The number everyone cites does not exist.
Write anything about productivity in this industry and you hit the same wall. You want to say what share of a licensed professional's week goes to design versus administration. You go looking for the study. There isn't one.
What exists instead:
- Utilization rate — the share of paid hours that are billable. The industry median is 58.9% across roughly 900 firms (Deltek Clarity, 47th edition). It is a real and useful number, but it tells you only that 41.1% of hours were not billed. It does not tell you what those hours were spent doing, and it says nothing at all about how the billable 58.9% divides between design, coordination, documentation and rework.
- The $177 billion figure — that construction professionals lose 35% of their time to non-productive activity. Widely quoted at design professionals. The surveyed population was 49% general contractors and 36% specialty trades. It is not a study of designers.
- Vendor case studies — company-reported, unaudited, and selected for the result.
The gap, stated plainly
There is no published, methodologically transparent measurement of how architects and engineers allocate their working hours. The profession has been arguing about AI's impact on productivity without a baseline to measure impact against.
This study is designed to produce that baseline — and to make it citable by anyone, including people who disagree with us.
How we are running it, and why that matters
This page is published before data collection, deliberately. The instrument, the sampling plan, the analysis plan and the disclosure of who is paying for it are all fixed in advance and in public. That makes it much harder for us to quietly discard inconvenient findings later — which is the point, given that we have an obvious commercial interest in the answer.
Declared conflict of interest
Oxvelo is building an AI-augmented engineering practice. We benefit commercially if this study finds a large administrative burden, and we are disadvantaged if it finds a small one. That is precisely why the instrument is pre-published, why the raw anonymised dataset will be released alongside the findings, and why we invite anyone to re-analyse it. If the study finds that design professionals spend most of their week on design, we will publish that.
The instrument
Estimated completion time: 8–11 minutes. All questions optional except screening. No respondent is identified in any published output.
Section A — Screening and context
Section B — The core measurement
Drawing and model production
Checking, QA/QC and reviewing others' work
Code and standards research
Coordination with other disciplines or consultants
Client communication and meetings
Internal meetings and management
Proposals, fee estimates and business development
Contract administration — RFIs, submittals, change orders
Document control, filing and searching for information
Timesheets, invoicing and administrative tasks
Training, mentoring and professional development
Rework caused by errors, omissions or changed information
Other
Section C — Where the friction is
Section D — Tools and AI, asked last and deliberately
Section E — Optional identification
Sampling and methodology
| Parameter | Commitment |
|---|---|
| Target sample | Minimum 150 completed responses for publication; 400+ for discipline-level breakdowns |
| Population | Practising design professionals at US and Canadian architecture and engineering firms |
| Recruitment | Professional networks, discipline associations, LinkedIn, and direct outreach to firms. This is a convenience sample, not a probability sample, and every published output will say so |
| Known bias | Self-selection toward the digitally engaged, and toward people with strong views about AI. We will report the D1 adoption distribution against Deltek's firm-level figures so readers can judge the skew for themselves |
| Field period | Opens on release of this instrument; closes at 400 responses or 90 days, whichever is first |
| Question order | Time allocation (B) is asked before any AI question (D), so that thinking about AI cannot prime the core measurement. This is why Section D is last |
| Analysis plan | Medians and interquartile ranges, not means — the distribution is expected to be skewed. Cuts by discipline, firm size, seniority and fee mix. Pre-specified test: administrative burden correlates with firm size |
| Data release | Anonymised row-level dataset published as CSV alongside the findings, under a permissive licence |
| Corrections | Any error found post-publication is corrected in place with a dated changelog, matching the verification-log practice in our other reports |
What would make us wrong
Stated in advance, so it cannot be rationalised afterwards:
- If the constant-sum allocation shows design professionals spending more than 60% of their week on technical design and production, the "administrative burden" thesis is substantially overstated and we will say so.
- If C2 shows practitioners rating most of their non-design work as mostly judgment rather than repeatable, the automation-potential framing in Figure 4 of our report is wrong.
- If D4 shows widespread client fee pressure already, the commercial model in our report needs rebuilding, not defending.
Take part
The study is open to any practising architect, engineer, or technical staff member at a design firm in the US or Canada. Responses are anonymous, the instrument takes under twelve minutes, and every participant receives the full dataset and findings before publication.

This instrument accompanies The AI-Augmented Engineering Firm, which sets out why the missing baseline matters and what currently stands in for it.
