EVstudio participated in Milender White’s golf charity event at Fox Hollow Golf Club.  We are happy to be a part of a charity that raised over $30,000 for various children charities.  Unfortunately, our team of Greg Arbour with KLG, Carl Boone and Justin Boone with CandL Development and Jim Houlette with EVstudio came in last place and earned the ‘OOPS’ prize.  But we had a great time and we look forward to next year!

New Openings in Existing Concrete Double T Wall at Evergreen Mercantile

August 21, 2009

On August 18, the removal of the 2″ concrete flanges of the concrete double T wall began.  EVstudio engineered the front wall to allow for the new openings and provided details to adequately brace the structure with the remaining wall lengths.  When construction is completed you won’t be able to tell this was once a double T wall building with the typical visible flanges.


How To Read Metric Rebar Marks on Steel Reinforcing

August 20, 2009

In order to identify the basic information about the rebar that is delivered to a jobsite, it is important to know how to read the mill markings that are stamped on every bar. This is especially critical to ensuring that your materials match up with the specifications in the plans.

These mill markings illustrate the “soft metric” system adopted by CRSI member mills in 1997 (see our post about metric and imperial markings):

The top letter or symbol identifies the producing mill and deformation pattern.

The next marking is the bar size.

The third marking symbol designates the manufacturing material — usually either “S” for carbon-steel (ASTM A615) or “W” for low-alloy steel (ASTM A706).

Finally, there will be a grade marking (4 or 5, for 420 or 520) or by the addition of one line (420) or two lines (520) that must be at least five deformations long.

Trusses Go Up at Kershenstein’s Honka Log Home

On Sunday I stopped by the Kershenstein residence to see what progress has taken place. Along with the upper floor framing and upper framed walls, the upper level trusses look to be almost all in place. Also on the lower level, temporary bracing is in place until the stone clad concrete masonry columns are built to support the main level deck above.


Differences in Metric and Imperial Reinforcing Bar (Rebar) Grades and Sizes

August 17, 2009

All Contractors should be intimately familiar with Steel Reinforcing Bar (Rebar) grades and sizes. With materials coming from all over the globe these days, it is ever important to know the comparison between the Imperial and Metric systems for bar grading and sizing. Starting in 1997, CRSI member steel mills have adopted new “soft metric” standards in their grading and sizing. 

The charts below should be used to cross reference imperial grades and sizes with metric grades and sizes. Watch out because if your specs are in metric and your supplier is still using the imperial system, you may wind up with some really huge bar diameters on site. As you can see, the old #4 (1/2″) bars are now being called out as #13, so be very careful here to avoid these kinds of potentially costly mistakes.

Soft Metric Bar Sizes vs. Inch-Pound Bar Sizes:
