6.0 METHODOLOGY :GENERAL : Foundation shall be completed and checked for correctness and levelness as per drawings and specifications. Prior to installation, foundation shall be clean with correct anchor bolt holes location, centerlines marked, elevations and levels established for correctness. Shimming and wedging shall be carried out as per drawings and specification. As required, perform on site installation of the various equipments as per approved construction drawings and specification and instruction by a manufacturer/vendor representative.ROTATING EQUIPMENT INSTALLATION:1. Prior to installation, inspection for equipment acceptance to be carried out. Equipment installation includes loading, hauling, unloading, inspection, lifting, shimming, aligning, placing and securing in its final position.2. Remove all temporary supports, bracing or other foreign objects that were installed in the equipment or machinery to prevent damage during shipment, storage and erection, and repair any damage sustained. This may need vendor assistance.3. Before positioning the equipment, it shall be checked against the drawings to verify the pipe installation of flanges, nozzles, junction boxes, coupling and other items that require external connection.4. HDOL to prepare lifting and rigging plan for all heavy lifts taking into consideration location and other activities such as equipment insulation, structural platform and ladder, instrumentation, piping erection and other work which can possibly be accomplished prior to final erection of equipment, saving scaffolding and basket work.5. The foundation and anchor bolts preparation shall be completed and checked by PMC/OWNER inspector prior to installation of equipment.

6. Prepare foundation surface, install equipment, and level the equipment as per approved drawings and specification.7. Inspect and check the work during the construction stage, and perform such non-operational tests as are necessary to assure the integrity of the installation in accordance with the issued for construction drawings, specification and vendor instruction.8. Conduct all operational tightness tests.9. Qualified craftsman with experience in installing rotating equipment will be assigned at site during the erection, installation, commissioning and start-up period with vendor assistance as required for all special equipment. INSTALLATION OF PUMP AND OTHER ROTARY EQUIPMENT:

Rotary machines and equipment, such as pump, blower, agitator, etc will be installed in the ETP Project. The installation methods are as follows: 1. For pump installation, alignment of axle centers between driving machine (motor or turbine) and pump is of essential importance. When connecting driving machine to pump, axial line of pump shall be taken as reference for alignment; when there is intermediate equipment installed between driving machine and pump, axial line of intermediate equipment shall be taken as reference for alignment. Generally, three (3) gauges will be adopted for alignment at the same time.2. In general, liner and shims will be used for installation. And according to the type of base plate, flat liner and shims, wedge or small jacks will be used to facilitate the adjustment.3. Non-shrinkage cement mortar will be used for grouting work. Foundation of pump and machine will be grouted in two lines. After initial alignment, primary grouting will done for anchor bolt holes. When the mortar reaches certain strength, precise alignment will be performed, then secondary grouting work may be carried out.4. The parallelism and concentricity between flanges of piping to be connected with pump and inlet/outlet flanges of pump shall meet requirements stated in relevant specification. And during connection, no undue stress will be imposed on pump body. After final alignment, dial indicator will be applied when connecting piping flange to pump flange.

5. Rotate pumps by hand to ascertain that they turn freely. Align pump with driver after coupling installation; ensure that the axial and radial deviations, and axial clearance are within the approved tolerance.

6. Disconnect the coupling, check motor for rotation, run-in uncoupled and check bearing. After motor no load test, re-couple pump to motor.

7. Installed proper lubricants(fuel, coolant) prior to commissioning after review with PMC

8. Installed strainers in the suction piping to prevent foreign objects from entering the pump during commissioning and initial operating period.

9. Test run of pump will be performed after successful test run of each auxiliary equipment.

10. Check the general compatibility of the pumps with respect to any cavitations problem, discharge head, excessive vibration, excessive noise etc. which may hint at abnormal operation of pump.11. Test run of pump shall be done with working medium.12. For installation of dryer, suitable gradient shall be guaranteed in compliance with requirements specified in vendors technical document. First base plate shall be installed and aligned to certain gradient, Then cylindrical shell will be installed and bearings and other screw conveyor will be inspected and adjusted, and then expansion joint flexible coupling and outlet hopper will be installed. Finally motor will be installed. During installation, axial center of motor shall be precisely aligned.13. For installation of agitator, technical specification and codes by PMC shall be strictly followed, especially the agitator of reactor, perpendicularity requirement of its center axle is very strict, so after positioning of reactor, not only the perpendicularity of housing shall be carefully measured, but also leval of top flange(connected with agitator flange) shall be precisely adjusted, to assure the perpendicularity of center axle of agitator.14. Activities relevant to tolerances for agitator horizontal/vertical alignment shall be performed according to the technical specification provided by PMC. Any misalignment of relevant vessels must by adjusted accordingly.7.0 SAFETY

During fabrication and erection adequate safety measures shall be taken as per the safety norms/Standard.

All workers shall must wear appropriate PPEs like safety helmets, safety shoes, safety belts, goggles, gloves etc.

Suitable scaffoldings shall be provided to workmen for all works that cannot be safely done from the ground.

Ensure electrical systems and equipments including tools & tackles used during construction phase properly selected, installed, used and maintained as per the Standard.

Fire extinguishers and insulating mats shall be provided at power distribution area.

8.0 QUALITY ASSURANCE & QUALITY CONTROL

Quality Assurance & Quality control of ERECTION work shall be as per Quality Plan .All quality records as appended to this procedure shall be maintained for all activities.

9.0 DOCUMENTATION AND RECORDS All records pertaining to execution of the job as per ITP No. HDOL/ETP/6249/JP/MECH-TANK-001/REV-0,

to be maintained by the contractor as the work progress & till its completion and then handed over
