Preconstruction schedules
in minutes, not weeks.

Pennie turns a building program into a defensible, owner-ready CPM schedule — instantly. Test scenarios, track versions, and hand your team a schedule they can actually build to. Scheduling is where Pennie starts, not where it stops.

1

Describe the building

Stories, floor plate, structure, program. The things you already know at day one — no activity-by-activity data entry.

2

Pennie builds the CPM

A full critical-path network with real construction logic: releases, field measures, phase gates, close-out ties. Driving path included.

3

Refine, version, share

What-if scenarios in seconds, automatic version checkpoints, and an owner-ready Excel export when it's time to circulate.

Built like a scheduler thinks

A real CPM engine

Forward/backward pass, float, and a driving-path trace — computed live in your browser, not a drawing of a schedule.

What-if in seconds

Change the plate, the stories, the structure — the network rebuilds and shows you what moved and why.

Versions & checkpoints

Every meaningful change checkpoints automatically. Compare, restore, and keep the narrative straight.

Owner-ready exports

A clean Excel schedule with your company name and logo on it, ready for the deck or the lender.

Teams & roles

Organizations with admin, editor, and viewer roles. Invite by email link; viewers see everything and change nothing.

Private by design

Your projects live in your workspace. No trackers, no third-party scripts, no selling data — see the privacy policy.

Early access is invite-only

We onboard a few teams at a time. Leave your email and we'll reach out.
