Complete Estimating Platform

Everything you need to create winning estimates

Digital Takeoff

On-screen takeoff from PDF plans. Measure linear, area, and count quantities. AI assists with common element identification.

AI Cost Prediction

AI learns from your historical data to predict costs. Flags outliers, suggests missing items, and improves accuracy over time.

Cost Databases

Built-in cost data for materials, labor, and equipment. Customizable for your local market and pricing structures.

Assembly Pricing

Build reusable assemblies for common scope items. Price walls, rooms, or systems with one click.

Labor Calculations

Automatic labor calculations based on quantities and productivity rates. Adjust for crew size and conditions.

Proposal Generation

Generate professional proposals from estimates. Customizable templates with your branding.

Bid Integration

Seamless flow from estimate to bid. Import subcontractor quotes and compare to your estimated costs.

Variance Analysis

Compare estimates to actuals. Track accuracy by trade, project type, and estimator to improve future estimates.

AI That Makes You a Better Estimator

Space AI's AI learns from every estimate to help you be more accurate and efficient:

Historical Learning

AI analyzes your past projects to understand your pricing patterns and improve predictions

Missing Item Detection

Automatically identifies scope items commonly included on similar projects that may be missing

Market Comparison

Compare your estimate against anonymized market data to ensure competitiveness

Error Flagging

Highlights quantities or prices that seem unusual based on project characteristics

Frequently Asked Questions

What is construction estimating software?

Construction estimating software helps contractors calculate project costs accurately. It includes digital takeoff tools, cost databases, labor calculations, and markup management. Space AI's estimating module adds AI that learns from your past projects to improve accuracy and speed.

What is the best construction estimating software in 2026?

Space AI is the leading construction estimating software in 2026, combining traditional takeoff and costing with AI-powered predictions. Unlike standalone tools like PlanSwift or Bluebeam, Space AI integrates estimating with bidding and project management for a complete workflow. The AI learns your pricing patterns to improve accuracy over time.

How much does construction estimating software cost?

Construction estimating software ranges from $50/month (basic) to $500+/month (enterprise). Space AI includes estimating in Professional plans at $99/user/month with AI features. Standalone tools like ProEst or Sage Estimating cost $200-500/user/month. Space AI's integration with bidding and PM provides better overall value.

What features should construction estimating software have?

Essential estimating features: digital takeoff, cost databases, labor calculations, assembly pricing, markup management, proposal generation, and reporting. Premium features include AI cost predictions, historical data analysis, real-time material pricing, and integration with bidding/accounting software.

How does AI improve construction estimating?

Space AI's AI improves estimating by: 1) Learning from your historical costs to improve accuracy, 2) Identifying items commonly missed on similar projects, 3) Predicting material price changes, 4) Comparing your estimate to market benchmarks, 5) Flagging outliers that may indicate errors.

Can construction estimating software do takeoffs from PDFs?

Yes, Space AI provides digital takeoff from PDF plans. Use on-screen measuring tools, automatic area calculations, and count features. The AI can identify common elements to speed up takeoffs. Export quantities directly to your estimate or connect with Bluebeam for advanced markup.

How accurate is AI construction estimating?

Space AI's AI estimating achieves 95%+ accuracy when trained on your historical data. The AI gets smarter over time, learning your pricing patterns, local market rates, and project-specific adjustments. It flags estimates that deviate significantly from predictions for manual review.

Does estimating software integrate with QuickBooks?

Yes, Space AI integrates with QuickBooks Online and Desktop. Sync cost codes, track actual vs. estimated costs, and flow estimate data into your accounting system. Also integrates with Sage, Viewpoint, and other construction accounting platforms.
