commissioning plan construction

To be sure, discovery does occur regardless of the application of the commissioning process. Roles and Responsibilities. must be involved in reviewing and approving construction submittals, commissioning plans/checklists, systems manual, some on-site inspection, some of the No matter how well the equipment and systems operate at the onset, they will deteriorate without proper care, and may even be crippled by staff who do not have sufficient training or resources. Furthermore, if discovery occurs before the construction contract is accepted as complete, the consultants and contractors will bear the burden of taking corrective action and generally all related costs. Reviewing the BoD verifies that the design team correctly understands the OPR so that their design will be closer to the bulls-eye. The scope of commissioning, the commissioning budget and schedule, a preliminary commissioning plan, and the composition of the commissioning team are established during predesign, and the OPR is documented. The local legislative body may assign this function to another, or retain final approval of the CIP. The facilities manager called up the supply fan motor trend log as he spoke with the building manager. The Commissioning Plan, like the OPR or CFR, is a living document that will need to be updated throughout the project by the CxP. The mechanic had adjusted the sheave the wrong way, slowing instead of increasing fan speed. Specifically, it is important to know of successful commissioning projects of similar facility or system type, complexity, and sophistication. A rule of thumb for initial estimates of the first cost of the building commissioning process is to allow between 3 and 4 percent of the mechanical system construction cost, plus 2 to 4 percent of the electrical system construction cost. Requirements of the validation process. The draft version of the Cx Plan for this project was produced by the Commissioning Authority (CxA). In addition, six specific items should be required in the submittals from respondents: Furthermore, the advertisement should state that finalists to be interviewed will be required to present comprehensive evidence of prior project commissioning schedules, executed test procedures and commissioning specifications that they created, and a final report. Asking each staff member at the end of a training session to demonstrate how to perform a task or where to find information keeps trainers and trainees fully engaged in the learning process. The 4-H Name and Emblem have special protections from Congress, protected by code 18 USC 707. The commissioning process outlined in this updated Whole Building WebIt is critical for the project engineering and construction teams to buy into the overall system commissioning plan. During construction, the commissioning authority performs a quality assurance role relative to the contractors commissioning activities. Attachment to Owner-Architect Agreement Schedule of Design Deliverables by Phase, Written description including seismic analysis of existing building and proposed strengthening techniques. However, these agreements should be augmented to be much more specific about what the architect/engineer is expected to provide on completion of each design phase. When the commissioning consultant recommended a series of workshops to define the OPR, they resisted, saying they had already spent way too many hours in meetings discussing programming, and that they could not imagine how further time could be spent productively. Complete allegiance must be to the owner. 125.3851) This is often done by producing a. In fact, in most projects, commissioning impacts the sequencing of the design and the construction. Subdivision (site-condo) reviews as well as development of a land division / subdivision / site-condo ordinance (M.C.L. The challenge here is that some owners, particularly in the institutional realm, provide standardized general and supplemental conditions language to the design consultants with the expectation that the language be included verbatim. It is important to identify the nature of the construction project to be commissioned. This chapter discusses the commissioning process applied to new construction and major renovations and when and how it should be applied, suggests how to acquire commissioning services, compares costs and benefits, offers steps for getting started, and provides links to resources for more information. Commissioning test specifications depend on the particulars of the systems, especially the sequences of control. The figures are based on an approach in which an independent commissioning authority, the designers, and the contractor shared responsibility for mechanical systems commissioning. An end-result-focused commissioning effort would have missed the opportunity during design to reduce the plant capacity to better match the load. WebCommissioning plans are vital in ensuring that complex systems and facilities operate safely, efficiently, and effectively. Along the way, the sustainable future movement recognized the importance of the commissioning process. A brief summary of the recommended specification sections follows. When the bulls-eye is clearly defined, we hit it more consistently. Traditional O&M manuals are long on exploded parts views and maintenance schedules for individual pieces of equipment and short on discussions about how the various pieces of equipment work together as a system. This has the added benefit of making the O&M materials available for training and inclusion in the systems manual. Bourassa, N. J., M. A. Piette, and N. Motegi. The Owners Commissioning Authority and the Contractor are responsible for developing the final Commissioning Plan and executing all commissioning activities. Design Phase A. 125.3865). In the design phase, the commissioning authority should review each design submittal for compliance with the OPR, maintainability, serviceability, and physical provisions for testing. Additional information on preservation overlays, concrete slab Detailed performance criteria helped a major university deliver environmental chambers that met researchers needs. 125.3841(3)). 2`dlt(dW3Y~:+p M7L4{aC'fhx1IrEqmF F~-ERz&^=6:EXe What are the functional requirements of these stations? Many planning commission meetings focus on zoning issues and from time to time discussion on the master plan. Over three years, these lost productivity figures may total as much as $1.38 per square foot, or 13.8 percent of the original mechanical contract. This is a request for qualifications and does not ask for cost proposals. The costs of not commissioning may exceed 20 percent of the construction costs of the uncommissioned systems when a broad view is considered. Communications and authority of the commissioning authority should be tailored to the level of involvement of the owner in the project. The commissioning process returns greater benefits at lower costs when it starts in a timely manner. Commissioning is no longer accomplished by a hero on a charging white stallion. In brief, the owner must make commissioning expectations clear during the predesign phases of each project, as expectations may vary with different kinds of projects. 3. The weakest link is the one excluded from a quality process. For a campus or system with multiple facilities and ongoing capital construction, standardizing the commissioning process bears rich fruit. Nor do they have any idea of how the O&M staff is organized and managed. The ACG Commissioning Guideline, 2nd Ed. Project programming establishes important parameters for a project, but generally does not fully answer the question, What is required for this project to be a success? The OPR augments the project program by adding quality and performance criteria for the success of the project. Commissioning includes testing, adjusting, and balancing verification, but goes beyond the experience of the average testing, adjusting, and balancing firm. The fire department of a large city recently embarked on a program to upgrade all of the citys fire facilities to meet heightened seismic requirements and to deal with other inadequacies. The commissioning coordinator hired by the general contractor schedules the contractors various commissioning activities and coordinates them with other construction activities, assembles project documentation, reviews the commissioning test procedures, and directs the correction of deficiencies. Serving approximately 8,500 students,(), Energy & Greenhouse Gas Tracking/Reporting, Learn More About SIQ Corporate Responsibility. The study concluded that the O&M costs of not commissioning ranged from $0.45 to $0.75 per square foot for the first three years of operation. However, coordination of commissioning requirements also reaches into the supplemental conditions of the contract and the general requirements in Division 01. Ideally, the project owners should engage the commissioning firm before the design and operation phase. Because the OPR information is so critical to the success of the project, the final OPR document should be included in the owner-architect agreement as part of the definition of deliverables. WebCourse Overview. We expect a reduced impact on our world from the construction, operation, use, and finally decommissioning of our facilities. Track staff hours spent during the first year or two of occupancy responding to trouble calls and other unscheduled O&M intervention. Start-up, installation verification, and testing provisions describe each activity in sufficient detail that an estimator can assign resources to establish pricing. The preferred answer is no. The commissioning process should be viewed as the primary quality process of the project. Instead of simply requiring a temperature sensor to be accurate, the criteria should specify a range of acceptable performance, such as within 0.5F of the temperature indicated by a calibration-grade instrument.. The key to translating a pilot project into standard operating procedure is success. Include Commissioning Authority name on Application. The Michigan Planning Enabling Act charges local government planning commissions with doing much more. The mismatch of capacity and load, however, would have shortened the life of a large, expensive chiller and consumed excess energy. The commissioning review should be completed in time for comments to be included in the design professionals formal submittal review response. Alerting bidders to the inclusion of significant commissioning requirements during the prebid meeting minimizes the likelihood that they will grossly underestimate the commissioning work in their pricing. Commissioning work need never be on the critical path except for a few days immediately before occupancy. Issued in furtherance of MSU Extension work, acts of May 8 and June 30, 1914, in cooperation with the U.S. Department of Agriculture. Because some of these deliverables are not universally understood by consultants, elaboration is necessary. create and implement a Commissioning Plan; incorporate commissioning in the construction documents; review Owner Project Requirements and Basis of Design; verify installation and performance of building energy systems; and So on the third project, the owner started commissioning in the design phase to try to reduce the number of design issues. To reduce the commissioning scope, cut the number of assemblies, systems, or features included in the commissioning scope, not the commissioning process activities. The process focuses on verifying and documenting that the facility and all of its systems and assemblies are planned, designed, installed, tested, operated, and maintained to meet the owners project requirements. hb```f``a` af`a0$FE Figure 1. Consequently, they designed a grossly oversized chilled water plant, served by a single chiller. The quality-focused approach to the commissioning process described in this chapter seeks to improve the delivery of a project at every step. ft. Show flexibility for expansion and alterations, Area tabulations compared to program requirements. The successful performance of a building requires coordinated, integrated design, construction, and operation of all building systems and assemblies. This chapter augments Guideline 0-2005 with information and perspectives useful to the higher education facilities professional. The Challenge Neshaminy School District covers 27 square miles in Bucks County and serves approximately 70,000 residents. The model for building commissioning derives from commissioning industrial facilities and naval ships. Document12093596 12093596. the slides. This haphazard approach results in a crazy patchwork quilt, with some bright crisp-looking pieces, some tattered and worn, and some just plain missing. Now the contractors and consultants have to make it work. 2. In the case of design consultants, for example, willing means that their responsibilities are defined in their agreements and that they are compensated. We believe its our responsibility to be good stewards of the environment and partner with our customers to make smart, sustainable decisions and help them reach their long-term facility goals. 125.3823 & 125.3819(2)). The commissioning schedule should not only show commissioning activities tied to project milestones, but should also indicate other design or construction activities upon which the commissioning activities depend. At the conclusion, they unanimously requested continuation of the workshop to finish working through all the questions. The owner must have the full allegiance of the commissioning authority during the project. Clear lines of communication and authority should be indicated in the contract. What the electrical engineering department really wanted was 40 watts per square foot in a small portion of the building to handle graduate computing rooms, but they also wanted flexibility to relocate the high-load rooms throughout the building. From soil testing to concrete slump tests, to weld inspections and X-rays, to masonry waterproofing performance tests, to landscape soil density and water retention tests, there are well-established procedures to evaluate the performance of systems, assemblies, and materials. The Cost and Benefits of Commissioning: One Owners Perspective. InSummary ReportNational Conference on Building Commissioning, April 2830, 1993, Sacramento, California. A comparison of this data with that of other recent capital projects that were not commissioned should be quite enlightening. The OPR document identifies some high-priority systems but may not provide sufficient information to fill in the lower ranks of the prioritization list. Subcontractors perform the commissioning tests and make corrections. Currently, controls are typically added to the design at the very last minute. The benefits of commissioning lie in the avoidance of the costs of not commissioning. Clearly, the typical delivery of O&M materials sometime after occupancy does not meet this need. Still, the architectural and engineering scope should require that the direction of the architectural and engineering team be consistent with the recommendations of the commissioning authority on commissioning-related issues. Make sure that someones job responsibilities include monitoring and maintaining the trend logs and reporting any need for action to a supervisor with the resources to handle the work. The bottom line is to make sure the contract has enforceable teeth and then insist on compliance with the contract. Sometimes it takes more incentive, like a commitment to provide some funding for the pilot project from the operations and O&M budget. The solution was simple and extremely effective. Commissioning ends at unrestricted opera-tions. This evaluation form can be used both in the original screening of submittals and during the interviews of the finalists. Review Commissioning Plan, PFCs, and FPT procedures. Pre-commissioning and commissioning has to be done for the entire system, along with the terminal facilities and supporting systems. From: Fundamentals of HVAC Control Systems, 2008 View all Topics Add to Mendeley About this page Plant Commissioning and Inspection In Lees' Loss Prevention in the Process Industries (Fourth Edition), 2012 19.1.13 Process Commissioning Budgets are tight. Specifications for commissioning encompass general, administrative, and technical requirements. At an annual payroll cost of only $200 per square foot of occupied space, if every fifth employee spent 30 minutes of work time per month on such activities (gripe sessions, letters of complaint, meetings, investigations, etc.) It provides master commissioning specifications as starting points for project commissioning specifications. In cases where the owner is only marginally involved in the day-to-day business of the project, it may be desirable to allow the commissioning authority to communicate with the architect directly on commissioning issues. Testing, adjusting, and balancing work is not commissioning. Respond to county request for copy of zoning (and updates as they happen) by the county planning commission (M.C.L. How does one counteract the bad press that results from lingering indoor air quality complaints in a new building? They are: This article was published by Michigan State University Extension. They sought to implement a standardized commissioning process for work at all the stations. While the term commissioning may not yet be a buzzword, it seems that many facilities professionals recognize commissioning as a means of improving the operation of their facilities. In some cases, the academic representatives had to refer the questions back to the primary investigators. A Commissioning Process can be split into 5 stages that detail, explains, defines, and set out for all parties the steps, tasks, responsibilities, and activities expected 125.3869). But the leak tests are prerequisites of other commissioning tests, so they must be scheduled, coordinated, and documented within the process of commissioning. Identify and Record Issues 2. The Facilities Standards for the Public Buildings Service (P100) establishes mandatory design standards and performance criteria for GSA-owned buildings. Traditionally, architectural and engineering agreements have been somewhat generic in their design and document deliverables requirements at each design phase milestone. The architectural and engineering team must participate in resolution of problems and conflicts during construction. The process of commissioning is relatively new to commercial and institutional building construction. In this case the commissioning authority would communicate formally with the designers through the owner. This is a function of the portion of the commissioning work that can be handled by the owners staff. These first costs include the services of the commissioning authority, additional services of the architect and engineers, project manager and/or construction manager, and the construction contractor for their support of the commissioning process. Testing and commissioning is to be carried out on installations to ensure that they are safe and meet the design requirements. Each of these duties are equally important as they are all part of the statutory mission. The same philosophy would apply with regard to the engineering and O&M representative. When the commissioning scope and the commissioning budget do not seem to align, as is frequently the case, either the scope must be reduced or additional funds must be committed. At the same time the request for qualifications is prepared, a selection evaluation form should be prepared. Buildings are aging and systems are failing. Other significant commissioning work during construction includes submittal reviews, installation verification and testing, generation of the systems manual and ongoing commissioning plan, and verification of owner training. The plan also describes continuous monitoring established during initial commissioning, with comments on how to respond to exceptional performance and how to update and maintain these trend and alarm log features. 37 0 obj <> endobj Required at submittal. However, some design issues seemed to be the result of inadequate communication of the owners expectations to the design team. The fact that not everyone has adopted a quality commissioning process can result in confusion in the marketplace, which is likely to persist for some years to come. Therefore, we recommend that if owners intend to provide standardized supplemental conditions and general requirements provisions, they do so no later than the end of design development. General quality review of the documents, including legibility, consistency, and level of completeness, Discipline-specific review for achieving the OPR, Specification applicability and consistency with OPR and BoD, $0.100 to $0.300 contractor (commissioning authority), $0.025 to $0.200 owner (operations staff), Local experience during the previous three years on projects of similar size and type, Resumes of personnel to be assigned to the project, with their corresponding project responsibilities, Detailed information regarding the onsite project manager. The study is organized to provide the transit agency and the project manager with a and more. Construction projects are in flux and there are many moving parts. The owner finally evolved to a mature commissioning process, which is well defined in American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE)/NIBS Guideline 0-2005,The Commissioning Process.1. During the construction and warranty correction periods, the commissioning team creates tools and documentation intended for use throughout the rest of the life of the facility. WebOutput. Improved orientation and training coupled with more useful documentation enables the staff to sustain the high performance achieved during the initial commissioning efforts. WebA list of 2023 Road Commission for Oakland County major road construction projects (list is subject to changes). Hire a planning director and/or zoning administrator (if in budget, if delegated to the commission) (M.C.L. includes examples of commissioning documents, test criteria, and test procedures. The SitelogIQ team utilizes mySiteIQ, our facility intelligence platform to provide critical knowledge of your building processes and systems to help align needs and maximize facility impact. The commissioning process evaluates the work of the design team as well as that of the contractors. The holistic perspective of the commissioning process also improves energy and utility performance by careful attention to the interface and coordination of the various building systems. WebG. Commissioning design reviews should be undertaken at strategic points in the design process, typically at the same milestones at which the owner reviews progress submittals (frequently schematic design, design development, and contract documents). INTRODUCTION. The controls example illustrates the technical content coordination challenges. 125.3823(2)). This narrative of the evolution of commissioning from a reaction to poor quality to a proactive effort to improve quality at each step of the capital acquisition process describes the growth of the state of the art over a period of some 30 years. It should also be made available to the construction contractor. Opportunities exist to perform installation verification and commissioning tests months before occupancy. The threat of mounting liquidated damages is a powerful inducement. Once it is recognized that all building systems must be commissioned, the process for doing so becomes specific and disciplined. It encompasses all activities that bridge these two phases including systems turnover, checkout of systems, commissioning of systems, introduction of feedstock, and performance testing. Re-commissioning; Retro-commissioning; Measurement & Verification; mySiteIQ Technology Platform; Construction Management. Failure of equipment due to infant mortality frequently occurs during the warranty correction period. Therefore, we need to include sufficient information about the contractors commissioning work in the bid documents so he or she can develop the pricing accurately and competitively. Review comments should be presented to the owner in writing and responded to by the designers, also in writing. Here at SIQ, were all about driving efficiency, powered by intelligence. Keep public records of its meetings and other documents, all complying with the Freedom of Information Act (M.C.L. However, when commissioning does start after predesign, the team has to play catch-up, trying to fill in missing information and performing tasks that should have already been completed. 125.3871). Requirements for lighting controls become more complex with each edition of the energy-conservation codes. There are multiple valid solutions to any design challenge. The authority of the commissioning authority should be limited to evaluating quality of the design, installation, or operation of the systems; identifying issues and evaluating proposed solutions to problems encountered; and recommending acceptance or rejection of test results. The plan for commissioning is discussed. These requirements are referred to as deliverables. Planning commissions have a large job that includes coordination, intergovernmental cooperation, master plan, zoning administration, infrastructure, land division, subdivision reviews and capital improvement planning all contribute to a master plan. Reference to commercial products or trade names does not imply endorsement by MSU Extension or bias against those not mentioned. The primary subgoal is to provide a safe and healthy facility for students, faculty, staff, and the public. The British Columbia Buildings Corporation representative cited the following mechanical systems commissioning cost estimates at the 1993 National Building Conference. WebThe GSA Commissioning Guide provides the overall framework for commissioning, from project planning through tenant occupancy. Virtually all sustainable ratings systems require some level of commissioning. On smaller projects, or with sophisticated GCs, the commissioning coordinator may be one of the GCs own staff. Identify regulatory requirements to be followed for testing and commissioning.
