As the prime consultant under a five-year agreement with PennDOT District 6-0, TPD is completing the routine inspections of 251 State-owned bridges with spans less than or equal to 20 feet in Chester County, PA. The bridge types included precast box culverts, slab bridges, concrete T-beam bridges, concrete encased steel I-beam bridges, steel stringer bridges, corrugated metal pipes and pipe culverts, and stone masonry arches. Work is being performed in accordance with PennDOT and FHWA NBIS procedures utilizing PennDOT iForms for data collection and upload to PennDOT’s BMS2 database.

Several of the bridges are Permit Required Confined Spaces requiring special safety precautions such as gas monitoring equipment to inspect the structures. TPD’s inspectors are certified as entrants, attendants, and supervisors for performing confined space inspections in accordance with 29 CFR 1910.146.
