Implementation of construction project needs a proper planning and scheduling is of vital importance for the project to be executed and run smoothly. A best schedule has to be prepared in such a way that meets the primary objectives of the total project. Those essential destinations are to make a quality venture, finished on time, inside spending plan, and in a sheltered workplace. Consequently in this investigation a progressing development venture is taken and the execution of the undertaking is contrasted and the calendar with the assistance of Primavera. With the help of management tool like primavera, one can manage the scheduling, resource allocation and also time management in a proper and easy way.


I. INTRODUCTION
The development business assumes noteworthy part in the economy of creating nations. For instance, in numerous creating nations, significant development exercises represent around 80% of the aggregate capital resources, 10 % of their GDP, and over half of the riches put resources into settled resources. Moreover, the industry gives high business opportunity, most likely next after agribusiness. In spite of the development business' huge commitment to the economy of creating nations and the basic part it plays in those nations advancement, the execution of the business still remains by and large low. As noted, numerous ventures in creating nations experience extensive time and cost invades neglects to understand their expected advantage or even completely ended and surrendered previously or after their finish. Also, the improvement of the development business in creating nations by and large falls a long ways behind from different ventures in those nations and their partners in created countries. The development business in creating nations neglected to meet desires for governments, customers and society overall.
The procedure of task administration is an integrative one-a move (or inability to make a move) in one territory will for the most part influence different zones. For instance, an extension change will quite often influence cost and timetable appraisals, yet it might likewise affect different factors as assorted as camaraderie and item quality. This cooperation regularly require exchange offs among venture destinationsexecution in one territory might be improved just by yielding execution in another. Fruitful undertaking administration requires currently dealing with these connections. In this investigation, I am gathering information of an undertaking which is executing under government organization.

A. Risk analysis
Hazard Analysis and Management is a key undertaking administration practice to guarantee that minimal number of astonishments happen while your venture is in progress. While we can never foresee the future with assurance, we can apply a basic and streamlined hazard administration procedure to anticipate the vulnerabilities in the ventures and limit the event or effect of these vulnerabilities. This enhances the possibility of effective venture fruition and lessens the outcomes of those dangers. Task colleagues at different levels distinguish and handle chances in various flavors. Nonetheless, this will be incapable without an organized hazard administration system, as this prompts:  Incomplete affect assessment  Knowledge of the general effect on the venture goals, similar to scope, time, cost, and quality  Identification of auxiliary or new dangers emerging from the officially recognized dangers  Lack of straightforwardness and a correspondence hole inside and outside the group Along these lines, it is essential for any undertaking association to set up a viable hazard administration structure. Organizing such a training as a task group culture guarantees.  Conscious and centered hazard ID and administration.  Project advance as wanted, with minimal measure of deviations or shock, and in accordance with venture and authoritative targets.  Early and compelling correspondence of venture issues to association and undertaking partners.  An compelling group building device, as group purchase in and acknowledgment is guaranteed.

B. Primavera P6
Primavera is an undertaking venture portfolio administration programming. It incorporates venture administration, item administration, cooperation and control capacities, and coordinates with other endeavor programming, for example, Oracle and SAP's ERP frameworks. Primavera was propelled in 1983 by Primavera Systems Inc. It can perceive principles for elite undertaking administration programming, is intended to deal with extensive scale, very advanced and multifaceted activities. P6 Professional can be utilized to sort out tasks up to 100,000 exercises, and it gives boundless assets and a boundless number of target designs. Huge information requires complex yet very adaptable association apparatuses to give you a large number of approaches to arrange, channel and sort exercises, ventures, and assets. Data of project is taken from an executing G+1 site located at Lalghati, Bhopal M.P. The construction work of the project is in progressing condition. This project is constructing at an area of 5300 square feet. The construction amount is 96 lakh, and duration is 24 months including rainy season.

B. Methodology
Following steps are to be execute in a sequence are as follows: Step-1 is to collect data of the site in which details of each activity and its quantity is required.
Step-2 is to prepare a scheduling using management tool primavera p6 to determine its actual running condition.
Step-3 to determine the manpower required for each activity by computing resources using I.S. 7272 using quantity analysis.  Step-4 to reschedule the project using primavera with providing lagging and links between various activities.  Step-5 to compare both the scheduling and resource allocation to determine cost variations.
Step-6 to prepare gantt chart and study both the planning

A. Cost Variation in Rupees Overall Cost
The principal contribute of a contractor's costs and expenses result from the use of labors, materials, gear, and subcontractors. Extra broad overhead cost segments incorporate duties, premiums on securities and protection, and enthusiasm on advances. The aggregate of an undertaking's immediate expenses and its distributed aberrant expenses is named the Overall cost.                        In this work, planning and scheduling of an ongoing project is prepared using management tool primavera P6 and it is compared with the scheduling adopted by the government bodies in this project in terms of duration, resources and cost. The requirement of manpower for every activity of the project selected for this study i.e. Construction of government higher secondary school located at lalghati Bhopal M.P.is obtained using I.S. 7272 -I in which labour constants are selected according to activity and quantity of work.
The logical sequence of activities with constraints were determined and assigned on the basis of work involved and past experience. Based on data obtained, Gantt chart and network diagram is prepared and relations are assigned to activities. The duration of project were defined at different level like sub project level, work package level, activity level, operations level.
In construction project, the time duration is generally related to the quantum of resource employed. The software also help us to calculate the duration required to complete the project according to the planned schedule and actual performance of activity at any time and it gives the idea about project is on schedule, ahead of schedule, behind the schedule. The manpower & resources schedule is prepared which gives a clear picture of labour& materials requirement in exact number during the execution period of the project. Then in this study, manpower & resource planning, scheduling and tracking is done using Primavera P6. After preparing the schedule in Primavera Software, the total project duration is estimated and compared with ongoing site work. Now for tracking the percent completion of project in the software, the progress of individual activity is given according to their progress of work and compared with site work. After tracking, at status date of 11-09-2017, the project % complete should be 100%.
In this work we can conclude that with the help of management tool (primavera P-6) we are completing the project of 24 months before given time in 20 months, saving indirect costs of 04 month such as employee salary, machinery rent, fooding, lodging, maintenance etc.
In terms of cost it is clearly observed in above chapter that overall cost is decreasing by 6.67%.
In this project the following benefits were obtained by scheduling it for 20 months instead of 24 months are as follows: 1. Here the most important benefit is that we completed the project within given time limit which will minimize the risk of natural calamities. 2. We minimize our indirect cost which includes salary of employees, machine repairing costs and other site expenses
