Integrate Project Management into Your Projects
At the engineering firm I founded, we've recently seen an increase in RFP's (Requests For Proposal) that include project management as a consultant selection criteria, in one form or another. Not just as a "nice to have" criteria, but as one of the scores that factor in the selection of....
Best Civil Engineering Firms to Work For
Every year, CE News publishes the "Best Civil Engineering Firms to Work For." Since the award began in 2001, hundreds of outstanding civil engineering firms have received the award. Being on the list attracts good employees and good clients. Results are obtained from a survey of the employees by CE....
Difference between Pound-Force and Pound-Mass
In the SI (metric) system of units, kilograms are used for mass, and newtons for weight. There is no confusion as the units are different. However, in the US system, pounds are used for both mass and weight. Confusing? You didn't think it was going to be easy did you? To....
How to Calculate Void Ratio
The void ratio is the ratio of the volume of voids (open spaces, i.e. air and water) in a soil to volume of solids. $$e = \frac{V_v}{V_s}\newline\newline =\frac{V_g + V_w}{V_s}$$ Where: e = Void Ratio Vv = Volume of voids (m3 or ft3) Vs = Volume of solids (m3 or....
The Experts Speak Out: Another Engineer’s Perspective
Recently I watched the latest documentary, called The Experts Speak Out, from the 911 Truth Movement. Truthers, as they are called, believe that there is evidence that the World Trade Center buildings were most likely brought down by controlled demolition rather than weakness from the airplane's impact. Apparently over 2,100....

Business Management Client Management Project Management Business Management As a manager, you're responsible for making the business grow (or not grow!). This means you need to track....
What is the Torsion Constant?
In structural steel design, the Torsion Constant, J, represents the ability of the steel beam to resist torsion, i.e. twisting. It's units are mm4 or inches4. Equation The bending resistance formula, in which the torsional constant is used, is: $$\theta = \frac{T\cdot L}{G\cdot J}$$ Where: θ = Angle of Twist....
