Pre-Acquisition Site Assessment（PAA)
WESSLING provides data-driven pre-acquisition site assessments—integrating current contamination status with geological conditions to reveal the true value beneath the surface, ensuring that every investment is made with confidence.
When acquiring a site, the greatest risks are often hidden underground. Historical soil contamination, unfavorable geological conditions, or underground obstacles can all lead to massive remediation costs, lengthy construction delays, or even legal disputes after the transaction is completed.
WESSLING’s pre-acquisition site assessment service deeply integrates site contamination investigations with geological surveys to provide you with a one-stop environmental and geotechnical due diligence solution. We don’t just tell you whether the site is “clean”; we also help you determine whether the foundation is “reliable.” This dual-pronged approach ensures that risks are fully accounted for in your financial projections.

WESSLING addresses the following key challenges for you:
- Quantifying Environmental Liability: Is there soil or groundwater contamination? What is the budget required for remediation?
- Preliminary Assessment of Development Feasibility: What is the geological bearing capacity? Are there any adverse geological formations that could affect pile foundation construction?
- Negotiating leverage: Use objective data to support discount negotiations or avoid non-performing assets.
Dimension 1: Site Contamination Investigation — Identifying Risks to Human Health and the Environment
- Phase I (ESA Phase I): Identify potential sources of contamination (such as former chemical plants, gas stations, etc.) and assess the likelihood of contamination through historical imagery, government records, and interviews with relevant personnel.
- Phase II (ESA Phase II): Develop a detailed sampling plan to collect soil and groundwater samples through drilling and well construction, and test for key parameters such as heavy metals, volatile organic compounds, and total petroleum hydrocarbons at an independent accredited laboratory.
- Risk Assessment: We assess the extent of contamination in accordance with national and local standards. If contamination is detected, we will estimate the scope of remediation required so that you are aware of the “worst-case scenario” before setting a price for the transaction.
The national overall soil contamination rate is 16.1%
36.3% of monitoring sites at heavily polluting enterprises exceeded standards
The rate of soil cadmium contamination exceeds standards by 7.0%
Dimension 2: Site Geological Survey — Laying a Solid Foundation for Development and Construction
- Geotechnical Investigation: Determining the bearing capacity and deformation parameters of soil layers through drilling, cone penetration testing (CPT), and standard penetration testing.
- Geological hazard detection: Identify potential weak layers, backfilled pits, voids, or liquefiable soil layers.
- Groundwater and Seismic Effects: Determine the groundwater level and its corrosiveness, evaluate the seismic effects at the site, and provide a basis for the seismic design of buildings.

Dimension 3: Integrated Delivery Value
During the delivery phase, you’ll receive not just a set of data, but a clear, actionable report to guide your decision-making. By overlaying environmental risk maps with geological models, we provide a comprehensive assessment of the site’s suitability for development and its hidden holding costs.
Our Core Strengths
- “One-Stop Service”: We have dedicated teams for both environmental surveys and geotechnical engineering, eliminating the coordination gaps and information silos that often arise when working with multiple consultants. Using a single site map, we can simultaneously plan environmental sampling and geotechnical investigations, significantly shortening the assessment timeline.
- Certified Laboratories Ensure Accurate Data: We operate in-house laboratories certified to international standards such as ISO 17025. Every step of the process—from sampling to the issuance of analytical reports—is strictly controlled, ensuring the accuracy, credibility, and traceability of our test data. This directly supports your investment decisions and any subsequent legal proceedings.
- Flexible and efficient execution: Our service schedule is closely aligned with your trading schedule to ensure that key milestones are met on time.
- A Sustainable Decision-Making Perspective: We don’t just focus on immediate risks; we take a full lifecycle approach to assess a site’s potential for sustainable future operations, helping you make informed choices that balance commercial returns with environmental responsibility.
