Expert testimony standard in Colorado

Colorado applies a Daubert-type reliability-and-relevance inquiry under CRE 702; courts may, but need not, weigh the specific Daubert factors.

The judge gatekeeps both the method and how it was applied to the facts. That scrutiny reaches experience-based technical opinions like a contractor’s, so the report has to show its work: what was inspected and measured, which code edition and manufacturer requirements it was measured against, and why the alternative causes were ruled out.

Federal courts in Colorado

Federal courts apply Federal Rule of Evidence 702, amended December 1, 2023 to make explicit that the proponent must show each admissibility requirement is more likely than not met — including that the opinion reflects a reliable application of the method to the facts. Retained experts produce a written report under Rule 26(a)(2)(B).

Because Colorado state courts and the federal courts both apply a reliability-based test, a report written to the federal standard generally travels between forums — but state gloss on the rule still controls in state court, and counsel will flag where Colorado departs from federal case law.

Construction claim deadlines in Colorado

• The Construction Defect Action Reform Act (C.R.S. §13-20-801 et seq.) imposes notice-of-claim and inspection steps before suit against construction professionals.
• Claims against licensed professionals require a certificate of review (C.R.S. §13-20-602).

Repose usually runs from substantial completion, so commissioning records, certificates of occupancy, and startup reports are often the first documents we ask for — they fix the clock and the as-built condition at the same time.

Expert disclosure in Colorado practice

Expert disclosure in Colorado state courts follows the state’s civil rules and the case scheduling order, which set the form of disclosure and the deadlines case by case. We work to the order counsel provides and assume every field note, photograph, and data export may be produced.

Who sets the contractor standard in Colorado

Colorado has no statewide HVAC contractor license; mechanical licensing and code adoption are local (Denver and other jurisdictions), so the standard is measured jurisdiction by jurisdiction.

We measure work against the code edition in force at permit, the manufacturer’s installation and maintenance requirements, and what a reasonable, qualified contractor would have done in Colorado. Where a question turns on engineering judgment, or a Colorado statute requires an affidavit from a licensed design professional, we engage a Professional Engineer licensed in Colorado. We do not perform repairs on matters we investigate.
