How Holder Construction closed a $34M healthcare build 27 days ahead of schedule.

A regional hospital expansion in central Texas — six disconnected spreadsheets, RFIs lost between email and Procore, change orders surfacing too late to bill, and a project manager's inbox overflowing at 11 PM.

Before Stroyby — six tools, no source of truth

Drawings lived in Procore. RFIs in email threads. Daily logs in a separate field app. Subcontractor payouts in Excel. Change orders in a project manager's notebook. Every Monday the team reconciled the same gaps on a whiteboard.

The switch — one workspace for the whole job

Holder's project executive migrated 14 months of project data into Stroyby over a 9-day onboarding. The field crew moved from a legacy app to Stroyby's mobile workspace on a Tuesday. The AI field-log translator was enabled for the Spanish-speaking trades on day one.

The new rhythm — redlines at 7:14, on-site by 7:30

A live-linked drawing markup at 7:14 AM was on the foreman's phone before the 7:30 toolbox talk. Daily logs auto-routed to the project manager's review queue. RFIs closed in a single thread instead of disappearing into inbox folders.

The outcome — 27 days early, 3.4× change-order revenue

The hospital expansion topped out 27 days ahead of the contract schedule. Change-order revenue surfaced 3.4× the prior build on legacy tools. The project closed out in 4.7 months — the same payback window the Forrester TEI study averages across the customer base.

“The day we stopped reconciling spreadsheets on a Monday morning was the day the project sped up. The foreman had the latest redline before his boots hit the gravel.”
