Going Beyond Traditional Fabrication
Posted by Alison Trost on March 10, 2010 at 11:05 AM

AISC and NSBA member Oregon Iron Works, Clackamas, Ore., is looking beyond traditional fabrication tasks and diversifying its capabilities to include manufacturing streetcars. As the first U.S. streetcar manufacturer in six decades Oregon Iron Works already has 13 streetcars on order.

 

The company’s other out-of-the-box productions include manufacturing steel bridge girders, hydroelectric systems, unmanned seaplanes, space-launch platforms, and nuclear-containment equipment. All along, the key to the firm’s success has been its ability to be open minded about green technologies and how they mesh with its capabilities.

 

Oregon Iron Works recently signed on to develop North America’s first commercial ocean wave energy system. Once again, going green has proved to be a good way to overcome the economic downturn: the company is looking to hire 150 or more new employees.

Steel Construction by Hand
Posted by Alison Trost on March 9, 2010 at 10:37 AM

Preserving a historic property in Vancouver, B.C., Canada, was the only viable option for creating a new multi-family town home. In order to keep its existing 5,000-sq.-ft footprint, the structure needed to be a renovation. If the developer chose to demolish and rebuild, zoning requirements would shrink the new building size by half.

The project was also in tight quarters and did not allow for heavy machinery to assist in the renovation. Therefore most of the structural steel skeleton was installed by hand.

Current building codes posed a second obstacle – meeting newer seismic requirements. The solution was to place the entire building on jacks so a new foundation could be could be put into place that would support new steel columns and beams.

The job took about five months to complete by hand, but in the end the historic heritage school is now one of the sturdier buildings in town.

Whip out your pencil and calculate the savings (meanwhile, get ready to set your clocks ahead)
Posted by Tom Klemens on March 8, 2010 at 10:10 AM

For most of the U.S., this is the last week of Standard Time. I've already set my alarm for 2 a.m. next Sunday morning (not really, but it sounds pretty earnest) when we'll "spring ahead" an hour.

 

Funny - just when I've begun to remember to think about which side of the train I should sit on so I don't have the sun in my eyes for the 30-mile trek into the city each morning, I get a reprieve.

 

I usually catch the 6:49 heading southeast into Chicago, and since February 15th that has been increasingly after the sun came up. Just last Wednesday, March 3rd, I stopped momentarily to appreciate a colorful (6:24) sunrise as I was backing out of the driveway. This week I'll continue to carefully choose a seat on the right side of the morning train. Of source, even though next Monday we'll be back to boarding in the dark (for a week), the sun still will rise long before we arrive in town.

If you prefer to dig into it yourself, start with the U.S. Naval Observatory's table of sunrise and sunset times for your locale (they offer times for more than 22,000 locations) by going to http://aa.usno.navy.mil/data/docs/RS_One
Year.php
. And while you're there, take advantage of the curious explanations for things like why the shortest day of the year doesn't coincide with the earliest sunset.

 

Welcome to the sure signs of spring, and remember (most of you) to change your clocks next weekend.

Steel Shots: Net-zero Energy Lab Uses Recycled Steel
Posted by Alison Trost on March 5, 2010 at 11:11 AM

labvideo1.jpg

Haselden Construction (Centennial, Colo.) is building the 219,000 square-foot Research Support Facilities (RSF) building, which is designed to be a model for sustainable, high-performance building design. The design–build team also includes RNL Design, Denver, and Stantec Consulting, which provided engineering, energy modeling and sustainability consulting.

Technology — from sophisticated computer modeling to advanced windows that actually open — will help the newest building at the U.S. Department of Energy's (DOE) National Renewable Energy Laboratory (NREL) near Denver be one of the world's most energy efficient offices. A short video clip (click here to view) shows its construction and explains many of the ways planned to achieve zero net energy use.

 

Although Denver-based structural engineer and builder KL&A is not mentioned by name, the first comment in the video is about its use of reclaimed steel gas pipe as the building columns, and all the action shots are about structure. Steel was provided by AISC member Omaha-based Paxton & Vierling Steel Co.
