Optical character recognition (OCR) software help convert non-editable document formats such as PDFs, images, or paper documents into machine-readable formats that are editable & searchable.

OCR applications are commonly used to capture text from PDFs & images and convert the text into editable formats such as Word, Excel, or a plain text file. OCR is also used to digitise files and documents to make them searchable.

OCR software that leverage AI/ML capabilities can also help automate data capture from scanned documents/images. AI-based document processing can digitize the data in convenient, editable formats that fit into organizational workflows.

Construction management is a highly specialized and complex process that requires the coordination of many moving parts involving humans, resources, and teams all the while working on strict timelines to complete the construction project on time and within budget. Given the strict timelines construction projects operate under, many construction teams are turning to technology to speed up certain processes. In particular, the construction industry is turning to OCR software so that they can quickly digitize and convert all their documents into editable format.

Construction OCR software can scan and process all types of construction documents such as construction application forms, project plans, blueprints, engineering drawings, construction completion certificates, etc.

A good construction OCR software has to be able to automate the document processing workflow of all construction documents to reduce manual workload, eliminate errors, and save time.

Here are some of the best Construction OCR software in 2024. We will also check out some free OCR software.

What is OCR in Construction?

OCR, or Optical Character Recognition, is becoming more and more pivotal in the construction industry. This technology is useful in managing all types of construction documents such as construction application forms, project plans, blueprints, engineering drawings, construction completion certificates, etc.

OCR technology involves the use of software that can recognize and read printed or handwritten text or images and convert them into digital form. OCR technology has been around for several decades, but recent advances in artificial intelligence and machine learning have made it more accurate and reliable than ever before. OCR technology is particularly useful in construction projects, where multiple different types of documents are used daily, and would reduce processing times tremendously if digitized.

One of the biggest advantages of OCR technology is that it can help reduce errors and improve the accuracy of data entry. When humans enter data manually, they are prone to making mistakes such as typos, misspellings, and transpositions. These errors can have serious consequences, particularly in construction projects where accuracy is critical for the project to stay on time and within budget. OCR technology can help eliminate these errors by automating the data entry process and reducing the need for human intervention.
