Issued for Construction (IFC) drawings are 2D drawings issued to contractors by architects or consultants in the final stages of the design process.
IFC drawings describes general details of construction and allows contractors to bid on estimated prices, labor, materials, equipment, etc. to complete the task.
Characteristics of IFC Drawing
Drawings involved in a construction project go through a variety of purposes such as bidding, issue for approval (IFA) and issue for construction (IFC).
Do not confuse IFC drawings with Good for Construction (GFC) drawings. A GFC is a blueprint and specifications intended for a project and approved by local government authorities and the customer.
After the contract is signed, the general contractor requests a series of “issue for construction” documents.
IFC drawings are included in this IFC set. The consultant will issue the IFC drawings and documents (IFC set) to the contractor as part of the contract documents and contracts. IFC drawings are therefore verified by an approved department or client and marked as “issued for construction”. His IFC mark on contract documents indicates that the documents are ready for construction.
IFC drawings are used to create shop drawings. A shop drawing is a more detailed drawing of a construction job that provides a “how-to” guide. A shop drawing shows a detailed design of a particular part or unit under construction.
Manufacturing drawings are prepared by contractors, manufacturers, and suppliers. All manufacturing drawings are IFC drawings, but not all IFC drawings are manufacturing drawings.
IFC drawings do not reflect actual site conditions. It has been revised and revised several times since its publication. These days, both IFC and manufacturing drawings can be extracted from the BIM model. The IFC Sets option helps architects create sets for internal use in contract management. Reduce the effort involved in creating and reviewing PDFs for output to contractors.
All manufacturing drawings are extracted from specific his IFC drawings. As such, IFC drawings play an important role in building projects, helping to detail detailed areas of structural design. A project stakeholder prepares her IFC drawings on site prior to construction, whether the project is residential, commercial or industrial.
