Requirements of Diesel Genset Plant in Building Services

Modern Buildings essentially implement the needs of Diesel Powered Electricity Generation Plant. It would become an integral part of the building the day building occupied by its tenants. Here we look into what are the objectives, specifications, services to be considered for functioning complete Diesel Powered Electricity Generation Plant installed in a commercial Building.

Electrical Grounding or Earthing Conductors in Building Construction

Buried Earth Conductors: PVC insulated copper strip conductors or PVC insulated stranded copper cables with cross-section min 70 mm2 or as per earthing calculation. Earthing Conductors: PVC insulated copper conductor as described in the Specification for the particular application.

Technical Submittals of Electrical Earthing / Grounding Prior Installation

Earthing / Grounding work has to comply with the requirements of General and Technical Conditions of the Project including statutory obligations and regulations. Submittals to be approved by project consultant prior execution of the actual work. Regulations and rules of supply authority also to be considered when preparing the submittals for the local in which installation is being constructed.

Capacitor Banks in Electrical Construction Works

Capacitor banks help to improve the quality of the electrical power and gives us the more efficient operation of the power system. Capacitor banks are inexpensive if we compare the benefits they deliver to overall power system and can be easily installed anywhere on the network. This specification covers the manufacture, supply, installation, testing and commissioning of 415 Volts, 3 phase, 50 HZ, capacitor banks for power factor improvement in building electrification project.

Method of Clean Earthing or Grounding in Electrical System

Clean earth grounding or low noise earth shall be provided as required, to ensure that the level of induced or conducted interference from external sources, including the facility power grounding system, does not produce incidence of malfunction of the equipment, which is unacceptable for the operating system.

Conditions Of Sub-Contract Agreement In Construction

Occasionally Main Contractor of the construction work depends sub-contractor for accomplishing some smaller or part of the project that may require specialized technical know-how and installation methods. In those cases Main contractor selects some sub-contractors who has capacity to achieve the task within the given time frame. Hence both of the parties, ie., Main contractor and Sub-contractor to be signed an agreement which protects both the parties' interest. Here is a sample for Conditions of Sub-contract Agreement in Construction Works.

Lighting Distribution Boards (LDB) In Electrical Construction Works

Lighting Distribution Boards are an integral and essential part of every building project and it must be designed, manufactured and installed all in accordance with the safety standards. In most of the cases it operates a layman wherein others operate dedicated or trained person. This article explains what are the basic and essential standards, parts, frame to be applied for manufacturing and installation of lighting distribution boards in a building project.

Method Statement in Construction Contracts

Every project is unique, in particular, construction projects. There are many methods applied to accomplish functioning of individual installations included in the whole project. Building services like Mechanical, Electric, and Plumbing (MEP) work have given more importance than other disciplines dealt with. It's because of complexity and alternate methods available to accomplish the same output. While executing individual installations - also known as tasks - construction team have to adopt suitable methods submitted as an integral part of Tender. Most of the project managers or representatives of client keen to look Method Statement of critical and important tasks. We will look into what is Method Statement and what is the importance a Method Statement brings to a construction project.

Wiring Materials And Installation Methods in Electrical Construction Works

Electrical wiring needs expertise attention to every building projects. It directly related to the safety of human beings and utilities / equipment people handle. The scope of electrical wiring shall cover supply, installation, testing and commissioning of all conduits and accessories, wiring, switches, socket outlets, junction boxes / pull boxes, GI pull wires, ceiling roses making connections etc. Unless otherwise indicated wiring shall consist of PVC insulated copper conductor wires installed in heavy gauge steel galvanized conduits.

Security and Access Control Systems (SACS) for Critical Security Areas

Special areas like Airports, Port Trusts, Naval Base, Military base, Telecom buildings, Refinery, Petroleum handling areas etc. needed highly sophisticated security and access control system. It provides safety and security for both men and equipment the area handling. Here is the specification and installation methods for SACS.

Construction Shop Drawings

Construction Shop drawings are the actual detail of all manufactured or fabricated items, indicate proper relation to adjoining work, amplify design details of equipment in proper relation to physical spaces in the structure, and incorporate minor changes of design or construction to suit actual conditions.

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.

Electrical Earthing or Grounding Electrode Design for Building Construction

Earthing or Grounding Electrode for an effective and reliable electrical earthing system requires proper survey and analysis of project location, type of structures installed and electrical / electronic equipment used in the entire system. The design calculation of the earth electrode systems shall be based on the approved earth resistivity data and the system's fault currents and their duration.

Low Voltage (LV) Switchgears in Electrical Construction Works

Low Voltage Switchgear are familiar to every people since they are the controlling mediators between low voltage utilities and equipment with human beings. Be it a common home DB or an isolator or control centres, they all are being manufactured to use untrained people ie., common people. The scope of works shall cover the supply installation, testing and commissioning of main and sub-distribution boards, panel boards, fusible safety switches, circuit breakers etc. Associated minor building works require for the erection of the distribution boards and panels shall be included in the scope of work.

 

Mechanical Services In MEP Construction

Particular Specification For Mechanical Services describes various general requirements In MEP Construction Work, a contractor to follow when they start executing but not limited to unforeseen work or requirements to accomplish the whole project contract.

Conduit Wiring In Electrical Construction Contract Works

Scope of Work of this this sample specification covers the supply, installation, testing and commissioning of all wiring materials for power and lighting in concealed and/or surface conduits.

1. Applicable Standards

The conduits shall conform to IS 9537 I & II  or equivalent standards. Switches, Plug Sockets shall conform to IS 3854 and IS 4615, however, contractor shall comply with the latest or superseded versions of IS/BIS to be used for the complete work.

Fire Fighting Services in MEP Construction Contract
