When environmental concerns are discovered during a project, the immediate reaction is often that the contamination itself is creating the cost.
In many cases, however, the environmental condition may have existed for years or even decades.
What frequently increases project costs is not the contamination itself—it is the timing of the discovery.
Environmental issues identified early can often be incorporated into acquisition decisions, project design, permitting, budgeting, and construction planning. The same issues identified later may create delays, change orders, additional mobilizations, and unexpected expenses.
The difference is often not the severity of the issue. The difference is the number of options available when it is discovered.
1. Project Schedules Become Compressed
Environmental investigation takes time.
Additional soil borings, groundwater monitoring, laboratory analysis, regulatory coordination, and data evaluation may all require weeks or months to complete.
When environmental concerns are identified early, these activities can often be incorporated into the overall project schedule.
When concerns are identified shortly before acquisition, financing, permitting, or construction, project teams may be forced to make important decisions under significant time pressure.
The environmental work may be the same. The schedule impact is not.
2. Previously Unknown Underground Storage Tanks
One common example involves undocumented underground storage tanks (USTs).
A property may have a long history of industrial or commercial use, but historical due diligence may not fully identify the presence of former tanks.
During redevelopment activities, contractors encounter previously unknown tanks and associated petroleum-impacted soil.
The project may then require:
- Tank removal
- Additional environmental investigation
- Soil characterization
- Regulatory notifications
- Supplemental excavation
In addition to environmental costs, projects may experience:
- Construction delays
- Contractor standby charges
- Remobilization expenses
- Extended carrying costs
The tanks may have been present for decades. The cost increase occurs because they were discovered after important project decisions had already been made.
3. Soil Management and Disposal Planning
Many redevelopment projects require excavation.
When soil is characterized early, project teams can evaluate:
- On-site reuse opportunities
- Off-site disposal options
- Transportation requirements
- Facility acceptance criteria
- Project budgets
Early characterization often provides flexibility and predictability.
When soil conditions are not evaluated until excavation begins, project teams may find themselves making disposal decisions in real time while equipment and contractors remain onsite.
The result is often increased cost and schedule uncertainty.
4. Groundwater Impacts and Construction Activities
Groundwater impacts can create additional challenges when discovered after redevelopment planning is underway.
In some cases, groundwater contamination may require:
- Additional investigation
- Delineation of impacts
- Monitoring wells
- Regulatory coordination
- Remediation planning
Groundwater can also affect construction activities.
For example, excavation and foundation work may require dewatering. If contaminated groundwater is encountered, treatment may be required before discharge.
Additional requirements may include:
- Temporary treatment system design
- Permit applications and approvals
- Sampling and monitoring
- Equipment mobilization
- Treatment and disposal costs
These requirements can significantly affect both project schedules and budgets if they are not identified during the planning stages.
5. Regulatory Strategies Become More Limited
Environmental regulations often provide multiple paths for addressing contamination.
When environmental issues are identified early, project teams typically have more time to evaluate:
- Remediation alternatives
- Risk-based approaches
- Redevelopment objectives
- Regulatory programs
- Long-term property use considerations
When issues are discovered later, project teams may have fewer options and less time to evaluate them.
This often results in reactive decision-making rather than strategic planning.
Practical Questions to Ask Early
When environmental concerns are identified, consider the following:
- What decisions depend on the results?
- How could the issue affect redevelopment plans?
- Will future construction limit remediation options?
- Are permits or regulatory approvals likely to be required?
- What information is needed to develop realistic project budgets and schedules?
These questions often help identify potential challenges before they become project delays.
Final Thoughts
Environmental issues do not necessarily become expensive because contamination is severe.
More often, costs increase because uncertainty remains unresolved until after important acquisition, design, financing, permitting, or construction decisions have already been made.
Early environmental investigation does not eliminate risk. It creates options.
And in many projects, having more options is what ultimately controls cost, schedule, and outcome.
