The Domino Effect: How One Construction Mistake Can Become a Much Bigger Problem

A construction mistake doesn't always stay on the construction site.

Sometimes, a single mistake can affect an entire system.

On September 21, 2026, a construction crew working near the rail lines in New Brunswick, New Jersey, reportedly severed a major fiber-optic line. According to reporting from WTVB, the resulting communications disruption contributed to significant flight disruptions across parts of the East Coast, affecting airports including Newark, JFK, LaGuardia, Philadelphia, and Boston.

The incident is a powerful reminder of something every construction owner should understand:

There is no such thing as an isolated construction decision.

Every project exists within a larger network of utilities, infrastructure, businesses, tenants, customers, municipalities, and surrounding properties.

One mistake can create a domino effect.

A Construction Site Is Part of a Larger System

When you look at an active construction site, it's easy to focus on what is immediately visible.

The building.

The excavation.

The equipment.

The workers.

The plans.

But underneath and around that site can be an enormous network of infrastructure that isn't visible from the surface.

Fiber-optic lines.

Electrical systems.

Gas lines.

Water.

Sewer.

Telecommunications.

Transportation infrastructure.

And in many commercial and real estate projects, these systems are critical to the surrounding community and businesses.

That means construction risk extends well beyond the walls of the building being constructed.

The Problem With Calling Something a "Small Mistake"

Imagine a project team discovering an unidentified utility line in the path of planned excavation.

It might be tempting to think:

"We'll figure it out."

But that decision can have consequences.

If the utility isn't properly identified, the excavation may be delayed.

If the information isn't communicated to the entire team, another crew may unknowingly work in the same area.

If the location is incorrect on the drawings, the problem can repeat itself.

And if an active utility is damaged, the consequences can extend far beyond the project.

The cost isn't necessarily limited to repairing the damaged line.

There may be project delays, emergency response costs, business interruption, contractual consequences, regulatory issues, reputational damage and possibly death. 

The original mistake may have been small.

The consequences may not be.

Due Diligence Happens Before the Excavator Arrives

One of the most important lessons for owners is that construction risk management begins long before physical construction.

Before excavation starts, the project team should understand what is beneath and around the site.

That can include reviewing available utility records, coordinating with utility providers, confirming markings, understanding site conditions, and using appropriate subsurface utility engineering when the project warrants it.

The exact requirements depend on the site, jurisdiction, project scope, and type of work being performed.

But the principle is consistent:

Know what you're working around before you start digging.

Checking a box on a preconstruction checklist is not the same thing as actively managing the risk.

The Importance of Subsurface Utility Engineering

Subsurface Utility Engineering, commonly referred to as SUE, is one tool used to improve understanding of underground utilities.

Instead of relying exclusively on existing records or assumptions, SUE can help project teams investigate and document underground infrastructure using established investigation and mapping methods.

That information can become particularly valuable during design and preconstruction.

It can help the team identify conflicts before construction begins rather than discovering them when an excavator is already in the ground.

And that distinction matters.

Finding a conflict during design gives the team options.

Finding it during excavation creates pressure.

The Owner Needs Someone Watching the Bigger Picture

Contractors have an important responsibility for safely executing their work.

Engineers have responsibilities related to design.

Utility companies have responsibilities related to their infrastructure.

Municipalities have their own requirements.

But the owner also needs someone looking at the project as a whole.

That is one of the important roles of an Owner's Representative.

The Owner's Representative can help coordinate the various parties involved in the project and ask questions that might otherwise fall between organizational boundaries.

Have utilities been properly investigated?

Are known conflicts reflected in the design?

Has the appropriate information been communicated to the contractor?

Are site conditions consistent with what the project team expected?

What happens if they aren't?

These questions are not about slowing down construction.

They are about preventing avoidable disruption.

Risk Management Is More Than Safety

When people hear "construction risk," they often think about worker safety.

Safety is obviously critical.

But owners also need to consider operational and financial risk.

A utility strike can potentially affect:

Schedule: Work may stop while the damage is assessed and repaired.

Budget: Emergency repairs, redesign, additional labor, and other costs can accumulate quickly.

Operations: A damaged utility can affect businesses, tenants, transportation, communications, or other services.

Liability: Depending on the circumstances, multiple parties may become involved in determining responsibility.

Reputation: Owners and project teams can face difficult conversations when construction activities disrupt surrounding operations.

The larger the project, the more important this broader view becomes.

Small Decisions Create Large Outcomes

This is not just a story about underground utilities.

It is a lesson about construction management.

A missed coordination meeting can delay a decision.

A delayed decision can affect procurement.

A procurement delay can affect installation.

A late installation can affect inspections.

A missed inspection can affect the opening date.

The same domino effect happens with budgets.

A small scope gap can become a change order.

A change order can consume contingency.

Reduced contingency can leave the owner exposed to the next unexpected condition.

Construction is interconnected.

That is why experienced project leadership focuses on the relationships between decisions, not just the decisions themselves.

Oversight Is an Investment

Owners sometimes look at project oversight as another cost.

But effective oversight is designed to protect a much larger investment.

The purpose isn't to have another person standing around a job site.

It is to have someone helping connect the dots.

Someone reviewing the big picture.

Someone following up.

Someone asking questions before problems become emergencies.

Someone making sure the information provided by one member of the project team reaches the people who need it.

That is where proactive project management creates value.

The Best Problem Is the One You Never Have to Solve

Construction will always involve uncertainty.

Existing conditions can surprise you.

Materials can be delayed.

Designs can change.

Markets can move.

Unexpected conditions will happen.

The objective isn't to pretend risk can be eliminated.

It is to identify foreseeable risks early enough to do something about them.

The New Jersey incident is a useful reminder that the consequences of construction decisions can extend much farther than the job site itself.

A line on a drawing can represent critical infrastructure.

A mark on the ground can represent an entire system.

And a decision made in the field can have consequences far beyond the project fence.

Protect the Project Before Construction Begins

At MD Advising Group, we believe effective Owner's Representation starts before construction begins.

That means understanding the site, coordinating the project team, identifying risks, reviewing assumptions, and making sure owners have the information they need to make informed decisions.

Because protecting a construction project isn't just about managing what happens after something goes wrong.

It's about creating the conditions that make avoidable problems less likely to happen in the first place.

If you're planning a commercial, medical, dental, or real estate development project, let's discuss the risks before they become expensive problems.
