    Typical Residential Construction in South Africa

    I have a friend planning to move from Arizona, US to South Africa. She has had preliminary plans drawn and expects to have a local Architect finish them when she moves over... the economy is cause for delay. I am from the Pacific Northwest and while I don't like to be presumptuous, I expect...

    1982 UBC standard

    I have an interesting project in front of me... I have to verify that an existing structure, built in the early 80's, was constructed to the 1982 UBC in force at the time. Any advice on strategy?

    Theft

    I just spent this Sunday afternoon filling out a police report identifying the items stolen from an office break in. In all honesty, our greatest loss appears to be from the lack of frequent off site backup. Computers and servers can be replaced, information can't. The police have asked for...

    I have a soldier pile wall with W12x40 (ASTM A992) retaining a maximum of 7 ft. Because this wall will be permanent, I have been asked to provide protection against corrosion. I have always understood that corrosion of steel embedded in soil is negligible (unless ph of soil is really low)...

    Active Vs Passive

    For many this is a dead horse, my apologies. I was recently provided a geotech report which stated that as long as the wall was allowed to deflect (0.002 x Height), then the active pressure may be used in lieu of the at-rest pressure provided. They go on to suggest that near the corners...

    Electronic Signature

    As a practice, we "electronically" stamp our drawings with the following process. I have asked a number of other professionals and so far very little has been said. I'm considering talking to the board but thought I would stop here first. My question to you, in your opinion do you feel we...

    Deflections under Seismic Load Effects

    With regards to the seismic load combinations utilizing the overstrength factor (ASCE7-05 section 12.4.3), I am trying to find guidance on appropriate deflection limits. I suppose there are two classifications of response, 1) Code referenced and 2) Sound Engineering judgement. 1) I'm not...
