pRE-BID GEOLOGICAL RISK ANALYSIS
Each civil foundation project carries unique geological risks due to variations in rock types and soil conditions. These risks can significantly impact operations, from tooling requirements to timeline adjustments. At Dukelabs DSC Inc., we bridge the gap between geological complexities and project planning, helping your estimating teams and project managers understand and prepare for site-specific conditions.
Our team can review your pre-bid geotechnical documentation to identify potential risks based on rock type, tooling methods, and activity requirements. This proactive approach reduces uncertainty, supports accurate bidding, and promotes smoother project handoffs.
boring reports and analysis
Dukelabs DSC Inc. provides comprehensive boring analyses to identify lithologies and potential risks associated with each work stage. By examining borings, we can pinpoint factors that may impact productivity and suggest a Potential Change Order (PCO) if conditions differ significantly from expectations.
For example, graphitic schists in New York City’s metamorphic rock terrain can disintegrate into a fine powder when drilled with a down-the-hole hammer, leading to challenges in flushing cuttings. In such cases, Dukelabs DSC Inc. advises immediate reporting to the Engineer in Charge (EIC) to document the differing site condition and initiate timely discussions for adjustments. This protects the interests of both contractors and clients by ensuring that risks are addressed proactively, minimizing production delays and unplanned costs.
Tunnel & shaft as-built mapping
As-built documentation offers a precise record of geological conditions encountered during construction, capturing any material changes from the initial plans. These records are essential for long-term maintenance, reference, and compliance.
At Dukelabs DSC Inc., we provide expert interpretation of pre-bid geotechnical documents, forming a solid basis for establishing realistic ground condition expectations. By identifying variations from the expected site conditions in real-time, we help mitigate risks and assist in preparing Differing Site Condition proposals to address cost impacts effectively.
From Notification to Negotiation, Dukelabs DSC Inc. supports your project at every stage of documentation and response.
petrographic analysis
Petrographic analysis involves a detailed examination of rock and mineral samples using advanced microscopy and analytical methods. This in-depth study reveals mineral composition, texture, and structural details, providing insights into the geological history and material properties critical to your project.
At Dukelabs DSC Inc., we use petrographic analysis as a powerful tool to support material justification and ensure alignment with bid expectations. Understanding both macro and microcrystalline structures helps us identify factors that could impact performance, making this analysis essential for reliable material assessments.
