Civil design. Software builder. Bay Area.

I design civil infrastructure and build software for AEC.

Background

In AEC since 2016 — Nibbi Bros, Westland Group, BKF Engineers, now Qualus.

Currently

Building software for architecture, engineering, surveying, and construction. RedlineIQ is live; more on GitHub.

Production AI tools for engineering work.

All built from problems I run into on jobsites, in CAD, and in agency review.

RedlineIQ

Upload a redlined PDF. The system reads every annotation and returns a structured drafter checklist — classified, cross-referenced to sheets, and confidence-scored.

Problem

Drafters lose hours each day decoding PM redlines before they touch Civil 3D. I did this job for two years.

Approach

A source-type router parses digital PDFs losslessly and falls back to a vision model for scanned sheets. An eval harness with labeled golden sets and a versioned prompt registry keeps accuracy honest.

Proposal Editor

AI editing for designed AEC proposal PDFs — describe a change in plain language, review a word-level diff, export to Word with native tracked changes.

Benefits Rep Copilot

Grounded RAG QA for benefits plan documents — client-filtered retrieval, verified citations, and a CI-gated eval that holds refusal accuracy as a hard floor.

Leads Toolkit

Two MCP servers — Google Places search and opportunity scoring — that turn hours of per-firm prospect research into one agent workflow.

02/03 About

A civil engineer who ships software.

Nick Furr — Bay Area

I built physical infrastructure before I built digital. At Nibbi Bros I ran takeoffs, subcontractor coordination, and field problem-solving on the SFO Long-Term Parking Garage and an LIHTC housing project in San Francisco.

At Westland Group I automated SoCal Gas as-builts in VBA — my first production code. Two years at BKF Engineers as Civil 3D Designer on Treasure Island, Adrian Court in Burlingame, and 2201 Valley St in Oakland. In 2021 I started building software for the industry. Today I do civil design at Qualus, and build software independently.

2016 Nibbi Bros — Project Engineer, summers 2016 & 2017. SFO garage, LIHTC housing.

2018 Westland Group — SoCal Gas as-builts. First production VBA.

2019 Cal Poly Pomona — B.S. Civil Engineering. EIT.

2019 BKF Engineers — Design Engineer, Civil 3D designer through 2021.

2021 → Independent — full-stack development. Software and workflow solutions for AEC.

2026 → Qualus — Civil Engineer. Design and power systems.

Now RedlineIQ live. Building software for plan review, proposals, and field workflows.
