Stop the schedule slip. Ship every project on time.
Relay is construction schedule management built for the people running the job — general contractors, project managers, and the subs reporting from the field. One shared timeline. Every change, every delay, every approval in real time.
Cancel anytime · Foremen & subs always free
Construction delays don’t just slow projects down.
They quietly bleed the business dry.
For most small and mid-size contractors, the real cost of a delay isn’t the missed deadline — it’s the downstream damage. Stacked trades, escalating material prices, financing carry, and three follow-up projects that start late because this one ran long.

Relay is built to attack the root cause: bad coordination between the GC, the PMs, and the crew. One shared schedule. One inbox. One approval that ripples to every downstream activity — and every word of it captured on the project, ready to export the moment you need the receipts.
Construction schedules don’t live in spreadsheets.
They live in your head — and everyone else’s phone.
Most GCs and PMs run their projects on a Frankenstein of texts, calls, and a Gantt PDF that's a week out of date. Subs follow verbal updates. By the time a delay reaches the right person, the domino has already fallen.
Coordination by phone tag
Schedule changes come in by text, voicemail, group chat — three places at once. PMs hear it first, GCs hear it last, and nothing is the source of truth.
Delays you can’t see coming
One trade slips a week. You re-calculate every downstream activity by hand on a Gantt PDF that’s already a week out of date — and stacked trades cost up to 30% in lost productivity.
Crews showing up cold
Subs and foremen don’t know when they’re up, what changed, or who they’re following. Standups burn 20 minutes answering the same questions every Monday.
From phone tag to one source of truth — in four steps.
Build your schedule
Add a project, drop in activities by trade, set your dates. Link predecessors with a drag if you want them — Relay works either way.
Invite your team
Send each PM, sub, or foreman a personalized link. No login, no app to download.
The field reports back
When weather hits, material slips, or a trade finishes early, the crew submits a date change from their phone in 30 seconds.
Approve and cascade
You approve. Relay shifts every downstream activity automatically and notifies everyone affected. Done.
Three roles, one source of truth.
Every project runs on a chain of command — a GC at the top, PMs delegating to crews, foremen on the ground. Relay gives each role exactly what they need to stay on time, without drowning them in information they don't need to see.
General Contractor
Owns the project, sets the schedule, runs the show.
Builds the master timeline. Invites subs and PMs in seconds. Approves changes, sees the cascade ripple out.
- ✓Create projects + activities with one tool, no spreadsheets
- ✓One-tap approvals push date changes through the schedule
- ✓Sees who's on time, who's slipping, who needs a nudge
Project Manager
Takes a piece of the GC's schedule and runs a crew underneath it.
Receives projects from any GC. Breaks parent activities into sub-tasks for their own foremen. Handles their crew's requests without ever bothering the GC.
- ✓Receive work from one or many GCs in a single inbox
- ✓Create your own projects too — full GC capabilities included
- ✓Delegate sub-activities to foremen, approve their changes
Foreman / Subcontractor
The crew doing the actual work, reporting from the field.
Gets a personalized link. Sees only what they're assigned. Submits schedule changes or completion confirmations from their phone — no login, no app to download.
- ✓Sign in with an email code, never a password
- ✓See only your assigned activity — no schedule noise
- ✓Request date changes from your phone in 30 seconds
A GC drops an activity on a PM. The PM splits it into sub-tasks and hands them to their foremen. Weather changes the plan? A foreman submits a date change — only the PM sees it, approves it, and the GC's schedule stays clean. Need to push a parent date? The PM kicks the change up to the GC, who approves it once, and Relay cascades every downstream activity. No phone tag. No texts lost in a group chat. Everyone sees exactly the slice of the project they need to see.
Every schedule change in one place.
Subs and foremen request shifts and completions from their phone. GCs and PMs see everything in a unified Inbox — one-click approve, deny, and a cascade preview so you know exactly what gets bumped before you commit.
- Schedule changes and completion requests in one feed
- Cascade preview shows every downstream activity that shifts
- Approve with one click — Relay re-calculates dates automatically
- Confirm with or without cascading, depending on the situation
- Quick filters by project, status, and urgency
Crews see exactly where they fit.
Each sub or foreman gets a personalized link — no login, no app to download. They see their assigned activity in the context of the full project sequence, with the work before and after them clearly labeled.
- Personalized link per crew member, no account needed
- Dependency timeline shows what precedes and follows them
- Two-button workflow: mark complete or suggest a change
- Past requests with your reply — full transparency
Change one date. Relay moves the rest.
Link predecessors and successors with a single drag on the Gantt — Relay captures the lag between them automatically. No links yet? It still works: Relay infers successors from start dates, so day one needs zero setup. Either way, every approved change shows you exactly what shifts before you commit.
- Drag-to-link Finish-to-Start dependencies, lag captured automatically
- No links? Relay infers successors from dates — zero setup required
- Cascade preview shows every downstream shift before you commit
- Hold out fixed dates — inspections and deliveries can sit out the ripple
- Critical-path highlighting on the Gantt
Cascade preview
Approving this shifts Plumbing Rough-In and all activities starting on or after Apr 8.
Every change, every comment, on the record.
The job's whole story lives inside the project: who moved a date, when a sub committed, what got approved, what got pushed back. Direct comment threads on every activity replace the text chains that walk out the door when an employee does. When the carrier or owner asks why a job ran long, the answer is a PDF — not an argument.
- Activity-level comment threads — direct sub ↔ PM ↔ GC, scoped to the work
- Every date change, approval, sign-off, and completion captured automatically
- Per-activity completion PDFs emailed to the assigned crew the moment work wraps
- One-click project history PDF — carrier-ready, dispute-ready, ownership-change-ready
- Sub-activity opacity preserved — a PM's foreman delegation stays private
Priced for the people running the job.
GCs and PMs pay. Foremen and subs are always free, on every plan. One license per contractor. Active projects only — archived projects don't count toward your limit.
For context: the daily overhead of a mid-size build sitting in limbo runs $1,500–$2,500. Starter pays for itself the first time Relay catches a slip before it cascades.
