from the signing of theAgreement between the Client and Contractor. However, the effective participation of the contractor will start from the date of receipt of letter of intent (LOI) and the project kick offmeeting, where project scope and basis will be formally agreed.Contractors plaque ChartsThe Contractor will appoint a Project Manager to take total charges of scope of work for which they are responsible. The structure is shown in the organization charts.1.2 general Project ExecutionThe Project Manager and his team are the primary interface point between the Contractor and Client. It is via this interface that all the day-to-day rest passes and project report are issued. The Project Manager with his team oversees the contractors scope of work. The projects coordinator is responsible for the coordination between Client, technology, Procurement, Fabrication and the Site Operation.As soon as LOI is issued internal Kick-off meeting will be held to firm up the project procedures. In order the successfully achieve its objective the Project Manager issues the Project Dossier dilate the interface between Contractor and the Client. It sets out the detailed working method to be employed by them though all phases of the job.With the co-ordination procedure the project chronicle and methods of measuring progress and controlling the work are also issued.Inventory ProcedureQuality ControlShipping Procedure and ForecastField Project Control ProcedureField Safety ProcedureChange Order Procedure.1.3 Design and EngineeringThe Client has given the basic design. The detailed design for Contractor (in house) will carry out the project2. Procurement hoagy- contracti ngContractor will prepare material requisition for all plant, equipment and materials and the Procurement in-charge shall manage the procurement and sub contracting. He will establish the procurement plan, identifying the finite list of requisition to be issued by the engineering groups, to start procurement cycle. Contractor will issue enquiries and obtain offers. Purchase orders will be placed by the contractor on vendors approved by Client, offering bestTechno-commercial terms.A list of critical long lead items will be established including long lead item and those critical to programs. Special monitoring of these items will be carried out to ensure timely delivery.Procurement service offered by the contractor will include bid evaluation, arranging vendor coordination meetings, selection, placement of purchase orders, amendment of purchase order and modified if necessary, to reflect any specific requirements of the specific order.3. ConstructionContractors Construction group wil l supervise the construction to be carried out in a phased manner. It will be responsible for field inspection, material and inventory control and logistics for timely executing of the project.Contractors Project Manager will ensure quality and inscription so that the construction is done as per the detailed design/engineering document prepared by Client and within agreed time frame.4. Pre-commissioning and commissioningThe Commissioning Group headed by the Commissioning Engineer of the contractor will direct and supervise to provide the necessary assistance to the pre-commissioning and commissioning activities of Client. Project in co-ordination with the Commissioning in-charge of Main contractor/consultant. The major activities of this group will include Check plant units for mechanical completion at size.Prepare pre-commissioning programme to redact priorities during final stage of counteraction work.Planning and scheduling of plant start up activities.Co-ordinate and supervise the start up of the plant.Main contractor/consultant shall conduct process guarantee test turns.5. Project scheduled, control and reportingContractors system of project planning scheduling and monitoring is designed to provide schoolwide planning services to the project management team. This system is instrumental in devising realistic schedules establishing checkpoints, keeping boilers suit watch on the progress, deviation from schedules, pinpointing the line of work and recommending areas of corrective actions. The details are given below6. Planning Scheduling6.1 Proposed Schedule and overall project scheduleThe proposed project schedule is submitted along with this proposal. This indicates the project starts date, end date and major milestones of the project the proposed schedule is prepared in the form of bar chart schedule.On award of the control, the proposed schedule is converted into an overall project schedule in the form of squared PERT network on time graduated tabl e. This network includes overall engineering, procurement and construction duration as well as critical and near critical items for each system. This overall schedule forms the basis for execution of the contract and is used for corporate project review.6.2 senior pilot NetworkFor project control, master network is prepared for the project, master network is updated internally every month, this is revised if (i) The overall project schedule is revised, (ii) There is a major change in the scope of work, (iii) unforeseen events beyond contractors control. The master network forms the basis for detailed scheduling and project control.6.3 Function SchedulesAt the level of the executing departments, functional schedules are prepared for all functions, viz. process, residual engineering, ordering and delivery. Standard Networks for various functions are used for sequencing various activities in the schedules. These schedules are also used for scheduling projects physical progress and its measurement.6.4 Key Construction NetworkThis network is delivered from master network. This is made, work area wise, on time scale The number of networks to be prepared depends upon the workload into which the plant is divided. These networks are prepared at a time when engineering and procurement activities have sufficiently good and construction activities are about to begin or major milestones such as deliveries of equipments at site, start and completion of civil works, mechanical erection etc., are about to be achieved.6.5 ReportsBasically, three types of reports are produced. First type of report contains activities to be performed in next two months and is known as Activity List. trice type of reports gives the status of drawings, materials, etc. and is named Status Report, which highlights the deviations and exceptions and immediate actions. The Third Type of Reports is the one, which summarize progress report at various time intervals.6.6 Monthly come out ReportMonthly progress report is basically meant for Client. This report gives a comprehensive coverage of engineering, procurement and construction activities carried out during the month under review. The periodical report apprises the Client of the progress of the project and holds up if an in achieving the progress. The report contains the following informationOverall progress statisticsStatus of milestonesList of problems/hold ups structural progress curvesQuantitative status report for equipmentDetailed status of constructionD.
