Change Orders
Contractors miss legitimate change orders because nobody notices the paper trail.
Walter is the memory that never forgets a scope change — and the part most teams miss: the notice clock. It scans every channel for changes, opens a ChangeEvent the moment one appears, drafts the notice the same day, and builds the priced CO with its time impact.
The problem
What this costs you today — and what Walter does instead.
The pain
Legitimate changes get worked without a paper trail and never get paid.
With Walter
Walter continuously scans drawing revisions, RFI answers, daily logs, and owner emails for changes — every detection becomes a ChangeEvent that can't die silently.
The pain
The notice window expires before pricing is ready, waiving the claim entirely.
With Walter
Notice is drafted the same day from the contract's notice term; it preserves the right before pricing is known and is never held for pricing.
The pain
Time extensions are forgotten and unsigned T&M tickets get disallowed.
With Walter
Every CO carries its critical-path time impact, and Walter chases the superintendent for same-day T&M signatures.
The workflow
How Walter runs it.
- 01
Detect
Continuously scan revisions, RFI handoffs, daily-log keywords, and directive correspondence for scope changes.
- 02
Open ChangeEvent
Every detection becomes a ChangeEvent with evidence links; it closes only as approved, withdrawn, or written off by a human.
- 03
Notice — immediately
Pull the notice term from the contract, instantiate the deadline, and draft the written notice the same day.
- 04
Scope & price
Build the CO narrative, labor/material/equipment buildup, contract markup, and time impact from scheduling.
- 05
Downstream
On prime approval, generate matching sub CO drafts and SOV adjustments for pay applications.
- 06
Unpaid-scope report
Surface every change event not yet resolved, with age, value, notice status, and ball-in-court.
Human in the loop
What stays your call.
- Walter never sends notices, COs, or pricing externally without human approval — it never graduates.
- It never characterizes fault or entitlement beyond contract language; that's PM and legal judgment.
- Pricing uses contract-defined markup and rates only; deviations are flagged, not invented.
What you get
Outputs.
- Change event log
- Same-day notice drafts
- CO packages with buildup and time impact
- Sub CO drafts
- Unpaid-scope report
Hands off to
It doesn't work alone.
Walter's workflows share one construction brain, so a signal in one becomes action in the next — automatically.
RFIs
Route, draft, and chase field questions — never citing a superseded sheet.
Scheduling
Delay detection, lookaheads, and critical-path impact analysis.
Contract Compliance
Notice windows, COI tracking, certified payroll, claims clocks.
Pay Applications
SOV, retainage math, G702/G703, lien waivers before payment.
