kcICON Bridge Nears Completion

November 2, 2010 Robert Thompson

Paul received a few photos of the kcICON bridge that are just too cool not to share. These were sent to him by Massman Construction. These were taken in September of this year. MoDOT’s Flicker album of the dedication ceremony is here. The new bridge was dedicated and partially opened to traffic (southbound) on September 27th. The northbound traffic was shifted to the new structure on October 22nd. All of the bridges and ramps for the project will be opened by the end of the year – 6 months ahead of schedule. Can’t wait to see it after the exisitng bridge is demoloshed, though it is a pretty cool image with the old and new bridges together. Updates for the project are on the project Facebook Page.

DBA on team for New Hastings, MN Bridge

August 30, 2010 Robert Thompson

The Lunda/Ames design-build joint venture (Lunda Construction Company of Black River Falls, Wisconsin and Ames Construction, Inc. of Burnsville, Minnesota) has been awarded a contract to build the new Highway 61 Hastings Bridge over the Mississippi River in Hastings, Minnesota. Parsons Transportation Group is the designer and DBA is performing geotechnical design of the bridge foundations and settlement mitigation as a sub-consultant to PTG.

Here is the existing bridge that is being replaced (viewing from upstream):

In addition to several relatively large approach spans, the new bridge will include a 545ft long free-standing arch main span with four lanes of traffic and a 12 foot wide common use pedestrian/bike path. The new bridge will allow additional parking and an artistic plaza area south of the river. An anti-icing system will be installed to help achieve the 100-year design life.

On the south side of the Mississippi River, the bridge foundations will consist of spread footings bearing on dolostone bedrock. The remaining bridge foundations will utilize 42in diameter pipe piles. Several Statnamic load tests, both axial and lateral, will be performed by our friends at AFT.

Settlement mitigation is required beneath the North Embankment due to several relatively thick and deep strata of compressible fine-grained soils. The embankment will also be heavily instrumented to evaluate performance of the embankment and mitigation technique.

Preliminary work including subsurface investigation has begun. The subsurface investigation is being performed by Braun Intertec under sub-contract to DBA. Test piles will be installed in early September, 2010 with subsequent load testing soon after.

The awarded design-build contract is for $120M. The estimated project completion date is May 13, 2013.

Bridge updates – kcICON, Audubon, Beck Street

May 25, 2010 Robert Thompson

As geotechnical/foundation engineers, we don’t usually get to see much of what happens on a project after the foundations are completed, especially a project like a large bridge that can take years to complete. Technology such as the Internet, webcams, and digital photography have made it easy for us to see how things are progressing on projects, as well as maybe get images of the completed structure. As I have noted before, some projects are using Twitter and Facebook to keep the public informed on closures, delays or overall project progress as part of good public relations. Her are some updates on a few of our recent projects.

kcICON:

The main span is well underway, including the cables. The kcICON Facebook page is here.

Audubon Bridge:

Check out the webcam. You can download images if you like. YOu can also do a time-lapse from Day 1 of construction.

Beck Street Bridge:

Part of the I-15 Express Link project in Salt Lake City, UT. The photos below I obtained from the photos page on the project web site . We were involved in the design and construction of the foundations for the Beck Street Bridge only.

Artistic Construction Photo Contest – Volume 1

May 10, 2010 Robert Thompson

With all of us visiting construction projects across the country, occasionally we take a photo that appears to be somewhat “artistic” – maybe the lighting (or lack of), or the aspect. I have assembled a few such photos submitted by DBA engineers in the first installment of the DBA Artistic Construction Photo Contest. Included in this installment are such items as: “Daybreak on Night Shift at JJA” and “Fountain” by S. Dapp, the series “Evolution” by P. Axtell, “GI Rig at Sunset” by T. Siegel, and “Piles in the Mist” by R. Thompson. This first volume has more photos of mine than others, but we’ll work on better balance in future volumes.

Feel free to “vote” for your favorite in the comments. I’ll try to update periodically as we have more “worthy” photos!

kcICON Bond Bridge Article in Deep Foundations Magazine

May 4, 2010 Robert Thompson

The Spring 2010 issue of Deep Foundations from the Deep Foundations Institute includes an article by Dan and Paul (with a little help from yours truly!). The article is based on our paper presented by Dan at the 34th DFI Conference on Deep Foundations last October in Kansas City.

The kcICON project continues to roll along. Check out their Facebook page where they have lots of photos and links to their YouTube page. They recently completed the widest bridge deck pour ever for MoDOT.

Audubon Bridge Update – Piers out of the water!

February 25, 2010 Robert Thompson

It has been a little while since we last visited the John James Audubon Bridge site in New roads, Louisiana. My how things have changed! I just have a couple of pictures of the piers from January – it is really looking like a bridge now! For frequent updates, check out the webcam and the photo albums on the project web page. The web cams have a really cool time lapse button that shows you a time lapse loop of the pier from the beginning of construction.

UPDATE (2/28/10) – I added 3 new photos to the slide show that were taken this last week. At that time the piers were at lift 21 and were about elevation +335 feet (the top of the sheet piles at the foundation level are about elevation +50 feet).

DBA on successful St. Louis Bridge team

January 26, 2010 Robert Thompson

DBA is on the successful team that was awarded the contract for the new Mississippi River Bridge in St. Louis, Missouri. The project is a joint project of MoDOT/IDOT with MoDOT being the lead agency. HNTB is the lead bridge designer for the new cable-stayed bridge carrying I-70 over the river. The bridge is one part of a larger project that also includes the Missouri North I-70 Interchange, the Illinois I-70 Connection, and the Illinois Tri-level Exchange.

From the project web site:

The $640 million Mississippi River Bridge project is proceeding through design, with construction scheduled to start in early 2010. The new Mississippi River Bridge is the first bridge built connecting downtown St. Louis and southwestern Illinois in more than 40 years. Currently, the only urban interstate bridge between Illinois and Missouri is the Poplar Street Bridge, known locally as the PSB. The PSB is one of two bridges in the United States that carry three interstates. By relocating one interstate (I-70) from the Poplar Street Bridge to the new Mississippi River Bridge, drivers will experience less congestion, fewer crashes and less unnecessary fuel use.

The new Mississippi River Bridge will be a 1,500 foot cable-stayed bridge across the Mississippi River between Metro East and St. Louis, Missouri. The bridge is two lanes in each direction, but is wide enough to be restriped for three lanes in each direction if traffic volumes warrant and additional funding is secured. In addition, the bridge project includes approaches on the Illinois and Missouri sides to get traffic to the bridge.

The wining contractor team is Massman/Traylor Brothers/Alberici Constructors. DBA’s role was to help prepare an alternate concept for the drilled shaft foundation design which will include load test measurements. We anticipate construction to begin in March with load test shaft.

An overview of the bridge is here. The press release for the award of the main bridge is here.

kcICON project moving along – see it on Facebook and YouTube

January 11, 2010 Robert Thompson

The kcICON project in Kansas City, Missouri is using Facebook and YouTube as a public relations tool. They have recently posted new videos and pictures. The latest video is of demolition of one of the existing approach structures. It is all done for public relations, so the photos and videos are oriented for the general public, showing how the project is moving along, how their tax dollars are being spent, and providing information on lane closures, etc.

The kcICON Facebook page is here. The project website with more photos and a web cam is here. You can also follow the project on Twitter here.

I expect we’ll see more use of Facebook, Twitter, etc. on projects in the future. It appears to be effective, at least for the techno-savy crowd!
