Daniel Boone Bridge Replacement

September 3rd, 2014

Boone Bridge from BozFrom March to November 2013, Geotechnology, Inc. performed work on the Daniel Boone Bridge, which carries Interstate 64 across the Missouri River, joining the counties of St. Louis and St. Charles, Missouri.

Geotechnology was selected to perform the work due to their responsiveness, expertise and safety record. In its’ 30-year history, Geotechnology has successfully completed numerous near-water and over-water projects, including the recently opened Stan Musial Veterans Memorial Bridge which spans the Mississippi River at downtown St. Louis.

The Daniel Boone project includes replacement of the 1930’s era westbound bridge with the construction of a new bridge over the Missouri River. Foundation inspection holes were drilled within the footprint of each drilled shaft to confirm the rock quality below the bearing surface of each drilled pier (i.e. end bearing design).

The project presented a few challenges to the crews drilling through more than 100’ of alluvial deposits consisting of clays, silts, sands and cobbles that were in close proximity to operating vibratory caisson rigs installing large-diameter steel casings to the top of rock. Drilling for the riverine shafts was done from a contractor-provided elevated platform over the Missouri River and over fully excavated drilled shafts with unsupported span lengths of up to 12’. Because the rig could only be moved from pier to pier by a crane working from a spud barge, the team had to use a small, light-weight, skid mounted drill rig. The mast heights and inability to hoist equipment further than 15’ at a stretch added to the time required to perform the work.

To facilitate bedrock coring using NQ-sized tools, the contractor assembled 4 inch heavy wall pipe in welded sections and lowered that assembly into the 8-12 foot diameter steel casings. The casings were set to the apparent top of bedrock ranging from 80–112 feet below the working platform. Extreme lengths of unsupported casings caused bowing and twisting which added another layer of complexity to the project.P1000373

Geotechnology, Inc. completed the land borings using their CME 85 truck-mounted rig and CME 55HT truck-mounted rig and Rig Source, Inc. provided the skid-mounted Diedrich D50 for the overwater portion of the project.

In total, the project required the installation of 42 Foundation Inspection Holes, consisting of 1,950 feet of rotary drilling and 903 feet of NQ2 Rock Coring and 444 rig hours on-site. Geotechnology’s work was completed without accident or injury.

St. Louis Drilling Group Marks Safety Milestone

September 14th, 2010

On Tuesday, September 14, 2010, the Geotechnology St. Louis Drilling Group attained 1,000 workdays without a loss-time accident. This amounts to over 141,000 man hours worked.

“I’m very proud of this achievement, particularly because of the inherent risks associated with drilling,” said John Bostwick, R.G., Geotechnology’s St. Louis Drilling Group Manager. “It’s also a testament to the success of Geotechnology’s company-wide safety program.”

Geotechnology takes a multi-pronged approach to managing safety, including:

  • Safety Training
  • Enhanced Safety Incentive Program
  • Revitalized Safety Team
  • Increased Safety Observations
  • Enhanced Communication

This approach successfully contributed to a more than 60% decrease from 2008 to the present in the company’s OSHA recordable incident rate.

8 Ideas to Help With Project Efficiency…from your Geoprofessional

June 10th, 2010

Staying on budget and on schedule while maintaining quality is the challenge and goal of every project, but the reality is that there are speed bumps and unknowns. We want to help reduce those situations or provide knowledge in helping to resolve them as they relate to geotechnical, environmental, drilling and testing services. We’ve included a handful of ideas that we’ve culled from both lessons learned and successful implementation. We’d love to discuss them with you to see if we can be of assistance in planning a successful project.

1.  Conduct an environmental audit of existing operations at the planning stage to assure expansion plans are environmentally compliant and to avoid fines and negative public relations.

2.  Reliable estimates are possible with adequate design and schedule information. When early preliminary budgets are based upon assumptions, commit to revisiting those estimates and provide appropriate contingencies.

3.  Review the testing budget and scope with the project team. Careful planning increases the team’s understanding of the project requirements and assures that observations and tests are conducted in a timely and efficient manner.

4.  When conducting environmental assessments, assess all potential issues that could impact future development. Issues that may be omitted from the list but could be important include mold, lead paint, wetlands, floodplains and endangered habitat.

5.  Consider lump sum contracts and evaluate them to see if they would be a good fit for the project.

6.  Consider pre-drilling pier holes to reduce schedule and budget risk, better define quantity of rock removal and enhance safety.

7.  Ask for regular tracking of fees at certain milestones. Periodically update estimate of final costs.

8.  Negotiate scope and fee with geotechnical, environmental and materials testing consultants. Through negotiation, a scope and fee can be established that is just right for your project. Procuring these services through a low bid process only encourages a low initial fee. A negotiated scope and fee development focuses more on the total project cost implications of the recommendations made by your foundation and environmental consultants, which are much more significant than the consulting fee.

Geotechnology Wins ACEC Missouri Grand Award for Subsurface Utility Engineering Project

February 6th, 2008

The American Council of Engineering Companies of Missouri awarded Geotechnology a 2008 Engineering Excellence Grand Award for its project entry, “Subsurface Utility Engineering for 226 Bridges.” As part of their Safe and Sound Bridge Improvement Program, MoDOT contracted Geotechnology to perform subsurface utility engineering to locate and map utilities around 226 bridges within 20 counties in Northwest Missouri. Geotechnology designed and executed a protocol to quickly and efficiently accomplish site research, SUE Quality Level B geophysical surveying, land surveying and drawing preparation for each of the remote bridge locations during harsh winter weather. MoDOT required a total of 226 utility drawings and supporting field notes a mere 70 days after project launch. Geotechnology completed the project within schedule parameters as well as under budget. MoDOT was able to use the utility maps in the project bidding process, which resulted in more accurate, competitive bids and possible reduction of costs for future design and construction. This project approach provides a framework for future SUE services on large, time-sensitive design-build projects.
