# Ediphi

> Ediphi is a cloud-native estimating and preconstruction platform for general contractors, construction managers, owners and cost consultants. A single estimate file carries a project from conceptual budget through GMP and buyout, priced from the contractor's own historical cost data, edited by multiple estimators at once in any browser on Mac or PC.

Ediphi replaces desktop estimating software (DESTINI Estimator, Trimble WinEst, Sage Timberline Estimating, Autodesk ProEst) and the spreadsheets that surround it. Because conceptual estimating, detailed estimating, cost modeling, the unit price catalog, general conditions, buyout and value management all run on the same data, there is no rebuild or re-keying between phases.

Key facts:

- Modules: Estimating, Cost Modeling, Unit Price Catalog, GCs & GRs, Contracting, Last Mile (Excel add-in), Value Management.
- Delivery: browser-based SaaS. No Citrix, hosted desktop or VPN; typically deployed in a day.
- Users: preconstruction and estimating teams at general contractors and CM firms, joint ventures, owners and cost consultants.
- Company: founded by Dustin DeVan (CEO & Co-Founder, previously founder of BuildingConnected) and Mike Navarro. Emerged from stealth with $6.5M from Suffolk Technologies, followed by a $12M Series A led by Norwest Venture Partners.
- Customers include DPR Construction, Suffolk, Hensel Phelps, Landry/French, Stevens Construction, Wright-Ryan Construction and Terra Construction.
- Reported results: Suffolk reported a $20M increase in revenue per estimator and 1,900% ROI; Wright-Ryan reports saving roughly 7 hours per estimate.
- Terminology used across this site: preconstruction, precon, conceptual estimating, parametric estimating, cost modeling, benchmarking, unit price catalog (UPC), general conditions (GCs), general requirements (GRs), bid leveling, buyout, schedule of values (SOV), guaranteed maximum price (GMP), target value design, value engineering (VE).

## Platform

- [Estimating](https://www.ediphi.com/estimating): Conceptual and detailed estimating in one cloud file — use groups, area sheets, unit mix and multi-trade systems, with dimension-driven formulas that refactor the estimate when the design changes.
- [Cost Modeling](https://www.ediphi.com/cost-modeling): Turn completed estimates into a live benchmark database — filter to genuinely comparable projects, apply time and location escalation, report custom denominators ($/key, $/bed, $/kW, $/stall) and carry a model into a live estimate.
- [Unit Price Catalog](https://www.ediphi.com/unit-price-catalog): A company-wide cloud cost database fed automatically by real project costs, with region-specific pricing, per-estimator MyUPC sandboxes and administrator approval into the company standard.
- [GCs & GRs](https://www.ediphi.com/general-conditions-requirements): Build staffing plans, crews and temporary facilities against the project schedule, then push general conditions and general requirements costs
