Does this replace a civil engineer?

No. The output guides early siting decisions; formal drainage and grading plans require a civil engineer.

How accurate is the topography read?

USGS 3DEP elevation, computed at parcel level. Accurate for early siting; a topo survey is required before engineering.

Can it model multiple footprint options?

Yes — site multiple footprints on the parcel and compare grading and orientation implications side-by-side.

Does it consider neighboring buildings?

Solar obstructions and view orientation consider neighboring structure heights where data is available.

Is this needed for flat suburban parcels?

Less critical, but still useful for siting and orientation. The slope read is almost trivial; the orientation read still matters.

What about lot-edge conditions?

Frontage, side, and rear conditions are mapped against the polygon — useful for siting the building relative to neighbors.

Site Analysis Software — Read The Site, Not Just The Parcel

Site analysis is the deeper read that happens after a parcel passes initial diligence. It's where the building footprint is sited, where access and drainage are planned, where the orientation of the structure is decided. It's the bridge between 'we have a parcel' and 'we have a design'.

Buildora IQ's site analysis layer is built around the parcel polygon and its topography — slope distribution across the lot, drainage flow, optimal building orientation given slope and sun, access and circulation, and the implications for grading and site work.

Site vs. parcel analysis

Parcel analysis answers 'can we build here at all?' Site analysis answers 'where on this parcel does the building go, and what does that imply for cost and design?' Parcel is binary; site is configurational. Most developers don't need site analysis on every parcel — only on the ones that have advanced past initial diligence and are entering concept design. That's typically 10-20% of the pipeline.

What the site analysis reads

Slope distribution across the parcel — not just average slope, but where the flat areas are and where the steep areas are. Drainage inferences from elevation. Optimal building orientation given slope and solar exposure. Access points consistent with frontage and any easements. Grading implications for the chosen footprint. The output guides the architect's siting decisions: where to put the building footprint, where to route the driveway, where to handle drainage, where to expect grading cost concentration.

Solar and orientation

Solar orientation matters for both performance (energy cost, daylighting) and design quality (living spaces oriented to view and light). The platform reads the parcel's solar exposure given latitude, orientation, and any obstructions inferred from neighboring structures and topography.

Drainage and grading concentration

Topographic analysis identifies where water flows on the parcel today and where it will flow after grading. This is rough — a civil engineer still does the formal drainage plan — but it's enough to flag drainage challenges before committing to a footprint that creates them.

Use Cases

Slope Distribution Mapping: Where the flat areas are, where the steep areas are — not just averages.
Drainage Inference: Surface flow indication from elevation, suitable for early footprint siting.
Solar Orientation Read: Optimal building orientation given latitude, slope, and inferred obstructions.
Grading Hotspot Surfacing: Where grading cost concentrates given the chosen footprint.
