BIM for steel & precast concrete erection


BIM based 3D model provides exact visual representation of the steel sequencing & erection process. A 3D model spatially represents 3 dimensional data which can be utilized to highlights and updates all discussions around erection. The structural engineers will be able to “zoom in” on several structural elements within the model.
  
BIM effectively creates coordination between the fabricated steel and the other building components to minimize the on-site problems and cut down the increasing cost of steel erection.

BIM facilitates structural engineers to observe the status of each of the steel pieces in the supply chain resulting better management of the erection portion of the project as well as just-in-time fabrication, save substantial amounts of time off of erection schedules.



 
A BIM model can be utilized to generate 2D shop fabrication & jobsite erection drawings containing accurate qty's, piece marks and dimensional placement. The model can also be applied to coordinate field layout points detained on the actual jobsite matched up to what was detailed and designed in the model.

A data and information enriched BIM model also produces material lists (ABM), piece counts, CNC files to surpass to the shop to be applied for digital fabrication & erection.

BIM is utilized as a 3D reference and communication tool to better represent and demonstrate design and RFI issues during the fabrication and erection stages of the project.

BIM provides added value to the construction procedures by ensuring that the exact precast elements are delivered and erected on time during the detailing, fabrication and erection phases. A BIM model can also avoid expensive erection delays.

BIM supervise development of detailing, fabrication & erection and also plan for erection coordination and planning to make sure that equipment and fabrication deliveries appear in the right sequence.   

A BIM model plays a vital role to verify probable errors within a plant design before the commencing of fabrication and erection phases. Any comments can be put directly to the 3D model to underscore and expose problem areas.   

BIM presents information in a graphical view ensuring fastest communication among team members and better understanding of overall project status.

BIM provides erection-synchronized steel delivery by assessing and developing atypical connections, observing where and how special load conditions are supported in a superior way, wherever a visual architectural objective is accomplished applying less metal and labor.

MEP engineers can make their pre-fabrication process more efficient with BIM based pipe-spool drawing

Spool drawings are assembly drawings which contain comprehensive manufacturing and fabrication information for each unique “spool piece”. Piping spools are generally represented in symbolic isometric drawings. Spool drawings are produced from a BIM model in 3D representation, line representation, and symbolic form along with 2D plans, sections and isometric views. BIM can automatically assign spool assembly drawings with bill of material data.



The piping spool drawings can be utilized for accurate pre-fabrication off-site / on-site compliant with contractors’ pre-fabricating standards and preferences.



A spool drawing may contain dimensions and angles, a bill of materials, and manufacturing information.

Spool drawings provide the following information :-
  • 2-D or isometric view of the spool piece producing adequate features for manufacturing.
  • Sections are given if necessary.
  • Bill of material for fabrication
  • Field installation information, for example a line tag number and field tie-in numbers
  • Suggest support spacing

    BIM based shop drawing shows how the building structure will perform at the early stage of design

    Now-a-days shop drawings are considered to be the part and parcel of every construction project. The contractor, supplier, manufacturer, real estate developer, subcontractor, or fabricator create shop drawing to be utilized for pre-fabricated components like elevators, structural steel, trusses, pre-cast, windows, appliances, cabinets, air handling units, millwork etc . Shop drawings generate enormously vital information about measures and specifications of pre-fabricated components. MEP engineers also require the installation and coordination shop drawings that range from sheet metal ductwork, piping, plumbing, fire protection, and electrical.

    The shop drawing refers to the drawn version of information provided by the Manufacturer or Contractor. These informations are exposed in the construction documents. The shop drawing is required to provide details of the fabrication and/or installation of the items to the manufacturer’s production crew or contractor's installation crews.

    The shop drawing is the only place in the project document where all the connection details are shown with specifications to resolve connection issues. As for instance, a properly designed BIM wall system facilitates a much larger percentage of material to be pre-cut to accurate dimensions off-site, which lead to considerable savings in material and labor.



    Now with BIM or Building Information System, the contractor can produce 3D shop drawings in which a 3D model can be directly applied for assembly and installation to forecast how the building structure will perform at the early stage of design. A 3D shop drawing contains huge database of information which can be applied for selecting the best construction technique to achieve the best possible output. To get rid of future design inconsistencies and radical changes as the general contractor arranges the BIM model while integrating shop drawings from the different trades, the architects and engineers evaluate shop drawings to ensure that the contractors, manufactures and suppliers have understood the design objective in the same sense.
    The different kinds of shop drawings :-

    • SHOP / COORDINATION DRAWINGS
    • Coordinated HVAC Shop Drawings
    • Sheet Metal Fabrication Shop Drawings
    • Piping Shop and Fabrication Drawings
    • Coordinated mechanical Room Shop drawing
    • Coordinated plumbing shop drawing
    • Electrical Shop Drawings
    • MEP Coordination Drawings
    • Fabrication spool drawing
    • Sleeve & Rough opening drawing
    • 2D mechanical coordination drawing
    • MEP(3D)/BIM (4D) Mech coordination drawings

    Process :-
    Submit →Coordinate→Approve→Fabricate→Install
