package. The general contractor uses these skills to keep the project running on time, within budget, and in accordance with the plans and specifications provided by the owner's design professionals. However, if there are errors or omissions in the plans and specifications that were not discovered prior to construction, the contractor is not liable for any resulting cost overruns or time delays.

      On the other hand, construction management may be contracted by the owner as a professional service separate from the work of the general contractor. In this case, part of the construction manager's job is to review the plans and specifications before construction begins. Doing so will reduce unwanted consequences and repercussions resulting from a lack of oversight by a construction professional. Construction management in these circumstances is usually provided as a distinct service or project delivery method.

      I realize that much of this may seem a bit confusing right now, but later in the chapter I will spend time discussing the various project delivery methods and the functions of construction management. For now, I just want you to understand that many different people perform construction management services. This group of people includes general contractors, subcontractors, project managers, construction managers, construction estimators, general superintendents, job foremen, safety officers, quality control managers, and many other construction professionals. It takes a whole team of players to manage the construction project.

       NOTE

       Throughout this book, when I use the term construction manager, project manager, or constructor, I am referring to any one of the entities that delivers construction management services: the general contractor, the construction management team, the construction management firm, or any individual construction manager trained in all aspects of construction management.

      As discussed in Chapter 1, construction projects are extremely diverse and come in every size, shape, and flavor. However, some characteristics about construction projects are common to all types, and these characteristics clearly distinguish them as unique from other industry sectors.

      When we build a computer, a piece of furniture, or even an airplane, we typically build a prototype first and then test it and work out the bugs before we put it into production. We do all of this under controlled conditions, using state-of-the-art mechanics, robotics, and technology. These projects are usually built utilizing a relatively constant workforce, standard parts, and stable materials.

      Now let's take a look at the construction project. Every project is built as a one-of-a-kind facility, which means that each is built on a different building site, under variable weather conditions and particular environmental and topographical conditions. Each one is a prototype in and of itself. There is no testing it first to make sure it works. Instead, the bugs get worked out as we go. Our workforce is primarily transient practitioners of an assortment of trades moving from job to job as assigned, coming in and out of the process at various stages throughout the duration of the project. Although more automation is being utilized, for the most part, our labor is still performed by the human hand—laying the brick, forming the concrete, and setting the steel. Finally, many of our materials, such as lumber, concrete, and steel, are sourced from nature-made components. They react to the heat, the cold, and the humidity on any given day.

      In spite of these uncertainties and unique circumstances affecting the project, a construction manager is expected to deliver a high-quality facility on time, within budget, and accident free. That's one heck of a management challenge, to say the least! But let's identify exactly what it is that we are trying to achieve. The primary objective of the construction management function is to control three main factors or values. They are time, cost, and quality. These three factors are commonly referred to in the industry as the three-legged stool.

      However, there is actually one more very important factor, and that is safety. Construction can be a dangerous business, and safety must be the foundation upon which all other values are placed; without it, the whole project is at risk.

      Let's take a closer look at all the factors that influence the construction project and how the construction manager considers each of them as part of the management challenge.

      Project Values

Illustration depicting the six dials of project value in a construction business: cost, time, quality, safety, scope, and function.

      The idea is that each of these dials has a most advantageous setting for any given project, and it is the project team's job to optimize these settings. As noted earlier, only the first four project values are within the traditional range of services provided by the construction management team: cost, time, quality, and safety. The last two, scope and function, are typically determined by the owner and their design team prior to the construction manager being involved. However, some project delivery methods bring the construction professionals onto the team early in the process so that they may assist with scope definition, overall function, and programming. I will discuss project delivery in greater detail later in this chapter.

       NOTE

       Although the Collaborative Process Institute (CPI) is no longer a functioning organization, its work and the ideas that came out of those first meetings are noteworthy and, in my opinion, reflect current trends in construction management.

      These dials of values and how they are monitored and controlled are illustrated in the following list. The Collaborative Process Institute describes them as follows:

       Cost It is essential to predict and control what the construction project will cost. Costs are established, targeted, and controlled by means of an estimate or budget. As the work progresses, expenditures for materials, labor, equipment, and subcontracts are tracked and measured against the estimates. The fundamental goal is to maintain costs within or below budget parameters. The construction manager who can minimize cost while maximizing overall value to the owner will optimize the cost dial.

       Time As the saying goes, time is money. For many projects, the speed with which the building can be brought on line is more important than almost any other factor. Time is monitored and controlled by a detailed schedule, breaking each item of work down into its component parts. Once all of the purchasing, fabrication, installation, and construction steps are identified, a time element is assigned to each step. The goal is to complete each of the work items within the time frame assigned.The construction management team that can guarantee the schedule and actually beat it is invaluable to the owner.

       Quality Quality is the grab bag that covers all the aspects of the building not addressed by the other five values, such as aesthetic impact, user perceptions, appropriateness of building materials, and so on. Quality is monitored and controlled by a variety of means, including specifications, punch lists, inspections, tests, and user surveys. Special care must be taken to establish appropriate measures early in the project to focus attention and effort on the quality expectations of the team.

       Safety No matter how valuable a facility or structure may be, it is never more valuable than the health and welfare of the people who build and use the building. Care
