When it is possible, firefighters rescue persons endangered by the fire, if necessary, before turning their full attention to putting it out. fire fighting Firefighters, skilled in…
Wondering how to measure your roof to estimate required material for roof replacement? Here the process of measurement of the roof is described through easy steps. Introduction Taking the measurement of the roof is very important work before buying materials for re-roofing. You can save significant money and time by estimating the cost of required…
Although there are many EDM instruments available, there are basically only two methods of measurement employed, namely the pulse method and the more popular phase difference method. Pulse method A short, intensive pulse of radiation is transmitted to a reflector target, which immediately transmits it back, along a parallel path, to the receiver. The measured…

A second method to determine the value of the coefficient of consolidation is to use only the results of a consolidation test for small values of time, and to use the fact that in the beginning of the process its progress is proportional to the square root of time. In this method the measurement data…
Determining the cause of structural failures is the challenging discipline of forensic structural engineering. Determination of civil and criminal liabilities drive many such investigations, but there are also valuable lessons to be learned from these failures. Not So Elementary, My Dear Watson Collecting facts to recreate the scene of a crime has been a fascinating…
Noise pollution is caused by unwanted sounds that intrude into our daily lives. The increasing density in urban planning has made it essential to deal with this problem. Noise is a pollutant that is controllable and is amenable to abatement technology. Standards have been set out by the Environmental Protection Agency which sets the standards…
Special attention during construction is of the utmost importance. Poor construction can result in costs in maintenance and repairs that are greater than the initial costs. Major factors affecting slopes are the intrusion of water and the slope too steep for the soil type. The problem of water intrusion can be minimized by following sound…
The following steps can be used to draw sectional views: Step I: Draw the projections of the given solid in an uncut condition in both the views (the FV and the STY) by thin construction lines. Step II: Draw the cutting plane (or the section plane) as a straight line inclined at B to the XY line…
Underground space is very important for the smooth functioning of society as this is where the pipelines, utilities, waste disposal systems, etc., are located. Trenchless technology allows this space to be used without disrupting the surface. The Need for Trenchless Techniques Utilities required for modern day living need to be laid out in a planned…
