How Carl Stahl ARC GmbH Uses Bluebeam Revu

July 2026

Carl Stahl ARC GmbH uses Bluebeam Revu, to make the quotation process significantly more efficient. Missing measurements are derived directly from PDF drawings, solutions are visualised faster, and coordination is streamlined. This saves 30–40% of the time spent preparing quotes, improves the quality of the proposals, and makes Bluebeam an integral part of the daily workflow.

Challenge

The company often received initial customer inquiries based on PDF drawings that did not yet contain all the dimensions relevant for the calculation. In the past, PDF drawings often had to be laboriously transferred to other programs or edited manually, which took a lot of time and was prone to errors. Initial solutions and concepts had to be elaborately visualised in separate documents and made available to the customer.

Solution

With Bluebeam Revu, these drawings can be quickly scaled and missing dimensions such as lengths, areas or square meters can be determined directly from the documents - precisely and without additional CAD licences. Bluebeam Revu also adds sketches and concept proposals directly to the drawing. With the help of prepared network structures, possible solutions can be quickly visualised.

Results

Using Bluebeam Revu for precise mass calculations enables the team to create reliable cost estimates and offers. In addition, a clearer idea of the final end result is already created in the bidding phase, giving the company a decisive advantage for consulting, coordination and decision-making.

Use in project management and design

Approved customer drawings are often provided as PDFs and processed directly in Bluebeam for redlining, comments or change markings, for example, if last-minute adjustments are required on the construction site.

This allows coordination with customers to be implemented quickly and transparently. In addition, Carl Stahl ARC uses Bluebeam Revu across projects to digitally sign documents such as contracts or releases.

"If we look at the tasks we cover with Bluebeam Revu today , we get a time saving of about 30 to 40 percent. This is an enormous added value for us. Bluebeam has become an integral part of our everyday work and accompanies our sales and project teams every day – around one to two hours per employee," explains Christian Hummel, Research and Innovation at Carl Stahl ARC GmbH

Why Carl Stahl ARC chooses Bluebeam Revu

The decision was based on the combination of ease of use, Bluebeam Revu's features specifically designed for the construction and architecture industry, and the ability to use these features efficiently without having to provide each sales rep or project manager with their own CAD licence.

"The quality of our offerings has improved significantly with Bluebeam Revu. Today, we work more precisely and are less prone to errors, because we derive quantities, linear meters and square meters directly from the customer's drawing and can immediately create a reliable offer from them," says Christian Hummel.

Together into the digital future

For more than 20 years, the cooperation between Carl Stahl ARC GmbH and NTI Deutschland GmbH has been characterised by trust, continuity and close exchange. Together, solutions were developed that sustainably improve everyday work and are tailored to the needs of practice.

This partnership will continue to gain importance in the future: The focus is on consistent digitalisation, the expansion of BIM-based working methods and the use of AI to make processes even more efficient, networked and simpler.
