Getting into the Details

Modern Steel Construction

Feb 2008


This article should have been an opportunity to inform on real and serious problems that plague our industries future. But, you chose to run an extended advertisement for Tekla and Design Data. Two 3D modeling programs that lend little to the overall solutions.

Your article argues that 3D modeling software can allow someone to competently do his/her task with only two years experience. Having twenty years experience and acutely aware of the industries problems,  I argue that the lack of draftsmen in this field has nothing to do with a software package they may use and that there is no way a 2 year understudy could do a project competently.


And here is why:

Lack of information from the architect and engineer is increasingly becoming a detriment to “on time completion” this is the biggest problem. (This is exactly what BIM is supposed to solve) There is currently no software in the world that can figure out how something was suppose to appear or should have been noted on the contract drawings. Information takes time and education to deliver, and this is not happening, because of this, there is no way a 2 year understudy can competently address these situations with so little experience, they would not have enough experience to know how it was supposed to be built.

No matter what software package I use in my office, the actual problem of missing or incorrect information provided to me is still unresolved. This program cannot create RFI responses and will not attend the production meetings that consume so much of a detailers time. Your guests contend that with their BIM technology, these problems will go away.


BIM explained:       &nbs
p;     (Our Company has no experience with Design Data)

BIM  is Building In Model, not steel in model; Actual BIM drawings are electronic files that originate at the designing architect, and then sent to the engineer who supports the structure using preferred materials. This file set is sent on to the General Contractor who would provide them to me to locate steel and provide details for fabrication, all still in the same BIM set. Once completed, the plumbers, HVAC, electricians even the interior designers get them, so they can locate their materials avoiding the steel, concrete and each other. Once completed this one file set will contain every piece of the building, if it’s done correctly - assembly is a dream.

Your guests have used a ton of really intelligent statements to make the argument that they are the answer, but in reality Tekla, has nothing to do with BIM, this program is simply a stand alone isolated 3D modeling program.

Great article.  However, I had a question about the tables.


What does the X represent and the number next to it?  Thanks
