1. INTRODUCTION

ABOUT PRIMAVERA SOFTWARE

The original company’s name was primavera system and established in 1993 by Joel Kopple- men and Dick Faris in Philadelphia, USA. In 1988 software system started to develop in a server-based approach that allows primavera to act as a portfolio system. This is split into two version of software one is stand-alone versionusedforsmallprojects,thesecondisenterprise portfolio system this allows primavera to use throughout organizations to manage the projects. In 2008, Oracle brought primavera and turned into primavera Global Business unit. Primavera P6’s is the world’s largest Pharmaceutical, oil and gas, refinery infrastructureclientsandengineeringsuppliers.

ABOUT CONVENTIONAL BUILDING

Conventional construction method is an ordinary or a standard construction. It involves utility of traditional materials, and remains with a specific-parameters. Most of the conventional buildings are based on plans and measurements, as well as floor plans. While prefabricated construction needs less time same dependability as convectional construction. The advantage of conventional construction is that causes notwobuildingtobesameeachbuildingisconstructed individuallydesignedfromthegroundup.Conventional

buildings have more durability than a prefabricated building.

ABOUT PREFABRICATED BUILDING

Prefabricated building is a prefab building that is manufactured and constructed using prefabrication. It is factory made components that will be transported and assembledonsiteforabuilding.Buildingsarebuiltandin one place and can be reassembled in another place this wastrueformobileactivities.EliminaCastlethefirstslave from west Africa was the first European to build first prefabricated building. The world’s first prefabricated, precast panelled apartment blocks were pioneered in live pool.

1.2 LITERATURE REVIEW

Themainpurposeistostudyanddetermineconstraintsin adopting prefabrication in construction industry. To find the different methodology in both construction and to conclude which construction is best. Conventional constructionisoldmethodandprefabricatedconstruction isnewone.Wecanfindmanybuildingsareprefabricated.

In this paper they have considered G+7 to estimate the quantities of conventional building and prefabricated building. Estimation of quantities is done to find requirement of materials for both conventional and prefabricated. Hear both are considered and estimated how much quantity of materials needed for the construction. Project duration is also main important for completion of the project. Conventional building needs more time compare to prefabricated buildings. Cost analysis is determined by considering the resource, materials, labour and machineries. By considering these factors we can come to cost factor of both constructions. Datacollectionisalsomostimportantinproject.Fromthis

2.1. WORK BREAKDOWN

Work breakdown structure in primavera, in work breakdown structure works are divided into smaller parts or components. Work breakdown structure is key project that is deliverable to team’s work to the manageable section. In work breakdown structure it provides the brief information about the project, by seeing the work breakdown structure can understand the project. Breaking down the work and making them in parts and allotting to the different department to procced the work. By breaking down the work load it willbeeasytodothework

2.1. Project Calendar

Calendars are used to make our work easy; calendar defines the workdays and workhours available in a day. In calendars we can add holidays like government holidays, festivals, if works are not present on those particular days in calendar. We can establish our own calendar according to our company’s work, we can assignresourcesandactivityoncalendars.

According to us and our work. Based on calendar resource will come to site before we should order the itemssothatitdeliversonthedaywhich wementioned onthecalendar.

2.3. RESOURCE ALLOCATION

In primavera resource allocation of resource is important, for each activity which are the resource neededandwhichtypeofengineersneededtocomplete that particular task. Resource includes equipment, labours that are used for construction, these resources are based on the time and they are used in between activities. Creation of resource will be use full in the project and it makes work easy while construction. In primaverawecanaddtheresourcesiftheyarenotthere in the list, we can add units of the resource and we can add price of the resource which will be used for the

construction.

2.4. GANTT CHART

Gantt chat is a tool or a basic tool, it represents the

graphical representation of the project. By using Gantt chat we can understand the work easily, it is graphical representation of schedule, activity and time. From primavera software we can plan start and finish dates and chat will represent the dates according to our activities. In this we can add which colour we want to understand our activity, we can add bars, we can make settingsaccordingtoourchoice.

4. RESULTS

By comparing conventional building and prefabricated building we can know that prefabricated building will be constructed in lesser time, but conventional building needs moretime.

Prefabricated building needs less materials as comparedtoconventionalbuilding.

Table-3: EstimationtimeofConventionalBuilding

When we compare cost of both buildings the cost of prefabricated building is 77,50,000 and conventionalbuildingis64,00,000.

As we compare cost of prefabricated and conventional buildings, prefabricated building costmorethanaconventionalbuilding.Byusing primavera software when we compare the days conventional building needs more days as compared to prefabricated building. The cost of prefabricated building is more due to structural steel and equipment cost is more manpower is used less and machinery work will be more in prefabricatedbuilding.

Table-4: EstimationtimeofPrefabricatedBuilding Cost Estimation Graph

Conventional building is traditional type of construction where it needs more man power, morematerials,needsmoretimebutcostisless ascomparedtoprefabricatedbuilding.

Inboththeconstructiontypesdifferenttypesof activitiesareaddednotsimilartype.

Foreachactivitytimeanddatesareprovidedso that the work completes within the time of scheduling.

The lifespan of both buildings is comparatively same.

The approximately budget made for the two buildings based on the planning and scheduling oftheproject.

If we have more time and budget amount then we can go for the conventional type of construction or else if we have less time and more budget then we can go for prefabricated typeofconstruction.

6. CONCLUSION

From the project we can know that by using primavera software it’s easy to plan and schedule theproject.

Primavera helps us to estimate the project time, cost,materialsandlaboursusedforconstruction.

Consideringtwobuildingsinprimaverascheduling and planning and assigning the resources, there are two types of resources materials and labours wecanassigntheresourcesaccordingtoouruse.

The activity needs which kind of materials or equipment by considering that we can assign the resource.

Primavera software helps us to save time and manage the project in proper way in the constructionofaproject

By using primavera software, we can understand thecriticalpaththathelpsustoidentifythecritical activityandwecandoitinabetterway.

While construction we can face many problems like design, planning etc, by using primavera we cancoordinateonthepersonspresentonthesite.

Whenwecompareconventionalandprefabricated building, we can understand the difference between them. In conventional building it is a traditional method which is coming from ancient time, whereas prefabricated construction method is a new method of construction which needs less timetoconstruct.

The lifespan of both buildings is comparatively same,themaindifferenceisthattimeandcost.

From estimation we can know that prefabricated building needs less time and more cost, whereas the conventional building needs more time and less cost as compared to the prefabricated building. 

In prefabricated building there are many new techniques used for construction of prefabricated buildings, machines are used more but in conventional building machines and labours are usedinequal. 

From this project we can conclude that both construction methods are good but we have more timewecangoforconventionalconstruction,ifwe have lesser time then we can go for prefabricated construction method the cost will be more in prefabricated construction method as the steel rateismore.
