Kemenperin ‘Sentil’ Industri Pembuang Karbon Terbesar – Pemerintah melalui Kementerian Perindustrian mendorong pelaku industri untuk menurunkan emisi gas rumah kaca pada tahun 2020 sebesar 26 persen.

“Dari 700 perusahaan penyumbang CO2 mencapai 114,41 mega ton. Dan terdapat 8 sub bidang industri yang lahap energi, yaitu industri semen, pupuk, petrokimia, besi dan baja, pulp dan kertas, tekstil, keramik,minyak goreng dan gula,” kata Kepala Badan Penelitian dan Pengembangan Industri Haris Munandar, di Kemenperin, Senin (15/2/2016)

Lanjutnya, Pemerintah mendorong pelaku industri untuk pelaksanaan alih teknologi untuk teknologi efesien. Salah satu teknologi yang digunakan adalah teknologi regenerative burner combustion system (RBCS)

List of step for ESC construction project:

  1. Quotation

  2. Proposal Drawing

  3. Approval Drawing
    Approval drawings are the structural drawings of erection drawings which are sent to the customer or consultant to verify the design, dimensions and functional requirements. Usually 3- sets of approval dugs are sent. One of which is sent back to us with properly stamped and signed with/ without comments.

    We send these approval dugs with due care so that all drugs are self- explanatory, easy to read by the customer or consultant.

    Approval drawings normally contains:
    • Anchor Bolts lay-out and plan
    • Frame cross-section
    • Roof framing plan
    • Side elevation
    • Longitudinal elevation
    • Roof-sheeting plan
    • Connection detail
    • Accessories and detail
    • Appropriate note, lay-out & assumption

  4. Design Calculation
    Design calculation is the document for structural analysis and design procedures for the main structural components of the building. Design calculation report is usually submitted when it is required by the customer. No approval is required by the customer for the design calculation. Gunung Garuda takes full responsibility of structural safety of the building.

    For design without specific requirements, we will design the building in accordance to the following codes:

    1. AISC (American Institute of Steel Construction) Manual, 1989 edition
    2. MBMA (Metal Buildings Manufactures Association) Manual, 1996 edition
    3. AWS (American Welding Society) Manual, 1996 edition

  5. Shop Drawing (Cutting Drawing, Assembly Drawing)
    Shop drawing is the Gunung Garuda internal fabrication drawings based on components which are all prepared in our own workshop. We use high precision 3- D modeling software to prepare the shop-drawing with high degree of accuracy in a minimum amount of time.
    1. Cutting drawing (or, component drug) which are fit to cut, drill, punch, notch etc. by our CNC machine)
    2. Assembly drawing, which is used to fabricate all components in our workshop

  6. Bill of Material
    Bill of material (BOM) is the history report of all the structural component to be used for the structure. Once the shop drawing is in drum, BOM comes and automatically from the 3- D modelling software which gives better efficiency and minimize human error.

  7. Packing List
    Packing list is the list of materials that have been packed and ready to be delivered to costumers based on marking which is significant to the delivery list.

    List of materials, as follows:

    1. The following material standard/class or group needs structure
    2. Quantity/unit of amount
    3. Marking
    4. Weight
    5. Data of container's number
    6. Number of seal

  8. Container Unloading
    This manual describes pictorially with appropriate explanation about the unloading procedure of the material at the erection site. Container unloading manual helps the erector to remove all the material with prospect attention, quicker and faster way without any damage.

  9. Erection Drawing
    This is the standard manual which describes vividly what measures are to be taken and what erection equipments are to be procured for the easy, faster and safe erection of the building.

    Erection drawings are the drawings which are sent to the customer/erector to build the structure at site. It describes how to erect the building. To have a proper visualization we issue a 3 dimension perspective view with the all cross-sectional and detail drawings.

    Our erection drawings are well explained and properly presented. No pre-assumption and specific knowledge for steel building erection are required to understand these drawings.
