Construction Bid Drawings & IFC Support

Construction tender drawings are drawings issued with bid documents to communicate the proposed design and scope to bidders. A set may include plans, elevations, sections, details, schedules, and drawing references; the required documents depend on the project and procurement requirements.

On a drawing issue, IFC usually means “Issued for Construction”: the drawing status assigned for construction use after the project's required design reviews and approvals. It is distinct from an IFC model file, where IFC means Industry Foundation Classes, an open BIM data format.

Tender drawings are issued to support pricing and bid review. Issued-for-construction drawings are a later issue of the design intended for construction, subject to the project's approval process. The drawing status, revision, and permitted use should be stated in the project issue requirements.

The package should include the drawings and schedules required by the bid documents, commonly plans, elevations, sections, details, and a drawing register. The exact list varies by project. We confirm the sheet list, source information, formats, revision rules, and review milestones with the tender team before drafting.

Yes, updates can be scoped after award. The team needs the approved post-tender design changes, accepted comments, and current revision requirements. We update only the agreed sheets and issue the files using the status and approval process defined by the responsible project team.

Provide the latest design files or PDFs, drawing list, project standards, title blocks, schedules, tender brief, required formats, and bid issue date. Also identify known changes and the person responsible for design decisions. We review the inputs and flag missing information during scoping.

No. Ten days is a target timeline, not a guarantee. The schedule depends on the agreed sheet count and scope, complete inputs, timely decisions, and review availability. We confirm the planned milestones after reviewing the package.

Depending on the agreed scope, deliverables can include AutoCAD DWG, Revit RVT, and PDF files. The tender team should confirm the required formats, templates, naming conventions, and issue procedure before work starts.

The responsible design professional and project stakeholders review and approve drawings under the project's contract and local requirements. Our drafting support does not replace professional design responsibility, regulatory approval, or a required professional seal.

We work from the addenda and revision instructions supplied by the tender team, record agreed changes against the drawing list, and return files using the naming and revision conventions agreed for the project. The team should identify superseded documents to avoid working from outdated information.

Pricing depends on the drawing list, sheet count, source-file condition, disciplines, level of detail, deliverable formats, and required issue date. Share the available files and bid requirements to request a scope-based quotation.
