WELCOME TO THE WORLD OF BIM FOR THE SUBCONTRACTOR
Building Information Modeling or BIM is the hottest topic in the construction industry and for good
reason. Architects use BIM tools and process to deliver better designs; engineers use BIM to ensure
designs meet codes and performance benchmarks; general contractors are using BIM to build projects
first on the computer before ever winning the job; and, owners are leveraging the “digital double” to
manage and maintain their facilities with more predictability and efficiency.
Clearly, BIM is changing the way construction professionals perform their individual tasks and more
importantly, how we collaborate, share and exchange information. BIM is directly influencing building
designs, functions and the ways in which buildings are built. Dozens of books, thousands of articles and
perhaps millions of “tweets” have been written about BIM in just the past couple years. Attend a
construction event (an actual conference or a virtual “webinar”) and you hear architects and GCs
describing how BIM is changing the way they design and manage construction projects. And yet, in this
barrage of BIM, little has been written about the impact on the subcontractor or fabricator.
Before we dig-in too deep in this article about BIM for the Subcontractor, let’s put a definition on what
BIM is and what BIM is not.
The popular use of the term BIM can be traced back to the CAD software vendors. The concepts of BIM
date back further, but the term gained popularity and has served as a means of differentiating the latest
generation of software from the (sometimes aging) CAD software. Initially (and in some cases still), the
term BIM is interchanged with a particular software package.
However, in this article the term BIM is used as a verb rather than a noun. BIM is used to describe the
activity of creating the building model. BIM is not a piece of software, or a database or a file saved on a
local computer or a server. Instead, BIM is the activity that involves significant process changes in the
design, engineering, fabrication, assembly and management of the built environment. BIM is Building
Information Modeling.
By definition, as a subcontractor or as a fabricator, you are responsible for only a portion of a building’s
overall design or fabrication. You must work with other subcontractors to ensure your system is
integrated, coordinated and compliant with the designs provided to you. If you are not using BIM, but
instead using 2D CAD and related disjointed processes, you are part of a labor intensive workflow,
where much of your effort is spent producing and updating drawings. These drawings and related
documents probably have high rates of inaccuracies and inconsistencies, many of which are often not
discovered until you show up at the jobsite. You produce these drawings for a variety of purposes
including design, engineering, manufacturing and assembly.
If you are a subcontractor who is not using BIM, you will find the same information is being entered into
computer programs multiple times, each time for a distinct and separate use. Some of this duplicate
data entry occurs within your company, and some of it occurs across the project team. If you are a
subcontractor not using BIM, you are limited by the tools and processes of the “pre-information age”.
Your long-term value to the project team is limited by these methods and your ability to differentiate
yourself, remain competitive, market your services and add value to the project team is limited by your
ability to squeeze efficiencies out of an inherently inefficient process.
But, if you are a subcontractor using BIM (whether or not the owner or GC has demanded it), you are
seeing significant improvements to the overall efficiency or your organization and the specific
productivity of your team members. You are adding value to the project team while at the same time
reducing, if not completely eliminating redundant processes. You have resolved the issue of manually
maintaining consistency across multiple drawing files by means of extracting the data and drawings you
need from the tools and processes of BIM.
If you are a subcontractor using BIM, you have connected the processes of design, engineering,
manufacturing and procurement. And you have connected these processes with the rest of the team.
The improved, and in some cases new processes you employ are recognized as a great contribution to
the efficient execution of the entire construction project and you will reap rewards from higher profits
and repeat business.
If you are a subcontractor using BIM, you have connected marketing and business development tasks to
your other core business practices and you are winning jobs and gaining market share while your “stuck-
in-the-CAD” counterparts are struggling to survive.
If you are a subcontractor using BIM, you have introduced new work processes that allow you to
prefabricate coordinated systems even in the most complex construction environments. Your ability to
prefabricate is shortening lead times while at the same time allowing you to get involved in the design
project earlier and at a deeper business level with the entire project team. BIM is enabling fundamental
process changes, because it provides you the power to manage the intense amount of information
required of “mass customization” which is a key concept of efficient construction.
And the greatest benefit to you, the subcontractor using BIM, is that BIM allows you to virtually design,
engineer, construct and fabricate your elements of the project. Your ability to Virtually Design and
Construct is not just an improvement, but a new way of working.
