AI + Construction Technology Consulting

$90K surfaced.

I build AI systems for construction teams that protect margin, give teams back capacity, and keep judgment with the people accountable for the work.

More than a decade in commercial construction. Four years building production AI systems. Practical judgment about where automation pays off, where it fails, and where accountable decisions must remain human.

The uncommon combination

I did the work before I built the systems.

Most AI consultants must learn how contractors think. Most construction consultants cannot build production AI systems. Ten years of experience informs where I look for margin, value, and risk. That is how I build the right systems.

10+

Years in commercial construction

I have run project management and estimating across Division 26 electrical systems, lighting controls, vendor coordination, scope, and pricing, under the bid-day deadlines that make small inconsistencies expensive.

4

Years building production AI systems

I build and operate the systems myself: agents, retrieval, orchestration, evaluation, local and cloud inference, and the privacy controls required when outputs affect real work.

The advantage is not knowing both worlds. It is knowing what deserves to cross between them.

Evidence before promises.

The portfolio leads with margin protection, validation, and operational capacity. Every case shows where the system stops and accountable judgment begins.

Flagship case study / Margin protection

An automated bid review surfaced $92,482.

The review reconciles internal quotes, manufacturer quotes, bid breakouts, takeoffs, catalog prices, and service rules. It surfaces disagreements with the evidence attached, then leaves correction and approval to the estimator.

Validation / Pricing automation QA

The automation failed its test. So it was not allowed to ship.

An adversarial QA harness showed that an ambiguous fuzzy matching path was wrong in 63 of 66 cases. The path was removed from automatic pricing, while the validated exact match workflow remained in production.

Workflow automation / Quote assembly

A raw vendor export became an import-ready quote in one pass.

It turned a 24-line source into an 88-line structured quote, preserving ERP-critical fields, applying catalog pricing from one shared source, and removing the manual steps where prior transcription errors occurred.

Where I help

Consequential workflows, not generic AI.

The strain shows up the same way in most contracting businesses:

An estimator doing takeoffs on Saturday because the bid is due Tuesday.

An owner still reviewing drawings at ten at night.

A project manager helping bid work instead of running it.

A vendor quote that lands thirty minutes before the deadline.

The engagement starts with one of those moments, not with a technology.

01
Preconstruction intelligence

Protect margin.

Stop pricing errors, scope gaps, and inconsistencies before they become change orders, write-offs, or lost revenue. Bid intake, document review, addenda, pricing QA, quote comparison, and estimate-to-operations handoff.

02
Construction workflow automation

Add capacity without headcount.

Estimators and project managers handle more work because repetitive coordination, reporting, and document processes run reliably, with explicit exception handling and human review.

03
AI strategy and implementation

Build only what pays.

Find the highest-value opportunities, define safe operating boundaries, prototype quickly, and walk away from automation that will not pay for itself.

Technical depth

Construction judgment, backed by production systems.

These cases show the production discipline behind the construction work.

System 01 / Orchestration

Concurrent multi-agent execution

A dependency-aware orchestrator produced 2.3x realized end-to-end throughput on decomposable work, with fresh contexts and an independent verify-and-resynthesize gate.

System 02 / Sovereignty

Code-enforced local and cloud routing

A fail-to-local router and deterministic redaction gate were validated across 1,821 transcripts and 19,124 events with zero confirmed leaks.

System 03 / Adversarial review

Case studies from sensitive sources

A four-stage content pipeline used a separate adversarial reviewer to catch four confidentiality leaks across five drafts before human approval.

Working method

Observe the work before automating it.

A practical sequence for separating true leverage from impressive technology that creates another system to manage.

Step 01

Observe

Map the real workflow, documents, decisions, exceptions, handoffs, and failure points.

Step 02

Find leverage

Estimate where errors, rework, delay, or administrative load create the greatest commercial cost.

Step 03

Build the smallest useful system

Prototype around one consequential workflow instead of attempting a company-wide transformation.

Step 04

Prove it

Measure outcomes, preserve human review, document the process, and expand only when the evidence supports it.

Trust model

Built for confidential and consequential work.

Construction data is not portfolio material. Responsible implementation begins with protecting the business, the people, and the source documents.

01
Anonymized public workNo job names, clients, part numbers, manufacturers, or real project pricing in published examples.
02
Minimum necessary accessUse only the information required to solve the defined problem.
03
Traceable evidenceImportant outputs point back to their source inputs, assumptions, and failure conditions.
04
Explicit human approvalAutomation assists accountable decisions. It does not conceal or silently replace them.
05
Honest tool boundariesTechnology choices follow the workflow. Expertise is never invented to fit a sales call.

Start with the workflow

Where is your construction process losing margin or capacity?

Bring one difficult workflow, overloaded process, or recurring document problem. We will determine whether the right answer is process improvement, automation, a focused AI system, or no technology at all.
