Project Setup

Enter your project once. Every tool reads it.

The project record — location, building type, flood zone, zoning, BIM status, and goals — populates every downstream tool automatically. No re-entry, no inconsistency, no tool that doesn't know what you're working on.

Auto-populates climate zone, EIA electricity rate, and regional cost multiplier from ZIP or address

Pre-Planning Analysis

The pro forma before the schematic.

Site envelope, IBC code matrix, and development pro forma — modeled in real time before a line is drawn. This is where an architect's influence on project economics is highest. ArchDatum puts the tools in your hands at exactly that moment.

Certification Library

Know what you're recommending before you recommend it.

LEED v5, FORTIFIED, Phius, ENERGY STAR, and the Living Building Challenge — compared side-by-side on cost, timeline, third-party requirements, and liability implications. Including contract structure for each, because a certification recommendation without a scope rider is an incomplete recommendation.

AIA contract document guidance specific to each certification path

For Architects

The pre-design tools that make you the most useful person in the room.

Architects shape owner decisions before they become expensive. ArchDatum gives you the financial language to do that — pro formas, ROI models, insurance analysis, and certification guidance — all reading from one project record you entered once.

Model the developer pro forma and site envelope before schematic design — when your influence on project economics is highest
Run ROI on certification paths and connect them to AIA contract scope riders automatically

For Owners

Know the numbers before the schematic design meeting.

The most expensive decisions in a capital project get made before design begins. ArchDatum gives your architect the tools to model those decisions — and the language to explain them — so you walk into schematic design with your pro forma, your risk profile, and your certification strategy already in hand.

Developer spread and asset value modeled against actual RSMeans construction costs — not rough estimates
Flood zone, wind exposure, and climate overlay risks quantified before permit — not after
Certification paths compared by cost, timeline, and 25-year ROI so you choose the right one from the start
