Redline Drawings and As-Builts

December 21, 2022

Redline drawings are one of the most important documents to have on hand as a construction project is underway. This document will show the progress of the work, and help the team stay on track. Having a good record of redline drawings will help make sure the work is done on time and budget.

As-built drawings

As-built redline drawings, also known as record drawings, are the drawings that show changes in construction. Usually, an architect is responsible for making these drawings.

Redline drawings are drafted according to proper drafting standards. The drawings are printed on full size paper. However, a contractor is not usually involved in creating them.

During construction, the contractor will mark up changes to the original construction drawings. These changes should include new values, sizing, material type, installation notes and dimensions. They are then incorporated into the as-built drawings.

The final as-built drawings are then submitted to the client for approval. If there are any issues with the drawings, they should be addressed as soon as possible. By maintaining a neat set of as-builts, the company can enhance its image and make it easier to land future jobs.

Record drawings, on the other hand, are the result of the architect's review and approval. Generally, these drawings are more reliable than as-built drawings.

As-builts are not official plans

As-builts are drawings that show the state of a project as it was built. These documents are used to document any changes made during construction or renovation. For instance, if you plan to convert retail space to offices, you need to make sure your building plans include entry and exit doors, as well as restrooms.

As-builts are also necessary for obtaining a certificate of occupancy. The permit process is simpler when the as-builts are up to date. This allows for future modifications to be done smoothly. Aside from helping streamline the permitting process, an up-to-date set of as-builts can help contractors do better business.

One of the easiest ways to achieve an as-built is to use a cloud-based data management system. This provides teams with real-time access to the data, allowing them to upload documentation from their mobile devices on the fly.

Another method of as-built creation is using collaborative software. Construction software can assemble the as-builts, reducing the time and effort required to create them.

Signing procedures for redline drawings

When a construction project involves multiple disciplines and the need for numerous redline drawings, an effective redlining process is critical. Having an automated process to track changes helps avoid time-consuming holdups and rework, while improving contract finalization.

A redline is a document or drawing that represents a change from the original design. The term is used most often in the context of contract negotiation. It can also be used in other situations where there are multiple groups involved in the agreement, such as when a new template is being created.

Redline drawings are reviewed and checked by a Project Manager and QA/QC Manager. After approval, they are handed over to an As-Built Preparation Team.

In the case of an IFC/Shop Drawing, the changes need to be incorporated to reflect the field conditions. The changes are documented and incorporated into the Project Redline Package Register. This information is recorded and maintained by the DCC.

During construction, the Site Engineer marks any deviations from the approved Redline Drawing. Upon verification, the PMT informs the Project Manager.

Keeping track of redline drawings

Keeping track of redline drawings is a crucial part of the design process. Whether you are an architect or a contractor, you need to know how to make sure you understand the changes that have occurred to the plans. If you don't, you may end up with a construction project that isn't completed properly. Here are some ways you can do it.

When you are working on a building, it is common to make changes to the project as you go along. These changes can be due to a variety of reasons. For example, there may be a new city building code that has to be followed. You may also need to update your drawings to reflect client changes or the addition of design team members.

One way to keep track of the as-built is to make sure you have an index sheet for each project. This way, you will have a document that shows the original and updated design of the project.
