AI Agents for
General Contractors
Your bid pipeline has 14 open quotes. Three subs haven't confirmed for Monday. Two projects have unresolved change orders sitting in someone's inbox. Agent Harbor deploys an AI agent fleet that tracks all of it 24/7 — so nothing falls through the cracks on a job site or off one.
General Contractors Lose Money to Coordination Gaps, Not Bad Work
The margin on a GC job is won or lost in coordination — bids that go cold, subs that go dark, change orders that never get signed.
$4,200
Average value of an untracked change order
Change orders that don't get signed — or get signed late — directly erode margin. On a $200,000 project, even 2% in unsigned change orders represents $4,000 of work done for free.
3 weeks
Average bid staleness before follow-up
Most GCs deliver a bid and follow up once. After that, silence. A structured bid follow-up sequence keeps your proposal in front of the decision-maker through the full approval process.
Sub gaps
Most costly day on a job site
A subcontractor who doesn't show costs $2,000–$8,000 in downtime — idle crews, delayed inspections, cascading schedule impacts. Confirmation protocols and 48-hour alerts prevent most of them.

Bid Pipeline Management That Never Drops a Proposal
A general contractor's revenue is built on bids — and most bids die from silence, not rejection. You deliver a proposal, follow up once, and move on to the next job. The decision-maker is still circling, but you're not there when they're ready.
Your Quote agent runs a structured follow-up sequence on every delivered bid, calibrated to the typical approval timeline for each job type. Commercial bids get longer sequences. Residential bids move faster. High-value proposals get flagged for personal attention.
At the Growth tier, the Sub agent manages your subcontractor confirmation protocol — 48-hour and 24-hour confirmations before every scheduled day, with automatic escalation if a sub goes dark.
Day 3. Quote follow-up: 'Following up on the commercial build-out estimate — wanted to make sure you had everything you needed to move this forward with your ownership team.'
48h alert. Sub: 'Confirmation needed from Martinez Electrical for Thursday — no response in 24 hours. Escalating to backup sub per protocol.' Gap prevented before it costs you the day.
Change order. Change: 'CO #7 for the Harbor View project has been outstanding 6 days without signature — total value $3,840. Flagged for owner follow-up today.'
CO registry. Change: 'Active change orders across 8 projects: $24,600 total outstanding. 3 orders are 5+ days unsigned — draft follow-ups ready for review.'
Milestone alert. Milestone: 'Riverside Commercial is tracking 4 days behind on rough framing — inspection window at risk. Adjusted schedule draft ready for PM review.'
Weekly digest. Digest: 'Week of March 3: 3 bids delivered, 1 bid won ($142k), 2 change orders signed ($8,200), 1 project on schedule, 1 tracking 4 days behind.'
Change Order and Project Milestone Tracking That Protects Margin
Change orders are where GC margin is won or lost. The work gets done regardless — the question is whether you get paid for it. Most change orders stall because no one is tracking them systematically.
Your Change agent maintains a live registry of every open change order across all active projects. It flags unsigned orders daily, drafts follow-up messages when they go stale, and reports the total outstanding value every week so you know exactly where your margin stands.
The Milestone agent tracks project schedules against planned completion dates — alerting when a project is falling behind in time for you to act, not after the delay has already cost you.
