Structural Programs for Modular Construction

We are a mobile modular and component manufacturer that has been using an aggregate of programs (Autocad, Strucalc, WoodWorks, and excel) to complete our designs from start to finish. We are in the process of making some changes in how we are doing things so we are looking at options on our structural packages also.

We have purchased Revit and will soon be doing the bulk of our designs in BIM. In addition, the above structural programs are due for updating and I’m not positive we wish to stick with them as I know there are many other structural programs out there that take a more holistic approach to the design. At the moment I use my own spreadsheet to analyze structure forces and then use Strucalc and Woodworks to analyze the individual members.

The industry we are in is extremely fast paced... to give you an idea we just completed a 21 module complex (18,061 sq. ft.) design build in less than 2.5 months here at the factory. Most projects are complete in 2.5 weeks from design to built (not including state tags and approval). The majority of the buildings we complete are wood but we also do some steel or wood\steel combinations. Most of the buildings we do are single story anywhere from 1500-5000 square feet, however, as discussed above we have done some 18,000 square feet or more buildings also and whatever we get should be able to do multiple stories.

In particular I have been looking at Risa3d and RAM but am concerned as to how well they model wood structures (in the past it appears they didn't do this well) and if building these models will take too long or be worth it for our industry. In the future when we are actively doing Revit I could possibly even steal the model from BIM if the option is available. If not and I could reuse old models and quickly change the size of the buildings that may help in the long run (that is often what we do with CAD now, we literally have 100's of previous floor plans to pick and go from).

I have also looked at Tedd's and enercalc as replacements for what we currently have but these programs fall more in line with what we currently do.

In general we are looking for some info on what direction those that have used some of these programs would do. If what I’m doing is probably most efficient so be it... I’ll probably go with Tedd's or Enercalc (or if someone knows something better then please say so). However if I could use one of the model programs efficiently in this industry I would prefer that as it would combine much of what I do but if it is too much work and I couldn't reuse old designs or transfer from revit it may not be worth it. What are your thoughts?

If you defined the design process and it is repeatable - you might consider writing your own software.

Many packages offer too much - but not enough of what you really do or want. You can even buy third party packages that will allow you to tie into your code and output completed AutoCad drawings and files.

This is basically what we have done and continue to do. There is always some young college kid out there that would love to practice his VB.Net skills for $15 /hr.

Kind of how I got started actually - 35 years ago!!
 
Thanks Mike for the Reply.

I had thought of this myself and it would be a good solution but very time consuming to say the least. I code a bit myself and an undertaking such as this would take months of someone’s time and cost significantly more than some of the programs available already. I also think I would be fairly skeptical of any program that was used for such a broad array of Engineering calculations (wind, seismic, snow, member calcs., etc.) that did not have a supportive engineering community behind it helping the developers find bugs\issues with the code. I would be the community... and as much as I would like to say I could effectively test\oversee a project such as this and catch all the issues that may arise... I just don't think I have the time or sheer determination to make that happen :).

I personally would like to choose one of the mature packages available and was seeing if anyone who has used some of the existing packages felt they could fill our needs.
 
I feel your pain - it would be quite an undertaking. But we have decided that it is worth it - as there may be a few hundred people using the final product. And by automating the "modelling" process - we will save thousands of man-hours. And could you imagine trying to teach a bunch of non-engineers AutoCad or RISA!!

BTW - even the best software suppliers make mistakes. Make sure you keep updating.
