Project Overviewx

Construction Phase Management Services: Extension of Staff Inspection Services

This design-bid-build toll facility project will widen the Dallas North Tollway to 4 NB and SB main lanes, with main lane and frontage road paving, ramp reconstruction, bridge construction, drainage improvements, aesthetic treatments and ITS components.

Hayden’s responsibilities include managing the subconsultant inspection staff. Hayden was brought onto the project 13 months after Notice to Proceed. Our inspectors quickly established communication with existing inspection staff, NTTA personnel and field crews to maintain job progression to act as staff inspection augmentation for the prime consultant and the end client. Hayden staff monitors and records daily construction progress, provides updates to the client and NTTA staff and manages field change requests.

Inspection Approach & Lessons Learned

Our inspection team was responsible for mitigating an issue with traffic-rated inlets on the frontage roads that connect major Plano thoroughfares with the NTTA facility. It was determined that there was a discrepancy between the general notes, inlet plans and shop drawings regarding the steel coverage. This was resolved in the field with the contractor and new inlets were installed with minimal traffic disruption.
