ILLUSTRATIVE APPLICATION BASED ON PUBLIC REQUIREMENTS
This conditional illustration uses public documents. It is not a ConstructQuant client, completed project or account of local project experience. No project quantities or prices are assumed.
Establish the closed crawl-space document basis
Conversion to closed crawl space under the project-confirmed 2018 NCRC R409 basis; later/alternative project bases require separate confirmation. Methods are alternatives, not a combined required package. No equipment sizing, duct airflow or contractor-license claim for ConstructQuant. Other trade licensing is not settled by the interpretation.
Measure the selected humidity-control method
If the detail selects a dehumidifier, do not silently price a supply-air branch as its equivalent. If it selects supply air, trace the branch route and connection to the mechanical package. Carry only assigned drain/power work shown in the plans, and keep permit or licensed-trade responsibility explicit.
Separate HVAC connections from permit and trade allocation
The moisture-control choice changes the physical estimate package and trade split, beyond generic code-edition control. Specific NC interpretation plus method comparison cannot be replaced with South Carolina future-code dates.
Trace the document into the estimate
- Official basis
- North Carolina Office of State Fire Marshal: Closed crawl-space humidity method and permitting interpretations. 2018 code current listing checked October 5, 2026; R409.5 interpretation March 20, 2019; permit interpretation December 11, 2025. Humidity method table p. 2; permit interpretation Section 106.1
- Project documents
- Accepted crawl-space detail, selected R409.5 humidity-control method, mechanical/electrical layouts and permit responsibility.
- Documented condition
- OSFM distinguishes dehumidifier, supply air, house air, exhaust fan and conditioned-space methods; supplied/conditioned HVAC paths have a different H-3 allocation from standalone methods. Conversion requires the permit basis described by the current interpretation.
- Affected scope
- Designer-selected humidity equipment or HVAC branch package and separately assigned electrical/other connections.
- Possible estimate items
- Selected dehumidifier EA or supply-air duct branch LF/fittings; specified power/drain connections where shown; allocated permit responsibility.
| Decision | Inspect | Possible scope row | Check before pricing |
|---|---|---|---|
| Standalone moisture equipment | Selected crawl-space humidity detail | Specified dehumidifier and assigned connections | Do not assume a supply-air method instead. |
| Supply-air method | Accepted mechanical branch detail | Duct route, fittings and connection scope | Use the selected method; not every method together. |
| Trade and permit split | OSFM interpretation plus contract responsibilities | Explicit allocation of work/fees if requested | The resource does not certify any contractor license. |
Source references and limits
Methods are alternatives, not a combined required package. No equipment sizing, duct airflow or contractor-license claim for ConstructQuant. Other trade licensing is not settled by the interpretation.
This proposed estimating resource does not determine engineering/design, permit approval, insurance eligibility, environmental design, legal applicability or code-compliance certification. Refer project applicability and design decisions to the responsible designer, authority or operator. This is a resource boundary, not a separately confirmed exhaustive company service exclusion.

Remote services and agreed deliverables
ConstructQuant provides quantity takeoff, material takeoff, cost/priced estimates and bid estimating remotely for projects across the United States. Remote coverage does not imply physical offices, local teams or local project history. The agreed project scope determines the services and outputs included.
Excel, PDF and quantity worksheets are supported deliverables. Marked drawings, material lists, scope notes and other outputs are project-dependent. Only deliverables included in the project’s agreed scope are promised.
Workflow: Plans/specs → Scope review → Quantity/material takeoff → Pricing/cost estimate where requested → QA/review → Final deliverables
Send the issued plans/specifications and the estimate purpose for scope review. Identify the requested trades, document revisions and any unresolved details before agreeing the output package.
