SAFETYWHAT ?

• Difficult to define due to its inter -relatedness with several factors.

• Anything devoid of accident is SAFE.• “ A thing is provisionally categorized as safe if its

risks are deemed known and,the light of that knowledge, judged to be acceptable”

• Safety is inversely proportional to accident rate. High Rate lower the safety And vice-versa.

• Safety comes from common sense . To build a safe working environment an engineer have to be SMART. Where SMART stands for-

• S = Seriousness• M = Meritorious• A = Aim• R = Responsibility• T = Time bound

WHY?• Below chart showing the parameters,

which are related to the safety of an organization. As safety is related to many variable parameters, so safety is an important and primary criteria at the construction sites. From some previous year record hundreds of fatal injuries to workers in construction sites took place due to lack of safety awareness. Construction safety is required to reduce tangible and intangible losses.

MATERIAL MANAGEMENT

Material Management is the function responsible for the coordination of planning, sourcing, purchasing, moving, storing and controlling materials in an optimum manner so as to a pre-decided service to the customer at a minimum cost.

Whenever construction work begins, a lot of resources are needed. Initially a list of raw materials and machineries are prepared. For procurement of raw materials quotations &sample are being taken from three or four parties and they talk about the external party takes some time and gives a rate chart including VAT, tax etc. The party which provides the minimum is chosen but they should be an authenticated one. In this way the store works along with the purchase dept. Machineries are being planned arranged and provided to the construction site by the cos-corporate office. Sometimes hiring is being made to fulfill the requirement.

Store is responsible for the receiving, storing and issuing of raw materials, machineries and all kinds of equipment to be used at the construction site. Providing the necessary facilities and services to support successful completion of project is sometimes overlooked or put low on the priority list when bidding or setting up a project. Basically the store department is in the control of receiving or issuing, quantity, proper store, quality and maintaining records and accounting of items.

PLANNING

A construction project must be completed according to design and specification for the quality and serviceability purpose. But a perfectly completed project may become wastage, if it is not completed within scheduled time or contract duration. As the time directly proportioned to the money, a great car should be taken on the execution time scheduling. A good planning of work can increase the profitability. This planning of work is prepared by the planning department team under the guidance of Project manager. The work of this department starts at the very beginning of the commencement of a project after getting the structural and architectural drawing. There are some tasks done by the planning department is

SYSTEM FORMWORK

• Shuttering is formwork for the concrete casting of the structural elements. Shuttering can be vertical or horizontal as per requirement. Shuttering can be done by wood or steel formwork depending upon the availability of material and cost. For RCC shuttering more care should be taken for formwork. It is a temporary arrangement and it requires to hold the concrete up to certain period for gaining adequate strength of the concrete.

• CODE : IS : 456 – 2000 (Indian Standard) shall be referred to prepare shuttering concrete casting.

THE 4 KEY ADVANTAGES OF ALUMINUM FORMWORKS :

1. ENVIRONMENTAL FRIENDLY2. SHORTEN THE CONSTRUCTION

PERIOD3. CIVILIZED CONSTRUCTION4. REDUCE COSTS

SURVEY & LEVELLING• Survey is the primary work for a building

project. There are various types of survey in general. Among them first land survey has to be accomplish after selecting the project site. This land survey may includes measurement of land area, level of the project site land etc. According to the report of the survey team designer can proceed to design the buildings or structures. As total structural design of a structure depends on the survey report, so Survey an most important job for construction.

• LAND MEASUREMENT• LAND LEVELLINGINSTRUMENTS USED :• TOTAL STATION• AUTO LEVEL

DEFFERENT WORKS DONE BY SURVEY:• Preparing contour map of the land where

structure will be constructed,• Level checking for shuttering,• Level marking on Each floor,• Level marking on vertical reinforcement for

shuttering job.• Placing of grid line etc

PLANT AND MACHINERY• TOWER CRANE• CONCRETE PUMP• BACK HOE LOADER• CONCRETE BATCHING PLANT• TRANSIT MIXER• BAR BENDING MACHINE• BAR CUTTING MACHINE• DIESEL GENERATOR

QUALITY CONTROL

Quality is the most important agenda for production of any type of product. In construction site quality of the material, work and maintenance should be kept properly. There is a separate department to maintain quality of the constructional production. this department is named as Quality Control Department. This department is responsible for all the materials being delivered on the site.

Any material which is supplied to site is first check by an authorized person from quality department. It is also responsibility of this department to check whether the construction work is going on properly according to specified manner or not.

MATERIALS WHOSE QUALITY IS TO BE CONTROLLED CONCRETE: CEMENT: FINE AGGREGATE: COARSE AGGREGATE CHEMICAL ADMIXTURES

TESTS FOR CONCRETE

SLUMP TEST• AIM: To determine the workability of fresh

concrete.

CHARACTERISTIC COMPRESSIVE STRENGTH TEST

• AIM: To determine the characteristic compressive strength of concrete.

SITE EXECUTIONThis project “Elita Garden Vista” is mainly divided into two phases. In which phase I is completed and

phase II work is going on. Under phase II, Block 6,7,8,9,10,11,12,13 construction is to be conducted.

SITE EXECUTIONBLOCK 11 BLOCK 10

CONCLUSION

• Vocational training is a part of our MAKAUT –WB curriculum. But after getting this 30 days vocational training at “Elita garden vista” under Simplex Infrastructures Limited, it was not just a vocational training for University syllabus to us. This training gives a lot of technical knowledge, which will help us to build our carrier. This session introduced us with a work friendly, safe environment, and gives us lot of opportunities to build technical knowledge on modern construction techniques. • Apart from technical knowledge we are grateful enough to the engineers who shared

their work experience with us. There are a lot of things which cannot be learnt from any books or institution but an exposure to such a construction site can only provide. Such construction site related essential terms and knowledge of work will help us throughout our work life.• In conclusion We would like to thanks again Simplex Infrastructures Limited for giving

us this opportunity and we look forward to working with this company in the near future.
