Redlining construction drawings is a process that involves reviewing and marking up construction drawings to identify errors, inconsistencies, and missing information.  The purpose of redlining is to ensure that the construction drawings accurately represent the design intent and meet the necessary standards and codes.

During the redlining process, an experienced construction professional, such as an architect, engineer, or contractor, carefully reviews each drawing and compares it to the project specifications and other relevant documents.  They use a red pen or other marking tool to identify any issues or discrepancies, such as missing dimensions, incorrect materials, or conflicting details.  I prefer an old fashioned red pen to any digital tools made for redlining.  However, many clients prefer the use of Procore or Blubeam as they find it easier for their organizations to share files.

Redlining can also involve adding notes, comments, and corrections to the drawings, indicating changes that need to be made before construction can begin.  The redlined drawings are then used by the construction team to make the necessary adjustments and ensure that the final product meets the required standards.

Redlining construction drawings is a crucial step in the construction process, as it helps to prevent errors, reduce construction delays, and ensure that the final product is safe, functional, and aesthetically pleasing.  It requires attention to detail, technical knowledge, and a thorough understanding of the design and construction process.
