pRE-BID GEOLOGICAL RISK ANALYSIS
Every civil foundation contract comes accompanied with varying degrees of geotechnical information. There are inherent risks to every rock type and there are inherent risks to every operation. Understanding the interaction between the two is where Dukelabs DSC Inc can assist your estimating teams and Handoff meetings.
We're able to review your pre-bid geotechnical documentation and identify risks based on the rock type and activity methodology / tooling.
boring reports and analysis
Dukelabs DSC offers detailed boring analysis for any stage of your project.
We're able to identify lithologies and common risks associated with your work type. Just from borings, we can initiate a Potential Change Order that could have otherwise went unnoticed as anything other than slowed production. To a hammer, everything's a nail.
I.e.: Graphitic schists are a sub-unit in New York City's complex metamorphic rock terrain. It will crush into a waxy powder when using a down-the-hole hammer. This disables the hammers from creating the proper cuttings to be flushed out of the hole. In this situation you would be on the lookout for a differing site condition, initiate your notification to the owner within your contract's specification, and begin start discussions with the EIC. If no response is given on how to proceed, you need to protect your own interests and track and submit your time to be negotiated at a later date. In most situations this would just be identified as slowed production. What we see is a contractor that lost a percentage of their profit due to no fault of their own.
Tunnel & shaft as-built mapping
As-built documents provide a detailed and precise representation of the geological conditions. They are essential for capturing any material changes from the initial plans that may have occurred during the construction process. These documents are required for future reference, maintenance, and record-keeping.
Understanding the pre-bid geotechnical contract documents is pivotal for forming a reasonable expectation of ground conditions, and therefore forming a bid.
Dukelabs DSC specializes in familiarizing ourselves with your pre-bid documents, identifying variations from reasonable expectations in the field, analyzing a cost impact, and submitting Differing Site Condition proposals on your behalf.
From Notification to Negotiation.
petrographic analysis
Petrographic analysis is a specialized scientific examination and characterization of rock and mineral samples through the use of advanced microscopy and analytical techniques. This detailed study provides invaluable insights into the mineralogical composition, texture, structure, and origins of geological materials, contributing to a deeper understanding of Earth's history, natural resources, and various industrial applications.
The same macro structures that are impacting your project exist as micro-crystalline structures as well. We use petrographic techniques as another tool in justifying material changes to reasonable bid expectations.
