Takeoff Agent

Agent

Generate reliable quantities from 2D and 3D in minutes—not days. Map elements to CSI/UniFormat, apply assemblies and formulas, reconcile against drawings, and export cost-ready schedules.

(This tool is currently under construction — features may evolve.)
Inputs: RVT/IFC, 2D PDFs, scope lists Outputs: QTO by CSI/UniFormat, Excel/CSV Integrations: Revit, ACC Takeoff, Navisworks Time to Value: 2–4 weeks

Example: 3D + 2D reconciled takeoff with CSI breakout and assembly factors.

Model-Driven QTO

Extract quantities from RVT/IFC by category/type, normalize parameters, and classify to CSI/UniFormat for estimating.

2D Plan Takeoff

Measure areas/lengths/counts on PDFs, apply scale and layers, and tie items to the same cost codes as 3D.

Hybrid Reconciliation

Blend 3D counts with 2D adjustments (e.g., soffits, edge conditions, alternates) and lock rationale for audit.

Assemblies & Factors

Apply labor/consumables/haul factors and composite assemblies (e.g., wall types) with location or phase multipliers.

1) Intake

Load RVT/IFC and/or PDF plan set; choose discipline scopes and cost coding schema (CSI or UniFormat).

2) Classification

Map model categories/types and 2D layers to cost codes; normalize parameters (thickness, materials, level/location).

3) Measurement

Compute quantities from 3D (length/area/volume/count) and perform 2D measurements where model data is missing.

4) Assemblies & Formulas

Apply assembly recipes (e.g., drywall system) and formula rules (waste, laps, spares), with overrides by phase/zone.

5) QA & Reconciliation

Cross-check model vs 2D vs spec; flag anomalies, duplicates, and scope gaps; document adjustments with notes.

6) Output & Sync

Export Excel/CSV by code, location, and phase; generate ACC Takeoff packages or Navisworks Quantification sets.

Works With

Revit (schedules/parameters), IFC, ACC Takeoff (2D/3D), Navisworks Quantification, PDF plan sets.

Deliverables

Cost-code QTO tables (Excel/CSV), reconciliation notes, location/phase pivots, optional ACC/NSQ exports.

Code & Schema

CSI/UniFormat mappings, client custom codes, and multi-level breakdowns (division → spec → assembly → item).

Assemblies Library

Discipline-specific assemblies with editable factors; location/height/condition-based multipliers.

Outputs

Custom columns, naming tokens, workbook templates, and downstream imports for your estimating tools.
