Importance of Fire Alarm System

Fire alarm systems have become increasingly sophisticated and functionally more capable and reliable in recent years. They are designed to fulfill two general requirements: protection of property and assets and protection of life. As a result of state and local codes, the life-safety aspect of fire protection has become a major factor in the last two decades.

Methods of Installing External, Exterior and Outdoor Lighting System

Installation Methods of External, Exterior and Outdoor Lighting System includes lighting equipment luminaires, control gears, panel boards, poles, brackets, cabling, and allied minor civil works. All installations are to be carried out under strict supervision of qualified supervisors and engineers. If installation required heavy vehicles, extreme care has to be taken for preventing damages of lighting equipment, control gears and poles.

Engineering Drawing / Drafting

Drawing means lines, shapes, finishes, sizes and colour combined to construct objects or structures. It will be a cumbersome task when narrating an idea without drawing, if the idea is an object or structure. Engineering is heavily depending on drawings, since, technical drawing has developed a global language named Engineering Drawing, capable to express its objects and structure to everyone without the barrier of human languages. Engineering Drawings conveniently helps to explain and record an idea that can be smoothly conveyed to one person to other or sometimes to machine too.

General Questions And Answers In Engineering and Technology

What Is Engineering? Engineering is an art of applying science to the optimum conversion of the resources of nature to the uses of humankind. It is based principally on physics, chemistry, and mathematics and their extensions into materials science, solid and fluid mechanics, thermodynamics, transfer and rate processes, and systems analysis. It is thus we must define Engineering: "the practical application of science and math to commerce or industry". In other words "the art or science of applying scientific knowledge to practical problems".

Emergency Power Diesel Generating Set In Electrical Construction

This article covers the manufacture, supply, installation, testing and commissioning of 415 volts, 3 ph, 4 wire, Diesel Alternator Set (Diesel Genset). The set shall be mounted on common base frame and complete in all respects including the auxiliary equipment such as battery auxiliary, lube oil pumps, filters, oil storage tank, centrifuge, etc. including piping required for interconnection between the set and the auxiliaries which are mounted separately.

The contractor shall coordinate with the other services (trades) involved in the project to insure that the foundation, are suitable for the equipment to be installed.

Hoisting Facilities in Construction Site Logistics

The Hoisting and Craneage Plan shall include a layout for all hoist/crane infrastructures. The Plot Developer should consider all detailed information such as hoist arrangements, platforms, loading deck, mast sections, hoist equipment, details of attachment to building, gates, fences, safety devices, overload protection, etc.

Quality Plan for Construction Projects

It is essential that services and systems in a building construction contract work are provided to conform to the requirements of the customer, and that the activities be effected as economically as practical. The achievement of these objectives is facilitated by setting up working procedures and practices, which collectively provide a “Work Efficient”, yet controlled operating environment. It is the purpose of this Construction Quality Plan to give instruction to personnel, on the implementation of the company system such that the above objectives are accomplished. Documentation specific to the project will be provided to ensure full compliance with the particular requirements of the contract.

Vacuum Interrupter (VI) for Vacuum Circuit Breakers (VCB)

Vacuum Interrupter (VI) are vacuum sealed-off devices incorporated in Vacuum Circuit Breakers (VCB) to cause interruption of fault currents in medium voltage electrical distribution systems. The contacts of the VI are pressed against each other under normal circuit conditions. In the event of a fault current, the VCB mechanism effects withdrawal of the movable contact from the fixed contact.
