Frequently Asked Questions
What are the Rebar Shop drawing or Placing drawings or Rebar submittal drawings?
Placing drawings are working drawings that show the number, size, length, and location of the reinforcing steel necessary for the placement and fabrication of the material. Placing drawings can comprise plans, details, elevations, schedules, material lists, and bending details. They can be prepared manually or by computer.
Purpose of the Rebar Shop drawing or Placing drawings or Rebar submittal drawings?
Placing drawings are intended to convey the A/E’s intent as covered in the contract documents. The contract documents plus any additions, such as addenda issued by the A/E (per terms agreed on in the contract if issued after the contract is made), constitute the sole authority for information in placing drawings. The placing drawings must include all information necessary for the complete fabrication and placing of all reinforcing steel.
Procedure to create the Rebar Shop drawing or Placing drawings or Rebar submittal drawings?
Placing drawings are prepared by a detailer in accordance with the A/E’s instructions contained in the contract documents. Any necessary, additional information must be supplied by the contractor concerning field conditions, field measurements, construction joints, and sequence of placing concrete. After approval by the A/E, including necessary revisions, the drawings may be used by the fabricator and placer.
What is a Bar lists
Bar lists used in cutting, bending, tagging, shipping, and invoicing are prepared from placing drawings. Bars are grouped separately on the bar list as follows: 1. Straight. 2. Bent, including stirrups and ties; and 3. Spirals. The grade of reinforcing steel for all items must be shown. Straight bars are usually grouped according to size, with the largest size first and those of the same size listed in the order of their length with the longest bar first. Bent bars, stirrups, and ties are usually listed in a similar We provide these in various formats excel , aSa , Soule , etc
What is Dimensional Drawing?
General arrangement drawings (GA’s) present the overall composition of an object such as a building. Depending on the complexity of the building, this is likely to require a number of different projections, such as plans, sections , and elevations, and may be spread across several different drawings. They may be referred to as 'location drawings' as they show the location of various components and assemblies within the overall design, it has showing coordinate point for all structural elements like slab, beam, column, shear wall and stair case. It has showing location of opening with size and reference distance from grid line or column/shear wall/concrete wall or slab edge. It has showing curve of slab edge, radius General arrangement drawings are likely to be prepared at each stage of development of a building design, showing the overall relationship between the main elements and key dimensions. The level of detail will increase as the project progresses and they may need to be supplemented by more detailed drawings, showing specific elements and assemblies. On very simple projects these may be included on the general arrangement drawings themselves, but generally, separate drawings will be required. General arrangement drawings may include references to additional information, such as specifications and detail drawings, however they should not duplicate information included elsewhere as this can become contradictory and may cause confusion. They may also include notation and symbols. It is important that these are consistent with industry standards so that their precise meaning is clear and can be understood. The scale at which drawings are prepared should reflect the level of detail of the information they are required to convey. Different line thicknesses can be used to provide greater clarity for certain elements. They may be drawn to scale by hand, or prepared using Computer Aided Design (CAD) software. However, increasingly, building information modelling (BIM) is being used to create 3 dimensional representations of buildings and their components.
What is the difference between GA drawings and shop drawings?
General arrangement drawing General Drawing is mostly used in the construction industry to show the scaled view of an object such as a building, slab plan, stair case layout etc. The purpose of creating a GA drawing is to present the overall composition of the product through different plans, sections, and elevations. Depending on the complexity of such projects, the design information seems to spread across several different drawings. Since engineers use such drawings to represent and locate various parts and showing coordinates of element with place it on field accurately. General arrangement drawings are also known as Location Drawings. Shop Drawings General Arrangement drawings show various components of the product through different projections, elevations, and plans. On the other hand, shop drawings help you understand how the involved components will be placing of reinforcement, bar bending schedule and installation. It is prepared by contractors, subcontractors, suppliers, manufacturers, and fabricators. These stakeholders receive design intent drawings and design specifications from the designers. With the shared information, shop drawings are developed to show the correct rebar drawings, fabrication, assembly, and product installation.
