HOLDING TO ELECTRICAL SPECIFICATIONS

2009-02-06T19:08:00.004+03:00

Engineers should maintain their positions on electrical system design, whether for code issues, good design practice- or the owner’s best interest "Why on earth did you design it that way?" This is a plaint often heard from the contractor, construction manager, or owner when documents are issued for construction. More often than not, the statement is liberally littered with modifying expletives.

PRICE AND COST ANALYSIS

2009-02-06T18:20:00.002+03:00

Some form of price or cost analysis should be performed in connection with every procurement action, regardless of whether the organization is a vendor or a subrecipient. The form and degree of analysis, however, are dependent on the particular subcontract or purchase, and the pricing situation. Determination of pricereasonableness through price or cost analysis is required even though the

SPEED OF "ELECTRICITY"

2008-08-19T16:31:00.005+03:00

How fast does electricity flow? Well, it depends on what you mean by "electricity." The word Electricity has more than one contradictory meaning, so before we can talk about its flow, we have to decide on which of several "electricities" we really mean. OK, then how about this. When we turn on a flashlight, something called an "electric current" begins to happen. Inside the flashlight bulb, the

The Speed Of Electricity

2008-08-19T16:28:00.001+03:00

We are told, by physicists, that electricity travels the same exact speed, through a wire, that light travels through a vacuum (the famous speed c). There are two problems with that, aren't there?Electricity is the flow of electrons. Electrons have mass. Relativity says that things with mass cannot travel at the speed c. Only things with no mass (zero rest mass) can (and must) travel at c. Even

PROJECT MANAGEMENT

2008-08-18T15:58:00.004+03:00

A successful project starts with solid planning and ends with a smooth hand-off…The phrases “on time” and “within budget” are often used in discussions of project delivery, but how often can they actually be used to describe a project? Project schedules can fall apart for any number of reasons, but it's often a case of poor planning and a lack of communication. And if participants have uncommon
