The Four Pillars of Commercial Construction
Our reference library answers the four questions every commercial real estate developer, owner, and operator asks before a project breaks ground: what it costs, what to spec, how to run it, and how to fund it.
Construction Costs
National cost benchmarks across 30+ commercial building types: cold storage, QSR, medical, data center, cannabis, self-storage, with regional variation across all 50 states.
What does it costBuilding Systems
The owner’s spec guide: IMP envelope chemistry, PEMB structural systems, MEP coordination, roofing assemblies, flooring systems, and the manufacturer relationships that drive lead time and cost.
How to spec itProcess & Delivery
The project playbook: design-build vs design-bid-build, GMP vs cost-plus, owner’s rep engagement, the 7-phase project lifecycle, and the change-management frameworks that keep schedule and budget intact.
How to run itFinance & Advisory
The owner’s underwriting playbook: capital stack, construction loans, NOI and yield-on-cost, cost segregation, bonus depreciation, 179D, Opportunity Zones, and the advisory roles that protect equity returns.
