guideline.
