Cornerstone PROJECT CONTROLS
Building Envelope Project Controls

Project controls built for the building envelope trades.

The gap between what gets sold and what gets executed is where project risk lives. Cornerstone builds the continuity that closes it, from bidding to closeout.

The Bid Enhancement Difference

The contractor who arrives with a CPM schedule, a procurement schedule, a financial forecast, and clearly defined scope documents is not bidding. They are negotiating.

Most contractors walk into the interview with a price. You walk in with a plan. Not as a candidate — as a team ready to join a team. Cornerstone builds the documents that make that case before you say a word.

One engagement. Built around how facade projects actually run.

The system runs from bidding through closeout. Here is what that looks like.

Pre-Award Engagement
Bidding phase through Notice to Proceed

You enter the negotiation prepared — a CPM schedule, a procurement schedule, a financial forecast, and clearly defined scope documents that tell the story before anyone asks a question.

At NTP the framework activates. The deliverable log built from your bid documents becomes the working record. Data-based submissions are prepared from manufacturer sources and held ready for the first submission cycle. No rebuild, no cold start.

Active Maintenance
Notice to Proceed through Closeout

The system does not run itself. Every week Cornerstone prepares the look-ahead your PM walks into the site meeting with — structured talking points built from the updated schedule, organized around what is due, what is overdue, and what the CM needs to act on.

Critical project progress is logged the week it happens, not reconstructed months later when the history is buried in emails and project management platforms you may no longer have access to. Every month ownership receives a two-page report card showing where the project actually stands. The record that protects you at closeout is built one week at a time, from the first look-ahead to the last unit signed off.

Post-Award Engagement
Engagement at Award or NTP

No pre-award framework in place. No problem. The full system is built from your executed contract documents, at working level, from day one.

The value is in what it prevents.

Cornerstone engages at the bidding phase or at award. Earlier engagement means the framework is built before the pressure starts.

"The way you do one thing is the way you do everything."
The Cornerstone Standard
"The PM inherits the commitments made at the closing table. Cornerstone ensures everyone is on the same page."
The Handoff Problem

Built from both sides of the table.

Thirty years of dual-seat experience, facade subcontractor and construction manager. That background is not a credential. It is the reason this system works.

Construction documents review on site
As the Subcontractor
Every deliverable deadline, every fabrication decision, every delay that became a cost the contractor absorbed. Built by someone who has been in that position.
As the Construction Manager
Every bid review, every schedule dispute, every claim that could not be supported. Cornerstone knows what the CM is looking for because Cornerstone has been the CM.
One Contractor Per Project
The engagement is exclusive. The record Cornerstone builds belongs to that contractor and no one else.
The Contractor Focuses on the Work
Cornerstone handles the documentation so the contractor never has to choose between execution and the record.
