Strengthening GMP Performance Through Early Steel Authority
Better scope. Better bids. Fewer surprises.
The Challenge
In CMAR delivery, structural steel is often one of the largest unknowns at GMP.
Incomplete design and unresolved constructability issues force estimators and fabricators to price uncertainty — increasing contingencies and reducing bid quality.
When steel decisions remain fragmented before buyout, risk is transferred forward instead of removed.
The ISPA™ Advantage
ISPA™ — Integrated Steel Planning Authority — consolidates early steel decision-making into one governed framework.
Through Accelerated Steel Procurement (a.s.p.™), Greenbrook integrates detailing, connection design, fabrication insight, and erection planning during design development — before GMP is locked.
Rather than relying on multiple early trade inputs, ISPA™ provides a single authority governing steel scope prior to procurement.
How a.s.p.™ Supports CMAR Teams
Improved Bid Quality
Defined scope reduces contingencies
Reduced Exposure
Fewer downstream change orders
Stronger GMP Confidence
Greater pricing clarity
Owner Trust
Predictable fabrication starts
Timeline Impact
Traditional steel coordination continues after GMP, creating exposure during detailing and fabrication.
With a.s.p.™, steel planning runs in parallel with design — allowing scope to be defined before GMP and stabilizing procurement.
The Result
Earlier clarity. Lower exposure. More reliable pricing. Stronger owner confidence.
When to Engage
Greatest value when engaged during SD, DD, or prior to GMP finalization.
