South Dakota Takeoff Scope Verification Checklist
Confirm the project jurisdiction in South Dakota
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 Minnehaha County, Pennington County, Lincoln 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

South Dakota Plumbing Code & Regulatory Environment
Commercial plumbing in South Dakota is regulated statewide by the South Dakota State Plumbing Commission within the Department of Labor and Regulation (DLR), pursuant to SDCL Chapter 36-25.
State Adoption Structure
South Dakota adopts the model Uniform Plumbing Code (UPC) with state-specific amendments codified in ARSD 20:54. The code applies uniformly statewide across all 66 counties.
State vs. Local AHJ Authority
State plumbing commission inspectors inspect commercial projects across the state, working in coordination with municipal departments in Sioux Falls and Rapid City.
Key Statutory Plumbing Requirements:
- Commercial plumbing installations must be permitted by a licensed South Dakota Plumbing Contractor.
- Direct supervision ratios require one licensed journeyman plumber for each registered apprentice on commercial jobsites.
- Backflow prevention assemblies must comply with South Dakota Department of Agriculture and Natural Resources (DANR) rules.
- Grease interceptor installations must comply with local municipal sewer pretreatment ordinances.

Deep trench excavation (54" to 66" cover), washed stone bedding, laser-graded underground pipe installation, and backfill.
Regional Construction Conditions & Site Geotechnical Factors
Regional factors to confirm against the project geotechnical report, engineered details, and permit requirements.
Eastern South Dakota (Sioux Falls) requires 54 to 60 inches of burial depth. Western South Dakota and the Black Hills require 60 to 66 inches due to prolonged sub-zero winter temperatures. Deep burial and trace heating are critical estimating considerations.
Central and western South Dakota feature expansive Pierre shale with high swell potential. The Black Hills (Rapid City) feature dense granite and limestone bedrock requiring rock-hammering. Eastern SD features glacial till.
Commercial projects along the Big Sioux, Missouri, and James river bottomlands encounter elevated water tables requiring trench dewatering.
South Dakota is situated in low seismic hazard categories (Category A and B). Highly alkaline soils require polywrap encasement on buried metal piping.
I-90 and I-29 intersect major markets; severe winter blizzards require temporary heating and scheduling contingency allowances.

Labor Environment & Prevailing Wage Considerations
How commercial mechanical contractors model labor productivity and regulatory wage determinations in South Dakota.
South Dakota is a constitutional right-to-work state under SDCL § 60-8-3. State-funded public projects do not require state prevailing wages.
Private commercial and municipal public works projects operate in a competitive open-shop contracting environment.
Federal military and civil installations (Ellsworth AFB, VA healthcare facilities, federal tribal trust projects) require compliance with federal Davis-Bacon wage rates.
United Association locals (UA Local 300 / UA Local 33) maintain active market share across healthcare campuses, defense facilities, and industrial manufacturing plants.
Prolonged freezing winter weather between November and March requires productivity adjustments for deep trench excavation, ground thawing equipment, and temporary heat.

Calculate excavation, trench box shoring, and washed stone bedding volumes for 54" to 66" burial depths.
Apply competitive commercial open-shop rates or Davis-Bacon wage determinations for federal/defense 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.
