Decisions poured in concrete.
In construction, a decision is a thing you physically cannot take back. Wavn argues the bid, the sub, the change order, and the sequence with three minds, and keeps the record that claims and disputes are won with.
Construction decisions harden, literally. The bid margin, the subcontractor you trust, the change order you accept, the sequencing call that puts one trade ahead of another, each becomes fact on the ground within weeks. And when the dispute comes, two years later, the side with the written reasoning wins. Wavn argues those calls while they're still reversible, and keeps a dated record of why each was made, which in this industry isn't philosophy, it's claims defense.
Where the cost of getting it wrong is real.
Bid it, and at what margin
Pricing a job aggressively enough to win and honestly enough to survive winning it.
The sub you can actually rely on
Choosing between the cheap bid, the known quantity, and the one with the best paper, when the wrong choice cascades through the schedule.
The change order fight
Deciding which changes to absorb, which to price, and which to escalate, with the client relationship and the margin both in play.
Sequence and schedule risk
Ordering the trades and the phases when every path has a bottleneck and weather votes last.
Your workflow, with the thinking kept.
The bid, attacked before submission
The minds argue the estimate the way the project will: labor availability, material lead times, the allowance that's really a guess.
Where the risk actually sits
Converge maps which schedule and cost assumptions everyone agrees on, and which one the whole bid quietly rests on.
A dated record, kept
Lock the call on the sub, the change order, the sequence, with reasoning and dissent dated. When the claim comes, the record exists.
The owner-ready package
The decision generates the change-order justification, the schedule narrative, the one-pager for the owner's meeting.
Milestones that brief you
Inspection dates, sub mobilizations, and decision deadlines land on the Schedule, with briefs before each and debriefs after.

This is The change order, stage by stage. Click any step on the line and the screen follows.
Three minds take positions and argue them properly. Converge maps the real shape.
Deciding is half the work. Wavn walks the rest.
A thought caught on your phone becomes a project. Three minds argue it, the call is locked with its dissent, and then the road opens: the accounts you'll need in plain words, a spec in one click, documents and decks and spreadsheets generated from the decision, Claude connected to build the real thing, and the launch on a Schedule that briefs you before every date. The Journey report can replay all of it, months later, when someone asks why.
A mid-size general contractor
Construction · Commercial work, US Southeast
A GC is deciding whether to accept a major change order at cost to protect a client relationship, or price it fully and risk the relationship. The PM and the owner of the firm disagree, and whatever is decided will surface again in the closeout negotiation a year away.
- 01The change order, the contract language, and both positions go on a canvas.
- 02The minds argue absorb vs. price-it: Converge shows the 'relationship risk' claim is unsupported, while the precedent risk of free work is real.
- 03The firm locks a decision: price at documented cost plus reduced margin, with the reasoning and the client history attached.
- 04The justification package generates from the decision; the closeout negotiation date lands on the Schedule with the full record armed.
The client accepted the priced change order without drama, the precedent held on the next three, and at closeout the GC negotiated from a dated record of every change decision while the owner's rep worked from memory.
This scenario is illustrative, a composite of how construction & engineering teams work, not a named client. Wavn is invite-only and we don't publish customer names without permission.
Wavn doesn't estimate your jobs or manage your site. It makes sure the decisions that get poured in concrete were argued while they were still liquid, and keeps the record that wins the argument afterward.
