DEFINITIONy Heavymechanical engineering construction is that branch of

construction technology that involves the activities related toplanning ,execution ,and control ofproject (of mechanical nature)to achive some desired goal.

y

Construction of such projects requires knowledge of engineering andmanagement principles and business procedures, economics, andhuman behavior.

y Construction engineers engage in the design of temporarystructures,qualityassurance and qualitycontrol, building and site layout surveys,on site material testing, concrete mix design, cost estimating, planningand scheduling, safetyengineering, materials procurement, and costengineering and budgeting.

Mechanical Engineering ConstructionIn almost all the case of MEC, the project follows

the concept that involve the following agencies :

y Client or Owner of the project

y Concept of Contractor

y Contractor

y PMC (Project Management Consultant)


6/21

Concept of Client

y Client or Owner of the project

It is the organization who proposes the Project. All the

construction related payments is credited to theaccount of client and the project upon completion ishanded over to client for operation purpose. Theprojectproposes is generallyEPC(Engineering,

Procurement & construction) & LSTK( LumpsumTurnkey) Type. Some of the famous clients in india areIOCL, HPCL, NTPC, BHEL, GAIL, SAIL, NHPC, theyoperates in their respective areas.


7/21

Concept of Contractor

yContractorThe role of contractor is to carryout detailedengineering, project management, projectexecution & commissioning related activities.Contractor Organization have to be project based.The project is awarded byOwner to anycontractoror to consortium after carrying out normal

tendering process, considering techno commercialviabilityof contractor for the project concerned.Some of the reputated contractors are L & T,Punjlloyd Ltd., DLF, Gammon.


8/21

Concept of PMC(ProjectManagement Consultant)

yPMC (Project Management Consultant)The role of PMC is to give consultancyservices to Clientfor getting the project done. Some of the reputatedPMC's are EIL, Mecon Ltd etc. It depends upon theClient wheather he would employsome PMC's or not.


9/21

Concept of Consultants

yEngineering Consultants

It is solelyat the discretion of Contractor that hewould employsome other engineering consultantsto provide technical services to the contractor.


10/21

Concept of SubcontractorsySubcontractors

The contractor maysubcontract the whole or inparts the various packages ofproject to variousother small subcontractors. a prior approval has tobe taken from owner for employing some other

subcontractor.

Common MECs Projects :yThermal Power Plant

yGas Based Power Plant

yConstruction of Pipeline

yConstruction of Piping & plumbing

y

Construction of RefineriesyPre -Engineered Buildings


12/21

Thermal Power Plantsy Rankine cycle based steam power plants are the major source ofpower

generation.

y In a thermal power plant, the chemical energystored in fossil fuels such as coal,

fuel oil etc is converted successivelyinto thermal energy, mechanical energyand finallyelectrical energyfor continuous use and distribution across a widegeographic area. In the Rankine cycle, high pressure and high temperaturesteam raised in a boiler is expanded through a steam turbine that drives anelectric generator.

14/21

Gas Based Power Planty The gas based power plant used combustor in place ofboiler( boiler is used in case of thermal fossil fuel basedpower plant).

y Examples :

y Anta Rajasthan 413

y Auraiya Uttar Pradesh 652

y Kawas Gujarat 645

y

Dadri Uttar Pradesh 1307y Jhanor Gujarat 648

y Rajiv Gandhi Kerala 350

y Faridabad Haryana 430 Total 4445


15/21

Construction of Pipeline

y Oil & Gas Pipeline involves the construction of undergroundpipeline to facilitate the transportation of oil & gas from onelocation to another desire location. The pipeline maybe for citygas distribution, for cross countrytransportation purpose, for

water transportation or for transportation of some special desireproduct.HSAWpipes of varying dia range maybe used and

welded together along the route ofpipeline and finallyloweredin the excavated earth.


16/21

Construction of Pipingy Piping is done at the pipeline stations to alter theproperties of f lowing fluid.

yThe components used in piping are : Flanges

Valves

Weldolets/Sockolets

T joints Small Pipe


17/21

Construction of Plumbingy Plumbing is same as piping but done for all thepurposes other that oil & gas & realated fluids.


18/21

Wind Power Plant

A wind farm is a group ofwind turbines in the

same location used for production ofelectric

power. Individual turbines areinterconnected

with a medium voltage (usually 34.5 kV)

power collectionsystem and communications

network. At a substation, this medium-voltage

electrical current isincreasedinvoltage with a

transformerfor connection to the high voltage

transmissionsystem.. A wind farm may be located off-shore to take

advantage ofstrong winds blowing over the

surface of an ocean or lake.


19/21

Hydroelectricity PlantHydroelectricity iselectricity generated by

hydropower,i.e., the production ofelectrical

power through the use of the gravitational

force of falling or flowing water. It is the most

widely used form ofrenewableenergy. Oncea hydroelectric complexis constructed, the

project producesno direct waste, and has a

considerably lower output level of the

greenhouse gas carbondioxide (CO2

) than

fossil fuel poweredenergy plants.. This was

approximately 20% of the world'selectricity,

and accounted for about 88% ofelectricity

from renewablesources.

Heavy Equipments Used In Construtional Field

y Dozers

y Excavators

y Motor Graders

y

Scrapersy Tractor/ Loaders/ Backhoes

y Track Loaders

y Wheel Loaders

y Other Earthmoving Equipments


21/21

y Heavy equipment refers to heavy-dutyvehicles, specially

designed for executing constructions tasks, mostfrequently, ones involving earth moving. Theyare alsoknown as construction equipment, earth movers,engineering vehicles, or just plain equipment. Through themechanical advantage of a simple machine, the ratiobetween input force applied and force exerted ismultiplied. Currentlymost equipment use hydraulics as aprimarysource of transferring power.
