Of Bridges, Biofuels, and Buildings (Engineering Excellence Awards)

As I noted earlier this week, the ACEC of North Carolina’s Engineering Excellence Awards gala was held last month. 13 amazing projects were awarded recognition, including projects involving environmental and coastal issues, higher education facilities, and government projects.

Each project was important, unique, or challenging in some manner. In my next post, I will highlight one of the most unusual– the Swine Farm Biogas project by Withers & Ravenel.  In the meantime, here are all of the winners, which I’ve loosely sorted into categories:

Mingo Creek Trail Bridge

Mingo Creek Trail Bridge

Coastal & Environmental projects

The Karen Beasley Sea Turtle Rescue and Rehabilitation Center, Surf City, NC (Cavanaugh & Associates)

Sea Bright to Manasquan Profile Survey, NJ (McKim & Creed)

American Tobacco Trail Pedestrian Bridge, Durham, NC (Parsons Brinckerhoff)

Mingo Creek Trail, Knightdale, NC (Stewart)

Town of Hillsborough Riverwalk, Hillsborough, NC (Summit Design and Engineering Services)

Swine Farms Biogas Renewable Energy Project, Bladenboro, NC (Withers & Ravenel)

 

Marsico Hall at UNC

Marsico Hall at UNC

Campus & Higher Education projects

South Halls Renovation, Penn State, University Park, PA (Clark Nexsen)

Science & Technology Building, Fayetteville State University, Fayetteville, NC (McKim & Creed)

Marsico Hall, University of North Carolina, Chapel Hill, NC (Mulkey Engineers & Consultants)

Military, Municipal, & Highway projects

Infantry Squad Battle Course, Marine Corps Base Camp Lejeune, Jacksonville, NC (Catlin Engineers and Scientists)

Carolina Field of Honor War Memorial, Kernersville, NC (Woolpert)

Broad Avenue Bus Terminal, High Point, NC (Mulkey Engineers & Consultants)

NC DOT Land Application of Concrete Byproducts, NC (S&ME)

The diversity of the award-winning projects was very clear, as even a cursory review of the projects demonstrates.  I recommend you follow the links to the specific projects to see some great photos and hear more about the projects in detail.

In the meantime, tell me what project you would have given the “best in show” award to if you were the judge.  Or, was a project left out of the awards that you thought superior to some of these?  Share your thoughts about both these projects, and any others that you think should have made the cut, in the comments section.

Bats, Water, Soil, and Bridges- an Engineer’s dream

Want to know how bats may effect your engineering plans?  Want to hear about cool new bridges?  Read on.

Over the past month, I’ve had the pleasure of attending two events hosted by the North Carolina Chapter of the ACEC (American Council of Engineering Companies).  The first of these was the Joint Transportation Conference, held in conjunction with the NC DOT.  The second was the annual ACEC Engineering Excellence Awards.  At both events, I learned interesting information that engineers should know. Today, I will discuss the Transportation Conference, including some new regulations and unusual design methods.  I will save the highlights from the Excellence Awards for later this week.

Northern Long-eared Bat

Northern Long-Eared Bat

  1.   It’s a cave, it’s a bat, it’s bats, man!     Did you know that your future bridge project may be effected by the Northern Long-Eared Bat?  It’s true.  Right now, the federal government is considering listing the bat on the Endangered Species List, due to the 98-99% mortality rate the bats are experiencing due to “white nose syndrome”. Over 1,700 projects in North Carolina could be impacted, including work on bridges, culverts, abandoned buildings, and guardrails–essentially, any activity involving tree clearing, structure demolition/removal, or structure maintenance. On November 26th, 2014, the US Fish and Wildlife Service extended the comment period to discuss the implications of listing the bat on the endangered species list. If the bat is listed, there is no grandfathering of projects.  All projects will immediately be required to engage in protective activities. Stay tuned, but be aware that your transportation projects could be effected starting sometime next year.

 

2.  Is that a pirate on your map or is it worse–soil contamination? 

known and possible soil contamination

known and possible soil contamination

At the conference, we also heard from the GeoEnvironmental Section of NC DOT on their geologic symbols for known or potential contamination. Known contamination consists of soil or ground water samples that have been analyzed; or by evidence of such contamination as cracked transformers, battery casings, unusual odors while excavating, or new anecdotal information about past use. Potential contamination, in contrast, is for areas where there is no data, but historical maps or photos which indicate current or assumed past uses of possible contamination, such as gas stations, dry cleaner facilities, auto body facilities, chemical manufacturers, landfills, and manufacturing plants. Both known and potential contamination sites are important for designers, as they consider:

  • large cuts, drainage, utilities, or stream relocations in contaminated areas
  • selecting chemical resistant construction materials
  • additional costs for materials, remediation
  • other unanticipated costs or complications

 

highway stormwater program     3.  Water, water everywhere!  We also heard what’s new with the Highway Stormwater Program, including the updated Post-Construction Stormwater Program and the companion Stormwater BMP Toolbox manual. To learn more about these programs, check out:

  • The NCDOT Stormwater website, which contains useful links; and
  • The Highway Stormwater youtube chancel of training videos, which is still in development but will include environmental sensitivity maps, nutrient load accounting tools, and stormwater management plans.

 

Dragon Bridge

Dragon Bridge

4.  Cool, cool bridges  One of the highlights of the conference was hearing about some truly unique bridge designs, including:

  • The Tappan Zee Hudson River Crossing, in New York, featuring twin-tower cable stayed structures and all electronic toll collection
  • Vietnam’s Dragon Bridge, a truly working piece of art; and
  • The Milton-Madison Bridge Slide, (Indiana/Kentucky) the longest bridge slide in North America.  The Milton-Madison Bridge Slide was  a feat of engineering design.  Using “truss sliding” a new 2,427 foot long truss was moved along steel rails and plates and “slid” into place atop the existing, rehabilitated, bridge piers.

 

What about you?  Did you attend the conference?  If so, what insight did you take away?  Share in the comments, below.
