Contact

National Foundation Authority maintains a public reference point for inquiries related to the foundation services directory, contractor listings, and the structural scope of this resource. This page describes the available communication channels, the geographic coverage of the directory, and the information that should be included when submitting a inquiry to ensure an accurate and timely response.

Additional contact options

Beyond direct messaging, the directory supports inquiry routing through structured submission forms tied to specific topics within the foundation services sector. Inquiries that fall into distinct categories are handled through separate pathways:

1. Listing corrections or updates — Contractors, engineers, or licensed professionals who identify inaccurate credentials, lapsed license data, or outdated service area descriptions in an existing listing should route inquiries through the listing correction pathway.
2. New listing submissions — Foundation contractors operating in the United States who meet applicable state licensing thresholds may submit qualification documentation for directory review.
3. Research and reference inquiries — Researchers, journalists, or regulatory analysts seeking clarification on how the directory classifies foundation system types, contractor credentials, or inspection-related data should use the research inquiry channel.
4. Permitting and code reference questions — Questions touching on the International Building Code (IBC), International Residential Code (IRC), or state-level amendments to those model codes should be directed to the code reference inquiry channel, not the general contact form.

The directory does not provide legal advice, engineering opinions, or project-specific structural assessments. Inquiries that request those services are outside the scope of this reference resource.

How to reach this office

National Foundation Authority operates as a national-scope reference directory within the construction vertical. The primary contact mechanism is the web-based inquiry form available on this page. Response timelines for standard inquiries are typically measured in business days, with listing correction requests receiving priority processing given the public-record implications of inaccurate contractor credential data.

Inquiries related to safety standard classifications — including those referencing OSHA 29 CFR Part 1926 Subpart P (Excavations) or ASCE 7 structural load standards — are routed to the editorial reference team rather than the general inbox. This distinction matters because foundation work intersects with regulated excavation safety, soil classification requirements, and engineered load calculations that carry distinct compliance framing under federal and state codes.

For directory structure questions — including questions about how the Foundation Listings are organized by foundation system type (shallow versus deep foundation classifications, spread footings versus driven piles versus drilled shafts) — the reference inquiry form is the appropriate channel.

Service area covered

The directory covers foundation contractors and related structural professionals operating across all 50 United States. Geographic coverage is organized at the state level, with secondary classification by regional soil and seismic conditions that affect foundation system selection and permitting requirements.

Soil classification zones relevant to foundation design — including expansive clay regions concentrated in Texas, Colorado, and the mid-South, and high-seismic zones designated under ASCE 7 along the Pacific Coast and the New Madrid Seismic Zone — are reflected in the directory's contractor specialty tags. Contractors whose licensing and project history demonstrate experience with specific geotechnical conditions are distinguished from general foundation contractors in the listings.

Permitting authority in the United States rests with local jurisdictions — typically county or municipal building departments — that adopt and amend model codes including the IBC and IRC. The directory references these jurisdictional structures but does not replicate or replace official permit records. For permit verification, the authoritative source is the issuing jurisdiction's building department.

The directory does not cover foundation contractors operating exclusively outside the United States. International project inquiries are outside the current geographic scope.

What to include in your message

Effective inquiry submissions contain specific, verifiable information. Vague or incomplete submissions extend response timelines and may not receive a substantive reply. The following breakdown applies to the most common inquiry types:

For listing corrections:
- The contractor or company name as it appears in the current listing
- The specific field or fields requiring correction (license number, state of licensure, foundation system specialty, service area)
- The source document supporting the correction (state licensing board record, NCEES credential, or equivalent)

For new listing submissions:
- State-issued contractor license number and the issuing board name
- Foundation system specialties (e.g., driven steel piles, helical piers, drip-cast concrete piers, slab-on-grade, basement wall systems)
- Geographic service area by state or metropolitan region
- Any relevant certifications from named bodies such as the Deep Foundations Institute (DFI) or the Structural Engineering Institute (SEI) of ASCE

For code and permitting reference questions:
- The specific code edition in question (e.g., IBC 2021, IRC 2021, or a named state amendment)
- The jurisdiction, if the question is jurisdiction-specific
- The foundation system type the question pertains to

For research inquiries:
- The nature of the research project or publication
- The specific directory data or classification methodology being examined
- Any deadline constraints that affect response timing

Submissions that include the contractor's state licensing board name alongside the license number receive faster verification processing, because the directory cross-references state licensing data from authoritative sources including individual state contractor licensing boards rather than relying solely on self-reported credentials.
