Bid · Build · Trades — one login

The commercial construction platform for the whole project.

GridLine runs preconstruction, field execution, and trade-partner bidding in a single system — AI-assisted takeoff, scheduling, plans, RFIs, submittals, budgets, and the daily field record, all connected.

Built by commercial builders, for how the work actually runs.

One platform, three workspaces

Everything a commercial project needs — nothing bolted on

GridLine is organized the way commercial work actually moves: estimate it, build it, and coordinate the trades. Every tool below is part of the system.

What makes it different

Capabilities you can actually trust on a live job

Auditable AI takeoff

AI extracts geometry and quantities from plan PDFs and shows every measurement as an overlay you can inspect. Nothing is trusted until a human approves it.

A real plans viewer

Pan, zoom, mark up, and align multi-sheet overlays and revisions — with sharp rendering on desktop, tablet, and phone.

Scheduling that reacts

Drag-and-drop Gantt logic, critical-path calculation, and baselines — updated from what the field actually reported that day.

Built for the field

Dedicated mobile screens for daily reports, site photos, observations, and progress updates so the job site stays in sync with the office.

Standardized reports & exports

Every register and report shares one branded PDF/CSV format — consistent filenames, dates, and project numbers across the whole system.

Light & dark, everywhere

A cohesive interface with full dark mode, per-seat licensing, and role-based access — the same system whether you're a PM, a super, or an admin.

Pricing

Simple per-seat pricing

One price, every tool. No feature tiers, no upsells to unlock the parts you need.
