Case Study | Complex Airport Repair


+ Precision repair above a critical operating area
A HIDDEN LEAK. TSA DIRECTLY BELOW. ONE ACCOUNTABLE TEAM.
A persistent leak beneath Delta lounge showers required more than another service visit. ASI connected investigation, controlled demolition and specialist repair inside a restricted airport environment.
Overview
Challenge
Several firms had been unable to locate the leak. The showers were out of service, with water reaching the TSA area below. Concealed piping, limited access and noise restrictions made every intervention consequential.
ASI Approach
ASI coordinated diagnostic specialists and field crews, sequenced controlled openings, protected retained finishes, and aligned access with airport requirements. Findings drove targeted supply and vent repairs, followed by testing.
Results
- Concealed leak paths investigated and repaired.
- Cold-water and vent piping tested after repair.
- One team connected access, demolition and plumbing.
DELTA AIR LINES | LOS ANGELES INTERNATIONAL
The value was control of a difficult problem in a sensitive operating environment. ASI combined construction access, specialist diagnosis and accountable field coordination to move from an unresolved leak to a tested repair.

The repair interfaces
The Water Path Was Hidden. The Repair Had to Be Coordinated.
The shared wall connected shower fixtures, concealed supply piping and vent risers passing through the floor. ASI organized access and trade sequencing around those interfaces.
Conditions Dictated the Next Step
When non-invasive testing could not resolve the concealed path, controlled openings gave the specialists the access required. Nighttime access, escorts, noise control and protection had to align before demolition and repair could move forward.
The ASI Delivery Model
FIND THE CAUSE. CONTROL THE ACCESS. CONNECT EVERY STEP OF THE REPAIR.
ASI managed the dependencies around the specialist plumbing work: where crews could enter, what could be opened, what needed protection and how each finding changed the next intervention.
INVESTIGATED THE CONCEALED PATHS
Camera inspections and repeated fixture, drain and pan tests narrowed the problem inside the shared wall and floor penetrations.
ALIGNED CREWS WITH AIRPORT REQUIREMENTS
ASI coordinated site contacts, escorts, protection and restricted work windows. Noise-sensitive demolition was moved to nighttime.
CREATED CONTROLLED REPAIR ACCESS
Selective removal of tile and backing opened the required wall area, connecting the investigation to physical access for the repair.
COORDINATED SPECIALIST PIPE REPLACEMENT
The team replaced the leaking cold-water section and affected cast-iron vent piping, with supports and sealed floor penetrations.
VERIFIED THE REPAIRED PIPEWORK
The plumber tested the new piping and recorded no leaks at that time. ASI documented the repair and coordinated the next scope.
One Team Controlled Every Dependency
Planning, security coordination, protected demolition, specialist plumbing and testing operated as one connected field plan. The work advanced through findings, not assumptions.
The Outcome
THE LEAK WAS LOCATED. THE REPAIR WAS TESTED.
ASI brought structure to a persistent problem, connecting targeted investigation and construction access with the specialist repair. The completed scope was the leak investigation, selective demolition and plumbing repair.
Successive inspections connected the observed water paths to accessible repair locations.
Affected pipework was replaced and floor penetrations were resealed.
New piping was tested with no leaks observed at that time.
What the Project Delivered
A DIFFICULT PROBLEM RESOLVED
A leak that had resisted prior investigations moved through targeted access to an executed repair.
CONTROLLED CONSTRUCTION ACCESS
Demolition and protection were coordinated around the retained lounge and airport requirements.
CONNECTED SPECIALIST DELIVERY
ASI linked the client, site team and plumbing specialists through one coordinated sequence.
VERIFIED REPAIR PERFORMANCE
The replacement pipework was tested, with no leaks observed at the time of testing.
One Accountable Partner. FROM INVESTIGATION THROUGH TESTED REPAIR.
Delivery Result
For facilities managers, ASI connects investigation, controlled construction access and specialist trades to resolve difficult site conditions through one accountable partner.
FACING A COMPLEX REPAIR IN AN ACTIVE SITE?

Field Execution
CONTROLLED OPENINGS. REAL FIELD WORK. THE HIDDEN CONDITIONS MADE VISIBLE.
Protected wall openings exposed the concealed services. Specialist removal and replacement addressed the damaged piping, with testing and sealed penetrations completing the repair sequence.

Retained finishes protected as access was created.

Targeted removal inside the opened wall.

Ceiling and wall access connected the investigation to concealed services.
