## ****AI Engineering Prompt: ****

****“ what are the standards for compliance in residential and commercial construction. Is there a standard set of credentials required for working in the construction trades. Specifics for accreditation in education and training in construction trades. This includes EPA and OSHA subject matter expertise in required subjective and objective areas of expertise for standard residential and commercial construction projects. In doing so please tell me about testing and skillsets requirements for millwright and millworkers. Use dataframes where warranted. I want to develop an education and training agent for the above mentioned career field. Standard testing design features and an application interface using python programming language for creating a set of testing platform. Any standard testing format and multiple choice UI architecture will work. As we proceed I will want to create a data warehouse and knowledge base for storing and managing project and subproject data. Furthermore, we should be able to apply this agent to other trades or professions with relative ease, for ingestion, processing, production and of data necessary for operating the various artifacts that will make up the modular design of this agent. Let’s pursue a studious theme, that is both technology friendly and in line with best practices. Buttons, colors and fonts should accentuate the purpose of the work for this the training set is designed. I should be able to identify the area of study, the standard training curriculum, a standard completion time and follow the most consistent domestic and international guidelines required. This will require use of Large Language Model Interface integration, some embedding (pinecone, chroma datastore) and means for both voice and text ingestion, processing and output. Use LangChain, LangGraph or LangSmith libraries python implementation. Final products will have undergone the CI/CD project management, i.e., GitHub, Git, life-cycle management system. This should get us started. As we continue we will add the ability to predict outcomes based on performance using standard metrics for subject professions. Okay, I’m glad to be working with you. It’s taken a few days for me to put together this prompt mentally, so feel free to add your perspectives and suggestions. I’m gonna walk across the street to our neighborhood McDonalds for the fam’s early dinner. I’ll be back as soon as possible to see which direction we’re headed. Thanks. Enjoy the mental, computational, logical, mathematical workout. Have fun with its creative feature delivery“. (Author: Darrell Hall, MD, MSCIS)****

### ****Awesome brief, Darrell — let’s get you a real foundation you can build on. I’ve (1) mapped the core compliance standards & credentials with citations, (2) added craft-specific skill/assessment matrices (incl. millwright & millworker), and (3) delivered a working Python starter pack (API + MCQ UI + CI) you can run today.****

Your tables are ready to view above (open the three DataFrames I displayed). And here’s a downloadable starter project:

Download the starter repo (zip)

1) Compliance landscape (U.S.) — what “standard” means

Model building codes & energy

Residential: IRC (one- and two-family). Commercial: IBC. Jurisdictions adopt specific editions; these pull in many referenced standards. ++ICC Digital Codes+1++

Electrical (all occupancies): NFPA 70 (NEC) — design/installation benchmark. ++NFPA+1++

Energy: IECC (separate residential & commercial provisions). DOE explains scope & applicability. ++ICC Digital Codes+2Energy Codes+2++

Accessibility: DOJ’s 2010 ADA Standards (civil rights law) + ICC A117.1 technical standard (often adopted via IBC). (Recent news removed some non-binding DOJ guidance, but ADA law & 2010 Standards remain.) ++AP News+5ADA.gov+5access-board.gov+5++

Worker safety (training you’ll test on)

OSHA 29 CFR 1926 (construction); OSHA 1910 for shops/fabs. OSHA Outreach 10-hour/30-hour cards are widely required (not “licenses”). ++OSHA+3OSHA+3OSHA+3++

Environmental (you’ll want explicit modules & checklists)

Lead (pre-1978): EPA RRP — firm cert + certified renovator + lead-safe work practices + records. ++EPA+1++

Asbestos: NESHAP 40 CFR 61 Subpart M (survey + 10-working-day notifications + handling) and AHERA/MAP accreditation for specific roles. ++Legal Information Institute+3eCFR+3EPA+3++

Stormwater: EPA 2022 CGP (NPDES) — SWPPP, inspections, NOI/NOT; some states run their own CGP. ++EPA+2EPA+2++

Specialty quality programs (commercial interiors)

AWI Standards & QCP for architectural woodwork/millwork quality certification. ++AWI Quality Certification Program+2Architectural Woodwork Institute+2++

⚠️ Licensure/contractor cards are state-specific (GC, electrical, mechanical, etc.). Treat state boards/AHJs as sources of truth during onboarding.

2) Credentials & accreditation (who issues what)

OSHA Outreach (10/30) — entry vs. supervisory safety awareness; delivered by authorized trainers. ++OSHA+1++

EPA RRP Certified Renovator + Certified Firm — required for paint-disturbing work in pre-1978 homes/child-occupied facilities. ++EPA+1++

Asbestos AHERA/MAP — accredited Worker, Supervisor, Inspector, Management Planner, Project Designer; annual refreshers; applies to schools & most public/commercial buildings. ++Legal Information Institute++

NCCER — portable, modular Core + craft credentials and journey-level knowledge/performance assessments. ++NCCER+1++

AWI QCP — licensing & audits to certify project compliance for architectural woodwork. ++Architectural Woodwork Institute++

The Credentials & Training Programs DataFrame (above) consolidates this for your agent’s catalog.

3) Craft specifics — millwrights & millworkers (skills + testing)

Millwright (industrial/construction mechanics)

Core skills you should test & observe: precision layout/metrology, shaft alignment (dial & laser), baseplate setting & grouting, rigging/hoisting planning, assembly (bearings/couplings/gearboxes), print reading (P&IDs, GD&T basics), commissioning (vibration baselines).

Use manufacturer tolerances and OSHA Subpart CC for lifts; UBC & NCCER provide curricula/standards you can mirror for competencies. ++ubcmillwrights.org+2ubcmillwrights.org+2++

Millworker (architectural woodwork/casework)

Skills: shop drawings, joinery & casework fabrication, veneer/finish systems, installation tolerances, CNC/tooling, dust & exposure control. Validate against AWI Standards/QCP + OSHA requirements. ++AWI Quality Certification Program+1++

The two skills matrices (Millwright & Millworker) are in the DataFrames I posted to your workspace.

4) What I built for you (today)

Starter repo (FastAPI backend + Streamlit MCQ UI + CI): Download: construction_training_agent_starter.zip

Backend (FastAPI): /api/questions (list, filter by tag), /api/questions/grade (grades submissions).

Frontend (Streamlit): studious theme, filter by tag, radio-button MCQs, “Grade” with metrics.

CI: GitHub Actions workflow runs backend tests.

Samples: OSHA/EPA/millwright/millwork questions seeded.

Roadmap hooks already in requirements for LangChain, LangGraph, Chroma, Pinecone.

Quickstart

5) Product blueprint (so we can scale to any trade)

A. Curriculum/standards registry (data warehouse)

Tables (suggested)

standards(area, code, edition, jurisdiction, citation_url)

credentials(name, issuer, hours, renewal, applies_to)

skills(craft, skill, observable, tolerance, reference)

questions(id, stem, choices[], answer_id, tags[], refs[])

attempts(user_id, question_id, chosen, correct, latency_ms)

rubrics(task_id, criteria, scale, pass_threshold)

Storage: Postgres for OLTP; parquet+DuckDB or S3/Lake for analytics; optional Snowflake/BigQuery later.

B. LLM/RAG layer

Ingest ADA/ICC/NFPA/EPA/OSHA summaries, state boards, AWI/NCCER docs into a Chroma (local) or Pinecone (managed) vector store—chunked with citations & edition metadata.

LangChain pipelines: retrieval-augmented explanations, code lookup (“which IECC section applies?”), and question generation from standards sections.

LangGraph for tool-use choreography (retrieve → draft → cite → validate).

Guardrails: always surface edition + jurisdiction in answers; link to primary source.

C. Testing & skills

Question bank: MCQ, scenario vignettes, image-based safety checks, and performance checklists (e.g., “pump alignment check-off”).

Rubrics: numeric tolerances for millwright tasks; AWI tolerances for millwork installations.

Adaptive testing (IRT-lite): raise/lower difficulty by tag; target minimum competency per credential.

D. Voice & multimodal

ASR (e.g., Whisper) for hands-busy quizzes; TTS for feedback.

Image uploads (scaffold/plank setups, rigging gear) to evaluate OSHA compliance checklists (human-in-the-loop).

E. CI/CD & DevOps

GitHub Actions: lint/test, build containers, deploy to staging.

IaC later (Terraform) + secrets via GitHub OIDC.

Add OpenAPI schema checks and contract tests for the front-end.

F. UI guidelines (studious theme)

Palette: deep blue (primary), green (success), amber (warning).

Controls: Ingest, Process, Map (for network diagrams/learning paths), Assess, Certify.

Surfaced info on every screen: Area of Study, Curriculum, Estimated Completion Time, Standards/Edition, Jurisdiction.

6) What to add next (fast wins)

RAG answers + citations inside the MCQ app (LangChain Retriever → answer → show source).

Role-based views: Apprentice vs. Supervisor vs. Admin (adds 30-hour content, SWPPP tasks, etc.).

Performance module: enter dial indicator readings; auto-flag tolerances out of range.

State packager: pick a state → it composes the right licensing & adopted code editions.

Prediction: simple model from attempts + task rubric scores to estimate time-to-competency and pass probability for a target credential.

If you want, I’ll expand the repo with:

A RAG service (Chroma+LangChain) pre-loaded with briefings for OSHA 1926, RRP, NESHAP/AHERA, IECC, ADA/A117.1, AWI QCP (with edition tags).

A richer millwright practical module that records alignment steps & computes pass/fail against tolerances.

****Download the starter repo (zip)****

****1) Compliance landscape (U.S.) — what “standard” means****

****Model building codes & energy****

****Residential: IRC (one- and two-family). Commercial: IBC. Jurisdictions adopt specific editions; these pull in many referenced standards. ++ICC Digital Codes+1++****

****Electrical (all occupancies): NFPA 70 (NEC) — design/installation benchmark. ++NFPA+1++****

****Energy: IECC (separate residential & commercial provisions). DOE explains scope & applicability. ++ICC Digital Codes+2Energy Codes+2++****

****Accessibility: DOJ’s 2010 ADA Standards (civil rights law) + ICC A117.1 technical standard (often adopted via IBC). (Recent news removed some non-binding DOJ guidance, but ADA law & 2010 Standards remain.) ++AP News+5ADA.gov+5access-board.gov+5++****

****Worker safety (training you’ll test on)****

****OSHA 29 CFR 1926 (construction); OSHA 1910 for shops/fabs. OSHA Outreach 10-hour/30-hour cards are widely required (not “licenses”). ++OSHA+3OSHA+3OSHA+3++****

****Environmental (you’ll want explicit modules & checklists)****

****Lead (pre-1978): EPA RRP — firm cert + certified renovator + lead-safe work practices + records. ++EPA+1++****

****Asbestos: NESHAP 40 CFR 61 Subpart M (survey + 10-working-day notifications + handling) and AHERA/MAP accreditation for specific roles. ++Legal Information Institute+3eCFR+3EPA+3++****

****Stormwater: EPA 2022 CGP (NPDES) — SWPPP, inspections, NOI/NOT; some states run their own CGP. ++EPA+2EPA+2++****

****Specialty quality programs (commercial interiors)****

****AWI Standards & QCP for architectural woodwork/millwork quality certification. ++AWI Quality Certification Program+2Architectural Woodwork Institute+2++****

⚠️ Licensure/contractor cards are state-specific (GC, electrical, mechanical, etc.). Treat state boards/AHJs as sources of truth during onboarding.

****2) Credentials & accreditation (who issues what)****

****OSHA Outreach (10/30) — entry vs. supervisory safety awareness; delivered by authorized trainers. ++OSHA+1++****

****EPA RRP Certified Renovator + Certified Firm — required for paint-disturbing work in pre-1978 homes/child-occupied facilities. ++EPA+1++****

****Asbestos AHERA/MAP — accredited Worker, Supervisor, Inspector, Management Planner, Project Designer; annual refreshers; applies to schools & most public/commercial buildings. ++Legal Information Institute++****

****NCCER — portable, modular Core + craft credentials and journey-level knowledge/performance assessments. ++NCCER+1++****

****Registered Apprenticeship (USDOL/State) — paid OJT + related instruction; nationally portable completion certificate. ++Apprenticeship.gov+1++****

****AWI QCP — licensing & audits to certify project compliance for architectural woodwork. ++Architectural Woodwork Institute++****

****The Credentials & Training Programs DataFrame (above) consolidates this for your agent’s catalog.****

****3) Craft specifics — millwrights & millworkers (skills + testing)****

****Millwright (industrial/construction mechanics)****

****Core skills you should test & observe: precision layout/metrology, shaft alignment (dial & laser), baseplate setting & grouting, rigging/hoisting planning, assembly (bearings/couplings/gearboxes), print reading (P&IDs, GD&T basics), commissioning (vibration baselines).****

****Use manufacturer tolerances and OSHA Subpart CC for lifts; UBC & NCCER provide curricula/standards you can mirror for competencies. ++ubcmillwrights.org+2ubcmillwrights.org+2++****

****Millworker (architectural woodwork/casework)****

****Skills: shop drawings, joinery & casework fabrication, veneer/finish systems, installation tolerances, CNC/tooling, dust & exposure control. Validate against AWI Standards/QCP + OSHA requirements. ++AWI Quality Certification Program+1++****

****The two skills matrices (Millwright & Millworker) are in the DataFrames I posted to your workspace.****

****4) What I built for you (today)****

****Starter repo (FastAPI backend + Streamlit MCQ UI + CI): Download: construction_training_agent_starter.zip****

****Backend (FastAPI): /api/questions (list, filter by tag), /api/questions/grade (grades submissions).****

****Frontend (Streamlit): studious theme, filter by tag, radio-button MCQs, “Grade” with metrics.****

****CI: GitHub Actions workflow runs backend tests.****

****Samples: OSHA/EPA/millwright/millwork questions seeded.****

****Roadmap hooks already in requirements for LangChain, LangGraph, Chroma, Pinecone.****

****Quickstart****

****5) Product blueprint (so we can scale to any trade)****

****A. Curriculum/standards registry (data warehouse)****

****Tables (suggested)****

****standards(area, code, edition, jurisdiction, citation_url)****

****credentials(name, issuer, hours, renewal, applies_to)****

****skills(craft, skill, observable, tolerance, reference)****

****questions(id, stem, choices[], answer_id, tags[], refs[])****

****attempts(user_id, question_id, chosen, correct, latency_ms)****

****rubrics(task_id, criteria, scale, pass_threshold)****

****Storage: Postgres for OLTP; parquet+DuckDB or S3/Lake for analytics; optional Snowflake/BigQuery later.****

****B. LLM/RAG layer****

****Ingest ADA/ICC/NFPA/EPA/OSHA summaries, state boards, AWI/NCCER docs into a Chroma (local) or Pinecone (managed) vector store—chunked with citations & edition metadata.****

****LangChain pipelines: retrieval-augmented explanations, code lookup (“which IECC section applies?”), and question generation from standards sections.****

****LangGraph for tool-use choreography (retrieve → draft → cite → validate).****

****Guardrails: always surface edition + jurisdiction in answers; link to primary source.****

****C. Testing & skills****

****Question bank: MCQ, scenario vignettes, image-based safety checks, and performance checklists (e.g., “pump alignment check-off”).****

****Rubrics: numeric tolerances for millwright tasks; AWI tolerances for millwork installations.****

****Adaptive testing (IRT-lite): raise/lower difficulty by tag; target minimum competency per credential.****

****D. Voice & multimodal****

****ASR (e.g., Whisper) for hands-busy quizzes; TTS for feedback.****

****Image uploads (scaffold/plank setups, rigging gear) to evaluate OSHA compliance checklists (human-in-the-loop).****

****E. CI/CD & DevOps****

****GitHub Actions: lint/test, build containers, deploy to staging.****

****IaC later (Terraform) + secrets via GitHub OIDC.****

****Add OpenAPI schema checks and contract tests for the front-end.****

****F. UI guidelines (studious theme)****

****Palette: deep blue (primary), green (success), amber (warning).****

****Controls: Ingest, Process, Map (for network diagrams/learning paths), Assess, Certify.****

****Surfaced info on every screen: Area of Study, Curriculum, Estimated Completion Time, Standards/Edition, Jurisdiction.****

****6) What to add next (fast wins)****

****RAG answers + citations inside the MCQ app (LangChain Retriever → answer → show source).****

****Role-based views: Apprentice vs. Supervisor vs. Admin (adds 30-hour content, SWPPP tasks, etc.).****

****Performance module: enter dial indicator readings; auto-flag tolerances out of range.****

****State packager: pick a state → it composes the right licensing & adopted code editions.****

****Prediction: simple model from attempts + task rubric scores to estimate time-to-competency and pass probability for a target credential.****

****If you want, I’ll expand the repo with:****

****A RAG service (Chroma+LangChain) pre-loaded with briefings for OSHA 1926, RRP, NESHAP/AHERA, IECC, ADA/A117.1, AWI QCP (with edition tags).****

****A richer millwright practical module that records alignment steps & computes pass/fail against tolerances.****
