Selective & Total Demolition Takeoffs
Demolition is more than wrecking — it's a logistics and disposal science. We provide material-by-material debris volumes, equipment hour estimates, and hazmat quantities for every type of structure removal.
Technical Precision in Demolition Estimating
Welcome to F&K Estimatings, your partner for accurate demolition estimating services. Demolition and remediation work carries unique risk — unknown site conditions, hazardous materials, and tight urban logistics can turn a straightforward teardown into a budget-busting operation. We provide the forensic quantification needed to bid demolition work with realistic contingency and full scope coverage.
Our demolition estimators assess every structure by its construction type, condition, and accessibility. We classify materials into disposal streams — concrete and masonry, ferrous and non-ferrous metal, clean wood, treated wood, drywall, roofing, and mixed construction debris — applying standard density factors for accurate volume-to-tonnage conversion.
Selective vs. Total Demolition Quantification
Selective interior demolition demands careful isolation of salvageable systems from removal scope. We quantify demolition by building system — walls and partitions by square foot and assembly type, ceiling grids by square foot, MEP systems by linear foot, fixtures and equipment by piece count. Each system receives a distinct labor productivity rate reflecting the care required to protect adjacent construction.
For total structural demolition, we calculate building volume (cubic feet), structural weight (tons), and debris generation by material type. Our estimates account for sequential demolition phasing, crane and equipment positioning, and drop zone logistics for multi-story structures.
Hazardous Material Assessment
Regulated materials significantly impact demolition cost and schedule. We quantify suspected asbestos-containing materials (floor tile, mastic, pipe insulation, roofing) by square foot and linear foot, lead-based paint by surface area, mercury-containing devices by count, and PCB-containing caulk by linear foot. Each hazmat line item includes specialized abatement procedures, containment, air monitoring, and disposal documentation per EPA and OSHA standards.
The Demolition Precision Advantage:
- Material-by-Material Debris Volumes: Each waste stream is quantified separately using USACE debris density factors for accurate hauling and tipping cost projections.
- Equipment Hour Modeling: Excavator, shear, hammer, and loader hours are calculated based on structure type and production rates per RSMeans and MCAA demolition data.
- Regulatory Compliance Scope: All hazmat handling, dust control, erosion BMPs, and permit requirements are included as explicit line items.
Debris Disposal & Recycling Analysis
Disposal costs can reach 30% of a demolition budget. We calculate debris tonnage by material, apply local landfill tipping fees per ton, and identify recycling credit opportunities for concrete crushing, metal scrap, and clean wood grinding. For projects targeting LEED certification, we document diversion rate potential by material stream.
Utility Disconnects & Site Protection
Before the first hammer swings, utilities must be safely disconnected and the site must be secured. We include temporary utility caps and seals, site fencing and pedestrian protection, dust control measures (water trucks, misting stations), and erosion and sedimentation control BMPs per the SWPPP. These soft costs are frequently overlooked but essential for a compliant demolition bid.

Demolition Cost Drivers
Hazmat Remediation
ACM abatement costs vary by material type and accessibility. Pipe insulation asbestos costs more per linear foot to remove than floor tile.
Urban Access Constraints
Downtown demolition with no laydown area, limited crane access, and street closure permits adds 25-40% to equipment operating costs.
Recycling vs. Landfill
Concrete crushing for on-site reuse reduces disposal costs but adds equipment and processing labor. Local tipping fees vary by $20-80/ton.
Phased Occupancy
Demolition in occupied buildings requires night work, dust barriers, noise mitigation, and phased utility shutdowns that multiply labor costs.
Demolition Specialties
Scope-specific estimates for every demolition type.
