Site Access, Safety & Physical Constraints
Verify logistical obstacles that silently consume crew hours before physical work begins.
Direct driveway access vs. street permit required (adds logistics time).
Active site hookups confirmed, or generator/compressor needed.
Vacant property vs. fully furnished / occupied (requires dust containment & floor protection).
Standard 8-9ft vs. vaulted/12ft+ (requires scaffold, ladders, or scissor lift).
On-site dumpster permitted, or requires debris haul-away / dump trailer fee.
Lockbox code verified, secure lockup for tools & materials, hazard barricades.
Substrate & Hidden Conditions Audit
Physical surface tests to protect yourself against tear-out surprises and uninspected substrates.
Drywall, subfloor, or plaster checked for structural damage, soft spots, or rot.
Below 12-15% on timber/masonry before paint, tile, or flooring application.
Asbestos/lead paint hazard risk flag or multiple old layers requiring heavy sanding/grinding.
Buried conduit or shallow pipe risks mapped before trenching, cutting, or drilling.
Framed openings, floor deflection, and wall plumb checked to prevent trim or cabinetry fitment gaps.
Supply/return register locations, duct sealing during demo, and active exhaust ventilation verified.
Scope Clarification & Client Expectations
Lock down exact quality baselines, homeowner procurement boundaries, and payment thresholds.
Spec sheet confirmed (e.g., Level 4 vs. Level 5 drywall, specific paint sheen, tile grout type).
HOA / landlord permitted working hours confirmed (e.g., 8:00 AM – 5:00 PM).
Contractor provides all materials vs. homeowner supplying fixtures (specify warranty boundary).
Hard surface ram board, zip-wall dust containment, and daily broom-clean threshold documented.
Written sign-off requirement for undiscovered conditions prior to executing additional scope.
Upfront material deposit (typically 30-50%) and progress milestone payments agreed before mobilization.
The Field Math Box: Practical Estimating Formulas
Apply these non-negotiable overhead multipliers before finalizing your bid price.
| Cost Vector | Standard Formula | Contractor Rationale |
|---|---|---|
| Direct Material Factor | Measured Quantity × 1.15 | Guarantees a 15% waste allowance for cut-off scrap, transit breakage, pattern repeats, and irregular surface tolerances. |
| Mobilization Buffer | (Labor Hours × Rate) + 1.5 Hours | Covers morning truck loading, heavy commuter traffic, jobsite safety briefing, tool tear-down, and daily broom cleanup. |
| Disposal & Haul Math | Flat Allowance + ($X / cwt or ton fee) | Base trailer mobilization + landfill tipping fees by weight. Prevents eating $450 transfer station overload charges. |

Standard Field Exclusion Snippets
1-click copy directly into your QuoteFast proposal's Notes & Terms section.
Snippet 1: Concealed Defect Clause
Protects against rotten joists, buried wiring & non-code plumbing found upon tear-out.
“Estimate reflects visible surfaces only. Any hidden structural rot, unrecorded plumbing alterations, or sub-surface electrical issues discovered upon tear-out will be documented and billed separately as a Change Order at standard hourly rates.”
Snippet 2: Material Escalation & Availability
Guards against supplier price spikes and lumber / copper volatility.
“All quotes remain valid for 14 calendar days from date of issue due to supplier material pricing fluctuations.”
Snippet 3: Client-Supplied Goods Policy
Disclaims liability for homeowner-purchased fixtures that leak, arrive late, or fail.
“Workmanship warranty applies strictly to contractor-supplied items and labor. Any homeowner-supplied fixtures must be on-site prior to scheduled installation.”
