For over a decade, we have overcome the limitations and set new standards for the cooling and efficiency of data centers around the world by offering proprietary technologies.

Air cooling

A new look at old technology. We reviewed the approach and implementation of air cooling for large data centers. We were able to immediately solve several problems of air cooling. We reduced power consumption and significantly reduced the noise of our data centers

Design & construction of data centers

Our mission is to create new and technically advanced data centers for any purpose. We use only the perfect technology to implement the projects of our customers and the main characteristics for us are quality and reliability.

Virtual Design & Construction

Cutting edge technology and innovative thinking makes us better builders. We use the BIM model and other tools to capture and coordinate all project information to build efficiently and with the highest quality. Our in-house team uses advanced technology including 3D/4D modeling, laser scanning, drone flights, logistics planning, collision detection, quantity extraction, visual rendering, and virtual quality walks. More information to help analyze and visualize the project early-on leads to better decisions and outcomes in the field.


Our mission is to address the communication gap, as prefabricated materials reduce overall schedule time, improve quality, reduce waste, reduce local labor needs, and provide safer, more organized workplaces. Holder works with our design partners and sales partners to evaluate options for configuration, skidding, modularity, and off-site production to select the best build strategy for each system. We use VDC, working packaging, and other tools to optimize this process for our customers and partners.

Planning & Design Support

We help bridge the communication gap that can sometimes exist between architects and contractors through project planning, design and execution. We leverage our experience and expertise to turn your vision into defined project goals. Our team provides constructability and interdisciplinary review feedback during design when it is most impactful to limit your risk in construction. We continually collaborate with the design team to feed the field during construction the right information at the right time to turn your building over to you on time.

Safety & Risk Management

Our clients entrust us with their safety, security and reputation. Safety on the jobsite and in the offices is our top priority every day. Our goal is to send every member of every project team home safely to their families every night.

Through early collaboration with the client, we take a comprehensive approach to identify and mitigate potential project risks. We develop a plan of action to manage those risks accordingly for the best outcome on the project.
