Engineering and Technology

Engineering and Technologies are, in the first instance, simply extensions of the human body, allowing us to overcome the physical limitations with which we are born, and to adapt the natural environment to our own needs. Technologies are inventions of humans that have allowed us to survive, and have enabled our cultures to advance. They are for the most part material objects: tools, for example, are simply detachable additions to the body, the manufacture of which generally distinguishes humans from animals.

Typical Mounting Details Of Fire Alarm Break Glass Manual Call Point

These drawings show how to install Fire Alarm Break Glass (BG) or Manual Call Point (MCP) on walls. It has to be mounted on back box installed in the wall. This box (embedded or exposed as specified in the concerned section of the specification) has to be connected through GI / PVC conduit that will have the Firetuff or equivalent cable to be looped for other detectors. Conduit end to be taken out of the wall above false ceiling to allow the Firetuff cable to be clipped on soffit of the slab.

Drawing below shows how to install Manual call point break glass along with a sounder

In this typical drawing, manual call point break glass unit has been shown as concealed  and the rest  are surface installed in the false ceiling. Sounder has been mounted on ceiling but can also be mounted on wall visibly as per the project specification.

Installation of Audio Intercom System For Building Project

Audio Intercom System being used in high-rise buildings or commercial complexes, provide two way communication from entrances, gates, go-downs, industrial plant rooms and normal doors, to an internal audio handset. It can be used to screen authorized visitors from outside entrance and useful to communicate internally between persons from one room to another room or office spaces. It can also be used to function as effective public announcement system.

Medium Voltage Cables (MV Cables) In Electrical Construction

The contractor shall supply, install, test and commission the 13.8 KV cable network as shown and indicated on the contract documents. Conductor sizes shall be metric as shown, conductor sizes with cross sectional areas smaller than specified will not be accepted. The cable installation shall include all trench work, sleeves, ducts, and all necessary fixings and cable terminations at both ends of the cable. The contractor shall supply and install cable marker posts to indicate the route of all underground cables. Markers shall be provided at every bend along the route and at sites of crossing roads or pipe lines.

Value Engineering and Its Importance In Engineering Industry

The value is a function of cost. Therefore, it can be increased either by improving the function or reducing cost. The maximum value is achieved when the function performs reliably at the lowest cost. A key principle of value engineering that basic functions be preserved and not reduced as a result of improvements in value. Thus Value Engineering (VE) is a systematic method to improve the "value" of goods, products or services through an examination of the function.
