Kentucky Takeoff Scope Verification Checklist
Confirm the project jurisdiction in Kentucky
Remote estimating starts with the project address and issued documents. A service-area name does not determine the permit authority, utility requirements, wage basis or actual site conditions.
For the areas discussed here, including Jefferson County, Fayette County, Boone County, identify the authority and utility serving the actual parcel rather than applying a statewide assumption.
- Share the permit cover sheet or designer’s code summary, adopted edition and local amendment references.
- Provide utility connection details, meter/backflow selections and the civil-to-building package handoff.
- Use project geotechnical and engineered details for burial, excavation, soil protection and restraint quantities.
- Identify public/private funding and the applicable wage determination before supplying labor rates.
Regional code, soil and wage descriptions on this page require project-specific verification. They are not a permit approval, site survey or published local labor quotation.
Images illustrate estimating subjects. They do not document our local office, a completed client project or local jobsite experience.
- ICC code adoption information and IAPMO adopted-code information
- Federal wage determination records; confirm any separate state/local requirements with the relevant authority.
- Reconcile civil and building plumbing plans
- Send the jurisdiction and drawings for a scope review

Labor Environment & Prevailing Wage Considerations
How commercial mechanical contractors model labor productivity and regulatory wage determinations in Kentucky.
Kentucky is a right-to-work state under KRS 336.130. Kentucky repealed its prevailing wage law for state and local public works in 2017 (House Bill 3).
Private commercial and municipal public works projects operate in a competitive open-shop contracting environment.
Federal government construction projects (Fort Knox, Fort Campbell, Blue Grass Army Depot, VA healthcare facilities) require compliance with federal Davis-Bacon wage rates.
United Association locals (UA Local 502 Louisville, UA Local 452 Lexington, UA Local 392 Northern KY/Cincinnati) maintain strong market share across automotive plants, distilleries, and commercial high-rises.
Winter freezes in northern and eastern Kentucky and summer heat require seasonal labor adjustments for site excavation and unconditioned building rough-ins.
State-Specific Plumbing Estimating Workflow in Kentucky
The 9-step preconstruction process mechanical estimators follow to produce audit-ready bid deliverables.

Verify compliance with the Kentucky State Plumbing Code and DHBC Division of Plumbing submittal criteria.
Itemize all commercial plumbing fixtures, carrier assemblies, commercial water heaters, and booster pumps.
Quantify linear footage of domestic water, sanitary DWV, storm conductors, and natural gas lines by size and spec.
Calculate excavation, pneumatic rock-hammering allowances, and aggregate bedding for Bluegrass limestone.
Apply competitive commercial open-shop rates or Davis-Bacon wage determinations for federal work.
Obtain current local plumbing wholesale quotes for pipe, valves, fittings, and specialized equipment packages.
Clearly document trade cutoffs (e.g. 5 feet outside building wall, mechanical equipment connections).
Compile itemized Bill of Materials, labor hour summaries, and subcontractor proposal letters for GC submission.
