1.0 INTRODUCTION

AGRU / AGE (LIR-18) is to be instaled on the concrete Pedestals in Banyu Urip Site at Cepu, Indonesia. LIR-18 is building without split. Size of LIR-18 is 10.3 m x 4.4 m x 4.1 m.

1.1 SUMMARYThis report contains the weight and Centre of Gravity (COG) estimates for the substation Modules. The overall module weight contains primary and secondary structural steel, architectural, electrical & Instrument bulk weight, and equipment weights.

Primary structural steel shall include the following: Primary Floor Framing Primary Roof Framing Column Interconnection Column Floor Deck Plate Lifting pad eye

Architectural weight shall include the following: Equipment Support Beams Wall Plate and supports Roof Deck Plate Roof Insulation Secondary Floor Framing Secondary Roof Framing Secondary Wall Framing Roof Insulation Wall Insulation Underfloor Insulation Internal Wall Panel Ceiling Doors Belly Pan & support Inside Cable Trays HVAC & Ducting Gland box

Equipment weight shall include the following: Equipment mounting on the floor Equipment mounting on the wall

Lifting aids and slings weights are tagged as installation aids. Some disciplines are computed from drawings that give preliminary process information.

To provide a consistent gauge for the contingency calculation adjustments, the ‘Weight Growth Contingency Matrix’ is used. The Matrix distinguishes between bulk materials and the tagged equipment items and is based on industry-accepted practice. A contingency code is assigned and continually revised based on the completion status of each item in the estimate. Refer to section 3.3 for the contingency codes and descriptions.

The base weights current weights and centre of gravity for lifting/loadout are summarized in their respective tables, which are found in section 5.

1.2 OBJECTIVESThe objective of weight control report is to provide an approximate estimation of Substation Module weight & COG. It is also important to continously monitor the generated weight components of various items to be constructed / installed into the substation module. The structural steel weights and COG will be combined with various engineering weight data in order to obtain the combined module weight and COG. During the preparation of this report, the supply of all weight for all main items are provided by the various engineering disciplines. If the weight is not available, the estimated weight based on a project with the same nature is assumed by each disciplne.

2.0 SCOPE OF REPORT

2.1 ANALYSISIn Preparing the weight control report, sum of the items have not been fabricated and installed. Hence, the weight estimated only assumed by each dicipline based on preliminary or approved structural and electrical equipment layout drawing.The above figure shows the reference datum used for COG definition. In the vertical direction, the origin is to be the Module floor level (T.O S Floor), positive going up.The weight and COG of the structural members are compiled in a Microsoft Excell Spreadsheet, which is programmed to compute the overall weight and COG of the Substation Building as a whole.

2.2 CONCLUSIONSThe weight control engineering has been compiled based on preliminary drawings. The Structural weight has been taken from “IDBC-TS-VDSTR-T100639-PG0002_Rev1,” LIR 18- Structural Support, Framing Plan & Elevations Views”. The Architectural weight has been taken from “IDBC-TS-VDDET-T100639-C00018_Rev 0 ,” LIR 18- General Arrangements & Architectural” and from “IDBC-TS-VDELE-T100639-PG0102_Rev 0 ,” LIR 18- Bottom Opening & Gland Boxes Detail” .The electrical equipment weight has been taken from “IDBC-TS-VDLAY-T100639-PG0002_Rev 0,” LIR 18- Architectural Plan Layout / El. Equip. Layout”.

3.0 WEIGHT CONTROL PROCEDURE / METHODOLOGY

3.1 DEFINITIONS

The following abbreviations are used in the document, and are defined in the following sub-sections:

COG : Centre of Gravity

T.O S : Top of Steel

3.1.1 Base Weight This is the theoretical weight, which is obtained from:

calculation using latest available design drawings/sketches;

best estimates

vendor data

weighing

The base weight includes no allowances or contingencies.

3.1.2 Control Weight The Control Weight is the weight assigned by the Weight Control Engineer to each discipline, which their Factored Weight should not exceed.

3.1.3 Lift WeightLift Weight is the Gross Weight of an item or the total Gross Weight of items in a fabricated unit or module that is to be lifted. The Lift Weight does not include an allowance for impact the weight of rigging is not included, while items removed prior to lift, e.g. access ladders/platforms, are excluded

3.1.4 Discipline Codes The following discipline codes are used for reporting purposes :

Table 3.1.8. Discipline Code

DISCIPLINE DISCIPLINE CODESTRUCTURAL STRUARCHITECTURAL ARCHEQUIPMENT EQUIP

3.2 METHOD

3.2.1Data Requirement from DisciplinesIn general, the weight and COG of all items with a weight equal to or greater than one tones weight shall be specifically and individually reported. All other items will be included in the weight of the appropriate category of bulks.

Structural

The dry weight and centre of gravity for all items and materials are based on preliminary information.

Architectural

All items are based on preliminary information

Equipment

The weight and centre of gravity for all items and materials are based on preliminary information.

3.2.2 Weight and Centre of Gravity ControlWeight and centre of gravity control is to estimate the whole weight of each substation for the later designs.

5.0 OVERALL SUMMARY REPORT

The weight summary for the Substation building is tabulated in the table detailed in section 5.1.

5.2 COG ENVELOPECOG of the Substation buildings shall be consistently monitored such that the shift will not cause the lifting analysis design and its lifting pad eyes to be in-validated. A final lift analysis check will be carried upon final weighting and to ensure the structural adequacy of the module is not impaired. The COG of the Substation buildings for Lifting/Loadout condition is tabulated in the Table below. The COG of the Substation buildings is measured based on the Coordinate Systems stated in section 4.0.
