Logan International Airport
Terminal E Modernization
Project Overview
The Terminal E Modernization project at Logan International Airport represents a major investment in the region’s international aviation infrastructure. This large-scale expansion added four new gates and reconfigured approximately 1.5 million square feet of airside and landside areas including aircraft ramps, taxiways, fuel lines, and supporting utility systems. BSI Engineering, Inc. was selected to provide comprehensive Subsurface Utility Engineering (SUE) services across this complex, high-traffic environment ensuring safe and efficient design integration while maintaining uninterrupted airport operations.
BSI’s Role: Subsurface Utility Engineering
BSIE’s SUE scope spanned Quality Level A, B, and C utility investigations, supporting early design coordination, fuel line routing, and critical utility conflict resolution. All work was completed in strict coordination with airport operations and project stakeholders.
Services Provided
Utility Mapping (QL-B & QL-C):
Performed electronic designation and utility records research to map all underground utilities across 1.5 million square feet of airport infrastructure, informing design of new terminal gates and apron areas.
CCTV Storm Drain Inspection
Completed 200 linear feet of internal pipe inspection using CCTV equipment to assess the condition of a key 36” storm drain, providing video documentation and structural condition data.
Fuel Line Utility Coordination & Conflict Matrix:
Supported the design of 3,200 linear feet of new fuel lines crossing active taxiways, ramps, and cargo areas. BSI generated a utility conflict matrix identifying all crossing utilities and supported de-confliction planning with the design team.
Test Pit Investigation (QL-A):
Oversaw excavation of more than 85 vacuum test pits at key utility crossings along the proposed fuel line alignment. Each test pit was logged and documented to verify depth, location, and utility type. Work was performed using non-destructive air vacuum excavation, minimizing risk to surrounding infrastructure.
Operations Coordination & Phasing:
All field work was executed with careful planning and approval from airport operations, tenants, and stakeholders to maintain uninterrupted flight activity and safety during all investigation phases.
Key Results
- Identified and resolved over 85 potential utility conflicts
- Enabled successful routing of new fuel lines through complex airfield corridors
- Provided verified utility data across 1.5M+ square feet of airside terminal space
- Delivered safely, on time, and in full compliance with MassPort requirements
- Supported continuous airport operations throughout construction
