T.F. Green International Airport

BSI Engineering, Inc. is proud to serve as the Subsurface Utility Engineering (SUE) consultant to the engineering design team for the Rhode Island Airport Corporation’s (RIAC) multi-airport Capital Improvement Program (Contract No. 34322), spanning Fiscal Years 2024–2029. Our first assignment under this contract involved the rehabilitation and restoration of Runway 5-23 at T.F. Green International Airport—a key airfield component with over one mile of active runway pavement and associated infrastructure.

BSI Engineering, Inc. provided full-scope SUE services to support early design and construction coordination. All work was performed to ASCE 38-22 standards, in close collaboration with RIAC and C&S Companies.

Utility Designation (QL-B):

Electronic locating and mapping of underground utilities over more than 6,200 linear feet of runway—spanning over 500 feet in width—helped the design team understand subsurface conditions and identify potential utility conflicts.

High-Pressure Jetting & CCTV Inspections:

Over 5,400 linear feet of existing storm drain infrastructure were inspected using high-pressure jetting followed by closed-circuit television (CCTV) inspection. These assessments were conducted in compliance with NASSCO PACP standards, providing detailed pipe condition and alignment data.

Vacuum Excavation (QL-A):

Performed six (6) non-destructive test pits using air vacuum excavation. This work provided critical vertical and horizontal location data at points of known utility concern.

Survey & CAD Integration:

All utility mapping was surveyed and delivered in CAD to align with the design team’s workflows and support cross-disciplinary coordination.
