    Liability of designing dorm lofted beds

    I think an engineer's liability on designing a bed is not nearly the same as a furniture company designing it, building it, and selling it. Part of the pricing of the bed is the cost of defending lawsuits, knowing there will be claims, settlements, and possibly a few large awards. You...

    Can't get rid of the imageframes

    You have to turn the imageframe varible off. At the command prompt (I work on 2004 so I hope the command prompt still exists in 2009), type imageframe, and turn it off. Keep in mind, with imageframe off, you cannot select the image to move it around or change its properties. To do that, turn...

    Horizontal sliding doors

    A manual or powered sliding door may be allowed, if it is not part of the means of egress. Doors in a corridor may require latching if the corridor is to be smoke protected and/or fire rated. It is very difficult to look at one door without the context of the entire building. Don Phillips...

    Good Structural E-library?

    A star for sliderulera for just maintaining his library. There are a few free magazine that I subscribe to that have pdf's on thier website to easily archive those articles in case the website goes away. Structure Magazine quickly comes to mind as an excellent resource at a fantastic price...

    Strip Footing Required Reinforcement

    I try to avoid placing reinforcing in footings unless needed as well, otherwise beginning with the 2005 National Electrical Code, you have to bond this reinforcing to the building's grounding system. Don Phillips http://worthingtonengineering.com

    Budgetary Pricing for Change Orders et. al.

    I am comfused. If the change orders are for a receontly completed project, why not just look at the material bills to get the unit prices? Don Phillips http://worthingtonengineering.com

    Older National Electric Codes

    Even if the drawings have the code edition information on it, that may not have been the code in effect at the time of application for a permit. Don Phillips http://worthingtonengineering.com

    Fire Pump Phase Reversal

    I think the electriicans call this "bumping the motor" to check the phasing. Don Phillips http://worthingtonengineering.com

    Are capillary breaks really needed if there is a vapor barrier?

    The vapor retarder, when coupled with a pipe below the retarder and vented to the outside, is intended to create a path for the radon gas to be passively vented and reduce the amount of radon getting into a basement. The next step, if the radon level is in excess of 4 picocuries per liter, is...

    Starting Up A Design Office

    I would agree, manofstl. I was lucky to pick up some CAD with a former employer and still use that skill from time to time. I think kids that use software saw they are proficient. Don Phillips http://worthingtonengineering.com

    Professional Liability Insurance

    You can get, what I think is called "a tail policy" to cover your current liabilities into the future. You can ask your broker about it. If you were practicing like 20 or 30 years and wanted piece of mind in retirement, it may be worth purchasing this sort of coverage. Don Phillips...

    Metal Roof Waterproof Materials

    And depending on the size of the building, its construction type, occupancy, and location from the property line and/or other buildings, it will influence which roofing system is permitted. Not to mention the pitch of the roof. Don Phillips http://worthingtonengineering.com

    Structural analysis of communications tower

    Assuming the zoning will be handled by the homeowner, I would start with the building code. These would be covered in Section 3108, which refers to Chapter 16 and ASCE 7 for determining seismic and wind loads. It would also be designed to TIA/EIA-222. Those referenced standards would be a good...

    Construction in the Gulf region (GCC)

    Sounds like goverment strings for lots (billions) of federal dollar to fix up the Gulf Coast (must...resist...googling...gcc....). Don Phillips http://worthingtonengineering.com

    Starting Up A Design Office

    I have a friend who's firm says no but he does a little on the side. I am sure he knows he is subject to dismissal if his supervisor finds out. Hence the ethical question. If you do something against company policy, on your own time, not using company resources, nor competing with the...
