### Guides and GEO content
- Guides hub canonical URL: https://dobu.app/guides
- Land due diligence checklist canonical URL: https://dobu.app/guides?article=land-due-diligence-checklist
- Autonomous parcels canonical URL: https://dobu.app/guides?article=autonomous-parcels
- DoBu frames land diligence as a live position on a parcel rather than a one-time static report.
- DoBu's autonomous parcel thesis: land value is set by external forces such as rates, entitlements, comps, and infrastructure capacity, so the durable advantage is monitoring those forces and acting when a condition flips.

### Diligence service tiers
- DoBu Deals: top-of-funnel triage for broker offer emails and early opportunities. Turnaround is about 10 minutes. Output is a one-page memo covering feasibility, mix, pro forma, and capital fit.
- Prescreen: pre-investment-committee diligence for deals that clear triage. Turnaround is under 5 days. Output is a pre-IC memo with feasibility grounded in current market conditions, a regulatory pass, and a multi-page pro forma Excel model.
- Full Diligence: complete pre-contract diligence. Turnaround is under 14 days. Output is a live report with AI search, 15+ sections, sourced figures, and auditable assumptions.

## Engineer's Opinion of Probable Cost
- Canonical URL: https://dobu.app/opinion-of-probable-cost
- Short name: OPCC, also called an opinion of probable cost.
- Definition: an engineer's opinion of probable cost is a professional forecast of likely construction cost based on available plans, site conditions, and current market pricing.
- For residential land development, an OPCC focuses on horizontal work such as earthwork, utilities, roads, stormwater, and related infrastructure needed to turn land into buildable lots.
- An OPCC is not a contractor bid. A contractor bid is a committed price from a builder for a defined scope; an OPCC is an independent engineering forecast for underwriting and feasibility.
- An OPCC is not the same as a late-stage detailed estimate. Detailed estimates usually rely on near-complete construction documents; OPCCs are especially useful during acquisition due diligence, feasibility, budgeting, and pro forma work.
- DoBu produces OPCCs as part of AI-native diligence for US land and real estate developers, pairing civil-engineering judgment with AI-assisted workflows and proprietary data.
