Recorded Violations and Out-of-Service Status

A recorded violation is what an inspector wrote down at the roadside. It is not a penalty, and it is not an amount owed: FMCSA assesses civil penalties only after a compliance review classifies specific cited violations. The step that changes this record is the document behind each line, so the next move is to see which records an investigator would ask for and which of them exist today.
What a 89/100 Carrier Intelligence Score Means
The Carrier Intelligence Score is FileFlo's own summary of three public FMCSA components for SCHILDBERG CONSTRUCTION CO INC: the safety rating, the inspection pass rate and the out-of-service rate against the national average. It is not an FMCSA score, and FMCSA does not use it to choose carriers for an investigation. 89 out of 100 falls in FileFlo's Low Risk band.
Iowa Trucking Compliance: GREENFIELD Area Carriers
SCHILDBERG CONSTRUCTION CO INC falls under the Midwestern Service Center for FMCSA field-office oversight (region code 07). Service-center territory drives which FMCSA Investigator team would conduct a new-entrant audit or compliance review if one is triggered for this carrier.
Authority Type, Hazmat Status, and Operating Profile
SCHILDBERG CONSTRUCTION CO INC is classified by FMCSA as an interstate carrier.
The carrier is classified as Private Property, meaning it transports its own goods incidental to its primary business, exempt from MC-number authority but still subject to safety regulations under 49 CFR Part 390.
Business organization type: Corporation.
SCHILDBERG CONSTRUCTION CO INC is not flagged in FMCSA Census as a hazmat carrier (HM indicator: N), so the carrier is not subject to the additional 49 CFR Subchapter C hazmat regulations.
Operational range per MCS-150 filing: interstate within 100 miles (short-haul, 15 drivers); intrastate within 100 miles (10 drivers). The 100-mile boundary matters because drivers operating within a 100-air-mile radius qualify for the short-haul exception under 49 CFR 395.1(e)(1), which removes the requirement to maintain RODS for the day.
Self-reported MCS-150 annual mileage: 229,333 miles. MCS-150 mileage feeds the FMCSA SafeStat exposure denominator: drastically understated mileage can artificially inflate CSA BASIC percentile scores by reducing the per-mile exposure baseline. Updates are required every 24 months under 49 CFR 390.19.
Fleet Composition and Driver Profile
Owned equipment per the FMCSA Census filing: 34 straight trucks, 5 tractors, 5 trailers. Owned-vs-leased equipment matters for compliance documentation, owned trailers require the carrier to retain annual inspection certificates under 49 CFR 396.17, while leased trailers shift that documentation responsibility to the lease agreement.
The carrier reports 25 CDL-holding drivers on file. Each CDL driver must have a current Driver Qualification File (DQF) maintained per 49 CFR 391.51, including a Medical Examiner's Certificate, an annual MVR review, and a record of road-test results.
Intrastate driver count: 10. Intrastate drivers may be subject to state-specific CDL endorsement and hours-of-service variances depending on the state.
Primary cargo type per MCS-150: Rock Aglime. Cargo type drives which BASIC categories the carrier is monitored under (Hazmat Compliance applies only to HM-flagged carriers; Cargo-Related Crash applies broadly).
FMCSA Crash History
The FMCSA Motor Carrier Management Information System (MCMIS) crash dataset records 14 crash events involving SCHILDBERG CONSTRUCTION CO INC in the available reporting window. Of these, 2 involved a fatality, 7 involved a reported injury, and 13 resulted in a tow-away. 14 events meet the federal-recordable threshold under 49 CFR 390.5 (fatality, injury treated away from the scene, OR tow-away of any vehicle).
Most recent recorded event: 620TH ST, IA on July 19, 2021.
How SCHILDBERG CONSTRUCTION CO INC Compares to the National Average
Across the 6 recorded inspections, SCHILDBERG CONSTRUCTION CO INC's 16.7% vehicle out-of-service rate sits slightly below the FMCSA 2024 national average of 20.72%. The 0.0% driver out-of-service rate sits materially below the 2024 national average of 5.51%.
