Arkansas Takeoff Scope Verification Checklist
Confirm the project jurisdiction in Arkansas
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 Benton County, Pulaski County, Washington 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
