My Building Was Commissioned. Why Am I Still Getting Complaints From The Building Occupants?

April 30, 2019

My first experience with the Commissioning V-Model was 10 years ago while interviewing with Hallam. It was being used as a visual tool to give me a brief overview of the Commissioning Process that we used. Being new to the field I took note of how effective the V-Model was.

Introduction

This blog entry is a portion of a white paper I have developed to help with a common question that I have heard from several building Owners, Owner’s Project Managers, and building occupants throughout the years:

If my building was commissioned, then why am I still getting complaints from building occupants?”

I was transitioning from being a nuclear trained Machinist Mate in the US NAVY working as a Quality Assurance Inspector on a submarine, and although the Commissioning/Validation Engineer position that I was being considered for had many similarities, there was still a lot to learn.

Progressing forward in my career the V-Model was an effective tool to keep sight of the big picture when focusing so closely on the finer details of each required task. We use this tool as a method of visualizing the Commissioning Process and giving a rough timeline of when tasks are performed as well as the general purpose for each task. It also details how each task relates to the others to accomplish the overall commissioning goal. I feel this could be useful to project Owners as well, and so this white paper was born.

I have worked on many projects, both large and small, throughout the North East. When it comes to both new construction and renovations, large teams are implemented to deliver the project to the Owner. Architects and Engineers design the space and building systems. Construction Managers and Sub-Contractors construct space and systems as specified in the design documents. The Commissioning Authority implements and documents the Commissioning Process. Of all the projects that I have been involved in, for the most part all team members were trying to complete the project on time, under budget, and to the best of their ability. So if an Owner hires only competent professionals to design, construct, and test their new building or space, what else can be done to reduce the number of complaints by occupants long after the project’s completion? The Commissioning V-Model can be used.

Commissioning Projects

For the purposes of the Commissioning V-Model commissioning projects are separated into the 3 main phases:3 main phases

  • In the Design Phase the project requirements are established. The OPR is written to define the facility’s intended uses and operation, measurable performance criteria, benchmarks, and success criteria. The Basis of Design (BOD) is written to document the calculations, concepts, and determinations along with equipment selections to meet the OPR. The design documents, such as the specifications and construction drawings, are generated in this phase. Other commissioning activities are also performed in this phase such as the development of the Commissioning Plan and the Commissioning Specifications, and also the design review is performed by the Commissioning Authority.
  • In the Construction Phase the Construction Manager, with their Sub-Contractors, begins erection and, if a renovation, demolition of the facility. The Construction Phase continues until construction is complete.
  • The Commissioning Phase begins within the Construction Phase and continues on after construction is complete. In the Commissioning Phase both the Construction Checklists and the Functional/Performance Test Scripts are generated and executed. Before those documents can be created the equipment submittals must be reviewed. Also in the Commissioning Phase the training matrix is developed and distributed to track owner training, a warranty review is performed to address any potential warranty issues prior to their expiration, and the systems manual is created for the owners use after turnover for insight into the construction, commissioning, maintenance, and operational information about the equipment and systems.

Commissioning V-Model

The Commissioning V-Model outlines the tasks performed in the different phases throughout the project. The “V” itself represents the lifecycle of the commissioning project; starting at the top left, moving down through the Design Phase to the bottom where the Construction Phase begins, then back up to the top right through the Commissioning Phase.Commissioning V Model

Commissioning documentation executed in the Commissioning Phase is designed to verify adherence to their corresponding design documentation.

In my white paper, I provide more detailed information on how to utilize the V-Model to guide the commissioning process. I also identify the three most common complaints from building occupants and how using the V-Model during commissioning can help to reduce these complaints from occurring.
