Value Engineering and Its Importance In Engineering Industry

Value Engineering VE

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.

Refrigeration Plant in MEP Construction

Refrigeration Plant in MEP Construction Work
In this sample MEP specification section, Mechanical Refrigeration Plant has been described in detail under construction contract work. Main Highlights of this MEP Specification are: General Requirements, Compressors, Evaporators, Condensers, Condensing Units, Refrigeration Plant Accessories, Pipework, Valves and Ancillaries, Insulation, and Controls.

Electrical Earthing or Grounding For Metallic Fencing

Electrical Earthing or Grounding For Metallic Fencing
In the electrical point of view and as a safety measure, metallic fence shall be separately earthed unless they come within 1.8 m of any equipment or structure above the surface of the ground, which is connected to the main earthing system. If the separation of 1.8 m cannot be obtained the fence shall be bonded to the earthing system. Here is how compound fences connecting to the earthing system.

Engineering Drawing / Drafting

Engineering Drawing and Drafting - Representative image
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.

Methods of Installing External, Exterior and Outdoor Lighting System

External or Exterior 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.

General Conditions And Requirements in Electrical Construction Contract

Electrical Construction Contract Drawing
A sample Specification for Electrical Construction Contract Works that describes General Conditions And Requirements to accomplish electrical works all in conjunction with Architectural, Civil, Mechanical and other services. All electrical equipment, materials, installation and workmanship shall comply with the latest edition of the applicable codes and standards of any of these organization listed below:

Automatic Transfer Switch (ATS) OR Automatic Mains Failure (AMF) Panel
