Our Mechanical Estimating Process
Every mechanical estimate follows our proven five-step process:
- Plan Review — Our estimators review all mechanical drawings, specifications, and addenda to understand the full scope
- Quantity Takeoff — We measure every pipe, duct, valve, fitting, and piece of equipment using PlanSwift and Bluebeam
- Pricing — Material costs are sourced from regional distributors with current pricing, and labor hours are calibrated to zip-code-specific rates
- Bid Package Assembly — You receive editable Excel with line-item detail by CSI division, color-coded marked-up plans, and a PDF summary
- Revisions & Support — We provide free revisions when scope changes and remain available to answer questions during the bid process
Mechanical Software & Tools
Our estimators utilize industry-standard digital tools:
- PlanSwift — Mechanical quantity takeoff and measurement
- Bluebeam Revu — Digital plans and markup
- Trimble Accubid — Mechanical cost database and estimating
- RSMeans — Regional labor and material cost data
- DuctCalcPro — Duct sizing and pressure drop calculation
- PipeCalc — Pipe sizing and hydraulic analysis

Frequently Asked Questions
What mechanical systems can you estimate?
We estimate all mechanical systems including HVAC (heating, ventilation, and air conditioning), plumbing (domestic, sanitary, storm drainage, fire suppression), and piping systems (process piping, steam, hydronic, compressed air, and medical gas).
How do you price mechanical labor?
Labor hours are calibrated using zip-code-specific RSMeans data and our historical project databases. We account for local wage rates, productivity factors, and regional market conditions.
Can you estimate only part of a mechanical project?
Yes, we provide estimates for full mechanical packages or individual systems. Just specify which scopes you need estimated and we will focus our takeoff on those divisions.
What file formats do mechanical estimates come in?
Every mechanical estimate includes editable Excel with line-item detail organized by CSI division, a PDF summary for bid submission, and color-coded marked-up plans showing exactly what was counted and where.
How do I submit my mechanical plans for estimating?
Email your mechanical drawings and specifications as PDFs to info@professionalestimatingllc.com or call +1 (908) 488-9245. We also accept partial drawing sets — a complete set including mechanical, architectural, structural, and MEP documents gives the tightest numbers.
