Question 1

What are INDOT compaction documentation requirements?

Accepted Answer

INDOT (Indiana Department of Transportation) uses AASHTO T180 Modified Proctor as its compaction standard for state highway projects. Field logs must include project number, section, station/offset, material type, lift thickness, lab MDD and OMC, field density (nuclear gauge with gauge ID), field moisture, percent compaction, ambient temperature, and inspector certification number. INDOT standard: 95% for embankment, 97% for subgrade, and 100% for utility trench backfill within road right-of-way. INDOT uses SiteManager for project documentation on major highway contracts.

Question 2

Does Indiana have its own OSHA State Plan?

Accepted Answer

Yes. Indiana operates its own OSHA State Plan (IOSHA — Indiana Occupational Safety and Health Administration) under the Indiana Department of Labor. Indiana OSHA covers both private and public sector construction and is at least as stringent as federal OSHA. Documentation requirements include OSHA 300 logs, incident reports (fatalities within 8 hours, hospitalizations within 24 hours to IOSHA), toolbox talk records, equipment inspection logs, and training certificates. IOSHA has historically focused enforcement on construction fall protection and trench safety.

Question 3

What contractor licensing is required in Indiana?

Accepted Answer

Indiana does not have a statewide general contractor license for private commercial or residential construction. However, public works projects (state and local government work) require contractor registration. Specialty trades — electrical, plumbing, and HVAC — are licensed through the Indiana Professional Licensing Agency (PLA). Local jurisdictions vary: Indianapolis/Marion County, Fort Wayne/Allen County, and other major cities have local contractor registration requirements for permits. Always verify local requirements before pulling permits.

Question 4

What are the major construction markets in Indiana?

Accepted Answer

Indianapolis is the dominant construction market, with major commercial, healthcare, and highway construction. The I-465 loop reconstruction and I-70/I-65 interchange are among the largest DOT projects. The Indiana Economic Development Corporation has attracted major battery manufacturing investment (Stellantis-Samsung, Eli Lilly expansion) driving significant industrial construction in Columbus, Lebanon, and Kokomo. Fort Wayne is the second-largest market with commercial and industrial growth. South Bend has university construction (Notre Dame) and manufacturing.
