CDI Corp (CDI Corporation) is a multidisciplinary engineering and technical resourcing firm founded in Philadelphia in 1950 as Comprehensive Designers, Inc., later listed on the NYSE from 1988 to 2017. After being taken private by AE Industrial Partners in September 2017 for approximately $176M ($8.25 per share), AE divested CDI's aerospace business to Belcan (2017), talent and technology services to Artech (2018), and architecture/engineering subsidiary L.R. Kimball to TranSystems (2021), refocusing the remaining CDI Engineering Solutions on integrated engineering, design, project support, procurement, and construction management for the energy and chemicals industries. On January 1, 2025 CDI Engineering Solutions, LLC became a wholly owned subsidiary of Tata Consulting Engineers and now trades as Tata Consulting Engineers USA, LLC, headquartered in Houston, TX with 650+ employees across ten engineering centers. CDI Corp has no public developer APIs; the company delivers engineering services and staff augmentation rather than software products. The tagline carried by the operating business is "Quality Results. Sustainable Solutions. Safely Delivered."
CDI Corp is profiled on the APIs.io network. Tagged areas include Engineering Services, Technical Staffing, Energy, Chemicals, and Project Services.
Regulatory Posture applies to this provider. Its tags matched the
Energy & Utilities regime, so
Regulatory Posture carries 15 points of the composite.
If this regime is wrong for your business, say so on your
provider repo — the
applicability map is public and we will correct it.
Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for
this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero:
never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and
several others — scorable at all.
The six quality facets above are damped to 85 points between them,
because the conditional facet above carries the other
15. That is why each facet's contribution is shown against a damped
maximum: raising a quality facet moves the composite by 85% of its nominal
weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/cdi-corp: open an issue to ask a question, or submit a pull request to add artifacts.
