How accurate are the material takeoff and cost calculations?

Calculations are grounded in industry-standard engineering formulas (such as compacted density multipliers, ASTM standards, and CSI MasterFormat divisions), with customizable local material unit costs and compaction waste factors.

What waste allowance factor should be added to material orders?

For commercial and residential trade installations, standard engineering practice recommends including a 5% to 10% material waste and compaction contingency factor.

Can I export these takeoff sheets for client bidding?

Yes, you can export full itemized material schedules and bid breakdowns directly to CSV or printable takeoff summaries.

Rigging & Erection Engineering Note:

Tilt-up panel erection requires accounting for the initial breakaway suction coefficient (typically 20% to 30% additional force) when peeling the green panel off the casting slab. A crane's rated capacity diminishes drastically with boom radius; ensure the crane chart exceeds the total rig plus rigging hardware at the maximum working radius.
