💡 Module 4: Material Costs & Pricing

Convert your takeoff into dollars: quantify materials, apply current pricing, and use quotes or cost databases to build a reliable estimate.

📋 Key Takeaways

  • Translate counts/lengths from takeoff into itemized material lists.
  • Apply unit pricing (per foot/per device) consistently.
  • Refresh prices via vendor quotes and maintain a dated price log.
  • Use cost databases for baselines; override with current quotes.

📌 Core Concepts

From Quantities to Dollars: Convert conduit LF, wire LF, box/device counts, fixture counts, and gear into priced line items.

Unit Pricing: Price by LF (conduit/wire) or per-each (devices/fixtures). Multiply by quantity → subtotal per category.

Quotes & Updates: Request vendor quotes for wire, gear, and lighting. Record quote date and lead time; update your sheets.

Material Categories: Conduit, wire, boxes/devices, lighting, panels/switchgear—each with its own pricing behavior.

🧰 Material Pricing Quick Reference

Category Typical Unit Pricing Notes
Conduit (EMT/PVC/RMC) LF Bundle by size; elbows/fittings priced per-each.
Wire/MC Cable LF Copper pricing volatile—use fresh quotes; include scrap factor.
Devices/Boxes EA Group by type (GFCI, duplex, switch); include plates/straps.
Lighting/Fixtures EA Spec-driven; confirm alternates, controls, and lead times.
Panels/Switchgear EA/System Always vendor-quote; verify AIC rating, spaces, accessories.

💡 Pro Tips for Material Pricing

Date everything: keep a pricing log with vendor, contact, and quote date—attach PDFs/emails.

Apply wastage factors: add cut loss/scrap (e.g., +5–10% wire) as a separate line to stay transparent.

Lock assumptions: list inclusions/exclusions (e.g., fixtures by others, no seismic bracing) to reduce change orders.
