New features
Bid engine
Construction, low-voltage, and electrical bidding — replaces an Excel cost workbook with a deterministic server-side cost engine and AI-assisted takeoff. Upload spec documents and drawings and NEXOS CORE reads the drawings with Claude Vision to count devices, generates trade-grouped line items, applies issued addendums via a reviewable diff, writes a scope-of-work narrative, and runs a red/yellow/green pre-submission audit that blocks submit on red findings. Cost math is deterministic — material + tax + subs + equipment + labor + burden roll up to hard cost, then overhead, profit, contingency, commission, sales tax, permits, and bond to grand total, with profit per man-day, margin %, and an optional manual bid-price override. See Bid engine.Drawings
System of record for a client site’s technical drawings — floor plans, network and riser diagrams, cable paths, rack elevations, conduit layouts, and as-builts. Uploads support 11 drawing types up to 64 MB with full revision history, scoped to a company, survey, bid, or project. Run Analyze floor plan on an image drawing and Claude Vision extracts rooms, doors, corridors, and safety features to render a server-side isometric 3D view — no plugins, just SVG. For drawings attached to a bid, an AI takeoff counts low-voltage devices and cable runs and feeds the bid engine’s reconciliation, gated to the trades that bid actually covers. See Drawings.Field survey
iPad pre-bid site assessment for low-voltage and IT infrastructure work. A tech walks a prospective job site and captures a room-by-room inventory — GPS-tagged photos grouped by area and floor, voice notes that Claude transcribes and extracts into structured survey items and area attributes (ceiling type, height, square footage), and AI equipment detection that reads nameplates from photos for manufacturer, model, serial, plus a photo-quality score and code-violation flags (NEC, NFPA 72, TIA-568, UL 294). A completed survey converts one-tap into a draft bid — each area becomes a section and each item needing work becomes a line item, with pricing added downstream. See Field survey.Known limitations
- Bid engine — AI takeoff, reconcile, addendum diff, and scope summary require your tenant’s Claude API key and carry a per-drawing cost. Confidence scores on generated line items are AI estimates — verify before submit. The Dedupe by tag heuristic on Vision Findings can drop a legitimate sheet; review before applying.
- Drawings — AI features are image-only (PNG/JPG/WebP). PDF, DWG, and SVG files are stored but can’t be analyzed. Drawing annotations (pins, notes, measurements) aren’t available yet.
- Field survey — voice capture is transcript-only (no audio file is stored) and depends on the browser’s speech recognition, so non-Chrome/Safari browsers won’t capture. GPS coordinates come from the device and aren’t server-validated. AI detection is on-demand and needs your tenant’s Claude API key. Conversion to a bid requires the survey to be marked completed.
