    FOUNDATION PREPARATION

    3.1 INSPECT AND VERIFY INTERFACE AND TERMINAL POINTS

    Verify temporary construction and permanent terminal points as defined in the contract.

    (Refer to MLI 0306, MLI 0323, and the site plot plan.)

    3.2 VERIFY FOUNDATION EMBEDMENTS AND SUPPORT AREAS, ETC., FOR

    TURBINE, GENERATOR, PIPE SUPPORT PIERS (BOP)

    Check foundations for correct location, size, elevation and potential interference of

    grout pockets, anchor bolts, restraining blocks, jacking posts, and conduit stub-ups for

    the Combustion Gas Turbine, Generator, Packaged Electrical Electronic Control Center(PEECC), Accessory Module, Liquid Fuel/Atomizing Air Skid, Generator Auxiliary/Static

    Start Compartment (GAC), Cooling Water Module, Fire Protection Skid, Water Wash

    Skid, Liquid Fuel Forwarding Skid, and Water Injection Skid.

    Check existing pipe support piers for correct locations and the potential interference

    with other equipment.

    3.3 SET AND GROUT FOUNDATION/SUB-SOLE PLATES (BOP)

    Set, level per specifications, and grout sub-sole plates for the gas turbine base and

    generator base. Prior to setting of sub-sole plates, they must be cleaned (preservativecoating must be removed), and deburred. Shim plates and packs must also be cleaned

    and deburred.

    Recheck plate elevation and level after grout is cured. Shim packs are to be set prior to

    setting equipment. (Refer to MLI 0323 notes).

    3.4 INLET AND EXHAUST SYSTEM FOUNDATION (BOP)

    Check existing foundations for correct anchor bolt locations and potential interference

    with the gas turbine inlet system (MLI A040 and A041), and exhaust system (MLI

    A042). (Also refer to MLI 0323 Notes.)

    3.5 AUXILIARY MODULES, SKIDS AND ENCLOSURE FOUNDATIONS (BOP)

    Check foundations for correct anchor bolt locations, if provided, and potential

    interference with the following off-base skids:

    RECEIVING AND STORAGE

    3.6 RECEIVE TURBINE, GENERATOR, TURNING GEAR AND ALL OTHER GE

    SUPPLIED EQUIPMENT

    3.6.1 Receipt of Equipment and Materials

    Inspect all incoming material for loss or damage. Inspection includes the

    protective covering and packing for obvious damage, blocking of

    components on delivery carrier for shifting during shipment.

    Checking factory installed accelerometers (hump meters) where provided

    (normally the turning gear, turbine base front and aft ends, and generator

    base front and aft ends).

    Other equipment that will be received includes; Accessory Module,

    Atomizing Air/Liquid Fuel Module, PEECC Compartment, Batteries, BAC,

    Water Injection Skid, Cooling Water Module, Fire Protection Skid, Liquid

    Fuel Forwarding Skid, and Water Wash Skid.

    Loss or damage should be reported in accordance with receiving policies,

    procedures and regulations.

    3.6.2 Storage Of Equipment And Materials

    Equipment and/or materials are to be stored and/or preserved in

    accordance with General Electric GEK-28156B Gas Turbine and

    Accessory Equipment Preservation Instruction. Some equipment (e.g., gas

    turbine-generator) may require temporary power for heating or drying either

    prior to or once it is set on the foundation, depending on weather conditionsand the duration. Material should be arranged to accommodate efficient

    installation.

    3.7 RIGGING AND SETTING EQUIPMENT

    Installer is responsible for all off-loading, on-site transportation, rigging, lifting and

    setting of items outlined on Exhibit A.

    GE Energy Services

    3.7.1 Unloading And Hauling

    Receive and off-load the equipment.

    Remove all shipping braces, saddles, bolsters, shipping covers, packing

    and supports in accordance with instructions and drawings. Do not remove

    rotor locking devices until equipment is set on the foundation.

    3.7.2 Equipment Erection

    Installer will be responsible for verification of the actual lifted weight and

    dimensions of equipment and materials per MLI 0408. Estimated weights

    and dimensions are shown in Exhibit A.

    SET, ALIGN, KEY, AND COUPLE CENTERLINE EQUIPMENT(Refer to MLI 0411)

    3.8 FOUNDATION BOLTING ARRANGEMENT (MLI 1603)

    Arrange for the foundation bolting arrangement to arrive at the site at least four (4)

    weeks prior to the delivery of the major centerline equipment. This affords the Installer

    sufficient time to prepare the sub-sole plates, shims and centerline guides (See Fig. 3).

    Note: The preferred method of setting gas turbine and generator is to rig, pick-up

    and set with a crane or gantry crane. Another method is to set the

    equipment on skidding device and roll from the truck onto foundation.

    3.9 GAS TURBINE

    Set turbine down on hard wood blocking approximately 24 to 36 high over anchor

    bolts. Jack turbine down over anchor bolts on sub-sole plates and shim packs. Adjust

    shim packs to correct centerline elevation. Installer will provide all materials such as

    anchor bolts, nuts, one inch (1) washers etc., and grout required for setting and

    leveling. (See Fig. 4).

    3.10 INSTALL LOAD COUPLING TO TURBINE (INLET END) (MLI 1319)

    Installer is responsible for assembly and installation of the turbine load coupling. All

    bolting is to be measured, assembled and torqued per specifications. The field has

    found it easier to assemble the coupling to the turbine before setting the generator (See

    Fig. 5).

    3.11 GENERATOR (A013)

    Unbolt and remove generator rotor locking device. Jack the field approximately one inch

    (1) aft (toward collector end). (Refer to MLI 0411 Field Alignment Instructions.)

    Set the generator down over anchor bolts on sub-sole plates and shim packs. Adjust

    shim packs to correct centerline elevation. Installer will provide all materials such as

    anchor bolts, nuts, washers, etc., and grout required for setting and leveling (See Fig.

    6). (Refer to Contract.)

    3.12 COLLECTOR ASSEMBLY AND TURNING GEAR

    Installer will be responsible for the installation of all parts of the collector arrangement

    and the turning gear. All bolting is to be assembled and torqued per GE specifications.

    3.13 INSTALL TURBINE EXHAUST DIFFUSER (MLI 0706)

    Installer will be responsible for assembly and installation of all parts of the turbine

    exhaust diffuser. All bolting is to be assembled and torqued per GE specifications.

    Installer will be responsible for installation of diffuser insulation over outside skin. (See

    Figs. 7 and 8).

    3.14 ALIGNMENT OF GENERATORTOTURBINE, COLLECTOR ASSEMBLY AND

    TURNING GEARTOGENERATOR (MLI 0411)

    Alignment will be performed as described in GE document Basic Field Alignment

    Instructions (MLI 0411). Alignment readings will be witnessed by the GE Technical

    Advisor.

    3.14.1 The turbine and generator bases must be in a free standing condition, i.e.,

    no off-base air, water, fuel gas, fuel oil or lube oil piping, conduit or bus duct

    is to be made up to the turbine and generator bases. The collector assembly

    and turning gear shall also be free standing with no lube oil piping wiring or

    conduit connected.

    3.14.2 Final alignment readings will be taken in accordance with GE instructions.

    Note: The Exhaust Diffuser (MLI 0706) must be assembled to the

    turbine before final readings are taken.

    3.14.3 Installer will final align generator to turbine, turning gear to generator, install

    foundation centerline keying devices and make up couplings per GE

    drawings. It is recommended that alignment readings be witnessed and

    signed off by the Owner, Installer and General Electric. (See Fig. 9).
