Enter project info once — it carries across all tools. Or skip this and use any tool standalone.
Rough Order of Magnitude MEP cost by building type, square footage, location, and quality tier. Broken down by Mechanical, Electrical, Plumbing, and Fire Protection. All assumptions visible and overridable.
Structured walkthrough of 35 line items with editable defaults. Staffing, temporary facilities, insurance, bonds, permits, and closeout. Stop rebuilding the spreadsheet from scratch.
76 common scope gap items across 6 trade interfaces. Assign responsibility, compare sub bids with Bid Leveling mode, export CSV, share via link. Prevent the change orders that cost 5-15% of contract value.
Input your electrical equipment list. Get minimum room dimensions with NEC 110.26 working clearance, dedicated space, headroom, and egress requirements. 2023 NEC compliant.
Input floor-to-floor height and structural depth. Visual stacking diagram shows what fits in the plenum. Building type presets for healthcare, lab, and office. Critical for renovation projects.
Start from base commercial MEP cost, add line-item premiums: medical gas, ASHRAE 170 ventilation, nurse call, redundant power, isolation rooms. Quantifies the healthcare MEP premium.
Estimate HVAC tonnage, electrical service size, generator capacity, plumbing demand, fire protection, and mechanical room sizing. Rules of thumb by building type with climate adjustment. The first question on every pursuit.
Why these tools exist. Every preconstruction team does this math. Most do it in spreadsheets rebuilt from scratch on every pursuit, in enterprise software that costs more than the answer is worth, or from tribal knowledge that walks out the door when people leave.
These tools are free because the knowledge behind them should be free. Every calculation shows its work. Every assumption is visible and overridable. Every number is defensible.
Built for the people who estimate, coordinate, and build MEP systems on real projects — senior living, education, healthcare, commercial. The tools work on your phone, load fast, and don't require an account.
