🎯 Learning Objectives

• Estimate debris volume, weight, loads, and total hauling/tipping cost.
• Select dumpster sizes and quantities that fit site constraints and fee structures.
• Compare volume-based vs weight-based pricing and pick the cheapest path.
• Plan recycling streams and calculate diversion rates for submittals.
• Identify salvage candidates and calculate net value after careful-removal labor.

🚛 Estimating Debris Volume & Hauling Costs

Convert areas to volume (CY) using thickness, then to tons with a density factor. Size your trucking/dumpsters and include tipping, permits, fuel surcharges, and multiple hauls for tight sites.

• CY = (SF × Thickness(in)/12) ÷ 27  ·  Tons = CY × Density(ton/CY)
• Plan for bulking (loose debris inflates volume) and compaction (some facilities compact).
• Short laydown? Use smaller, more frequent containers—price extra mobilizations.

🗑 Dumpster Sizing & Pricing

• Common sizes: 10 / 20 / 30 / 40 CY. Match to site access, ceiling heights, and floor load limits.
• Separate clean loads (metal, concrete) for lower fees or credits; keep contamination out.
• Confirm daily rental, overage thresholds, ton caps, and standby/relocation fees.

⚖️ Volume vs. Weight-Based Fees

• Volume model: charged by container size & hauls; good for light debris.
• Weight model: charged per ton; best for heavy materials (concrete, CMU).
• Some facilities blend both—ask for the exact matrix and minimums.

🔄 Identifying Recyclables & Streams

• Metals: steel, copper, aluminum (scrap credits possible).
• Concrete/Asphalt: crush for base, lower fees vs landfill.
• Wood/Gyp/Cardboard: diversion where markets exist; watch contamination.
• Document facility receipts & weight tickets for diversion reporting.

💰 Salvage Value & Resale

• Candidate items: doors/frames/hardware, light fixtures, casework, RTUs, decorative metals.
• Include careful removal labor, protection, and storage/handling.
• Decide if credit reduces bid price or is billed as a separate owner option.

✍️ Suggested Clarifications (copy/paste)

• Disposal at licensed facilities; tipping priced per provided fee schedule; weight overages billed at actuals.
• Clean-load recycling assumed for metal and concrete where feasible; contamination charges by owner/GC.
• Salvage credits contingent on reusable condition and access; careful-removal labor priced separately.
• Permits, street use, and container staging per plans; additional mobilizations are a unit price per trip.
• Weight tickets and diversion summary provided at closeout; facility receipts included.
