A/E/C industry chat spaces frequently include questions about what projects a person can include in his/her resume and how much detail to provide as description. And at least half of the base resumes I see when my clients ship a batch of them to me for a proposal include things I believe with all my heart should NEVER appear in a person's professional resume.
The table above shows what I believe constitutes good content for a project description on an individual's professional resume. This is enough information to show the client/owner that you have done a project similar to their's at some point and served in a similar role to that which you will fill on their project.
Here are two samples of project descriptions I believe work for your resume.
New Big Box Store with Grocery, Anyplace, State. MEP Task Manager. Project involved planning and design for a big box store with a grocery and a variety of departments with different design requirements. Scope of work included mechanical, electrical, and plumbing design for the grocery, electronics, garden, and pet departments. Managed the team providing MEP design for the four specialty departments mentioned and interfaced with the rest of the design team.
Major Freeway on New Alignment, Anyplace, State. Engineering Manager. Project encompassed design and construction phase services for extension of a major freeway. The 15-mile long project traverses urban and suburban areas, and includes one bridge over a river and a number of overpasses crossing other roadways and railroad lines. Managed the civil, structural and electrical engineering teams providing design and multiple plan packages for phased construction. Also coordinated with the team performing environmental studies and providing permitting assistance.
Your resume is YOUR professional history. It is not about your current firm, or any other firm you worked for in the past.
No project description on your resume should ever have a sentence that begins "XYZ Firm," "XYZ Firm provided," "XYZ Firm performed," or anything else about your firm. The description of your firm's scope of work belongs in the "Firm's Relevant Experience" section of the proposal, not in your resume.
In addition, you can include any project in which you participated, no matter who your employer was at the time of that project. In my almost 40 years of managing and working on proposals for A/E/C firms, the one question no client has ever asked was, "Who wrote your paycheck when you worked on that project?"
In other words, the client doesn't really care whether you worked on that project in your current position or for some other employer some years ago. They just want to know that you have already worked on at least one project similar to their's, and hopefully in the same role you fill be filling on their project.
One final thought: I believe the SF 330 form got it right: only one page allowed per individual, with a maximum of five projects. This forces you to identify the projects in your portfolio with the most relevance to the project being pursued, and to keep the descriptions brief enough that the reader doesn't lose interest in how wonderful you are.
