DOT project submittals require: material certifications (mill certs for steel, mix designs for concrete and asphalt, material test reports for geosynthetics); test reports (Proctor compaction, gradation analysis, structural steel inspection); and compliance documentation (manufacturer’s certifications matching the specified product). Submit in the sequence shown on the submittal log; getting approvals ahead of material delivery prevents costly work stoppages.
What Makes DOT Submittals Different
Commercial project submittals are reviewed by the design team in days. DOT submittals go through an agency review process that can take 2–4 weeks or longer for complex items like concrete mix designs or traffic control plans. Submitting late means waiting for approval while materials sit or while work is held. The successful DOT subcontractor submits everything before the specified submission deadline on the schedule, not when they are ready to use the material.
Required Submittal Categories
Material Certifications
For every specified material, the manufacturer must certify that the product meets the specified standard. Common required certifications:
- Structural steel and reinforcing: Mill certificates (heat numbers, test results) must match the material on site. Inspector will check heat numbers against certs.
- Concrete: Mix design with aggregate gradation, w/cm ratio, admixture data sheets, and strength test records. Pre-approval typically required before first pour.
- Asphalt mix: Job mix formula (JMF) with aggregate gradation and binder grade. Must match the plant producing the mix.
- Pipe: ASTM product certification for the pipe class specified (e.g., ASTM C76 for RCP, ASTM D3034 for PVC sewer).
- Geotextile/geogrid: Manufacturer’s certification that physical and chemical properties meet the spec values.
Test Reports
- Proctor compaction test results (ASTM D698 or D1557) for each soil material used as fill or subgrade
- Aggregate gradation tests for bedding, base course, and backfill
- Concrete compressive strength test reports (28-day breaks)
- Asphalt extraction test results
- Structural steel inspection reports (if required by spec)
Compliance Submittals
- Traffic control plans (TCP) with signature block
- SWPPP and BMP documentation
- Safety plan and emergency response contact list
- CPR and OSHA certifications for required crew members
Submittal Log Management
Maintain a submittal log with: item number, description, specification section, date submitted, date approved/returned, revision required, and re-submission date. Review the submittal log weekly at the start of the project and monthly as you approach material procurement deadlines. A missing approval that holds a concrete pour or an asphalt paving day can cost thousands in crew standby.
