I've been in design-build contracting for 6 years and my firm is encouraging the whole project management team to get certified. I started studying for the DBIA about 3 weeks ago and I'm working through the Body of Knowledge. The exam is 120 questions and I've seen passing scores around 68–72% mentioned in a few places, though I haven't found an official published cutoff anywhere.
The procurement and contracting section is where I feel sharpest since it's closest to my day-to-day work. Where I'm struggling is the design management module — specifically the design progression framework and owner vs. contractor design responsibility at different project phases. The line between preliminary design and bridging documents isn't always clear to me in practice, and the exam seems to test that distinction precisely.
I'm doing about 90 minutes a day and planning to sit in 5 weeks. Anyone who's been through it recently — how representative are the practice questions compared to the actual exam? I want to make sure I'm not drilling a format that doesn't match what shows up on test day.
I passed on my first attempt with a 74%. The procurement section was easy points for me too — qualifications-based selection, best value, request for proposals formats. Make sure you know the differences between all three delivery methods cold because comparison questions show up regularly.
The design management and risk allocation modules were hardest for me too. Particularly questions around GMP contracts and where design risk sits when you're doing a bridging approach. If you can get clear on that distinction you'll handle those questions much better.
5 weeks at 90 minutes a day is solid if you're coming in with real design-build experience. The exam rewards practical understanding over memorization. When I was unsure about an answer I'd think through what would best serve the integrated team and the owner's goals, and that framing got me through most of the gray-area questions.
The official DBIA practice exam is pretty representative of the real thing in terms of difficulty and question style. I found the actual exam slightly more scenario-based than the practice questions but the content areas were consistent. Don't neglect the project execution and team integration module — it's worth more weight than it looks.
Failed it the first time around, so I'll be honest about what tripped me up: I underestimated the team integration and collaboration section hard. I thought six years in design-build meant I already knew how teams worked, but the exam wants you to know the specific DBIA frameworks and terminology, not just your field experience. Spent way too much time on procurement and not enough on the softer side of it. This dbia/questions/team integration and collaboration practice set actually helped me see what I was missing before my second attempt.
Second time I passed with a 74%. What changed was I stopped reading the Body of Knowledge linearly and started doing timed practice questions by section so I could see exactly where I was bleeding points. The risk allocation questions also got me the first time — they look straightforward but the wording is tricky. If you've got the field background you're already ahead, just don't assume it'll carry you through without drilling the actual exam format.
Honestly, the Project Execution module got me more than I expected. I'd been in design-build for years so I figured I knew it, but the exam tests you on the DBIA framework specifically, not just general contracting intuition. There's a difference between how you actually run projects day-to-day and what the Body of Knowledge says the process should look like, and that gap is where I kept missing questions in practice.
The thing that actually turned it around for me was stopping trying to memorize the content and instead asking "what would a DBIA-certified project manager prioritize here?" For the risk and procurement stuff especially, the answers that felt wrong from a field perspective were often the right ones according to the framework. Once I started thinking that way my practice scores jumped pretty fast. Give yourself time to internalize that mindset shift and you'll be fine.
Just passed mine two months ago, and honestly the risk allocation module wrecked me more than I expected. I've been doing design-build contracts for years and thought I'd breeze through it, but the exam goes way deeper than everyday project work — it's really testing whether you understand the why behind how risk gets distributed, not just what your firm does in practice.
The one thing that actually made the difference for me was drilling practice questions under timed conditions starting about two weeks out. Doesn't sound revolutionary, but I kept reading the BoK chapters and feeling confident, then bombing the practice sets because I wasn't used to how they word things. Once I shifted most of my study time to questions over reading, my scores jumped fast. If you're already three weeks in, I'd make that switch now.
