BUILDING COST TABLE IN INDONESIA (MAPPI’S BTB TABLE) By : BTB Team – MAPPI , 2014 Summary: Started in 2010. The Table of Building Cost are developed in 2 stages. - First stage: Residential, Industrial building and shop house building. - Second stage: High Rise Building Updating Period: 4 months Adjustment: - Location - Quality / Building Specification 2 STAGES OF BTB/BCT : FIRST STAGE: TABLE SCOPE: RESIDENTIAL , INDUSTRIAL BUILDING, SHOPHOUSE ADJUSTMENT: LOCATION ADJUSTMENT AND QUALITY/MATERIAL ADJUSTMENT LAUNCHING: OCTOBER 2013 SECOND STAGE INTERACTIVE SCOPE : HIGH RISE BUILDING ADJUSTMENT: LOCATION INDEX LAUNCHING: DICEMBER 2014 BTB DEVELOPMENT STAGES 2 STAGE 1 STAGE 2 TAHAPAN PENGEMBANGAN SISTEM BTB BACKGROUND COST APPROACH A set of procedures through which a value indication is derived for the fee simple interest in a property by estimating the current cost to construct a reproduction of (or replacement for) the existing structure, including an entrepreneurial incentive; deducting depreciation from the total cost; and adding the estimated land value. Adjustments may then be made to the indicated fee simple value of the subject property to reflect the value of the property interest being appraised. The Appraisal of Real Estate, 2008 The base unit cost of the model most representative of the subject building is applied to the subject building and appropriate tables of additions and deductions are used to adjust the base cost of the subject building to account for any significant variations between it and the model The Principle of BTB Table - - - Become a Reference for valuer in Indonesia in calculating Cost New Reproduction or Replacement Cost New a building. - National Technical Standards - Adjusted to market conditions, quality of building and object location Benefits Of BTB 1. Standards Cost Basis Calculations for New reproduction Cost of building 2. Easy to use and efficient 3. Integrated Indonesia Technical National Standard and Indonesia Valuation Standard 4. Market base on RCN Calculation and updated every 4 month on the construction cost Technical Reference Regulation Description UU No.18 Tahun 1999 Construction Services Keppres No.80Tahun 2003 Guidelines for Procurement of Goods / Services SE Sekjen Dep.PU No. 05/SE/SJ/2005 Increased Application of Procurement of Goods / Services within the Department of Electronic Public Works FY 2005 Keputusan Menteri Keuangan NO.427/KMK.02/2004 Common Unit for Fiscal Year 2005 UU No.28 Tahun 2002 Building Kep Dirjen Cipta Karya No.295/ KPTS/CK/1997 Building Technical Guidelines UU No.4 Tahun 1992 Housing and Settlement Uu No.28 Tahun 2002 Building PP No. 4 Tahun 1988 Rent House Kepmeneg Perumahan Rakyat NO.06/kpts/1994 General Guidelines for Housing Development Rests In Group (P2BPK) Kepmeneg Perumahan Rakyat No.04/KPTS/1999 National Strategy for Housing Policy Settlements (KSNPP) BUILDING ELEMENT (AS PER DEP.

Unit price of timber for construction buildings and residential buildings. (ISO 3434:2008 2. Unit price of sand for construction of buildings and housing. (SNI 3835:2008) 3. Unit price for the foundation work and residential building construction (SNI 3835 : 2008) 4. Unit price for the wall work and residential building construction. (ISO 2837:2008 ) 5. Unit price ceiling for the construction of buildings and residential buildings. (SNI 2839 : 2008) 6. Unit price of steel and aluminum for the construction of buildings and residential buildings. (SNI 7393 : 2008) 7. Unit prices for concrete construction work and residential buildings. ( ISO 7394:2008) 8. Unit price floor and wall coverings for building construction and housing (SNI 7395 : 2008 ) 9. Unit price work for Roof Covering and residential building construction (SNI 6897 : 2008) Analysis of Unit Prices Analysis of Material Analysis of Labor Costs, Analysis of Equipment Analysis of Unit Price Material Σ Materials = Volume of work x material coefficient analysis Analisa Harga Satuan Upah / Analysis of Unit Price Wage Σ Labor = Volume of Work x coefficient analysis of labor Analysis of Unit Price Equipment Bottom of the unit price consists of: - Initial Cost or Capital Cost - direct Operational and Maintenance Cost UNIT PRICE: A. Direct Cost 1. Cost of materials 2. Labor Cost 3. Equipment cost B. Indirect Cost 1. Overhead Project Total overhead can range from12 to 30%. 2. Profit about 8 to 15% 3. Professionals Fee 4. Building Permit Figure 1. Diagram of Unit Price (Source : SNI 2008) EQUATION OF UNIT COST OF WORK: The Scheme below show how the MAPPI’s BTB table was formed: Figure 2. The Scheme of MAPPI’s BTB table UNIT IN PLACE SCHEME Figure 3. The Unit in Place Scheme in the BTB Table Application of BTB 1. Establish the structure quality class 2. Multiply the structure floor area 3. Multiply the total by the correct location listed on the location indexes 4. Add when appropriate the cost of different material used in the object and multiply to the quality index of material Two adjustment in calculating the RCN using BTB Table, there are: 1. Specification adjustment of quality adjustment 2. Location adjustment Table 3. Quality Material Index 2. Location Adjustments Sample of Location Index can be seen in the table below: Table 4. Location Index of BTB Table 5. Sample of BTB/BCT in Jawa Barat Province
