SP4N is the AI operating layer for construction strategy, risk, and project controls. It reads drawings, specs, schedules, RFIs, contracts, vendor data, and weather context to surface scope, sequencing, procurement, cost, and delay risk with source-linked evidence.
Every upload moves through four stages - parsed inputs, LLM extraction, the evidence graph, and risk intelligence - and every finding lands with a source reference attached.
Drawings, specs, and RFIs uploaded as project records.
Activities, quantities, dependencies, and constraints extracted.
Every item linked into one source-backed evidence graph.
Delay risk scored daily, per activity, with the reason why.
Upload drawings, specs, schedules, RFIs, submittals, and Office files. SP4N extracts activities, quantities, dependencies, and constraints into reviewable project records.
Scope, sequencing, critical path, procurement, vendor, cost, and weather signals in one source-linked control layer. Editable, auditable, exportable to P6 and MS Project.
Weather, supplier lead-times, and jobsite reports feed back into the live control plan. Delay risk is scored daily, per activity, with the exact reason why.
SP4N cross-references every subcontract scope item against the drawing package - line item by line item, sheet by sheet - to surface scope gaps, scope creep, quantity mismatches, spec conflicts, and change-order risks. Every finding lands with a dollar-impact estimate, the exact contract reference and drawing reference, and a recommended action you can take this week.
Drag in the drawing set, specifications, and any RFIs or submittals you already have.
Activities, sequencing logic, crews, quantities, and constraints are pulled from the documents.
Drop in the subcontract - SP4N flags missing scope, scope creep, quantity mismatches, and change-order risks before they hit the field.
Edit activities, adjust calendars, validate scope and procurement logic. Every change is version-controlled.
Weather, supplier, and field feeds update risk daily. Export to P6, MSP, or share view-only links.
For most project teams, a single avoided delay pays for the platform. Create an account to start building project intelligence.
