# 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 into the estimate as defensible line items instead of a lump sum. - [Contracting](https://www.ediphi.com/contracting): Generate bid packages from the estimate with measurable scope coverage, level subcontractor bids line by line with holds and allowances, and track buyout in a live schedule of values. - [Last Mile](https://www.ediphi.com/last-mile): An Excel add-in that binds workbook cells to live estimate values, so owner bid forms, executive summaries and dashboards refresh on every revision instead of being retyped. Runs on Mac, PC, desktop Excel and Excel on the web. - [Value Management](https://www.ediphi.com/target-value-management): Design-phase milestones, a budget-to-GMP cost trendline, one-click variance reporting between any two estimates, and a priced decision log for alternates and VE options that flow into the base bid on approval. - [Integrations](https://www.ediphi.com/integration): Connections to Excel via Last Mile, Togal.AI for AI quantity takeoff, On-Screen Takeoff .OST imports, Bridgit for workforce planning, and CRM for pipeline data. ## Comparisons - [Ediphi vs DESTINI Estimator](https://www.ediphi.com/ediphi-vs-destini-estimator): Cloud-native platform compared with DESTINI Estimator on deployment, collaboration and the conceptual-to-detailed workflow. - [Ediphi vs Trimble WinEst](https://www.ediphi.com/ediphi-vs-trimble-winest): How a browser-based estimating platform differs from WinEst's desktop and hosted-desktop model. - [Ediphi vs Sage Timberline Estimating](https://www.ediphi.com/ediphi-vs-sage-timberline-estimating): Modern cloud estimating compared with Sage Timberline (Sage Estimating) on cost databases, collaboration and reporting. - [Ediphi vs Autodesk ProEst](https://www.ediphi.com/ediphi-vs-autodesk-proest): Comparison of Ediphi and Autodesk ProEst for preconstruction estimating teams. ## Customer stories - [Suffolk](https://www.ediphi.com/customer-stories/suffolk): Nationwide rollout reported to increase revenue per estimator by $20M with 1,900% ROI. - [Stevens Construction](https://www.ediphi.com/customer-stories/stevens-construction): How Stevens Construction saves time and wins more work with Ediphi. - [Wright-Ryan Construction](https://www.ediphi.com/customer-stories/wright-ryan-construction): Roughly 7 hours saved per estimate. - [Landry/French](https://www.ediphi.com/customer-stories/landry-french-customer-story): Scaling a preconstruction department without adding headcount. - [How Suffolk built a seamless preconstruction workflow with Ediphi x Bridgit](https://www.ediphi.com/blog/how-suffolk-built-a-seamless-preconstruction-workflow-with-ediphi-x-bridgit): Estimate-to-workforce-plan integration; 50% shorter staffing cycles and 75% less coordination staff. - [DPR Construction selects Ediphi as its global estimating and preconstruction platform](https://www.ediphi.com/blog/successful-pilot-program-leads-to-nationwide-deployment): Pilot to enterprise-wide deployment. ## Solutions - [Joint Ventures](https://www.ediphi.com/joint-ventures): Running preconstruction across JV partners on large, high-stakes capital projects with one shared cost model. - [Education](https://www.ediphi.com/education): Ediphi for construction management programs and the classroom. - [Ediphi Academy](https://www.ediphi.com/blog/ediphi-academy-launch-announcement): Certification platform for modern preconstruction. ## Documentation and support - [Ediphi Help Center](https://help.ediphi.com/): Product documentation, how-to articles and video walkthroughs. - [Help Center — Estimates](https://help.ediphi.com/category/7-estimates): Building and managing estimates, line items, area sheets, units, markups and reporting. - [Help Center — Contracting](https://help.ediphi.com/category/11-contracting): Bid packages, scope sheets, bid leveling, buy sheets and the schedule of values. - [Help Center — GCs & GRs](https://help.ediphi.com/category/4-gcgr): Staffing plans, crews, durations and general conditions setup. - [Help Center — General](https://help.ediphi.com/category/10-general): Navigation, projects, permissions and everyday platform use. - [Help Center — Admin](https://help.ediphi.com/category/29-how-to-videos): User management, project permissions and product administration. ## Reference - [Construction & Preconstruction Glossary](https://www.ediphi.com/glossary): 118 defined terms — bid leveling, GMP, CSI MasterFormat, escalation, contingency, CMAR, design-build, IPD, general conditions and more.
